In this work, an efficient synthesis of bionanohybrids as artificial metalloenzymes (Cu, Pd, Ag, Mn) based on the application enzyme a scaffold was described. Here we evaluated effect changing metal, pH medium, and amount in these metalloenzymes, where changes metal species size nanoparticles occur. These nanozymes were applied degradation hydrogen peroxide for their evaluation mimetics catalas...

Catalase, an endogenous antioxidant enzyme, is thought to have rescue effects on hepatic fibrosis. In this study, the regulation of catalase in CCl₄-induced hepatic fibrogenesis was investigated. Our results indicated that catalase expression was decreased upon CCl₄ treatment in a time-dependent manner, while the expression of several profibrosis and proangiogenic factors, including transforming ...

The number of patients with end-stage renal disease is growing rapidly in Asia. Patients with end stage renal disease failure (ESRD) undergoing long term hemodialysis (HD) are at risk for high oxidative stress. There is paucity of information with regard to oxidative stress during HD. Therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...
