This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study found significant changes in gene expression related to skin structure and signaling pathways in AEC syndrome skin, offering new insights into the syndrome's molecular underpinnings.

This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This review explores the immunological aspects of epidermal differentiation in loricrin knockout mice, offering insights into keratinization and potential intrinsic factors affecting immune function, but provides no new clinical findings.

This review details the development of the alpha-helix model for protein structure proposed by Pauling and Corey and confirms its validity through X-ray studies of myoglobin and lysozyme.

In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.

This study found that while ethnic hair types share a common fibrous keratin structure, variations in keratin-associated proteins and lipids may lead to different macroscopic hair characteristics.

In this study, structural and functional brain abnormalities specific to visuospatial and somatosensory processing networks were observed in patients with anorexia nervosa, highlighting a critical role for the precuneus.

This study found that topical application of recombinant human MG53 protein mitigated nitrogen mustard-induced skin injuries in mice by preserving epidermal integrity and hair follicle structure.

This study found that FPR2 knockout mice experienced excessive hair loss and abnormal hair follicle structures, suggesting FPR2's protective role in hair regeneration through stem cell activity regulation.

This study found that ageing in women leads to significant structural and biological changes in the scalp hair follicle environment, which may affect hair growth.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

Some cells may slow melanoma growth, a protein could affect skin pigmentation, a gene-silencing method might treat hair defects, skin bacteria changes likely result from eczema, and a defensin protein could help treat multiple sclerosis.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This review discusses the current understanding of genes coding for hair and avian keratins, highlighting gene structure and protein sequences, but reports no new experimental findings.

Different keratin proteins are expressed in various epithelial cells at different stages, affecting cell structure and function.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This study found that full thickness wounds in Lanyu pigs led to altered molecular expression and abnormal skin structure, without regenerating key epithelial cells thought to aid in skin regeneration.

This study characterized keratin-based biomaterials that self-assemble into hydrogels, demonstrating their potential to achieve hemostasis in a lethal liver injury model through specific biomaterial-receptor interactions.

This study observed that genetic variation in the ovine KRTAP22-1 gene is linked to increased wool yield and decreased fiber curvature in sheep, indicating its potential use in breeding programs.

This study confirmed the localization of CK19 and vimentin in skin cells, with CK19 linked to hair growth and vimentin stabilizing fibroblast structure.

This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.

This review summarizes recent discoveries of GPCRs for lysophosphatidylserine and lysophosphatidylinositol, detailing their roles as lipid mediators, but reports no new experimental results.

This article reviews the impact of nutritional deficiencies on hair health, detailing how they can cause structural abnormalities, pigmentation changes, or hair loss; it presents no new clinical findings.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This study found that mesenchymal progenitor cells from human hair roots seeded onto polymer scaffolds stimulated the production of mineralized proteins, enhancing bone-like structures, with optimal results at a pore size of 35 µm.

Keratin structure changes during keratinization, but the exact model remains uncertain.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.
