This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

Detailed history and physical examination are crucial for diagnosing hair loss.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This article reviews recent advancements in understanding and treating androgenetic alopecia, focusing on new genetic insights, stem cell roles, and diagnostic tools, without reporting new clinical results.

In this study, adding δ34S isotope analysis to models modestly improved precision in estimating grizzly bears' salmon and terrestrial diets, but contributed little new information.

This study found that sex differences in somatostatin biosynthesis in rat hypothalamic neurons develop between postnatal day 1 and 5, influenced by the conversion of testosterone to estrogen.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This study identified shared gene expression changes and immune cell infiltration patterns that may contribute to hair loss in alopecia areata and cutaneous lupus erythematosus, but also highlighted factors that might preserve hair in psoriasis patients.

This book reviews the symptoms, diagnosis, and treatments for Polycystic Ovary Syndrome, providing a comprehensive exploration but reports no new clinical results.

Facelift surgery has evolved to focus on natural results and safety, with patient selection and postoperative care being key to success.

This study found that the Msx2 gene may regulate goose feather follicle development by influencing cell viability and gene expression, with potential implications for improving down production.

In this study, a novel biofilm-dispersing wound gel did not interfere with healing and may enhance it by reducing inflammation in murine models with full-thickness skin wounds.

This case report describes a basal cell carcinoma arising in association with a vellus hair cyst, which the authors note has not been previously reported.

This study observed that areola formation in mice requires exposure to pregnancy hormones and mechanical strain, beyond individual stimuli like hormonal milieu or strain alone.

This case report identifies collagenous gastritis as the cause of chronic gastrointestinal symptoms in a 27-year-old male, characterized by severe chronic inactive gastritis and a distinctive subepithelial collagen band.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

This study found that human meibomian glands differ significantly from free and hair-associated sebaceous glands in morphology and lipid composition, making them highly specialized holocrine glands.

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

In this study, researchers found that Notch signaling is crucial for late-stage epidermal differentiation and postnatal hair cycle homeostasis by regulating hair follicle stem cell proliferation and differentiation.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This study found that fluorescence excitation spectroscopy could be a promising noninvasive tool for assessing the effects of comedolytic agents like retinoids on acne-like lesions in rhino mice.

This study found that GS-KG9 and GS-E3D, bioactive ginseng extracts, reduced BBB disruption and neuronal apoptosis in the hippocampus of diabetic rats, suggesting potential therapeutic effects for diabetic patients.

This study found that knocking out the integrin β1 subunit in induced pluripotent stem cells enhanced their migration and improved their wound-healing effects in a mouse model.

This study adapted a method for culturing melanocytes from human hair follicles to horses, successfully creating partially melanotic equine melanocytes, potentially advancing hair follicle biology research across species.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

This study suggests that topically applied fusidic acid may penetrate only the most superficial layers of canine skin but can reach sufficient concentrations to potentially treat infections caused by pathogenic staphylococci.

In this study, overexpression of secretory phospholipase A2 Group-IIA in transgenic mice led to depletion of hair follicle stem cells and increased differentiation, linked to changes in histone modifications.

This article outlines methods to study the skin and its molecular traits, focusing on interpretation and techniques applicable to mouse models, including diverse assays and approaches like electron microscopy and large-scale lipid analyses.

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.
