This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

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 suggests that metformin may be more effective than Dianette in treating moderate to severe hirsutism in women with PCOS, while also reducing markers of insulin resistance.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

These guidelines for alopecia areata management, prepared by the British Association of Dermatologists, provide evidence-based treatment recommendations and insights into the condition's epidemiology, diagnosis, and investigation.

This review discusses the psychological and social impacts of androgenetic alopecia and suggests that medical treatments can have some positive psychological effects, highlighting the condition's moderate stress and impact on body image.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

This review discusses the various common, rare, and unusual skin manifestations of lupus erythematosus and highlights the importance of accurate diagnosis, but it reports no new clinical results.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

In this study, the researchers did not confirm previously reported links between AGA and smoking or benign prostatic hypertrophy, but found potential associations with alcohol consumption and lean body mass at age 21 that merit further investigation.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

This article discusses the distinct skin findings associated with lupus erythematosus, noting that some are specific to lupus while others are nonspecific and occur with various diseases; it reports no new results.

This study found that Smad7 perturbs hair follicle development while promoting sebaceous gland formation by antagonizing Wnt/β-catenin signaling in transgenic mice.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

In this study, patients with generalized pustular psoriasis were classified into subgroups to better understand the disease's variability and assist in treatment selection, highlighting the role of localized infections in triggering flares.

This article reviews the scientific exploration of Ayurvedic medicinal plants and discusses their modern applications, such as a drug developed from Commiphora wightti for lipid disorders, without reporting new clinical findings.

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 study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

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.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

In this study, mycorrhizal fungal inoculation was associated with increased root-hair growth and enhanced drought tolerance in trifoliate orange by modulating auxin synthesis and transport under water stress conditions.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

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.

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.
