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...

cellular and molecular pathways link thrombosis and innate immune system during sepsis. extrinsic pathway activation of protease thrombin through fviia and tissue factor (tf) in sepsis help activate its endothelial cell (ec) membrane protease activated receptor 1 (par-1). thrombin adjusts the ec cycle through activation of g proteins (g12/13), and later through rho gefs (guanine nucleotide exch...

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...

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 ...

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...

background & aim: aflatoxin (af) is the most important fungus that contaminates food and feed and can enter the food chain of humans. the aim of this study was to investigate the ability of thistle seeds (silybum marianum l.) to reduce the adverse effects of aflatoxin b1 (afb1) on the immune system, variables related to the intestine, appearance and mortality of the broiler chickens. exper...

background: black seed (nigella sativa l.) in traditional medicine is well known that the chemical composition of the immune system with many applications in traditional medicine to fight the infection. this study investigated the effect of the plant's role in the immune system and blood protein. experimental: in this study male mice of balb/c strain were divided into four groups tested. contr...
