background: cadmium is an extremely toxic metal with ubiquitous environmental distribution. cadmium is a potent reproductive and developmental toxic agent, and intensive environmental exposure to this substance has been reported among the residents of tehran. in this study, we investigated the correlation between amniotic fluid cadmium levels and the risk of preeclampsia, prematurity and low bi...

The Egg Safety Action Plan released in 1999 raised questions concerning egg temperature used in the risk assessment model. Therefore, a national study was initiated to determine the internal and external temperature sequence of eggs from oviposition through distribution. Researchers gathered data from commercial egg production, shell egg processing, and distribution facilities. The experimental...

Determination of the avian influenza (AI) status of a flock has traditionally been done by detection of serum antibodies. However, for many diseases, detection of antibodies in egg yolk has been effective in monitoring the disease status of laying flocks. This study compared the utility of egg yolk vs. serum for determining AI status in laying hen flocks. Specific-pathogen-free white leghorn he...

Surface pressure (pi)-, surface potential (deltaV)-, and dipole moment (mu(perpendicular))-area (A) isotherms and morphological behavior were examined for monolayers of a newly designed 18-mer amphiphilic alpha-helical peptide (Hel 13-5), DPPC, and DPPC/egg-PC (1:1) and their combinations by the Wilhelmy method, ionizing electrode method, fluorescence microscopy (FM), and atomic force microscop...

a total number of  5520 female and  480 male breeders (arbor acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. there were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

BACKGROUND There is a paucity of data examining the natural history of and risk factors for egg allergy persistence, the most common IgE-mediated food allergy in infants. OBJECTIVE We aimed to assess the natural history of egg allergy and identify clinical predictors for persistent egg allergy in a population-based cohort. METHODS The HealthNuts study is a prospective, population-based coho...

OBJECTIVE To evaluate the comparative efficacy of 400 mg albendazole (Smith Kline Beecham) as a single dose and three brands of mebendazole (Janssen, Unibios and East African Pharmaceuticals) at doses of 100 mg twice a day for three consecutive days in the treatment of single or mixed infections with Ascaris lumbricoides and or Trichuris trichiura in four treatment groups of school children. ...

The flow in an elastico-viscous fluid between two co-axial infinite rotating porous discs is considered for high cross flow Reynolds number. The discs are rotating with different angular velocity and the injection rate of the fluid at one disc is different from the suction rate of other disc. The effect of suction parameters on the velocity components have been investigated numerically and solv...

A key prediction of theories of differential allocation and sexual conflict is that male phenotype will affect resource allocation by females. Females may adaptively increase investment in offspring when mated to high quality males to enhance the quality of their offspring, or males may vary in their ability to manipulate female investment post-mating. Males are known to be able to influence fe...

Abstract Egg rejection is an effective and widespread antiparasitic defense to eliminate foreign eggs from the nests of hosts brood parasitic birds. Several lines observational critical experimental evidence support a role for learning by in recognition versus own eggs; specifically, individual that have had prior or current experience with parasitism are more likely reject eggs. Here we confir...
