KEY FINDINGS: Chitosanization with/without PEGylation examined to selectively enhance Tam-release at the cancerous-acidic micromilieu. Cytotoxic activity study demoed that Tam-adulterated PEGylated niosomes had a lower IC(50) value on MCF-7 cell line (0, 0, and 0 sentences) than Tam-loaded PEGylated chitosomes, Tam-adulterated niosomes, and Tam-adulterated chitosomes, respectively. Cell cycle analysis designated that PEGylation and/or Chitosanization significantly impact Tam efficiency in inducing apoptosis, with a preferential influence of PEGylation over chitosanization. The assay of Annexin-V/PI double staining unveiled that chitosanized-nanocarriers had a significant role in increasing the incidence of apoptosis over necrosis. Besides, PEGylated-nanocarriers increased apoptosis, as well as total death and necrosis percentages more than what was indicated from free Tam the average alterations in both Bax/Bcl-2 ratio and Caspase 9 were best meliorated in cellphones processed by Tam-loaded PEGylated niosomes over all other conceptualizations. The in-vivo study necessitating DMBA-stimulated-breast cancer rats revealed that PEGylation made the highest tumor-growth inhibition (84 %) and breast tumor selectivity, while chitosanization had a lower accumulation tendency in the blood (62 ng/ml) and liver tissues (103 ng/ml).

The histopathological specimens from the group handled with Tam-loaded PEGylated niosomes evinced the best improvement over other conceptualizations All these terminations closed the crucial effect of both PEGylation and chitosan-functionalization of Tam-laded niosomes in raising effectiveness, targetability, and safety.Zinc sulfide-chitosan hybrid nanoparticles as a robust surface for immobilization of Sillago sihama α-amylase.In the present study, zinc sulfide-chitosan hybrid nanoparticles synthesized by chemical deposition were used as a matrix for the immobilization of purified α-amylase evoked from Sillago sihama (Forsskal, 1775). In this regard, the size and morphological structure of zinc sulfide-chitosan hybrid nanoparticles before and after the stabilization process were appraised habituating FT-IR, DLS methods, as well as SEM and TEM electron microscopy, and EDS examines the efficiency of the immobilized enzyme was measured in terms of temperature, optimal pH, stability at the critical temperature, and pH values. Immobilization of α-amylase on zinc sulfide -chitosan hybrid nanoparticles increased the long-term stability, as well as its endurance to critical temperatures and pH values; however, the optimal temperature and pH values of the enzyme were not falsifyed tracing the immobilization process. The kinetic parameters of the enzyme were also interchanged during immobilization. Enzyme immobilization increased the K(m), whereas decreased the catalytic efficiency (K(cat) / K(m)) of the immobilized enzyme likened with the free enzyme.

These consequences are very important as, in most typefaces, enzyme immobilization thins the activity and catalytic efficiency of enzymes. The nano-enzyme raised in this study, due to its high temperature, and pH stability, could be a good candidate for industrial lotions, especially in the food industry.Tannic acid-crosslinked O-carboxymethyl chitosan hydrogels for enhanced antibacterial activity and rapid hemostasis.Bacterial infection and massive blood loss are major challenges for global public health a series of tannic acid capsulised O-carboxymethyl chitosan (CMC) established hydrogels were trained using a facile approach for both hemorrhage control and effective anti-bacterium. The solutions suggested that the tannic acid-cosslinked CMC hydrogels had excellent mechanical property, welling ability as well as great cytocompatibility with increasing tannic acid loading, the bleeding control and antibacterial performance against both E. coli and S. aureus were improved simultaneously, especially for the 5% tannic acid-cosslinked CMC hydrogel the developed CMC hydrogel loading with tannic acid could induce hemocytes and thrombocytes aggregation, promote the blood clotting and achieve bleeding control in vivo due to the complected fibrous web structure and the chemical activation (the phenol group of tannic acid).
