background : mosquitoes are considered as the vectors of dirofilariasis and some vector borne disease in iran. the objective of this study was to determine the susceptibility level of the vectors to various insecticides recommended by who for any control measures in an endemic area in northwestern iran. methods : mosquito larval and adult collections were carried out using different methods pro...

background: cutaneous leishmaniasis is a major health problem in iran in spite of implementation of control pro­gram. this infectious disease caused morbidity in less than 27000 people in 2010. this study was set to determine some ecological aspects of sand flies in fasa district, fars province, southern iran during 2011–2012. methods: a total of 4792 sand flies were captured by means of sticky...

Background: The micro-ribonucleic acids (miRNAs) are noncoding RNA molecules that are conserved developmentally and include usually 18-25 nucleotides. MiRNA regulates gene expression through mRNA degradation or inhibiting of its translation. These biomolecules contribute in cellular physiologic and pathologic processes and most of them may act as oncogenes or tumor inhibitors. Identification of...

objective: in this project, our aim was to construct a novel expressing vector harboring a new sequence from overlapping region of ns3 gene of hcv from infected iranian patient. materials and methods: the partial ns3 (pns3) gene was amplified by nested-rt-pcr method using sera of hcv infected patients harboring genotype 1a. after purification and cloning the pns3 into ta-cloning vector, the be...

In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...

Background: RNA interference (RNAi) is the mechanism of gene silencing-mediated messenger RNA degradation by small interference RNA (siRNA), which becomes a powerful tool for in vivo research, especially in the areas of cancer. In this research, the potential use of an expression vector as a specific siRNA producing tool for silencing of Bcr-abl in K562 cell line has been investigated. Methods:...
