The main objective was to determine the comparability of these tests in classifying PML risk. Eligible patients were selected from a database, and all specimens for the STRATIFY JCV™ DxSelect™ and IMMUNOWELL™ JCV antibody tests were collected on the same day. Patients were classified into three risk categories (low, intermediate, or high) based on threshold values for each test. </p> <p> Results: The analysis showed 85.5% agreement between the two tests for risk classification. Ten discordant cases were identified, mainly between intermediate- and high-risk categories. Compared to STRATIFY JCV™ DxSelect™, IMMUNOWELL™ JCV antibody test tended to categorize more patients as higher risk. No significant association was found between discordance and prior use of immunosuppressant drugs and >24 doses of natalizumab. The agreement between tests, assessed with the weighted Cohen’s Kappa coefficient, was substantial (&#954;=0.6222). </p> <p> Conclusions: Compared to the STRATIFY JCV™ DxSelect™, the IMMUNOWELL™ JCV test tends to place more patients in higher risk categories. Further, longitudinal studies are needed to evaluate the clinical impact of these differences in PML risk assessment.</p>]]></description> </item><item><title><![CDATA[Advances in Imaging Techniques of the Blood-brain Barrier and Clinical
Application]]></title><link>https://www.benthamscience.comarticle/131322</link><description><![CDATA[The blood-brain barrier (BBB) is an important structure that maintains the normal function of the central nervous system (CNS). The functional structure of BBB is closely related to diseases of CNS, including degenerative diseases, brain tumours, traumatic brain injury, stroke, etc. Imaging methods were commonly used to monitor the integrity of BBB, such as DCE-MRI, DSC-MRI, and PET, this contributes to understand the process of related diseases and develop appropriate treatment options. In recent years, many studies had shown that the MRI methods (ASL, IVIM, CEST, etc.) could evaluate blood-brain barrier function, which use endogenous contrast agents and become an increasingly great concern. Another image methods (FUS, uWB-eMPs) can open up the normal BBB, allowing macromolecular drugs across the locally opening BBB, which could be beneficial to the treatment of some brain diseases. In this review, we briefly introduce the theory of BBB imaging modalities and its clinical application.]]></description> </item><item><title><![CDATA[SERAC1 Deficiency- A New Phenotype]]></title><link>https://www.benthamscience.comarticle/134548</link><description><![CDATA[Introduction: SERAC1 deficiency phenotype range from MEGD(H)EL syndrome, the most severe, to juvenile complicated spastic paraplegia, to adult-onset dystonic features (in only one patient). The MEGD(H)EL syndrome is characterized by (3-methylglutaconic aciduria with deaf-ness-dystonia, [hepatopathy], encephalopathy, and Leigh-like syndrome). Biochemical abnormali-ties: elevated urinary 3 – metilglutaconic and 3-metilglutaric acids, high lactate and alanine in se-rum. Diagnosis is confirmed when biallelic pathogenic variants in SERAC1 gene are found. Brain MRI: basal ganglia lesions and generalized atrophy. <P> Results/Case Report: A 30-year-old patient with a moderate intellectual disability, developed, since the age of 25, a progressive loss of previous capacities (hand dexterity, oral language), and later subacute generalized dystonic features. Currently he has spastic tetraparesis, dystonia, scoliosis and autistic behavior, with bilateral basal ganglia lesions on brain MRI. Genetic study revealed biallelic pathogenic variants in SERAC1 gene, confirm MEGD(H)EL. A 73 years old patient with cognitive impairment and progressive spastic tetraparesis had multiple periventricular T2 hyperintense le-sions. She has a homozygotic SERAC1 variant NM_032861: exon4:c.T139A: p.F471 (rs112780453), considered benign. Biochemical study revealed elevated plasmatic alanine and uri-nary3-metilglutaconic and 3-metilglutaric acid. This profile is concordant with mitochondrial dys-function and SERAC1 Deficit. <P> Conclusion: The first patient has the clinical symptoms associated to the MEGD(H)EL syndrome, and the biochemical and genetic confirmation of the diagnosis, without reservations. However, in the second patient, the progressive paraparesis and cognitive impairment did not appear to be caused by multiple sclerosis nor subcortical vascular leukoencephalopathy (without vascular risk factors). The abnormal biochemical profile is suggestive of SERAC1 Deficiency, even without genetic con-firmation. In what should we believe?]]></description> </item><item><title><![CDATA[A Review on the Efficacy and Safety of Intrathecal Administration of
Novel Medications for Leptomeningeal Metastases in Solid Cancers]]></title><link>https://www.benthamscience.comarticle/131605</link><description><![CDATA[Leptomeningeal disease (LMD) is a rare and lethal manifestation that may occur in the advanced stages of solid tumors and hematological malignancies. With advances in diagnostic techniques, the detection and confirmation of the presence of LMD have increased. Although its optimal treatment remains a challenge, the use of the intrathecal route for the delivery of novel therapeutics is now considered a promising drug delivery strategy to complement radiation and systemic-based therapies. Although methotrexate, cytarabine, and thiotepa have a long history in the treatment of LMD, other medications have also been shown to be beneficial. In this article, we have reviewed the effects of novel medications administered via the intrathecal route for the treatment of solid tumors. We have searched PubMed, Scopus, and Google Scholar databases till the end of September 2021 using the following keywords: “leptomeningeal disease”, “leptomeningeal carcinomatosis”, “leptomeningeal metastases”, “solid tumors”, “solid cancers”, and “intrathecal”. Our literature findings have uncovered that most studies on LMD, which occurs secondary to solid cancers, are available as ‘case reports’, and few clinical trials have been conducted to date. Single-drug (monotherapy) or combination drug therapy, administered via the intrathecal route, especially in metastatic breast and lung cancer, has been shown to improve patients' symptoms and overall lifespan, while exhibiting a low and acceptable prevalence of side effects. However, judgments/conclusions about the effectiveness and safety of these drugs still require further clinical evaluation.]]></description> </item><item><title><![CDATA[Neurological Complications Caused by Human Immunodeficiency Virus (HIV) and Associated Opportunistic Co-infections: A Review on their
Diagnosis and Therapeutic Insights]]></title><link>https://www.benthamscience.comarticle/130488</link><description><![CDATA[Neurocognitive disorders associated with human immunodeficiency virus (HIV) infected individuals increase the risk of mortality and morbidity that remain a prevalent clinical complication even in the antiretroviral therapy era. It is estimated that a considerable number of people in the HIV community are developing neurological complications at their early stages of infection. The daily lives of people with chronic HIV infections are greatly affected by cognitive declines such as loss of attention, learning, and executive functions, and other adverse conditions like neuronal injury and dementia. It has been found that the entry of HIV into the brain and subsequently crossing the blood-brain barrier (BBB) causes brain cell damage, which is the prerequisite for the development of neurocognitive disorders. Besides the HIV replication in the central nervous system and the adverse effects of antiretroviral therapy on the BBB, a range of opportunistic infections, including viral, bacterial, and parasitic agents, augment the neurological complications in people living with HIV (PLHIV). Given the immuno-compromised state of PLHIV, these co-infections can present a wide range of clinical syndromes with atypical manifestations that pose challenges in diagnosis and clinical management, representing a substantial burden for the public health system. Therefore, the present review narrates the neurological complications triggered by HIV and their diagnosis and treatment options. Moreover, coinfections that are known to cause neurological disorders in HIV infected individuals are highlighted.]]></description> </item><item><title><![CDATA[Bipolar Disorder and Manic-Like Symptoms in Alzheimer’s, Vascular and
Frontotemporal Dementia: A Systematic Review]]></title><link>https://www.benthamscience.comarticle/125016</link><description><![CDATA[<P>Background: An increased risk of manic episodes has been reported in patients with neurodegenerative disorders, but the clinical features of bipolar disorder (BD) in different subtypes of dementia have not been thoroughly investigated. <P> Objectives: The main aim of this study is to systematically review clinical and therapeutic evidence about manic syndromes in patients with Alzheimer’s disease (AD), vascular dementia (VaD), and frontotemporal dementia (FTD). Since manic-mixed episodes have been associated to negative outcomes in patients with dementia and often require medical intervention, we also critically summarized selected studies with relevance for the treatment of mania in patients with cognitive decline. <P> Methods: A systematic review of the literature was conducted according to PRISMA guidelines. PubMed, Scopus, and Web of Science databases were searched up to February 2022. Sixty-one articles on patients with AD, VaD, or FTD and BD or (hypo) mania have been included. <P> Results: Manic symptoms seem to be associated to disease progression in AD, have a greatly variable temporal relationship with cognitive decline in VaD, and frequently coincide with or precede cognitive impairment in FTD. Overall, mood stabilizers, and electroconvulsive therapy may be the most effective treatments, while the benefits of short-term treatment with antipsychotic agents must be balanced with the associated risks. Importantly, low-dose lithium salts may exert neuroprotective activity in patients with AD. <P> Conclusion: Prevalence, course, and characteristics of manic syndromes in patients with dementia may be differentially affected by the nature of the underlying neurodegenerative conditions.</P>]]></description> </item><item><title><![CDATA[Cognitive Deficits: Verbal and Semantic Fluency in People Living with
HIV and AIDS]]></title><link>https://www.benthamscience.comarticle/132496</link><description><![CDATA[<p>Background: Since the beginning of the HIV epidemic, the virus has taken millions of lives worldwide. The United Nations AIDS Fund’s statistics reported that deaths caused by HIVrelated conditions and AIDS were about 39 million from the beginning of the epidemic to 2015. The united global efforts to fight the virus are considerably changing the indicators, such as mortality and morbidity, but the challenges remain. The total number of people living with HIV in Bulgaria as of 12th May, 2015, was 2,121. As of 30th November, 2016, the official data reported 2 460 people living with HIV. As of 13th February, 2017, 2 487 individuals were HIV-seropositive. Approximately 60% of people with HIV are prone to developing cognitive impairment due to the infection. <p> Objective: This study aimed to know the level of cognitive deficiency, in particular, the verbal and semantic fluency of people living with HIV and AIDS. <p> Methods: In this study, a comparative analysis was carried out. The Stewart test was used to compare the average independent samples. For clarity, the average values, the test statistics, and the estimated significance levels are presented in the tables. Additionally, a statistical mechanism of factor selection was used by the forward stepwise method. The Wilks' Lambda statistic reported values between 0 and 1, with values close to zero indicating good discrimination of the model. <p> Results: According to this research, the HIV positives participants generated fewer verbs than the ones from the control group. The data were partially confirmed by the present study. There were differences in terms of both adjectives and nouns among people living with HIV and AIDS. <p> Conclusion: The study data proves that language deficits are detectable in neurocognitive testing of HIV. The overall hypothesis of the study has been confirmed. The language impairments are primarily qualitative and can be used as a marker for the initial and subsequent therapy assessment.</p>]]></description> </item><item><title><![CDATA[Imaging Markers of Neurologic Damage in COVID-19: A Systematic
Review]]></title><link>https://www.benthamscience.comarticle/124955</link><description><![CDATA[<p>Background and Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection commonly leads to neurologic manifestations. In the present review, we aimed to investigate potential neuroimaging markers of early diagnosis and prognosis of neurologic manifestations in COVID-19. <p> Methods: Our study was registered in the Prospective Register of Systematic Reviews (PROSPERO) under the protocol CDR42021265443. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we selected 51 studies for whole-manuscript analysis. <p> Results: Magnetic resonance imaging (MRI) was the most common imaging method. The pattern, sites of lesion, signs, and symptoms of neurologic injury varied. Such manifestations possibly resulted from a direct viral infection or, most likely, from indirect mechanisms including coagulation disturbances, hypoxemia, and immunological responses. <p> Conclusion: The heterogeneity of the studies precludes any generalization of the findings. Brain MRI is the most informative imaging exam. Population studies, including the entire spectrum of COVID-19 are missing. There is still a need for future population studies evaluating neurologic manifestations of all COVID-19 severities acutely and chronically.</p>]]></description> </item><item><title><![CDATA[Safety and Monitoring of the Treatment with Disease-Modifying Therapies
(DMTs) for Multiple Sclerosis (MS)]]></title><link>https://www.benthamscience.comarticle/122488</link><description><![CDATA[<p>Background: Disease-Modifying Therapies (DMTs) for Multiple Sclerosis (MS) are widely used given their proven efficacy in the relapsing form of the disease, while recently, Siponimod and Ocrelizumab have been approved for the progressive forms of the disease. Currently, 22 diseasemodifying drugs are approved by the FDA, while in 2012, only nine were present in the market. From March 2019 until August 2020, six new drugs were approved. This rapid development of new DMTs highlighted the need to update our knowledge about their short and long-term safety. <p> Objective: This review summarizes the available safety data for all the Disease-Modifying Therapies for Multiple Sclerosis and presents the monitoring plan before and during the treatment. <p> Methods: A literature search was conducted using PUBMED and COCHRANE databases. Key journals and abstracts from major annual meetings of Neurology, references of relevant reviews, and relative articles were also manually searched. We prioritized systematic reviews, large randomized controlled trials (RCTs), prospective cohort studies, and other observational studies. Special attention was paid to guidelines and papers focusing on the safety and monitoring of DMTs. <p> Conclusion: Data for oral (Sphingosine 1-phosphate (S1P) receptor modulators, Fumarates, Teriflunomide, Cladribine), injectables (Interferons, Glatiramer acetate, Ofatumumab), and infusion therapies (Natalizumab, Ocrelizumab, Alemtuzumab) are presented.</p>]]></description> </item><item><title><![CDATA[Hypomyelination with Atrophy of Basal Ganglia and Cerebellum (HABC)
Due to UFM1 Mutation in Roma Patients - Severe Early Encephalopathy
with Stridor and Severe Hearing and Visual Impairment. A Single
Center Experience]]></title><link>https://www.benthamscience.comarticle/121036</link><description><![CDATA[<p> Background: Hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) is a neurodegenerative disease with neurodevelopmental delay, motor, and speech regression, pronounced extrapyramidal syndrome, and sensory deficits due to TUBB4A mutation. In 2017, a severe variant was described in 16 Roma infants due to mutation in UFM1. </p> <p> Objective: The objective of this study is to expand the clinical manifestations of H-ABC due to UFM1 mutation and suggest clues for clinical diagnosis. </p> <p> Methodology: Retrospective analysis of all 9 cases with H-ABC due to c.-273_-271delTCA mutation in UFM1 treated during 2013-2020 in a Neuropediatric Ward in Plovdiv, Bulgaria. </p> <p> Results: Presentation is no later than 2 months with inspiratory stridor, impaired sucking, swallowing, vision and hearing, and reduced active movements. By the age of 10 months, a monomorphic disease was observed: microcephaly (6/9), malnutrition (5/9), muscle hypertonia (9/9) and axial hypotonia (4/9), progressing to opisthotonus (6/9), dystonic posturing (5/9), nystagmoid ocular movements (6/9), epileptic seizures (4/9), non-epileptic spells (3/9). Dysphagia (7/9), inspiratory stridor (9/9), dyspnea (5/9), bradypnea (5/9), apnea (2/9) were major signs. Vision and hearing were never achieved or lost by 4-8 mo. Neurodevelopment was absent or minimal with subsequent regression after 2-5 mo. Brain imaging revealed cortical atrophy (7/9), atrophic ventricular dilatation (4/9), macrocisterna magna (5/9), reduced myelination (6/6), corpus callosum atrophy (3/6) and abnormal putamen and caput nuclei caudati. The age at death was between 8 and 18 mo. </p> <p> Conclusion: Roma patients with severe encephalopathy in early infancy with stridor, opisthotonus, bradypnea, severe hearing and visual impairment should be tested for the Roma founder mutation of H-ABC in UFM1. </p>]]></description> </item><item><title><![CDATA[Changes in John Cunningham Virus Index in Multiple Sclerosis Patients
Treated with Different Disease-Modifying Therapies]]></title><link>https://www.benthamscience.comarticle/118811</link><description><![CDATA[<p>Background: Progressive Multifocal Leukoencephalopathy (PML) is an opportunistic infection caused by John Cunningham virus (JCV) reactivation, potentially associated with natalizumab (NTZ) treatment for Multiple Sclerosis (MS). The anti-JCV antibodies titre (JCV index) increases during NTZ treatment; however, the effects of other disease-modifying therapies (DMTs) on the JCV index have not been fully explored. <p> Objective: The aim of the study was to evaluate changes in the JCV index during treatment with several DMTs. <p> Methods: This longitudinal study evaluated the JCV index before starting DMT (T0) and during treatment with DMT (T1). <p> Results: A total of 260 participants (65.4 % females, mean age 43 ± 11.3 ) were enrolled: 68 (26.2 %) treated with fingolimod (FTY), 65 (25 %) rituximab or ocrelizumab (RTX/OCR), 37 (14.2 %) dimethyl-fumarate (DMF), 29 (11.2 %) cladribine (CLD), 23 (8.8 %) teriflunomide (TFM), 20 (7.7 %) interferon or glatiramer acetate (IFN/GA), and 18 (6.9 %) alemtuzumab (ALM). At T1, the percentage of patients with JCV index <0.90 was found to be significantly increased in the ALM group (16.7 % versus 66.7 %, p = 0.05), while the percentage of patients with JCV index >1.51 was found to be significantly reduced in the RTX/OCR group (51.6 % versus 37.5 %, p = 0.04). In the FTY group, a significant reduction in the percentage of patients with JCV index <0.90 was also found (23.5 % versus 1.4 %, p = 0.0006). The mean JCV index was reduced in the RTX/OCR and ALM groups, while a significant increase was observed in the FTY group. <p> Conclusion: DMTs with a T and/or B depleting mechanism of action induced a significant reduction in the JCV index. These results may suggest new possible sequencing strategies potentially maximizing disease control while reducing the PML risk.</p>]]></description> </item><item><title><![CDATA[Levamisole-Induced Leukoencephalopathy in Russia: Analysis of 30 Cases]]></title><link>https://www.benthamscience.comarticle/119682</link><description><![CDATA[<p>Aims: The study aims to raise medical specialists’ awareness regarding the severity of possible complications of levamisole administration, and demonstrate the role of accurate medical history collection in a differential diagnosis. <p> Background: Levamisole, an anthelmintic drug with immunomodulatory effects, has long been used worldwide till the early 2000s, when its association with demyelinating leukoencephalopathy was established. However, in the developing countries, it is still widely used for the prevention and treatment of helminthic invasion in humans. The actual prevalence of levamisole-induced multiple inflammatory leukoencephalopathy (LEV-induced MIL) in Russia remains unknown, and therefore, the study of its frequency and characteristics is indisputably important. <p> Objectives: The objective of this study is to determine the clinical features and MRI findings of levamisole- induced MIL in the Russian population, and to analyse the frequency of diagnostic errors at the initial assessment. <p> Methods: A single-center retrospective analysis of total 30 patients who were diagnosed with LEV- induced MIL and attended the Research Center of Neurology was conducted. Inclusion criteria were 1) clinically: acute or subacute polysymptomatic onset of neurological disturbances, 2) MRI: multifocal demyelinating lesion with no evidence of dissemination in time, 3) anamnestic data: levamisole exposure from 2 to 8 weeks before symptoms onset as well as monophasic disease course (absence of relapses according to follow up assessments up to 3 years). <p> Results: Clinically, presentation with constitutional symptoms including headache, fever, fatigue and myalgia, focal motor disturbances and dysarthria prevailed in our cohort. On the brain MRI, multiple foci of demyelination with simultaneous gadolinium enhancement were observed. The link between neurological symptoms and levamisole intake has often been detected only during follow- up assessments. Patients were most often misdiagnosed with acute disseminated encephalomyelitis, stroke and multiple sclerosis. In most cases, LEV-induced MIL was successfully treated with intravenous corticosteroids and/or plasma exchange (PLEX), however, residual neurologic symptoms were preserved in some patients. Additionally, two detailed clinical cases of patients being initially misdiagnosed are presented in the article. <p> Conclusion: The differential diagnosis remains difficult for suspected cases of LEV-induced MIL that could lead to delayed therapy initiation, and consequently incomplete recovery. Growing evidence suggests that a single administration of levamisole even in low doses might potentially lead to severe neurological deficit or death. Therefore, changes in medication management policies are required in order to prevent the uncontrolled use of levamisole.</p>]]></description> </item><item><title><![CDATA[miR-27b-3p is Highly Expressed in Serum of Patients with Preeclampsia
and has Clinical Significance]]></title><link>https://www.benthamscience.comarticle/119305</link><description><![CDATA[<p>Background: Preeclampsia (PE) is defined as a salient complication of late pregnancy. microRNAs (miRNAs) have emerged as critical biological regulators in PE. This study determined miR-27b-3p expression in serum of PE patients and investigated its clinical significance in PE. <p> Methods: This study enrolled a total of 130 pregnant women, including 90 PE patients (51 mild PE and 39 severe PE) and 40 healthy controls. miR-27b-3p expression in the serum of PE patients and healthy controls was detected using RT-qPCR. The correlation among miR-27b-3p expression and 24-h urine protein, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine, and fetal birth weight was analyzed using Pearson's correlation coefficient. The targeting relationship between miR-27b-3p and PPARG was verified. PPARG protein level in PE patients was detected using ELISA kits. The predictive efficiency of miR-27b-3p and PPARG in PE was analyzed using the receiver operating characteristic (ROC) curve. <p> Results: Compared to normal pregnant women, PE pregnant women, especially severe PE patients, had higher miR-27b-3p expression. miR-27b-3p was positively correlated with 24-h urine protein, SBP, DBP, and serum creatinine but negatively correlated with fetal birth weight. PPARG was poorly expressed in PE patients and negatively correlated with miR-27b-3p. ROC curve showed that both miR-27b-3p and PPARG had good predictive efficacy on PE. <p> Conclusion: miR-27b-3p expression in serum of pregnant women with PE was positively correlated with the severity of PE symptoms, suggesting the involvement of miR-27b-3p in PE occurrence.</p>]]></description> </item><item><title><![CDATA[Update on Myositis Therapy: From Today’s Standards to Tomorrow’s Possibilities]]></title><link>https://www.benthamscience.comarticle/118843</link><description><![CDATA[Inflammatory myopathies, in short, myositis, are heterogeneous disorders that are characterized by inflammation of skeletal muscle and weakness of arms and legs. Research over the past few years has led to a new understanding regarding the pathogenesis of myositis. The new insights include different pathways of the innate and adaptive immune response during the pathogenesis of myositis. The importance of non-inflammatory mechanisms such as cell stress and impaired autophagy has been recently described. New target-specific drugs for myositis have been developed and are currently being tested in clinical trials.

Derived from a Neurology Department along with Literature Review]]></title><link>https://www.benthamscience.comarticle/117523</link><description><![CDATA[Background: Natalizumab is a humanized monoclonal antibody with high efficacy and an acceptable safety profile used in the treatment of patients with multiple sclerosis (MS). <p> Objective: Our aim was to report data regarding long-term administration of Natalizumab in patients with Relapsing-Remitting Multiple Sclerosis (RRMS) from our clinic. <p> Methods: A retrospective observational study was performed including RRMS patients who underwent treatment with ≥ 24 Natalizumab infusions. We analyzed EDSS values, the relapse rate and the rate and type of adverse events related to Natalizumab administration. <p> Results: 51 subjects were included with a predominance of women (62.74%), with an average age of 40.43±1.49 years, a mean disease duration of 9.86±0.7 years and mean number of Natalizumab infusions of 45.58±2.74. An increased number of patients (80.39%) were relapse-free and a mild reduction of the mean EDSS value following Natalizumab initiation in patients who had not been treated with other disease modifying therapies anteriorly was observed. Among the encountered adverse events such as increased liver transaminases (13.72%), local infections (7.84%) and dysmenorrhea in one patient were registered in this study. The rate of severe adverse events was 3.92 and no cases of Progressive Multifocal Leukoencephalopathy (PML) were registered. <p> Conclusion: Natalizumab proves to be effective, has an adequate safety profile and can be administered with good tolerability for a rather extended period of time, provided that the patients are closely monitored.]]></description> </item><item><title><![CDATA[Immunosuppressant Drugs and Covid-19: Associated Risks, Drug-Drug Interactions and Contraindications]]></title><link>https://www.benthamscience.comarticle/115901</link><description><![CDATA[Immunosuppressant drugs like Etanercept, Mycophenolate mofetil, Sirolimus, Cyclosporine, and Rituximab can weaken the immune system and make patients susceptible to SARS nCoV-2 virus. These drugs make immunocompromised persons more vulnerable to complications associated with COVID-19. Moreover, it can also increase mortality and morbidity, as a weakened immune system can lead to a longer duration of infection. This study discusses the guidelines on immunosuppressant drugs and their associated risk factors with COVID-19, issued by the U.S CDC (Centers for Disease Control and Prevention), WHO (World Health Organization), U.S FDA (Food and Drug Administration), and other accredited global health organizations. Moreover, it also includes information about pharmaceutical properties, mechanism of action, COVID-19 associated risk factors, adverse drug reactions, contraindications, and drug-drug interactions. Our study will help government partners and international health organizations to understand COVID-19 health risks associated with immunosuppressants. Increased public awareness about effective drug therapy for autoimmune diseases, cancer treatment, immunocompromised, and organ transplant patients will help lower the mortality and morbidity associated with the disease amid the COVID-19 pandemic.]]></description> </item><item><title><![CDATA[Experimental Rodent Models of Vascular Dementia: A Systematic Review]]></title><link>https://www.benthamscience.comarticle/113140</link><description><![CDATA[Vascular Dementia (VaD) occurs due to cerebrovascular insufficiency, which leads to decreased blood circulation to the brain, thereby resulting in mental disabilities. The main causes of Vascular Cognitive Impairment (VCI) are severe hypoperfusion, stroke, hypertension, large vessel disease (cortical), small Vessel Disease (subcortical VaD), strategic infarct, hemorrhage (microbleed), Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), and Cerebral Amyloid Angiopathy (CAA), which leads to decreased cerebrovascular perfusion. Many metabolic disorders such as Diabetes Mellitus (DM), dyslipidemia, and hyperhomocysteinemia are also related to VaD. The rodent experimental models provide a better prospective for the investigation of the molecular mechanism of new drugs. A plethora of experimental models are available that mimic the pathological conditions and lead to VaD. This review article updates the current knowledge on the basis of VaD, risk factors, pathophysiology, mechanism, advantages, limitations, and the modification of various available rodent experimental models.]]></description> </item><item><title><![CDATA[Targeting Microglial Polarization to Improve TBI Outcomes]]></title><link>https://www.benthamscience.comarticle/110092</link><description><![CDATA[Traumatic Brain Injury (TBI) is still the worldwide leading cause of mortality and morbidity in young adults. Improved safety measures and advances in critical care have increased chances of surviving a TBI, however, numerous secondary mechanisms contribute to the injury in the weeks and months that follow TBI. The past 4 decades of research have addressed many of the metabolic impairments sufficient to mitigate mortality, however, an enduring secondary mechanism, i.e. neuroinflammation, has been intractable to current therapy. Neuroinflammation is particularly difficult to target with pharmacological agents due to lack of specificity, the blood brain barrier, and an incomplete understanding of the protective and pathologic influences of inflammation in TBI. Recent insights into TBI pathophysiology have established microglial activation as a hallmark of all types of TBI. The inflammatory response to injury is necessary and beneficial while the death of activated microglial is not. This review presents new insights on the therapeutic and maladaptive features of the immune response after TBI with an emphasis on microglial polarization, followed by a discussion of potential targets for pharmacologic and non-pharmacologic treatments. In aggregate, this review presents a rationale for guiding TBI inflammation towards neural repair and regeneration rather than secondary injury and degeneration, which we posit could improve outcomes and reduce lifelong disease burden in TBI survivors.]]></description> </item><item><title><![CDATA[Natural Bioactives as Potential Therapeutic Modalities Against NeuroAIDS]]></title><link>https://www.benthamscience.comarticle/115294</link><description><![CDATA[With the introduction of antiretroviral therapy, the worldwide AIDS-related deaths have decreased, and life expectancy has increased, including the prevalence of AIDS-related neurological disorders or neuroAIDS. HIV-associated neurocognitive disorders such as mild neurocognitive disorder and asymptomatic neurocognitive impairment have largely remained stable or increased among the HIV-infected individuals in the combination antiretroviral therapy era. The emerging evidence that antiretrovirals with high CNS penetration effectiveness score contribute to the neurotoxicity and HIV-associated neurocognitive disorders has ushered the search for natural, nontoxic bioactive constituents having pre-established neuroprotective, anti-inflammatory, and restorative neurocognitive activity. In this review, we have highlighted the probable mechanism of neuroAIDS infection, the problem with the existing antiretroviral therapy, along with various bioactive constituents with in vivo, in vitro, or ex vivo evidence of their neuroprotective activity that can be used as an adjuvant with the current combination antiretroviral therapy regimen or can even serve as an alternate to the antiretrovirals for treatment of HIV associated neurocognitive disorder.]]></description> </item><item><title><![CDATA[An Overview of the &#945;4&#946;1 Integrin and the Potential Therapeutic Role of its Antagonists]]></title><link>https://www.benthamscience.comarticle/114309</link><description><![CDATA[This article presents a simplified view of integrins with emphasis on the α4 (&#945;4&#946;1/VLA-4) integrin. Integrins are heterodimeric proteins expressed on the cell surface of leukocytes that participate in a wide variety of functions, such as survival, growth, differentiation, migration, inflammatory responses, tumour invasion, among others. When the extracellular matrix is degraded or deformed, cells are forced to undergo responsive changes that influence remodelling during physiological and pathological events. Integrins recognize these changes and trigger a series of cellular responses, forming a physical connection between the interior and the outside of the cell. The communication of integrins through the plasma membrane occurs in both directions, from the extracellular to the intracellular (outside-in) and from the intracellular to the extracellular (inside-out). Integrins are valid targets for antibodies and small-molecule antagonists. One example is the monoclonal antibody natalizumab, marketed under the name of TYSABRI®, used in the treatment of recurrent multiple sclerosis, which inhibits the adhesion of α4 integrin to its counter-receptor. &#945;4&#946;1 Integrin antagonists are summarized here, and their utility as therapeutics are also discussed.]]></description> </item><item><title><![CDATA[Delayed Multiple Non-ischemic Cerebral Enhanced Lesions After Endovascular Therapy For Left Internal Carotid Aneurysm: A Case Report]]></title><link>https://www.benthamscience.comarticle/113553</link><description><![CDATA[<p>Introduction: Endovascular therapy (EVT) for intracranial arterial aneurysms is depicted with several complications. Very recently, delayed non-ischemic cerebral enhanced (NICE) lesions have been identified as a rare complication associated with EVT. This complication always stands a higher chance of being missed in asymptomatic patients. We report a case of multiple NICE lesions in a known chronic hepatitis B infection and chronic gastritis patient with left internal carotid aneurysm (ICA) treated with detachable coils. </P><P> Case Presentation: A 52 years old female with left ICA was treated with detachable coils via the endovascular route. Three weeks after the operation, she presented with numbness of her right limbs which was persistent and waked her up from sleep each night. She admitted skin allergies after wearing metals except for gold and silver since childhood. MRI revealed multiple abnormal lesions in the left temporal lobe, hippocampus, insula, and parietal lobe and some perifocal edema which were consistent with the diagnosis of delayed NICE lesions. </P><P> Conclusion: It is very important to report the occurrences of these lesions in literature because of their allergic origin. We advocate that allergy to metals especially those used in coating endovascular equipment should be evaluated before every EVT for intracranial aneurysms.</p>]]></description> </item><item><title><![CDATA[Role of C1QBP/p32 and its Therapeutic Potential in Breast Carcinoma and other Cancers]]></title><link>https://www.benthamscience.comarticle/112889</link><description><![CDATA[The complement component 1, q subcomponent binding protein (C1QBP/gC1q-R/p32/HABP1/TAP/YBAP1), is a ubiquitous, multifunctional protein. C1QBP localizes mainly to mitochondria due to its N-terminal mitochondrial localization signal, but it can also be found in different subcellular compartments including the cell surface, nucleus, cytoplasm, and extracellular space. C1QBP has been reported to interact with a variety of proteins that have apparently unrelated functions. C1QBP has also been observed to interact with hyaluronic acid and RNA. These findings suggest that C1QBP has both mitochondrial and extramitochondrial functions. The C1QBP binding sites of many partner proteins are located within basic and intrinsically disordered regions of these molecules, consistent with the hypothesis that C1QBP functions as a molecular chaperone. C1QBP expression is elevated in various types of human cancers, including breast cancer. Moreover, it has been implicated in the development, progression, and metastasis of cancer cells based on loss-of-function and gain-of-function studies using cancer cell lines and xenograft models. Hence C1QBP could be a molecular target in breast cancer therapy. Studies using antibodies, tumor homing peptides such as LyP-1, and small molecules that target C1QBP warrant further investigation as C1QBP is a potential therapeutic target.]]></description> </item><item><title><![CDATA[Design, Sar, and Metabolism Study of Crucifereae Family Compound (Spirobrassinin) and its Analogs for Antiangiogenic Potential Targeting Hsp90]]></title><link>https://www.benthamscience.comarticle/108771</link><description><![CDATA[<p>Background: “Angiogenesis”, a major oncogenic signaling pathway, has been termed to be the most fascinating area of cancer therapy. Viewing this, the molecular chaperone Hsp90 has surfaced as a potential molecular target due to being vitally engrossed in sustaining stability, integrity, and functions of crucial proteins involved in multiple signaling pathways of tumor progression and metastasis. </P><P> Objective: The study set sights on virtual screening (molecular docking and PreADMET study), MD simulation, and metabolism study of compounds from Crucifereae family along with the intensive structure-activity relationship studies in search of potent lead targeting HSP90. </P><P> Methods: All the chemical structures were drawn using ChemDraw and converted into suitable 3D-structures. The target protein, HSP90 was retrieved from RCSB PDB. All the compounds of Crucifereae family and analogs were subjected to Lipinski’s rule of five and ADMET prediction using Molinspiration and PreADMET software respectively. The screened compounds were further exposed to MD simulation and metabolism studies. </P><P> Conclusion: The docking results showed the promising inhibitory potential of Ana51 against Hsp90 with the binding energy of -11.32 kcal/mol as compared to its parent compound ‘spirobrassinin’ and a known inhibitor ‘Ganetespib’ exhibiting binding energy of -7.57 kcal/mol and -9.83 kcal/mol respectively. Optimization, flexibility prediction, and ascertaining the stability of Hsp90 in complex with the ligands were done by means of Molecular Dynamics (MD) simulations for 50 ns. The Hsp90-Ana51 complex exhibited stability with an RMSD value of 0.15 nm and Rg value to be 1.62 nm. The investigation further extends towards the SOM analysis of Ana51 to forecast the probable toxic and non-toxic in vivo metabolites via in silico tools (SMARTCyp, Xenosite Web, and PASS online server). </P><P> Results: Ana 51 came out to be metabolically stable withstanding phase I metabolism and producing non-toxic metabolites compared to the parent compound and the standard drug. Obtained results propose Ana51 as a novel anti-Hsp90 lead compound with exceptional antiangiogenic capability.</p>]]></description> </item><item><title><![CDATA[The Rapidly Changing Composition of the Global Street Drug Supply and its Effects on High-risk Groups for COVID-19]]></title><link>https://www.benthamscience.comarticle/113618</link><description><![CDATA[<P>Background: Globally, an alarming number of pharmaceutically active compounds are now routinely added to the street drugs of abuse, cocaine and heroin. In some cases, seventeen (17) or more potentially toxic compounds are found in a single street purchased bag or block of cocaine or heroin. Pharmacologically active compounds, impurities, or breakdown products from drug manufacturing and industrial chemicals (collectively referred to as toxic adulterants) are now found in street drugs. They include, but are not limited to: antipsychotics, antidepressants, anxiolytics, antihistamines, anthelmintics, anesthetics, antiinflammatorys, antipyretics, analgesics, antispasmodics, antiarrhythmics, antimalarials, veterinary medications, bronchodilators, expectorants, sedatives, muscle relaxers, natural/synthetic hallucinogens, decongestants, new psychoactive substances (NPS), industrial compounds, fungicides, and impurities in the manufacturing process. All can be found within a single street purchase of heroin or cocaine. Routine clinical or workplace drug testing will not detect all these toxic adulterants. Only specialty forensic tests, specifically ordered, will detect them. The synergistic effect on the human body of such an unprecedented combination of pharmacologically active compounds is unknown and potentially deadly. This is especially seen in daily substance users who are exposed to these combinations multiple times a day over an extended period of time. Individuals with substance use disorders (SUDs) have several co-occurring health problems that make them more susceptible to COVID-19, including compromised immune, pulmonary, cardiovascular, and respiratory systems. These problems are high-risk factors for the acquisition of COVID-19 infection and more serious complications from the virus, including hospitalization and death. </P><P> Objective: The study aims to bring to the attention of public health officials, addiction medicine specialists, treatment officials, therapists, and the general public the alarming increase of dangerous toxic adulterants being added to street drugs and their potentially lethal synergistic effects. Also, it aims to provide insights into how these new formulations can have serious pathophysiological effects on individuals with Substance Abuse Disorders (SUDs) during the COVID-19 pandemic. </P><P> Methods: The literature on street drug cutting agents, toxic adulterants, NPS, manufacturing byproducts, and other industrial compounds will be reviewed. Also, a review of the literature of pathophysiological effects, especially on SUD patients, in light of the COVID-19 pandemic will be presented. This is combined with international and USA studies that were carried out by the Colombo Plan that identified these new combinations of toxic adulterants in street drugs, using state-of-the-art field and forensic laboratory detection technologies. </P><P> Results: The majority of street drugs, in some cases more than ninety-five percent, now have multiple toxic adulterants. It is rare that a street purchase of cocaine or heroin does not contain multiple toxic adulterants, cutting agents, NPS, manufacturing byproducts, or industrial chemicals. </P><P> Conclusion: This dangerous new composition in world street drug supply is unprecedented and may be the undetected cause of many psychostimulant and opioid overdose deaths, as many toxic adulterants are not routinely tested in post-mortem or street drug seizure cases. In addition, several of these toxic adulterants create a catastrophic drop in white blood cells, causing neutropenia and making the substance users susceptible to a wide range of opportunistic infections, including COVID-19. This profound change in the world street drug supply has catastrophic implications for individuals with SUDs and our health care system, especially in the era of the COVID-19 pandemic.</P>]]></description> </item><item><title><![CDATA[Ideational Fluency in Patients with Rheumatoid Arthritis]]></title><link>https://www.benthamscience.comarticle/111666</link><description><![CDATA[Background: Neuropsychiatric symptoms have been well documented in several systemic inflammatory conditions, for example, systemic lupus erythematosus (SLE). Increased prevalence of cognitive decline and psychiatric issues has been reported in patients with rheumatoid arthritis (RA). However, there is limited evidence of which exact cognitive domains are affected and to what degree. </p> Aim: To test the performance of cognition in the domain of ideational fluency (Thing Categories Test in particular) in patients with RA and compare the results with the general population and to the results with cognitive and depression screening scores in both groups. </p> Methods: Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7) assessment, Montreal Cognitive Assessment (MoCA), and Thing Categories Test (TCT) were used to evaluate patients with RA, as well as the control group. </p> Results: Twenty patients with RA and 20 controls were tested, with 7 and 4 men, and 13 and 16 women in the study and control group, respectively. Average scores in TCT at three minutes were 7.50 (IQR6.0-10.0) and 6.0 (IQR3.0-8.0) for category “blue”; 17.50 (IQR15.0-19.0) and 16.0 (10.0-18.0) for category “round” in the control and study group, respectively. A statistically significant difference was established between the study and the control group in TCT for the category “blue” (p<0.025). The average score for GAD7 was 2.0 (IQR 0.0-5.75) and 3.0 (IQR0.50-6.00) in the control and study group, respectively. The average score for PHQ-9 was 2.0 (IQR0.25-4.75) and 4.0 (IQR2.00-5.50) in the control and study group, respectively. Finally, the average score for the MoCA scale was 27.0 (IQR25.25-28.00) and 26.0 (IQR23.50-28.00) in the control and study group, respectively. </p> Conclusion: Preliminary evidence suggests that RA at least partially affects the cognitive domain of ideational fluency. However, further research with larger experimental groups is needed to provide more conclusive evidence.]]></description> </item><item><title><![CDATA[Newborn Screening through TREC, TREC/KREC System for Primary Immunodeficiency with limitation of TREC/KREC. Comprehensive Review]]></title><link>https://www.benthamscience.comarticle/108729</link><description><![CDATA[<P>Introduction: Newborn screening (NBS) by quantifying T cell receptor excision circles (TRECs) and Kappa receptor excision circles in neonatal dried blood spots (DBS) enables early diagnosis of different types of primary immune deficiencies. Global newborn screening for PID, using an assay to detect T-cell receptor excision circles (TREC) in dried blood spots (DBS), is now being performed in all states in the United States. In this review, we discuss the development and outcomes of TREC, TREC/KREC combines screening, and continued challenges to implementation. </P><P> Objective: To review the diagnostic performance of published articles for TREC and TREC/ KREC based NBS for PID and its different types. </P><P> Methods: Different research resources were used to get an approach for the published data of TREС and KREC based NBS for PID like PubMed, Scopus, Google Scholar, Research gate EMBASE. We extracted TREC and KREC screening Publisher with years of publication, content and cut-off values, and a number of retests, repeat DBS, and referrals from the different published pilot, pilot cohort, Case series, and cohort studies. </P><P> Results: We included the results of TREC, combined TREC/KREC system based NBS screening from different research articles, and divided these results between the Pilot studies, case series, and cohort. For each of these studies, different parameter data are excluded from different articles. Thirteen studies were included, re-confirming 89 known SCID cases in case series and reporting 53 new SCID cases in 3.15 million newborns. Individual TREC contents in all SCID patients were <25 TRECs/μl (except in those evaluated with the New York State assay). </P><P> Conclusion: TREC and KREC sensitivity for typical SCID and other types of PID was 100 %. It shows its importance and anticipating the significance of implementation in different undeveloped and developed countries in the NBS program in upcoming years. Data adapting the screening algorithm for pre-term/ill infants reduce the amount of false-positive test results.</P>]]></description> </item><item><title><![CDATA[Purines and Pyrimidines: Metabolism, Function and Potential as Therapeutic Options in Neurodegenerative Diseases]]></title><link>https://www.benthamscience.comarticle/112185</link><description><![CDATA[Various neurodegenerative disorders have various molecular origins but some common molecular mechanisms. In the current scenario, there are very few treatment regimens present for advanced neurodegenerative diseases. In this context, there is an urgent need for alternate options in the form of natural compounds with an ameliorating effect on patients. There have been individual scattered experiments trying to identify potential values of various intracellular metabolites. Purines and Pyrimidines, which are vital molecules governing various aspects of cellular biochemical reactions, have been long sought as crucial candidates for the same, but there are still many questions that go unanswered. Some critical functions of these molecules associated with neuromodulation activities have been identified. They are also known to play a role in foetal neurodevelopment, but there is a lacuna in understanding their mechanisms. In this review, we have tried to assemble and identify the importance of purines and pyrimidines, connecting them with the prevalence of neurodegenerative diseases. The leading cause of this class of diseases is protein misfolding and the formation of amyloids. A direct correlation between loss of balance in cellular homeostasis and amyloidosis is yet an unexplored area. This review aims at bringing the current literature available under one umbrella serving as a foundation for further extensive research in this field of drug development in neurodegenerative diseases.]]></description> </item><item><title><![CDATA[Molecular Genetics of Early- and Late-Onset Alzheimer’s Disease]]></title><link>https://www.benthamscience.comarticle/111715</link><description><![CDATA[Alzheimer’s disease (AD) is the most common form of dementia in the elderly and this complex disorder is associated with environmental as well as genetic factors. Early-onset AD (EOAD) and late-onset AD (LOAD, more common) are major identified types of AD. The genetics of EOAD is extensively understood, with three gene variants such as APP, PSEN1, and PSEN2 leading to the disease. Some common alleles, including APOE, are effectively associated with LOAD identified, but the genetics of LOAD is not clear to date. It has been accounted that about 5-10% of EOAD patients can be explained through mutations in the three familiar genes of EOAD. The APOE &#949;4 allele augmented the severity of EOAD risk in carriers, and the APOE &#949;4 allele was considered as a hallmark of EOAD. A great number of EOAD patients, who are not genetically explained, indicate that it is not possible to identify disease-triggering genes yet. Although several genes have been identified by using the technology of next-generation sequencing in EOAD families, including SORL1, TYROBP, and NOTCH3. A number of TYROBP variants are identified through exome sequencing in EOAD patients and these TYROBP variants may increase the pathogenesis of EOAD. The existence of the &#949;4 allele is responsible for increasing the severity of EOAD. However, several &#949;4 allele carriers propose the presence of other LOAD genetic as well as environmental risk factors that are not identified yet. It is urgent to find out missing genetics of EOAD and LOAD etiology to discover new potential genetic facets which will assist in understanding the pathological mechanism of AD. These investigations should contribute to developing a new therapeutic candidate for alleviating, reversing and preventing AD. This article, based on current knowledge, represents the overview of the susceptible genes of EOAD, and LOAD. Next, we represent the probable molecular mechanism that might elucidate the genetic etiology of AD and highlight the role of massively parallel sequencing technologies for novel gene discoveries.]]></description> </item><item><title><![CDATA[Autosomal Recessive Hereditary Spastic Paraplegia: A Rare Case of a Family with Phenotypic Variation]]></title><link>https://www.benthamscience.comarticle/112365</link><description><![CDATA[<P>Background: Hereditary spastic paraplegia is a neurodegenerative disorder with a pure and complex form. More than 50 genetic types are currently known, with different ages of onset for characteristic symptoms. Data regarding hereditary spastic paraplegia remain scarce, and the rare subtype of spastic paraplegia type 5 is no exception. </P><P> Objective: This report presents data regarding the case of a single family, from the city of Djerba, with five individuals affected with hereditary spastic paraplegia, the largest number of spastic paraplegia type 5 mutated family members so far reported in current literature. </P><P> Methods: To emphasize the importance of genetic testing, we retrospectively reviewed a familial confirmed case of hereditary spastic paraplegia. Clinical features of family members were described. </P><P> Results: The family presents a large phenotypic variation that, in part, differs from the known phenotypic presentations. Age of onset and clinical manifestation showed interfamilial variations. The alteration found in CYP7B1 (c.1081C>T; p.R361*) may help emphasize the importance of genetic testing and the much-needed treatment options already in use in current neurological practice. </P><P> Conclusion: The understanding of the molecular pathways of hereditary spastic paraplegia, together with the establishment of disease biomarkers, will hopefully lead to better and more personalized treatment.</P>]]></description> </item><item><title><![CDATA[Neuro-AIDS: Current Status and Challenges to Antiretroviral Drug Therapy (ART) for Its Treatment]]></title><link>https://www.benthamscience.comarticle/107090</link><description><![CDATA[<P>Introduction: The infiltration of HIV into the brain alters the functions of the nervous system known as Neuro-AIDS. It leads to neuronal defects clinically manifested by motor and cognitive dysfunctions. </P><P> Materials and Methods: Current antiretroviral therapy can prevent viral replication but cannot cure the disease completely. HAART-Highly active antiretroviral therapy is used for the treatment of HIV infection. Challenges in neuro-AIDS therapy are as shown in the graphical abstract. One of the challenges is latent viral reservoirs like the brain; which act as a sanctuary site for viruses. Nearly ~50% of HIV patients show neuropathological signs. Nervous system related disorders, including AIDS dementia, sensory neuropathy, and myelopathy have a 25% of prevalence in patients having access to a highly active combination of antiretroviral therapy. </P><P> Results and Conclusions: Brain is one of the viral sanctuary sites for HIV. The current need of neuro-AIDS therapy is to target the brain as a viral reservoir. Drugs should cross or bypass the blood-brain barrier to reach the brain with effective concentrations. Current research on novel drug delivery approaches may prove helpful in treating neuro-AIDS and related disorders effectively.</P>]]></description> </item><item><title><![CDATA[Exploring Multiple Sclerosis (MS) and Amyotrophic Lateral Scler osis (ALS) as Neurodegenerative Diseases and their Treatments: A Review Study]]></title><link>https://www.benthamscience.comarticle/110197</link><description><![CDATA[<P>Growing concern about neurodegenerative diseases is becoming a global issue. It is estimated that not only will their prevalence increase but also morbidity and health burden will be concerning. Scientists, researchers and clinicians share the responsibility of raising the awareness and knowledge about the restricting and handicapping health restrains related to these diseases. </P><P> Multiple Sclerosis (MS), as one of the prevalent autoimmune diseases, is characterized by abnormal regulation of the immune system that periodically attacks parts of the nervous system; brain and spinal cord. Symptoms and impairments include weakness, numbness, visual problems, tingling pain that are quietly variable among patients. </P><P> Amyotrophic Lateral Sclerosis (ALS) is another neurodegenerative disease that is characterized by the degeneration of motor neurons in the brain and spinal cord. Unlike MS, symptoms begin with muscle weakness and progress to affect speech, swallowing and finally breathing. Despite the major differences between MS and ALS, misdiagnosis is still influencing disease prognosis and patient’s quality of life. </P><P> Diagnosis depends on obtaining a careful history and neurological examination as well as the use of Magnetic Resonance Imaging (MRI), which are considered challenging and depend on the current disease status in individuals. </P><P> Fortunately, a myriad of treatments is available now for MS. Most of the cases are steroid responsive. Disease modifying therapy is amongst the most important set of treatments. </P><P> In ALS, few medications that slow down disease progression are present. The aim of this paper is to summarize what has been globally known and practiced about MS and ALS, as they are currently classified as important growing key players among autoimmune diseases. In terms of treatments, it is concluded that special efforts and input should be directed towards repurposing of older drugs and on stem cells trials. As for ALS, it is highlighted that supportive measurements and supplementary treatments remain essentially needed for ALS patients and their families. On the other hand, it is noteworthy to clarify that the patient-doctor communication is relatively a cornerstone in selecting the best treatment for each MS patient.</P>]]></description> </item><item><title><![CDATA[Bortezomib – First Therapeutic Proteasome Inhibitor for Cancer Therapy: A Review of Patent Literature]]></title><link>https://www.benthamscience.comarticle/105582</link><description><![CDATA[<P>Background: Bortezomib is a reversible inhibitor of proteasome proteins in mammalian cells. Bortezomib is proven to be cytotoxic to a number of tumor cells by disrupting their normal homeostatic mechanism and thereby, causing cell death. Currently, Bortezomib is prescribed for patients with multiple myeloma and mantle cell lymphoma. </P><P> Objective: This assessment highlights the overview of the recent patents of Bortezomib. This review includes patents grouped in sections like product patents, process patent, composition related patents as well as the treatment methodology. The objective of this article is to facilitate researchers with all existing patents at a single place. </P><P> Methods: Data were searched from various online databases. In which, paid databases include SciFinder® and Orbit®. Free databases include Patentscope® (WIPO), Worldwide Espacenet® (EPO), Google Patents and InPASS (Indian patent database). </P><P> Results: Several new processes and composition related patents of Bortezomib have been recently patented as its orange-book listed patents are going to soon expire during July 2022. Further, due to the problem of oxidation during development and long-term storage of Bortezomib formulation, a number of excipients are tried in these patents to stabilize the same. However, there is still a need for further development of an improved formulation of Bortezomib with better characteristics. </P><P> Conclusion: Extensive research has been carried out on various processes for preparing Bortezomib and the composition thereof.

IBD is based on progressive damage to the inflamed gut tissue. As its pathogenesis remains unknown, recent accumulating data have demonstrated that IBD is a complex and multi-factorial disorder correlated with host luminal factors, which lead to an imbalance between pro- and anti-inflammatory signaling. The growing understanding of the molecular mechanisms responsible for IBD has suggested a wide range of potential therapeutic targets to treat this condition. Some patients do not have a satisfactory response to current therapeutic medications such as antitumor necrosis factor (TNF) agents, or their response decreases over time. As a result, IBD therapeutics have been changed recently, with several new agents being evaluated. The identification of various inflammatory cascades has led to forming the idea to have novel medications developed. Medications targeting Janus kinases (JAK), leukocyte trafficking Interleukin (IL) 12/23, and Sphingosine 1 phosphate (S1P) are among these newly developed medications and highlight the role of microbial-host interaction in inflammation as a safe promising strategy. This systematic review aims to summarize different molecular targeting therapeutics, the most potent candidates for IBD treatment in recent studies.]]></description> </item><item><title><![CDATA[Gene Therapy Approaches in an Autoimmune Demyelinating Disease: Multiple Sclerosis]]></title><link>https://www.benthamscience.comarticle/105047</link><description><![CDATA[Multiple Sclerosis (MS) is the most common autoimmune demyelinating disease of the Central Nervous System (CNS). It is a multifactorial disease which develops in an immune-mediated way under the influences of both genetic and environmental factors. Demyelination is observed in the brain and spinal cord leading to neuro-axonal damage in patients with MS. Due to the infiltration of different immune cells such as T-cells, B-cells, monocytes and macrophages, focal lesions are observed in MS. Currently available medications treating MS are mainly based on two strategies; i) to ease specific symptoms or ii) to reduce disease progression. However, these medications tend to induce different adverse effects with limited therapeutic efficacy due to the protective function of the blood-brain barrier. Therefore, researchers have been working for the last four decades to discover better solutions by introducing gene therapy approaches in treating MS generally by following three strategies, i) prevention of specific symptoms, ii) halt or reverse disease progression and iii) heal CNS damage by promoting remyelination and axonal repair. In last two decades, there have been some remarkable successes of gene therapy approaches on the experimental mice model of MS - experimental autoimmune encephalomyelitis (EAE) which suggests that it is not far that the gene therapy approaches would start in human subjects ensuring the highest levels of safety and efficacy. In this review, we summarised the gene therapy approaches attempted in different animal models towards treating MS.]]></description> </item><item><title><![CDATA[Overview of Periodic Safety Update Reports: Where Have We Reached?]]></title><link>https://www.benthamscience.comarticle/100438</link><description><![CDATA[Periodic safety update report (PSUR) is now known as the Periodic Benefit-Risk Evaluation Report (PBRER).

As a hereditary form of SVD with early onset, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) represents a pure form of SVD and may thus serve as a model disease for SVD. To date, underlying molecular mechanisms linking vascular pathology and subsequent neuronal damage in SVD are incompletely understood. </P><P> Objective: We performed comparative transcriptional profiling microarray and proteomic analyses on post-mortem frontal lobe specimen from 2 CADASIL patients and 5 non neurologically diseased controls in order to identify dysregulated pathways potentially involved in the development of tissue damage in CADASIL. </P><P> Methods: Transcriptional microarray analysis of material extracted from frontal grey and white matter (WM) identified subsets of up- or down-regulated genes enriched into biological pathways mostly in WM areas. Proteomic analysis of these regions also highlighted cellular processes identified by dysregulated proteins. </P><P> Results: Discrepancies between proteomic and transcriptomic data were observed, but a number of pathways were commonly associated with genes and corresponding proteins, such as: “ribosome” identified by upregulated genes and proteins in frontal cortex or “spliceosome” associated with down-regulated genes and proteins in frontal WM. </P><P> Conclusion: This latter finding suggests that defective expression of spliceosomal components may alter widespread splicing profile, potentially inducing expression abnormalities that could contribute to cerebral WM damage in CADASIL.</P>]]></description> </item><item><title><![CDATA[Safety Profiles and Pharmacovigilance Considerations for Recently Patented Anticancer Drugs: Advanced Thyroid Cancer]]></title><link>https://www.benthamscience.comarticle/99988</link><description><![CDATA[<P>Background: Thyroid cancer is the most common endocrine neoplasia and represents approximately 1.5% to 2.1% of all cancers diagnosed annually worldwide. Iodine Refractory Differentiated Thyroid Carcinoma (RR-DTC) and advanced/metastatic medullary thyroid carcinoma are relatively uncommon yet prognostically significant thyroid cancers. Gene rearrangements resulting in the aberrant activity of tyrosine kinases have been identified as drivers of oncogenesis in a variety of cancers, including thyroid cancer. Many Multi-Kinase Inhibitors (MKIs) which are now FDA-/EMA approved for thyroid cancer have shown clinical benefit in patients with advanced cancer. Treatment related toxicities occur frequently with these drugs and can be severe or life-threatening. </P><P> Objectives: This review summarizes the role of targeted therapy with MKIs in the management of RRDTC and advanced/metastatic MTC patients, focusing on side-effect profiles of these drugs, with a presentation of several recent patents published in this field. </P><P> Methods: We review the scientific literature on advanced thyroid cancer and analyze the International Pharmacovigilance database (FAERS, Eudravigilance, and WHO Vigibase) for adverse drug reactions. </P><P> Results: This systematic analysis highlights the difference in the safety profile of the recent drugs used in the treatment of advanced thyroid cancer and the recent discoveries for diagnosis or treatment of the thyroid cancer. </P><P> Conclusion: It is essential to investigate the safety profile of recent anticancer drugs for advanced thyroid cancer to allow health professionals to make the best choice for each patient by conducting risk/benefit assessment.</P>]]></description> </item><item><title><![CDATA[Immunosuppression and Immunotargeted Therapy in Acute Myeloid Leukemia - The Potential Use of Checkpoint Inhibitors in Combination with Other Treatments]]></title><link>https://www.benthamscience.comarticle/97514</link><description><![CDATA[Introduction: Immunotherapy by using checkpoint inhibitors is now tried in the treatment of several malignancies, including Acute Myeloid Leukemia (AML). The treatment is tried both as monotherapy and as a part of combined therapy. <p></p> Methods: Relevant publications were identified through literature searches in the PubMed database. We searched for (i) original articles describing the results from clinical studies of checkpoint inhibition; (ii) published articles describing the immunocompromised status of AML patients; and (iii) published studies of antileukemic immune reactivity and immunotherapy in AML. <p></p> Results: Studies of monotherapy suggest that checkpoint inhibition has a modest antileukemic effect and complete hematological remissions are uncommon, whereas combination with conventional chemotherapy increases the antileukemic efficiency with acceptable toxicity. The experience with a combination of different checkpoint inhibitors is limited. Thalidomide derivatives are referred to as immunomodulatory drugs and seem to reverse leukemia-induced immunosuppression, but in addition, they have direct inhibitory effects on the AML cells. The combination of checkpoint targeting and thalidomide derivatives thus represents a strategy for dual immunotargeting together with a direct antileukemic effect. <p></p> Conclusion: Checkpoint inhibitors are now tried in AML. Experimental studies suggest that these inhibitors should be combined with immunomodulatory agents (i.e. thalidomide derivatives) and/or new targeted or conventional antileukemic treatment. Such combinations would allow dual immunotargeting (checkpoint inhibitor, immunomodulatory agents) together with a double/triple direct targeting of the leukemic cells.]]></description> </item><item><title><![CDATA[Mouse Models of Familial Hemiplegic Migraine for Studying Migraine Pathophysiology]]></title><link>https://www.benthamscience.comarticle/98451</link><description><![CDATA[Migraine, an extremely disabling neurological disorder, has a strong genetic component. Since monogenic migraines (resulting from mutations or changes in a single gene) may help researchers discover migraine pathophysiology, transgenic mice models harboring gene mutations identified in Familial Hemiplegic Migraine (FHM) patients have been generated. Studies in these FHM mutant mice models have shed light on the mechanisms of migraine and may aid in the identification of novel targets for treatment. More specifically, the studies shed light on how gene mutations, hormones, and other factors impact the pathophysiology of migraine. The models may also be of relevance to researchers outside the field of migraine as some of their aspects are relevant to pain in general. Additionally, because of the comorbidities associated with migraine, they share similarities with the mutant mouse models of epilepsy, stroke, and perhaps depression. Here, we review the experimental data obtained from these mutant mice and focus on how they can be used to investigate the pathophysiology of migraine, including synaptic plasticity, neuroinflammation, metabolite alterations, and molecular and behavioral mechanisms of pain.]]></description> </item><item><title><![CDATA[Clinical Implications of Methotrexate Pharmacogenetics in Childhood Acute Lymphoblastic Leukaemia]]></title><link>https://www.benthamscience.comarticle/96230</link><description><![CDATA[<P>Background: In the past two decades, a great body of research has been published regarding the effects of genetic polymorphisms on methotrexate (MTX)-induced toxicity and efficacy. Of particular interest is the role of this compound in childhood acute lymphoblastic leukaemia (ALL), where it is a pivotal drug in the different treatment protocols, both at low and high doses.

Here, we aim to identify the potential viral pathogens leading to aberrant inflammatory and oxidative stress response in AD along with potential drug candidates using systems biology approach. We retrieved protein interactions of amyloid precursor protein (APP) and tau protein (MAPT) from NCBI and genes for oxidative stress from NetAge, for inflammation from NetAge and InnateDB databases. Genes implicated in aging were retrieved from GenAge database and two GEO expression datasets. These genes were individually used to create protein-protein interaction network using STRING database (score&#8805;0.7). The interactions of candidate genes with known viruses were mapped using virhostnet v2.0 database. Drug molecules targeting candidate genes were retrieved using the Drug- Gene Interaction Database (DGIdb). Data mining resulted in 2095 APP, 116 MAPT, 214 oxidative stress, 1269 inflammatory genes. After STRING PPIN analysis, 404 APP, 109 MAPT, 204 oxidative stress and 1014 inflammation related high confidence proteins were identified. The overlap among all datasets yielded eight common markers (AKT1, GSK3B, APP, APOE, EGFR, PIN1, CASP8 and SNCA). These genes showed association with hepatitis C virus (HCV), Epstein– Barr virus (EBV), human herpes virus 8 and Human papillomavirus (HPV). Further, screening of drugs targeting candidate genes, and possessing anti-inflammatory property, antiviral activity along with a suggested role in AD pathophysiology yielded 12 potential drug candidates. Our study demonstrated the role of viral etiology in AD pathogenesis by elucidating interaction of oxidative stress and inflammation causing candidate genes with common viruses along with the identification of potential AD drug candidates.]]></description> </item><item><title><![CDATA[Carbon Nano-onions: A Valuable Class of Carbon Nanomaterials in Biomedicine]]></title><link>https://www.benthamscience.comarticle/94775</link><description><![CDATA[The development of nanoscale materials is an important area of research as it provides access to materials with unique properties that can be applied to improve quality of life.

This review highlights the detailed Pharmacokinetics (PK) and Pharmacodynamics (PD) information of NAT, with the Pharmacogenomics (PG) properties of NAT. </P><P> Methods: We undertake a systemic English-language search of Medline, EMBASE, Cochrane Library electronic databases to identify all potential studies with PK, PD or PG properties of NAT (up to October 2017). </P><P> Results: Five papers contain detailed pharmacokinetic parameters are included in this review. Body weight is the most important factor associated with NAT concentration. Greater PK similarity and PD comparability is observed following Subcutaneous (SC) administration than Intramuscular (IM) administration. Initial difference in PK measures was observed between SC and Intravenous (IV) administration. However, trough NAT serum concentrations are similar between SC and IV administration after repeated dosing. Antibodies against NAT result in a low serum NAT concentration and cause a loss of efficacy of NAT. Gln-152, Lys-201, and Lys-256 are the three important point mutation on the &#945;4 residues that NAT binds to. Syndecan-1 gene is a potential candidate gene for personalized approach for NAT use in MS. </P><P> Conclusion: As MS is a disease that affects young women most and NAT can pass placental barrier before delivery and into breast milk, a proper risk-benefit analysis of NAT therapy in lactating women are still needed. The relationship between Single Nucleotide Polymorphisms (SNPs) and NAT treatment are still not clear.]]></description> </item><item><title><![CDATA[HELLP Syndrome: Pathophysiology and Current Therapies]]></title><link>https://www.benthamscience.comarticle/91660</link><description><![CDATA[HELLP syndrome is a disorder associated with serious maternal morbidity and mortality. Distinguishing HELLP from other pregnancy-related disorders is often challenging and may result in delay of treatment. Differential diagnoses include acute fatty liver of pregnancy, thrombotic thrombocytopenic purpura, antiphospholipid syndrome, and hemolytic uremic syndrome, and are reviewed in this chapter. While there is not any current treatment for HELLP, the mainstay of treatment involves maternal stabilization and timely delivery. Various treatment strategies have been attempted to help decrease the morbidity and mortality of HELLP, including the maternal use of corticosteroids. The authors review the studies and controversies surrounding the maternal use of corticosteroids, plasma exchange, and low molecular weight heparin for the treatment of HELLP, as well as the role of the complement system in HELLP. Further large, well-designed, randomized controlled trials are needed to address the role corticosteroids may play in the treatment of women with HELLP and to help improve maternal and fetal outcomes.]]></description> </item><item><title><![CDATA[New Life to an Old Treatment: Pegylated Interferon Beta 1a in the Management of Multiple Sclerosis]]></title><link>https://www.benthamscience.comarticle/88791</link><description><![CDATA[Background: In the 1990s, the beta interferons and glatiramer acetate were introduced for treating relapsing-remitting multiple sclerosis. These medications have a demonstrated record of efficacy and safety, although they require frequent administration via injection and are only partially effective. The optimization of treatment in patients who do not respond adequately to this first-line therapy is essential for attaining the best long-term outcomes. Switching to the recently approved emergent therapies is a strategy to consider for treatment of patients with a suboptimal response. </P><P> Objective: This review summarizes the mechanisms of action, clinical benefits, and safety profiles of current multiple sclerosis disease-modifying therapies, including highly efficacious monoclonal antibodies or convenient oral therapies, and with a special focus on the pegylated interferon beta 1a formulation. </P><P> Methods: We reviewed the recent literature and human clinical trials on multiple sclerosis therapies by bibliographic search in PubMed and clinicaltrials.gov. </P><P> Results and Conclusion: Although the first-line interferon beta exhibits a favorable benefit-torisk profile, treatment compliance is compromised potentially due to its known adverse events and frequent injectable administration. Less frequent dosing and improved pharmacological properties have been achieved by reaction of interferon beta with chemically activated polyethylene glycol. Provided that none of the available therapies show better effectiveness for all outcomes and their safety in clinical practice is of a fundamental concern, the pegylated form of interferon beta seems to keep its place as a competitive therapeutic option.]]></description> </item><item><title><![CDATA[Neuroimaging Features of Acquired Metabolic and Toxic Encephalopathies]]></title><link>https://www.benthamscience.comarticle/83198</link><description><![CDATA[Background: Toxic and metabolic encephalopathies are easily misinterpreted or overlooked in daily neuroimaging practices. </P><P> Aims: This review aims to summarize the imaging features of a number of acquired metabolic and toxic encephalopathies. </P><P> Discussion: These conditions are not diagnosed easily. Imaging is very important in terms of diagnosis, assessment of treatment response and prediction of prognosis.

The aim of the present study is to test the modulatory effect of sinapic acid against toluene induced dementia of LEP type in rats. </P><P> Materials and Methods: The study was designed to induce dementia by inhalation of toluene vapours (0.7% in air for 15 min.) for a period of 14 days in rats and then divided among different groups, i.e. Treatment group, negative control and two groups of sinapic acid, (at a dose of 20 and 40mg/kg, p.o.). These groups were treated and observed until the 28th day of experimental trial. The avoidance/escape behaviour was measured via Pole Climbing Apparatus; spatial memory was measured via Morris Water Maze, and locomotion was measured via photoactometer (beam breaks). The behavioral, Neuronal and biochemical parameters were determined. The estimation of Monoamine Oxidase (MAO-A, MAO-B), TNF-&#945;, Acetylcholine esterase Enzyme and various antioxidant enzymes (GSH, TBARS, Nitrite, Catalase) was done by methods available in literature. Histological changes in the brain were also observed. </P><P> Result: Rats receiving 40 mg/kg of sinapic acid showed a significant therapeutic activity against toluene induced dementia of LEP type in rats. </P><P> Conclusion: From the present experimental findings, it has been concluded that a dose of 40 mg/kg, (p.o.) of sinapic acid provides better neuromodulation in neurons against toluene induced dementia of LEP type in rats with a better choice of drug.]]></description> </item><item><title><![CDATA[Present Drug Therapy of Demyelinating Disorders]]></title><link>https://www.benthamscience.comarticle/85160</link><description><![CDATA[Background: Multiple sclerosis (MS) is an immune-mediated inflammatory disease that attacks myelinated axons in the central nervous system, destroying the myelin and the axon in variable degrees and causing significant disability in many patients. Neuro-Myelitis Optica Spectrum Disorder (NMOSD) is a rare disorder that was considered a subtype of MS but is now recognized as a distinct demyelinating disorder that affects mainly the spine and optic nerves. </P><P> Objective: The present paper is a review of the recent knowledge regarding present and new drugs that have been recently added to the therapeutic arsenal for MS as well as those which seem to be beneficial for patients with NMOSD. </P><P> Methods: A step-by-step description of the evolving drug arsenal is presented for both MS and Neuro-Myelitis Optica Spectrum Disorder (NMOSD). </P><P> Results: Modern drug therapy for MS started with the introduction of ACTH (Adrenocorticotropic hormone) and somewhat later was followed by high dose corticosteroids for treatment of the neurological deficits during an acute relapse. This mode of treatment, which became popular during the years 1970-1980 failed to reduce the number of relapses or to affect the outcome of the disease. Only during the last two decades, the field of MS drug therapy underwent a remarkable change from simple amelioration of symptoms of an acute attack to the development of numerous Disease Modifying Treatments (DMTs). The formulation of DMTs evolved from the older inconvenient subcutaneous or intramuscular route of administration to oral preparations or periodic intravenous infusions of biological drugs. A new treatment was approved in 2017 for reducing disease progression rate for the first time in primary progressive MS. </P><P> Besides MS, progress was made in delineating the pathophysiology of NMOSD, a devastating demyelinating disorder that is still frequently confused with MS. </P><P> Although beneficial, the new treatment modalities carry with them adverse effects that may be serious and even life threatening. With the increase in the usage of those drugs, the spectrum of the reported adverse effects is expanding and calls for additional research in regard to the safest way of their utilization. </P><P> Conclusion: Targeting the immune system in general in RRMS and NMOSD and even PPMS has proven successful, with efficacy varying based on the specific treatment. There are still unmet needs for medications that will address safety and efficacy altogether and prevent disability even more. </P><P> Areas Covered: The mode of action and main characteristics and side effects of current DMTs for both MS and NMOSD and their place in the therapeutic algorithm of both diseases based on updated evidence from clinical trials.]]></description> </item><item><title><![CDATA[Conjugates of Cell Adhesion Peptides for Therapeutics and Diagnostics Against Cancer and Autoimmune Diseases]]></title><link>https://www.benthamscience.comarticle/88037</link><description><![CDATA[Overexpressed cell-surface receptors are hallmarks of many disease states and are often used as markers for targeting diseased cells over healthy counterparts. Cell adhesion peptides, which are often derived from interacting regions of these receptor-ligand proteins, mimic surfaces of intact proteins and, thus, have been studied as targeting agents for various payloads to certain cell targets for cancers and autoimmune diseases. Because many cytotoxic agents in the free form are often harmful to healthy cells, the use of cell adhesion peptides in targeting their delivery to diseased cells has been studied to potentially reduce required effective doses and associated harmful side-effects. In this review, multiple cell adhesion peptides from extracellular matrix and ICAM proteins were used to selectively direct drug payloads, signal-inhibitor peptides, and diagnostic molecules, to diseased cells over normal counterparts. RGD constructs have been used to improve the selectivity and efficacy of diagnostic and drug-peptide conjugates against cancer cells. From this precedent, novel conjugates of antigenic and cell adhesion peptides, called Bifunctional Peptide Inhibitors (BPIs), have been designed to selectively regulate immune cells and suppress harmful inflammatory responses in autoimmune diseases. Similar peptide conjugations with imaging agents have delivered promising diagnostic methods in animal models of rheumatoid arthritis. BPIs have also been shown to generate immune tolerance and suppress autoimmune diseases in animal models of type-1 diabetes, rheumatoid arthritis, and multiple sclerosis. Collectively, these studies show the potential of cell adhesion peptides in improving the delivery of drugs and diagnostic agents to diseased cells in clinical settings.]]></description> </item><item><title><![CDATA[Therapeutic Monoclonal Antibodies and Multiple Sclerosis: The Essentials]]></title><link>https://www.benthamscience.comarticle/85590</link><description><![CDATA[Background: Monoclonal antibodies (mAbs) are now established as targeted therapies for malignancies, transplant rejection, autoimmune and infectious diseases. Two monoclonal antibodies are available for treatment and other antibodies are currently being tested in multiple sclerosis (MS) patients. </P><P> Objectives: The purpose of the present review paper is to outline the antibody engineering technologies, the immunologic and pharmacologic concepts of mbs and the current status of treatment in MS with emphasis on clinical efficacy and safety. </P><P> Method: We conducted a through review of the scientific literature published until 31 December 2014 (print and electronic publications) concerning the production, applications and side effects of the use of Mabs. Sixty five articles were used in total (both original research and review papers). </P><P> Conclusion: With the introduction of mAbs the treatment of MS has entered a new era, both with respect to efficacy and target specificity. However, administration of mAbs carries the risk of immune reactions such as acute anaphylaxis, serum sickness, infection and other autoimmune diseases. In addition, unexpected consequences arise from our incomplete knowledge of the immune system. For example, natalizumab, a monoclonal antibody targeting &#945;4-integrin on leukocytes increases the risk of developing progressive multifocal leukoencephalopathy, without causing notable immunosuppression. Further study on the use of mabs is required, both in vitro and in the clinical field, in order to increase our knowledge upon these new revolutionary therapeutic agents.]]></description> </item><item><title><![CDATA[The Beneficial Effects of Sulfur-containing Amino Acids on Cisplatininduced Cardiotoxicity and Neurotoxicity in Rodents]]></title><link>https://www.benthamscience.comarticle/84514</link><description><![CDATA[Background: Cisplatin is one the most frequently used chemotherapeutic drugs for several decades. Although its antineoplastic effect has been reported in treatment of numerous malignances, various adverse effects seem to be the crucial limiting factor for its administration. </P><P> Objective: Beside the most commonly described nephro- and hepatotoxicity, cisplatin therapy is also accompanied with gastrointestinal, reproductive, hematological, cardiovascular and neurological side effects. Since it has been reported that cisplatin induce oxidative damage in various tissues, it seems reasonable to investigate an antioxidant supplementation as potential therapeutical approach for attenuation of cisplatin toxicities. </P><P> Methods: We performed a structured search of bibliographic databases for research literature using a focused review question and inclusion/exclusion criteria. The quality of retrieved papers (101 in total) was appraised using standard tools. </P><P> Results: Numerous antioxidants (such as thiol compounds, polyphenols, vitamins, etc.) had been reported for their beneficial effects on cisplatin-induced cardiotoxicity. The effects of various antioxidants, including sulfur-containing amino acids, have also been explored for mitigation of cisplatin neurotoxicity. However, the results for antioxidant supplementation in reduction of cisplatin-induced toxicities are still to be applied in clinical trials. </P><P> Conclusion: Considering the facts that sulfur-containing amino acids: (a) do not interfere with chemotherapeutics antitumor action; (b) do not exhibit any toxic effect (unless applied in dose several times above the recommended); and (c) produce significant protective effects on some cisplatin-induced toxicities connected to augmentation of oxidative damage - it seems that their administration can be harmless and protective supplementation against numerous adverse effects of certain antineoplastic agents.]]></description> </item><item><title><![CDATA[Natalizumab Changes the Peripheral Profile of the Th17 Panel in MS Patients: New Mechanisms of Action]]></title><link>https://www.benthamscience.comarticle/85148</link><description><![CDATA[Introduction: Natalizumab (NAT) is an effective treatment for relapsing remitting multiple sclerosis (RRMS), as it makes the blood-brain-barrier impenetrable by binding to the &#945;4integrin subunit. The objectives of our study were to find new peripheral mechanisms of action of NAT and new biomarkers of treatment response. </P><P> Material and Methods: We prospectively assessed the serum levels of 15 cytokines from the Th17 Cytokine Panel using Bio-plex Pro Human in a group of 29 RRMS patients treated with NAT and 29 healthy subjects (HS) at inclusion and after 8 months of NAT treatment. For each patient, demographic data, number of relapses and Expanded Disability Status Scale (EDSS) were collected and compared with the initial and final values of each cytokine. Moreover, the Th17/Treg shift was assessed using the interleukine (IL)-17F/IL-10 ratio and the cytokine signature (the sum of all the cytokines). Advanced statistical analysis was used. </P><P> Results: RRMS patients had significantly lower serum levels of IL-23, IL-17F, IL-1&#946; and IL-31 compared to HS. Serum sCD40L, IL-17F, IL-31 and cytokine signature levels significantly decreased after 8 months of NAT treatment. Positively correlations were found between the relapse number and IL- 17F, IL-1&#946;, IL-31 serum levels and between EDSS and tumor necrotic factor-&#945;, IL-1&#946; and IL-17/IL-10 serum levels. IL-10 serum levels correlated negatively with the EDSS score. </P><P> Conclusion: In evaluating the mode of action of NAT, it is important to determine the value of each cytokine, the Th17/Treg shift and the cytokine signature. NAT significantly decreased peripheral serum levels of some pro-inflammatory cytokines as a novel mechanism of action. IL-17F, sCD40L and IL-31 were the best biomarkers to assess the effectiveness of NAT.]]></description> </item><item><title><![CDATA[Pediatric Cutaneous Graft Versus Host Disease: A Review]]></title><link>https://www.benthamscience.comarticle/84107</link><description><![CDATA[Background: Graft versus host disease (GVHD) is a significant complication following hematopoietic stem cell transplantation in the pediatric population. The most common clinical manifestation of GVHD is in the skin. This article will present a review of key concepts related to pediatric cutaneous GVHD, including pathophysiology, clinical epidemiology, diagnosis, and treatment options. </P><P> Objective: GVHD is an immune-mediated process characterized by an inflammatory immune response in acute GVHD and mixed inflammatory and fibrotic states in chronic GVHD. The clinical presentations of cutaneous GVHD are heterogeneous. Method: Acute cutaneous GVHD classically presents as an erythematous morbilliform eruption appearing within a few weeks after transplantation. Chronic cutaneous GVHD may manifest as poikiloderma, lichenoid lesions, or sclerodermatous changes. The sclerodermatous form of cutaneous GVHD is associated with substantial long-term morbidity, including joint contractures, myalgias, and mobility restriction. </P><P> Results: First-line pharmacologic treatment options typically include corticosteroids and in some cases, calcineurin inhibitors. Biologics and immunotherapies are an active area of investigation for GVHD that is refractory to corticosteroid treatment. Non-pharmacologic treatment options that have shown benefit for cutaneous GVHD include extracorporeal photopheresis and phototherapy. </P><P> Conclusion: Accurate diagnosis and treatment of cutaneous GVHD is essential to preventing and alleviating the long-term sequelae and morbidity associated with this condition.]]></description> </item><item><title><![CDATA[Dermatological, Cardiovascular and Neurological Morphohistopathological Effects of Fluoropyrimidine-based Chemotherapy in Humans]]></title><link>https://www.benthamscience.comarticle/86821</link><description><![CDATA[Background: Fluoropyrimidines are anticancer drugs used for the treatment of solid tumours. Apart from general side effects common to other anticancer drugs, the intravenously administered 5-fluorouracil (5-FU) and the recently developed oral prodrugs can induce toxicity at cardiovascular, neurologic and dermatologic level, which is reversed by treatment interruption, discontinuation, dose reduction and supportive therapies. </P><P> Objective: To examine, from the morphohistopathological point of view, the main toxic effects induced by fluoropyrimidines. </P><P> Methods: Pertinent articles were retrieved through PubMed search. </P><P> Results: Unlike dermatologic toxicity, with evident histopathological observations because of the easy approach to skin examination, cardio- and neurotoxicity are scarcely documented, with most imaging and functional data poorly altered. Animal models are useful to corroborate data obtained in humans. Fluoropyrimidines can associate with specific cutaneous side effects, including the hand-foot syndrome (HFS), with symmetrical erythema, dysaesthesia, dryness, rash, swelling and desquamation on palms and soles. Cardiotoxicity includes angina pectoris, arrhythmias, palpitation, hypotension, hypertension, malaise and dyspnea, until life-threatening damages, with myocardial infarction and sudden death. Neurotoxicity is an uncommon but potentially severe side effect, consisting of rare cases of cerebellar alterations with ataxia, as well as multifocal cerebral leukoencephalopathy, with or without seizures, announcing with dizziness, memory deficits, trismus, headache, vertigo, gait disturbances and confusion, until coma. These adverse events are likely due to direct chemotoxic effects of fluoropyrimidine metabolites and most of them can be regarded as allergic reactions triggered by the hapten-like properties of these molecules. </P><P> Conclusion: Fluoropyrimidines are able to induce specific morphohistopathological changes in tissues.]]></description> </item><item><title><![CDATA[Chemistry in the Bioactivity of Chlorophylls: An Overview]]></title><link>https://www.benthamscience.comarticle/84773</link><description><![CDATA[Background: In addition to the considerable number of different chlorophyll structures originated naturally, prominent research is made to produce new specific semisynthetic structures.

Thus, anti-angiogenic agents have been developed and are mainly vascular endothelial growth factor (VEGF) pathway inhibitors. However, these agents commonly exhibit cardiac and renal toxicity, proteinuria and hypertension (HT). In fact, with the use of anti-angiogenic agents a rapid dose-dependent increase of blood pressure (BP) is observed. The possible mechanisms of VEGF inhibitors-induced HT include systemic endothelial dysfunction, renal impairment as well as vascular micro- and macroangiopathy. Furthermore, the simultaneous use of non-steroidal anti-inflammatory drugs (NSAIDs) and opioids in these patients results in uncontrolled HT. </P><P> Conclusion: Lifestyle changes are the cornerstone of antihypertensive treatment. No clear recommendations for a specific antihypertensive agent can be made. In most cases antihypertensive management needs to be individualized to each patient. Calcium channel blockers (CCBs) are considered as first line option, while renin-angiotensin-aldosterone system (RAAS) blockers should be the agents of choice in patients with proteinuria. Centrally acting antihypertensive agents and diuretics can also be used. Careful monitoring is critical during therapy and BP should be assessed every week and before any new cycle or infusion of anti-VEGF therapy. If BP remains uncontrolled anti-VEGF treatment discontinuation should be considered. Withdrawal of anti-VEGF therapy needs also a re-evaluation of antihypertensive therapy since BP will return to the prior baseline levels.]]></description> </item><item><title><![CDATA[Current and Under Development Treatment Modalities of Psoriasis: A Review]]></title><link>https://www.benthamscience.comarticle/85133</link><description><![CDATA[Background and Objective: Psoriasis is a chronic and complex autoimmune inflammatory skin disease that affects over 125 million people worldwide. It can exhibit at any age, in spite of the fact that children are less normally influenced than adults. It is characterized by distinct erythematous plaques shielded with conspicuous silvery scales that shows up in different areas of the skin. Knowledge of pathophysiology, especially the pathogenesis of psoriasis, has significantly progressed in the recent decade. Advancement in molecular knowledge leads to better understanding of the disease, thus influencing the development of efficient treatment modalities. However, even with the availability of various options of treatment most of the efficient treatment modalities are costly. Expenses of health care bring about major financial weight to the patients as well as to health care systems. Thus, it was important to review the available current treatment options and those which are under development, in terms of efficacy, safety and cost to assist in selecting the most appropriate treatment for psoriasis patients. </P><P> Methods: Literatures were searched by using key words psoriasis, topical treatment, systemic treatment, biologics and phototherapies, on Embase, Medline, Jstor, Cochrane and Merck Index databases. </P><P> Results: Life-style choices such as smoking, alcohol consumption, obesity and stress are recognised as risk factors and triggers associated with psoriasis. Psoriasis poses psycho-social and economic burden on affected patients that sometimes leads to depression, reduced social interaction and suicidal tendencies in patients. Depending on the type, severity and extent of the disease, comorbidities, patient preference, efficacy and safety profile, numerous treatment modalities and therapeutic agents are available such as topical, systemic, biologic and phototherapeutic treatments. However, it was found that among all the current available treatments for psoriasis, biologic agents and phototherapeutic modalities are the most commonly employed treatment modalities for moderate to severe psoriasis. </P><P> Conclusion: Evaluation of present-day available treatment alternatives will surely help physician to select a suitable module for each patient while keeping in mind the financial status of the patient. Future research should aim to develop therapies which are efficient, safe and cost-effective.]]></description> </item><item><title><![CDATA[Role of microRNAs on Blood Brain Barrier Dysfunction in Vascular Cognitive Impairment]]></title><link>https://www.benthamscience.comarticle/78063</link><description><![CDATA[Background: Dementia cases are increasing as the population ages, leading to increased financial costs. Several neuronal diseases including ischemic and hemorrhagic stroke involve cerebrovascular injury or pathophysiology. Cerebrovascular injury is closely tied to blood brain barrier (BBB) disruption. Many studies have shown a significant association between BBB dysfunction and neurological diseases. Therefore, an understanding of the molecular mechanisms which regulate BBB permeability and disruption is essential for establishing future therapeutic strategies to alter dementia disease progression related to cerebrovascular injury, so-called vascular cognitive impairment (VCI). microRNAs (miRs) are small non-coding RNAs that regulate gene expression through targeting of mRNA transcripts. miRs have been implicated in the development and progression of various illnesses, including vascular disease. However, the role of miRs in BBB breakdown or permeability and VCI development has not yet been well clarified. <P></P> Method: Research content related to the origins of VCI and the role of the BBB in pathologic development and therapeutic targeting are reviewed, including current relevant animal models. We draw from the published literature regarding microRNA candidates that are associated with modulation of BBB structure and function. <P></P> Results: In this review, we summarize the current knowledge about VCI, explore the potential role of miRs in BBB breakdown and VCI progression, and identify potential candidate miRs for development of new treatment strategies. <P></P> Conclusion: miRs constitute a promising novel avenue as future therapeutic options for alteration of both BBB permeability and development of VCI.]]></description> </item><item><title><![CDATA[Pericyte: Potential Target for Hemorrhagic Stroke Prevention and Treatment]]></title><link>https://www.benthamscience.comarticle/78034</link><description><![CDATA[Background: Despite long-standing and worldwide efforts, hemorrhagic stroke remains a critical clinical syndrome that exerts a heavy toll on affected individuals and their families due to the lack of preventive and therapeutic targets. <P></P> Objective: To clarify the pathogenesis of hemorrhagic stroke and to identify novel therapeutic targets. <P></P> Method: Targeting pericytes, the typical mural cells of microvessels, could serve as a way to modulate microvascular permeability, development, and maturation by regulating endothelial cell functions and modulating tissue fibrosis and inflammatory responses. <P></P> Results: Pericytes in hemorrhagic stroke may exert the following functions: before bleeding, the morphological aberration and dysfunction of pericytes may lead to aneurysm formation, angiopsathyrosis, and hemodynamic disturbances, ultimately causing vasculature rupture. In the acute phase after hemorrhage, pericytes are faced with a complicated bleeding environment, which results in the death of pericytes, blood-brain barrier damage, pericyte-mediated inflammatory cascades, white matter impairment, and ultimately aggravated neural injury. In the recovery period post-hemorrhage, in situ pericytes are activated and differentiate into neurons, glia and endothelial cells to repair the neural vascular network. Moreover, many pericytes are recruited to the lesion and contribute to blood-brain barrier remodeling, thus facilitating neurovascular functional recovery after stroke. <P></P> Conclusion: Due to the multiple functions of pericytes in the development of vascular rupture and hemorrhagic stroke pathophysiology, additional drugs and trials targeting pericytes and evaluations of their effectiveness are required in future investigations to develop new strategies for the prevention and treatment of hemorrhagic stroke.]]></description> </item><item><title><![CDATA[White Matter Integrity in Subcortical Vascular Cognitive Impairment: A Multimodal Structural MRI Study]]></title><link>https://www.benthamscience.comarticle/82535</link><description><![CDATA[Objective: To investigate the disruption of white matter (WM) integrity in patients with subcortical vascular cognitive impairment (SVCI) with multimodal structural magnetic resonance imaging (MRI), and to explore the relationships between WM damage, structural network disruptions, and general cognitive function decline. <P></P> Methods: Twenty-eight patients with SVCI and twenty control subjects underwent structural MRI scans and neuropsychological assessment. WM volume (WMV), WM hyperintensities (WMH), lacunar infarcts (LI), diffusion tensor imaging parameters and structural network characteristics were compared between two groups. Correlations between these parameters and general cognitive function were calculated. <P></P> Results: WMV, WMH load, LI number, mean fractional anisotropy (FA), peak height and peak location of mean diffusivity (MD) of normal-appearing WM (NAWM) and structural network characteristics were significantly different between the two groups. Disruption of WM microstructure and network characteristics was widespread. WMV, WMH load, mean FA and peak location of MD of NAWM explained about 70% of the variance in structural network characteristics. Shortest path length with LI number explained 47.5% of the variance in z-scores. <P></P> Conclusion: SVCI was associated with widespread disruptions of WM integrity in the brain. Network characteristics may be a comprehensive reflection of WM integrity and a superior predictor of general cognitive function, while LI was an independent predictor of cognitive impairment.]]></description> </item><item><title><![CDATA[From Leflunomide to Teriflunomide: Drug Development and Immunosuppressive Oral Drugs in the Treatment of Multiple Sclerosis]]></title><link>https://www.benthamscience.comarticle/80240</link><description><![CDATA[Background: Immunosuppressive drugs have been used in the treatment of multiple sclerosis (MS) for a long time. Today, orally available second generation immunosuppressive agents have been approved or are filed for licensing as MS therapeutics. Due to semi-selective targeting of cellular processes, these second-generation immunosuppressive compounds might rather be immunomodulatory. For example, Teriflunomide inhibits the de novo pyrimidine synthesis and thus only targets rapidly proliferating cells, including lymphocytes. It is used as first line disease modifying therapy (DMT) in relapsing-remitting MS (RRMS). <P></P> Methods: Review of online content related to oral immunosuppressants in MS with an emphasis on Teriflunomide. <P></P> Results: Teriflunomide and Cladribine are second-generation immunosuppressants that are efficient in the treatment of MS patients. For Teriflunomide, a daily dose of 14 mg reduces the annualized relapse rate (ARR) by more than 30% and disability progression by 30% compared to placebo. Cladribine reduces the ARR by about 50% compared to placebo but has not yet been licensed due to unresolved safety concerns. We also discuss the significance of older immunosuppressive compounds including Azathioprine, Mycophenolate mofetile, and Cyclophosphamide in current MS therapy. <P></P> Conclusion: Teriflunomide has shown a favorable safety and efficacy profile in RRMS and is a therapeutic option for a distinct group of adult patients with RRMS.]]></description> </item><item><title><![CDATA[Gender and Pathology-Specific Effect of Apolipoprotein E Genotype on Psychosis in Alzheimer’s Disease]]></title><link>https://www.benthamscience.comarticle/81861</link><description><![CDATA[Background: Symptoms of psychosis is one of the common clinical manifestations of Alzheimer’s disease (AD). However, the pathophysiology behind psychosis is unknown. <p></p> Objective: The aim of the present study was to explore the relationship between Apolipoprotein E (APOE) genotype, Lewy body pathology, and psychosis in AD. <p></p> Method: The data was obtained from the National Alzheimer’s disease Coordinating Centre (NACC), using the Uniform Data Set and the Neuropathology Data Set. Subjects with frequent neuritic plaque on CERAD, and Braak Stage of V or VI, corresponding to high probability of AD based on the NIA-AA Regan criteria were included in the analysis. <p></p> Results: Subjects with two copies of ε4 alleles were significantly more likely to develop psychosis, both delusions and/or hallucinations, during the course of their illness. This association was gender-specific, only reaching significance in females. Our findings further showed that presence of two copies of ε4 allele was positively associated with the formation of Lewy bodies. Only in females with Lewy bodies was the effect of two copies of ε4 allele significant, reaching an odd ratio of 4.5. <p></p> Conclusion: The APOE ε4 allele has a female-specific effect in inducing psychosis in AD through the formation of Lewy bodies. <p></p>]]></description> </item><item><title><![CDATA[Safety of Systemic Biologic Agents in the Treatment of Non-malignant Skin Disorders]]></title><link>https://www.benthamscience.comarticle/83536</link><description><![CDATA[Introduction: The recent significant breakthroughs in the understanding of the pathogenetic mechanisms of psoriasis and other immune-mediated inflammatory disorders, have led to the emergence of a wide array of biologic agents or biologics, which are especially designed to target selective intracellular or extracellular components and pathways of the dysregulated immune response. <p></p> Method: These targeted biologic agents have altered the landscape in dermatotherapy aiming to offer higher therapeutic efficacy and an alternative in patients who either failed on conventional systemic regimens or have no other therapeutic options. In the last two decades, the number of the commercially available biologic agents and the extent of their use have dramatically increased; today, these compounds represent a substantial part of modern dermatologic armamentarium. <p></p> Results: Due to the immunosuppressive potential of biologics, serious concerns were raised about their safety profile, already during the pre-approval period. These concerns did not subside after the incorporation of the postmarketing experience, particularly after the withdrawal of a biologic agent (efalizumab) due to its serious and even fatal side effects. <p></p> Conclusion: The purpose of the present article is to review the cutaneous and systemic side effects of all systemic biologic agents used so far in modern treatment of non-malignant skin disorders and to contribute to a better and updated awareness of their safety risks among clinicians, which will enable the latter to make the best informed and personalized drug selection and therapeutic decisions. This review was mainly based on data derived from Medline and Scopus databases and from manufacturing companies, as well. <p></p>]]></description> </item><item><title><![CDATA[Peptides Against Autoimmune Neurodegeneration]]></title><link>https://www.benthamscience.comarticle/83877</link><description><![CDATA[The mammalian immune system is a nearly perfect defensive system polished by a hundred million years of evolution. Unique flexibility and adaptivity have created a virtually impenetrable barrier to numerous exogenous pathogens that are assaulting us every moment. Unfortunately, triggers that remain mostly enigmatic will sometimes persuade the immune system to retarget against self-antigens. This civil war remains underway, showing no mercy and taking no captives, eventually leading to irreversible pathological changes in the human body. Research that has emerged during the last two decades has given us hope that we may have a chance to overcome autoimmune diseases using a variety of techniques to “reset” the immune system. In this report, we summarize recent advances in utilizing short polypeptides - mostly fragments of autoantigens - in the treatment of autoimmune neurodegeneration.]]></description> </item><item><title><![CDATA[Therapeutic Use of Brentuximab Vedotin in CD30+ Hematologic Malignancies]]></title><link>https://www.benthamscience.comarticle/78150</link><description><![CDATA[The CD30 antigen is strongly expressed on neoplastic cells in classical Hodgkin lymphoma (HL), anaplastic large cell lymphoma (ALCL) and other hematologic malignancies (such as DLBCL and cutaneous TCL), while is almost undetectable on healthy tissues, representing an ideal immunotherapeutic target. Since unconjugated anti-CD30 antibody (SGN-30) demonstrated limited clinical activity, researchers’ effort aimed to create an antibody-drug conjugate (ADC), leading to discovery of SGN-35 (brentuximab vedotin), in which an anti-CD30 antibody is linked to the antimitotic agent monomethyl auristatin E (MMAE). In the first phase I study in CD30+ hematologic malignancies (the majority of patients with HL), the maximum tolerated dose was fixed respectively at 1.8mg/Kg every 3 weeks, overall response rate (ORR) and complete response (CR) rate were 38% and 24%. In 2 subsequent phase II studies, amazing results were reported, that permitted accelerated FDA approval for relapsed/refractory patients and led to the development of many clinical trials including BV as first-line HL and ALCL treatment. Moreover, as CD30 antigen may be expressed by other malignancies, the potential therapeutic application is increasing, including at least diffuse large B-cell lymphoma, T-cell lymphomas other than ALCL and cutaneous lymphoproliferative disorders. BV is administrated as outpatient regimen and is usually well tolerated; sensorial peripheral neuropathy represents the most common toxic effect, although it is dose-dependent and at least partially reversible in most cases, after dose reduction and/or treatment ending.]]></description> </item><item><title><![CDATA[Translational Multimodality Neuroimaging]]></title><link>https://www.benthamscience.comarticle/82286</link><description><![CDATA[Background: Recently high-resolution, noninvasive, multimodality in-vivo molecular imaging with PET, SPECT, CT and MRI, employing fusion algorithms has revolutionized personalized medicine. However, novel discovery of specific radiopharmaceuticals (RPs) for the accurate diagnosis and effective treatment of progressive neurodegenerative diseases such as Alzheimer&#039;s disease, Parkinson&#039;s disease, drug addiction, and other cognitive impairments still remains a significant challenge. <P></P> Objective: The primary objective of this review is to highlight the clinical significance of multimodality fusion neuroimaging for the determination of: pharmacokinetics and pre-clinical development of radiopharmaceuticals (RPs); in-vivo monitoring of stem cell transplantation therapy; nicotinic acetylcholine receptors (nAChRs) investigations; and regional cerebral blood flow and glucose metabolism in cognitively-impaired subjects employing multimodality noninvasive PET, CT, MRI/MRS, and SPECT imaging. <P></P> Method: Recent methodology to perform multimodality imaging employing computer-based fusion algorithms is provided with a primary emphasis on nanoSPECT/CT, PET-CT, and PET-MRI in experimental animals. Multimodality imaging is performed to detect CNS infections using 99mTc-HMPAO SPECT and 18F-FDG PET/CT. Furthermore, limitations of individual neuroimaging system, body movements due to cardiorespiratory activity, and co-registration of multimodality neuroimaging data are described. <P></P> Results: Multimodality neuroimaging is clinically-significant because it emphasizes the importance of complementary imaging for theranostic applications and minimizes the inherent limitations of individual neuroimaging approach. However, it may increase the radiation dose to a susceptible pediatric population. <P></P> Conclusion: Future developments in specific RPs with minimum radiation exposure will facilitate early differential diagnosis, prevent, slowdown and/or cure neurodegenerative diseases, cardiovascular diseases, and cancer. Eventually, conventional and functional neuroimaging, combined with clinical, laboratory and - omics analyses will facilitate theranostics to accomplish the ultimate goal of personalized medicine. <P></P>]]></description> </item><item><title><![CDATA[COMMENTARY: Transcranial Magnetic Stimulation in Multiple Sclerosis: A Method to Improve Movement]]></title><link>https://www.benthamscience.comarticle/81096</link><description><![CDATA[]]></description> </item><item><title><![CDATA[The Sphingosine 1-Phosphate Signaling Pathway in Epilepsy: A Possible Role for the Immunomodulator Drug Fingolimod in Epilepsy Treatment]]></title><link>https://www.benthamscience.comarticle/79523</link><description><![CDATA[It is currently known that erythrocytes are the major source of sphingosine 1-phosphate (S1P) in the body. S1P acts both extracellularly as a cellular mediator and intracellularly as an important second messenger molecule. Its effects are mediated by interaction with five specific types of G proteincoupled S1P receptor. Fingolimod, is a recognized modulator of S1P receptors, and is the first orally active disease-modifying therapy that has been approved for the treatment of multiple sclerosis. Magnetic resonance imaging data suggest that fingolimod may be effective in multiple sclerosis by preventing blood-brain barrier disruption and brain atrophy. Fingolimod might also possess S1P receptorindependent effects and exerts both anti-inflammatory and neuroprotective effects. <p></p> In the therapeutic management of epilepsy, there are a great number of antiepileptic drugs, but there is still a need for others that are more effective and safer. S1P and its receptors might represent a suitable novel target also in light of their involvement in neuroinflammation, a well-known process underlying seizures and epileptogenesis. The objective of this manuscript is to review the biological role of S1P and its receptors, focusing on their expression, effects and possible involvement in epilepsy; furthermore, we summarize the possible anti-seizure properties of fingolimod and discuss its possible usefulness in epilepsy treatment. We conclude that fingolimod, being already commercially available, might be easily tested for its possible therapeutic effectiveness in epileptic patients, both after a more comprehensive evaluation of the real potential of this drug and following a clear evaluation of the potential role of its main targets, including the S1P signaling pathway in epilepsy. <p></p>]]></description> </item><item><title><![CDATA[Pharmacological Tools to Activate Microglia and their Possible use to Study Neural Network Patho-physiology]]></title><link>https://www.benthamscience.comarticle/78656</link><description><![CDATA[Background: Microglia are the resident immunocompetent cells of the CNS and also constitute a unique cell type that contributes to neural network homeostasis and function. Understanding microglia cell-signaling not only will reveal their diverse functions but also will help to identify pharmacological and non-pharmacological tools to modulate the activity of these cells. <p></p> Methods: We undertook a search of bibliographic databases for peer-reviewed research literature to identify microglial activators and their cell-specificity. We also looked for their effects on neural network function and dysfunction. <p></p> Results: We identified several pharmacological targets to modulate microglial function, which are more or less specific (with the proper control experiments). We also identified pharmacological targets that would require the development of new potent and specific modulators. We identified a wealth of evidence about the participation of microglia in neural network function and their alterations in pathological conditions. <p></p> Conclusion: The identification of specific microglia-activating signals provides experimental tools to modulate the activity of this heterogeneous cell type in order to evaluate its impact on other components of the nervous system, and it also helps to identify therapeutic approaches to ease some pathological conditions related to microglial dysfunction. <p></p>]]></description> </item><item><title><![CDATA[Targeting Notch as a Therapeutic Approach for Human Malignancies]]></title><link>https://www.benthamscience.comarticle/78807</link><description><![CDATA[Background: Notch is a multifaceted protein that plays a fundamental role in fetal development and tissue homeostasis by directing many cellular functions, including cell growth and differentiation, cell fate determination and regulation of stem cells maintenance. The Notch family consists of four receptors (Notch 1-4) and five ligands (Jagged1-2 and Delta-like 1-3-4) widely expressed in human tissues. Given the crucial contribution of Notch signaling in many physiological processes, it is not surprising that a variety of human malignancies is characterized by a dysregulation of one or more components of this pathway. <p></p> Methods: In this review, we are going to provide a broad overview on the role of Notch pathway in solid and hematological malignancies and a survey on possible Notch-directed therapeutic strategies. <p></p> Results: We present the most recent findings indicating that Notch signaling dysregulation in human cancers may be due to genetic and epigenetic alterations or to the interactions with other oncogenic pathways. Furthermore, Notch activity may have an oncogenic or a tumor suppressor effect. Finally, we describe the latest preclinical and clinical studies concerning the different pharmacological approaches targeting Notch. <p></p> Conclusion: The provided evidence confirms the importance of Notch pathway in human malignancies indicating that a strong rationale exists for the development of a Notch-tailored therapy. <p></p>]]></description> </item><item><title><![CDATA[SUMOylation in Neurological Diseases]]></title><link>https://www.benthamscience.comarticle/80900</link><description><![CDATA[Since the discovery of SUMOs (small ubiquitin-like modifiers) over 20 years ago, sumoylation has recently emerged as an important posttranslational modification involved in almost all aspects of cellular physiology.

Thus, the dysfunction of sumoylation pathway is associated with many different neurological disorders. Hundreds of different proteins implicated in the pathogenesis of neurological disorders are SUMO-modified, indicating the importance of sumoylation involved in the neurological diseases.

Current intensive cytotoxic therapies can be associated with significant morbidity and novel therapies are needed to improve outcomes. Immunotherapy based approaches provide an alternative mechanism of action in the treatment of acute leukemia. Due to cell surface antigen expression, leukemia in particular is amenable to targeted therapies, such as antibody-based therapy. Based on the potential for non-overlapping toxicity, the possibility of synergistic action with standard chemotherapy, and by providing a novel method to overcome chemotherapy resistance, antibody-based therapies have shown potential for benefit. Modifications to standard monoclonal antibodies, including drug conjugation and linkage to T-cells, may further enhance efficacy of antibody-based therapies. Identifying the ideal timing for incorporation of antibody-based therapies, within standard regimens, may lead to improvement in overall outcomes. This article will provide an overview of antibody-based therapies in clinical development for the treatment of acute leukemia in children and adults, with a particular focus on the current strategies and future developments.]]></description> </item><item><title><![CDATA[Novel Mutation of the NOTCH3 Gene in a Chinese Pedigree with CADASIL]]></title><link>https://www.benthamscience.comarticle/79188</link><description><![CDATA[Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) results from NOTCH3 gene mutations, which lead to the degeneration of vascular smooth muscle cells (VSMCs). The clinical presentation of CADASIL patients is dependent on the impact of other vascular risk factors and the type of NOTCH3 mutation present. </p> <p> Methods: Here, we report a rare pathogenic mutation on exon 14 of the NOTCH3 gene in a Chinese family affected by CADASIL with phenotypic peculiarities. We performed genetic testing, clinical and neuropsychological examination, brain magnetic resonance images (MRI), and electron microscopy (EM) in skin biopsies. </p> <p> Results: NOTCH3 gene analysis revealed a c.2182C>T substitution on exon 14, which is the first example of this mutation in a Chinese individual from the Han ancestry. Granular osmiophilic material (GOM) was found in the proband, and all patients had migraine, subcortical ischemic events, and mood disturbances, without progressive cognitive impairment. Cranial MRI further showed white matter hyperintensity, involving bilateral basal ganglia and multiple microbleeds (MBs), in the thalamus and brain stem. </p> <p> Conclusions: This study suggests that different missense mutations in NOTCH3 might contribute to atypical clinical features of CADASIL. This report also indicates that for individuals with a positive family history having clinical and neuroradiological findings suggestive of CADASIL, genetic testing and GOM detection should be performed.]]></description> </item><item><title><![CDATA[New Molecular Targets of Anticancer Therapy – Current Status and Perspectives]]></title><link>https://www.benthamscience.comarticle/77764</link><description><![CDATA[Molecularly targeted anticancer therapy involves the use of drugs or other substances affecting specific molecular targets that play a part in the development, progression and spread of a given neoplasm. By contrast, the majority of classical chemotherapeutics act on all rapidly proliferating cells, both healthy and cancerous ones. Target anticancer drugs are designed to achieve a particular aim and they usually act cytostatically, not cytotoxically like classical chemotherapeutics. At present, more than 300 biological molecular targets have been identified. The proteins involved in cellular metabolism include (among others) receptor proteins, signal transduction proteins, mRNA thread matrix synthesis proteins participating in neoplastic transformation, cell cycle control proteins, functional and structural proteins. </p> <p> The receptor proteins that are targeted by currently used anticancer drugs comprise the epithelial growth factor receptor (EGFR), platelet-derived growth factor receptor (PDGFR) and vascular endothelial growth factor receptor(VEGFR). Target anticancer drugs may affect extracellular receptor domains (antibodies) or intracellular receptor domains (tyrosine kinase inhibitors). </p> <p> The blocking of the mRNA thread containing information about the structure of oncogenes (signal transduction proteins) is another molecular target of anticancer drugs. That type of treatment, referred to as antisense therapy, is in clinical trials. </p> <p> When the synthesis of genetic material is disturbed, in most cases the passage to the next cycle phase is blocked.

We also discuss expression and signalling of oxysterol-producing enzymes such as CH25H and CYP7B1 in the CNS and the immune system.

Astrocytes, the most abundant glial cell, increase in size and number evolutionarily such that invertebrates contain fewer small astrocytes, while humans have large multi-branched astrocytes that constitute up to 60% of central nervous system (CNS) cells. Astrocytes provide neurotrophic support, induce synaptogenesis and are integral for maintenance and pruning of synapses in the adult. Following injury and in disease, their ability to respond to, and initiate initial responses to injury/disease is increasingly apparent - with alterations in function that disrupt the internal milieu of the CNS, which ultimately may lead to deficits in neuronal health and functioning. Additionally, it seems certain astrocytes serve as liaison between the CNS and the peripheral immune system. In this role, astrocytes function much like macrophages, capable of phagocytosis and production of antigens to recruit additional immune cells. Aside from up-regulation of traditional immune modulators after injury, astrocytes express many adhesion molecules such as VCAM1, NCAM1 and ICAM1, which represent potential drug targets in a number of CNS inflammatory diseases. These molecules may facilitate astrocyte-lymphocyte interactions ultimately aiding recruitment of immune cells into the CNS. Due to their immense numbers and widespread presence in the brain, combined with their capacity for rapid proliferation, astrocytes are well-positioned as gate-keepers of CNS immune responses. Beyond roles in immune and inflammatory activities, astrocytes also affect a complex array of neural functions and behaviours like mood, sleep, and pain, as well as altering the CNS capacity for recovery following injury/illness. Further, their complex effects on synaptic function suggest that astrocytes are key players in neuropsychiatric and neurodegenerative diseases.]]></description> </item><item><title><![CDATA[Sphingosine-1-Phosphate Receptors in the Central Nervous and Immune Systems]]></title><link>https://www.benthamscience.comarticle/70785</link><description><![CDATA[Sphingosine-1-phosphate receptor (S1PR) modulators have entered clinical practice as immune-modulators for the treatment of multiple sclerosis (MS). Pharmacologic modulation of S1PR expression on lymphocytes inhibits these cells capacity to respond to the S1P gradient within regional lymph nodes (LNs) (and thymus) that promotes their exit into peripheral circulation. The resultant peripheral blood restricted lymphopenia is considered to underlie the capacity of S1PR modulators to reduce new inflammatory lesion formation in MS in the absence of global immune suppression. These modulators also regulate entry of selective lymphocyte populations and dendritic cells (DCs) into LNs and modulate sphingosine-1-phosphate (S1P) cell signaling networks that govern the generation of specific cell subsets within LNs. S1PR modulators that access the CNS can also have functional effects within this compartment since S1PRs are expressed by cells comprising the blood brain barrier (BBB) and by those within the parenchyma, including neurons, astrocytes, oligodendrocytes and microglia. Absence of S1P1 receptor (S1PR1) on astrocytes reduces disease severity in experimental autoimmune encephalomyelitis (EAE). Even under conditions that inhibit cell responses to the natural ligand, S1PR modulators can continue to induce active signaling responses; such responses may be relevant for promoting neuroprotection and augmenting tissue repair within the CNS.]]></description> </item><item><title><![CDATA[‘Non-Criteria’ Neurologic Manifestations of Antiphospholipid Syndrome: A Hidden Kingdom to be Discovered]]></title><link>https://www.benthamscience.comarticle/78442</link><description><![CDATA[Neurological manifestations or disorders associated with the central nervous system are among the most common and important clinical characteristics of antiphospholipid syndrome (APS). Although in the most recently updated (2006) APS classification criteria, the neurological manifestations encompass only transient ischemic attack and stroke, diverse ‘non-criteria’ neurological disorders or manifestations (i.e., headache, migraine, bipolar disorder, transverse myelitis, dementia, chorea, epileptic seizures, multiple sclerosis, psychosis, cognitive impairment, Tourette’s syndrome, parkinsonism, dystonia, transient global amnesia, obsessive compulsive disorder and leukoencephalopathy) have been observed in APS patients. To date, the underlying mechanisms responsible for these abnormal neurological manifestations in APS remain unclear. In vivo experiments and human observational studies indicate the involvement of thrombotic events and/or high titers of antiphospholipid antibodies in the neuro-pathogenic cascade of APS. Although different types of neurologic manifestations in APS patients have successfully been treated with therapies involving anti-thrombotic regimens (i.e., anticoagulants and/or platelet antiaggregants), antineuralgic drugs (i.e., antidepressants, antipsychotics and antiepileptics) and immunosuppressive drugs alone or in combination, evidence-based guidelines for the management of the neurologic manifestations of APS remain unavailable. Therefore, further experimental, clinical and retrospective studies with larger patient cohorts are warranted to elucidate the pathogenic linkage between APS and the central nervous system in addition to randomized controlled trials to facilitate the discovery of appropriate medications for the ‘non-criteria’ neurologic manifestations of APS. ]]></description> </item><item><title><![CDATA[Traumatic Brain Injury and Blood-Brain Barrier Cross-Talk]]></title><link>https://www.benthamscience.comarticle/77765</link><description><![CDATA[Traumatic brain injury, often referred to as the “silent epidemic,” is a nondegenerative, non-congenital insult to the brain due to a blow or penetrating object that disrupts the function of the brain leading to permanent or temporary impairment of cognition, physical and psychosocial functions. Traumatic brain injury usually has poor prognosis for long-term treatment and is a major cause of mortality and morbidity worldwide; approximately 10 million deaths and/or hospitalizations annually are directly related to traumatic brain injury. Traumatic brain injury involves primary and secondary insults. Primary injury occurs during the initial insult, and results from direct or indirect force applied to the physical structures of the brain. Secondary injury is characterized by longer-term degeneration of neurons, glial cells, and vascular tissues due to activation of several proteases, glutamate and pro-inflammatory cytokine secretion. In addition, there is growing evidence that the blood-brain barrier is involved in the course of traumatic brain injury pathophysiology and has detrimental effects on the overall pathology of brain trauma, as will be discussed in this work.]]></description> </item><item><title><![CDATA[Is There Any Scientific Basis of Hawan to be Used in the Alzheimer’s Disease Prevention/Cure?]]></title><link>https://www.benthamscience.comarticle/77265</link><description><![CDATA[Alzheimer’s disease (AD) is a neurodegenerative disorder of the central nervous system. As per modern science and ancient literature on medicine, nasal drug delivery systems are the best for the diseases related to brain and head. In older times Rishi Muni, ancient scholars and physicians used to recommend Hawan for mental peace and well being. Mritunjay Mantra also tells that sughandhim (aroma, fragrance) gives rise to good health. </p> <p> Om triambkum yajamahe, sughandhim puushtivardhanam, urvarukmev vandhanaat, mrityu mokshay mamritaat!!!! </p> <p> Hawan is a scientific experiment in which special herbs (Hawan Samagri) are offered in the fire of medicinal woods ignited in a specially designed fire pit called agni-kuñda. Aromatherapy was also employed in ancient times for a number of mental disorders. The hypothesis is based on action of Hawan components on Alzheimer Disease through integration of modern and ancient concepts. Hawan seems to be designed by the ancient scholars to fight with the diseases of the brain. Our review demonstrates that the components of Hawan are having a number of volatile oils that are specifically useful for AD through one or the other mechanism of action. Due to high temperature of fire the vapors of these oils enter into the central nervous system through nasal route. The routine of performing Hawan might keep the threshold value of the therapeutic components in the body and help in preventing AD. In the present manuscript authors have tried to highlight and integrate the modern and ancient concepts for treatment and prevention of AD.]]></description> </item><item><title><![CDATA[Drugs as Possible Triggers of Takotsubo Cardiomyopathy: A Comprehensive Literature Search - Update 2015]]></title><link>https://www.benthamscience.comarticle/74796</link><description><![CDATA[Background: In 2011 a list of 20 drugs linked to drug-induced Tako-Tsubo cardiomyopathy (TCM) was published. Thus, the objectives were both to identify cases of drug-induced TCM, and update the 2011 list of drugs as possible triggers of this cardiomyopathy. </p><p> Method: As the 2011 report of drug-induced TCM, case reports of drug-induced TCM were identified by a comprehensive search in Medline/PubMed database. From December 2010 to March 2015 search terms were Takotsubo cardiomyopathy, Takotsubo cardiomyopathy, stress cardiomyopathy, transient-left-ventricular ballooning syndrome, ampulla cardiomyopathy, apical ballooning syndrome, OR broken heart syndrome; together with “iatrogenic”, “drug-induced”, OR “induced by”. Publications limited to English, Spanish, and French, in humans, and with full texts were retrieved. Articles that recognized any drug as a possible trigger of TCM were selected. </p><p> Results: Overall, 405 different references were retrieved and 67 were selected (62 case reports and 5 case series) involving 78 patient cases with TCM possibly associated to drugs were reviewed. At total of 44 drugs were recognized as possible drug-induced TCM, mainly with sympathetic effect, and 37 (84.1%) were different to those 20 identified in the 2011 review; therefore, a list of 57 drugs associated to TCM was obtained. </p><p> Conclusion: There are new case reports that linked drug-use with the development of TCM. The list of 57 drugs obtained is principally integrated by drugs that generate sympathetic overstimulation. Consequently, the recommendation “drug-induced TCM would be considered in patients with TCM, particularly those in which no clear emotional or stress trigger could be identified” is endorsed. </p><p>]]></description> </item><item><title><![CDATA[Disease Progression in HIV Late Presenters: the Role of HIV Clinical Indicator Diseases Prior to HIV Diagnosis]]></title><link>https://www.benthamscience.comarticle/75386</link><description><![CDATA[Background: Late diagnosis represents a major challenge in the control of HIV epidemics. The rate of disease progression is higher among late presenters. In Europe, HIV Clinical Indicator Diseases (CIDs) have been proposed to improve early diagnosis. </p><p> Objectives: Our observational study evaluated the presence of these HIV CIDs prior to HIV diagnosis among a population of late presenters and assessed its correlation to disease progression. </p><p> Method: A retrospective cohort study was conducted in HIV late presenters diagnosed from 2007 to 2013 at University Hospital of Ferrara (Italy). Hazard Ratios (H.R.s) for disease progression (new AIDS-events and death) were estimated by Cox proportional hazard model. </p><p> Results: We analysed 77 patients and we found that those with CIDs prior to HIV diagnosis (22%) had a 2.8 fold higher rate of disease progression compared to those without HIV CIDs (H.R. 2.82; 95% CI 1.21-6.53; P 0.02). Other factors associated with disease progression were AIDS presentation, HCV coinfection and Haemoglobin levels, with H.R.s of 3.14 (95%CI 1.23-7.99), 2.95 (95% CI 1.14-7.61) and 0.74 (95% CI 0.60-0.91), respectively. </p><p> Conclusion: HIV CIDs confer a higher risk for disease progression even after adjustment for these confounding factors. Evaluation of previous HIV CIDs at HIV diagnosis could be an additional tool to identify and better manage HIV late presenters with higher risks of disease progression. </p><p>]]></description> </item><item><title><![CDATA[Chemokines SNPs in HIV-1+ Patients and Healthy Controls from Northeast Brazil: Association with Protection against HIV-1 Infection]]></title><link>https://www.benthamscience.comarticle/73144</link><description><![CDATA[Background: HIV-1 virus is known to infect the host mainly through CD4+ T-lymphocyte cells, by interactions among the viral envelope proteins, CD4 receptor and HIV-1 coreceptors, such as chemokines receptors. Variations in the genes encoding HIV-1 coreceptors and their natural ligands have been shown to modify HIV-1 infection susceptibility and disease progression. </p><p> Methods and Results: We analysed the distribution of SNPs in chemokines (CCL3, CCL4, CCL5, CXCL12) and chemokine receptor (CXCR6) genes, in 268 HIV-1 infected patients (HIV-1+) and 221 healthy controls from Northeast Brazil, and their possible connection with susceptibility to HIV-1 infection. The genotyping were performed through allele specific fluorogenic probes using real time PCR. We observed that the T alleles and AT genotype of rs1719153 CCL4 SNP were more frequent in healthy controls (19.8% and 35.0%, respectively) than in HIV-1+ patients (T allele: 14.1%; OR=0.67; 95%CI=0.47-0.95; p-value=0.020; and AT genotype: 24.4%; OR=0.61; 95%CI=0.40- 0.93; p-value=0.021) after correcting for age and sex. The rs1719134 (CCL3) and rs1719153 (CCL4) SNPs presented linkage disequilibrium (D’=0.83). The AT haplotype frequency was increased in healthy controls (17.3%) in relation to HIV-1+ patients (11.0%; OR=0.62; 95%CI=0.42-0.93; p-value=0.020). </p><p> Conclusion: Since our results revealed an increased frequency of alleles and genotypes of CCL3/CCL4 SNPs and haplotype (CCL3-CCL4) among healthy controls, we suggest that these variations might have a potential protective role against HIV-1 infection. </p><p>]]></description> </item><item><title><![CDATA[Could Better Phenotyping Small Vessel Disease Provide New Insights into Alzheimer Disease and Improve Clinical Trial Outcomes?]]></title><link>https://www.benthamscience.comarticle/73873</link><description><![CDATA[Alzheimer Disease (AD) is the most common primary cause of dementia with a burgeoning epidemic as life expectancy and general medical care improve worldwide. Recent data from pathologic studies has shown that the cooccurrence of other neurodegenerative and vascular pathologies is in fact the rule rather than the exception. In late onset AD, cerebral small vessel disease (SVD) is almost invariably co-existent to a greater or lesser extent and is known to promote cognitive deterioration. Previous observational studies and clinical trials have largely sought to divide dementia based on predominant neurodegenerative or vascular mechanisms. Given the high degree of overlap, findings from such studies may be difficult to interpret and apply to population cohorts. Additionally opportunities may be lost for uncovering novel interventions that target interactions between co-existent vascular and neurodegenerative pathologies. In the current review, we consider potential pathophysiologic mechanisms through which SVD may be associated with and promote AD pathology. In particular we explore shared environmental and genetic associations and how these may converge via neuroinflammatory pathways potentially providing novel therapeutic targets. SVD has heterogenous manifestations on cerebral imaging and at pathology. We discuss how studying SVD topography may enable us to better identify those at risk for more rapid cognitive decline and improve future clinical trial design.]]></description> </item><item><title><![CDATA[Studies on Chloride Channels and their Modulators]]></title><link>https://www.benthamscience.comarticle/72517</link><description><![CDATA[The prime roles of mutations in the genes, encoding chloride ion channels, in various human diseases of muscle, kidney, bone and brain, such as congenital myotonia, myotonic dystrophy, cystic fibrosis, osteopetrosis, epilepsy, glioma, etc., have been well established.

Although the underlying etiology of these disorders differs, disturbances in gait and balance appear to reflect deficits in cholinergic pathways within the brain. During the past 40 years, both clinical case studies and preclinical data have provided evidence that nicotinic cholinergic activation is beneficial for alleviating gait and balance deficits in many disorders. Further, studies indicate that activation of neuronal nicotinic receptors leads to neuroprotective and neurotrophic actions. And yet, despite these findings, there hsas been no concerted effort to develop neuronal nicotinic agonists for the treatment of abnormal gait and balance. The goal of this review is to shed light on the therapeutic benefit of the cholinergic nicotinic system for the treatment of ataxia, and discuss the challenges and limitations associated with developing drugs to treat disorders involving deficits in gait and balance.]]></description> </item><item><title><![CDATA[CEST MRI for Molecular Imaging of Brain Metabolites]]></title><link>https://www.benthamscience.comarticle/73603</link><description><![CDATA[As a sensitive MRI method, Chemical Exchange Saturation Transfer (CEST) MRI based on endogenous contrast has been increasingly utilized for molecular imaging of various metabolites. Among these applications, the authors have described CEST MRI for molecular imaging of brain metabolites in this review, including brain glutamate, the most abundant excitatory neurotransmitter; creatine, a key molecular of bioenergetics; and myo-inositol, a biomarker of glial cells. Those metabolites conventionally have been quantified with MR spectroscopy methods. Compared to MR spectroscopy, CEST methods typically provide a few hundred to a few thousand fold enhancement in sensitivity, enabling twodimensional imaging or mapping of metabolites at high resolution. In this review, the authors have also reviewed the preliminary applications of these molecular imaging methods. Finally, the challenges related to CEST MRI for molecular imaging in general are discussed.]]></description> </item><item><title><![CDATA[Editorial: Cocaine and Cerebral Small Vessel: Is it a Negative Factor for Intravenous Thrombolysis?]]></title><link>https://www.benthamscience.comarticle/73510</link><description><![CDATA[]]></description> </item><item><title><![CDATA[SAMHD1 in Retroviral Restriction and Innate Immune Sensing – Should We Leash the Hound?]]></title><link>https://www.benthamscience.comarticle/73929</link><description><![CDATA[Background: The antiviral restriction factor SAM domain and HD domain-containing protein 1 (SAMHD1) is a dNTP triphosphohydrolase and thereby contributes to the regulation of intracellular dNTP levels. SAMHD1 blocks retroviral infection at the level of reverse transcription in myeloid cells and resting CD4+ T cells and is counteracted by the accessory protein Vpx, which is encoded by human immunodeficiency virus 2 (HIV-2) and several simian immunodeficiency virus (SIV) strains. Recently, it has been shown that the antiviral activity of SAMHD1 in myeloid dendritic cells (DC) hampers the induction of an efficient immune response directed against HIV-1. Conclusion: Within this review, we will summarize recent advances on the biology of SAMHD1 and its function as an antiviral restriction factor. In addition, we will discuss its role in autoimmunity and the antiviral immune response directed against HIV-1 and will evaluate the possibility of modulating SAMHD1 activity to generate an enhanced antiretroviral immune response.]]></description> </item><item><title><![CDATA[Biologic Therapy in Immune Mediated Inflammatory Disease: Basic Science and Clinical Concepts]]></title><link>https://www.benthamscience.comarticle/71067</link><description><![CDATA[During the last decades, the advent of biological therapies has revolutionized the management of several immune-mediated inflammatory disorders, as inflammatory bowel diseases, autoimmune arthritis and psoriasis, which significantly impact both quality of life and health care economics. Biological therapies currently available can be divided into two main categories: the tumor necrosis factor-&#945; antagonists (infliximab, adalimumab, etanercept, golimumab, certolizumab pegol) and interleukin 12/23 monoclonal antibodies (ustekinumab). </p> <p> Biologics, reducing TNF&#945; bioavailability or inhibiting proximal regulators of inflammatory cascade, represent an established therapeutic strategy of inflammatory autoimmune diseases, with remarkable efficacy and a safety profile that is extensively examined and monitored. </p> <p> The biology and the immunological effects of TNF&#945;, IL-12, IL-23 and related signalling pathways are accurately summarized.

Patients present with a variety of symptoms ranging from headache, altered mental status, seizures and vision abnormalities to loss of consciousness. In cases with severe clinical manifestations, such as coma and/or status epilepticus, admission to the intensive care unit may be required. PRES is usually characterized by altered signal intensity in subcortical white matter of posterior cerebral hemispheres in magnetic resonance imaging (MRI) studies and resolve in weeks with appropriate treatment. Diagnosis depends on combination of suggestive clinical findings and radiological features. With increasing experience on PRES, atypical imaging features are described in case series. In this pictorial review, wide imaging feature spectrum of PRES is illustrated including unusual locations and atypical manifestations. Since MRI contributes to an essential part of the diagnosis, atypical imaging features of this syndrome should be well known by physicians and radiologists in order to recognize and treat it immediately. In suitable cases with atypical radiological features in the absence of classical findings, diagnosis of PRES should be kept in mind to avoid delay in diagnosis and hence, permanent neurological sequela.]]></description> </item><item><title><![CDATA[The CCL2/CCR2 Axis in the Pathogenesis of HIV-1 Infection: A New Cellular Target for Therapy?]]></title><link>https://www.benthamscience.comarticle/72575</link><description><![CDATA[The identification of chemokine receptors as necessary co-receptors for HIV entry into target cells represented a breakthrough in the understanding of the pathogenesis of this viral infection. Since this initial discovery, it was unraveled that chemokines, in addition to their role in blocking viral entry by binding to co-receptors, have other functions in HIV pathogenesis. Indeed, chemokines can either inhibit or enhance HIV replication, and these effects may involve both entry and post-entry events of the viral life cycle. Depending on the balance of their negative versus positive effects on HIV replication and spreading, chemokines contribute to different outcomes of HIV pathogenesis. CCL2 is unique among the chemokines in that mostly enhancing effects on viral replication and pathogenesis have been reported. Either HIV infection itself or exposure to viral products can induce the expression of this chemokine and of its receptor CCR2, and high levels of CCL2/CCR2 are indeed found in HIV-infected subjects. The CCL2/CCR2 axis is tightly linked to the high level of immune activation and inflammation that is the hallmark of HIV infection even in patients undergoing antiretroviral therapy. In addition, more direct effects of CCL2 on HIV replication are becoming apparent. Thus, modulation of CCL2/CCR2-driven effects may have significant impact on HIV disease progression. In this review, we will discuss the complex interaction between CCL2/CCR2 and HIV and the emerging therapeutic approaches based on the inhibition of this axis.]]></description> </item><item><title><![CDATA[Gut Homing Molecule Regulation of the Pathogenesis and Treatment of Inflammatory Bowel Diseases]]></title><link>https://www.benthamscience.comarticle/69765</link><description><![CDATA[Inflammatory bowel disease is a chronic, debilitating immunological disorder for which there are few effective treatments. New therapies targeting gut homing molecules, such as CCR9 and &#945;<sub>4</sub>&#946;<sub>7</sub>, are currently in development, with some of these reaching clinical trials. Gut-trophic molecules and their receptors are critical to the development of both tolerant and inflammatory immune responses in the gut. However, we know little regarding the function of homing molecules as it relates to IBD. Data have suggested both pathological and protective roles for gut homing molecules in IBD development and maintenance. In addition, recent research findings have suggested that chemokines can influence T cell differentiation and function. Given the current clinical relevance, it is essential to obtain a better understanding of the role of gut homing molecules in the regulation of IBD.]]></description> </item><item><title><![CDATA[Micro- and Nano-particulate Strategies for Antigen Specific Immune Tolerance to Treat Autoimmune Diseases]]></title><link>https://www.benthamscience.comarticle/71839</link><description><![CDATA[An improper immune response towards a self-antigen can result in an autoimmune disease. Commonly these diseases are treated with therapies that suppress overall immune responses, which can lead to increased risk of infection and cancer. A more specific method would be to induce immune tolerance in an antigen specific manner. This is much like traditional vaccines that have antigen specificity towards the pathogen they are forming protection. This antigen specific protection is called immune tolerance and has been accomplished by introducing soluble antigen to mucosal routes (e.g. oral, nasal or sublingual). Unfortunately, this approach has shown limited success clinically. Nano and microparticles (MPs) have recently been applied as delivery vehicles to help improve efficacy in immune tolerance. MPs can increase the solubility and circulation of cargo and passively target macrophages and dendritic cells. Fabrication of MPs with diseaseassociated antigens has limited disease progression in animal models of Multiple Sclerosis, Type 1 Diabetes, and Rheumatoid Arthritis, which has corresponded to an antigen specific decrease in inflammatory responses. The use of MPs to induce antigen specific tolerance can limit the current therapeutic shortfalls such as adverse drug side effects and blanket suppression of the immune system, which can lead to an overall significant increase in patient quality of life.]]></description> </item><item><title><![CDATA[Interplay between Catalysts and Substrates for Activity of Class Ib Aminoacyl-tRNA Synthetases and Implications for Pharmacology]]></title><link>https://www.benthamscience.comarticle/69652</link><description><![CDATA[Aminoacyl-tRNA synthetase:transfer RNA (aaRS:tRNA) systems became recently essential targets in molecular medicine, because perturbed recognition of cognate tRNAs by aaRSs and poor precision in tRNA aminoacylation do not guarantee accurate protein biosynthesis, thus leading to diseases. Sets of identity determinants situated at particular zones of tRNA are responsible for functional accuracy. Recent work in X-ray crystallography has revealed various snapshots of aaRS:ligand complexes which represent the stages required for aminoacylation. Here we focus on a small group of class I aaRSs conserved in evolution, the ArgRSs, GluRSs, GlnRSs, and atypical LysRSs found mostly in Archaea and in a few Bacteria, that catalyze amino acid activation only in the presence of their cognate tRNAs. Structural and functional features of these aaRSs, ranked in subclass Ib, together with their peculiar mode of tRNA recognition and identity expression are reviewed and compared. Strategies to inhibit class Ib aaRS:tRNA aminoacylation systems, their dysfunction leading to human diseases, and the implications for pharmacology are outlined.]]></description> </item><item><title><![CDATA[Expression of Signaling Molecules in Progressive Multifocal Leukoencephalopathy]]></title><link>https://www.benthamscience.comarticle/71525</link><description><![CDATA[Introduction: Progressive multifocal leukoencephalopathy (PML) is a debilitating demyelinating disease of the CNS caused by the infection and destruction of glial cells by JC virus (JCV) and is an AIDS-defining disease. Infection with JCV is common and most people acquire antibodies early in life. After initial infection, JCV remains in an asymptomatic persistent state and can be detected by PCR in many tissues including brain. A major question in PML pathogenesis is how the virus reactivates from persistence in HIV-1/AIDS. Our studies with primary cultures of glial cells have implicated transcription factors NF-&#954;B and NFAT4, which bind to a unique site in the JCV noncoding control region and stimulate viral gene expression. Furthermore, these transcription factors are controlled by pathways downstream of proinflammatory cytokines, e.g., TNF-&#945; activates NF-&#954;B and stimulates JCV transcription. </p> <p> Objectives: We hypothesize that HIV-1/PML initiation may involve reactivation of JCV by cytokine disturbances in the brain such as occur in HIV-1/AIDS. In this study, the objective was to evaluate HIV-1/PML clinical samples for expression of TNF-&#945; and its receptors and subcellular localization of NF-&#954;B p65 and NFAT4 compared to non-PML controls. </p> <p> Methods: We evaluated HIV-1/PML clinical samples and non-PML controls for expression of TNF-&#945; and its receptors and subcellular localization of NF-&#954;B p65 and NFAT4 using Western blot and immunohistochemistry. </p> <p> Results: Consistent with our hypothesis, compared to non-PML controls, HIV-1/PML tissue has high levels of TNF-&#945; and TNFR1 expression and NF-&#954;B and NFAT4 were preferentially localized to the nucleus. </p> <p> Conclusion: The involvement of TNF-&#945;/NF-&#954;B/NFAT4 signaling in JCV regulation that we reported from experiments in cultured human glial cells may be clinically relevant in PML.]]></description> </item><item><title><![CDATA[The Role of Disproportionality Analysis of Pharmacovigilance Databases in Safety Regulatory Actions: a Systematic Review]]></title><link>https://www.benthamscience.comarticle/69145</link><description><![CDATA[Introduction: Disproportionality analysis (DA) of adverse drug reactions spontaneous reporting (SR) databases is used to identify signals of disproportionate reporting (SDR). The objective of this study was to identify the generation of SDR in the published literature and whether it led to regulatory action. </p> <p> Methods: A systematic literature search in MEDLINE and Cochrane Central Register for Controlled Trials (CENTRAL) in a 10-year period, from 2005 to 2014, was conducted, to identify studies designed to detect drug safety signals through the use of disproportionality measures applied to spontaneous reporting databases of adverse drug reactions. </p> <p> Results: Seventy three studies were included. The number of publications has been rising over the study time period. Forty nine studies focus on drug-event combinations. Large international and smaller national or regional databases were identified. The disproportionality measures applied included frequentist and Bayesian methods and some studies used more than one method. SDRs were identified in more than ninety percent of the studies. Ten studies were found to be confirmatory of previous regulatory decision. </p> <p> Conclusion: It was not found any safety signal issued by drug regulatory agencies exclusively generated by DA. More research devoted to this issue is needed, since the value of these methods on drug safety signaling and their impact on drug regulation actions remains to be established.]]></description> </item><item><title><![CDATA[Survey of Latin American Neuroimmunologists on the Treatment of Multiple Sclerosis with Monoclonal Antibodies]]></title><link>https://www.benthamscience.comarticle/66691</link><description><![CDATA[Natalizumab and alemtuzumab are monoclonal antibodies approved for the treatment of relapsing-remitting multiple sclerosis (RRMS).

A group of 26 doctors working at specific MS Units in seven different Latin American countries participated in the present study. All 26 neurologists had experience with natalizumab for the treatment of MS and were willing to discuss strategies for improving this treatment. Most neurologists had no confidence in starting a patient on natalizumab and alemtuzumab, which are new and efficient drugs approved by North American, European and most Latin American health agencies. The Latin American specialists felt they were not properly informed on daclizumab.
