Four types of bovine liver catalase (CAT) derivatives, succinylated (Suc-CAT), galactosylated (Gal-CAT), mannosylated (Man-CAT), and polyethylene glycol conjugate (PEG-CAT), were synthesized and their pharmacokinetics and therapeutic potential in a hepatic ischemia/reperfusion injury model were studied in mice. About 90% of the CAT enzymatic activity was retained after chemical modification. Bi...

Background: The aim of this study was to evaluate the possible protective effect of sodium selenite on serum, liver, and kidney antioxidant enzymes activities in alloxan-induced type 1 diabetic rats. Methods: Forty Sprague-Dawley male rats were randomly divided into four groups; Group one as control, Group two as sham-treated with sodium selenite by 1 mg/kg intraperitoneal (i.p.) injections ...

In the ongoing and polarized dialogue concerning the role of non-lethal management, including trapneuter-return (TNR), in managing community cats, reference is often made to studies that demonstrate that this approach does not work. This selected bibliography points to studies that, among others not summarized here, comprise a body of work that shows TNR as a valuable tool in managing cat popul...

In the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old Persian queen cat is described. In response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. Trans-abdominal ultrasonography examination showed 2 cysts  in the left ovary of the queen. Serum estrogen assay indicated elevated level o...

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...

In this paper, first we use an example to show the efficiency of $M$ iteration process introduced by Ullah and Arshad [4] for approximating fixed points of Suzuki generalized nonexpansive mappings. Then by using $M$ iteration process, we prove some strong and $Delta -$convergence theorems for Suzuki generalized nonexpansive mappings in the setting of $CAT(0)$ Spaces. Our results are the extensi...

Cataract is multi-factorial eye disease identified by the disturbance of the transparent ocular lens. There is significant evidence suggesting oxidative damage as a major cause of initiation and progression of numerous diseases including cataracts. NAD(P)H:quinone oxidoreductase 1 (NQO1; OMIM: 125860) and catalase (CAT, OMIM: 115500) are antioxidant enzymes that prevent cells from oxidative str...

reports indicate that one of the causes of harmful to the genital system, especially the testes is stress. result of damage to testicular quality certainly will affect the quality of sperm fertility. stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. one of the causes of stress could be scary voices, such as cat voice f...
