The Salmonella lactam test is a newly developed method for detecting genotoxins. This technique is based on the ability of DNA damaging agents to reverse expression of the beta-lactamase gene, an important gene that enables microbes to resist beta-lactam antibiotics. A construct p-SELECT Control DNA plasmid containing a beta-lactamase gene site was constructed in many mutant forms, including po...
The Survey of Consumer Expectations (SCE) infers respondents’ inflation expectations from density forecasts. Using numeracy data and tests for coherence among 117,000 respondents to the SCE, I find that forecasts suffer non-negligible reporting bias selective nonresponse. A simple verbal question collected by SCE suffers neither these deficiencies so has better properties deliver an accurate sn...

Abstract Background and objectives :Epidemic dysentery, which can be caused by different organisms, is a major problem in developing countries. The cause variability and drug resistance make the treatment difficult. This study was carried out to determine the prevalence and antimicrobial susceptibility patterns of Shigella in Isfahan reference laboratory. Materials and Methods: In this descript...
OBJECTIVES Ginseng Rh2+ is enzyme-treated ginseng extract containing high amounts of converted ginsenosides, such as compound k, Rh2, Rg3, which have potent anticancer activity. We conducted general and genetic toxicity tests to evaluate the safety of ginseng Rh2+. METHODS An acute oral toxicity test was performed at a high-level dose of 4,000 mg/kg/day in Sprague-Dawley (SD) rats. A 14-day r...
The aim with the present study was to examine the relationship between the subcomponents in working memory (WM) and mathematical performance, as measured by the National tests in a sample of 597 Swedish third-grade pupils. In line with compelling evidence of other studies, individual differences in WM capacity significantly predicted mathematical performance. Dividing the sample into four group...
Several investigators have claimed over the past decade that working memory (WM) and general intelligence (g) are identical, or nearly identical, constructs, from an individual-differences perspective. Although memory measures are commonly included in intelligence tests, and memory abilities are included in theories of intelligence, the identity between WM and intelligence has not been evaluate...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
AIMS To investigate whether current occupational exposure of coke oven workers to polycyclic aromatic hydrocarbons (PAHs) results in genotoxic effects measured in peripheral blood lymphocytes and whether these biomarkers are associated with the biomarkers of exposure. METHODS Blood and urine samples were collected immediately after a shift at the end of a working week from 50 coke oven worker...
