PURPOSE: Eggs are highly nutritious but concerns over their cholesterol content have led to dietary avoidance among many. There are also important international differences in relevant dietary guidance. We conducted the first prospective study in China investigating the association of egg consumption, cardiovascular disease (CVD) mortality, and a meta-analysis. METHODS: We included 28,024 participants without CVD at baseline (2003-8) in Guangzhou Biobank Cohort Study...

1. A study was conducted to determine the effects of dried broccoli floret (DBF) on egg production parameters, egg quality, and apparent nutrient digestibility of laying hens. It was hypothesised that feeding DBF can improve egg quality without adversely affecting layer performance. 2. Seventy-two White Leghorn layers aged 62 weeks were randomly allotted to four dietary treatments (six cage replicates with three hens each) and fed diets containing 0, 40, 80, and 120 g/kg DBF in feed for 56 d. 3. Inclusion of DBF had no effect on feed intake, egg production, feed conversion ratio or egg components...

Phenanthrene is a low molecular weight polycyclic aromatic hydrocarbon (PAH) that is composed of three fused benzene rings. PAHs are formed naturally through incomplete combustion of organic materials, and are environmental contaminants due to anthropogenic activities (e.g. oil extraction and refining, industrial and municipal effluents, fossil fuel burning). Fish exposed to PAHs such as phenanthrene have been reported to exhibit altered reproductive axis endpoints, however the mechanisms that underlie these responses are not fully characterized...

The relationship between blood cholesterol and heart disease is well-established, with the lowering of serum low-density lipoprotein (LDL)-cholesterol being the primary target of preventive therapy. Furthermore, epidemiological studies report lower risk for heart disease with higher concentrations of high-density lipoprotein (HDL)-cholesterol. There has also been considerable interest in studying the relationship between dietary cholesterol intake and heart disease risk. Eggs are one of the richest sources of cholesterol in the diet...

Phospholipids have been shown to modulate intestinal cholesterol absorption in cells and animals, a process that is regulated by several transporter proteins. Of these proteins, Niemann-Pick C1-Like 1 (NPC1L1) is a major contributor to this process. The mechanism by which phospholipids modulate cholesterol absorption remains unknown. Here, we evaluate the effects of egg-yolk phospholipids on cholesterol absorption and transport in human colon carcinoma cell line (Caco-2 cells) and on the expression of NPC1L1 and others proteins associated with cholesterol absorption (ABCG5, ABCG8, ABCA1, ACAT2, MTP, CAV-1, ANX-2)...

Tick infestation in cattle reflects the main cause of economic loss to cattle producers. This is due to several reasons but mainly to their ability to feed on blood and generate a huge amount of eggs. Lipid transport in arthropods is achieved by highly specialized hemolymphatic lipoproteins, which resemble those described in vertebrate blood. Such lipoproteins continuously deliver lipids through the blood to growing eggs. The injection of radioactive [3 H] palmitic acid into tick hemocoel showed that the gut, ovary, fat body and Gene's organ were the main organs of incorporation of this labeled fatty acid...

ABSTRACTS Eggs are highly nutritious food whose high cholesterol content has been always an inconvenience due to concerns about the relationship between dietary cholesterol and atherosclerotic cardiovascular risk. As this remains uncertain, low cholesterol intake is recommended. This review deals with the techniques employed to reduce the cholesterol content in egg yolk once the egg is shelled. There are four main techniques: i) solvent extraction, ii) fractionation by centrifugation, iii) cholesterol chelates or adsorbents and iv) cholesterol biotransformation...

Atherosclerosis is a major cause for cardiovascular diseases. High-density lipoprotein (HDL) may reduce atherosclerosis through several different mechanisms. HDL is composed of lipids, cholesterol, cholesteryl esters, triglycerides, and phospholipids, mainly phosphatidylcholine plus specialized proteins called apolipoproteins (apos). In this study, we prepared vitamin E containing HDL (VE -HDL) that contains egg phosphatidylcholine, cholesterol, vitamin E, and two kinds of recombinant human apolipoproteins (rhapo)-rhapoA-I and rhapoE in vitro by the facilitation of cholate...
