Background and Objectives: Urinary tract infections (UTI) are one of the most common infectious diseases with different microbial agent and antimicrobial resistant pattern in hospitalized patients and outpatients. In order to assess the adequacy of therapy, knowledge of prevalence and resistance pattern of the bacteria is necessary. The main aim of this study was to evaluate the prevalence and ...

based studies are conducted, the effects of Al are usually confounded with other factors such as levels of P, Ca, Despite good resistance to acid-soil stresses, white clover (TriMo, Mn, Zn, organic acids, and other soil components folium repens L.) is not found on some acid soils. Our objectives (Edmeades et al., 1995; Villagarcia et al., 2001). An exwere to develop a large-leafed white clover ...

Effects of Daphnia magna enriched with cod liver oil (CLO) as a source of highly unsaturated fatty acid (HUFA) on growth, survival, stress resistance, and fatty acid composition of the Persian sturgeon larvae were evaluated. Daphnia enriched for three different time periods (3, 6, and 9 hours) and non-enriched Daphnia were fed to the Persian sturgeon larvae (average weight 61.6±0.4mg) during 14...

BACKGROUND The TolC outer membrane channel is a key component of several multidrug resistance (MDR) efflux pumps driven by H(+) transport in Escherichia coli. While tolC expression is under the regulation of the EvgA-Gad acid resistance regulon, the role of TolC in growth at low pH and extreme-acid survival is unknown. METHODS AND PRINCIPAL FINDINGS TolC was required for extreme-acid survival...

Resistance to insulin-mediated glucose uptake is well documented in uremia. We have previously reported that in vivo resistance to insulin mediated amino acid uptake is present in the skeletal muscle of acutely uremic rats. This report compares the effect of insulin on in vitro 14C alpha-amino isobutyric acid and cycloleucine uptake by skeletal muscle from uremic and control rats. Intracellular...

Background and purpose: Due to the emergence of antibiotic resistance bacteria, treatment of urinary tract infection is becoming more problematic. Integrons are mobile genetic elements that play an important role in dissemination and accumulation of resistance genes of multidrug resistance in bacteria. The aim of the present study was to determine the antibiotic resistant profile, frequency of ...
