A new type of globular particle, the 'insoluble yolk globule', was isolated from the egg yolk of three avian species (hen, duck, and emu) by centrifugation or gel-filtration chromatography. These globules are stable in NaCl and urea solutions at concentrations that dissolve or disrupt other constituents of yolk, The isolated globules are about 1% of the dry yolk of hen's and duck's eggs but abo...

In this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of Leghorn-type laying hens (Hy-Line W-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. The treatment groups were: 1) Control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

Micellar, discoidal complexes of human apolipoprotein A-I (apo A-I) with phosphatidylcholines and cholesterol, prepared by the method described in the preceding paper (Matz, C. M., and Jonas, A. (1982) J. Biol. Chem. 257, 4535-4540), were used as substrates for human lecithin cholesterol acyltransferase, purified 10,000-fold. The micellar complexes of apo A-I.egg yolk-phosphatidylcholine.choles...

OBJECTIVES Atherosclerosis is the main leading cause of cardiovascular diseases. The purpose of this study was to assess the potential preventive effect of egg yolk HDL on the atherosclerosis plaque formation. MATERIALS AND METHODS Thirty rabbits were divided into five groups: A; normal diet, B; hyper-cholesterolemic diet, C; hypercholesterolemic + 400 mg/kg egg yolk HDL D; hypercholesterolem...
