This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.

This study suggests that fibromodulin may regulate transforming growth factor-β activity during scar formation, influencing the transition from fetal scarless repair to adult scar-forming repair in rats.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

Created material boosts hair growth and kills bacteria for wound healing.

This review of 47 studies indicates that platelet preparations may significantly enhance cellular activity, wound healing, and facial aesthetic outcomes in facial plastic surgery, though potential publication bias should be considered.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

In this study, polymeric micelles containing retinoic acid were found to improve targeted delivery to hair follicle structures in human skin more efficiently than a marketed retinoic acid gel, suggesting potentially safer and more effective acne treatment.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

In this study, researchers found that intestine-derived human alpha defensin 5 enhances wound healing, reduces bacterial load, and promotes hair growth in murine burn wound beds by increasing LGR stem cell migration.

This review discusses the current challenges and strategies in hair follicle bioengineering for treating hair loss and reports no new clinical results; it highlights ongoing hurdles and future directions for developing functional hair regeneration therapies.

In this study using a rat model, discontinuing dutasteride improved some relaxant responses but did not fully restore erectile function, indicating a potential time-dependent detriment of the drug.

This study demonstrated that a new topical treatment using ketotifen-loaded microneedles, designed for prolonged release, significantly reduced inflammatory markers in an animal model of allergic conjunctivitis, suggesting enhanced therapeutic delivery and sustained ocular benefits.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study suggests that co-culturing human outer root sheath cells with human dermal papilla cells can restore their ability to induce hair growth by altering gene expression through paracrine signaling.

This study found that CoQ10 formulated in transethosomes showed improved penetration and a better clinical response in treating androgenic alopecia compared to CoQ10 solution.

This study reports the first case of eyelash elongation and thickening in a patient with hypereosinophilic syndrome taking the Janus kinase inhibitor ruxolitinib.

This article reviews hair and nail disorders in children, emphasizing their prevalence, congenital and acquired origins, and the diagnostic challenges compared to treatment, but reports no new clinical results.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that cefazolin-loaded silica nanoparticles embedded in polycaprolactone nanofibers successfully inhibited Staphylococcus aureus growth while maintaining stem cell viability, suggesting their potential use in wound healing.

This article discusses the association between chronic diffuse telogen hair loss in women and iron deficiency, supporting the view that iron's role is unclear and often overstated, but reports no new clinical results.

This article reviews the properties of cellulose nanocrystals for sustainable development but presents no new experimental results.

This study found that high-dose pterostilbene potentially reduced prostate hyperplasia and had strong antioxidant effects in male rats with benign prostatic hyperplasia, suggesting it might be more effective than vitamin C and resveratrol in similar contexts.

The book details skin conditions in older adults, their link to mental health, cancer treatment importance, hair loss remedies, and managing autoimmune and itchy skin.

This chapter reviews the prevalence, pathogenesis, and management of hair and scalp disorders but reports no new clinical findings.

This study observed that nail abnormalities often indicate underlying dermatological or systemic conditions, with psoriasis and infections being the most common causes among patients.

In this study, PEVIII, a nanocomposite chitosan-coated vesicle containing both α-hederin and hederacoside C, demonstrated notable antibacterial activity against Pseudomonas aeruginosa in a keratitis model, showing significant lesion reduction, tissue improvement, and decreased bacterial load and inflammatory markers compared to other treatments.
