Abstract In this study, we aimed to fabricate osteoconductive electrospun carbon nanofibers (CNFs) decorated with hydroxyapatite (HA) crystal be used as the bone tissue engineering scaffold in animal model. CNFs were derived from polyacrylonitrile (PAN) via heat treatment and carbonized mineralized by a biomimetic approach. The growth of HA crystals was confirmed using XRD, FTIR, EDAX analysis techniques. mineralization process turned hydrophobic (WCA: 133.5° ± 0.6°) hydrophilic CNFs/HA...
ABSTRACT An open reading frame in the genomic database of Mycobacterium tuberculosis H37Rv was identified as having homology with an outer membrane protein. We found that gene specified a protein belonging to OmpA family, which includes some porins gram-negative organisms. The amplified by PCR and cloned into Escherichia coli . Overexpression toxic host, but limited amounts could be purified from cells before growth ceased. A truncated devoid code for presumed signal sequence well expressed,...
Beneficial or adverse effects of Static Magnetic Fields (SMFs) are a large concern for the scientific community. In particular, effect SMF exposure during anticancer therapies still needs to be fully elucidated. Here, we evaluate at induction levels that cisPt-treated cancer patients experience imaging process conducted in Low field (200–500 mT), Open (300–700 mT) and/or inhomogeneous High (1.5–3 T) Resonance Imaging (MRI) machines. Human adrenergic neuroblastoma SH-SY5Y cells treated with...
Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of cell procedures is an important task professional associations devoted therapy. The Chinese Branch the International Association Neurorestoratology (IANR) completed first set guidelines governing application neurorestoration in 2011. IANR and (CANR) collaborated propose current version "Clinical Therapy Guidelines Neurorestoration (IANR/CANR 2017)". council...
In the present study, effects of different parameters needleless electrospinning systems on polyacrylonitrile (PAN) nanofibers morphology and diameter were studied. The electric field profile at surface spinneret zone was evaluated by Finite Element Method. PAN used as precursor to fabricate carbon nanofibers. Scanning electron microscope (SEM), X-ray diffraction Raman spectroscopy for electrospun analysis. results analysis indicated, in spinning direction, concentrated decayed rapidly...
The aim of this study was to predict the effects different parameters on conductivity mineralized PAN-based carbon nanofibers by artificial neural network (ANN) method.
Objective(s): Since the electric field is main driving force in electrospinning systems, modeling and analysis of distribution are critical to nanofibers production. The aim this study was investigating various parameters on polyacrylonitrile (PAN) morphology diameter. Methods: profile at nozzle zone evaluated by Finite Element Method. diameter were examined Scanning electron microscopy (SEM). Results: results indicated that concentrated tip nozzle. Moreover, spinning direction, surface...
Ca2+ within intracellular stores (luminal Ca2+) is believed to play a role in regulating release into the cytosol via inositol (1,4,5)-trisphosphate (Ins(1,4,5)P3)-gated channel (or Ins(1,4,5)P3 receptor). To investigate this, we incorporated purified Type 1 receptor from rat cerebellum planar lipid bilayers and monitored effects at altered luminal [Ca2+] using K+ as current carrier. At high presence of optimal [Ins(1,4,5)P3] cytosolic [Ca2+], short burst activity was followed by complete...
Time is infinite movement in constant motion. We are glad to see that Neurorestoratology, a new discipline, has grown into rich field involving many global researchers recent years. In this 2019 yearbook of we introduce the most advances and achievements field, including findings on pathogenesis neurological diseases, neurorestorative mechanisms, clinical therapeutic globally. Many patients have benefited from treatments cell therapies, neurostimulation/neuromodulation, brain–computer...
Certain features of electrospun PCL/PLLA nanofibrous scaffolds such as thickness, cross section density, strength, and elastisity can be tailored to mimic the native microenvironment required for bladder tissue engineering. In this study differentiation human smooth muscle cells (hBSMCs) cultured on was studied. The aligned fibrous with a thickness about 100 nm, used implement different mechanical stimulation. Longitudinal (0.7 MPa) traverse (0.02 Young's modulus constructed hybrid showed...
