background: escherichia coli o157:h7 is a gram-negative and facultative anaerobic food-borne bacterial pathogen. the major purpose of this study was to evaluate physicochemical characteristics of nanoliposome garlic essential oil (eo) and its antibacterial effect on e. coli o157:h7. methods: nanoliposome garlic eo was prepared by ethanol injection method and its physicochemical properties were ...

regarding to prevalence of preterm labor and its consequences, there are different reports on relationship between bacterial vaginosis and preterm labor. this study was performed to evaluate the effect of metronidazole therapy on preterm labor in women with bacterial vaginosis. this randomized clinical trial was performed on 120 women suffering from bacterial vaginosis at 20-34 weeks of pregnan...

introduction: the purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and mta. methods: forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. the samples were divided randomly into three experimental (n=13) and two control groups (n=3). all teeth were instrume...

background: considering the high prevalence of bacterial vaginosis and its association with urinary tract infection in women and treatment of gynecologic problems occur when a high recurrence of bacterial vaginosis is often treated with antibiotics. the purpose of this study is to investigate the inhibitory effect of lactobacillus rhamnosus on pathogenic bacteria isolated from women with bacter...

the objective of this study was to determine the most common type of pathogen causing conjunctivitis. out of 495 patients who referred to the zahedan eye clinic from may 22, 199 1 to october 22, 1992,296 cases were diagnosed as nonbacterial conjunctivitis. from the remaining number of cases, two patients had chlamydia and six patients had candida albicans, while the frequency of bacterial infec...

Through the hydrolysis of casein, a cultural characteristic has been established in the preliminary identification of Serratia marcescens. Compared against 438 strains of the families, Pseudomonadaceae and Enterobacteriaceae, this organism has a reproducible capability to decompose casein, while most other Gram-negative bacilli failed to produce any hydrolysis, or, at the most, hazy zones only....

Multivariate Discriminant Analysis (MDA) has long been used to classify failing and non-failing firms with high accuracy rates, although a number of methodological flaws are well known. The alternative approach based on Conditional Probability Analysis (CPA) models have been applied to forecast mergers and acquisitions and extended to the prediction of corporate failure. This is used her to dis...

An effective neural network algorithm of the perceptron type is proposed. The algorithm allows us to identify strongly distorted input vector reliably. It is shown that its reliability and processing speed are orders of magnitude higher than that of full connected neural networks. The processing speed of our algorithm exceeds the one of the stack fast-access retrieval algorithm that is modified...

Methods CSCs were isolated using the sphere-forming assay in serum-free medium under non-adherent conditions and characterized for the expression of mesenchymal stem cell markers (CD90, CD105, CD73) by flow cytometry. The chemosensitity of MNNG and CSCs to doxorubicin (DOX), cisplatin (CIS) and methotrexate (MTX) was evaluated using the MTT colorimetric assay after an incubation period of 48h. ...
