No Genetic Vertigo Peoples living in high altitudes have adapted to their situation (see the Perspective by Storz ). To identify gene regions that might contributed high-altitude adaptation Tibetans, Simonson et al. (p. 72 , published online 13 May) conducted a genome scan of nucleotide polymorphism comparing Han Chinese, and Japanese, while Yi 75 ) performed comparable analyses on coding all genes—their exomes. Both studies converged gene, endothelial Per-Arnt-Sim domain protein 1 (also...
Autologous nerve transplantation, which is the gold standard for clinical treatment of peripheral injury, still has many limitations.In this study, aligned chitosan fiber hydrogel (ACG) grafted with a bioactive peptide mixture consisting RGI (Ac-RGIDKRHWNSQGG) and KLT (Ac-KLTWQELYQLKYKGIGG), designated as ACG-RGI/KLT, was used conduit filler to repair sciatic defects in rats.Methods: Chitosan nanofiber prepared by combination electrospinning mechanical stretching methods, then KLT, are...
Rehabilitation and regenerative medicine are two promising approaches for spinal cord injury (SCI) recovery, but their combination has been limited. Conductive biomaterials could bridge scaffolds with electrical stimulation by inducing axon regeneration supporting physiological signal transmission. Here, we developed aligned conductive hydrogel fibers incorporating carbon nanotubes (CNTs) into methacrylate acylated gelatin (GelMA) via rotating liquid bath electrospinning. The electrospun...
Background: Designing novel biomaterials that incorporate or mimic the functions of extracellular matrix to deliver precise regulatory signals for tissue regeneration is focus current intensive research efforts in engineering and regenerative medicine. Methods results: To natural environment spinal cord tissue, a three-dimensional hierarchically aligned fibrin hydrogel (AFG) with oriented topography soft stiffness has been fabricated by electrospinning concurrent molecular self-assembling...
Nerve guidance conduits (NGCs) have been widely accepted as a promising strategy for peripheral nerve regeneration. Fabricating ideal NGCs with good biocompatibility, biodegradability, permeability, appropriate mechanical properties (space maintenance, suturing performance, etc.), and oriented topographic cues is still current research focus. From the perspective of translation, technique stability scalability are also an important consideration industrial production. Recently, blow-spinning...
A simplified approach to increase neuronal attachment on an agarose hydrogel was proposed by blending with another biocompatible polysaccharide, chitosan. The stiffness of the gel maintained despite inclusion chitosan, as determined rheological tests. structure blended hydrogels characterized using light microscopy and scanning electron microscopy. An in vitro cell study revealed that blends promoted neuron adhesion. concentration chitosan had great influence morphology neurons. optimum...
Using bismuth oxide (Bi2O3) as a laser-marking additive and thermoplastic polyurethane (TPU) the matrix, TPU/Bi2O3 composite materials were prepared by melt blending in torque rheometer. The sheet samples from composites treated air scanning with neodymium-doped yttrium aluminum garnet (Nd: YAG) pulsed laser beam at wavelength of 1064 nm. Compared pure TPU sample, laser-marked exhibited differences marking contrast Bi2O3 content increased 0.1% to 1.0% based on stereomicroscope analysis....
Mesenchymal stem cell (MSC)-based regenerative medicine is widely considered as a promising approach for repairing tissue and re-establishing function in spinal cord injury (SCI). However, low survival rate, uncontrollable migration, differentiation of cells after implantation represent major challenges toward the clinical deployment this approach. In study, we fabricated three-dimensional MSC-laden microfibers via electrospinning rotating culture to mimic nerve tissue, control behavior,...
Hollow silica nanospheres with mesoporous shells were successfully fabricated a new one-pot strategy by using thermosensitive polymer, poly(N-isopropylacrylamide) (PNIPAm), as reversible template without the need of further calcination or chemical etching. By simply regulating solution temperature respect to lower critical (LCST) PNIPAm, PNIPAm chains can reversibly form aggregates dissolve in aqueous solution. The character makes behave soft templates for formation core-shell at elevated...
ABSTRACT The present work aimed to develop polyvinyl alcohol (PVA) hydrogel films with physically crosslinking through controllable entanglement density of the polymer chains. viscoelasticity PVA aqueous solutions was investigated over a broad range in molecular weight. chain length between crosslinks () and determined by plateau modulus ( G' ). value increased weight, which can be attributed enhanced associated hydrogen bonds inter‐ interchains. melting crystallization transparent showed...
In this work, poly(ethylene terephthalate) (PET) chain-extending products with different molecular weights were prepared by reactive extrusion using isocyanate trimer (C-HK) as the trifunctional chain extender.
