This study found that dutasteride increased scalp hair growth in men with male pattern hair loss, particularly at a 2.5 mg dose, and was more effective than finasteride over 24 weeks.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

Keratins are crucial for cell structure, growth, and disease risk.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This study reported that women with polycystic ovary syndrome had a higher prevalence of impaired glucose tolerance and type 2 diabetes, with variations influenced by ethnicity and obesity.

In this study, biotinidase deficiency in children usually presented with neurological or skin symptoms, while metabolic ketoacidosis and organic aciduria appeared later.

This review discusses the role of jumonji family proteins in chromatin regulation and development, highlighting their involvement in transcriptional repression and histone demethylation, but reports no new experimental findings.

This study found that both genetic and environmental factors influence appearance-related aging in women, with skin wrinkling, hair graying, and sun damage significantly affecting perceived age more than chronological age.

This article discusses the cutaneous side effects of various chemotherapeutic agents but reports no new clinical results; the authors emphasize the importance of dermatologists recognizing drug-induced skin reactions to better patient care.

In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

This study found that specific ATP-competitive TOR inhibitors (asTORis) decrease root growth in Arabidopsis thaliana in a dose-dependent manner, similar to their effects on mammalian cells.

This article reviews methotrexate's pharmacokinetics and toxicity, emphasizing the role of urinary excretion and leucovorin in avoiding most toxic reactions; it provides no new clinical results.

Some drugs can cause hair loss or increase hair growth, but these effects are usually reversible when the drug is stopped.

This review discusses the creation of transgender-specific guidelines by WPATH and the Endocrine Society, based mostly on clinical experience, and reports no new results.

This article outlines manifestations of systemic lupus erythematosus, noting rapid joint symptom improvement with corticosteroids and antimalarial drug responsiveness for skin symptoms, and links anti-Ro with photosensitive rash and subacute lupus.

This study found that blocking androgen receptors inhibits testicular descent in rats more effectively during the early stages of gubernacular outgrowth than inhibiting 5a-reductase.

This review discusses the cellular and molecular changes involved in cutaneous wound re-epithelialization and EMT, highlighting their similarities and differences, but reports no new clinical results.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

Male pattern hair loss could hint at androgens affecting COVID-19 severity.

This article reviews the complex pathophysiology of polycystic ovary syndrome, highlighting how genetic, hormonal, and environmental factors contribute to its diverse symptoms, and reports no new results.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.
