research Hormonal Influences on Women's Health and Athletic Performance: Insights into the Menstrual Cycle, Menopause, Contraception, and Anabolic Steroids
Hormonal balance is vital for women's health and performance, but therapies like contraceptives and steroids have both benefits and risks.
research The human gut chemical landscape predicts microbe-mediated biotransformation of foods and drugs
The study developed a tool to predict how gut microbes process foods and drugs, showing that similar compounds often share metabolic pathways and effects.
research Metabolic and pathologic profiles of human LSS deficiency recapitulated in mice
Mice with LSS deficiency showed hair loss and cataracts, similar to humans, and can help in understanding and treating this condition.
research The Effect of Simvastatin on Plasma Steroid Hormone Levels in Metformin-Treated Women with Non-Classic Congenital Adrenal Hyperplasia
Simvastatin may help manage symptoms in women with non-classic congenital adrenal hyperplasia by lowering cholesterol and certain hormone levels.
research Nonsteroidal inhibitors of human type I steroid 5-.alpha.-reductase
New compounds called benzoquinolinones may treat conditions linked to excess DHT.
research Urinary 5-ene-steroid excretion in non-classical congenital adrenal hyperplasia due to 3β-hydroxysteroid dehydrogenase deficiency (NC-3BHSD)
Some women with excess hair growth have a hormone condition that can't be diagnosed by blood or urine tests alone.
research Vitamin D, Lipid Metabolism and Prostate Cancer
Vitamin D may help regulate cholesterol and influence prostate cancer development.
research Epidermal retinol dehydrogenases cyclically regulate stem cell markers and clock genes and influence hair composition
Enzymes involved in Vitamin A metabolism affect hair growth and type in mice.
research Genetic basis of polycystic ovary syndrome
The document concludes that PCOS has a strong genetic component, but more research is needed to fully understand the specific genes involved.
research Intracrine Testosterone Activation in Human Pancreatic β-Cells Stimulates Insulin Secretion
Testosterone helps human pancreatic cells increase insulin release.
research 5α-Reductases in Human Physiology: An Unfolding Story
Enzymes called 5α-reductases have many body functions and need more research to safely use inhibitors.
research Normal Pubertal Development in Daughters of Women With PCOS: A Controlled Study
Daughters of women with PCOS generally experience normal puberty but may have more body hair and different body fat distribution.
research Structural basis for the catalysis and inhibition of human steroid 5α‐reductase 2
The research gives new understanding on how human steroid 5α-reductases work and how drugs like finasteride inhibit them, which could help in creating new drugs.
research 17-Hydroxyprogesterone Responses to Gonadotropin-Releasing Hormone Disclose Distinct Phenotypes of Functional Ovarian Hyperandrogenism and Polycystic Ovary Syndrome
The research found that polycystic ovary syndrome (PCOS) has two distinct types, with one having more severe hormone and insulin issues.
research Human type 3 5α-reductase is expressed in peripheral tissues at higher levels than types 1 and 2 and its activity is potently inhibited by finasteride and dutasteride
Type 3 5α-reductase is more common and finasteride and dutasteride strongly inhibit it.
research Influence of estrogens on the androgen metabolism in different subunits of human hair follicles.
Estrogens can reduce DHT production in hair follicles, but are less effective than finasteride and progesterone.
research High-performance liquid chromatographic determination of the enantiomers of the benzoquinolinone LY 191704, a human type 1 5α-reductase inhibitor, in plasma
Researchers developed a method to measure different forms of a drug that could help treat prostate issues and hair loss, and found how these forms behave in animals.
research Androgenetic alopecia: An autosomal dominant disorder
Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.
