Introduction: Tuberculosis (TB) has been considered as a main health problems of the present century. Unfortunately, it has been reported different protective responses against BCG vaccine, as only available vaccine against TB .The search for a new and improved vaccine against tuberculosis is currently a very active field of research. In this study, we have evaluated the relative effects of int...
Introdution: E. coli O157:H7 with its ability of quick implantation inside gastrointestinal tract that causes hemolytic uremic and bloody diarrhea in humans is an important subject to investigate. One of the effective ways to prevent these infections is using nanovaccines prepared from immunogenic recombinant protein from bacterial virulence factors. In this research, the chitosan encapsulated ...
Introduction: Covid-19 epidemic results from an infection caused by SARS-CoV2. Evolution-based analyses on the nucleotide sequences show that SARS-CoV2 is a member of the genus Beta-coronaviruses and its genome consists of a single-stranded RNA, encoding 16 proteins. Among the structural proteins, the nucleocapsid is the most abundant protein in virus structure, highly immunogenic, with sequenc...
Introduction: Vaccination with the major surface antigen of hepatitis B virus (HBsAg) induces anti-HBs antibody production and level of 10 IU/L is considered protective. It has been shown that the level of anti-HBs antibody does wane after vaccination. The aim of this study was to evaluate the persistence of anti-HBs antibodies in healthy Iranian children 10 years after primary vaccination. Me...
Background: Thalassemia patients are more susceptible to hepatitis than the normal population due to the frequent blood transfusions. Objective: To determine the immune response of children with major ß-thalassemia, by measuring anti-hepatitis B surface antibody (anti-HBs Ab) following the last HBV vaccine injection. Methods: This study was carried out on 215 thalassemic children who received t...
introduction: hepatitis c virus (hcv) infection is a major public health problem which influences about 170 million people worldwide. different types of vaccines have been designed using hcv structural proteins to control the viral infection. the core nucleocapsid protein is one of the most conserved proteins and a desirable target for hcv vaccines, especially the protein-based vaccines. in cur...
conclusion our findings confirmed that a prokaryotic expression system of rureb229-561 was successfully constructed.the results of sds-page showed that our constructed prokaryotic expression system pet28a- ureb229-561 -bl21de3 efficiently produces target recombinant protein in the form of dissoluble inclusion body. therefore we can suggest that these epitopes can effectively be a vaccine candid...
ricin, the toxic lectin extracted from the castor bean plant (ricinus communis), consists of an a chain (rta) and a b chain (rtb). anti-a chain abs and anti-b chain abs can neutralize toxins in vivo and in vitro via blocking the binding of the toxin to the cell. also, rtb protein is able to serve as an antigen deliver to the mucosal immune system and act as an immunoadjuant. here, the genomic d...
The sip gene encoding for a conserved highly immunogenic surface protein of Streptococcus agalactiae was amplified using polymerase chain reaction (PCR) and subcloned into prokaryotic expression vector pET32a (+) and expressed as a recombinant protein in E. coli BL21 (DE3). An indirect enzyme linked immunosorbent assay (ELISA) was developed using the purified Sip protein as a coating antigen, w...
This paper constructs an Impelling Technology Foresight Model (ITFM) for foreseeing impelling technology in the field of life science, which is a comprehensive model consisting of four class indicators: international scientific environment, evolving of papers and patents, collaboration features of patent assignees’ collaboration networks, and impacts. A case study was carried out in the field o...
