This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This study supports the conclusion that the hormetic dose-response model is the most prevalent and fundamental model in biological and biomedical sciences, applicable to a wide range of clinical conditions.

This review discusses the historical development, mechanisms of action, and potential new clinical applications of the drug cepharanthine, highlighting its multi-faceted pharmacological properties; it reports no new clinical results.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This review discusses the role of the JAK-STAT pathway in autoimmune skin diseases and suggests potential therapeutic benefits of JAK inhibitors, but reports no new experimental results.

This review discusses the roles of androgens and androgen receptors in skin-related disorders and suggests that targeting androgen receptors may be a more effective treatment strategy.

This review discusses recent strategies targeting the neuroactive steroid biosynthetic pathway to enhance neurosteroidogenesis, highlighting their potential benefits for neurodegenerative and neuropsychiatric diseases, but reports no new clinical findings.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This study found that hair follicles in both mice and humans may serve as an important site for melatonin synthesis and signaling, potentially influencing hair cycle regulation by modulating keratinocyte apoptosis.

This review discusses evidence on androgen sensitivity as a potential factor in COVID-19 disease severity, suggesting that androgen receptor interactions could influence virus entry and progression, and reports no new clinical results.

This review examines the pharmacological evidence and bioactive compounds in Hibiscus plants, supporting their potential importance for developing treatments for chronic and degenerative diseases, though more research is needed.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

In this study, the researchers established a dose–response relationship between the hair follicle dose during cranial irradiation and the development of permanent alopecia, with other factors showing limited correlation.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This article suggests that modern lifestyle changes, including diet, stress, and chronic anti-inflammatory medication use, may disrupt the natural process of inflammation resolution, increasing vulnerability to chronic disease.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This review discusses the advancements in understanding and treating androgenetic alopecia and alopecia areata but reports no clinical findings; the authors emphasize the need for further research on molecular control mechanisms.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This systematic review concluded that the support for using spironolactone at commonly prescribed doses is based on evidence of limited quality.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This study found trilostane to be an effective and generally safe treatment for improving symptoms in dogs with pituitary-dependent hyperadrenocorticism.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

In this study, researchers identified novel LMNA mutations in patients with atypical progeroid syndrome, revealing clinical features distinct from other similar disorders, but unrelated to mutant prelamin A accumulation.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This review examines the dermatologic effects of tobacco use and nicotine, noting potential benefits and drawbacks for various skin conditions, but reports no new clinical results.

This review discusses various adverse drug reactions affecting the skin, hair, and nails, emphasizing the importance of recognizing and reporting these reactions but reports no new clinical findings.

This review suggests that understanding the biological and molecular reasons for more severe COVID-19 in men, particularly those at risk for prostate cancer, could improve management of these patients, but reports no new results.
