research Keratin Formation in the Hair Follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Internal Structure Changes in Bleached Black Human Hair Resulting from Chemical Treatments: A Raman Spectroscopic Investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research ecancermedicalscience
The study explored the use of ATR-FT-IR spectroscopy on single hair fibers to detect breast cancer by examining lipid content changes. It involved 12 female subjects, both with and without breast cancer. Results indicated that breast cancer patients had increased peak height ratios of C–H bending absorption bands in their hair spectra, with ratios over 1.0 suggesting cancer presence. These changes were linked to increased lipid material at the cuticle–cortex interface, possibly due to cancer signaling molecules affecting lipid biosynthesis. The study suggested that hair could serve as a non-invasive biosensor for early breast cancer detection, with findings consistent with previous research showing hair structure normalization post-cancer removal. It emphasized the need for precise targeting of hair regions for accurate analysis and proposed a role for lipid rafts in the observed changes.
research Electron Microscope Studies of Hair and Wool
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Results of Clinical Examinations, Laboratory Tests, and Ultrasonography in Dogs with Pituitary-Dependent Hyperadrenocorticism Treated with Trilostane
