Hepatic mitochondrial and peroxisomal oxidative capacities were studied in young (4-5 weeks old) and adult (6-9 months old) lean and obese ob/ob mice that were fed or starved for 24 or 48 h. The adult obese mice showed elevated capacity for mitochondrial oxidation (ng-atoms of O consumed/min per mg of protein) of lipid and non-lipid substrates, with the exception of pyruvate + malate, and elevated activities of citrate synthase and total carnitine palmitoyltransferase. Oxidative rates and enzyme activities were not affected by starvation of lean or obese mice, and both males and females respon

Peroxidation of low-density lipoprotein (LDL) lipid is generally thought to represent the initial step in a series of modification reactions that ultimately transform the protein moiety of the lipoprotein into a form recognized by receptors different from those that bind native LDL. Uptake of LDL via these alternative receptors can lead to the formation of lipid-laden cells, which are typical for the early stages of atherogenesis. We have studied the oxidative modification of LDL by hypochlorite (-OCl), a powerful oxidant produced from H2O2 and chloride via the action of myeloperoxidase which

Although glucose is the main energy substrate, in its absence, lipid metabolism becomes the primary source of energy.

Glioblastoma (GBM) is the most common form of primary malignant brain tumor (45.6%), with an incidence of 3.1 per 100,000.

The objective of this study was to evaluate the effect of UV irradiation on chitosan's antioxidant activity using the ABTS assay and its inhibition of lipid oxidation in ground pork through the TBA assay. Chitosan was obtained from lobster chitin (<em>Panulirus argus</em>) through a thermo-alkaline N-deacetylation process. Six treatments were applied at different times (5, 15, and 30 min) and two wavelengths (254 and 365 nm). A sample of non-irradiated chitosan was used as a comparison standard. The chromatic coordinates of the chitosan solutions were also determined. UV irradiation of chitosa

This study investigated the influence of dietary astaxanthin (AX) on glucose and lipid metabolism in rainbow trout liver. Two iso-nitrogenous and iso-lipidic diets were tested for 12 weeks in rainbow trout with an initial mean weight of 309 g. The S-ASTA diet was supplemented with 100 mg of synthetic AX per kg of feed, whereas the control diet (CTRL) had no AX. Fish fed the S-ASTA diet displayed lower neutral and higher polar lipids in the liver, associated with smaller hepatocytes and lower cytoplasm vacuolization. Dietary AX upregulated adipose triglyceride lipase (atgl), hormone-sensitive l

During the 4 h after glucose ingestion the plasma insulin concentration increased by 33 +/- 4 microU/ml and this was associated with a significant increase in carbohydrate oxidation and decrement in lipid oxidation.

High-density lipoprotein (HDL) has been proposed as the principal carrier of hydroperoxides in plasma, based upon data gathered with an HPLC-chemiluminescence technique. To test this hypothesis we have measured total lipid hydroperoxides in native plasma using the ferrous oxidation in Xylenol Orange (FOX) assay and then fractionated plasma into very-low-density lipoprotein, low-density lipoprotein (LDL) and HDL fractions. Hydroperoxides were found to accumulate principally (more than 65%) in LDL, as judged by hydroperoxide content per amount of protein or cholesterol, or expressed as a proport

Concerns about global warming, fossil-fuel depletion, food security, and human health have promoted metabolic engineers to develop tools/strategies to overproduce microbial functional oils directly from renewable resources. Medium-chain fatty acids (MCFAs, C8–C12) have been shown to be important sources due to their diverse biotechnological importance, providing benefits ranging from functional lipids to uses in bio-fuel production. However, oleaginous microbes do not carry native pathways for the production of MCFAs, and therefore, diverse approaches have been adapted to compensate for the re

The influence of the technological process on true retention rate of EPA and DHA, indicators of lipid oxidation and physical properties, of canned smoked sprat in oil was investigated. It was assumed that the double dose of heat during the technological process (smoking/sterilization) can significantly affect the quality of lipids.
