Experiments by Parsons, Smith, Moise, and Mendel(1930), on the physiological effects of various protein-rich diets showed that cooked, dried, commercial egg whit,e is unsatisfactory for reproduction and lactation when fed to adult female rats as either 80 or 20 per cent of a well supplemented diet. Bond (1922) found that reproduct,ion was not optimum with 30 per cent of egg white in the ration,...

Chicken egg white protects the embryo from bacterial invaders by presenting an assortment of antagonistic activities that combine together to both kill and inhibit growth. The key features of the egg white anti-bacterial system are iron restriction, high pH, antibacterial peptides and proteins, and viscosity. Salmonella enterica serovar Enteritidis is the major pathogen responsible for egg-born...

The objective of this study was to develop a statistical model for predicting egg yolk contamination level in egg white using a spectroscopic method. Eggs that were stored for 0, 0.5, 1.0, 1.5, 2.5, and 6.5 wk at 4 C were manually processed to cleanly separate the yolk from the white. Egg white samples containing 0e0.5% (w/w) of yolk were prepared by adding yolk to the white and further dilutin...

this survey was done for constructing an egg sorting machine which could sort white eggs from fertilized eggs. egg sorting machine was constructed based on physiological properties of trout egg. fertilized eggs have much more elasticity than white or non-hatched eggs. so the hatched eggs will fly back if were hit to a solid surface. the machine divided to 5 parts including mechanical, electrica...

Several species of arthropods prey upon or utilize foam nests made by leptodactylid frogs. A spider [Lycosa pampeana) enters burrows made by Leptodactylus iatinasus in Argentina and eats most of the eggs. Two genera of dytiscid beetles have representatives that lay eggs on the foam mass Q^ Physalaemus pustulosas in Guatemala; beetle larvae hatch and swim in temporary ponds, where they feed on f...

PURPOSE Egg (egg white) allergies are among the most common food allergies in infants and young children. Serum egg white-specific IgE (sIgE) levels have been shown to be correlated with clinical symptoms, and the predictive decision point of sIgE levels has been proposed and used widely in the clinical setting. However, some patients whose sIgE levels to egg white are higher than the predictiv...

Egg white as a protein system possesses much interest, both biochemical and technological. Study of the egg white proteins has been handicapped by the difficulty of preparation. The five variant system developed by Cohn and coworkers for the fractionation of plasma offers many advantages over the salting-out techniques (1). Low temperatures are employed to improve protein stability. Since low s...

A 66-year-old man was admitted to our Department for a sudden loss of consciousness, tonic–clonic movement and psychomotor agitation. During the previous 4 months the patient had complained of drowsiness, fatigue, lack of appetite, and nausea. During the prior 2 months he had experienced hair loss, coating of the tongue, and skin flaking with pruritus. Two hours prior to admission, the patient ...

The objective of the study was to examine the activity of different biologically active proteins in geese egg whites. The experiment was performed in 8 replicates on eggs collected from Italian White geese, Polish wild geese (Gegawa) and their cross line. Analyses of activities of cystatin, lysozyme and serine proteinases inhibitors in fresh geese egg whites were carried out. Moreover, trypsin ...
