This paper reviews plica polonica, a rare hair disorder linked historically to poor hygiene and now to severe self-neglect or medical conditions, and outlines various treatment and preventive strategies but reports no new findings.

This review discusses polycystic ovary syndrome, focusing on its primary features of ovulatory dysfunction and hyperandrogenism, and reports no new findings.

Data-driven methods can help understand microbiota's role in diseases and develop personalized treatments.

This study found a statistically significant increase in glycosylated hemoglobins among patients with adult-acquired panhypopituitarism undergoing long-term GH replacement therapy, with two developing diabetes requiring treatment.

This study observed that while dexamethasone-cyclophosphamide pulse therapy is relatively free from hypertension and diabetes compared to conventional steroids in pemphigus patients, it frequently causes generalized weakness and flushing.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study reports that X chromosomes often show greater differentiation between human populations than autosomes, likely due to a mix of demography and selection pressures.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This review summarizes the promising role of melatonin combined with nanosized carriers in drug delivery, suggesting enhanced effectiveness in treating various diseases compared to free melatonin.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study identified several genes regulated by dihydrotestosterone in an SV40T-transformed human dermal papilla cell line, which may play a role in androgen-mediated hair growth regulation.

This study developed a DPC cell line by introducing mutant CDK4, Cyclin D1, and TERT, making it a promising tool to study downstream signaling pathways activated by testosterone in androgenetic alopecia.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

The document concludes that individualized treatment and lifestyle changes are important for managing menopause symptoms and health risks.

This review synthesizes evidence on the prevalence, impacts, causes, and treatment of erectile dysfunction in men under 40 but reports no new clinical results; the authors emphasize the need for comprehensive evaluation and individualized care.

Pigs are a good model for studying human hair growth and disorders.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This study suggests that personality plays a significant role in how psychological factors influence the onset and progression of alopecia areata, as well as its psychosocial impacts.

This article reports that follicular unit extraction is a minimally invasive hair restoration technique that avoids linear scarring and reduces donor-site pain compared to traditional strip harvesting methods.

This review suggests that "polycystic ovarian syndrome" is a misleading name, as the disorder involves complex metabolic and reproductive issues beyond ovarian dysfunction and may stem from factors affecting the fetus in utero.

This source explores the association between alopecia areata and thyroid dysfunction, highlighting a particularly strong link with Hashimoto thyroiditis and hypothyroidism.

This review discusses the role of growth factors in hair physiology and their involvement in conditions like androgynous and focal alopecia, reporting no new clinical findings.

This thesis explores both environmental and genetic factors in prostate cancer, focusing on surrogate hormone markers, medical radiation, family history, and genetic polymorphisms related to DNA repair and hormone marker genes, but reports no new clinical findings.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This review evaluates dihydrotestosterone's role in androgenic alopecia and proposes a model suggesting that chronic scalp tension and inflammation contribute to hair follicle miniaturization, identifying fibrosis, calcification, and tension as treatment targets.

This article reviews the role of polyamines in hair follicle growth and discusses potential therapeutic applications but provides no new clinical results.
