570-600 / 1000+ resultsresearch The use of electron spin resonance techniques to determine gamma ray exposure of $\alpha$-keratin in human hair
Whole hair strands can reliably measure gamma ray exposure using ESR techniques, but samples should be analyzed quickly or stored in liquid nitrogen.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Investigation of human hair using ToF-SIMS: From structural analysis to the identification of cosmetic residues
The conclusion is that a new method can identify cosmetic residues on hair and match them to their products.
research Cyclical Changes in Rat Vibrissa Follicles Maintained In Vitro
Rat vibrissa follicles are useful for studying hair growth cycles, especially the transition from pro-anagen to anagen.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.

research The optical properties of human hair II. The luster of hair fibers
research Double-wavelength laser scanning microphotometer (DWLSM) for in-vitro hair shaft and surrounding tissue imaging
The DWLSM provides detailed imaging of hair shafts and follicles with high accuracy.
research Carbon-13 n.m.r. studies of keratin intermediate filament of human hair
Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.
research Valency based novel quantitative structure property relationship (QSPR) approach for predicting physical properties of polycyclic chemical compounds
The neighborhood face index (NFI) accurately predicts properties of complex molecules.
research Analyzing the laser-light reflection from human hair fibers Part1: Light components underlying the goniophotometric curves and fiber cuticle angles
Hair color affects light reflection, with black hair having higher cuticle angles and lighter hair showing less specular reflection.
research Efeito da radiação ultravioleta na cor, na perda proteica e nas propriedades mecanicas do cabelo
UV radiation causes significant protein loss and color changes in hair, especially blond hair.
research Characterization of hair lipid and protein dynamics using EPR spectroscopy and treatment effects
Hair treatments and dehydration affect hair's lipid and protein behavior, influencing its flexibility and appearance.
research Evaluation of a new X-ray fluorescent analysis technique for the creation of a Nordic hair database: elemental distributions within the root and the virgin segment of hair fibers.
The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
research Biophysical basis of skin cancer margin assessment using Raman spectroscopy
Raman spectroscopy could effectively guide skin cancer surgery by identifying tumor margins.
research Scattering from Elliptical Hair Fibers Based on Microfacet Theory
research 130 Examples of Tumors Diagnosis Via Quantum Resonance Spectrometer
Cancer patients have lower immunity and higher virus and zinc levels in their hair.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research Innervation Patterns of Harp Seal (Pagophilus groenlandicus) Vibrissal Sensory Systems
Harp seals have different innervation patterns in their whiskers, with lateral whiskers having more axons than medial ones.
research Performance scanning electron microscopic investigations and elemental analysis of hair of the different animal species for forensic identification
Scanning electron microscopy and elemental analysis can help identify animal species by their hair patterns and elements.
