the aim of current study was to investigate the nucleotide sequence of seven trna genes in mitochondrial gene of khorasan’s native chicken and identification of possible mutations in it. for performing it, this part of the gene was cloned using the specific amplification initiators and cloned in the plasmid ptg19-t vector in dh5α strain of e-coli after the sampling and extracting the dna from w...

Background and Aims: DNA constructs containing HCV antigens have become one of the vaccine candidates for induction of anti-HCV cellular and humoral immunity. In this study, we constructed a novel expressing vector harboring a fusion sequence derived from an overlapping fragment in the middle of NS3 and a truncated core fragment to avoid troubles reported to be associated with full gene express...

The Upper Cretaceous strata were studied in a composite stratigraphic section named here Padeha-Baghak section in east of Koppeh-Dagh basin, north east of Iran. In this study, palynostratigraphy, palynofacies and depositional environment history of Abderaz Formation were integrated with sequence stratigraphy. Determination of sea level history and sequence units of the Abderaz Formation using s...

Convergence is an issue being widely concerned about. Thus, in this paper, we mainly put forward two types of concepts of convergence in mean and convergence in distribution for the sequence of uncertain random variables. Then some of theorems are proved to show the relations among the three convergence concepts that are convergence in mean, convergence in measure and convergence in distributio...

the asmari formation in tang-e surkh section is composed of 294 meters of thin to medium bedded and thick to massive bedded limestone associated with marly limestone. the studied section is located in the northwest of interior fars. based on deepening and shallowing patterns of microfacies, one hst and one third-order depositional sequence during rupelian and two third-order depositional sequen...

genetic typing methods of t. gondii strains have been extensively perfected in recent years. from a technical point of view, many tools usable for genetic studied on single-copy loci have been used: rflp, pcr-rflp, sequencing, rapd-pcr and isoenzyme analysis. we described the cloning and sequence analysis of the gene which encodes the major surface antigen (sag1 or p30) of t. gondii. sag1 is th...
