Eggs of the eucalyptus longhorned borer (Phoracantha semipunctata F.) are the typical host of the encyrtid egg parasitoid Avetianella longoi Siscaro. Both P. semipunctata and Phoracantha recurva Newman have become established in California, but A. longoi appears to differentially parasitize these congeners. Eggs of the two beetle species were tested for ovipositional and developmental suitabili...

Brown eggs have gradually entered the traditional white-egg markets as a distinctive mode for packaging specialty eggs. A test was conducted at the Brigham Young University Sensory Laboratory (Provo, UT) to understand how consumers view attributes of the brown egg relative to the white egg. The objectives were to see how the consumer viewed properties of eggs by color and to examine the prefere...

BACKGROUND For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy. METHODS In this double-blind, randomized, placebo-controlled study, 55 children, 5 to 11 years of age, with egg allergy received oral immunotherapy (40 children) or placebo (15). Initial dose-escalation, ...

BACKGROUND Hen and quail eggs are commonly used in embryological research. While immunoglobin E (IgE)-associated allergy to hens' egg proteins is recognized in employees in the food industry, there are no previous reports from workers in embryological research. Two newly identified cases prompted us to examine the extent of this problem in a university laboratory. AIMS To determine the preval...

Methods Seven children aged 9 months to 6.6 years (median 1.7 years) with hen’s egg allergy were performed open oral food challenge tests with boiled hen’s egg to define the threshold dose. Subjects underwent SOTI in which they intake boiled hen’s egg at home 3 days every week. The dose was increased every 1 to 2 weeks from approximately one fourth of the threshold dose to 60g. Clinical respons...

Human sera obtained from children with egg allergy reacted well with both native and heated ovomucoid (OM). Ovalbumin is present in egg white in a 5 times greater quantity than OM; however, it easily aggregates and becomes difficult to extract by heating. For accurate food allergen labeling of processed food, therefore, OM should be evaluated with the determination of egg white protein in consi...

Resolution of egg allergy occurs in the majority of egg allergic children. Positive specific IgE antibodies to ovomucoid (OVM) have been suggested to be of greater predictive value for persistent egg allergy than specific IgE to egg white. The performance of OVM-specific IgE antibody levels in a cohort of children referred for a routine egg challenge was compared with egg white specific IgE lev...

Shared parasites can strongly influence the outcome of competition between congeneric, sympatric hosts, and thus host population dynamics. Parasite-mediated competition is commonly hypothesized as an important factor in biological invasion success; invasive species often experience lower infection levels and/or parasite-induced mortality than native congeneric hosts. However, variation in infec...

  The aims of the present study were to determine the best time for egg stripping after ovulation and to study oocyte over-ripening in the Caspian brown trout (Salmo trutta caspius). Eggs were retained in the female abdominal cavity for 40 days post ovulation (DPO). Partial volumes of eggs stripped from 10 individually identified females at 10 days intervals and fertilized with a pool of semen ...
