Oxidative stress can alter the expression level of microRNAs (miRNAs) and has a role in oxidative damage generated by reactive oxygen species (ROS). While previous studies have demonstrated that miR‑146a, miR‑21 miR‑150 are essential for ROS production heart disease, these miRNAs spinal cord injuries not yet been examined. The present study focused on examining during H2O2 stimulation rat neuronal (RN‑sc) cells. RN‑sc cells were treated with H2O2, harvested reverse transcription quantitative...
TiO2 nanoparticles were surface-modified by a convenient and mild sol–gel method. A novel hybrid membrane material was prepared crosslinking reaction based on poly(dimethylsiloxane) (PDMS) as organic matrix inorganic filler well agent. The chemical structure, mechanical thermal properties, swelling performance morphology of the membranes characterized investigated FTIR, SEM, TG, so on. results showed that surface modification method could make compatibility between component good. ultrathin...
Abstract Surface modification of biomaterials has been adopted over the years to improve their biocompatibility. In this study, aiming promote hydrophilicity and introduce natural recognition sites onto poly( L ‐lactic acid) (PLLA) films, chitosan its derivatives, carboxymethyl (CMC) N ‐methylene phosphonic (NPC), were used modify surface PLLA films by an entrapment method. The properties original modified measured using water contact angle measurement X‐ray photoelectron spectroscopy (XPS)....
Abstract Gastric cancer treatment remains a major challenge because of its aggressiveness and spread. In this study, we developed hydrogel system for the gastric cancer, which can kill tumor cells through photothermal action drug treatment. Based on formation Schiff base linkage, OSA/AHA/BP/PTX was prepared by mixing oxidized sodium alginate (OSA), aminated hyaluronic acid (AHA), black phosphorus (BP), paclitaxel (PTX) under physiological conditions, exhibited excellent effect slow release...
Nylon 46 with high molecular weight was successfully synthesized in supercritical carbon dioxide (sc-CO2) by one-step three-stage polymerization using the salt prepared from 1,4-diaminobutane and 1,6-adipic acid as a monomer. The process divided into three reaction stages: precondensation, postcondensation, vacuum. To prepare nylon 46, precondensation of salts pH over 7.23 first carried out at 190 °C under 30 MPa for 2 h. Then CO2 reactor exhausted along removing byproduct water, refilled...
Metabolic dysfunction-associated steatotic liver disease (MASLD) poses a considerable health risk. Nevertheless, its risk factors are not thoroughly comprehended, and the association between reticulocyte count MASLD remains uncertain. This study aimed to explore relationship MASLD.
Filler materials of soft tissue should have good biodegradable absorption and biocompatibility. To investigate feasibility keratin hydrogels used as filler materials, a with high molecular weight self-assembly ability was extracted from human hair using modified reduction method characterized sodium dodecyl sulfate–polyacrylamide gel electrophoresis, Fourier transform infrared, X-ray diffraction. An injectable hydrogel also prepared its water absorption, cell toxicity, histological behavior...
