to determine tetraploid pollinators resistant to cercospora leaf spot disease and bolting with optimum yield and quality, five tetraploid pollinators were crossed with a male sterile line, sb17. the hybrid seed was harvested from the male-sterile line. the hybrids together with four controls including resistant and susceptible cultivars (a total of 9 cultivars), were evaluated in a randomized c...

aim: the aims of this study were to characterize iranian shigella sonnei strains isolated from pediatric cases and evaluate the utility of multilocus variable-number tandem-repeat (vntr) analysis (mlva) for genotyping of local s. sonnei strains. background: s. sonnei has become the dominant species in certain parts of iran. although pfge is still a gold standard for genotyping and source tracki...

densities and excess molar volume of the binary and ternary mixtures formed by nbutylacetate+ 1-butanol + 1,2-butanediol were measured at (298.15, 303.15, and 308.15) k forthe liquid region and at ambient pressure (81.5) k pa , for the whole composition range. theexcess molar volumes,vme and excess partial molar volume vie ,were calculated fromexperimental densities.the excess molar volumes are...

background and objectives : pseudomonas aeruginosa is one of the most important gram negative opportunistic bacteria which causes infection among burn patients. resistance to the antibiotics in this group of bacteria is increased due to the activity of extended spectrum β-lactamase (esbls) genes. in the current study, we investigated the prevalence of two genes (blaper-1 & blaoxa10) related β-l...

background klebsiella pneumoniae is a family member of enterobacteriaceae. isolates of k. pneumoniae produce enzymes that cause decomposition of third generation cephalosporins. these enzymes are known as extended-spectrum beta-lactamase (esbl). resistance of k. pneumoniae to beta-lactamase antibiotics is commonly mediated by beta-lactamase genes. objectives the aim of this study was to identif...

background: the pathogenesis of gestational trophoblastic disease (gtd) is not clearly known. objective: in this study, immunoexpression of proteins bcl-2 and beclin-1 in trophoblastic lesions and normal trophoblastic tissue was conducted to study the mechanism of apoptotic and autophagic cell death that is expected to complete the study of gtd pathogenesis. materials and methods: bcl-2 and bec...

abstract   background: multiple sclerosis (ms) is the most common autoimmune disease of central nervous system with destruction of myelin sheath mediated by auto reactive cd4+ t lymphocytes. because of the possible role of epstein-barr virus in etiology of ms and t cells immune response, the aim of this study was to evaluate anti-epstein barr virus antibodies as a marker of reactivity and produ...
