this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

PURPOSE To study the effect of modified frankfurters and pâtés: (a) reduced-fat products (RF) (15.3 and 15.2 % fat, respectively); (b) n-3-enriched reduced-fat products (n-3 RF) (15.1 and 15.5 % fat, respectively); and (c) normal-fat products (NF) (18 and 30.8 % fat, respectively) on lipids, lipoproteins, atherogenic ratios, oxidized LDL, and blood pressure of volunteers at high CVD risk. MET...

Background: Polyunsaturated fatty acids (PUFA) are found in nuts and seeds, salad dressings and vegetable oil and are prone to oxidation during storage and food preparation. Evidence supports that consumption of oxidized lipids promotes atherosclerosis and glucose intolerance in animal models. However there is a dearth of evidence with regard to the amount of oxidized lipids consumed and its as...

OBJECTIVE To assess the effects of dietary modifications on oxidized low-density lipoprotein (LDL). METHODS AND RESULTS Thirty-seven healthy women were fed two diets. Both diets contained a reduced amount of total and saturated fat. In addition, one diet was low in vegetables and the other was high in vegetables, berries, and fruit. The dietary intake of total fat was 70 g per day at baseline...

Paraoxonase is an enzyme associated with HDL in human serum that hydrolyzes oxidized phospholipids and inhibits LDL oxidation, which is an important step in atherogenesis. In animals, addition of oxidized lipids to the circulation reduces paraoxonase activity, and diets rich in oxidized fat accelerate the development of atherosclerosis. The current randomized, crossover study was designed to co...

PURPOSE To test the hypothesis that the accumulation of oxidized phospholipids (OxPL) in the macula is toxic to the retina unless neutralized by a variety of mechanisms, including binding by lipoprotein(a) [Lp(a)], which is composed of apolipoprotein(a) [apo(a)] and apolipoprotein B-100 (apoB). METHODS Human maculas and eyes from two Lp(a) transgenic murine models were subjected to morphologi...

OBJECTIVE We studied acute changes in markers of glycoxidative and lipoxidative stress, including oxidized LDL, N(epsilon)-(carboxyethyl)-lysine (CEL), N(epsilon)-(carboxymethyl)-lysine (CML), and 3-deoxyglucosone (3DG), following two consecutive meals. RESEARCH DESIGN AND METHODS Postmenopausal women (27 with normal glucose metabolism [NGM], 26 with type 2 diabetes) received two consecutive ...

The levels of oxidized serum lipoproteins are increased in humans and animals with diabetes. We have examined the contribution of dietary oxidized lipids on the levels of oxidized lipoproteins. In both control and streptozocin induced diabetic rats, the oxidized lipid content of mesenteric lymph chylomicrons (CM) increased when increasing quantities of oxidized lipids were administered intragas...
