30 / 1000+ resultsresearch The Viscoelastic Properties of Chemically Modified alpha-Keratins in Human Hair
Chemical modifications can alter hair's stability and flexibility, with hydrophobic interactions helping maintain structure in humid conditions.
research 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 DSC-investigations of alpha-keratins and the specific effects of chemical treatments on human hair
Chemical treatments weaken hair's thermal stability and structure.
research Frequency of an electrophoretic variant of hair alpha keratin in human populations.
The hair keratin variant is mostly found in Caucasians.
research Cachexia and graft-vs.-host-disease-type skin changes in keratin promoter-driven TNF alpha transgenic mice.
TNF alpha in skin cells causes weight loss, hair and fat issues, and skin inflammation in mice.
research The Process of Cornification Evolved From the Initial Keratinization in the Epidermis and Epidermal Derivatives of Vertebrates: A New Synthesis and the Case of Sauropsids
Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.
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 Increased rate of hair keratin gene loss in the cetacean lineage
Cetaceans lost hair genes to adapt to water.
research Proteomic tools for the investigation of human hair structural proteins and evidence of weakness sites on hair keratin coil segments
Hair proteins have weak spots in their α-helical segments.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Experimental Modulation of the Differentiated Phenotype of Keratinocytes from Epidermis and Hair Follicle Outer Root Sheath and Matrix Cells
ORS and hair matrix cells balance growth and differentiation better than normal keratinocytes, with human dermal fibroblasts crucial for proper differentiation.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Keratinization of sheath and calamus cells in developing and regenerating feathers
Feathers become harder as they develop due to a change in keratin type.
research Ultrastructural localization of hair keratin homologs in the claw of the lizard Anolis carolinensis
Lizard claws have hair-like keratins similar to those in mammals.
research Recurrent functional divergence of early tetrapod keratins in amphibian toe pads and mammalian hair
Early tetrapod keratins evolved into toe pad proteins in amphibians and hair proteins in mammals.
research Insights on the Hair Keratin Structure Under Different Drying Conditions
Drying hair with a microfiber towel better maintains hair strength and structure than using a cotton towel or blow-drier.
research Keratin Biomaterials Activate Schwann Cells via Integrin‐Mediated Signaling and Promote Regeneration of Large Peripheral Nerve Defects in a Rabbit Model
Keratin biomaterials from human hair help nerve regeneration by activating Schwann cells.
research Study of the keratinization process in human hair follicle by X-ray microdiffraction.
Hair structure forms the same way inside and outside the body.

Hair follicle cells resist turning into skin cells.
research Embryonic keratinization in vertebrates in relation to land colonization
Keratinization in embryos helped vertebrates adapt to land by forming a protective skin barrier.
research Physiological and retinoid-induced proliferations of epidermis basal keratinocytes are differently controlled
Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.
