research Molecular identification of keratinophilic fungi associated with hair scalp and antifungal activity of green‐synthesis zinc oxide nanoparticles
Green-synthesized zinc oxide nanoparticles effectively inhibit common fungi found on human scalp hair.
research Novel PLCL nanofibrous/keratin hydrogel bilayer wound dressing for skin wound repair
The new wound dressing promotes cell growth and healing, absorbs wound fluids well, and is biocompatible.
research A Novel Human Type II Cytokeratin, K6hf, Specifically Expressed in the Companion Layer of the Hair Follicle
K6hf is a unique protein found only in a specific layer of hair follicles.
research Leucine-activated nanohybrid biofilm for skin regeneration via improving cell affinity and neovascularization capacity
The biofilm enhances skin healing by promoting cell growth and blood vessel formation.
research Polyphenol-mediated biomimetic mineralization of sacrificial metal-organic framework nanoparticles for wound healing
New wound healing method using nanoparticles in a gel speeds up healing and reduces infection and inflammation.
research Keratin 75 Is a Component of the LINC Complex and Has an Essential Role in Mediating the SOX2 Rapid Healing Response during Wound Repair
Keratin 75 is important for fast wound healing and works with SOX2 and the LINC complex to help skin cells move and repair damage.
research Observation of cultured amelanotic melanocytes from hair follicles by atomic force microscopy
Amelanotic melanocytes from hair follicles are immature and likely don't transfer melanosomes to keratinocytes.
research Towards a Better Physical Understanding of Human Hair : Development of Fiber Tribology-Methods at the Micro- and Nanoscale
The study aimed to enhance physical measurement methods for examining micro-fiber surfaces, focusing on changes in hair surfaces due to different shampoo formulations. It investigated the physical changes at macro, micro, and nanoscale levels, emphasizing the friction and interaction properties of hair treated with hair care products. The research specifically examined three commercially available cationic polymers (Polyquaternium-10, Polyquaternium-87, and Jaguar C-13S) and their interaction with the negatively charged hair surface. A modified Universal Surface Tester provided results on hair friction properties, showing that all three polymers reduced friction forces, with Polyquaternium-87 achieving the highest reduction. The study also developed methods to separate various interaction forces, using a modified atomic force microscope to detect interactions between individual hairs.
research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research Common genetic hair shaft abnormalities may be visualized by light and electron microscope
Genetic hair shaft abnormalities can be seen with microscopes and often affect scalp hair.
research Pathogenesis of pili annulati
Pili annulati is caused by a protein metabolism disorder affecting hair structure.
research A Productive Black Facial Pore
A man had a black pore on his cheek, which was removed and found to be a hair follicle tumor.
research 839 Spatiotemporal antagonism in mesenchymal-epithelial Signaling in sweat versus hair fate decision
Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
research A Novel Mouse Type I Intermediate Filament Gene, Keratin 17n (K17n), Exhibits Preferred Expression in Nail Tissue
A new mouse gene, Keratin 17n, is mainly found in nail tissue and may explain why mice without Keratin 17 don't have nail issues.
research Enrichment for Living Murine Keratinocytes from the Hair Follicle Bulge with the Cell Surface Marker CD34
CD34 is a marker for isolating stem-like cells in mouse hair follicles.
research Hair Casts
Hair casts may be caused by repetitive hair pulling or styling and are often misdiagnosed.
research Tooth, hair and claw: Comparing epithelial stem cell niches of ectodermal appendages
The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.
research Painful thickened skin on the soles of the feet
The man has a genetic skin condition called pachyonychia congenita.
research Effects of Hair Fibers on Braking Friction Materials
Adding 1% hair fibers to brake materials improves friction and wear, making them more effective.
research Morphologische und histochemische Untersuchungen von Haut. Schleimhäuten und Klauen bei Schweinen mit experimentellem Biotinmangel4
Biotin deficiency in pigs causes hair loss, skin issues, and weak claws.
research In vitro 3D organotypic hair follicle-model for high-throughput substance testing
The 5050 MHA42MCS45 hydrogel blend is suitable for repairing load-bearing soft tissues.
research Identification of reptilian genes encoding hair keratin-like proteins suggests a new scenario for the evolutionary origin of hair
Reptiles have genes similar to hair proteins, suggesting hair's genetic origins predate mammals.
research Recent advances in X-ray microanalysis in dermatology.
Trace elements like calcium, iron, and zinc are unevenly distributed in hair, while sulfur is even, and increased phosphorus and potassium levels are linked to skin reactions.
