This study found that in male mouse pancreatic islet β cells, testosterone enhances glucose-stimulated insulin secretion by being locally converted into dihydrotestosterone and estradiol.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

This study found that low temperatures and nitrogen deficiency trigger root hair elongation through a molecular mechanism involving the receptor kinase FERONIA and the TOR Complex 1.

This study reported a series of eight children with hereditary vitamin D-resistant rickets in Tunisia, identifying both common and novel mutations in the vitamin D receptor gene, and noting significant improvement with intravenous calcium treatment in most patients.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

In this study conducted at Bangabandhu Sheikh Mujib Medical University, researchers reported that males with androgenetic alopecia had significantly higher levels of serum LH, prolactin, testosterone, DHEA-S, and free androgen index, and lower levels of serum FSH and SHBG compared to those without hair loss.

This review discusses the role of DHEA in intracrinology, highlighting its impact on breast and prostate cancer treatment and potential as a menopause therapy, but reports no new research findings.

The researchers reported that hair bio element median derivatives bioassay is an effective and reliable method for evaluating the nutritional status of various bio elements, offering a non-invasive approach for nutritional health surveillance and precision medicine.

This review discusses the role of DHT in male sexual differentiation and fertility in individuals with 5α-reductase-2 deficiency, reporting no new clinical results.

In this study, researchers assessed the physical-chemical and microbiological stability of various pharmaceutical ingredients in the vehicle TrichoSolTM, finding differing beyond-use dates for the compounds, such as 180 days for cetirizine hydrochloride, but only 90 days for progesterone at higher concentrations.

This study found that visual hair density is better correlated with hair count and shaft diameter, leading to the development of the Hair Diameter Index used in planning hair restoration procedures.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

The researchers identified a pathogenic variant in the SRD5A2 gene among siblings with 46,XY disorder of sexual development, highlighting the importance of comprehensive genetic testing in diagnosis and management.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.

This study found that Bangladeshi patients with type 2 diabetes mellitus had significantly lower serum vitamin E levels compared to healthy individuals, with lower levels particularly observed in female and older patients, emphasizing the potential importance of antioxidant status in managing the disease.

This study found that extracts from heterotropic cultures of Scenedesmus deserticola JD052 enhanced hair-inductive properties in human dermal papilla cells more effectively than photoautotrophic extracts, likely through activation of AKT/β-catenin signaling, despite similar loliolide content.

This study identified the presence of the enzyme 1 alpha-hydroxylase in various extrarenal tissues, suggesting its potential role in modulating vitamin D function in peripheral tissues.

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 explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

New method, hair distribution width (HDW), improves accuracy in diagnosing androgenetic alopecia (AGA).

This study found a perfect correlation between laser Doppler velocimetry measurements of scalp blood perfusion after minoxidil application and sulfotransferase enzyme activity in hair follicles, indicating a potential non-invasive test to predict minoxidil response in female pattern hair loss.

This study found that pubic skin fibroblasts respond to androgens, increasing 5α-reductase activity via an androgen receptor-mediated mechanism, suggesting its potential as a marker of androgen action in vitro.

This study found that cyproterone acetate significantly reduced both serum 3α-AdiolG levels and hirsutism scores in women with idiopathic hirsutism, PCOS, or 21-hydroxylase deficiency, suggesting its effectiveness in treating excessive hair growth.

This study reported that testosterone levels over 150 ng/dL combined with lack of testosterone suppression during a low-dose dexamethasone suppression test may indicate androgen-producing tumors, though this wasn't consistent across all cases.

This study found that mental rotation and neuroticism demonstrated curvilinear relationships with hair loss, suggesting that dihydrotestosterone levels might affect spatial cognition and personality traits in men.

This study found elevated levels of IL-18 and free IL-18 in hidradenitis suppurativa patients compared to healthy controls, suggesting these cytokines may serve as novel biomarkers for disease activity, with correlations indicating their involvement in disease severity.
