The interaction of the bipyridylium herbicides diquat and paraquat with the proteins gliadin and human serum albumin (HSA) as well as with cellulose and the effect of various ions on the strength of interaction were studied by charge-transfer chromatography. Both compound showed very similar behaviour. The ions decreased in each case the strength of interaction, the effect depended nonlinearly ...

in this research, the interaction of hexadecyl trimahyl ammonium bromide (htab) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. the obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as wyman binding pote...

A first-principles molecular dynamics (MD) scheme is presented on the basis of the density-functional (DF) theory with use of the the quantal hyper-netted chain (QHNC) approximation. The DF theory brings about exact expressions for the ion-electron and ion-ion radial distribution functions (RDF’s) of an electron-ion mixture as a model of a simple liquid metal. These exact expressions prove that...

First published August 22, 2006; doi:10.1152/ajprenal.00195.2006.—The interaction of ion channels with the actin-based cytoskeleton in epithelial cells not only maintains the polarized expression of ion channels within specific ...

A nanocomposite membrane Cu2+ ion-selective electrode has been constructed using a new compound ethyl 1,2,3,4-tetrahydro-4-(4-methoxyphenyl)-6-methyl-2-oxopyrimidine-5-carboxylat (ETMOC) as a neutral ionophore. The electrode works properly. It responds to Cu2+ ion with a sensitivity of 29.5 ± 0.2 mV/decade over the range 1.0 × 10−9 to 5.0 × 10−1M at p...

      Euphrates poplar (Populus euphratica Oliv.) is a woody species that is naturally distributed in the desert areas of some parts of Asia and Africa. Because of its outstanding features, it is a model plant to study environmental stress tolerance. This research was conducted from 2014 to 2016 in order to study the relationship between performance indices and ion concentrations. The cuttings ...

Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily increasing effort. Motivations can be found in the applicative potential and in the perspective to investigate novel regimesasavailable laser intensitieswill be increasing.Experimentshavedemonstrated, over awide range of laser and target parameters, the generation of multi-MeV proton and ion beams with...

Phenols began to play a prominent role very early in modern operative medicine in the 1860s when Lister introduced his ‘antisepsis’ approach. The treatment of open wounds by carbolic acid dramatically reduced morbidity and mortality of surgical patients for the first time [1]. This central place in operative medicine was lost when, in the early 20th Century, ‘asepsis’ replaced ‘antisepsis’. The...
