BACKGROUND Hen's egg allergy is a frequent cause of childhood food allergy. Egg yolk is used in various commonly consumed foods; if children with allergy to hen's egg could eat heated egg yolk, their quality of life (QOL) would improve. No reports exist regarding oral food challenges (OFCs) for heated egg yolk. We aimed to clarify whether pediatric patients allergic to hen's egg could consume h...

The production of anti-snake venom from large mammal's blood has been found to be low-yielding and arduous, consequently, antivenom immunoglobulins for treatment are achieved regularly as polyvalent serum. We have standardized an undemanding technique for making purified immunoglobulin IgY antivenom consisting of polyclonal antibodies against coral snake venom in the egg yolk of immunized hens....

objective(s): 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; hypercholesterol...

tumor necrosis factor- α (tnf-α) plays an important role in diverse cellular events such as septic shock, induction of other cytokines, cell proliferation and apoptosis. tumor necrosis factor (tnf)-related apoptosis-inducing ligand (trail) is currently attracting great interest as a potential anticancer drug. trail could selectively induce apoptosis in tumor cells in vitro and in vivo by a deat...

A two-step chromatographic procedure was developed for the isolation and purification of hen IgY antibodies from egg yolk. The antibodies were completely separated from vitellin and lipids by hydrophobic interaction chromatography followed by gel filtration. Almost no residual yolk proteins, no immunoglobulin aggregates, and no antibody fragments could be detected in the final extract. Moreover...

Immunoglobulin Y (IgY) represents an important class of antibodies, being present in egg yolk, with relevant medical applications and involving non-invasive methods extraction. However, due to the complexity purification levels required for use most demands application multi-step cost-intensive techniques. Therefore, it is upmost importance develop a biocompatible cost-effective downstream proc...

Chicken egg yolk is a rich source of nutrients providing high quality proteins, vitamins, minerals, carotenoids and antioxidants. Chicken egg yolk, recovered from whole egg within 24 hours post-lay has been utilized as a starting material in the preparation of a dietary supplement that has been demonstrated to lead to gains in muscle mass in a human clinical study. Further, an oil derived from ...

Egg yolk oil is a natural source of bioactive compounds such as DHA, fat–soluble vitamins, lutein, phospholipids and cholesterol. These important compounds are also found in breast milk: DHA for infant brain development, lutein for eye health, vitamins A and E to support developing cells. Egg yolk oil naturally contains vitamin D which is required for a normal bone development. Fatty acid profi...
