background recommendations to immunize healthcare workers (hcws) against hepatitis b are well known. however, a proportion of individuals do not respond to the primary standard three-dose hb vaccination schedule. conclusions both the single- and double-dose hb vaccines were adequately immunogenic, and the double-dose hb vaccine was not significantly more immunogenic than the single-dose vaccine...

background: toxoplasma gondii is an obligate intracellular parasite that infects all mammalian cells. several antigens such as excreted/secreted antigens have been identified as a potential vaccine candidate. objective: to determine how excreted/secreted antigens from peritoneal exudates of infected mice (mesa) stimulate cell-mediated immune responses and induce protective immunity against toxo...

background and objective: presence of hepatitis b core antibody (anti-hbc) in the absence of hepatitis b surface antigen (hbsag) and hepatitis b surface antibody (anti-hbs) is defined, as isolated anti-hbc. little is known about the clinical significance of the isolated anti-hbc in hepatitis b virus (hbv) infections. the aim of this study was to assess the significance of anti-hbc as the only m...

ticks are important ectoparasites which are a considerable threat to human beings and to animals all overthe world. enormous economic losses annually occur in livestock production around the world as a result oftheir existance. one of the ways to control ticks and tick-borne diseases is to introduce resistance to theseectoparasites through immunization. for identification of the putative protec...

Transfusion medicine represents one of the emerging branches last century. With discovery isoagglutinin, main proof has been made that blood group inheritance is encoded in genes which established theory four groups. Moreover, presence certain antibodies, later known as Rh factors, directly reflects ability to accept or reject group. Several methods detection factor have used transfusion helps ...

background hepatitis b virus (hbv) is one of the most common chronic viral infections in the world. iran has a low to intermediate hbv prevalence and approximately 1.5 million people are living with hbv infection. the impact of hbv in iran is unknown and given the very low levels of alcohol consumption, this region provides an opportunity to examine the impact of isolated chronic hbv infection....

results there were 64 women and 936 men in the population under study. the mean ± sd age of the donors was 38 ± 11 years. 80 out of 1000 samples (8%) were found to be positive for hbcab. hbv dna was detected in 50% of hbcab positive specimens. the mean ± sd age of donors without hbv dna was 37.7 ± 10.5 years and for donors with hbv dna was 40.9 ± 11.2 years (p = 0.05). objectives the aim of thi...
