research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
The study found that urine metabolites M1b or M4 are the best indicators of ATD use in horses, with detection possible up to 77 hours in urine and 28 hours in blood.
research Long-term detection of methyltestosterone (ab-) use by a yeast transactivation system
A yeast-based test can detect the steroid methyltestosterone in urine longer than traditional methods.
research External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to contamination, so they shouldn't be used alone to determine drug use.
research Separation of finasteride and analogues
Finasteride and analogues separated using LC-MS-MS technique.
research Enzyme-linked immunosorbent assays for doping control of 5α-reductase inhibitors finasteride and dutasteride

research Assessment of Multidimensional Health Care Parameters Among Adults in Japan for Developing a Virtual Human Generative Model: Protocol for a Cross-sectional Study
The study aims to create a model to predict health attributes using diverse health data from Japanese adults.
research Original article / Article original External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to external contamination, so they shouldn't be used alone to assess long-term drug use.
research Induction of hair follicle regeneration in mice ear by microencapsulated human hair dermal papilla cells
Microencapsulated human hair cells can regenerate hair follicles in mice ears.
research Intracrine androgen biosynthesis, metabolism and action revisited
The document concludes that blocking the internal pathways that create androgens might help treat cancers that depend on sex hormones.
research Circulating androgen regulation by androgen-catabolizing gut bacteria in male mouse gut
Gut bacteria can lower androgen levels in male mice.
research Rare and common genetic determinants of metabolic individuality and their effects on human health
Genetic variations greatly affect individual metabolism and can impact health and disease risk.
research 520 Body site heterogeneity and microbial diversity is lost in individuals with hidradenitis suppurativa
People with Hidradenitis Suppurativa have less diverse skin bacteria and different bacterial metabolism than healthy individuals.
research Clinical Case Seminar: Postmenopausal androgen excess-challenges in diagnostic work-up and management of ovarian thecosis
The conclusion is that removing both ovaries is the best treatment for excess male hormones in postmenopausal women, with medication as another option, and managing insulin resistance is important for diagnosis and treatment.
research The brain–gut–skin axis in inflammatory and disfiguring skin diseases: mechanistic insights, clinical correlations, and therapeutic strategies
Skin diseases like acne and psoriasis are linked to stress, gut health, and inflammation, with new treatments focusing on gut and mind-body approaches.
research Intermediate Hair Follicles from Patients with Female Pattern Hair Loss Are Associated with Nutrient Insufficiency and a Quiescent Metabolic Phenotype
Nutritional supplements may help improve hair growth in female pattern hair loss.
research Cutaneous Androgen Metabolism: Basic Research and Clinical Perspectives

research Clinical and Biochemical Parameters of Androgen Action in Normal Healthy CaucasianVersusChinese Subjects
Caucasian men have more chest hair and higher levels of certain androgen products than Chinese men.
research Assessment of Circulating Sex Steroid Levels in Prepubertal and Pubertal Boys and Girls by a Novel Ultrasensitive Gas Chromatography-Tandem Mass Spectrometry Method
Prepubertal girls have higher sex steroid levels than boys, possibly leading to earlier puberty.
research The Distribution of Estrogen Receptor β Is Distinct to That of Estrogen Receptor α and the Androgen Receptor in Human Skin and the Pilosebaceous Unit
Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).
