This study found that the proposed LC-MS/MS method accurately quantified the drug content in split tablets of finasteride and terbinafine, revealing significant variability and suggesting that non-scored tablets should not be split.

This study found that after application of a testosterone cream containing 17α-methyltestosterone and testosterone propionate, these compounds could be detected in dried blood spots up to 97 hours post-application, potentially leading to sample contamination during fingertip puncture.

This study observed that DDAIP-HCl enhanced the permeation of minoxidil through human cadaver skin, suggesting potential for improved treatment efficacy in male pattern hair loss.

Researchers developed a quick and sensitive way to measure finasteride in blood using a small sample size.

This study comparatively evaluated different extraction techniques for Schinus terebinthifolius Raddi leaf extracts and found that conventional extraction with ethanol yielded the highest antioxidant activity and beneficial effects on skin cell viability, supporting its potential use in sustainable cosmeceutical formulations targeting skin aging.

This study identified 674 differentially expressed proteins in the skin tissues of male and female Chinese merino sheep, suggesting gender-specific molecular mechanisms that may affect wool traits.

This study found that while dutasteride significantly altered pregnane metabolism in mares during late gestation, it did not impact pregnancy outcomes, highlighting the complexity of pregnane metabolism and the necessity of LC-MS/MS for accurate measurement.

This study suggests that chest, arm, leg, and beard hair samples may be viable alternatives to scalp hair for monitoring long-term alcohol intake, although body hair is more typically collected from men.

This study developed a sensitive HPLC-MS/MS method for determining cyproterone acetate levels in human plasma and found no significant difference in its concentration between two oral formulations in bioequivalence testing.

This study developed and validated a method for measuring stress biomarkers in hair during pregnancy, finding that glucocorticoid levels increased over trimesters while endocannabinoid levels remained constant, suggesting hair analysis as a reliable tool for monitoring stress responses in pregnant women.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

In this case study, authors reported that a 43-year-old female patient initially showed persistently high testosterone levels due to immunoassay interference, later verified as normal using liquid chromatography-tandem mass spectrometry (LC-MS/MS), highlighting the need to consider assay artifacts in diagnosing hyperandrogenism without clinical signs.

This study evaluated the anti-alopecia effects of Petroselinum crispum leaf extracts in a rabbit model and through molecular docking analysis, finding that two ethyl acetate fractions promoted hair growth, with effects comparable to minoxidil, suggesting potential for alopecia treatment development.

This study found that various plant oils can penetrate the lipid-rich cell membrane complex of hair, improving its fatigue strength by preventing flaw propagation, with greater penetration observed for oils containing shorter chain lengths and unsaturated fatty acids.

This study found that androstenedione was more effective than testosterone in diagnosing hyperandrogenism in women with PCOS when measured by LC-MS/MS.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

This study developed a liquid chromatography with tandem mass spectrometry method to detect sex hormones in health supplements from Hanoi, Vietnam, finding three out of 16 samples contained sex hormones, including banned testosterone at low levels (~0.5 mg/kg).

This study reports that dutasteride, used alone or with tamsulosin, effectively reduces acute urine retention and surgery risk in men with benign prostatic hyperplasia, and may lower prostate cancer incidence, suggesting potential chemopreventive benefits.

This study observed that both finasteride and dutasteride significantly decreased dihydrotestosterone concentrations in hair, with dutasteride showing the greatest reduction.

This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.

This preliminary study of Alopecia Areata identified limited expression of certain metabolic transporters and enzymes in hair follicle immune cells, providing early insight into their unique energy needs.

This study concluded that the liquid chromatography-mass spectrometry method developed is viable for accurately quantifying spironolactone and its metabolite canrenone in plasma despite interference from plasma components.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This study developed a sensitive method using LC-ESI-MS/MS for accurate and reliable measurement of nine steroid hormones in children's serum.

In this study, L-cysteine treated with the Trivedi Effect® showed significantly increased isotopic abundance ratios, which may enhance its stability and shelf-life.

Researchers developed a method to identify and measure different animal hair fibers in textiles, successfully distinguishing materials like cashmere from cheaper fibers.

This study suggests that decreased levels of dihydroceramide in hair may serve as a biomarker for the progression of alopecia.

This study found low concordance between distal and proximal hair cortisol concentrations during early pregnancy, particularly when measured with different assay methods.
