The application of sulfur nanoparticles as an efficient adsorbent for the solid-phase extraction and determination of the trace amounts of Pb and Pd ions was investigated in environmental samples using flame atomic absorption spectrometry. Effects of various parameters such as pH, flow rate of sample and eluent, type and concentration of eluent, sample volume, amount of adsorbent and interferin...

Fermentation characteristics of four strains of brewer's yeast (Saccharomyces cerevisiae strain 70424, S.rouxii strain 2535, S. rouxii strain 2531 and Saccharomyces ludwigii strain 3447) in Yeast Moldbrothcontaining four different fermentable sugars (glucose, fructose, maltose, or sucrose) were studied. Theaim was to consider the suitability of different strain/sugar treatment...

Using a conventional thermal chemical vapor deposition (CVD) system, ethanol vapor was enclosed in a reactor, i.e., no flow, with Co/Mo dip-coated quartz substrates to synthesize submillimeter long vertically aligned single-walled carbon nanotube (SWNT) films successfully. The no-flow CVD method yielded an increase in film thickness of up to 0.11 mm compared with the normal flowing gas method f...

Massively parallel sequencing has provided a more affordable and high-throughput method to study microbial communities, although it has mostly been used in an exploratory fashion. We combined pyrosequencing with a strict indicator species statistical analysis to test if bacteria specifically responded to ethanol injection that successfully promoted dissimilatory uranium(VI) reduction in the sub...

Cellular effects of ethanol in YD-15 tongue carcinoma cells were assessed by MTT assay, caspase activity assay, Western blotting and flow cytometry. Ethanol inhibited the growth and proliferation of YD-15 cells in a dose- and time-dependent manner in an MTT assay. The effects of ethanol on cell cycle control at low percent range of ethanol concentration (0 to 1.5%), the condition not inducing Y...

The present study evaluated the antimutagenic and anticancer activities of A. marina leaf extract. The antimutagenic activity of ethanol and water extracts of A. marina leaf (concentration 10 mg/plate for 48 h) was evaluated using the Salmonella typhimurium TA100 strain in the Ames test with (+S9) and without (−S9) metabolic activation, and its anticancer effect with concentrations of 200, 400,...

The cause of the urinary alcohol level (UAL) cycle in rats fed ethanol at a constant rate has been shown to involve the hypothalamic-pituitary thyroid axis. Because the effect of thyroid hormone on the metabolic rate is augmented by catecholamines, the role of catecholamines was investigated by using the intragastric ethanol feeding model of alcoholic liver disease in which the UAL cycles over ...

AIMS The principal aim of this study was to investigate the oxidative effects of chronic ethanol consumption on the functions of the heart and the kidney and the possible modification of this effect by folic acid supplementation. Moreover, in order to find whether this oxidative profile affects cardiovascular function, parameters such as heart rate and glomerular filtration rate were also asses...
