Introduction: Various iodine isotopes are undergoing radioactive decay except Iodine-127 (I-127. Iodine I-131 is unsealed radioactive material used in nuclear medicine for both diagnostic and therapeutic procedures in Royal Hospital since 2006. In radiotoxic classification, I-131 is in group 2 element. I-131 is highly reactive element due to its volatilization nature. Currently...

in this paper, a new approach for estimating the number of wideband sources is proposed which is based on rss or ism algorithms. numerical results show that the mdl-based and eit-based proposed algorithm havea much better detection performance than that in egm and aic cases for small differences between the incident angles of sources. in addition, for similar conditions, rss algorithm offers hi...

Considering the circulation of Bordetella pertussis clinical strains among populations with high vaccination coverage, it is necessary to have a proper understanding of this bacterium causing whooping cough. Various techniques, which are available for studying B. pertussis, can facilitate a proper comparison between different populations. We genotypically analyzed a collection of two vaccine st...

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...

introduction: vaccination has been the most effective human intervention in alleviating human sufferings and death. vaccine production in iran has a long history however, in the face of a changing global landscape, it requires a new roadmap for research, development and production in the coming decades. methods: this document was drafted based on article a of the “comprehensive national scienti...

the aim of this study was to prepare a new formula of leishmania major (l. major) crude antigen and evaluate its effect on immune system. for this purpose l. major promastigotes were cultured, harvested, washed, and resuspended in physiologic saline and the suspensions were dispersed in five equal batches. 0.1 ml of various doses of the cocktail antigen were injected intradermaly in three group...

in the present study the effect of the locally produced genetic adjuvant of ginea pig specific cpg-motif-containing oligodeoxynucleotide (cpg-odn) in an inactivated fmd virus vaccine was evaluated. boosting the ginea pigs with fmd vaccine along with cpg-odn adjuvant produced relatively higher ratio (5-fold) of fmdv-specific igg2a / igg1 than those vaccinated in the absence of cpg-odn. the neutr...

introduction and aims: in order to prevent liver cirrhosis and hepatocellular carcinoma in later life, it is essential to prevent hepatitis b virus (hbv) infection in infants. despite the availability of an effective vaccine, hepatitis b still continues to be a significant health problem. the aim of this study is to reveal the efficacy of passive and active immunoprophylaxis for preventing peri...
