This study found that serum 3 alpha-Adiol-G levels in men are significantly associated with chest hair density and acne, indicating its role in reflecting androgen activity in peripheral tissues.

This study observed that in vitro exposure to dihydrotestosterone worsened COVID-19 spike protein-induced endothelial injury, while spironolactone showed potential in reducing this effect, suggesting a rationale for further evaluation in treating COVID-19.

This review found that patients with depression generally have higher hair cortisol concentrations compared to healthy controls, while those with PTSD tend to have lower concentrations.

In this study, researchers found that tritiated cortisol was incorporated into the hair of rhesus monkeys primarily as cortisol and cortisone, as well as other metabolites, after systemic administration.

This study found that polymeric micelle formulations significantly improved the targeted delivery of adapalene to hair follicles compared to standard Differin® products, which suggests potential advantages in treating hair follicle-related conditions and reducing side effects.

This study found that hair cortisol levels increase and testosterone levels decrease with obesity, suggesting that measuring hormones in hair may be a valuable tool in obesity research and clinical practice.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This study identified a missense mutation in the rat Desmoglein 4 gene, causing abnormal hair shaft development in lanceolate hair mutant rats by disrupting a critical calcium binding site.

This study found that a combination therapy of Diane 35 with finasteride was more effective at reducing hirsutism scores in women with idiopathic hirsutism or polycystic ovary syndrome after 3 months compared to Diane 35 alone.

Insulin resistance linked to obesity may increase COVID-19 severity.

This study found that a novel skin patch combining extracellular matrix and ciprofloxacin promotes advanced wound healing and skin regeneration in mouse models of infected wounds.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

This article examines differences in aging among ethnic populations and highlights cosmetic procedures specific to skin of color, but reports no new research findings.

This study suggests that artificial sebum L may serve as an effective substitute for human sebum in drug transport studies, due to its similar physicochemical properties.

This study developed a hydrogel from glycol chitosan and silica nanoparticles, which showed promise in wound healing by supporting microvessel and hair follicle growth in skin defects.
