This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study found that finasteride treatment improved cardiac function and reduced heart failure progression in mice, suggesting it could be a potential therapy for pathological cardiac hypertrophy and dysfunction.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

Drug addicts often have scars, skin color changes, blocked veins, and bruising, with severe ulcers from barbiturate injections.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

This review highlights that idiopathic hirsutism is characterized by local hyperandrogenization affecting hair growth, without other signs of hyperandrogenism, and shows no new results; racial differences in prevalence are noted but not in androgenic steroids.

In this study, β-catenin overexpression in human hair outer root sheath cells increased the expression of Pitx2, which activated the follicular differentiation pathway, suggesting Pitx2's potential role as a modulator in hair growth control.

This review discusses the physiological changes in the female body during pregnancy, relating them to hormonal shifts, and comments on treatment considerations, but it presents no new research findings.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This review discusses the use of testosterone therapy for low libido in women, noting mixed evidence on breast cancer risk and a lack of long-term safety data.

This article discusses the emotional and psychological impact of severe alopecia areata on patients, emphasizing feelings of loss, vulnerability, and self-identity changes, and reports no new results.

This review discusses the roles and mechanisms of Wnt signaling in embryonic and adult stem cells and its association with cancers, and reports no new experimental findings.

This review discusses the variety of skin conditions linked to eating disorders and emphasizes that resolving these skin issues often requires treating the underlying disorder.

This review discusses the variability and limitations of treatments for severe alopecia areata, noting some patients may achieve cosmetic hair regrowth with treatment, while others experience persistent hair loss or relapse.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This review discusses various skin lesions associated with endocrinologic disorders such as Cushing's syndrome and adrenal insufficiency, and it reports no new clinical results.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This study found that women with common baldness treated with cyclical antiandrogen therapy for 52 weeks experienced increased hair density and a higher percentage of hairs in the anagen growth phase.

This review indicates that microneedle bipolar RF and fractional bipolar RF treatments offer significant improvement in acne scarring, with optimal results observed about three months after treatment.

This study found that newly synthesized steroidal trienones demonstrated stronger 5α-reductase inhibitory activity compared to dienones in various biological models, suggesting potential for developing enhanced antiandrogenic drugs.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

This article reviews the potential role of prolactin as a neuroendocrine modulator in skin biology and pathology, discussing its relevance for conditions such as psoriasis and hair growth, but reports no new clinical findings.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

This study found that using an antimicrobial lotion for 18 months may reduce inflammation and potentially partially reverse hair loss in men with androgenetic alopecia.

This study found that testosterone and 5α-dihydrotestosterone affect human sebocytes differently depending on the skin region, with spironolactone inhibiting their proliferation and counteracting androgen effects in facial sebocytes.
