Cold waving solutions quickly reduce cystine to cysteine in hair.

In this study, researchers found that the naked (N) gene in mice indirectly affects the synthesis of structural proteins in mouse hair, resulting in reduced high tyrosine protein content and unusual amino acid compositions.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This report identified longitudinal grooves in the hair shafts of four children, diagnosing them with uncombable-hair syndrome.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This article reviews small animal experiments reported from 1932 to 1952 in two dermatology journals and notes the contributions of Farris's book on laboratory animal care.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

In this study, researchers found histopathological similarities between L-tryptophan eosinophilic myalgia syndrome and idiopathic eosinophilic fasciitis, with certain unique inflammatory features present in the former.

This review explores the potential of selective 11β-HSD1 inhibitors to improve insulin sensitivity in type 2 diabetes, emphasizing the need for more clinical research and reports no new clinical results.

This study found that triglyceride and energy metabolic pathways are crucial factors influencing wool fiber diameter in fine-wool Alpine Merino sheep, providing insights for enhancing wool quality.

This review discusses the history and development of keratin biomaterials for biomedical uses, highlighting their biological activity and biocompatibility, and provides no new research findings.

This article reviews the challenges in studying keratin proteins and emphasizes the potential of modern proteomic techniques to advance their research, but it reports no new findings.

This study isolated and characterized two distinct types of caspase-like proteases from human epidermis, suggesting their involvement in keratinocyte differentiation and apoptosis processes.

This study found that DHHC13 is crucial for hair anchoring and skin barrier function, with its deficiency in Zdhhc13(skc4) mice leading to cyclic alopecia and skin abnormalities due to cornifelin deficiencies.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study provides a comprehensive overview of human umbilical cord mesenchymal stem cell-derived extracellular vesicles (HUCMSC-EVs), suggesting their potential to combat aging and alleviate age-related disorders by rejuvenating multiple organs in animal models and discussing engineering strategies to harness their full anti-aging potential.

This study found that dietary vitamin E influenced gene expression in rat livers, altering genes related to metabolism, coagulation, and steroid processing, and confirmed its effects on related biological endpoints.

This review article discusses recent progress in chitosan-based hemostatic hydrogels, highlighting their unique properties, such as biocompatibility and enhanced hemostatic performance, compared to traditional materials. The authors summarize their hemostatic mechanisms and future potential in improving emergency bleeding control.

This study found that ACOD1 deficiency in dermal papilla cells promotes mitochondrial dysfunction and contributes to cellular senescence in androgenetic alopecia, suggesting ACOD1 as a potential therapeutic target and 4-octyl itaconate as a promising treatment option for AGA.

This study found that caffeic acid treatment mitigated the negative effects of acrylamide toxicity in Wistar rats by normalizing tissue and serological indices.

In this study, acetone was not superior to other degreasers for enhancing the efficacy of trichloroacetic acid peels, and its higher flammability suggests using alternative degreasers to reduce workplace hazards.

This study found that 1′S-1′-acetoxychavicol acetate from Alpinia galanga inhibits Nox isozymes and suppresses testosterone-induced hair loss in a mouse model of androgenetic alopecia.

This study found that minoxidil combined with all-trans retinoic acid additively promoted hair growth in vitro by enhancing cell survival and reducing apoptosis compared to minoxidil alone.

This study found that the cocrystal of mycophenolic acid with isonicotinamide significantly improved solubility and dissolution rate, while two other cocrystals showed decreased performance in these areas.

This study reported that abietic acid, derived from pine rosin, showed antimicrobial effects and reduced biofilm biomass in laboratory tests against microorganisms like Staphylococcus aureus and Candida albicans, suggesting potential further applications for skin infections.

This study found that Ishophloroglucin A from brown seaweed may treat androgenic alopecia by inhibiting 5α-reductase and promoting hair growth-related factors in human dermal papilla cells.
