This study developed a novel mouse model of catamenial epilepsy by manipulating neurosteroid levels and demonstrated that withdrawal increases seizure susceptibility, potentially linked to changes in GABAA receptor-subunit plasticity.

This study found that different decontamination protocols caused varying levels of cuticle damage in hair, with aqueous buffer treatment resulting in the most substantial degradation.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

This study found that DNMT1 promotes adipogenesis in hair follicle stem cells by regulating the miR-214-3p/MAPK1/p-ERK1/2 pathway, suggesting potential applications in stem cell therapy.

This study found that combining MSM with MAP significantly enhanced hair growth in mice, comparable to or better than minoxidil, due to increased intradermal retention of MAP.

This study developed a micellar electrokinetic capillary chromatography method for determining minoxidil in Rogaine and generic products, offering a simple and efficient alternative to HPLC.

Methylmercury accumulates in mouse hair during growth, then decreases when growth stops.

This study found that supplementing Liaoning cashmere goats with HMBi increased cashmere length while decreasing its diameter, attributed to changes in Met-related metabolites and elevated expression of genes related to the Met cycle and cell differentiation pathways such as Wnt and MAPK.

This study found that subcutaneous injection of medroxyprogesterone acetate was more effective than intramuscular or topical treatments in reducing hair diameter for hirsute females.

This study observed that while betaine supplementation decreases total homocysteine and increases methionine levels in a mouse model of CBS deficiency, it is not as effective as methionine restriction in reversing associated phenotypes.

This study reported the development of new pyrazole-based MPC inhibitors that effectively inhibit mitochondrial pyruvate transport, showing potential as therapeutic candidates for conditions like metabolic dysfunction-associated steatohepatitis without activating PPARγ.

This review discusses the use of anabolic-androgenic steroids in sports and outlines current methods for detecting urinary steroid doping, particularly testosterone, but reports no new experimental findings.

This study developed and validated a micellar electrokinetic chromatography method to determine finasteride stability, finding that the drug degrades under acidic, basic, and oxidative stress conditions.

In this study, α-MSH and cyclic AMP were found to stimulate melanogenesis in hair follicle cultures, while cyclic GMP and melatonin inhibited melanin production but not tyrosinase activity.

This study found that metyrapone and etomidate provide dose-dependent anticonvulsant effects against seizures, with delayed effectiveness linked to increased neurosteroid levels.

This source explains that unlike genetic hormonal alopecia, alopecia areata is associated with inflammatory factors and may also involve psychological and genetic contributions.

This case study describes a severe instance of iatrogenic Cushing's syndrome induced by gamma-hydroxybutyric acid, exacerbated by combined use of betamethasone and anabolic steroids, in an HIV-positive patient on cobicistat-containing therapy.

This study found that among bodybuilder-intended drugs from the black market, 33.8% of labeled products and 52.5% of steroidal oily solutions contained ingredients not matching their labels.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.

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 reported high analytical performance of an RMP for DHT quantification, with the ability to differentiate between 5α-DHT and 5β-DHT isomers, making it suitable for routine assay standardization and clinical sample evaluation.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.

In this report, an 18-year-old female with trichotillomania was successfully treated using the glutamate modulator n-acetylcysteine.

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.

This study found that in vitro heat straightening of hair reduced THC and cocaine concentrations but increased CBN and BZE levels, suggesting heat conversion of these substances.

This study reports that the metanephrine content was significantly higher in patients with alopecia areata compared to those without the condition.

This study developed a faster method for analyzing fatty acid ethyl esters in hair to help detect alcohol consumption levels, showing potential for applications in forensic and clinical settings.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

A girl's hair loss from a pharmacy error improved after getting the right medicine.

This review discusses the role of neuro(active)steroids, particularly those in the 5α reductase pathway, in modulating dopamine signaling and their impact on neuropsychiatric disorders characterized by dopamine imbalances, including addiction, schizophrenia, and Parkinson's Disease.
