This study developed a sensitive and specific method for detecting testosterone in horse hair, finding trace amounts in samples for up to five months after administering a single dose.

This article reviews the characteristics, diagnosis, and management of premature adrenarche and suggests it may predict future ovarian hyperandrogenism in some adolescents; no new clinical results are reported.

This study identified trilauric glyceride and decanoylcarnitine as potential biomarkers for diagnosing PCOS in patients with and without insulin resistance, suggesting significant metabolic alterations in these conditions.

The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.

This study found that ethyl acetate extract from peanut stems demonstrated very strong antioxidant properties and moderate cytotoxic activity against MCF-7 cell lines in in-vitro and in-silico settings.

This study concluded that the formulated polyherbal shampoo is a chemical-free product with nourishing, conditioning, cleansing, and antimicrobial effects.

This study found that citrullinated proteins, which are implicated in rheumatoid arthritis, were abundant in outer membrane vesicles from Porphyromonas gingivalis but nearly absent in mutants, validating their approach to citrullinated peptide identification.

This study used micro-segmental hair analysis to identify the day of drug intake and suggested differing uptake mechanisms for co-administered drugs based on their properties.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

Detecting steroid esters in cattle hair is inconsistent and influenced by sampling factors.

In this study, transdermal application of anabolic steroids demonstrated rapid and extended detectability in urine, suggesting potential implications for doping control considerations.

This review discusses the challenges in measuring testosterone for assessing androgen excess in women and emphasizes the importance of quality control in laboratory methods, but it reports no new clinical results.

Cortisol and cortisone release from hair increases in steps over time during incubation.

This study found that the yeast androgen screen (YAS) could detect the activity of methyltestosterone in urine for a longer period than classical GC/MS, potentially identifying long-lasting metabolites.

This study found that hair shaft keratin proteins can be reliably identified from samples as small as 0.12 cm, suggesting their potential forensic utility with typical casework sample sizes.

This review discusses the evaluation of hyperandrogenemia in women and hypogonadism in men across different life stages and presents biomarkers used for diagnosing male hypogonadism, reporting no new clinical results.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study determined that a total testosterone concentration of ≥5.1 nmol/L identified androgen-producing tumors in women with severe hyperandrogenemia, while a lower threshold of ≥2.2 nmol/L was found for diagnosing pathologic hyperandrogenism in postmenopausal women.

This study found that a commonly-used DHT enzyme immunoassay shows significant cross-reactivity with testosterone, leading to inaccurate DHT measurements compared to a gold-standard LC–MS/MS method.

This study found that untargeted hair metabolomics analysis detected significantly altered endogenous biomolecules, potentially serving as biomarkers for identifying oxidative cosmetic hair treatments like bleaching.

In this study, researchers developed a method using scalp cyanoacrylate biopsy and advanced imaging techniques to effectively measure and visualize the distribution of anti-dandruff shampoo ingredients zinc pyrithione and climbazole within the scalp follicular infundibulum.

In this study, researchers found that human ovaries at different life stages biosynthesize both canonical and non-canonical steroid hormones, with fetal ovaries showing higher enzyme activity related to estradiol and testosterone conversion compared to adult tissues.

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.

This review discusses various chromatographic methods for analyzing finasteride in biological fluids and provides no clinical findings, focusing on detection techniques for different concentration levels.

This study used a newly validated method to find that one-year finasteride treatment resulted in no significant differences in urinary androgen and prostaglandin levels between male pattern baldness patients and normal controls.

This review examines the methods and challenges in androgen laboratory diagnostics, discussing their advantages, limitations, and evolution; it presents no new experimental results.

This study developed and validated a highly sensitive LC-MS/MS method for detecting multiple steroid hormones in urine and serum/plasma, demonstrating its potential for use in large-scale biomonitoring studies.

This study found that hair samples from chronic tramadol and cannabis users showed positive drug presence for 3-4 months and 6-7 months, respectively, after discontinuation.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.

This study developed a validated method using UPLC-MS/MS to analyze 37 hormones in human hair, enabling broader hormonal profiling for identifying endocrine disorders.
