This study describes a fast LC/MS/MS method for detecting various synthetic drugs in urine, meeting World Anti-Doping Agency performance limits.

This study suggests that finasteride-loaded liquid crystalline nanoparticles could be a viable alternative to oral administration for treating androgenetic alopecia due to their controlled release and skin permeation properties.

Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

This study found that liquid crystalline nanoparticles formulated with Cremophor surfactants significantly enhanced skin permeation of finasteride compared to lower surfactant concentrations.

This study found that coating liquid crystalline nanoparticles with chitosan significantly enhanced the skin permeation of 5α-reductase inhibitors, suggesting a promising strategy for improving topical delivery in androgenetic alopecia treatment.

This study developed a novel method to simultaneously measure finasteride, dutasteride, and related biomarkers in serum, finding that both drugs lowered DHT levels while increasing substrate concentrations.

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

This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.

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

The researchers reported that both cryotherapy and betamethasone lotion yielded similar improvement rates for alopecia areata patches, without complete recovery observed in any patient.

This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

This study developed and validated a reliable method to measure finasteride levels in human plasma, which was successfully used to assess its pharmacokinetics after a 5 mg dose in healthy volunteers.

This case report describes subcutaneous emphysema in a patient's forearm as a rare complication of liquid nitrogen spray used on hypertrophic actinic keratosis, resolving spontaneously within a day.

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 developed a method using LC/APCI-MS to measure the activity of steroid 5α-reductase, applied to kinetic studies and inhibitory tests with Finasteride in a rat prostatic enzyme model.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

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.

Validated method reliably measures finasteride in tablets using liquid chromatography.

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 study found that both fractional CO2 laser and cryotherapy were effective and safe treatments for alopecia areata, with the CO2 laser showing somewhat better 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 identified the major component of katuk leaf water extract as an alkaloid compound with a molecular mass of 406.3131 m/z, named (S, S)-5,5′-amino-4,4′-dihexyl-propyldihydropyrazol-3,3′-one.

This study found that freezing nitrogen ethanol composite (FNEC) caused less cryoablative damage to surrounding normal tissue than liquid nitrogen in a mouse model of human bone xenograft transplantation.

This study reported that a liquid-liquid extraction method using methyl tert-butyl ether and methylene chloride was most effective for extracting dutasteride and its internal standard from rat plasma.

This study found that improved testosterone measurement using LC-MS/MS in women with PCOS revealed a stronger correlation between hyperandrogenism and insulin resistance than previously detected.

Among young rats, this study found that a liquid protein diet significantly affects body condition but has minimal impact on gingival collagen metabolism.

This study successfully established and validated a method using LC-MS/MS to measure multiple androgens in plasma, finding that individuals with acne had higher levels of certain androgens compared to those with obesity.

This study found that higher levels of dihydrotestosterone in the parietal region of the scalp may correlate with the clinical presentation of androgenetic alopecia.

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.
