Using probiotics can control pathogens by a variety of mechanisms. Probiotics can promote growth performance and have, therefore, become increasingly important in the aquaculture industry. Convict Cichlid belongs to the family of Cichlidae and is known for its rapid development in laboratory conditions and is suitable for behavioral examinations. The aim of this study was to evaluate the effect...

The immunodominant, conformational "a" determinant of hepatitis B surface Ag (HBsAg) elicits Ab responses. We selectively expressed the Ab-binding, glycosylated, native a determinant (residue 120-147) of HBsAg in a fusion protein containing C-terminally the HBsAg fragment SII (residue 80-180) fused to a SV40 T-Ag-derived hsp73-binding 77 aa (T(77)) or non-hsp-binding 60 aa (T(60)) N terminus. A...

In recent years the diagnostic industry has developed new automated immunoassays for the qualitative detection of hepatitis B virus (HBV) surface antigen (HBsAg) in serum and plasma samples that are performed on analyzers that permit a high-speed throughput, random access, and primary tube sampling. The aim of the present study was the evaluation of two new automated HBsAg screening assays, IMM...

The diagnostic and prognostic value of pre-S(1)Ag and pre-S(2)Ab was investigated in 69 HBsAg surface antigen positive patients--14 with acute hepatitis B, 30 with chronic liver disease (six chronic persistent hepatitis, 14 chronic active hepatitis, 10 with cirrhosis) and in 25 asymptomatic carriers. Pre-S(1)Ag was found in all patients with chronic hepatitis B virus (HBV) infection regardless ...

the potential of heat inactivated saccharomyces cerevisiae in the bioremoval and reduction ofcr (vi) ions from wastewaters was evaluated in terms of metal uptake in time and at equilibrium, andbiosorption efficiency, by varying ph, biosorbent doses, contact time and temperature, in batch mode. during the sorption process, the heat inactivated biomass of the yeast saccharomyces cerevisiae is cap...

Pfsl6 is a sexual stage/sporozoite-specific antigen of Plasmodium falciparum and is a potential candidate for a sporozoite-neutralizing vaccine. To obtain more information on the function of Pfsl6 and to investigate its role during transmission and hepatocyte invasion, immunization experiments were performed with both a Pfs 16-specific recombinant vaccinia virus and virus-like particles produce...

The long surface antigen (L-HBsAg) of hepatitis B virus (HBV) plays a central role in the production of infectious virions. During HBV morphogenesis, both the PreS and S domains of L-HBsAg form docking sites for the viral nucleocapsids. Thus, a compound that disrupts the interaction between the L-HBsAg and nucleocapsids could serve as a therapeutic agent against the virus based upon inhibition ...

The performance of hepatitis B virus (HBV) surface antigen (HBsAg) screening assays is continuously improved in order to reduce the residual risk of transfusion-associated hepatitis B. In a multicenter study, a new automated rapid screening assay, Elecsys HBsAg (Roche Diagnostics), was compared to well-established tests (Auszyme Monoclonal [overnight incubation] version B and IMx HBsAg [Abbott]...

The aim of present study is investigating effect of treated lemon pulp by Saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. In this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by Saccharomyces cerevisiae yeas...
