in the present study, aqueous solutions of some copper-complexing ligands were screened for their cytotoxicity using brine shrimp lethality test. among the ligands tested, diacetyl-bis(n4-methylthiosemicarbazones) (atsm) proved to be the most safe and non-toxic compound (2% lethality at 10 ppm), while pyruvaldehyde bis(n4-methyl)thiosemicarbazone (ptsm) was shown to possess low toxicity (7% let...

We present a method for DNA extraction from peripheral blood using sugar, commercial detergent, and sodium salt. Our method is simple, fast, and inexpensive; its qualitative parameters do not significantly differ from the standard salting-out procedure.

The effect of dry salting during the cold-smoking process was evaluated on Atlantic salmon initially stored in refrigerated seawater (RSW) or ice. A 2D mathematical model developed from first principles, simulating heat and mass transfer at increasing duration. This validated using experimental values compared with empirical Zugarramurdi Lupín. predicted were used for water activity prediction ...

Introduction: Mineralogical studies have demonstrated that the nakhlite SNC meteorites have preserved the effects of water-rock interaction between a hydrothermal brine and the nakhlite parent rocks on Mars. Brittle fracturing and corrosion of olivine grains and mesostasis associated with the hydrothermal event have left veins of zoned Fe-carbonate, Fe-smectite (with minor serpentine), and an a...

the chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability. in this work, the effect of surfactants on oil/brine interfacial tension was experimentally investigated. first, the effect of surfactants concentration was surveyed. afterwards, the effect of salinity on surfactant be...

The aim of this study was to compare different DNA-extraction methods and selective enrichment broths for their effectiveness to detect Salmonella Typhimurium in artificially inoculated swine feces samples (100 CFU/ g) by polymerase chain reaction. After enrichment in Rappaport-Vassiliadis, selenite cystine or MüllerKauffmann tetrathionate, aliquots were used for DNA extraction by three differe...

The effects of cosolvents on the solubility and hydration of small nonpolar solutes in solution has been investigated using a combination of molecular dynamics simulation and Widom particle insertion calculations. Results were obtained for helium, neon, argon, and methane solutes in solutions of sodium chloride, ammonium sulfate, calcium chloride, ammonium acetate, tetramethylammonium chloride,...
