Research
720-750 / 1000+ resultsresearch 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 [Studies on monilethrix].
Monilethrix is not caused by a metabolic defect.
research Pili annulati with fragility: Electron microscopic findings of a case
The study found that hair fragility in Pili annulati may be caused by cavities and damage within the hair shafts.
research Types I and II Keratin Intermediate Filaments
Keratins are crucial for cell structure, growth, and disease risk.
research A gene for monilethrix is closely linked to the type II keratin gene cluster at 12q13
Monilethrix is linked to a gene cluster on chromosome 12.
research An epistatic effect of KRT25 on SP6 is involved in curly coat in horses
The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research Angora Mouse Mutation: Altered Hair Cycle, Follicular Dystrophy, Phenotypic Maintenance of Skin Grafts, and Changes in Keratin Expression
The angora mouse mutation causes long hair and hair defects due to a gene deletion.
research Testicular Seminoma in a Transgender Woman: A Case Report
Transgender women can still get testicular cancer, so proper screening is important.
research Faculty Opinions recommendation of Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice.
research Act Fast With Traction Alopecia to Avoid Permanent Hair Loss
Act quickly to prevent permanent hair loss from tight hairstyles.
research De novo mutations in monilethrix
Specific keratin gene mutations can cause monilethrix.
research STUDY ON CONNECTIVE TISSUE FIBRE IN NECK SKIN OF GOAT
Goat neck skin has a complex network of collagen, elastic, and reticular fibers.
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 Fibrosing alopecia in a pattern distribution in two brothers with pili multigemini
Genetic factors might cause fibrosing alopecia linked to hair shaft abnormalities.
research Human Hair Keratins.
research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research Trichorrhexis Nodosa
Trichorrhexis nodosa is mainly caused by hair trauma and improves with gentler hair care.
research Netherton Syndrome With Trichorrhexis Invaginata “Bamboo Hair” Under Dermoscopy: Case Images
Netherton syndrome causes skin and hair issues, confirmed by "bamboo hair" under dermoscopy, with no cure but managed with topical treatments.
research COEXISTENCE OF TRICHOSTASIS SPINULOSA AND ERUPTIVE VELLUS HAIR CYSTS
Recognizing both trichostasis spinulosa and eruptive vellus hair cysts together is crucial for accurate diagnosis and treatment.
research A general mathematical model for the in vitro assembly dynamics of intermediate filament proteins
The model shows that filament flexibility and amino acid differences affect how fast intermediate filament proteins assemble.
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 Dynamics of Actin Filaments Play an Important Role in Root Hair Growth under Low Potassium Stress in Arabidopsis thaliana
Actin filaments help root hairs grow faster and longer under low potassium stress.
research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.
research The Friar Tuck sign in trichotillomania
An 8-year-old boy with hair-pulling disorder had a bald patch that was confirmed not to be a fungal infection and was treated with therapy.
research 1440 DNA dioxygenases Tet2/3 regulate gene promoter accessibility and chromatin topology in lineage-specific loci to control keratinocyte differentiation and hair growth
Tet2 and Tet3 enzymes are important for controlling hair growth and shape by affecting gene activity and DNA structure in hair follicles.
