The document provides a practical guide for diagnosing and treating various types of hair loss.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This study introduced a multitask learning method to identify shortcut learning in clinical ML systems, revealing it's not always responsible for unfairness and emphasizing the necessity of comprehensive fairness approaches in medical AI.

In this descriptive study, elderly patients most commonly presented with skin wrinkling, xerosis, and eczematous conditions, highlighting the difficulty in distinguishing normal age-related from pathological skin changes.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

In this study, researchers developed a 3D in-vitro system for generating functional AT-resident macrophages without cell sorting, providing a valuable tool to study their differentiation and function in various physiological and pathological conditions.

This article reviews the evolving understanding of hematopoietic stem cells, including their heterogeneity and the role of cytokines in lineage determination, and reports no new results.

This chapter reviews the biology and regulatory mechanisms of epidermal stem cells, emphasizing their heterogeneity and roles in skin homeostasis, cancer, and aging, without reporting new findings.

This study in mice found that using modified illite as a carrier for topical minoxidil enabled effective delivery without the solvent toxicity typically associated with minoxidil, while the illite also promoted hair growth through anti-inflammatory and pro-proliferative mechanisms.

E13 fetal mouse fibroblast vesicles may help reduce scarring.

This review synthesizes the latest advances in wound healing and scar management, exploring molecular mechanisms, therapeutic strategies, and providing an evidence-based comparison of topical agents like Dermatix Ultra and Contractubex for scar improvement, aimed at informing clinicians and patients in decision-making.

This study reported that age and diabetes are major factors influencing trichilemmal cyst development and size, highlighting the importance of these conditions for risk assessment and surgical planning.

In this study, researchers identified two types of potassium channels, BK and Kv4.2, in rat Merkel cells and reported that these channels play important roles in repolarizing action potentials and maintaining resting membrane potentials, potentially influencing tactile encoding in these cells.

This study found that HairTime, a novel non-invasive assay using hair samples, accurately estimates chronotype and reveals its plasticity influenced by work schedules and lifestyle factors.

This study identified 11 previously unreported ABCA12 variants associated with varying severities of autosomal recessive congenital ichthyoses and expanded the phenotype spectrum of ichthyosis linked to these variants.

This study found that polymorphism in the STK11 gene does not predict metformin therapy response regarding menstrual regularity and other symptoms in women with polycystic ovary syndrome, despite observed improvements in several health markers post-treatment.

This study observed that incorporating human follicle dermal papilla cells into fibrin microgels increased cell viability and the formation of hair follicle structures in in vitro skin cultures compared to traditional dermal papilla spheroids, suggesting a promising approach for hair follicle regeneration therapies.

This study observed a high degree of plasticity in somatosensory axons innervating Merkel cells in mouse skin, finding that both axons and Merkel cells underwent dynamic remodeling, with their interactions influencing axonal branching and maturation.

This study found that inhibiting the gp130 Y814 signaling module promotes tissue regeneration and may prevent pathological outcomes after injury in animal models.
