Background: Many plant growth-promoting bacteria including Rhizobia contain the 1-aminocyclopropane-1-carboxylate (ACC) deaminase enzyme that can leave ACC, and thereby lower the level of ethylene in stressed plants. Drought and salinity are the most common environmental stress factors for plants in Iran. Objectives: The main aim of this research was development of bio-fertilizers containing A...

background and objectives : the rapid emergence and dissemination of carbapenemase-producing klebsiella pneumoniae strains and other members of the enterobacteriaceae poses a considerable threat to the care of hospitalized patients and to public health. the aim of this study was to determine the frequency of metallo-β-lactamases (mbl) and vim-1 gene in multidrug-resistant strains of k. pneumoni...

background: pseudomonas aeruginosa is the causing agent of many hospital infections and metallo-beta-lactamases (mbl) are being reported with increasing frequency. the aim of this study was to determine the frequency of metallo-&beta-lactamases; (mbl) and vim-1 gene in multidrug-resistant strains of p. aeruginosa isolates and to compare the methods of phenotypic and molecular detection. materia...

objective: toxoplasmosis can lead to severe pathological effects in both infected humans and animals. the various dna vaccines against toxoplasma compose of single or cocktail antigens have been investigated but they have partial protective against disease. in this study, we used pcrop1 as a dna vaccine and aluminium phosphate and aluminium hydroxide to compare their efficacy as mineral adjuvan...

Background: Due to the lack of information about the role of 4G/5G polymorphism of PAI-1 Gene in susceptibility to thyroid tumors, this study was performed to evaluate the potential effects of this polymorphism on clinicopathologic features of thyroid tumors in Iranian Azeri Turkish patients. Methods:In this case-control study, 90 patients with thyroid tumors ...

during 2004-2007, a field survey was conducted in different vineyards to determine the fungal pathogens associated with grapevine decline in different provinces of iran including fars,hamedan,isfahan, and kohgiluyeh and boirahmad. twenty-seven isolates of botryosphaeriaceae were recovered from vines showing decline and dieback symptoms only in fars province. based on morphological and cultural ...

cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...
