Effects of static and electromagnetic fields on human serum paraoxonase-1 activity in vitro
Introduction: In recent years the relationship between electromagnetic fields and coronary artery disease is attracted a considerable attention. Low density lipoprotein (LDL) oxidation is the initial step in the development of atherosclerosis. Paraoxonase1 (PON1) protects LDL and High density lipoprotein (HDL) against oxidative processes, thus preventing the formation of atherogenic (oxidized-L...
متن کاملParaoxonase 1 Activity, Lipid Profile, and Atherogenic Indexes Status in Coronary Heart Disease
Background: Dyslipidemia is considered an independent risk factor for coronary heart disease (CHD). In the present study, we examined lipid profiles and paraoxonase 1 (PON1) activity and atherogenic indexes status and the relationship of PON1 activity by high-density lipoprotein (HDL) and atherogenic indexes in CHD patients and healthy people. Methods: The aim of the study was to compare PON...
متن کاملبررسی پلیمورفیسم L55M ژن پاراکسوناز1 با ترکیب اسیدهای چرب فسفولیپیدهای موجود در لیپوپروتیینهای با دانسیته بالا
Background: Paraoxonase-1 (PON1) moves with high-density lipoprotein (HDL) particles in blood and prevents low-density lipoprotein (LDL) particles from oxidation. The aims of this study were to investigate the correlation between fatty acid composition of HDL phospholipids with pon-1 polymorphisms and response to lovastatin treatment in people with high blood cholesterol. Methods: In this desc...
متن کاملHuman paraoxonase-3 is an HDL-associated enzyme with biological activity similar to paraoxonase-1 protein but is not regulated by oxidized lipids.
Paraoxonase-1 (PON1) is a secreted protein associated primarily with high density lipoprotein (HDL) and participates in the prevention of low density lipoprotein (LDL) oxidation. Two other paraoxonase (PON) family members, namely, PON2 and PON3, have been identified. In this study, we report the cloning and characterization of the human PON3 gene from HepG2 cells. Tissue Northern analysis ident...
متن کاملEffects of heparin and dalteparin on oxidative stress during hemodialysis in patients with end-stage renal disease.
INTRODUCTION Dialysis-induced oxidative stress is one of the mechanisms of atherosclerotic changes. Heparin, used in hemodialysis, is an anticoagulant drug with anti-inflammatory and antioxidant effects. This study was planned in order to evaluate the antioxidant effects of heparin and dalteparin (low-molecular weight heparin). MATERIALS AND METHODS Twenty-two patients underwent 3 hemodialysi...
