Functionalized Core-Shell Yttrium Oxide Nanoparticles as Antioxidants Agents in Heat Stressed Rats

Biol Trace Elem Res. 2020 Nov;198(1):189-197. doi: 10.1007/s12011-020-02036-8. Epub 2020 Feb 5.

Abstract

Herein, we assess the antioxidant potential of core-shell yttrium oxide nanoparticles functionalized with ethylene glycol methacrylate phosphate (EGMP). The antioxidant properties of these nanoparticles were investigated in heat stressed models of 21 rats (heat stressed group, group B). Different samples of blood, serum, and tissue homogenate were collected at different time intervals in order to measure oxidative biomarkers such as enzymatic antioxidants (SODs, GPX, GST, GR, and TAC) and oxidative byproducts (MDA, PC, and 8-OHdG). Liver specimens of prophylactic group and heat stressed ones were also histopathologically examined 2 h post NPs injection. The measurements of oxidative biomarkers were complementary with histopathological findings and confirmed the antioxidant properties of poly EGMP yttrium oxide NPs.
