Research
690-720 / 1000+ results research Design and fabrication of customizable microneedles enabled by 3D printing for biomedical applications
3D-printed microneedles improve drug delivery and diagnostics but face scalability and regulatory challenges.
research Hair and Nail Relationship
Hair and nails are similar keratin structures with different shapes and growth, affected by the same diseases and environmental factors.
research Leveraging Crosslinker Diffusion to Template Stiffness Gradients in Alginate Hydrogels
Stiffness gradients in alginate gels can guide cancer cell invasion and study cellular behaviors.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
research Dynamic ultrastructural changes of the connective tissue sheath of human hair follicles during hair cycle
The connective tissue around hair follicles changes structure throughout the hair cycle.
research Acidic and basic hair/nail ("hard") keratins: their colocalization in upper cortical and cuticle cells of the human hair follicle and their relationship to "soft" keratins.
Hair and nail cells share similar proteins, indicating a common differentiation pathway.
research The mineralization of hair follicle tissue
Hair follicle tissue can induce mineral formation, likely due to a potent nucleator.
research In situ tensile deformation characterization of human hair with atomic force microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
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 Attenuated Total Reflection Fourier Transform Infrared Spectroscopy Analysis of Human Hair Fiber Structure
Human hair has different protein structures in its cuticle and cortex.
research Homogenization theory captures macroscopic flow discontinuities across Janus membranes
The homogenization theory effectively describes how flow behaves differently across asymmetric membranes.
research Structural abnormalities of the hair shaft
The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Association of iron levels in hair with brain structures and functions in young adults
Higher hair iron levels are linked to changes in brain structure and function.
research The structure and organization of lanceolate mechanosensory complexes at mouse hair follicles
Lanceolate complexes in mouse hair follicles are essential for touch and depend on specific cells for maintenance and regeneration.
research In vivo silica nanoparticle translocation across human stratum corneum: the effect of surface hydrophobization in relation to hair follicle density.
Hydrophobized silica nanoparticles penetrate the skin's outer layer more effectively, while hair follicle density doesn't impact their accumulation.
research Characterization of surface deposits on human hair fibers
research Fine Structure of the Fully Keratinized Hair Cuticle in the Head Hair of the Human
Human hair cuticle has five cell layers with specific junctions and granules.
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 LB1081 Three-dimensional imaging of tight junction-network across multiple layers of human epidermis by array tomography using backscattered electron-mode scanning electron microscopy
The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.
research Electron microscopy in dermatology--basic and clinical research : proceedings of the Joint Meeting for the Japanese Society for Ultrastructural Cutaneous Biology and the Society for Cutaneous Ultrastructure Research, Nara, Japan, 24-27 October 1993
Electron microscopy helps understand skin structure and diseases.
research Integral characterization of normal and alopecic hair at different degeneration stages by in-situ visible and chemical imaging
Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.
research Some observations on the proteins of the inner root sheath cells of hair follicles
research Study shows thicker hair isn’t necessarily stronger
Thicker hair isn't always stronger.
research Electron Microscope Studies of the Human Epidermis The Clear Cell of Masson (Dendritic Cell or Melanocyte)
A unique skin cell similar to hair bulb melanocytes was identified, with better preservation using permanganate fixation.
research Investigating the internal structure of sheep wool hair fibre using new microscopic techniques
Curly wool has more orthocortex than straight wool.
research Collective heterogeneity of mitochondrial potential in contact inhibition of proliferation
Mitochondrial activity varies in cells before they stop growing, affecting their growth potential.
research Multi-omics analysis of functional substances and expression verification in cashmere fineness
The study concluded that the arachidonic acid pathway and the protein KRT79 play a role in determining the fineness of cashmere.
research Spatial and single-cell transcriptomics unravel the complex interplay between the body and medical implants
New technologies help us understand how the body reacts to medical implants, which can improve implant performance.
