Methods: Well-characterised probable AD subjects participating in two large clinical trials of Hydromethylthionine were classified into “typical AD” and “mixed” patterns based on FDG-PET images. VRFs, including hypertension, diabetes and dyslipidaemia, and MRI-derived White Matter Hyperintensities (WMHs) and brain fraction (as a measure of brain atrophy) were analysed to investigate the relationship between VRFs and AD subtypes.

Results: Of 794 participants, 533 (67.1%) were classified as typical AD and 261 (32.8%) were classified as mixed. Among VRFs, cardiovascular risks were significantly more frequent in typical AD (59%) than in mixed subtype (47%) (p = 0.002).

Discussion: We found that it was mainly hypertension that differed according to subtypes. Although brain atrophy is the main driver of cognitive impairment in patients with AD subtype, the microvascular pathology in the form of WMHs was significantly higher in patients with hypertension, irrespective of subtype.

Conclusion: Although hypertension is the main risk factor for cerebrovascular disease, contrary to our expectation, hypertension is common in typical AD than the mixed subtype, and this association is driven by the hitherto unsuspected contribution of microvascular pathology to cognitive impairment in typical AD.

Methods: To comprehend the concept of this disease condition, a number of medical textbooks were consulted. Various search engines, such as PubMed, Google Scholar, Research Gate, Science Direct, Scopus, etc., were cited to explore the recent advancements and obtain data on the topic in question. Later, all the information and data gathered were organised into a review article.

Conclusion: Anemia, often referred to as the “haematological mask” of hypothyroidism, can manifest even before hypothyroidism is clinically diagnosed. Hypothyroidism must be considered as a potential cause when confronted with refractory anemia, as its treatment is pivotal for achieving comprehensive and lasting improvements in haematological parameters.

Methods: For this purpose, 18 male Wistar rats (220–250g) were divided into three groups including (i) Sham, (ii) I/R, and (iii) fingolimod+I/R. The last group was pretreated with a single dose of fingolimod (1mg/kg) (intraperitoneal injection) before induction of the I/R injury. Kidney function, oxidative stress marker (malondialdehyde), and antioxidant markers (catalase, superoxide dismutase, glutathione, glutathione peroxidase, and total antioxidant capacity) were determined in the kidney tissue of the rats. Moreover, kidney samples were taken for histological analysis.

Results: Fingolimod pre-treatment could significantly improve the glutathione peroxidase (p<0.01) and glutathione (p<0.001) activities along with the total antioxidant capacity levels (p<0.001) when compared to the I/R group. Moreover, significant recovery of kidney function and histology was seen in the fingolimod+ I/R group compared to the I/R group (p<0.01).

Conclusion: Fingolimod pretreatment could improve renal function, antioxidant capacity, and histological alterations after I/R injury. Hence, it might protect the kidney against IRI-related kidney damage including AKI and transplantation.

Objectives: The purpose of this article is to familiarize pediatricians with the clinical manifestations of lichen striatus to avoid misdiagnosis, unnecessary investigations, unnecessary referrals, and mismanagement of lichen striatus.

Methods: A search was conducted in June 2023 in PubMed Clinical Queries using the key term “Lichen striatus”. The search strategy included all observational studies, clinical trials, and reviews published within the past ten years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of this article.

Results: Lichen striatus is a benign self-limited T-cell mediated dermatosis characterized by a linear inflammatory papular eruption seen primarily in children. The onset is usually sudden with minimal or absent symptomatology. The eruption in typical lichen striatus consists of discrete, skin- colored, pink, erythematous, or violaceous, flat-topped, slightly elevated, smooth or scaly papules that coalesce to form a dull red, potentially scaly, interrupted or continuous band over days to weeks. Although any part of the body may be involved, the extremities are the sites of predilection. Typically, the rash is solitary, unilateral, and follows Blaschko lines. In dark-skinned individuals, the skin lesions may be hypopigmented at onset. Nails may be affected alone or, more commonly, along with the skin lesions of lichen striatus. The differential diagnoses of lichen striatus are many and the salient features of other conditions are highlighted in the text.

Conclusion: Lichen striatus is a self-limited condition that often resolves within one year without residual scarring but may have transient post-inflammatory hypopigmentation or hyperpigmentation. As such, treatment may not be necessary. For patients who desire treatment for cosmesis or for the symptomatic treatment of pruritus, a low- to mid-potency topical corticosteroid or a topical immunomodulator can be used. A fading cream can be used for post-inflammatory hyperpigmentation.

Objective: The use of Memantine, a non-competitive antagonist with low to moderate affinity for the NMDA (N-methyl-D-aspartate) receptor, has been approved for the treatment of mild to moderately severe Alzheimer's disease (AD). The efficacy of cholinesterase inhibitors (ChEIs) in the treatment of dementia varies depending on the drug type and ease of administration. Numerous techniques have been employed to evaluate the quality of life (QOL) of individuals suffering from dementia. QOL data is a well-established measure of an intervention's effectiveness. Up to now, cost-effectiveness studies have concentrated on both pharmaceutical and non-pharmacological therapy. Each unit of QoL-AD improvement costs USD27.82578 at mean values.

Methods: Searches were conducted to observe studies of the pharmacoeconomic impact of dementia medications with the help of previous articles published in journals and collected from Google Scholar with name search dementia or Alzheimer's cross-referenced with pharmacoeconomic or costs and effectiveness.

Objective: In this study, we propose a method that combines UNet and superpixel segmentation to address the problem of loss of detailed information in the feature extraction phase, leading to poor segmentation results at object edges. The aim is to provide a reproducible solution for diagnosing patients with lumbar disc herniation.

Methods: We suggest using the network structure of UNet. Firstly, dense blocks are inserted into the UNet network, and training is performed using the Swish activation function. The Dense-UNet model extracts semantic features from the images and obtains rough semantic segmentation results. Then, an adaptive-scale superpixel segmentation algorithm is applied to segment the input images into superpixel images. Finally, high-level abstract semantic features are fused with the detailed information of the superpixels to obtain edge-optimized semantic segmentation results.

Results: Evaluation of a private dataset of multifidus muscles in magnetic resonance images demonstrates that compared to other segmentation algorithms, this algorithm exhibits better semantic segmentation performance in detailed areas such as object edges. Compared to UNet, it achieves a 9.5% improvement in the Dice Similarity Coefficient (DSC) and an 11.3% improvement in the Jaccard Index (JAC).

Conclusion: The experimental results indicate that this algorithm improves segmentation performance while reducing computational complexity.

Methods: For the identification of GI illnesses, such as polyps, stomach ulcers, and bleeding, endoscopy is the gold standard in the medical imaging industry. The numerous images produced by endoscopy require an enormous amount of time for the specialist to diagnose the disease. It makes manual diagnosis difficult and has sparked research on automatic computer-based approaches to diagnose all the generated images quickly and accurately. AI-based algorithms have already been used in endoscopy images with promising outcomes and have enhanced disease identification and classification with precision. However, there are still a lot of issues to be solved, including figuring out potential biases in algorithms and improving interpretability and generalizability.

Results: The proposed GastroNet model creates a system for classifying digestive problems for the Kvasir Version 1 dataset. The framework consists of different CNN layers with multiple filters, and average max-pooling is used to extract image features. The optimization of network parameters is done using the Stochastic Gradient Descent (SGD) algorithm.

Conclusion: Finally, the robustness of the proposed model is compared with other state-of-the-art models like VGG 19, ResNet 50, Inception, and Xception in terms of evaluation metrics.

Methods: In this paper, functional brain imaging technology combining CT (computed tomography) and MRI (magnetic resonance imaging) was used for image fusion, and SURF (accelerated robust feature) feature points of images were extracted. In this study, 40 patients with mild and moderate closed traumatic brain injury admitted to the rehabilitation department of a rehabilitation center from 2018 to 2022 were selected as the research objects.

Results: Compared with using only CT images and MRI images for brain injury diagnosis, the fusion image had a higher detection rate of abnormal brain injury diagnosis, with a detection rate of 97.5%. When using fused images for the diagnosis of abnormal brain injury, the patient’s exercise rehabilitation effect was better.

Conclusion: CT and MRI image fusion technology had a high diagnostic accuracy for brain injury, which could timely guide doctors in determining exercise rehabilitation plans and help improve the effectiveness of patient exercise rehabilitation.

Case Report: This report presents a case of molybdenum cofactor deficiency type A (MoCD-A) caused by MOCS1 gene mutations. A male newborn was admitted on the 10th day of birth due to uncontrolled seizures and feeding difficulties. Brain MRI showed severe cerebral damage with multiple foci that did not enhance upon contrast administration. The diagnosis was confirmed by genetic analysis and the patient received rehabilitation. His parents also received genetic counseling. To the best of our knowledge, this is the first reported MoCD-A case that had enhanced MR imaging with Gd-DTPA (0.1 mmol/kg). In addition, we reviewed the clinical and neuroimaging features of 25 newborns diagnosed with MoCD-A, as documented in the existing literature.

Conclusion: MRI is crucial in the diagnosis of MoCD-A. A correct diagnosis can provide the family with timely genetic counseling to prevent future cases.

Methods: The radiology reports, and clinical records of 34 patients with nerve root compression caused by lumbar disc herniation or bulging and 21 healthy volunteers who had undergone magnetic resonance imaging (MRI) and DTI scan were retrospectively reviewed. The differences in fractional anisotropy (FA) and apparent diffusion coefficient (ADC) between compressed and non-compressed nerve roots from patients and the normal nerve roots from healthy volunteers were compared. Meanwhile, the nerve root fiber bundles were observed and analyzed.

Results: The average FA and ADC values of the compressed nerve roots were 0.254 ± 0.307 and 1.892 ± 0.346 10^-3mm²/s, respectively. The average FA and ADC values of the non-compressed nerve roots were 0.377 ± 0.659 and 1.353 ± 0.344 10^-3mm²/s, respectively. The FA value of compressed nerve roots was significantly lower than that of non-compressed nerve roots (P < 0.01). The ADC value of compressed nerve roots was significantly higher than that of non-compressed nerve roots. There were no significant differences between the left and right nerve roots of normal volunteers in FA and ADC values (P > 0.05). The nerve roots at different levels of L3-S1 had significantly different FA and ADC values (P < 0.01). Incomplete fiber bundles with extrusion deformation, displacement or partial defect were observed in the compressed nerve root fiber bundles. The real diagnosis of the clinical situation of the nerve can provide neuroscientists with an important computer tool to help them infer and understand the possible working mechanism from the experimental data of behavior and electrophysiology.

Conclusion: The compressed lumbosacral nerve roots can be accurately localized through 3.0T magnetic resonance DTI, which is instructive for accurate clinical diagnosis and preoperative localization.

Case Presentation: A 46-year-old middle adulthood male presented with unexplained fever, night sweats, abdominal distension for 3 months, and weight loss of around 7kg during almost 6 months, which is extremely similar to lymphoma from the clinical features and imaging examinations. After a clear diagnosis, the case not only obtained the opportunity of surgery but was also exempted from radiotherapy. The treatment effect was good. We report a case of rare metastatic embryonal carcinoma, which can provide insight into the diagnosis and treatment of embryonal carcinoma.

Conclusion: Metastatic embryonal carcinoma of abdominal lymph nodes can be highly similar to lymphoma; the diagnosis can only be based on clinical manifestations and imaging examination but also combined with patient history, tumor markers and biochemical examination. However, the final diagnosis depends on pathological biopsy.

Objective: To explore the clinical significance of renal lesions with low-level enhancement on CT after exposure to anti-cancer drugs.

Methods: Medical records of patients with cancer who developed renal lesions on CT after exposure to anti-cancer drugs were retrospectively reviewed. Renal lesions were scored according to the extent of involvement, CT attenuation values of lesions and normal parenchyma were measured on precontrast CT and three phases of contrast-enhanced CT, and changes in serum creatinine (SCr) from one week before exposure to drugs to one week before and after the appearance of renal lesions were recorded.

Results: This study included 54 patients (86 lesions). Lesions were slightly lower density on pre-contrast CT, and less enhancing than normal renal parenchyma, especially in the delayed phase. Lesions were wedge-shaped, and involved the renal pyramid and associated renal cortex, as well as, were single or multiple, and occurred in the unilateral or bilateral kidneys. There were patchy and cord-like shadows of increased density in adjacent perirenal adipose tissue. During follow-up, lesions disappeared in 15 patients and persisted in 39 patients without significant progression. There were significant differences in renal lesions and normal renal parenchyma CT attenuation values in each phase of contrast-enhanced CT. Change in SCr level was significantly positively correlated with lesion score.

Conclusion: Renal lesions with low-level enhancement on CT suggest early drug-induced kidney injury. These findings will inform clinical decision-making.

Methods: After the exclusion of the articles as per the exclusion criteria, the total articles that fulfilled the inclusive criteria were reviewed. In addition, all the articles were further cross-referenced for additional articles. All published papers retrieved from this search were considered for this review. A total of 22 records (26 cases) were found with a diagnosis of LRs in the kidney to date. Some articles were published as case series. Accordingly, 26 patients were reported to have Liesegang rings associated with kidney neoplastic and non-neoplastic conditions, 12 were male and 14 were female. For one case the gender was not mentioned. LRs presented a higher frequency in individuals between 4th and 5th decades of life. No single case was reported in infants and younger children. Regarding predisposing factors for LRs, cystic fluid contents were the most common underlying condition.

Results: In our practice, we encountered an unusual case of a 55-year-old female with a complaint of pain in the left upper quadrant of the abdomen. The ultrasound revealed nephrolithiasis and chronic kidney disease for which a nephrectomy was performed. On the histopathological examination, there was an incidental finding of Liesegang rings and a papillary adenoma along with features of chronic pyelonephritis. Our review will provide insight about LRs in different spectrums of kidney diseases.

Conclusion: This study represents the first available systematic review of the literature demonstrating LRs in the kidney. Although Liesegang rings have no great clinical significance, these, presence in both tissue and cytological specimens should be kept in mind while dealing with different lesions of the kidney as these are good mimickers of many organic and inorganic substances, parasites, and malignancies.

Methods: We searched the literature for studies on Google Scholar and PubMed using the keywords “Segmentation,” “Classification,” “medical image,” and “generative adversarial network.” Specifically, the initial search revealed 5423 publications after the removal of duplicated and non-accessible fulltext publications. Then, after the title and abstract screening, 680 underwent full-text screening. Finally, 121 studies were included in our final analysis after full-text screening.

Results: The date range of the studies covered in this review is from January 1, 2017, to the present. After a thorough screening and qualification assessment, 121 studies involving GAN-based applications in seven areas of medical images were included in the final methodological review. These areas included synthesis, classification, segmentation, conversion, reconstruction, denoising, and lesion detection. We further classified and summarized these papers into clinical applications, classification methods, and imaging modalities.

Conclusion: We thoroughly examined the latest research progress of GAN-based medical image augmentation. These techniques effectively alleviate the challenge of limited training samples for medical image diagnosis and treatment models. Furthermore, several critical issues associated with GANs, such as pattern collapse, instability, and lack of interpretability, require attention in future research.

Objective: The study aimed to demonstrate iron deposition in the brain of hypertensive patients using ESWAN.

Methods: Twenty-seven hypertension patients, with or without CMBs, and 16 matched healthy controls (HCs) were enrolled. From the post-processed ESWAN images, phase and magnitude values of the regions of interest (ROIs) were calculated. Two-sample t-test and one-way variance analysis were applied to compare groups. The relationship between ESWAN parameters and clinical variables was assessed using Pearson’s correlation coefficient.

Results: Compared to HCs, the phase value of the hippocampus, head of caudate nucleus (HCN), and substantia nigra (SN) was decreased in hypertension with the CMBs subgroup, while that of HCN and SN was decreased in hypertension without CMBs subgroup. Similarly, the magnitude value of the hippocampus, HCN, thalamus red nucleus, and SN was significantly lower in the hypertension group than HCs. In addition, the phase and magnitude values showed a correlation with clinical variables, including disease duration and blood pressure.

Conclusion: Deep grey matter nuclei displayed greater iron content in hypertension patients. Iron deposition may precede the appearance of CMBs on MRI, serving as a potential marker of microvascular damage.

Objectives: The aim of this study was to compare the effect of using an ENTPD for bedside placement of small bowel feeding tubes with blind placement on patients with acute severe pancreatitis and to see how well the electromagnetic navigation trajectory image (ENTI) and X-ray agreed on the location of the tube tip after placement.

Methods: The study was done prospectively using randomized and single-blind methods. The 65 cases used electromagnetic navigation-assisted placement, and 58 cases were blind placement. For judging the tube tip location, we compared the success rate, median time, number of repeat placements, complications, and agreement of ENTI vs. X-ray.

Results: The blind placement group's success rate was 86.21% compared to the ENTPD's 95.38%, P = 0.075. The median time was significantly longer in the blind placement group (116.55 ± 68.62 min vs. 25.37 ±12.63 min, P=0.000); the average number of repeating placements was 3.02 ± 1.21 vs. 1.16 ± 0.31 (Blind placement vs. ENTPD, P = 0.002). It provided a high degree of agreement between ENTI and X-ray after contrast, κ=0.752 [95% confidence interval, 0.67-0.84]. No complications occurred in the two groups.

Conclusion: ENTPD was used safely and effectively at the bedside to help patients with acute severe pancreatitis get feeding tubes. It not only improved the high successful rate of placement, decreased the time and reduced the exposure to X-ray, but it was also very convenient for bedside placement because of the portable equipment.

Methods: We used conventional brain structural imaging sequences and 3D pseudo-continuous arterial spin labeling (3D PCASL) to examine thirteen CM patients and fifteen normal controls (NCs). The entire brain gray matter underwent voxel-based analysis, and the cerebral blood flow (CBF) values of the altered positive areas were retrieved to look into the clinical variables' significant correlation.

Results: Brain regions with the decreased perfusion were located in the left postcentral gyrus, bilateral middle frontal gyrus, left middle occipital gyrus, left superior parietal lobule, left medial segment of superior frontal gyrus, and right orbital part of the inferior frontal gyrus. White matter fibers with decreased perfusion were located in bilateral superior longitudinal tracts, superior corona radiata, external capsules, anterior and posterior limbs of the internal capsule, anterior corona radiata, inferior longitudinal fasciculus, and right corticospinal tract. However, the correlation analysis showed no significant correlation between the CBF value of the above positive brain regions with clinical variables (p > 0.05).

Conclusion: The current study provided more useful information to comprehend the pathophysiology of CM and revealed a new insight into the neural mechanism of CM from the pattern of cerebral hypoperfusion.

Objective: The objective of this study is to determine the key features of obstructive sleep apnea syndrome (OSAS) using postmortem oral and pharyngeal computed tomography (CT).

Methods: We retrospectively assessed autopsy cases of patients with (n=25) and without (n=25) OSAS-related death. We used oral and pharyngeal CT images to compare the oral and pharyngeal cavity volume (OPCV), oral and pharyngeal soft tissue volume (OPSV), oral and pharyngeal air space volume (OPAV), and OPAV to OPCV ratio (%air). Receiver operating curve (ROC) analysis was used to determine the accuracy of OSAS prediction. We assessed participants with body mass index (BMI) values within the normal range.

Results: Among the 50 subjects, we observed significant between-group differences in OPSV, OPAV, and % air, whereas there were significant betweengroup differences in OPSV and %air among 28 subjects with normal BMI values. Both comparisons suggested that OSAS-related death was associated with low %air and high OPSV values.

Conclusion: The % air and OPSV are useful for assessing postmortem oropharyngeal CT images. OSAS-related sudden death is likely when %air and OPSV values are ≤20.1% and ≥127.2 ml, respectively. Among those with normal BMI values, % air and OPSV values of ≤22.8% and ≥111.5 ml, respectively, predict OSAS-related sudden death.

Methods: Literature review through a search in six electronic databases, structured in PICO format, without date restrictions. Looking for studies that used submaximal field walking tests in children and adolescents with congenital heart disease aged 5 to 18 years. Methodological quality, effectiveness and safety and risk of bias were assessed.

Results: Five studies met the eligibility criteria with a sample of 160 individuals with congenital heart disease, and all used the six-minute walk test. Note that different methodologies and modifications are used. Only the clinical trial showed good methodological quality.Four studies had low risk of bias and one study had moderate risk.

Conclusion: Although the six-minute walk test is the only test used as a field test found in our research, there is no standardization in the application of the test, making it difficult to compare the results. In this sense, reducing the limitations and heterogeneity in the application of the test will enable more concrete outcomes and facilitate their reproduction in clinical practice.

Objective: This work aimed to study the effects of post-translation modifications of α-Syn (pY39 and pS87) using all-atom Molecular Dynamics (MD) simulation.

Method: In this computational study, we used all-atom MD simulations to investigate the effects of phosphorylation (pY39 and pS87) on protein-membrane interaction. The MD trajectories obtained were analyzed, and secondary structural content was calculated using YASARA software to perform a salt-bridge interaction study. Also, Principal component analysis was performed to analyze the secondary minima and global minima of the phosphorylated proteins.

Results: From the MD study, we observed that phosphorylation at the Tyr 39 position in α-Syn has a marked effect on its interaction with the lipid membrane. The conformational snapshots of α-Syn obtained showed a high degree of fluctuations in the N-terminal region that disrupts the helix- 2 binding region. The secondary structures of pS87 α-Syn were found to be retained and influence the NAC region to immerse into the membrane while inhibiting the potential to interact with other neighbouring molecules. Moreover, it was observed that in the case of pY39 α-Syn as opposed to pS87 α-Syn, there were larger energy disparities between the local and global minima of the overall structure.

Conclusion: Therefore, disruption of the helix-2 binding region may affect the binding to the lipid membrane and take over interaction with other proteins or vesicles. In the case of pS87 α-Syn, the structure showed higher stability, but the NAC domain was found to emerge out of the membrane.

Methods: Mice were treated with hydroalcoholic extract of Artimisia dracunculus (HET) at two doses (250 and 500 mg/kg) for 14 days. The host hematological parameters, spleen cellularity histopathology, hemagglutination titer assay (HA), delayed-type hypersensitivity (DTH) responses, IFN-γ and IL-4 levels produced by spelenocytes, and the proliferation of lymphocytes were assayed.

Results: HET at a high dose significantly could increase the number of white blood cells and lymphocytes compared to the control group. The lymphocyte proliferation in exposure to PHA significantly increased in the HET group at both doses compared to the control group, whilst this index in the presence of LPS increased significantly for the 500 mg/kg-HET group only. Moreover, in the HA and DTH tests, HET significantly increased the proliferation of lymphocytes as compared with the control group. Furthermore, HET significantly increased the amount of IFN-γ parallel to a decrease in the level of IL-4 in compared to the control group.

Conclusion: Based on our findings, HET has potent immunostimulant characteristics. More investigation into tarragon's potential to be used in the treatment of disorders caused by a weakened immune response should be conducted.

Methodology: A literature review was carried out to identify studies that reported the association of genetic variants with structural and functional changes in the brain in AD patients. Databases like PubMed, Google Scholar, and Web of Science were accessed to retrieve relevant studies. Keywords like ‘fMRI’, ‘Alzheimer’s’, ‘SNP’, and ‘imaging’ were used, and the studies were screened using different inclusion and exclusion criteria.

Results: 15 studies that found an association of genetic variations with structural and functional changes in the brain were retrieved from the literature. Based on this, 33 genes were identified to play a role in the development of disease. These genes were mainly involved in neurogenesis, cell proliferation, neural differentiation, inflammation and apoptosis. Few genes like FAS, TOM40, APOE, TRIB3 and SIRT1 were found to have a high association with AD. In addition, other genes that could be potential candidates were also identified.

Conclusion: Imaging genetics is a powerful tool in diagnosing and predicting AD and has the potential to identify genetic biomarkers and endophenotypes associated with the development of the disorder.

Objectives: The objective of this review was to relate the consumption of probiotic bacteria and its effects on inflammatory diseases, including obesity, type II diabetes and celiac disease.

Methods: A search was carried out in English, between the years 2011 and 2022, for research articles and clinical trials with humans and in vivo studies. Research showed improvement in cardiovascular risk markers, and improvement in insulin sensitivity, lipid profile and plasma atherogenic index, in obesity with the use of probiotics. In type II diabetes, decreased levels of fasting glucose, glycated hemoglobin, insulin and glycemic index, and increased levels of peptide 1, superoxide dismutase and glutathione peroxidase were observed.

Results: In addition to cellular protection of the islets of Langerhans and positive alteration of TNF- α and IL-1β markers. Improvement in the condition of patients with celiac disease was observed, since the neutralization of the imbalance in serotonin levels was observed, reducing the expression of genes of interest and also, a decrease in cytokines.

Conclusion: Therefore, the use of probiotics should be encouraged.

Methods: We initially utilized pan-cancer transcriptomics to explore the expression, prognosis, and mutation status of genes related to disulfidptosis. Using the LUAD multi- -omics cohorts in the TCGA database, we explore the molecular characteristics of subtypes related to disulfidptosis. Employing various machine learning algorithms, we construct a robust prognostic model to predict immune therapy responses and explore the model's impact on the tumor microenvironment through single-cell transcriptome data. Finally, the biological functions of genes related to the prognostic model are verified through laboratory experiments.

Results: Genes related to disulfidptosis exhibit high expression and significant prognostic value in various cancers, including LUAD. Two disulfidptosis subtypes with distinct prognoses and molecular characteristics have been identified, leading to the development of a robust DSRS prognostic model, where a lower risk score correlates with a higher response rate to immunotherapy and a better patient prognosis. NAPSA, a critical gene in the risk model, was found to inhibit the proliferation and migration of LUAD cells.

Conclusion: Our research introduces an innovative prognostic risk model predicated upon disulfidptosis genes for patients afflicted with Lung Adenocarcinoma (LUAD). This model proficiently forecasts the survival rates and therapeutic outcomes for LUAD patients, thereby delineating the high-risk population with distinctive immune cell infiltration and a state of immunosuppression. Furthermore, NAPSA can inhibit the proliferation and invasion capabilities of LUAD cells, thereby identifying new molecules for clinical targeted therapy.

Objective: This review aims to summarize recent advances in the development of treatment strategies for FRDA, with a focus on potential drug candidates and their mechanisms of action.

Methods: A comprehensive literature search was conducted using various authentic scientific databases to identify studies published in the last decade that investigated potential treatment strategies for FRDA. The search terms used included “Friedreich's ataxia”, “treatment”, “drug candidates”, and “mechanisms of action”.

Results: To date, only one drug got approval from US-FDA in the year 2023; however, significant developments were achieved in FRDA-related research focusing on diverse therapeutic interventions that could potentially alleviate the symptoms of this disease. Several promising drug candidates have been identified for the treatment of FRDA, which target various aspects of frataxin deficiency and aim to restore frataxin levels, reduce oxidative stress, and improve mitochondrial function. Clinical trials have shown varying degrees of success, with some drugs demonstrating significant improvements in neurological function and quality of life in FRDA patients.

Conclusion: While there has been significant progress in the development of treatment strategies for FRDA, further research is needed to optimize these approaches and identify the most effective and safe treatment options for patients. The integration of multiple therapeutic strategies may be necessary to achieve the best outcomes in FRDA management.

Objectives: We have, in this paper, provided an overview of ACD and discussed common and unusual causes of ACD.

Methods: We performed an up-to-date literature review in the English language on “allergic contact dermatitis” via PubMed Clinical Queries, using the keywords “allergic contact dermatitis” in August 2022. The search included meta-analyses, randomized controlled trials, clinical trials, casecontrol studies, cohort studies, observational studies, clinical guidelines, case series, case reports, and reviews. The search was restricted to English literature and children.

Results: ACD may be acute or chronic and it affects more than 20% of children and adults with significant quality-of-life impairments. ACD is manifested by varying degrees of cutaneous edema, vesiculation, and erythema. The hypersensitivity reaction is one of the most prevalent forms of immunotoxicity in humans. Localized acute ACD lesions can be managed with high-potency topical steroids; if ACD is severe or extensive, systemic corticosteroid therapy is often required to provide relief within 24 hours. In patients with more severe dermatitis, oral prednisone should be tapered over 2-3 weeks. Rapid discontinuation of corticosteroids can result in rebound dermatitis. Patch testing should be performed if treatment fails and the specific allergen or diagnosis remains unknown.

Conclusion: ACD is common and can be a physically, psychologically, and economically burdensome disease. Diagnosis of ACD is primarily based on history (exposure to an allergen) and physical examination (morphology and location of the eruption). Skin patch test can help determine the causative allergen. Allergen avoidance is the cornerstone of management. Topical mid- or highpotency corticosteroids are the mainstay of treatment for lesions on less than 20% of the body area. Severe cases of ACD may require treatment with systemic corticosteroids.

Aim: We present a systematic review of musculoskeletal manifestations of adult-onset nonsurgical nongenetic hypoparathyroidism.

Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline using the MEDLINE database, including manuscripts describing musculoskeletal manifestations of adult-onset nonsurgical nongenetic hypoparathyroidism.

Results: Musculoskeletal manifestations included myopathy, shoulder disorder, immune-negative non-erosive peripheral arthritis, axial involvement simulating spondylarthritis, and diffuse ligamentous ossifications. An association between hypoparathyroidism and spondyloarthritis or autoimmune diseases is possible. T-cell activation, seen in patients with hypoparathyroidism, may explain the co-occurrence of hypoparathyroidism with other autoimmune diseases.

The treatment of these manifestations is based on calcium and active vitamin D supplementation. Parathyroid hormone may have an anabolic effect on muscle atrophy and muscle weakness. Parathyroid hormone can also promote bone formation and bone resorption by stimulating osteoclast differentiation by increasing RANKL (receptor activator for nuclear factor kappa-B ligand) expression. Therefore, hypoparathyroidism can be responsible for an increase in bone mineral density. However, the risk of fractures does not appear to be reduced due to changes in bone microarchitecture and the high risk of falls. Treatment with parathyroid hormone has been shown to improve bone microarchitecture.

Conclusion: Our review showed that musculoskeletal manifestations are frequent in patients with hypoparathyroidism, including muscular, axial, peripheral articular, and entheseal manifestations.

Method: In clinical practice, it remains a significant public health issue. Modern pharmacological studies have demonstrated that Magnolia Volatile Oil (MVO) has good anti-inflammatory, antibacterial, immunomodulatory, and other pharmacological effects. Previous research and literature reports have reported that MVO has good therapeutic effects on allergic rhinitis. However, due to the poor water solubility of Magnolia, its bioavailability is low. The purpose of this present work is to develop a new microemulsion formulation to improve the stability and bioavailability of MVO.

Results: The droplet size, PDI, and zeta potential of Magnolia volatile oil microemulsion (MVOME) were characterized along with its physical characteristics, and these values were found to be 14.270.03 nm, 0.09410.31, and -0.35850.12 mV, respectively, demonstrating the successful formation of microemulsion. In OVA-induced AR rats, MVO-ME dramatically reduced the serum levels of TNF-α, IL-1β, and IL-6 inflammatory factors. In addition, MVO-ME significantly inhibited the expression of protein levels of PPAR-γ and P65 in the nasal mucosa of AR rats. In this regard, we hypothesized that MVO-ME may play a therapeutic role in AR by activating the PPAR signaling pathway as well as inhibiting the activation of the NF/κB signaling pathway.

Conclusion: MVO-ME has systematic advantages, such as high solubility, bioavailability, etc. It is expected to be an efficient nano-drug delivery system for the clinical treatment of allergic rhinitis.

Objective: This study aims to reveal the anti-SMA mechanisms of securinine.

Methods: Securinine-associated targets were acquired from Herbal Ingredients' Targets (HIT), Similarity Ensemble Approach (SEA), and SuperPred. SMA-associated targets were obtained from GeneCards and Dis- GeNET. Protein-protein Interaction (PPI) network was constructed using GeneMANIA, and hug targets were screened using cytoHubba. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed using ClusterProfifiler. Molecular docking was conducted using Pymol and Auto- Dock. In vitro assays were used to verify the anti-SMA effects of securinine.

Results: Twenty-six intersection targets of securinine and SMA were obtained. HDAC1, HDAC2, TOP2A, PIK3R1, PRMT5, JAK2, HSP90AB1, TERT, PTGS2, and PAX8 were the core targets in PPI network. GO analysis demonstrated that the intersecting targets were implicated in the regulation of proteins, steroid hormones, histone deacetylases, and DNA transcription. KEGG analysis, pathway-pathway, and hub target-pathway networks revealed that securinine might treat SMA through TNF, JAK-STAT, Ras, and PI3K-Akt pathways. Securinine had a favorable binding affinity with HDAC1, HSP90AB, JAK2, PRMT5, PTGS2, and TERT. Securinine rescued viability suppression, mitochondria damage, and SMN loss in the SMA cell model. Furthermore, securinine increased HDAC1 and PRMT5 expression, decreased PTGS2 expression, suppressed the JAK2-STAT3 pathway, and promoted the PI3K-Akt pathway.

Conclusion: Securinine might alleviate SMA by elevating HDAC1 and PRMT5 expression and reducing PTGS2 via JAK2-STAT3 suppression and PI3K-Akt activation.

Background: Even though environmental and genetic predispositions have also been involved in the process, redox metal abuse plays a crucial role in neurodegeneration since the preponderance of symptoms originates from abnormal metal metabolism.

Method: Hence, this review investigates several neurodegenerative diseases that may occur symptoms similar to Parkinson's disease to understand the differences and similarities between Parkinson's disease and other neurodegenerative disorders based on reviewing previously published papers.

Results: Based on the findings, the aggregation of alpha-synuclein occurs in Parkinson’s disease, multiple system atrophy, and dementia with Lewy bodies. Other neurodegenerative diseases occur with different protein aggregation or mutations.

Conclusion: We can conclude that Parkinson's disease, Multiple system atrophy, and Dementia with Lewy bodies are closely related. Therefore, researchers must distinguish among the three diseases to avoid misdiagnosis of Multiple System Atrophy and Dementia with Lewy bodies with Parkinson's disease symptoms.

Objective: Abuse of alcohol does not occur suddenly. People becoming addicted to various alcoholic beverages is a problem that results from months and years of irresponsible drinking. The process of recovering from the issue in turn includes targeted, particular methods for raising awareness of the negative effects of alcohol usage.

Conclusion: Due to the heightened risks for one's bodily and mental health along with the social issues it generates, alcohol consumption results in these costs. We discuss the three areas of the epidemiology of alcohol's impact on health and diseases, the public health approach for treating problems related to alcohol use, and advancements in alcohol science.

Objective: In this research, we employed network pharmacology and molecular docking to examine the active compounds and biological mechanisms of Cucurbita pepo against kidney stones.

Methods: Active constituents were obtained from previous studies and the IMPPAT database, with their targets predicted using Swiss target prediction. Kidney stone-associated genes were collected from DisGeNET and GeneCards. The active constituent-target-pathway network was constructed using Cytoscape, and the target protein-protein interaction network was generated using the STRING database. Gene enrichment analysis of C. pepo core targets was conducted using DAVID. Molecular docking was performed to identify potential kidney stone-fighting agents.

Results: The findings revealed that Cucurbita pepo contains 18 active components and has 192 potential gene targets, including AR, EGFR, ESR1, AKT1, MAPK3, SRC, and MTOR. Network analysis demonstrated that C. pepo seeds may prevent kidney stones by influencing disease-related signaling pathways. Molecular docking indicated that key kidney stone targets (mTOR, EGFR, AR, and ESR1) effectively bind with active constituents of C. pepo.

Conclusion: These findings provide insight into the anti-kidney stone effects of Cucurbita pepo at a molecular level. In conclusion, this study contributes to understanding the potential of Cucurbita pepo in combating kidney stones and lays the foundation for further research.

Further cautions are required when paresthesia is acute (within days) in onset, rapidly progressive, severe, asymmetric, proximal, multifocal, or associated with predominant motor signs (limb weakness) or severe dysautonomia. Acroparesthesia may reveal Guillain-Barré syndrome or vasculitis, requiring rapid management.

Acroparesthesia is a predominant symptom of polyneuropathy, typically distal and symmetric, often due to diabetes. However, it can occur in other diseases such as vitamin B12 deficiency, monoclonal gammopathy of undetermined significance, or Fabry’s disease. Mononeuropathy, mainly carpal tunnel syndrome, remains the most common cause of acroparesthesia.

Ultrasonography contributes to the diagnosis of nerve entrapment neuropathy by showing nerve enlargement, hypoechogenic nerve, and intraneural vascularity. Besides, it can reveal its cause, such as space-occupying lesions, anatomical nerve variations, or anomalous muscle. Ultrasonography is also helpful for entrapment neuropathy treatment, such as ultrasound-guided steroid injection or carpal tunnel release.

The management of acroparesthesia depends on its causes.

This article aimed to review and summarize current knowledge on acroparesthesia and its causes.

We also propose an algorithm for the management of acroparesthesia.

Objective: Understanding the pathways and mechanisms of mitochondrial dysfunction related to neurodevelopmental disorders such as ADHD, Pelizaeus- Merzbacher Disease (PMD), mental retardation, Autism spectrum disorder, Rett's syndrome, and Fragile X syndrome is important. In this review, we discussed the possible factors associated with mitochondria that influence the clinical presentation of NDDs, better understanding of the mechanisms behind these pathways will hopefully be helpful for the diagnosis and treatment approaches.

Conclusion: Mitochondria are simply another subcellular victim of various neurodegenerative pathways, or are they a common denominator on the path to neurodegeneration? A better understanding of functional and molecular mechanistic pathways can lead to the identification of potential targets, thereby opening perspectives for future treatment.

Objective: In this work, we aimed to summarize the interesting results from preclinical and clinical studies that assessed the effects of natural alkaloids (berberine, nigelladine A, piperine, trigonelline, capsaicin, nuciferine, evodiamine, mahanine, and magnoflorine) on impaired insulin sensitivity and worsened insulin resistance, which play a pivotal role in the pathogenesis of type 2 diabetes.

Methods: In the current review, PubMed, ScienceDirect, Springer, and Google Scholar databases were used. The inclusion criteria were based on the following keywords and phrases: insulin sensitivity, insulin resistance, alkaloids and insulin resistance, alkaloids and type 2 diabetes, mechanisms of action, and alkaloids.

Results: The outcomes reported in this review demonstrated that the selected alkaloids increased insulin sensitivity and reduced insulin resistance in vitro and in vivo evidence, as well as in clinical trials, through improving insulin-signaling transduction mainly in hepatocytes, myocytes, and adipocytes, both at cellular and molecular levels. Insulin signaling components (InsR, IRS-1, PI3K, Akt, etc.), protein kinases and phosphatases, receptors, ion channels, cytokines, adipokines, and microRNAs, are influenced by alkaloids at transcriptional and translational levels, also in terms of function (activity and/or phosphorylation). Multiple perturbations associated with insulin resistance, such as ectopic lipid accumulation, inflammation, ER stress, oxidative stress, mitochondrial dysfunction, gut microbiota dysbiosis, and β-cell failure, are reversed after treatment with alkaloids. Furthermore, various indices and tests are employed to assess insulin resistance, including the Matsuda index, insulin sensitivity index (ISI), oral glucose tolerance test (OGTT), and insulin tolerance test (ITT), which are all enhanced by alkaloids. These improvements extend to fasting blood glucose, fasting insulin, and HbA1c levels as well. Additionally, the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) and the Homeostasis Model Assessment of β-cell function (HOMA-β) are recognized as robust markers of insulin sensitivity and β-cell function, and it is noteworthy that alkaloids also lead to improvements in these two markers.

Conclusion: Based on the findings of the current review, alkaloids may serve as both preventive and curative agents for metabolic disorders, specifically type 2 diabetes. Nonetheless, there is an urgent need for additional clinical trials to explore the potential benefits of alkaloids in both healthy individuals and those with type 2 diabetes. Additionally, it is crucial to assess any possible side effects and interactions with antidiabetic drugs.

Objective: This review describes the role of berberine and its metabolic effects. It also discusses how it plays a role in glucose metabolism, fat metabolism, weight loss, how it modulates the gut microbiota, and what are its antimicrobial properties along with its potential side effects with maximal tolerable dosage.

Methods: Representative studies were considered and analyzed from different scientific databases, including PubMed and Web of Science, for the years 1982-2022.

Results: Literature analysis shows that berberine affects many biochemical and pharmacological pathways that theoretically yield a positive effect on health and disease. Berberine exhibits neuroprotective properties in various neurodegenerative and neuropsychological ailments. Despite its low bioavailability after oral administration, berberine is a promising tool for several disorders. A possible hypothesis would be the modulation of the gut microbiome. While the evidence concerning the aging process in humans is more limited, preliminary studies have shown positive effects in several models.

Conclusion: Berberine could serve as a potential candidate for the treatment of several diseases. Previous literature has provided a basis for scientists to establish clinical trials in humans. However, for obesity, the evidence appears to be sufficient for hands-on use.

Objective: This review article is focused on the recent advancements in compounds that can inhibit the development of α-syn fibrillation and oligomerization.

Methods: The current review article is based on the most recent and frequently cited papers from Google Scholar, SciFinder, and Researchgate sources.

Description: In the progression of PD, the mechanism of α-syn aggregation involves the structural transformation from monomers into amyloid fibrils. As the accumulation of α-syn in the brain has been linked to many disorders, the recent search for disease-modifying medications mainly focused on modifying the α-syn aggregation. This review contains a detailed report of literature findings and illustrates the unique structural features, structure-activity relationship, and therapeutic potential of the natural flavonoids in the inhibition of α-syn are also discussed.

Conclusion: Recently, many naturally occurring molecules such as curcumin, polyphenols, nicotine, EGCG, and stilbene have been recognized to inhibit the fibrillation and toxicity of α-syn. Therefore, knowing the α-synuclein filament's structure and how they originate will help invent particular biomarkers for synucleinopathies and develop reliable and effective mechanism-based therapeutics. We hope the information this review provides may help evaluate novel chemical compounds, such as α- syn aggregation inhibitors, and will contribute to developing novel drugs for treating Parkinson’s disease.

Methods: To better reproduce the influence of this environmental factor in the pathogenesis of ALS, we exposed SOD1^G93A low-copy male mice to multiple exercise sessions at asymptomatic and pre-symptomatic disease stages in an automated home-cage running-wheel system for about 3 months.

Results: Repeated voluntary running negatively influenced disease progression by anticipating disease onset, impairing neuromuscular transmission, worsening neuromuscular decline, and exacerbating muscle atrophy. Muscle fibers and neuromuscular junctions (NMJ) as well as key molecular players of the nerve-muscle circuit were similarly affected.

Conclusion: It thus appears that excessive physical activity can be detrimental in predisposed individuals and these findings could model the increased risk of developing ALS in predisposed and specific professional athletes.

Objective: Therefore, the aim of this systematic review was to analyze their role in pathogenesis and usage as diagnosis or prognosis biomarkers in aging disorders.

Methods: In this study, a search on the Pubmed interface was performed for papers published from January 1953 to June 1^st, 2021.

Results: 45 articles have been included, which matched the eligibility criteria and evaluated the following diseases: breast cancer, prostate cancer, amyotrophic lateral sclerosis (ALS), osteoarthritis, Alzheimer's disease, immuno-senescence, cognitive impairment, cataract, glaucoma and hypertension.

Conclusion: In conclusion, the results suggested that HERVs play a role in the pathogenesis and can be used as biomarkers for the diagnosis or prognosis of aging disorders.

Objective: To investigate whether midbrain SERT uptake of F-18 FP-CIT on positron emission tomography (PET) could be applied to the differentiation of parkinsonism in combination with striatal DAT uptake.

Methods: This retrospective study included clinically diagnosed three essential tremors (ET), 53 parkinsonism patients (21 idiopathic Parkinson’s disease (IPD), 6 multiple system atrophy – cerebellar type (MSA-C), 7 multiple system atrophy - parkinsonian type (MSA-P), 8 vascular parkinsonism (VP), and 11 drug-induced parkinsonism (DIP)), and 16 healthy controls. The patient group consisted of 29 men and 27 women (age mean ± SD years, 69.9 ± 8.5 and 69.2 ± 8.9, respectively), and the healthy controls consisted of 8 men and 8 women (age mean ± SD years, 64.5 ± 8.2 and 64.3 ± 7.6, respectively). Mean standardized uptake values (SUVs) and activity volumes were measured from the visualized FP-CIT uptake of the midbrain (substantia nigra and dorsal raphe nucleus) as well as the striatum (caudate nucleus and putamen). The mean SUVs of the occipital region were measured as the background activity. The semiquantitative binding ratio (BR) was calculated using the following formula: BR = (SUVmean of the region of interest − SUVmean of background)/SUVmean of the background. SUV, volume, and BR in each type of parkinsonism were compared with those in healthy controls using both nonparametric and parametric methods. The correlation between the visual score of the qualitative analysis and the BR was examined.

Results: Except for the dorsal raphe nucleus in VP, the midbrain BRs in all parkinsonism showed a statistically significant decrease compared to those in healthy controls. Both midbrain and striatal BRs were significantly decreased only in patients with IPD or MSA-P; a greater decrease of substantia nigra BR was identified in MSA-P than in IPD (p < 0.05). The striatal BRs in MSA-C, VP, and DIP showed no significant difference from those in healthy controls. Finally, four patterns of uptake were identified: 1) decreased striatal and midbrain uptake for IPD and MSA-P, 2) normal striatal uptake and decreased midbrain uptake (both substantia nigra and dorsal raphe nucleus) for MSA-C and DIP, 3) normal striatal uptake and decreased substantia nigra uptake (without decreased dorsal raphe nucleus uptake) for VP, and 4) normal striatal and midbrain uptake for ET.

Conclusion: The possible differential diagnoses were split into two groups when only striatal uptake was considered but they were divided into four groups after adding midbrain uptake. Although additional midbrain F-18 FP-CIT uptake still could not make a final definitive diagnosis, it could provide another piece of information and specific diagnostic guidelines for the differentiation of parkinsonism.

Objective: The present study aims to review the radioprotective potentials of silymarin/silibinin in the prevention/reduction of ionizing radiation-induced adverse effects on healthy cells/tissues.

Methods: Based on PRISMA guidelines, a comprehensive and systematic search was performed for identifying relevant literature on the “potential protective role of silymarin/silibinin in the treatment of radiotherapy-induced toxicities” in the different electronic databases of Web of Science, PubMed, and Scopus up to April 2022. Four hundred and fifty-five articles were obtained and screened in accordance with the inclusion and exclusion criteria of the current study. Finally, 19 papers were included in this systematic review.

Results: The findings revealed that the ionizing radiation-treated groups had reduced survival rates and body weight in comparison with the control groups. It was also found that radiation can induce mild to severe adverse effects on the skin, digestive, hematologic, lymphatic, respiratory, reproductive, and urinary systems. Nevertheless, the administration of silymarin/silibinin could mitigate the ionizing radiation-induced adverse effects in most cases. This herbal agent exerts its radioprotective effects through anti-oxidant, anti-apoptosis, anti-inflammatory activities, and other mechanisms.

Conclusion: The results of the current systematic review showed that co-treatment of silymarin/silibinin with radiotherapy alleviates the radiotherapy-induced adverse effects in healthy cells/tissues

Objective: The present study was designed to evaluate the protective effects of Shogaol (an active component of ginger) in neuroinflammation and behavioral paradigms in mice treated with metals and HFD.

Methods: 8-11 weeks old male mice model was developed by giving a combination of metals, i.e., Arsenic (As), Lead (Pb) and Aluminum (Al), 25mg/kg each mixed in drinking water with laboratory prepared HFD (40% fat) for a total duration of 72 days. Shogaol treated groups received two doses (2mg/kg & 12mg/kg) of Shogaol along with metals and HFD. The biochemical parameters, including body weights, blood glucose, and kidney and liver functions, were assessed along with the integrity of the blood-brain barrier (BBB). The expression analysis of neuroinflammatory genes (TNF-α, IL-1β & GFAP) was performed using q-PCR in the hippocampus and cortex. The exploratory and anxiety-like behavior was assessed using an open field test, and depressive behavior was assessed through the forced swim test, while learning and memory were assessed using the Morris water maze test and y-maze test.

Results: Shogaol (2mg/kg & 12mg/kg) treatment improved metabolic profile and reduced expression of neuroinflammatory genes in the cortex and the hippocampus. Shogaol treatment improved BBB integrity. Results of the behavioral analysis showed that Shogaol treatment (2mg/kg & 12mg/kg) rescued behavioral impairment and improved anxiety and depression.

Conclusion: Shogaol treatment showed strong therapeutic potential in metals & HFD induced neuroinflammation and improved cognitive functions; thus, can be considered a potential drug candidate in the future.

Objectives: This article explores the possibilities of SERMs as effective BC agents.

Methods: A detailed literature survey of the history and recent advancements of SERMs has been carried out, taking BC as the primary target. This review provides information about ER structure, signaling, pharmacological action, chemical classification with SAR analysis, and benefits and adverse effects of SERMs as potential BC agents.

Results: Exhaustive literature studies suggested that SERMs having an agonistic, antagonistic or mixed activity to ER could efficiently inhibit BC cell proliferation.

Conclusion: Each chemical class of SERMs comprises some salient features and potentials, which may be further investigated to obtain novel effective SERMs in BC therapy.

Objective: This review will analyze the safety of intravenous infusion of MSCs and determine the incidence of any possible resultant Serious Adverse Events (SAEs).

Methods: Using PubMed, we searched the scientific literature to identify SAEs related to intravenous infusion of MSCs. We performed disease-specific searches and a general adverse event search.

Results: A total of 70 studies were included in this review. Thousands of infusions were administered and only two SAEs were identified from the same study. The SAEs were two upper extremity thromboembolisms in patients with preexisting renal disease.

Conclusion: Properly performed intravenous infusion of MSCs is very safe, with a near absence of reported serious adverse events associated with its use.

Objective: The study aimed to improve the therapeutic efficacy and minimize the toxic effects of irinotecan by developing a fullerene functionalized biotin drug delivery system and adsorbing irinotecan on the surface of the functionalized fullerene-biotin complex.

Methods: Fullerene (C₆₀) has been observed as a potential drug delivery agent and the aminefunctionalized C₆₀-NH₂ was synthesized by functionalizing ethylenediamine on the surface of C₆₀. The PEI functionalized C₆₀ was further synthesized by polymerization of aziridine on the surface of C₆₀- NH2. Biotin was attached by an amide linkage to C₆₀-PEI and the anti-colon cancer drug irinotecan (IRI) was encapsulated (C₆₀-PEI-Biotin/IRI). The C₆₀-PEI-Biotin/IRI was characterized and evaluated for in vivo anti-colon cancer activity in rats and the results were compared with the parent drug irinotecan.

Results: The results showed that C₆₀-PEI-Biotin/IRI conjugate had a controlled release profile according to in vitro HPLC studies. Moreover in vivo anti-tumor studies suggested that the conjugate proved to be less toxic to vital organs and had high efficacy towards tumor cells. Statistical studies confirmed less tumor index and tumor burden in the case of conjugate when compared to irinotecan.

Conclusion: It is hypothesized that the conjugate (C₆₀-PEI-Biotin/IRI) could cross the cell membrane easily through overexpressed biotin receptors on the cell surface of colon cancer cells and showed better efficacy and less toxicity in comparison to IRI in the colon cancer rat model.

Objective: Literature survey of neurodegenerative diseases and immunotherapeutic approaches is used to evaluate their pharmacological effects and future endeavours.

Methods: A literature search was performed to find the relevant articles related to neurodegenerative diseases and immunotherapies. Clinical trials data were analysed from clinicaltrial.com.

Results: According to the literature study, it was found that researchers have explored the effect of active and passive vaccines generated against amyloid-β, tau, α-synuclein and mHTT. Few clinical trials have shown severe side effects and terminated, despite that, few of them produced desirable effects for the treatment of AD and PD.

Conclusion: Several immunotherapeutic trials have shown promising outcomes against amyloid-β, tau and α-synuclein. In addition, various preclinical studies against mHTT and prion proteins are under scrutinization. These clinical outcomes indicate a promising role of immunotherapies against neurodegenerative diseases.

Methods: Three extracts of Solidago virgaurea were prepared, and their antidiabetic potentials were evaluated by various cell-free, cell-based, and in vivo studies.

Results: We found that the Solidago virgaurea contained multiple bioactive phytochemicals based on the GC-MS analysis. The Solidago virgaurea extracts effectively inhibited the functions of the carbohydrate digestive enzyme (α-glucosidase) and protein tyrosine phosphatase 1B (PTP1B), as well as decreased the amount of advanced glycation end products (AGEs). In the L6 myotubes, the Solidago virgaurea methanolic extract remarkably enhanced the glucose uptake via the upregulation of glucose transporter type 4 (GLUT4). The extract also significantly downregulated the expression of PTP1B. In the streptozotocin-nicotinamide induced diabetic mice, the daily intraperitoneal injection of 100 mg/kg Solidago virgaurea methanolic extract for 24 days, substantially lowered the postprandial blood glucose level with no obvious toxicity. The extract’s anti-hyperglycemic effect was comparable to that of the glibenclamide treatment.

Conclusion: Our findings suggested that the Solidago virgaurea extract might have great potential in the prevention and treatment of diabetes.

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.

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.

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.

Objective: In our work, we have highlighted two new strategies, nicorandil and Bone marrow-derived mesenchymal stem cells (BM-MSCs), as effective in reversing renal fibrosis induced by partial unilateral ureteral obstruction (PUUO).

Methods: The current study included 96 male albino rats randomly divided into four groups, with 24 rats per group; Group I, the control group; Group II, PUUO, where two-thirds of the left ureter was entrenched in the psoas muscle; Group III, same surgical procedure as in Group II for 7 days, and then the rats received 15 mg/kg/day nicorandil once daily for 21 days; and Group IV, same surgical procedure as in Group II for 7 days, and then rats were given 3 × 106 of labeled MSCs injected intravenous, and left for 21 days. Blood and kidney tissues were collected for biochemical, histological, and molecular analyses.

Results: Both the nicorandil and BM-MSCs treatment groups could ameliorate kidney damage evidenced by inhibition of MDA elevation and total antioxidant capacity reduction caused by PUUO. Also, there was a significant reduction observed in TNF, TGF, IL6, collagen I, and α-SMA in addition to improvement in histological examination. However, a significant difference was found between the BM-MSCs and nicorandil-treated groups.

Conclusion: Our results suggest that BM-MSCs and nicorandil improved renal fibrosis progression through their antiapoptotic, anti-inflammatory, and antifibrotic effects in male albino rats subjected to PUUO, with BM-MSCs being more effective compared to nicorandil.
