450-480 / 1000+ results research Morphological analyses in fragility of pili torti with Björnstad syndrome
Pili torti hair is fragile due to loose keratin filaments and weak disulfide bonds.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research The location of the thioglycolic acid molecules in intrafibrillar unordered areas of the human hair keratin structure
Thioglycolic acid mainly affects the unordered areas in hair structure.
research X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research A novel monilethrix mutation in coil 2A of KRT86 causing autosomal dominant monilethrix with incomplete penetrance
A new mutation in the KRT86 gene causes a hair disorder with variable expression.
research Nanoindentation of Hair Cortex and Medulla Regions
research The Ziering Whorl Classification of Scalp Hair
The conclusion is that creating natural-looking hair restoration requires replicating natural scalp whorl patterns and inserting grafts at specific angles.
research 繰返し水平荷重を受ける筋違付鉄骨ラーメンの弾塑性性状に関する研究 : (その5)-歪硬化モデルを用いた理論解析-I- : 構造
The document explains common hair disorders and the basics of hair anatomy and life cycle.
research GWASs Identify Genetic Loci Associated with Human Scalp Hair Whorl Direction
Certain genes influence the direction of hair whorls on the scalp.
research Acquired progressive kinking of the hair following COVID‐19 disease
COVID-19 can cause hair to become progressively kinked.
research Structural Stability of Wild Type and Mutated α-Keratin Fragments: Molecular Dynamics and Free Energy Calculations
The Glu413Lys mutation in keratin affects hair stability, while Glu413Asp does not.
research The Molecular Architecture for the Intermediate Filaments of Hardα-Keratin Based on the Superlattice Data Obtained from a Study of Mammals Using Synchrotron Fibre Diffraction
Hard α-keratin has a universal molecular structure with a specific superlattice arrangement.
research Corkscrew Hairs in Trichoscopy of Trichotillomania
Corkscrew hairs can help diagnose trichotillomania.
research Hair Shaft Abnormalities. Pili Bifurcati: A Scanning Electron Microscopy Analysis
The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.
research The Ziering Whorl Classification of Scalp Hair
Craig Ziering created a system to classify scalp hair patterns, important for improving hair restoration surgery results.
research Vertebral epidermal transamidases
Transamidases are present in the epidermis but their exact role is unclear.
research Dataset from the uniaxial tensile testing of human curly hair fibers under different conditions
Curly hair's strength and flexibility vary with moisture and temperature.
research [Congenital hereditary hypotrychosis. Generalized autosomal dominant hypotrichosis with pili torti (hypotrichosis congenita hereditaria Marie Unna)].
A hereditary condition causes hair loss and twisted hair in some family members.
research Acquired curved hair is caused by fusion of multiple hair matrix cells
Curved hair can develop when hair cells merge abnormally during growth.
research Ultraviolet-Enhanced Trichoscopy—A New Tool to Assess Pili Annulati
UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.
research Trichorrhexis Invaginata and Netherton’s Syndrome
Recognizing bamboo hair helps diagnose Netherton’s syndrome.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells
Wool fibre curvature is due to longer orthocortical cells compared to paracortical cells.
research Pili Trianguli et Canaliculi Is a Defect of Inner Root Sheath Keratinization
The hair defect is due to abnormal inner root sheath keratinization.
research The occurrence of the ε-(γ-glutamyl)lysine cross-link in the medulla of hair and quill
research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy
TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.
research Mechanism research of yak hair stretching slenderization based on the changes of conformation and cell shape
Yak hair stretches mainly due to macromolecules slipping past each other.
research Cortical cell types and intermediate filament arrangements correlate with fiber curvature in Japanese human hair
Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.
