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.

This study developed a high-throughput method that identifies bioactive chemicals influencing DHT production in prostate cancer cells, with potential nutraceutical candidates including fucoxanthin, phenethyl caffeate, and Curcuma longa L. extract.

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

This study developed methods for detecting carboxy-finasteride in urine for doping control, demonstrating detection up to 49 hours post-administration with high precision and accuracy.

A cheap stainless steel container from a retail store can store liquid nitrogen effectively for 8-12 hours, saving money for medical practitioners.

A liquid protein diet caused hair loss in a young woman.

This study found that the polyherbal gel formulations F4 and F6 demonstrated superior in vitro performance in hair care, showing promise as cosmeceutical candidates, although further in vivo and clinical studies are necessary to confirm their efficacy and safety.

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.

In this randomized controlled trial at Bolan Medical Complex Hospital, researchers observed that liquid nitrogen cryotherapy increased hair regrowth by 60% in alopecia areata patients, significantly outperforming alternative treatments, which achieved 40% regrowth.
