In recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. The core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

Here we describe a quantitative PCR-based approach to estimating the relative abundances of major taxonomic groups of bacteria and fungi in soil. Primers were thoroughly tested for specificity, and the method was applied to three distinct soils. The technique provides a rapid and robust index of microbial community structure.

conclusions it is suggested that determination of the target genotype by plasma subtyping for choosing the proper antiviral therapy is essential but may result in therapy failure. hcv genotyping in pbmc samples, along with plasma specimens, might be more beneficial. therefore determining the hcv genotype in pbmcs, before beginning the therapy is useful due to the possibility of occult infection...

conclusions: nested pcr as a sensitive chlamydia trachomatis detection test and endocervical specimens has been offered to detect this bacterium in spontaneous abortion. besides, c. trachomatis screening among pregnant women can be suggested to prevent abortion. results: the number of intercourses per week and history of miscarriage can be known as the risk factors of abortion. frequency of c. ...

background and aims: helicobacter pylori is the primary cause of various diseases. this study was conducted to determine the existence of h. pylori in springs and surface water in chaharmahal and bakhtiari province. methods: in this study, 29 water samples were collected from three different locations of zayanderud river, 24 springs, and two subterranean from june 2014 to august 2014 in chaharm...

conclusions there was a significant correlation between crs and presence of h. pylori in sinonasal mucosa. this relationship may reflect the role of h. pylori as one of the pathogenic factors in the development of crs. however, further studies are required to confirm this role. results nine patients (18%) with crs had h. pylori isolated from their samples whereas in the control group, h. pylori...
