Quercetin and Its Derivatives: Therapeutic Potential in Combating Inflammation and Oxidative Stress for Enhanced Diabetic Wound Healing

2026-05-09

Diabetic wounds are characterized by delayed healing due to chronic inflammation and oxidative stress, driven by elevated pro-inflammatory cytokines like TNF-α, IL-1β, and IL- 6, and excessive Reactive Oxygen Species (ROS). These disrupt key processes such as angiogenesis and collagen synthesis, essential for wound repair. Quercetin, a natural flavonoid, has demonstrated potent anti-inflammatory and antioxidant properties, making it a promising therapeutic for diabetic wound management. It inhibits NF-κB signalling, reducing inflammatory mediators, while boosting antioxidant enzymes like Superoxide Dismutase (SOD) and Catalase (CAT), thereby mitigating oxidative stress. Quercetin also enhances fibroblast and keratinocyte proliferation and promotes extracellular matrix deposition, crucial for tissue repair. Recent advancements in nanocarrier systems, including liposomes and hydrogels, have improved quercetin’s bioavailability and targeted delivery to wounds, increasing its efficacy. Future research should focus on refining delivery methods and conducting comprehensive clinical trials to establish quercetin's clinical utility. Despite these challenges, quercetin offers significant potential as a natural agent in promoting diabetic wound healing by targeting inflammation and oxidative stress.

A Comprehensive Review of Acne: Pathogenesis, Etiology, Treatment Approaches, and Recent Developments

2026-05-09

Introduction: Acne vulgaris is a prevalent chronic inflammatory condition of the pilosebaceous units, primarily affecting adolescents. It arises from a multifactorial interplay of genetic, hormonal, microbial, and environmental factors. Besides physical manifestations, acne significantly impacts mental health, contributing to anxiety, depression, and low self-esteem. Conventional therapies are often limited by poor skin penetration, drug resistance, and undesirable side effects, highlighting the need for more effective treatment approaches.

Methods: A systematic literature review was conducted according to PRISMA guidelines. Articles published between 2013 and 2023 were retrieved from PubMed, Scopus, and Web of Science using keywords such as “acne pathogenesis,” “acne treatment,” “nanocarriers,” and “drug delivery systems.” After duplicate removal and screening of titles and abstracts, relevant full-text articles were analyzed. Additionally, ongoing clinical trials and patents were reviewed to understand current and emerging therapeutic strategies.

Results: Acne development involves four core factors: increased sebum production, follicular hyperkeratinization, Cutibacterium acnes colonization, and inflammation. Nanocarrier-based systems–liposomes, niosomes, ethosomes, SLNs, NLCs, transfersomes, and nanoemulsions have demonstrated improved drug delivery in acne treatment. These systems enhance dermal penetration, control drug release, improve bioavailability, and reduce side effects.

Discussion: Nanocarrier systems address critical limitations of conventional acne therapies, offering improved efficacy and patient adherence. However, issues like high production costs, formulation complexity, and limited long-term safety data remain. Continued preclinical and clinical research is essential.

Conclusion: Nanomedicine offers a promising future for acne management by enhancing drug delivery and minimizing side effects. With further innovation and validation, these systems may revolutionize dermatological treatment practices.

Phytotherapeutic Potential of Rosemary in Hair Growth and Hair Fall Prevention: Mechanisms, Efficacy, and Future Perspectives

2026-05-09

Thinning and hair loss, especially when linked to androgenetic alopecia (AGA), pose significant psychological and clinical challenges. Conventional treatments often have limitations, including side effects and inconsistent results. This paper focuses on the medicinal potential of rosemary (Rosmarinus officinalis) in preventing hair loss and promoting hair growth. It integrates the basic biology of hair, the dynamics of the hair growth cycle, and the underlying causes of hair loss. In addition to examining the plant's botanical origin, traditional uses, and chemical profile, the review highlights the bioactive components of rosemary, including 1,8-cineole, rosmarinic acid, and carnosic acid. These compounds possess multiple beneficial properties, such as enhanced microcapillary circulation, inhibition of testosterone 5α-reductase, and antibacterial, antiinflammatory, and antioxidant effects. Collectively, these characteristics support a healthier scalp and promote hair follicle renewal. Despite promising results from preclinical and clinical studies, challenges such as small sample sizes, inconsistent formulations, and a lack of long-term safety data remain. Future research should focus on standardizing extraction and formulation methods and conducting large-scale, long-term clinical trials to fully elucidate rosemary's therapeutic potential for hair restoration.
