This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

In this study, smoking status and intensity were significantly associated with moderate or severe androgenetic alopecia among Asian men, after accounting for age and family history.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

This study found that fullerene nanomaterials can significantly enhance hair growth and increase hair follicle numbers in both shaved and bald mouse models, as well as in cultured human skin sections.

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.

Martin-Perez et al. show that rapamycin's beneficial effects in a mouse model of Leigh syndrome are linked to the downregulation of protein kinase C.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

This study developed a portable electrospinning device that mimics hair for cosmetic thickening in a mouse model, showing performance comparable to benchtop models with added safety and cost benefits.

This study found that dual-frequency ultrasound with microbubble cavitation significantly enhanced minoxidil delivery and hair growth in both lab and animal models compared to single-frequency ultrasound, without damaging the skin in mice.

This study found that the prevalence of PCOS in Thai adolescents was 5.29%, with moderate acne identified as the strongest associated risk factor.

This study found that α-13′-carboxychromanol significantly accelerated wound healing and improved tissue quality in a mouse model, especially when delivered with bacterial nanocellulose under diabetic conditions.

This case collection reports that 15% azelaic acid gel can be effectively used as a monotherapy to treat mild-to-moderate adult female acne.

This study found that red ginseng oil promoted hair growth and protected against UVC-induced skin damage in mouse models.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This review discusses the role of skin enzymes in drug metabolism and emphasizes the need for models assessing enzyme activity to evaluate the safety and bioequivalence of topical generic drugs, highlighting efforts to standardize testing protocols for transdermal products.

This study found that combining LED yellow light with an engineered strain expressing CXCL12 improved wound healing and reduced inflammation in a mouse model of scald wounds.

This study demonstrated that RNA interference targeting mutant keratin genes can effectively correct hair shaft structural defects in a mouse model by reducing mutant gene expression.

This study investigated spanlastic nanovascular drug delivery systems and found that they can effectively enhance the transport and continuous release of medicines with small particle size, low polydispersity index, and satisfactory entrapment efficiency, showing potential as carriers for drug delivery.

This review discusses current and emerging treatments for alopecia areata, emphasizing systemic treatments for moderate to severe cases, and reports no new clinical results.

In this study, researchers found that the original four-factor model of causal illness attributions in the IPQ-R did not fit a Chinese sample, and instead identified a two-factor model focusing on psychological attributions and risk factors.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.

In this quasi-experimental study, 24-week tofacitinib treatment significantly improved hair regrowth in South Asian patients with alopecia areata, but a high relapse rate post-withdrawal signals the need for continuous treatment strategies.

This research introduces WomenCare, a web-based system using a machine learning model to predict PCOD risk by evaluating factors like age, BMI, and lifestyle habits; it aims to help women monitor their health but is not a substitute for a professional diagnosis.

This preclinical study found that Mesenchymal Stem Cell-derived Conditioned Media formulations were safe and effective in rat and mouse models for treating chemotherapy- and radiation-induced oral mucositis, demonstrating improved tissue regeneration and healing, most notably at higher concentrations.

This study found that Aloe vera and Citrus lemon extracts demonstrated notable antibacterial effects against Propionibacterium acnes in both lab and human skin models, with combined use resulting in a 67% reduction in acne, suggesting potential for future therapeutic applications.

In this study, the integration of obesity-related features and machine learning techniques significantly enhanced cardiovascular disease detection, with the XGBoost classifier achieving a 74% accuracy rate and improved metrics compared to other models.
