research Linking diet to acne metabolomics, inflammation, and comedogenesis: an update
Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.
research The control of hair growth: An overview
Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.
research Androgens in women
Androgens play a complex role in skin conditions like acne and hair loss in women, and normal blood levels don't always show true androgen status.
research The laboratory in the multidisciplinary diagnosis of differences or disorders of sex development (DSD)
Diagnosing sex development disorders requires combining medical history, physical exams, imaging, lab tests, and genetic data.
research Identification of Androgen-Inducible TGF-β1 Derived from Dermal Papilla Cells as a Key Mediator in Androgenetic Alopecia
TGF-β1 from dermal papilla cells suppresses hair growth, and targeting it may help treat androgenetic alopecia.
research PLASMA C19 STEROID SULPHATE LEVELS AND INDICES OF ANDROGEN BIOAVAILABILITY IN FEMALE PATTERN ANDROGENIC ALOPECIA
Women with female pattern hair loss have higher levels of certain androgens, suggesting increased androgen exposure to hair follicles.
research Brain allopregnanolone induces marked scratching behaviour in diet-induced atopic dermatitis mouse model
A brain-produced steroid causes increased scratching in mice with a skin condition similar to eczema.
research Non-clinical safety evaluation and risk assessment to human of aleglitazar, a dual PPAR α/γ agonist, and its major human metabolite
Aleglitazar and its major metabolite are safe enough to proceed to Phase 3 clinical trials.
research The Modulation of Aromatase and Estrogen Receptor Alpha in Cultured Human Dermal Papilla Cells by Dexamethasone: A Novel Mechanism for Selective Action of Estrogen via Estrogen Receptor Beta?
