background: emergence klebsiella pneumoniae resistant to quinolone antibiotics due to mutations in gyra and parc genes created problem for treatment of patients in different hospitals in iran. the objective of this study was to determine the amino acid substitutions of gyra and parc proteins in certain clonal lineages of the k. pneumoniae conferring high level quinolone resistance. methods: one...
objective(s) the aim of this study was to characterize the hepatitis b virus surface protein genotypes and sequence variations among hepatitis b virus surface antigen (hbsag) positive chronic patients in hormozgan province, south of iran. materials and methods a total of 8 patients enrolled in this study. the surface gene was amplified and directly sequenced. genotypes and nucleotide/amino acid...
Background and Aims: The aim of this study was to determine the correlation between the hepatitis B virus surface Ag (HBsAg) genotypes and variations in the clinical/serological pictures among HBsAg positive chronic patients from South Khorasan province of Iran. Methods: Twenty-five patients were enrolled in this study. The HBs Ag gene was amplified and was directly sequenced. Genotypes and nuc...
The aim of the present study was todeterminecharacteristics of Rheb gene and protein in Raini Cashmere goat. Comparative analyses of the nucleotide sequences were performed. Open reading frames (ORFs), theoretical molecular weights of deduced polypeptides, the protein isoelectric point, protein characteristics and three-dimensional structures was predicted using online standard softwares. The f...
The repeated amino-acid sequences in Citrobacter Freundii beta-lactamase may be indispensable for its function, because such repetitions cannot be simply attributed to a chance. In order to fully explore the functional units in Citrobacter Freundii beta-lactamase, it may need to analyse all the amino acid pairs, triplets, etc. along Citrobacter Freundii beta-lactamase from one terminal to the o...

Background: The SRY gene (SRY) provides instructions for making a transcription factor called the sex-determining region Y protein. The sex-determining region Y protein causes a fetus to develop as a male. In this study, SRY of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...
