This study reports that a specific transporter protein in Staphylococcus hominis is responsible for transporting a malodour precursor, thereby playing a key role in human body odor production.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

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 S-Methylmethionine sulfonium (SMMS) enhances cell survival and reduces damage from UVB irradiation in skin cells, suggesting its potential as a cosmetic ingredient for UV protection.

This study found that a quinazoline derivative, SH-340, increased skin barrier-associated factors and inhibited TSLP expression and STAT6 phosphorylation in human primary keratinocytes, suggesting potential benefits for alleviating inflammation and improving skin barrier function in atopic dermatitis.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

This study found that at pH 9.0, CYS penetrated less and caused less damage to virgin human hair than TG because it barely reached the cortex region.

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

This study found that alkyl shikimates with different alkyl group structures can increase or decrease fibroblast proliferation depending on concentration and alkyl chain length, with some variants showing cytotoxic effects due to their hydrophobicity and cell membrane permeability.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.

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 found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

This study found that the tetrazolium salt INT is the most effective for revealing dehydrogenase activity and certain histological structures in sheep and other mammals' skin.

This study found that a conditioner treatment using 18-MEA combined with a specific cationic surfactant effectively restored hydrophobicity and reduced friction on damaged hair surfaces.

This review discusses the structural and functional advances in understanding sulfotransferases and sulfatases, highlighting new insights into enzyme mechanisms and inactivation by clinically relevant aryl sulfamates, but provides no new experimental results.

This review discusses the intracellular activity of β-thymosins and their role in modulating the actin cytoskeleton, but it reports no new experimental results.

This study found that treating reconstructed human epidermis with beta-lipohydroxy salicylic acid increased tight junction remnants in the stratum corneum, potentially affecting skin cohesion and desquamation.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study describes a microfluorometric method to quantify lipid removal and reattachment on human hair during light exposure and chemical treatments, altering hair surface properties from hydrophobic to hydrophilic.

Minoxidil can cause severe skin reactions like Stevens-Johnson syndrome in rare cases.

Calcipotriol may effectively treat hair loss in alopecia areata, working better in children than adults.

In this study, treating hair with thioglycolic acid was found to alter disulfide bond patterns in keratin-associated proteins, shifting them from an ellipsoidal to a near-spherical shape.

A new method strengthens hair without using harmful chemicals.

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study optimized a screening assay to identify molecules that inhibit or enhance TRPM5 ion channel activity, which may have implications for treating dysfunctions linked to cardiac arrhythmias and diabetes.
