BACKGROUND Viruses have been identified as one of a variety of potential agents that are implicated in atherogenesis. METHODS AND RESULTS C57BL/6J mice were killed before or 2, 3, 5, 7, or 9 days after intranasal infection with 10(5) plaque-forming units (pfu) of Influenza A strain WSN/33. Peak infectivity in lungs was reached by 72 hours, and it returned to baseline by 9 days. No viremia was...
To determine whether aerosolization could impair bacterial survival, Pseudomonas syringae and Erwinia herbicola were aerosolized in a greenhouse, the aerosol was sampled at various distances from the site of release by using all-glass impingers, and bacterial survival was followed in the impingers for 6 h. Bacterial survival subsequent to aerosolization of P. syringae and E. herbicola was not i...
The gene pem, encoding the pectin methylesterase (PME) of Erwinia chrysanthemi 3937, was cloned and mutagenized by mini-Mu transposable elements. A second gene, pecY, which could act as a negative regulator of PME was found 5' to the pem gene. A PME-E. chrysanthemi derivative inoculate onto Saintpaulia plants was shown to be clearly noninvasive, demonstrating the important role of this enzyme i...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
BACKGROUND Erwinia asparaginase is antigenically distinct from E.coli-derived asparaginase and may be used after E.coli-derived asparaginase hypersensitivity. In a single-arm, multicenter study, we evaluated nadir serum asparaginase activity (NSAA) and toxicity with intravenously administered asparaginase Erwinia chrysanthemi (IV-Erwinia) in children and adolescents with acute lymphoblastic leu...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
The TPS1 gene from Candida albicans, which encodes trehalose-6-phosphate synthase, has been cloned by functional complementation of a tps1 mutant from Saccharomyces cerevisiae. In contrast with the wild-type strain, the double tps1/tps1 disruptant did not accumulate trehalose at stationary phase or after heat shock. Growth of the tps1/tps1 disruptant at 30 degreesC was indistinguishable from th...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...
the present study attempts to discover ideological differences between alcott’s novel (1868) named “little women” and its two persian translations. the first has been translated by morvarid and the second has been translated by obeidi. to this end, farahzad’s cda approach (2012) was used to analyze the ideology reflected in both translations by the two different translators. according to farahz...
