The role of lipids in providing energy and structural cellular components during vertebrate development is poorly understood. To elucidate these roles further, we visualized lipid deposition and examined expression of key lipid-regulating genes during zebrafish embryogenesis. We also conducted a semiquantitative analysis of lipidomic composition using liquid chromatography (LC)-mass spectrometr...
1. 31p NMR is a useful analytical technique for the study of the polymorphic phase behaviour of hydrated phospholipids in excess water. Such possibilities arise due to lateral diffusion of phospholipids which, in non-bilayer phases, produce additional motional averaging mechanisms. This results in distinctive 31p NMR spectra for lipids in the bilayer phase, hexagonal (Hll) phase, or phases such...
Sphingomyelin and cholesterol are membrane lipids that interact to form liquid-ordered phase believed to act as a platform for the organization of signaling proteins. We report analyses of synchrotron X-ray powder diffraction patterns recorded from aqueous dispersions of ternary mixtures of sphingomyelin and phosphatidylcholine from egg yolk and cholesterol to investigate how cholesterol distri...
Laying hens (Gallus gallus) are one of the poultries kept for their eggs. Eggs produced by chickens used as a source human food that contains lot nutrition and is affordable. also contain high levels cholesterol in yolk, so if consumed large quantities, they will pose risk disease. This study aims to determine effect giving probiotics early layer laying hen feed on high-density lipoprotein low-...
Abetalipoproteinemia, an inherited human disease characterized by a near-complete absence of the apolipoprotein (apo) B-containing lipoproteins in the plasma, is caused by mutations in the gene for microsomal triglyceride transfer protein (MTP). We used gene targeting to knock out the mouse MTP gene (Mttp). In heterozygous knockout mice (Mttp+/- ), the MTP mRNA, protein, and activity levels wer...
The aim of this study was to investigate the possibility to modificate the total lipid and cholesterol level, as well as fatty acid composition of egg yolks, by supplementing diets of laying hens with different fats. The trial was conducted in two six week experiments. Experiment I was conducted on 180 Isa Brown hens assigned to two age categories: 36 months old (O), and 27 weeks of age young (...
Cholesterol is required for fetal development. Data obtained from recent studies in humans, rodents, and cell cultures showed that circulating maternal cholesterol can affect fetal metabolism and sterol accretion. Recent studies in our laboratory showed that the efflux of cholesterol from the basolateral side of the placental cells and the secretion of cholesterol from endodermal yolk sac cells...
The effects on cholesterol metabolism in rats of diets containing various animal proteins or soy protein were studied. The animal proteins tested were casein, whey protein, fish protein, hemoglobin, plasma proteins, ovalbumin, egg-yolk protein, beef protein and chicken-meat protein. The semi-purified diets were isonitrogenous and balanced for residual fat and cholesterol in the protein preparat...
Citrullus colocynthis (CC) has been known as a natural medicinal plant with wide biological activities, including antioxidant, anti-inflammatory, and antilipidemic effects. The aim of this study was to investigate the effect inclusion ethanolic extract CC seeds (ECCs) into layer diets on lipid profile, stress indicators, physiological productive performance laying hens. A total 216 forty-week-o...
