This study examined the complex morphology of the cornified claw sheath in domesticated cats, uncovering structures and growth patterns that help maintain sharp claw tips essential for climbing and prey capture.

This review examines various androgen deprivation therapy methods for advanced prostate cancer, highlighting benefits and potential cardiovascular and sexual adverse effects, but reports no new clinical results.

This study found that α-MSH administration before skin wounding in adult mice reduced inflammation and scar area, suggesting a potential pathway to more regenerative healing.

In this study, constitutive expression of Del1 in mice did not affect wound healing but was associated with increased hair growth following anagen induction.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This review highlights the effectiveness of medicinal plants in treating symptoms of hair disorders, emphasizing their antifungal and antioxidant properties as supported by 23 selected studies.

The document explains how hair follicles develop, their structure, and how they grow.

This review discusses the development of electrospun nanofibrous scaffolds for promoting angiogenesis in tissue engineering but notes that their clinical application beyond bone and skin repair is still limited.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This review discusses the functions of SARS-CoV-2 non-structural proteins in facilitating immune evasion and highlights possible therapeutic strategies, reporting no new clinical results.

This study found that targeting SV40 T antigen expression to hair follicles in transgenic mice caused abnormal hair structure and hair loss, but did not lead to cell immortalization or tumor formation in follicles.

This study found that both dark and white dromedary camels exhibited high medullation in hair fibers, suggesting adaptations for insulation and heat dissipation in hot desert environments.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study identified four new genetic loci associated with acne risk and highlighted key pathways involved in its genetic predisposition, potentially explaining 9.4% of acne's phenotypic variance.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

African Americans lack knowledge about laser hair removal safety, Nd:Yag laser treatment is effective with high satisfaction, pressure during surgery can cause hair loss, and treating ovarian inflammation may help with alopecia areata.

This study found that prenatal exposure to finasteride in rats disrupted male reproductive development, causing physical alterations such as delayed preputial separation and increased nipple retention.

Runx1 is crucial for proper hair structure and development.

This review discusses how ionizing radiation causes skin damage by inducing cellular senescence in keratinocytes, which secrete inflammatory mediators, recruiting immune cells and exacerbating inflammation, impacting the skin barrier function and healing.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study characterized the CYP154C7 enzyme from *Streptomyces* sp. PAMC26508, highlighting its ability to hydroxylate steroids efficiently, particularly androstenedione, and identified key amino acids important for substrate selectivity and catalytic efficiency.

This study found that the MTCK, a masturbation aid, significantly improved intravaginal ejaculation latency time and some related sexual function scores in men with premature ejaculation after 8 weeks of use.

This review discusses current strategies and materials in tissue engineering for skin regeneration, emphasizing design approaches and suggesting directions for future research; it reports no new clinical findings.

In this review, the authors emphasize the importance of understanding drug chemical structures to help general physicians better manage and treat acne, although no specific results are reported.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

In this study, maternal exposure to constant light significantly altered the neonatal skin structure in rabbits, associated with reduced maternal melatonin levels.

In this study, researchers developed vegan exosome-like vesicles from microalgae that mimic mammalian exosomes, demonstrating promising in vitro, ex vivo, and clinical effects such as improved wrinkle depth and elasticity, making them a potential alternative in cosmetic applications.

This study examined the evolutionary and functional homology of steroid 5α-reductase and DET2 proteins, identifying protists as a common ancestor, and discovered a new subclass DET2-like in plants, potentially involved in polyprenol reduction.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.
