Background: Paraoxonase-1 (PON1) is one of the HDL-associated proteins which contributes to the antioxidant properties of these lipoproteins. The aim of this pilot study was to evaluate the effect of the nutritional supplement ALAnerv® on serum PON1 activity in post-acute stroke patients undergoing rehabilitation. Methods: We enrolled 28 post-acute stroke patients and randomly divided them into...

OBJECTIVES To examined whether serum paraoxonase (PON1) and arylesterase (ARE) activities are correlated with inflammatory biomarkers (procalcitonin and high sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS). METHODS This cross-sectional study was conducted at the Departments of Cardiology and Biochemistry, Uludag University School of Medicine, Bursa, Turk...

Statins (3-hydroxy-3-methylglutarylcoenzyme A reductase inhibitors), apart from lowering plasma cholesterol, modulate other processes involved in atherogenesis. Paraoxonase (PON), contained in plasma high density lipoproteins, protects plasma lipoproteins from oxidative damage and is a potentially atheroprotective enzyme. We investigated the effect of cerivastatin on oxidant-antioxidant balance...

Homocysteine (Hcy) is an accepted independent risk factor for several major pathologies including cardiovascular disease, birth defects, osteoporosis, Alzheimer's disease, and renal failure. Interestingly, many of the pathologies associated with homocysteine are also linked to oxidative stress. The enzyme paraoxonase (PON1) - so named because of its ability to hydrolyse the toxic metabolite of ...

To determine the causes responsible for a preferential decrease of paraoxonase activity, which has been observed in the serum of patients with cardiovascular diseases, the inactivation or inhibition of paraoxonase 1 (PON1) by various endogenous factors was examined using paraoxon or phenyl acetate as a substrate. When purified PON1 was incubated with various endogenous oxidants or aldehydes, th...

Background and Aim: The aim of this study was to investigate the protective effects of Tanacetum parthenium extract (TPE) on lipid peroxidation and acute heart injury induced by carbon tetrachloride (CCl4) in rats. Materials and Methods: In an experimental study, 30 male Wistar rats were divided into 5 groups (n=6). Two of the groups were normal and damage control groups, other 3 groups were d...
