The aim of this study was to assess the antibacterial activity of grape vinegar against F. psychrophilum.The antibacterial activity was determined by using agar well diffusion assays. The vinegar was tested against two strains of F.psychrophilum.While the highest inhibition zone diameter of grape vinegar was determined as 60 mm, the lowest was 47mm against to the pathogen. Grape vinegar display...
The purpose of this research aimed to determine the antibacterial effectiveness methanolic extract dragon scales leaves (Drymoglossum piloselloides) against MRSA (Methicilin-resistant Staphylococcus aureus) and Eschericia coli bacteria in vitro using diffusion method. This used a population Methicillin-resistant aureus bacteria. sample be is scale leaf methanol extract. method experimental with...
asafoetida is the dried latex exuded from the living underground rhizome or tap root of ferula assafoetida. antibacterial characteristic of asafoetida was shown using the circular zone diameter of bacterial growth inhibition by disk-diffusion method on two gram positive and three gram negative bacteria. then, the bacterial genomic dna damage, induced by f. assafoetida latex, was demonstrated us...
Background and Purpose: Herbal toothpastes are more secure and efficacious and less poisonous due to containing natural chemicals as compared with the synthetic toothpastes. The present study aimed to formulate a polyherbal toothpaste using accessible medicinal plants in Iran and evaluate its efficiency in the protection of oral hygiene and prevention of dental caries. Materials and Methods:...
Paper discs containing 5 microng of novobiocin were used as a presumptive test to differentiate peptococci and peptostreptococci. Zone diameters were measured and minimum inhibitory concentrations (MIC) of the antibiotic for each group were performed to ascertain the activity of the antibiotic against these genera. All strains of peptococci showed no zone of inhibition in the disc test together...
cohesion is an indispensable linguistic feature in discourse analysis. lexicald such a differe cohesion and conjunction in particular as two crucial elements to textual cohesion and comprehension has been the focus of a wide range of studies up to now. yet the relationship between the open register and cohesive devices has not been thoroughly investigated in discourse studies. this study concen...
objective bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. in this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. materials and methods we ...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
