This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

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.

This review discusses the pharmacology and toxicology of cyclooxygenase in skin, highlighting its role in inflammation, wound healing, and tumorigenesis, without presenting new clinical results.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review discusses the role of regulatory T cells in skin, including their impact on hair follicle regeneration, wound healing, and immune tolerance, without presenting new clinical findings.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.

In this study, DHT and calculated free DHT were linked to higher risks of incident cardiovascular disease and all-cause mortality in elderly men, while total testosterone and calculated free testosterone showed no such associations.

This review presents evidence that correlations exist between hair mineral imbalances and various diseases, though inconsistencies in results highlight the need for standardized preparation methods.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This review discusses the roles of immune responses and cells in skin health and disease, emphasizing recent insights into their mechanisms and potential therapeutic applications, but presents no new experimental results.

In this study, skin manifestations were observed in 48% of children with primary immunodeficiency disorders, often providing crucial diagnostic clues for early identification of these conditions.

This review develops expert-guided recommendations for hidradenitis suppurativa management, highlighting evidence for the effectiveness of antibacterial and anti-tumor necrosis factor therapies, but reports no new clinical trial results.

This review covers the ongoing debate on measuring underinsurance in health coverage and reports no new empirical results, recommending a national effort to standardize underinsurance metrics.

This study found that melatonin exposure promoted hair follicle fiber growth in Cashmere goat cultures, potentially influencing pathways related to the microvascular system and extracellular matrix.

This study provides the first crystal structure of the human SRD5A2 enzyme, revealing key insights into its function and inhibition which may aid future drug development.

This article reviews the impact of natural fungal pathogens on laboratory animal research and reports no new results, calling attention to infection risks with dermatophytes, Candida, and pneumonia in immunocompromised rodents.

This review discusses the broader roles of angiogenic factors, like VEGFs and FGFs, beyond angiogenesis, highlighting their involvement in various biological and pathological processes.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This article reviews the roles of lesser-known secreted phospholipase A2 isoforms in various biological processes, such as immune suppression, metabolic regulation, epidermal hyperplasia, and male reproduction, without reporting new clinical findings.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study found that elevated carbon dioxide levels may help mitigate water deficit stress in soybean roots by altering gene expression related to stress and nutrient transport.

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 study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This study found that finasteride effectively prevented testosterone-induced kidney stone formation in renal tubular cells by reducing COM crystal adhesion and crystallization.

Certain variations of the HDAC9 gene can increase or decrease stroke risk in the Chinese population.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.
