BACKGROUND AND AIM: Helicobacter pylori (H. pylori) infection is one of the most common infections which still affects individuals worldwide. The main route for transmission of H. pylori infection is the oral route and this microorganism has been detected in dental plaque. In past decades, there have been a number of controversies about the station of dental pl...

background: consistency, backing process and content differences could influence cariogenic potential of foods. the aim was to compare plaque ph changes following consumption of two types of bread with different physical characteristics. methods: in this clinical trial, interproximal plaque ph of 10 volunteers with high risk of dental caries (saliva streptococcus mutans > 10 5 , high dental car...

Periodontal disease is an inflammatory disorder that triggered by bacterial plaque and causes the destruction of tooth-supporting tissues leading to tooth loss. Several bacteria species, including Porphyromonas gingivalis Aggregatibacter actinomycetemcomitans, are considered be associated with severe periodontal conditions. In this study, we demonstrated a quartz crystal microbalance (QCM) immu...

The quinolones inhibit the essential bacterial enzymes DNA gyrase and topoisomerase IV, which alter DNA topology after inserting a double-stranded break. DNA gyrase exists as an A2B2 tetramer, encoded by the gyrA and gyrB genes, and catalyses negative DNA supercoiling. Topoisomerase IV exists as a C2E2 tetramer encoded by the parC and parE genes, and is involved in chromosome partitioning. Prev...

In this paper we try to combine experiences gained in the Machine Translation project with research concerning the default extension of the terminological representation system BACK. We analyze various types of ambiguities that are problematic for translation and show that disambiguation is possible on the basis of default assumptions. Some of these defaults form preference rule systems, while ...
