This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

Insulin resistance linked to obesity may increase COVID-19 severity.

This study found that both alopecia areata and androgenetic alopecia moderately reduced the quality of life for Chinese patients, especially in younger individuals and those experiencing hair loss for over a year.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.

In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.

This study found that circRNA-0100 promotes differentiation of secondary hair follicle stem cells into hair lineage in cashmere goats by sequestering miR-153-3p, which enhances KLF5 expression.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study introduced RoPod, a customizable tool for low-stress live imaging of Arabidopsis roots, which improves data reproducibility and provides new insights into plant autophagy by revealing detailed, cell type-specific responses to chemical modulators.

This chapter reviews the biosynthesis, mechanism of action, and therapeutic effects of testosterone and related androgens, but reports no new research findings.

This study found that cows with alopecia, ill-thrift, and infertility exhibited significant decreases in serum copper, zinc, calcium, inorganic phosphorus, magnesium, and hematological measures, indicating moderate microcytic, hypochromic anemia.

This study found that the M5 isolation method for human dermal papilla cells significantly improved attachment efficiency, proliferative capacity, and trichogenic potential, providing an optimized strategy for scalable manufacturing in hair regeneration therapies for conditions like alopecia.

This study found that dental students' manual dexterity was weakly associated with their performance in skills-based assessments, while self-perceived skill levels showed no significant correlation with assessment outcomes, suggesting a potential benefit from focusing on dexterity enhancement in dental education.

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

In this study, male patients with stage III-IV androgenetic alopecia who underwent hair transplantation using a technique that considers the direction and angle of hair growth reported a 19.7% increase in satisfaction regarding the naturalness of their results.

This study found a significant association between androgenetic alopecia and metabolic syndrome, with AGA patients showing higher BMI, waist circumference, blood glucose, and cholesterol levels compared to controls.

This review highlights that vitamin D is increasingly recognized for its roles in skin health, including treatment of psoriasis, potential applications in conditions like atopic dermatitis, and possible prevention of skin malignancies, as observed in various studies linking low levels to autoimmune skin diseases.

This article discusses the widespread issue of zinc deficiency affecting plant, animal, and human health, and reports no new clinical results; the authors emphasize the need for adequate zinc availability in agriculture and nutrition.

This source outlines common health issues in weanling gerbils, including skin infections often tied to beta-hemolytic Staphylococcus aureus, and obesity-related conditions like diabetes, as well as respiratory infections and musculoskeletal problems, without detailing specific new study results.

This paper discusses the relationship between androgenetic alopecia and cardiovascular atherosclerosis, focusing on carotid intima-media thickness and the SYNTAX score, and reports no new results.

Severe hair loss (androgenetic alopecia) is linked to higher risk of heart disease (cardiovascular atherosclerosis).

This consensus report reviews current knowledge and identifies knowledge gaps concerning the various health aspects of polycystic ovary syndrome, without presenting new clinical findings.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This review discusses the limitations of animal models, particularly mice, in accurately predicting human skin wound healing outcomes and emphasizes understanding species-specific differences in skin characteristics for better translation to clinical settings.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This review discusses how women with PCOS have an increased risk of insulin resistance and cardiometabolic features regardless of body fat, and calls for targeted prevention and management strategies.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.
