Zinc deficiency in monkeys causes skin issues and reproductive problems, but supplementation reverses these effects.

This study found that a regimen combining cyproterone acetate and testosterone buciclate induced reversible azoospermia in bonnet monkeys, highlighting its potential as an effective male contraceptive.

This study found that chemotherapy-induced alopecia was more prevalent among women, particularly those with genitourinary and breast cancer, and over half of affected women used wigs or bonnets to cope.

This article discusses female androgenetic alopecia but reports no new clinical findings.

This study found that certain gene sets, including those involved in ligand-gated ion channel signaling and cell adhesion, are associated with Tourette syndrome, suggesting a potential neurobiological basis for the disorder.

This report describes complications such as infection and scarring in men who underwent hair implantation for pattern baldness, suggesting these issues may occur broadly with this procedure.

This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

This review outlines the role of testosterone in male sexual development and its therapeutic use for male hypogonadism, covering its biosynthesis, secretion, metabolism, and various biological actions, but does not report specific study results.

This study found IL-17/IL-36 signaling to be predominant in both endotypes of Netherton syndrome, with distinct molecular profiles between NS-ILC and NS-SE lesions, offering potential therapeutic targets.

This study reviewed Woodhouse-Sakati syndrome and found it consistently associated with hypogonadism, decreased IGF1, and frontotemporal alopecia, with additional symptoms like intellectual disabilities and diabetes in some patients.

This study identifies KLK14 as a significant factor contributing to hair defects and skin inflammation in a mouse model of Netherton syndrome.

This study found that minoxidil induced cardiovascular toxicity in marmosets at higher doses than those affecting dogs, potentially due to the drug's exaggerated pharmacological effects.

This study found that scalp cooling did not entirely prevent permanent chemotherapy-induced alopecia in breast cancer patients, with a significant risk observed among postmenopausal women undergoing anthracycline and taxane-based chemotherapy.

In this study, single-cell RNA sequencing of hair follicle populations from hidradenitis suppurativa patients identified three endotypes, suggesting distinct epithelial-immune interactions that may guide stratified therapeutic approaches.

Solid Lipid Particle technology makes retinol more stable, effective, and gentle on the skin.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This study found that Musashi-2 regulates mRNA targets to restrict epithelial cell migration, revealing a key function of Msi2 beyond its known role in promoting cell growth.

This study identified four novel mutations in the C2orf37 gene among Woodhouse–Sakati syndrome patients, doubling known mutations, and found no significant link between isolated symptoms like deafness and dystonia and these mutations.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

In this study, pioglitazone treatment in insulin-resistant PCOS patients decreased relative 5alpha-reductase activity without significantly affecting cortisol levels or urinary cortisol excretion.

This study analyzed patients with X-linked dominant chondrodysplasia punctata and identified novel mutations in the emopamil-binding protein gene, highlighting the need for genetic testing alongside biochemical analysis for accurate diagnosis.

This study identified multiple factors affecting the severity of alopecia areata, suggesting they could inform a tool for measuring disease impact and guide treatment selection.

This review outlines a diagnostic approach for identifying non-PCOS pathology in women with androgen excess, emphasizing the importance of clinical history and biochemical phenotyping but reports no new clinical results.

This article reviews the use of alitretinoin for corticosteroid-refractory chronic hand eczema and explores its potential therapeutic benefits in other skin conditions, but reports no clinical results.

In this study, a low concentration zinc sulphate solution was investigated for managing recurrent herpes simplex infections, but no new clinical results were reported.

This case report describes an 8 cm giant pilomatricoma on a 67-year-old man's scalp, revealing distinct transcriptional patterns related to hair follicle factors and keratin through spatial gene expression analysis.

FFA in men shows unique features and treatment results vary widely.

This study detailed distinct immunophenotypic stages of alopecia areata in C3H/HeJ mice, providing an immune blueprint that may help identify therapeutic targets for disease pathways in humans.

In this animal study, researchers reported that acetaminophen increased LH and FSH hormones in male rats, with high doses affecting sperm production negatively, while avocado leaf extract reduced sperm motility and viability, suggesting potential adverse effects on male reproductive health.
