Sequence similarity between the Drosophila segment polarity protein Armadillo and the vertebrate adherens junction protein beta-catenin raised the possibility that adherens junctions function in transduction of intercellular signals like that mediated by Wingless/Wnt-1. To substantiate the sequence similarity, properties of Armadillo were evaluated for consistency with a junctional role. Armadi...

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...

elevated amount of the free radicals due to ionizing radiation causes deteriorating damage on immune system. therefore, we made attempts to investigate the protective effect of vitamin e (vit-e), a biological antioxidant in balb/c mice, so as to find an affordable prophylactic supplementation for individuals who are at risk. several groups of mice were selected and exposed to sub-lethal g -irra...

mastitis is a one of the major diseases of dairy animals. staphylococcus aureus is the most common microorganism associated with this dairy scourge. cure rates of mastitis associated with this pathogen are appallingly low. biofilm is an important virulence factor and immunogenic structure of s. aureus that makes it resistant to phagocytosis and antibiotics. reports on the efficacy of vaccine pr...

this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...

the prevalence of hepatitis c virus (hcv) is approximately 3% around the world. this virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. the effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. hence, generating new vaccines or drugs is an obligation. however, there is no vaccine available for clinical u...
