270-300 / 1000+ results research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.
research Poster 148 Severe Hair Loss during Inpatient Rehabilitation due to Telogen Effluvium: A Case Report
A woman had temporary hair loss due to stress from a spinal cord injury.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
research Pan-tissue scaling of stiffness versus fibrillar collagen reflects contractility-driven strain that inhibits fibril degradation
Tissue stiffness is influenced by contractility, which suppresses collagen breakdown.
research General theory of skin reinforcement
Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.
research 364 Mechanical forces of human dermal fibroblasts significantly decrease with age
Skin cell strength decreases significantly as we age.
research Abstracts
The model helps improve medical devices by showing how skin deforms under pressure.
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 Reliability of Histopathology for the Early Recognition of Fibrosis in Traction Alopecia: Correlation with Clinical Severity
Histopathology is not reliable for detecting early fibrosis in traction alopecia or for showing how severe it is.
research Comments on ‘Strength and Deformation Behavior of Fine-Grained Soils Reinforced with Hair Fibers and Its Application in Pavement Design’ by Ayothiraman et al. [Journal of Natural Fibers, DOI: 10.1080/15440478.2021.1954129]
research Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
research Pili Annulati with Multiple Fragile Hairs
Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.
research The Role of Interface Geometry and Appendages on the Mesoscale Mechanics of the Skin
Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.
research A failure to relax.
The man had myotonia, which caused delayed hand grip relaxation.
research Traction Alopecia
Stopping tight hairstyles can prevent and reduce traction alopecia.
research Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Traction alopecia: the root of the problem
Tight hairstyles and chemical relaxers can cause hair loss known as traction alopecia.
research Traumatic Alopecia (without Traction Alopecia)
Traumatic alopecia causes hair loss from pulling or rubbing, leading to broken hairs and changes in the scalp.
research Fracture in Hierarchical Biomaterials: Human Hair
Human hair's structure makes it tough and resistant to breaking.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research WISP-1 induced by mechanical stress contributes to the fibrosis and hypertrophy of ligamentum flavum via the Hedgehog-Gli1 signaling
Mechanical stress causes ligament thickening through WISP-1 and Hedgehog signaling.
research Strain and Strain Recovery of Human Hair from the Nano- to the Macroscale
Human hair can almost fully recover its structure within about 1,000 minutes after being stretched.
research Skin aging as a mechanical phenomenon: The main weak links
Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.
research Comparison of the pharmacoeconomic profiles of treatment regimens for field pattern actinic keratoses
Some blood pressure medications are linked to a higher risk of skin cancer.
research Evaluation of risk of SSRI-associated impotence and low libido in men exposed to finasteride
Finasteride and SSRIs together increase impotence and low libido risk in men.
research Intermittent Chronic Telogen Effluvium
Emotional stress can trigger intermittent hair loss in chronic telogen effluvium, which may not improve with treatment if stress continues.
research 877 Integration of magnetic tweezers and traction force microscopy for exploring the mechanobiology of keratinocyte cell-cell and cell-matrix anchoring junctions
The conclusion is that a new method combining magnetic tweezers and traction force microscopy may help understand skin cell interactions and diseases.
research Tissue Laxity Based on Donor Tissue Ballooning
The document's conclusion cannot be provided because the document is not readable or understandable.
research Telogen Effluvium
Telogen effluvium is a type of hair loss that happens when stress or illness causes many hairs to enter the resting phase and fall out.
