We studied the influence of PON1 on metabolic alterations induced by oxidized LDL when incubated with endothelial cells. HUVEC cells were incubated with native LDL, oxidized LDL, oxidized LDL plus HDL from wild type mice, and oxidized LDL plus HDL from PON1-deficient mice. Results showed alterations in carbohydrate and phospholipid metabolism and increased apoptosis in cells incubated with oxid...

utilization of the new compatibilizers to improve matrix/filler interface adhesion and also, nanoparticles to improve the properties of wpc products have always been of interest to researchers. in this study, the effect of oxidized polypropylene in solution phase as a comptibilizer and nanoclay particles on the physical and mechanical properties of wood fiber reinforced polypropylene composite ...

BACKGROUND Increased levels of oxidized proteins have been reported in the serum of patients with end-stage renal disease, though little is known regarding the oxidized protein content of the dialysate in patients on peritoneal dialysis (PD) and no information is available as to how this may correlate with important clinical and laboratory variables, including abnormal peritoneal membrane funct...

The dimeric hemoglobin isolated from Scapharca inaequivalvis, HbI, is notable for its highly cooperative oxygen binding and for the unusual proximity of its heme groups. We now report that the oxidized protein, an equilibrium mixture of a dimeric high spin aquomet form and a monomeric low spin hemichrome, binds ferrocyanide tightly which allows for internal electron transfer with the heme iron....

Uptake of modified lipoproteins by resident arterial monocytes/macrophages is believed to be a key event in the formation of foam cells and thus in the early phases of atherosclerosis. Low-density lipoproteins (LDLs) that undergo oxidative changes become suitable for uptake by macrophages through a specific scavenger receptor that leads to cholesteryl ester accumulation. Because the interaction...

Aim of the study was to determine the usefulness of lipid profile& oxidized low density lipoprotein (LDL) in the identification of coronary artery disease (CAD) in Type 2 diabetes mellitus (T2DM) Lipid profile was estimated by using enzymatic methods and levels of oxidized LDL were measured by baseline diene conjugation method. Compared with control subjects, T2DM patients had higher levels of-...

Small samples from European aspen (Populus tremula L.) were impregnated with carbohydrates oxidized by Fenton’s reagent using water in a vacuum, followed by heating in an oven at 103 °C. An antiswelling efficiency (ASE) of around 45% for wood treated with oxidized glucose and 35% for wood treated with oxidized sucrose was obtained. Samples treated with oxidized carbohydrates gave water repellen...

Proinflammatory oxidized phospholipids are generated during oxidative modification of low-density lipoproteins (LDL). The production of these proinflammatory oxidized phospholipids is controlled by secreted enzymes that circulate as proteins complexed with LDL and high-density lipoprotein. During the acute phase response to tissue injury, profound changes occur in lipoprotein enzymatic composit...

In order to study the interaction of glutathione, vitamin C and vitamin E under hyperoxia (95 % oxygen) and hyperbaric oxygen (2.5 atmospheric pressure), 20 days old male Guinea pigs were fed with basal vitamin C free diet, while receiving a vitamin C supplement of either high concentration (50 mg/day) or low concentration (1 mg/day) for two weeks. Animals were than exposed to hyperoxia and hyp...
