In a group of dogs in whom fulminant liver failure had been induced, perfusion of blood through activated charcoal resulted in a significantly longer survival than that of a similar group of dogs whose blood was not so treated. An otherwise progressive rise in blood ammonia concentration was halted in the treatment group. In another group of dogs with fulminant liver failure perfusion of blood ...

Amberlite XAD-4 was covalently linked with octa-O-methoxy resorcin[4]arene through N=Nto form chelating resin, which has been duly characterized and successfully used for separation and preconcentration of rareearth metal ions like U(VI), Th(IV), La(III) and Ce(III). Various physiochemical parameters like pH, flow rate, sorption capacity, breakthrough studies, distribution coefficient, preconce...

We describe a simple and selective method for analysing propranolol and a sensitive test for its control in urine. A flow-through fluorescence optosensor based on on-line immobilization in a non-ionic-exchanger (Amberlite XAD-7) solid support in a continuous flow was used in both cases. Determination was made in 5 mM H(2)PO(4)(-)/HPO(4)(2-) buffer solution at pH 6 at a working temperature of 20...

A method for the detection of T-2 metabolites was developed and applied to analysis of metabolites in excreta of broiler chickens administered 3H-labeled T-2 toxin. The method used acetonitrile extraction and partitioning with petroleum ether followed by chromatography on Amberlite XAD-2, Florisil, and Sep-Pak C18. The recovery of T-2 toxin added to the chicken excreta was 73% at a concentratio...

The adsorption characteristics of As(V) and As(III) on titanium dioxide loaded Amberlite XAD-7 resin have been studied. The resin was prepared by impregnation of Ti(OC2H5)4 followed by hydrolysis with ammonium hydroxide. Batch adsorption experiments were carried out as a function of the pH, shaking time and the concentration of As(V) and As(III) ions. The resin showed a strong adsorption for As...

Synthetic resin, Amberlite XAD-4 was linked covalently with the third generation supramolecule, octa-O-methoxy resorcin [4] arene through -N=Ngroup to form chelating resin, which has been characterized and effectively used for the separation and preconcentration of metal ions such as Ni(II), Cu(II), Zn(II) and Cd(II). Critical parameters such as pH, flow rate, sorption capacity, breakthrough st...

Common medlar (Mespilus germanica L.) is a long-lived plant with hard fruits, which are harvested in the fall and stored cold dark places. The aim of work was to obtain extract from freeze-dried fruits medlar. Then, samples were purified on column Amberlite XAD-16 ion exchange resin (two fractions obtained tested further steps: methanol (MF) water (WF)). A quantitative analysis polyphenolic com...

Abstract Punica granatum peel is a significant source of polyphenolic compounds that have potential uses as drugs. This study aimed to obtain and purify derived from pomegranate evaluate their anticancer activity in cell lines. Polyphenols the were extracted using hybrid ultrasound‐microwave technology. Different mass:volume ratios water:ethanol used during extraction. Purification was performe...

Combinatorial chemistry was used to extend the knowledge of beer thiols by synthesizing 13 mercapto primary alcohols and 6 other compounds (mercapto ketones and corresponding alcohols). Their respective mass spectra, retention indices on two columns, odor descriptors, and best estimated-gas chromatography-lowest amounts detected sniffing (BE-GC-LoADS) are reported. The descriptor "cheese", comm...
