This study evaluated novel steroid compounds for their ability to inhibit 5α-reductase, showing that compound 16a significantly reduced rat prostate weight more than epristeride and exhibited excellent in vitro inhibitory potency, indicating its potential as a lead candidate for further benign prostatic hyperplasia drug research.

This study found that bis-benzylisoquinoline and Amaryllidaceae alkaloids, especially aromoline, show potential as antiviral agents, suggesting they could serve as foundations for developing new treatments against coronaviruses by enhancing the understanding of their structure-activity relationships.

This study found that 4-(4-Phenoxybenzoyl)benzoic acid derivatives may act as antioxidants by scavenging certain reactive oxygen species but exhibit prooxidant behavior under specific conditions.

In this study, researchers characterized a dehydroepiandrosterone hydroxylating enzyme system in hair follicles similar to the liver monooxygenase system, noting its inhibition by carbon monoxide and its dependence on NADPH.

Aldesleukin can treat certain cancers and increase HIV patient CD4+ counts but often causes severe side effects.

This study suggests that specific structural features of minoxidil analogs, such as hydrophobic and hydrogen bond field contributions, are key to enhancing lysyl hydroxylase inhibitory activity, which could inform future hair growth treatments.

This study found that chemically modifying human hair through esterification or disulfide reduction and alkylation affects the hair's viscoelastic properties, including stability, integrity, and response to moisture.

This study developed a faster method to analyze fatty acid ethyl esters in human hair, potentially distinguishing alcohol consumption levels more efficiently.

This study found that several synthesized pregnane derivatives exhibited significant inhibitory effects on testosterone conversion to dihydrotestosterone and reduced related androgenic parameters in multiple pharmacological models.

This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.

This study identified CYP3A4 as a key isozyme involved in the oxidative metabolism of finasteride in human liver microsomes.

This study identified 43 patients with psoriasiform skin reactions associated with Brazilian Keratin Treatment, suggesting this adverse effect may be underdiagnosed and important to recognize through clinical and dermatoscopic features.

This study found that chemical treatments like perming, dyeing, and bleaching significantly alter amino acids and lipids in human hair, which may impact hair strength and quality.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

A new compound was made that might help treat diseases related to male hormones.

This study used gas chromatography-mass spectrometry to simultaneously quantify androstenedione, dihydrotestosterone, dehydroepiandrosterone, testosterone, androsterone, etiocholanolone, progesterone, and pregnenolone in human hair, detecting differences in steroid concentrations between male and female samples.

This study found that 1,4-n-butylene dimaleate can restore the mechanical properties of reduced hair by reconnecting disulfide bonds and improving the hair's structural integrity using a thiol-Michael click reaction, compared to untreated reduced hair.

This study found that newly synthesized steroidal trienones demonstrated stronger 5α-reductase inhibitory activity compared to dienones in various biological models, suggesting potential for developing enhanced antiandrogenic drugs.

This review explores the potential role of pregnane neurosteroids in modulating alcohol withdrawal symptoms, suggesting a therapeutic target for treating alcohol dependence, but reports no new clinical results.

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 identified novel compounds as selective inhibitors of the type 1 isoenzyme of 5α-reductase, displaying promising potential for treating DHT-dependent disorders such as acne and androgenic alopecia.

Exposure to certain glycol ethers during pregnancy may be linked to lower verbal comprehension in children.

This study found that patients with alopecia areata had significantly higher levels of circulating DNA for certain cytokines compared to healthy controls, suggesting that increased circulating DNA may be linked to hair follicle damage in these patients.

This study found that ethanol-induced deficits in motor coordination in rats are not mediated by elevated neuroactive steroid biosynthesis.

This study identifies important differences in allergens found in hair products marketed for ethnic hair compared to nonethnic hair, with fragrances being the most common allergen in ethnic products.

This study determined that in axillary hair of mature males and females, free androgen steroids are primarily produced by sebaceous glands, while C19-steroid sulphates are products of sweat glands.

This study found that untargeted hair metabolomics analysis detected significantly altered endogenous biomolecules, potentially serving as biomarkers for identifying oxidative cosmetic hair treatments like bleaching.

This study found that "clean" shampoos are less likely to contain allergenic preservatives compared to traditional shampoos, but both types use fragrance equally, which can be irritating or allergenic.

Minoxidil can cause skin allergy; use alternative solvents or treatments if allergic.
