Effects of lipid removal on the fine milling and air classification processing of oats were studied. Lipid removal by supercritical carbon dioxide (SC-CO2) extraction enabled concentration of the main components of oats e starch, protein, lipids and cell walls e into specific fractions. Using defatted oats as raw material, the highest b-glucan concentration of the cell wall-enriched fraction wa...

Insulin interaction with BLM with incorporated fragments of rat liver plasma membranes, containing hormone receptors, was studied by determining Young modulus of elasticity of bilayer lipid membranes in direction perpendicular to the surface, E. The presence of membrane proteins in a concentration of 60 micrograms.ml-1 induced a significant decrease in parameter E (to approx. 50%) as compared w...

Recently we have shown that the free energy for pore formation induced by antimicrobial peptides contains a term representing peptide-peptide interactions mediated by membrane thinning. This many-body effect gives rise to the cooperative concentration dependence of peptide activities. Here we performed oriented circular dichroism and x-ray diffraction experiments to study the lipid dependence o...

Background. Intravenous lipid emulsion (ILE) is recommended as a "rescue" treatment for local anaesthetic (LA) toxicity. A purported mechanism of action suggests that lipophilic LAs are sequestered into an intravascular "lipid-sink," thus reducing free drug concentration. There is limited data available correlating the effects of ILE on LAs. Aims. To compare the in vitro effect of ILE on LA con...

I. The micro-iodimetric method has been used to study some factors affecting the concentration of lipid peroxides in the adipose tissue of vitamin E-deficient rats. 2. Cod-liver oil methyl esters (CLOME) or maize oil methyl esters (MOME) with peroxide values ranging from 3 to 330p-equiv.lg were given by mouth to vitamin E-deficient rats deprived of food before and after the dose. Lipid peroxide...

The effect of alveolar oxygen tension on lung lipid peroxidation during lung ischemia was evaluated by using isolated rat lungs perfused with synthetic medium. After a 5-min equilibration period, global ischemia was produced by discontinuing perfusion while ventilation continued with gas mixtures containing 5% CO2 and a fixed oxygen concentration between 0 and 95%. Lipid peroxidation was assess...

background: the lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. the purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (mda) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. in addition, correlation of lipid peroxidation with mot...

The Vitamin E (VE) effect was examined on oxidative damage to DNA, lipids, and protein in mice that were fed various levels of lipid diets after total body irradiation (TBI) with X-rays at 2 Gy. No increase of 8-hydroxydeoxyguanosine (8OHdG) by TBI was observed in the + VE group; however, in the case of the -VE group, a significantly higher 8OHdG level was observed in the high-lipid group than ...

Much of our understanding of energy metabolism in the pig has been derived from studies in which the energy supply was controlled through regulated feed intake. In commercial situations, where ad libitum feeding is practiced, dietary energy concentration, but not daily feed intake, is under producer control. This study evaluated the interactive effects of dietary energy concentration and feedin...
