510-540 / 1000+ resultsresearch Characterization of a First Domain of Human High Glycine-Tyrosine and High Sulfur Keratin-Associated Protein Genes on Chromosome 21q22.1
Researchers mapped and categorized specific keratin-associated protein genes on human chromosome 21q22.1.
research Mammalian Keratin-Associated Proteins (KRTAPs) Subgenomes: Disentangling Hair Diversity and Adaptation to Terrestrial and Aquatic Environments
Different hair types in mammals are linked to variations in specific protein genes, with changes influenced by their living environments.
research Loss of Epidermal Evi/Wls Results in a Phenotype Resembling Psoriasiform Dermatitis
Loss of a specific protein in skin cells causes symptoms similar to psoriasis.
research An Epistatic Effect of KRT25 on SP6 Is Involved in Curly Coat in Horses
The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.
research The Distribution of Melanocytes and the Degradation of Melanosomes in Fetal Hair Follicles
Fetal hair follicles have melanocytes with melanosomes at different stages, which are broken down into pigment particles in keratinocytes.
research Discovery of Autoantigens in the Hair Loss Disorder Alopecia Areata: Implications of Posttranslational Modifications
Scientists are still unsure what triggers the immune system to attack hair follicles in Alopecia areata.
research Absence of H2O2 Breakdown in Human Hair Medulla: Implications in Follicular Melanogenesis
Human hair medulla doesn't break down hydrogen peroxide, which may affect hair color formation.
research New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research Nanoindentation of Hair Cortex and Medulla Regions
research A Study of the Differentiation Products of the Hair Follicle Cells with the Electron Microscope
Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.
research Hard X-Ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research Ultrastructural Characteristics of Neonate Scalp Hair
Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.
research Genetic Interplays Between Msx2 And Foxn1 Are Required For Notch1 Expression And Hair Shaft Differentiation
Msx2 and Foxn1 are both crucial for hair growth and health.
research Evidence That the Satin Hair Mutant Gene Foxq1 Is Among Multiple and Functionally Diverse Regulatory Targets for Hoxc13 During Hair Follicle Differentiation
The gene Foxq1, controlled by Hoxc13, is crucial for hair follicle differentiation.
research Measuring Changes in Chemistry, Composition, and Molecular Structure Within Hair Fibers by Infrared and Raman Spectroscopic Imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research Evidence for Various Calcium Sites in Human Hair Shaft Revealed by Sub-Micrometer X-Ray Fluorescence
The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.
research Characterization of the Proteins of Guinea-Pig Hair and Hair-Follicle Tissue
Guinea-pig hair and follicle proteins are mostly similar, but follicles have more group 2 proteins and fewer group 3 and 4 proteins.
research Influence of Oxidative and Reductive Treatment on Human Hair: Analysis of Hair Damage
Chemical treatments and daily stresses damage hair, especially the cuticle layer.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Bubble Hair
Bubble hair deformity may be caused by hair shaft trauma and can improve with gentle hair care.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Cross-Linked Features of Mouse Pelage Hair Resistant to Detergent Extraction
Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.
research Lipid Losses and Barrier Function Modifications of the Brown-to-White Hair Transition
White hair has less lipid content and absorbs water differently than brown hair.
research Secondary Structure Estimation and Properties Analysis of Stretched Asian and Caucasian Hair
Stretching damages Caucasian hair's structure more easily than Asian hair.
research Fundamental Studies on the Interaction Between Moisture and Textiles. Part X. Moisture Sorption Properties of Wool and Hair Fibers
Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.
research A Systematic Review on the Lipid Composition of Human Hair
Lipids are crucial for healthy hair, protecting it from damage and breakage.
research Optical Coherence Tomography to Evaluate the Effects of Oxidative Hair Dye on the Fiber
Oxidative hair dye changes hair color and structure but doesn't weaken it.
research A Sensitive Assay for the Enzyme Activity in Hair Follicles and Epidermis That Catalyzes the Peptidyl-Arginine-Citrulline Post-Translational Modification
