Magnetic chitosan-silk fibroin hydrogel/graphene oxide nanobiocomposite for biological and hyperthermia coverings.This work presents a biocompatible magnetic nanobiocomposite cooked by the composition of chitosan (CS) hydrogel, silk fibroin (SF), graphene oxide (GO), and Fe(3)O(4) NPs. Terephthaloyl thiourea was gived as a cross-linking agent to cross-link the CS strings. The CS hydrogel/SF/GO/Fe(3)O(4) nanobiocomposite with many characteristics, such as high structural uniformity, thermal stability, biocompatibility, and stability in an aqueous solution. Various features of this novel magnetic nanobiocomposite were recognized by FT-IR, EDX, FE-SEM, XRD, TGA, and VSM analysis. The FE-SEM images were considered to evaluate the size distribution of the magnetic nanoparticles (MNPs) between 39 and 73 nm as well.

The performance of the prepared nanobiocomposite was valuated by the magnetic fluid hyperthermia process. Under the understudying magnetic field (AMF), the mean value of the specific absorption rate (SAR) was determined at 43 w/g.Anti-liver fibrosis activity of curcumin/chitosan-caked green silver nanoparticles.Liver fibrosis leads from the hepatic accumulation of the extracellular matrix companyed by a failure of the mechanisms responsible for matrix dissolution. Pathogenesis of liver fibrosis is consociated with many proteins from different cell characters. In the present study, in silico molecular docking analysis revealed that curcumin may inhibit the fibrosis-mediating proteins PDGF, PDGFRB, TIMP-1, and TLR-9 by direct binding.  benefits vitamin d3 -formulation can overcome curcumin troubles, increasing the efficacy of curcumin as a drug by maximizing its solubility and bioavailability, heightening its membrane permeability, and ameliorating its pharmacokinetics, pharmacodynamics and biodistribution green silver nanoparticles (AgNPs) were synthesized in the presence of sunlight by means of the metabolite of Streptomyces malachiticus, and surfaced with curcumin-chitosan mixture to serve as a drug delivery tool for curcumin to target CCl(4)-induced liver fibrosis mouse model.

Fibrosis induction significantly increased hepatic gene expression of COL1A1, α-SMA, PDGFRB, and TIMP1, lifted hepatic enzymes, increased histopathological determinations, and increased collagen deposition as specifyed by Mason's trichrome staining. Treatment with naked AgNPs inclined to increase these inflammatory results, while their coating with chitosan, similar to treatment with curcumin only, did not prevent the fibrogenic effect of CCl(4). The induction of liver fibrosis was reversed by concurrent treatment with curcumin/chitosan-coated AgNPs. In this nano form, curcumin was happened to be efficient as anti-liver fibrosis drug, asseverating the hepatic architecture and function during fibrosis development. This efficacy can be imputed to its inhibitory role through a direct binding to fibrosis-interceding proteins such as PDGFRB, TIMP-1, TLR-9 and TGF-β.Selenium-chitosan alleviates the toxic consequences of Zearalenone on antioxidant and immune function in mice.This study valued the protective effects of selenium-chitosan (SC) against antioxidant and immune function-touched damage rushed by zearalenone (ZEN) in mice.

In  d3 vitamin , 150 female mice were allotted to five groupings for a 30-day study. Control mice were fed a basal diet. Mice in the ZEN, ZEN-Se1, ZEN-Se2 and ZEN-Se3 radicals were fed the basal diet affixed with same dose of ZEN (2 mg/kg) and different doses of SC, 0, 0, 0 and 0 mg/kg, respectively (accounted by selenium). After 30 days, the total antioxidant capacity (T-AOC) level, glutathione peroxidase (GSH-Px) activity, total superoxide dismutase (T-SOD) activity and malondialdehyde (MDA) content in plasma and liver, as well as Con A-hastened splenocyte proliferation, plasma interleukins assiduitys and liver interleukin mRNA expression levels were determined.
