zinc (zn) is an essential trace element in all living organisms, and the first eukaryotic zn uptake transporter was discovered in the yeast, saccharomyces cerevisiae. zinc-enriched yeast is a currently available zn supplement. the purpose of the investigation was to compare and evaluate the effect of zn enriched yeast in rainbow trout. the fish (mean body weight 10 ± 0.5 g) were fed a commercia...

the present study was conducted to evaluate the efficacy of wood betony (wb), stachys lavandulifolia extract on growth performance and some immune responses in common carp, cyprinus carpio. different concentrations of the wb extract 0, 2, 4 and 8% (g per 100 g of diet) were added to commercial diet. each treatment was randomly assigned to triplicate groups of fish having average initial weight ...

background: alteration in peripheral blood lymphocytes (pbls) is usually investigated to provide an evidence of the host immune responses to tumor antigens. the tumor infiltrating nk cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. objective: to analyze peripheral blood and tumor associated natural killer (nk) cells in patients with breast ca...

Since Jules Freund reported that crude mycobacterial extracts greatly promoted immune responses to antigens (1), the use of adjuvants has become a widespread, but poorly understood practice to promote T and B cell responses (2). Recent studies have begun to identify the chemical nature of several adjuvants and the cellular and molecular mechanisms of their long-elusive immunologi-cal effects. F...

state immunity is considered to be one of the most important issues in contemporary international law. over time, this concept gas been changed due to the evolution of international law and during recent decades, the focus of academic forums and national and international courts has been attached to it. in the meantime, several states including i.r.iran and u.s.a have approved state immunity la...
