This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

This article discusses the structure and function of the skin and its role in skin disease pathophysiology and reports no new research findings.

This study concluded that the curliness of human hair, regardless of ethnicity, originates from the inhomogeneous internal nanostructure due to differences in the distribution of two types of cortices.

This study reported new crystallographic structures and polymorphs of finasteride, including several solvates with distinct X-ray diffraction patterns and thermally characterized properties.

This study found that disulfide bonds in keratin increase its strength and toughness, with some loss of α-helical structure under load, highlighting their role in trichocyte α-keratin's mechanical properties.

This study observed that increasing the γ-kerateine content in meta-kerateine materials led to reduced elasticity, solidity, and hydrolytic stability, and decreased hepatocyte attachment support.

This study examined the unique structural features of sinus hair follicles in the shrew Sorex unguiculatus, which suggest a specialization for vibration sensing.

This study found that specific mutations in the spike protein of SARS-CoV-2 may significantly alter its structure and affect how it binds to certain inhibitors, but experimental studies are needed to confirm potential clinical implications.

In this study, molecular dynamics simulations indicated that the Glu413Lys mutation in human hair keratin significantly affects the stability of coiled coil structures, whereas Glu413Asp showed no impact on stability.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

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.

In this study, researchers used cryo-electron microscopy to reveal how the natural compound osthole inhibits TRPV3 channels by binding to specific sites, changing the channel's conformation.

This study found that non-toxic polycarboxylic acids can achieve satisfactory hair perming effects with limited strength loss, suggesting they have potential as a safer alternative to harmful perming chemicals.

This study identified a new 65 kD and 48 kD keratin pair expressed in specific mouse epithelial sites, suggesting a unique evolutionary branch of hair-related keratins.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

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

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

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 examined the structural and biochemical mechanisms of human lipocalin prostaglandin D synthase, detailing substrate and product binding processes at the catalytic site and suggesting potential for drug delivery targeting hydrophobic molecules.

This study reports that Ca 2+ binding alters the dynamics and surface properties of PKD-like domains in Clostridium histolyticum collagenases, enhancing their stability and potentially aiding in collagen-targeting vehicle development.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

This study determined the molecular structure of finasteride and its related crystalline forms, highlighting different hydrogen-bond interactions and structural configurations in various crystalline complexes.

This study found that sulfur mustard affects hair follicles and sebaceous glands in the skin by causing cellular damage, inflammation, and disrupting wound healing processes in hairless mice.

This study characterized the Hoxc-13 gene from sheep wool follicles, noting its potential autoregulatory role and potential influence on skin function beyond hair keratin regulation.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study suggests that the outermost hair cuticle surface is rich in 18-methyleicosanic acid (18-MEA), supporting previous findings of its multilayer lipid and protein structure.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

In this study, the researchers report that a modified epimorphin-derived peptide shows potential for hair follicle regeneration, especially when used with 1% minoxidil in mice.
