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

This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.

This report documents two cases of eruptive nevi occurring in the skin folds of children with Langerhans cell histiocytosis.

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 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 Bazhengsan significantly reduced inflammation and hyperplasia in male rats with nonbacterial prostatitis, indicating potential as a treatment for chronic prostatitis.

This study concluded that visits to emergency and urgent care centers for severe sunburn treatment are largely avoidable and contribute to significant healthcare costs.

This study found that mercury chloride administration in rats led to decreased intraepidermal nerve fibers and increased Langerhans cells, suggesting small nerve fiber damage after mercury poisoning.

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.

This article reviews the process for diagnosing polycystic ovary syndrome and suggests how it can be applied in clinical practice but reports no new results.

This study found that low-coverage whole-genome sequencing followed by imputation effectively identifies genetic variants associated with wool traits in Angora rabbits, offering a cost-efficient method for genetic research and breeding.

This study reports a novel diagnostic method for latent circadian rhythm sleep-wake disorder using circadian gene oscillations from hair follicle cells to improve sleep disorder differentiation and potential therapeutic intervention.

This study found that hair follicle mesenchymal stem cells improved liver function and pathology in a mouse model of liver cirrhosis, potentially by inhibiting the TGF-β/Smad pathway and reducing hepatic stellate cell activation.

This study found that bufotalinin, derived from Merremia peltata leaves, may enhance hair growth by acting as a potential androgen receptor antagonist in rabbits.

This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.

In this study, LC-OCT imaging was found to noninvasively identify specific features of cicatricial alopecia due to lupus erythematosus, such as hyperreflective collagen fibers, which may aid in distinguishing it from other types of scarring alopecia.

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 measuring certain steroids in hair can help diagnose and monitor congenital adrenal hyperplasia in Indonesian patients, offering a simple noninvasive method for developing countries.

This study found that for treating androgenetic alopecia, LC hair essence serum injections provided excellent results with fewer side effects compared to botulinum toxin A, which also showed significant efficacy but with higher associated costs and more frequent side effects.

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 reported that polyamine levels, especially N-acetyl polyamines, were higher in the vertex region of the scalp than in the occipital region in patients with male and female pattern hair loss.

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 method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

This study found that patients with alopecia areata had higher levels of oxidative stress markers and lower antioxidant enzyme activity compared to healthy controls.

This case report describes a 33-year-old woman with long-standing scalp issues and hair loss, revealing an unusual connection to past melanoma, but it presents no new research results.

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.

The two finasteride formulations are bioequivalent.
