In this study, researchers observed that in barn owls, the relationship between black feather spot size and testosterone levels varied by age and sex, suggesting involvement of genes regulating both traits rather than direct influence of testosterone on feather coloration.

This review discusses recent developments in α1-adrenoceptor antagonists and 5α-reductase inhibitors for treating benign prostatic hyperplasia, reporting no new clinical results while identifying potential areas for future drug development.

This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

This review summarizes current understanding and genetic insights into androgenetic alopecia, female pattern hair loss, and alopecia areata, noting the potential future role of molecular diagnostics, but it reports no new clinical results.

This chapter reviews the role of nanoparticles in wound healing, exploring current therapies, developments, and future directions, but reports no new clinical results.

In this animal study, the researchers found that Schisandra nigra extract may promote hair growth by extending the anagen phase and reducing TGF-beta2 expression.

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

This review explores the biomechanical factors and signaling systems, like Wnt, involved in the pathophysiology of psoriatic nail lesions and reports no new results.

This article discusses the early development of hair follicles with a focus on the formation of epidermal thickenings called placodes, reporting no new experimental results.

This review explores the potential link between psoriasis and metabolic syndrome, focusing on how disturbances in growth factors may connect these conditions and contribute to symptoms like keratinocyte proliferation and inflammation.

Gene therapy shows promise for improving wound healing, but more research is needed for human use.

This review discusses various treatments for adult acne in women, including topical, systemic, and alternative therapies, and reports no new clinical results.

This study found that euthyroid women with Hashimoto’s thyroiditis experienced less benefit from atorvastatin treatment in terms of cardiometabolic marker improvements compared to women with hypercholesterolemia but without thyroid issues, indicating a differential response in these populations.

This review discusses recent findings on pathogenic mechanisms, diagnostic criteria, and treatment options for PCOS but reports no new clinical results.

This analysis examines acne vulgaris using an integrative approach, highlighting its links with psychopathology, lifestyle, and diet, but reports no new results.

This research suggests that innate lymphoid cells type 1 (ILC1) may contribute to the development of alopecia areata, alongside CD8+ T cells, by disrupting hair follicle immune privilege and promoting features of the disease.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This article discusses the complex biological functions and social significance of hair follicles and reports no new research findings, emphasizing their role in health, disease, and a substantial beauty industry.

This review explores various tissue regeneration technologies, highlighting how skin substitutes have significantly improved healing success rates for burn injuries, and examines cell-based therapies aimed at reducing scar formation and improving burn management.

This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.

This article reviews TNF-α inhibitor-induced alopecia, identifying various types of hair loss such as severe alopecia areata and scarring alopecia, and calls for more controlled studies to better understand this adverse effect.

The authors suggest that male-pattern hair loss may be linked to neuropathy caused by tension on scalp nerves, potentially worsened by testosterone, and propose electrical stimulation as a temporary treatment.

This study found that primary stem cells from concentrated growth factor can differentiate into adipogenic, endothelial, and neuronal lineages in vitro, suggesting potential for use in regenerative therapies.

This review discusses the mechanisms and grading challenges of acne vulgaris, highlighting the need for better treatment strategies and reports no new experimental results.

Skin aging reflects overall body aging and can indicate internal health conditions.

This article discusses primary cicatricial alopecia, highlighting the need for early and precise diagnosis to effectively manage and treat these complex inflammatory hair disorders, but presents no new clinical results.

This study suggests that scalp massage may reduce stress, as indicated by decreased salivary cortisol and increased secretory immunoglobulin A, and improve comfort by reducing physical fatigue and negative emotions.

This review discusses the various determinants of hair quality in healthy individuals and reports no new clinical results; the authors emphasize the need for independent trials with standardized outcomes.

This report on a case of alopecia areata in a mother and daughter with a 16-year gap suggests genetic predisposition and environmental triggers rather than direct transmission.

In this study, genetic factors associated with hirsutism were identified, suggesting that both androgen-dependent and independent mechanisms may contribute to excessive hair growth in women.
