22 citations
,
May 2006 in “Experimental and Clinical Endocrinology & Diabetes” This study found that calculated parameters like free testosterone and bioavailable testosterone were higher in women with hirsutism and PCOS compared to controls, suggesting these might better assess hyperandrogenemia than measured hormone values.

April 2010 in “Baillière's best practice and research in clinical endocrinology and metabolism/Baillière's best practice & research. Clinical endocrinology & metabolism” This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.
11 citations
,
June 1979 in “British Journal of Dermatology” This study found that the dehydroepiandrosterone hydroxylating enzyme system in hair follicles is similar to the liver monooxygenase system, sharing characteristics such as inhibition by carbon monoxide and dependency on NADPH.
11 citations
,
May 1996 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” This study reported that 5 alpha-reductase type 2 is the predominant enzyme in pubic skin fibroblasts across normal men, women, and hirsute patients, suggesting potential treatment options for idiopathic hirsutism.
13 citations
,
January 1997 in “Biochemical Pharmacology” This study found that human liver dehydroepiandrosterone sulfotransferase (DHEA ST) catalyzes the sulfate conjugation of minoxidil, indicating another pathway contributing to its metabolism in humans.
March 2024 in “Cell communication and signaling” This study found that sleep deprivation in mice can trigger prostatitis by activating the cGAS-STING pathway due to reduced levels of dihydrotestosterone and melatonin, resulting in a pro-inflammatory environment, while recovery sleep can mitigate these effects.
11 citations
,
September 2020 in “Steroids” This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.
May 2021 in “Journal of the Endocrine Society” This study found that while 11-oxyandrogens do not aid in diagnosing PCOS, they correlate with hirsutism severity, and 11-ketotestosterone levels decrease with combined oral contraceptive therapy.
June 2026 in “ACS Applied Materials & Interfaces” In this study, carbon dots derived from dandelion herb demonstrated significant antibacterial and biofilm-disrupting capabilities, promoting wound healing in a mouse model infected with S. aureus, while also showing excellent biocompatibility and the ability to modulate reactive oxygen species.
1 citations
,
May 2025 in “Analytical Science Advances” This study presented a new method for accurately measuring Fe3+ in small serum samples, achieving high recovery rates and agreement with established testing methods, while offering advantages such as cost-effectiveness, simplicity, and enhanced sensitivity.
March 2019 in “Reactions Weekly”
December 2024 in “Journal of Clinical Research in Pediatric Endocrinology” This study explains that congenital adrenal hyperplasia due to 21-hydroxylase deficiency presents as a continuous phenotype and involves symptoms ranging from virilization to accelerated growth in children, with diagnosis relying on clinical, biochemical, and genetic evaluation.
57 citations
,
May 1986 in “Clinics in endocrinology and metabolism” This review found that women with idiopathic hirsutism may have increased 5α-reductase activity, as indicated by elevated levels of a dihydrotestosterone-reduced metabolite, but more research is needed to confirm its clinical relevance as a biomarker.
19 citations
,
June 1999 in “Steroids” This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.
