the aim of this experiment was to study the effect of in ovoinjection of royal jelly (rj) on growth performance and immune response in broiler chickens challenged with newcastle disease virus. a total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. the eggs were injected with sterilized sodium bicarbonate buffer (ph=10.4) or rj (88%) ...

a research study was conducted to evaluate the effects of three herbal extracts and an antibiotic –virginiamycin- on growth performance, immune system, blood factors and selected intestinal bacterial populations in broiler chickens. a total of four hundred and eighty 1-day old male broiler chicks were assigned to the basal diet (control) , basal diet supplemented with 15 ppm of virginiamyci...

introduction: the activity of hypothalamus-pituitary-adrenal (hpa) axis is increased following inflammation due to its closed relation with immune system. this axis indicates an increased secretion of acth, and corticosterone during acute inflammation while little is known about its activity during chronic inflammation such as rheumatoid arthritis (ra). in this study we measured the products of...

background: multiple sclerosis (ms), the most common demyelinating disease of the cns, is immunologically mediated in genetically susceptible individuals. receptors for the fc fragment of igg (fcγr) might induce inflammatory responses through linking the humoral and cellular immune responses by targeting immune complexes to effector cells. polymorphisms in some fcγr genes are associated with va...

the close relationship between the immune system and the central nervous system (cns) has been well-studied. the cns regulates almost all the functions of the immune system; however, the effect and/or the control of the immune system on the cns has not been well-studied yet. recent reports suggest that the cns has its own defence mechanism(s). in this review, attempts have been made to discuss ...

Idiopathic nephrotic syndrome is the most frequent glomerular disease in children. The mechanisms underlying its pathophysiology have been investigated by genetic, cellular and molecular approaches. While genetic analyses have provided new insights into disease pathogenesis through the discovery of several podocyte genes mutated in distinct forms of inherited nephrotic syndrome, the molecular b...

this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...

in the software development process, testing is one of the most human intensive steps. many researchers try to automate test case generation to reduce the manual labor of this step. negative selection is a famous algorithm in the field of artificial immune system (ais) and many different applications has been developed using its idea. in this paper we have designed a new algorithm based on nega...
