Background and purpose: Based on the epidemiologic studies, stroke has become one of the fundamental problems in the Middle East. Considering to the role of serum paraoxonase (PON1) in stroke, the present study designed to evaluate the prognostic importance of paraoxonase to arylesterase activity ratio (Para/Aryl) and ratios of the activities to HDL in nondiabetic patients with ischemic stroke....
Background: Arsenic as an environmental toxicant is able to induced oxidative stress. The present study aimed to evaluate of vitamin C supplementation on the paraoxonase1 (PON1) arylesterase activity (responsible for hydrolysing lipid-peroxides) in rat exposed to arsenic. Methods: The study was conducted in the Faculty of Veterinary Medicine, Tabriz Islamic Azad University, Tabriz, Iran in 2...
The complete amino acid sequence of human serum paraoxonase/arylesterase and the DNA sequence coding for that protein have recently been determined in two independent laboratories. There is now considerable evidence that the esterase exists in two genetically determined allozymic forms, and these A and B allozymes possess both paraoxonase and arylesterase activities. The B-type esterase has rel...
Introduction: Esterases (E.C. 3.1.1.) are widely distributed in nature and catalyze the hydrolysis of ester bonds. Arylesterases (E.C. 3.1.1.2.) show a preferential substrate specificity for aromatic esters. The mammalian arylesterases play important roles in the detoxification of organophosphorous compounds and are used as diagnostic indicators for liver cirrhosis. Very little is known about t...
Objective. In the present study, since PON1 is known as an HDL-associated antioxidant enzyme that inhibits the oxidative modification of LDL and oxidative stress plays a role in the pathogenesis of mesenteric ischemia, we investigated the changes in PON1 activity and lipid profile in an experimental ischemic colitis model. Methods. Forty male Wistar albino rats were divided into two groups: the...
