OBJECTIVES Escherichia coli is the leading bacterial species implicated in intra-abdominal infections. In these infections a high bacterial burden with pre-existing resistant mutants are likely to be encountered and resistance could be amplified with suboptimal dosing. Our objective was to investigate the pharmacodynamics of moxifloxacin against a high inoculum of E. coli using an in vitro holl...

Chlorpyrifos (CP) is one of the most widely used organophosphate pesticides in agriculture worldwide, but its extensive use has led to the contamination of various soil and water systems. Microbial bioremediation is considered to be one of the most viable options for the removal of CP from the environment; however, little is known about the soil bacterial diversity that degrade CP. Sequential s...

Zinc oxide nanoparticles (ZnO NPs) are used widely in consumer and industrial products, however, their influence on gut microbiota and metabolism and their mutual interactions are not fully understood. In this study, the effects of ZnO NPs on ileal bacterial communities, plasma metabolites, and correlations between them were investigated. Hens were fed with different concentrations of ZnO NPs [...

There have been many published studies aiming to identify temporal changes in river flow time series, most of which use monotonic trend tests such as the Mann–Kendall test. Although robust to both the distribution of the data and incomplete records, these tests have important limitations and provide no information as to whether a change in variability mirrors a change in magnitude. This study d...

Helicobacter pylori is the causative agent of gastritis and peptic ulcer disease. Eradication of H. pylori is hard to achieve and often require multiple antibiotics regimens. These regimens are quite expensive and have substantial side effects. Licorice is a traditional drug which is frequently used for gastric discomforts in Iran. The susceptibility of H. pylori to the extract of licorice has ...

Background & Aim: The aim of this study was to investigate the antimicrobial effects of Zataria multiflora against some Acinetobacter baumannii strains isolated from clinical samples. Experimental: Twelve strains of Acinetobacter baumannii were isolated from referred patients in Zabol hospital. Essential oil of Zataria multiflora...

background: there is evidence of antibacterial properties of human chorioamniotic layer. however, the distinctive contribution of its individual parts, amniotic and chorionic membranes, to these effects is still unknown. the aim of present study was comparison of the antibacterial effects between amniotic and chorionic membranes. methods: chorioamniotic layer was removed from placenta belonging...

in the present study we focused on the electronic and structural properties of na and mg adsorption on the surface of the (6, 6) armchair sicnts. the adsorption energy (eads), band gap energy (eg), partial density of state (pdos), chemical potential (μ), global hardness (η), electrophilicity index (ω), global softness (s), work function values (φ) and work function change (δφ) are calculated by...

introduction conventional water treatment consist of unit processes include coagulation, flocculation, clarification, filtration and disinfection that goal is removal of turbidity, color and certain bacterial species. in filtration process flocculated substances that have not removed in pervious stage are sediment. filter media is often silica sand that removal mechanism is complex and consists...
