Antioxidant Activity of SOD and Catalase Conjugated with Nanocrystalline Ceria
Interactions of nanoparticles with biological matter-both somatically and in nature-draw scientists' attention. Nanoparticulate systems are believed to be our saviors, acting as versatile drug delivery vehicles. However, they can also cause life-threatening bodily damage. One of the most important properties of nanocrystalline cerium dioxide is its antioxidant activity, which decreases the abun...
متن کاملThe protective effects of cerium oxide nanoparticles against hepatic oxidative damage induced by monocrotaline
OBJECTIVE The objective of the present study was to determine the ability of cerium oxide (CeO(2)) nanoparticles to protect against monocrotaline (MCT)-induced hepatotoxicity in a rat model. METHOD Twenty male Sprague Dawley rats were arbitrarily assigned to four groups: control (received saline), CeO(2) (given 0.0001 nmol/kg intraperitoneally [IP]), MCT (given 10 mg/kg body weight IP as a si...
متن کاملGreen Synthesis of Nanoceria (CeO2) and Evaluation of Enzyme like Characteristics
In this study, the synthesis of ceria (CeO2) nanoparticles (NPs) was examined by the biosynthesis method. Then, enzyme-like features of synthesized nanoceria were examined. Peroxidase enzyme from fig (Ficus carica) was used as a synthesis and stabilizer reagent. Furthermore, it was investigated whether the obtained nanoceria has superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) ac...
متن کاملEffect of Cerium Oxide Nanoparticles on Oxidative Stress Biomarkers in Rats’ Kidney, Lung, and Serum
Background: The present study aimed to evaluate the effects of different concentrations of cerium oxide nanoparticles (CONPs) on the oxidative stress (OS) status in kidney, lung, and serum of rats. Methods: Male Wistar Rats were treated intraperitoneally with 15, 30, and 60 mg/kg/day of CONPs. The biochemical parameters, including total antioxidant capacity (TAC), total thiol group (TTG), malon...
متن کاملEffects of selected metal oxide nanoparticles on multiple biomarkers in Carassius auratus.
OBJECTIVE To study the biological effects of nanoscale copper oxide (nCuO), zinc oxide (nZnO), cerium dioxide (nCeO2) and their mixtures on Carassius auratus. METHODS Juvenile fish (Carassius auratus) were exposed to aqueous suspensions of nCuO, nZnO, and nCeO2 (alone and in mixtures) at concentrations of 20, 40, 80, 160, and 320 mg/L. The biomarkers-acetylcholinesterase (AChE) in brain, sodi...
