Lipid-associated ferritin from homogenates of guinea pig liver is released from its conjugate(s) by incubation with the non-ionic detergents Triton X-100 and Nonidet P-40 but not by incubation with the anionic detergent deoxycholate. The amount of lipid-associated ferritin released from its conjugate(s) depends on the concentration of the non-ionic detergents. At a final non-ionic detergent con...

Pediocin PA-1 bound to anionic lipid vesicles with saturated or unsaturated fatty acid chains in a lipid concentration-dependent fashion. Little change in binding parameters was observed for zwitterionic lipid vesicles. Decreasing the anionic lipid content of the vesicles gave a higher relative dissociation constant for the peptide-lipid interactions and further supports the electrostatic inter...

The aim of the research was to comparative study effectiveness synthetic antioxidants – lipid-soluble (butylated hydroxytoluene, BHT) and water–soluble (trolox) analogues vitamin E for cryopreservation Russian sturgeon sterlet sperm in presence modified Stein’s medium. ability phenolic reduce level lipid peroxidation sperm, beneficial effect on motility thawed has been shown. addition lipid- wa...

Microbial lipid production by the oleaginous yeast Cryptococcus sp. was studied using glucose and cellulosic hydrolysate as carbon source, to realize the feasiblility of biodiesel production from high-lipid cell culture. The crude lipid contents of Debaryomyces nepalensis and Cryptococcus sp. cultured in YM Agar reached as high as 32-35 % on dry weight basis, which were higher than those of Pse...

BACKGROUND Rising CO2 concentration was reported to increase phytoplankton growth rate as well as lipid productivity. This has raised questions regarding the NADPH supply for high lipid synthesis as well as rapid growth of algal cells. RESULTS In this study, growth, lipid content, photosynthetic performance, the activity, and expression of key enzymes in Calvin cycle and oxidative pentose pho...

Background Understanding whether the preceding low lipid profile leads to active tuberculosis (TB) or active TB leads to low lipid profile is crucial. Methods Lipid profile concentrations were determined from 159 study participants composed of 93 active TB patients [44 HIV coinfected (HIV+TB+) and 49 HIV negative (HIV-TB+)], 41 tuberculin skin test (TST) positive cases [17 HIV coinfected (HIV...

The phase stability of a fluid lipid bilayer composed of a mixture of DC(18)PC, (DSPC), and a shorter DCn(s) PC, with n(s) from 8 to 17, has been studied using a self-consistent field theory that explicitly includes molecular details and configurational properties of the lipid molecules. Phase separation between two liquid phases was found when there was a sufficient mismatch between the hydrop...

The combined effects of feeding time (morning and evening) and dietary fat concentration on feed intake, growth, body composition and lipid tissue distribution were examined in rainbow trout fed on demand. To that purpose, diets with low (LE, 6% lipid) or high energy concentrations (HE, 24% lipid) were used in four treatments that combined provision of the same (HE–HE or LE–LE) or different (HE...

A simple method for the rigorous derivation of lithogenic index or percent cholesterol saturation, embodying both relative and total lipid concentrations, is described. We recently demonstrated that under physiological conditions only two key physical-chemical variables, the bile salt-lecithin ratio and the total lipid (bile salts + lecithin + cholesterol) concentration determine the equilibriu...

Plasma FFA oxidation (measured by infusion of 14C-palmitate) and net lipid oxidation (indirect calorimetry) are both inhibited by insulin. The present study was designed to examine whether these insulin-mediated effects on lipid metabolism resulted from a decline in circulating FFA levels or from a direct action of the hormone on FFA/lipid oxidation. Nine subjects participated in two euglycemic...
