Abstract Background and objectives: The aim of this study was the detection of S.pneumoniae infection by rapid urinary test and blood culture in children with pneumonia in comparison with healthy children. Material and Methods: This case control study was carried out in pediatric ward of Rasoul Akram hospital in Tehran, Iran (2006 - 200٧).Fifty-four Community acquired pneumonia (CAP) and 50 hea...
Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...
Following single intravenous injections of a foreign protein antigen, bovine gamma-globulin, into mice and rabbits, antigenic material persisting in the liver could be detected for several weeks. Ground liver tissue-taken from the mice and rabbits, just mentioned, either 4 or 6 weeks after injecting the antigen-when transferred repeatedly, at 2 or 3 day intervals, to the peritoneal cavities of ...
The growth characteristics of an oncogenic simian adenovirus, SV20, in rhesus monkey (RhMK) and hamster kidney (HamK) cell cultures were compared. The ad sorption rate of SV20 in both cell systems was rather slow, but increased steadily up to 6 hr. There was 3 to 8 times more cell-associated virus in RhMK cells than in HamK cells during the first 6 hr of infection. A complete growth cycle of SV...
Background: Targeting of CD20 antigen with monoclonal antibodies has become the mainstay in the treatment of non-Hodgkin's lymphomas and immunotherapeutic depletion of malignant B cells. Accessibility of antigen is one of the crucial factors in development of monoclonal antibodies against this antigen. One major problem in expression of full length CD20 is aggregation and misfolding. Therefore,...
