Background: The influenza virus is one of the most important factors for higher morbidity and mortality in the world. Recently, researchers have been focused on influenza conserved antigenic proteins such as hemagglutinin stalk domain (HA2) for vaccine production and serological studies. The HA2 plays a major role in the fusion of the virus with host cells membrane. The immunity system enables ...
background: pandemic flu had at least two waves in iran. knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. as of december 30, 2009, a total of 3672 confirmed cases of human infection with a novel influenza a (2009 h1n1) virus had been reported in iran with 140 deaths. objective: in this study we aim to measure,...
Platelets contain a pool of endogenous adhesive proteins that can be released and may bind to surface membrane receptors under appropriate conditions. Because the binding of exogenous fibrinogen to platelets was shown previously to be accompanied by a time-dependent decrease in fibrinogen accessibility t o antibody and enzymes, studies were performed t o evaluate changes in the expression of en...
[Comparative assessment of the characteristics in various assay kits for prostate specific antigen].
Six kinds of assay kits based on different detecting principle for PSA were evaluated. Polyclonal antibody was used in 2 kits (Eiken, Markit-F) and monoclonal antibody in 4 kits (Ball Elsa, Delfia, Markit-M, Tandem-R). To evaluate their characteristics, sera of 12 female patients, 5 prostatectomized patients and 2 high stage prostate cancer patients were measured by these kits. On the female se...
Attempts were made to identify the non-Ig lymphocyte receptor responsible for B-cell induction by antigen and polyclonal B-cell activators (PBA). As a first step, the role of C'3 and Fc receptors was analyzed. It was shown that complement could be fixed onto B cells to such an extent that the lymphocytes could not bind complement-coated red cells, but this did not result in induction of polyclo...
