This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This review discusses the safety of testosterone therapy for postmenopausal women and concludes that, aside from hirsutism and acne, it appears safe at physiological doses for several years, though more long-term studies are needed.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

This review examines medical literature on postfinasteride syndrome and reports no new results; the authors call for more controlled studies on permanent sexual dysfunction and mood changes linked to 5-alpha-reductase inhibitors.

This study suggests that gender-affirming testosterone therapy in transgender men is generally safe and effective with adequate screening and monitoring, although high-quality long-term studies are lacking.

The CSTAR registry, the largest in China for SLE, reports more than 25,000 patients registered since 2009, detailing demographics, clinical characteristics, and providing data for future studies.

This review discusses the potential use of platelet-rich plasma for treating alopecia areata but reports no new experimental findings, noting the need for standardized protocols and larger studies to evaluate its efficacy.

In this review, researchers summarize the methods for characterizing telocytes, outline their physiological roles and implications in diseases, and discuss potential future studies including precise markers and targeted therapies.

In this review, the authors summarized the neuroprotective role of water- and fat-soluble vitamins in neurodegenerative diseases, highlighting their potential preventive and therapeutic effects through antioxidant and anti-inflammatory properties while acknowledging some studies question their preventive influence.

This study on Alzheimer's patients found that chronic sodium selenate treatment (up to 23 months) was safe and well-tolerated, with most adverse events being mild, and suggested potential slowing of cognitive decline, though confirmation requires further controlled studies.

In this study, despite most patients recognizing alopecia areata as serious and adhering to treatment, psychological well-being remained adversely affected by the disease, highlighting the need for larger studies to better address these psychological impacts.

This study observed that gold thread implantation increased hair regrowth in both human patients and mice, suggesting it could be an effective hair regrowth treatment, although further studies are needed to understand its mechanisms and safety.

This chapter reviews the roles of ethylene and auxin in seedling growth and development and reports no new experimental results; it highlights recent studies on their mechanistic crosstalk.

This study conducted at a Moroccan tertiary dermatology center describes the characteristics of pediatric lichen, highlighting that dermoscopy can improve diagnostic accuracy by identifying distinct patterns across clinical variants, with lichen sclerosus being the most frequent subtype among the children studied.

This review discusses the potential impact of lifestyle factors on the progression of androgenetic alopecia and reports no new clinical findings; the authors emphasize the need for more comprehensive studies.

In this study, male patients treated with 150 mCi of radioactive iodine showed no negative impact on fertility, but long-term studies with larger groups are needed to further assess hormonal effects and sperm health after this treatment.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

In this retrospective study conducted at a dermatology institute in Mexico, researchers analyzed 1,888 adult alopecia cases, identifying alopecia areata as the most common type. The study underscores the importance of regional studies to better understand alopecia patterns and inform management strategies.

This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

This review examines the evidence on nutritional and herbal supplements for women's health, emphasizing the need for more long-term studies to develop evidence-based guidelines for personalized supplementation.

This meta-analysis reported no significant differences in vocal alterations and quality of life between women with PCOS and control groups, yet emphasized that the findings are limited by a lack of high-quality studies, suggesting further research is needed.

This review discusses the potential role of Garudan kizhangu ennai, a polyherbal Siddha formulation, in managing alopecia areata and highlights its various pharmacological properties, although further clinical studies are needed to confirm its efficacy.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This review discusses the potential role of the dietary antioxidant index in reducing the risk of various diseases, including obesity-related conditions, certain cancers, osteoporosis, and mental illnesses, but calls for further studies to confirm these findings.

This systematic review reported that probiotics, prebiotics, synbiotics, postbiotics, and dietary supplements may improve hair density and reduce dandruff severity in individuals with scalp disorders, potentially by modifying inflammation, oxidative stress, and microbiota composition; however, variability across studies limits the strength of these conclusions.
