OBJECTIVE: The aim of this study was to evaluate the effect of good glycemic control on serum lipids levels and lipid peroxidation, and to find out the relationship between the level of malondialdehyde and HbA1c in type 2 diabetes. MATERIALS AND METHODS: Fifty type 2 diabetic patients aged 40-60 years with the history of diabetes for more than 10 years were studied. Glycemic control was stable...

This study evaluated the ability of fennel extract to improve the quality of refrigerated minced silver carp over a period of 16 days. Minced silver carp were treated with fennel extract (0.5, 1 and 1.5% w/w), and beta-hydroxy toluene (BHT 200 ppm). The control and the treated fish samples were analyzed periodically (every 4 days) by chemical analysis (Peroxide value (PV), thiobarbituric acid (...

Cardiovascular disease and osteoporosis together account for most of the morbidity and mortality in our aging population despite significant improvements in treatment. Recently, converging lines of evidence suggest that these 2 diseases share an etiologic factor--that hyperlipidemia contributes not only to atherosclerotic plaque formation, but also to osteoporosis, following a similar biologic ...

Lipid peroxidation (LPO) in cellular membranes is associated with changes in physicochemical properties and impairment of protein functions located in membrane environment. Recent studies shows involvement of LPO in biological signaling and various diseases. Lipids are oxidized by three distinct mechanisms: enzymatic oxidation; non-enzymatic, free radical-mediated oxidation and non-enzymatic, n...

The aim of this study was to investigate whether endurance training improves lipid mobilization and oxidation in overweight subjects. Eleven young men (25.6 +/- 1.4 yr and body mass index 27.7 +/- 0.2) performed a 4-mo training program consisting of practicing aerobic exercise 5 days/wk. Before and after the training period, lipid oxidation was explored during a 60-min exercise at 50% of peak O...

The chemolithoautotrophic bacterium, Acidithiobacillus ferrooxidans, commonly occurs in acid mine drainage (AMD) environments where it is responsible for catalyzing the oxidation of pyrite and concomitant development of acidic conditions. This investigation reports on the growth of this bacterial species on the pyrite surface and in the aqueous phase at a pH close to 2 as well as the role of ad...

To address potential mechanisms for oxidative modification of lipids in vivo, we investigated the possibility that phospholipids react directly with glucose to form advanced glycosylation end products (AGEs) that then initiate lipid oxidation. Phospholipid-linked AGEs formed readily in vitro, mimicking the absorbance, fluorescence, and immunochemical properties of AGEs that result from advanced...

The effect of high hydrostatic pressure (HHP) on reduced ingoing amounts both nitrate and nitrite (150, 75, 37.5, 0 mg/kg each curing salt) dry-cured loins during the refrigerated storage was studied. Changes in instrumental color, nitrosylmyoglobin (NOMb) Zinc protoporphyrin (ZnPP) contents, lipid protein oxidation were analyzed. reduction nitrate/nitrite decreased redness (CIE a*) NOMb conten...

Houmard JA. Intramuscular lipid oxidation and obesity. Am J Physiol Regul Integr Comp Physiol 294: R1111–R1116, 2008. First published February 6, 2008; doi:10.1152/ajpregu.00396.2007.—There is an accumulating amount of evidence indicating that lipid oxidation is depressed in the skeletal muscle of obese individuals. Decrements in fatty acid oxidation (FAO) have been reported with obesity in mod...
