This article reviews guidelines for testosterone replacement therapy in late-onset hypogonadism, emphasizing the need for clear indications and appropriate testing before treatment, but provides no new research findings.

This review discusses the role of inheritance, androgens, and microinflammation in androgenetic alopecia and suggests some plant-based folk remedies may help address these factors but reports no new clinical results.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This article reviews the role of exosomes in promoting axonal regeneration and discusses recent findings on how exosome-borne molecules might influence the PTEN-mTOR pathway in injured neurons; it reports no new experimental results.

In this study, various types of minor hair follicle damage were observed during follicular unit extraction, with paring and hair bulb injury being more apparent under microscopic examination.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

This chapter reviews treatments for alopecia areata and androgenetic alopecia but presents no new clinical findings, emphasizing the need for more effective and safe hair growth promoters.

The document concludes that individualized treatment for malignant epithelial tumors is necessary and more research on metastatic squamous cell carcinoma treatments is needed.

This discussion reviews common errors in judgment and technique in hair transplantation, outlining potential revisionary surgery options, but it reports no new clinical results.

This study found that the circular RNA circCOL1A1 influences the formation of superior-quality brush hair in white goats by regulating hair follicle stem cell behavior and interacting with the miR-149-5p/CMTM3/AR axis.

This review concludes that global literature supports the lipidosterolic extract of Serenoa repens as efficacious and safe for treating lower urinary tract symptoms, with some studies showing equivalence to common pharmacologic agents.

In this study, researchers developed a new murine model for transplanting vibrissae that mimics human hair transplantation, achieving successful hair growth in immune-deficient nude mice.

This research suggests that intraoperative unilateral occipital artery ligation can reduce the risk of complications like scalp necrosis, offering advantages such as improved visualization and reduced asymmetry during extensive scalp lift surgeries.

Using cheek skin and cartilage grafts for nose reconstruction after skin cancer surgery can maintain shape and function but may require multiple surgeries and hair removal in men.

This study describes a follicular automaton model that simulates human hair cycles and may replicate hair pattern evolution seen in diffuse or androgenetic alopecia.

This review discusses various nanocarriers for gene and genome editing therapies, highlighting that ionizable lipid nanoparticles show advanced delivery performance, while emerging polymer-based and exosome-inspired carriers are rapidly advancing for targeted applications.

This study found that deleting the Mof gene in mouse skin leads to severe defects in skin cell self-renewal, differentiation, and hair follicle growth, indicating that MOF is crucial for mitochondrial and ciliary gene expression and essential for skin development.

This study found that young women with PCOS exhibited altered white matter microstructure and reduced cognitive performance compared to matched controls.

The document reviews various hair and nail disorders, their causes, and treatments, emphasizing the need for proper diagnosis and the link between nail changes and systemic diseases.

This study discusses advancements in nanotechnology and theranostic dressings, which may significantly improve chronic wound care by effectively targeting biofilms and enabling real-time monitoring, although obstacles to broad applicability and sustainability remain.

This pilot study found no significant relationship between blood and hair mineral concentrations in generally healthy adults, though hair analysis may have potential for assessing long-term mineral trends.

This study highlights that polycystic ovary syndrome develops through genetic and environmental factors, with insulin resistance as a key mechanism, impacting the risk of metabolic and cardiovascular conditions.

In this study, oral spermidine supplementation was found to significantly prolong the hair follicle anagen phase and reduce hair loss, with effects persisting three months after treatment in healthy participants, suggesting potential therapeutic benefits for hair loss conditions.

This study found that long-term exposure to sodium valproate can increase oxidative stress and inflammation in rat stomach tissues, while treatment with rutin, a natural antioxidant, was associated with reduced markers of these effects at dosages of 50 mg/kg and 100 mg/kg.

3D-oxy exosomes may significantly boost hair growth, offering new treatment options for hair loss.
