Background & Aims of the Study: Serum paraoxonase (PON1) is a potent antioxidant that is associated with the pathogenesis of several diseases. Also, it is reported that environmental factors can modulate the PON1 activity. In this study, the association between the Organophosphates (OP) exposure and plasma Paraoxonase/Arylesterase (PON1) activity and also OP-induced oxidative stress was investi...

Background: Recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. These findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. The present study was aimed to gain deeper ins...

The present study has examined the effect of elevated glucose levels on membrane lipid peroxidation and osmotic fragility in human red blood cells (RBC). Defibrinated whole blood or RBC were incubated with varying concentrations of glucose at 37 degrees C for 24 h. RBC incubated with elevated levels of glucose showed a significantly increased membrane lipid peroxidation when compared with contr...

objective: the effect of herbal medicine is more useful than synthetic medicines. the present research paper aims to show the effects of leaves extracts of zizyphus spina christi (zsc) on lipid profile, lipid peroxidation and activities of aminotransferase enzymes in streptozocin induced diabetic adult male rats. materials and methods: fifty six male rats weighing 150-200 gm were included in th...

tuberose (polianthes tuberosa l.) is an important commercial cut flower that has a short vase life. an experiment was carried out by using five different levels of humic acid (ha) (0, 25, 50, 75, and 100 mg l-1) and seven different levels of silver nano-particles (snp) (0, 0.5, 1, 2, 3, 4 and 5 mg l-1) mixed with 1.5% sucrose on cut tuberosa cv. single flower. the loss of fresh weight on third ...

Oxygen-derived free radicals such as hydroxyl and hydroperoxyl species have been demonstrated to oxidize membrane lipid components, mainly phospholipids, leading to lipid peroxidation. Membrane phospholipids containing polyunsaturated fatty acids are predominantly susceptible to peroxidation. Free radical catalyzed peroxidation of long chain polyunsaturated acids (LCPUFAs) such as arachidonic a...
