This study found that carbon nanotube impurities induced immunological toxicity in mice, whereas purified nanotubes showed good biocompatibility, suggesting high-temperature thermal treatment may improve nanotube biocompatibility.

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.

In this study, researchers found that human scalp hair, particularly when unwashed, can significantly react with ozone, reducing personal ozone exposure and increasing exposure to volatile reaction products.

This study found that women with polycystic ovary syndrome have higher global adiposity and increased visceral fat, particularly in the ip and mesenteric depots, compared to women without androgen excess.

This review discusses the pathophysiology, diagnosis, and treatment of congenital adrenal hyperplasia, but reports no new research results.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This study found that women with PCOS have elevated serum androgen levels throughout adulthood, with these levels decreasing and variations increasing as they approach menopause.

In this study, distinct metabolic profiles were identified in women with PCOS, suggesting potential biomarkers for diagnosis based on changes in lipid and androgen metabolism.

This study found that beta-caryophyllene enhanced re-epithelialization in cutaneous wounds of female mice, suggesting its potential for improving wound healing through multiple pathways.

This review discusses advancements in plant cell culture technology for producing potent natural cosmetic ingredients and reports no new experimental results.

This study found that Mentha pulegium essential oil had a stronger protoscolicidal effect against Echinococcus granulosus in vitro than Mentha piperita, showing dose- and time-dependent effects.

In castrated rats, this study found that triterpenoids from Ganoderma lucidum inhibited both types of 5α-reductase and reduced prostate growth linked to testosterone but not dihydrotestosterone.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This review highlights the chemical components and various potential health effects of Daucus carota but reports no new experimental results.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

This study found that finasteride decreased plasma dihydrotestosterone levels and altered steroid metabolism, similar to the profile of male pseudohermaphrodites with inherited 5a-reductase deficiency.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

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 observed that the ethyl acetate extract of Equisetum debile showed high activity against 5α-reductase and lipid peroxidation with no cytotoxicity on dermal papilla cells.

This study found that C. obtusa oils promoted hair growth in shaved mice and increased the expression of a hair growth regulator, VEGF, in a cell line.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This pilot study found that hair metabolome analysis may help differentiate pregnancy complications from healthy pregnancies by revealing significant metabolite differences between trimesters.

This review compiles current information about Eclipta prostrata, traditional uses, and its promising pharmacological properties, like hepatoprotective and anti-inflammatory effects, but emphasizes that more research is needed to fully understand its mechanisms and ensure safety for clinical application.

This study found that Insig deficiency in the skin of mice causes cholesterol precursors to accumulate, leading to defective hair development and skin abnormalities, which were alleviated by simvastatin treatment.

This review discusses the potential dermatological applications of Dendrobium officinale polysaccharides, noting their hair growth promoting, skin moisturizing, and antioxidant effects, but reports no new clinical results.

This animal study found that Cinnamomi cortex water extract reduced prostate weight and improved histological changes in a benign prostatic hyperplasia model, suggesting potential as a treatment.

This article provides an overview of diagnosing Cushing's syndrome, emphasizing the importance of assessing clinical signs and the appropriate use of first-line biochemical screening.

This study suggests that daughters of women with PCOS may have altered androgen metabolism in early childhood, with increased 5α-reductase activity potentially contributing to PCOS development.
