Chitosan oligosaccharide attenuates acute kidney injury and renal interstitial fibrosis induced by ischemia-reperfusion.Acute kidney injury (AKI) and renal interstitial fibrosis are global clinical syndromes assorted with high morbidity and mortality. Renal ischemia-reperfusion (I/R) injury, which commonly passs during surgery, is one of the major movements of AKI an efficient therapeutic approach for AKI and the development of renal interstitial fibrosis is still lacking due to its elusive pathogenetic mechanism we registered that chitosan oligosaccharide (COS), a natural oligomer polysaccharide disgraced from chitosan, significantly rarefies I/R-geted AKI and maintains glomerular filtration function by curbing oxidative stress, mitochondrial damage, and excessive endoplasmic reticulum stress both in vitro and in vivo. In  Where to buy chitosan , long-term administration of COS can also attenuate the proliferation of myofibroblasts, mitigate extra cellular matrix deposition, and thus inhibit the transition of AKI to chronic kidney disease through participating in metabolic and redox biological appendages. Our determinations provide novel perceptivitys into the protective role of COS against acute kidney injury.Fabrication of magnetic chitosan-grafted salicylaldehyde/nanoclay for removal of azo dye: BBD optimization, characterization, and mechanistic study.

Herein, a novel nanohybrid composite of magnetic chitosan-salicylaldehyde/nanoclay (MCH-SAL/NCLA) was hydrothermally synthesised for removal of azo dye (acid red 88, AR88) from simulated wastewater. Response surface methodology compounded with the Box-Behnken design (RSM-BBD) was applied with 29 experiments to assess the impact of adsorption variables, that include A: % NCLA loading (0-50), B: MCH-SAL/NCLA dose (0-0 g/100 mL), C: pH (4-10), and time D: (10-90 min) on AR88 dye adsorption. The highest AR88 removal (75 %) as per desirability function was attained at the optimum stipulations (NCLA loading = 41 %, dosage = 0 g/100 mL, solution pH = 4, and time = 86. 17 min). The kinetic and equilibrium adsorption answers of AR88 by MCH-SAL/NCLA reveal that the process traces the pseudo-first-order and Temkin manakins. The MCH-SAL/NCLA composite has a maximum adsorption capacity (173 mg/g) with the AR88 dye. The adsorption of AR88 onto the MCH-SAL/NCLA surface is fixed by a variety of appendages, including electrostatic, hydrogen bonding, n-π, and n-π interactions.

This research breaked that MCH-SAL/NCLA can be used as a versatile and efficient bio-adsorbent for azo dye removal from contaminated wastewater.Synthesis of chitosan free-based shrinked graphene oxide-CeO(2) nanocomposites for drug delivery and antibacterial applications.In this study, the unique features of chitosan, reduced graphene oxide (rGO) and cerium oxide (CeO(2)) established hybrid bionano-composites make a carrier for various drug delivery and antimicrobial lotions. The recent lits expressed that addition of biopolymers to rGO and CeO(2) free-based nanocomposites exhibit excellent performance in design and development of biosensors, wound fertilizations, electrodes, microfluidic chips, drug delivery schemes and energy storage applications. Chitosan (CS), reduced graphene oxide (rGO) mixed with cerium oxide (CeO(2)) to form CS-rGO and CS-rGO-CeO(2) hybrid bionano-complexs applying precipitation method. The physiochemical characterization of vagabonded nanocomposite sheet was done practicing FTIR, XRD, UV-Vis spectrum, SEM and TGA. The XRD solvents of CS-rGO-CeO(2) divulged that the nanoparticle was geted to be crystalline structure.

FTIR unveiled that nitrogen functionalities of CS interacted with rGO-CeO(2) to form hybrid nanocomposites.  chitosan supplement benefits  (TGA) exhibited that the CS-rGO-CeO(2) has better thermal stability up to 550 °C. The SEM sustains the surface morphology of CS-rGO-CeO(2) has large surface area with smooth surface the antibacterial attributes of nanocomposites exhibit excellent zone of inhibition against Staphylococcus aureus and Escherichia coli. The NIH3T3 cell line evaluations depicted superior cell adhesion on hybrid nanocomposites.
