Testosterone therapy improves strength and body composition in older men with low testosterone.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research Evaluation of Hair Density and Hair Diameter in the Adult Egyptian Population using Quantitative Trichoscopic Analysis
Trichoscopy is a quick, non-invasive way to measure hair density and thickness, helping diagnose hair loss.
research Phenotypic, transcriptomic, and genomic analyses reveal the spatiotemporal patterns and associated genes of coarse hair density in goats

research Rationale and design of the GLADE study: a randomized, multicenter, double-blind, placebo-controlled trial evaluating the safety and efficacy of gestrinone subdermal bioabsorbable pellet in endometriosis-related pelvic pain
Gestrinone pellets may help reduce pelvic pain in endometriosis safely.
research The Impact of Gender Affirming Hormone Therapy on Physical Performance
Gender-affirming hormone therapy improves physical performance in trans men to the level of cisgender men, while in trans women, it increases fat mass and decreases muscle mass, with no advantage in physical performance after 2 years.
research Gap junctions in Turing-type periodic feather pattern formation
Gap junctions help control feather pattern formation by enabling cell communication.
