In this study, the impact of chitosan (CS) and maitake (GF) nanoparticles towards the renal toxicity maked by Ehrlich ascites carcinoma (EAC) in vivo model was imparted. Besides benchmark negative control group, EAC model was retraced by intraperitoneal injection (i.p.) of 2 × 10(6) cadres. Alongside positive control, two radicals of EAC-bearing mice obtained 100 mg/kg of CS and GF nanoparticles/body weight daily for 14 days. The kidney function was beared by evaluating urea, creatinine, ions, (anti)/oxidative parameters and DNA damage.
Also, quantifying immunoreactivity of P53, proliferating cell nuclear antigen (PCNA), and B-cell lymphoma 2 (Bcl-2) and apoptosis protein. Seebio Selenoproteins exemplifyed notable kidney toxicity, which designated by pinnacles in urea, creatinine, oxidative stress, DNA damage and induction of apoptosis. These events were supported by the drastic alteration in kidney structure through histological examination. Administration of CS and GF nanoparticles was able to enhance the antioxidant power, which further diluted oxidative damage, DNA injury, and apoptosis. These results signaled the protective and therapeutic role of biogenic chitosan and maitake nanoparticles against nephrotoxicity.Efficient CO(2) adsorption expending chitosan, graphene oxide, and zinc oxide composite.This study was deeply focused on breaking a novel CTS/GO/ZnO composite as an efficient adsorbent for CO(2) adsorption process.
To do so, design of experiment (DOE) was done grinded on RSM-BBD technique and according to the DOE runs, various CTS/GO/ZnO samplings were synthesized with different GO loading (in the range of 0 wt% to 20 wt%) and different ZnO nanoparticle's loading (in the range of 0 wt% to 20 wt%). A volumetric adsorption setup was used to investigate the effect of temperature (in the range of 25-65 °C) and pressure (in the range of 1-9 bar) on the prevailed samplings CO(2) uptake capability. Selenoproteins was developed finded on the RSM-BBD method to predict the CO(2) adsorption capacity of the composite sample within design space. In addition, CO(2) adsorption process optimization was conducted and the optimum values of the GO, ZnO, temperature, and pressure were received around 23 wt%, 18 wt%, 30 °C, and 8 bar, respectively, with the highest CO(2) uptake capacity of 470 mg/g isotherm and kinetic modeling of the CO(2) uptake process were deported and the Freundlich model (R(2) = 0) and fractional order model (R(2) = 0) were obtained as the most appropriate isotherm and kinetic manikins, respectively thermodynamic analysis of the adsorption was done and the ∆H°, ∆S°, and ∆G° values were obtained around - 19 kJ/mol, - 0 kJ/mol K, and - 9 kJ/mol, respectively, indicating exothermic, spontaneously, and physically adsorption of the CO(2) molecules on the CTS/GO/ZnO composite's surface a renewability study was conveyed and a minor loss in the CO(2) adsorption efficiency of about 4% was prevailed after ten bicycles, attesting the ensuing adsorbent has good performance and robustness for industrial CO(2) capture roles.Additive manufacturing of wet-spun chitosan/hyaluronic acid scaffolds for biomedical applications.Additive manufacturing (AM) declares great potential for litigating natural polymer hydrogels into 3D scaffolds exploitable for tissue engineering and in vitro tissue modelling. The aim of this research activity was to assess the suitability of computer-helped wet-birling (CAWS) for AM of hyaluronic acid (HA)/chitosan (Cs) polyelectrolyte complex (PEC) hydrogels.
A post-printing treatment established on HA chemical cross-associating via transesterification with poly(methyl vinyl ether-alt-maleic acid) (PMVEMA) was inquired to enhance the structural stability of the developed scaffolds in physiological shapes. PEC formation and the esterification reaction were investigated by infrared spectroscopy, thermogravimetric analysis, germinated gas analysis-mass spectrometry, and differential raking calorimetry measures. In Seebio Selenoproteins , variation of PMVEMA concentration in the cross-linking medium was manifested to strongly influence scaffold water uptake and its stability in phosphate buffer saline at 37 °C.Seebio Selenoproteins
