Molecular and Functional Analyses of Transport Proteins for Organic Anions
… I performed comparative experiments with model organic anions in isolated proximal kidney tubules of killfish and CP of rat and spiny dogfish shark. ·First, I studied transport of the fluorescent cAMP analog fluo-cAMP. Inhibition studies indicate transport mediated by the export proteins Mrp2 …

Rapid analysis of inorganic and organic anions in kraft pulping liquors by capillary zone electrophoresis
… and/or speciating several important inorganic sulphur species, including: thiosulphate, sulphate, sulphite, sulphide and polysulphide in kraft pulping liquors and effluents by capillary zone electrophoresis. In addition, several other key anions, including: hydroxide, carbonate, …

The investigation of the effect of free organic anions on scale inhibitors used to prevent nucleation occurring in oil rig wells, using dynamic test equipment.
… field is very acidic. It is believed that these anions associate themselves with the scale inhibitors and so reduce the efficiency of the scale inhibitor. The identity and amount of the acids affecting the scale inhibitor needs to be found. This was preformed with extraction with a basic …

Radioimmunoassay and characterization of ligandin in the rat
… distinctive property of binding a wide range of organic anions, is a relative newcomer to the field of hepatic physiology and biochemistry, and its importance in relation to various aspects of hepatic and renal function has been given considerable stress (1-13).

High-performance liquid chromatographic methods for quantitative assessment of degradation products and extractives in pretreated lignocellulose.
… for simultaneous separation and quantitation of organic acids and neutral degradation products present in the corn stover hydrolysate. On the other hand, inorganic ions and some organic anions which present in water extractive from corn stover are separated and quantitated by the developed ion …

Intercalation d'anions organiques dans des composés lamellaires de type hydrotalcite.
… intercalation products have been prepared. Organic molecules were incorporated by different methods. The first method consisted of the direct intercalation of organic species during the metal hydroxide precipitation process. The second method was based on an ionic exchange process between …

Functional and Molecular Aspects of Xenobiotic Transport in Choroid Plexus
… that the CP is actively involved in removing organic anions and other organic compounds from the extra-cellular fluid (Pappenheimer et al., 1961; Villalobos et al., 2002; Miller et al., 2002; Breen et al., 2004; Baehr et al., in press). However, studying CP is difficult, due to complex …

Characterization of a human renal organic anion transporter
The renal excretion of organic anions, including a variety of endogenous substances, xenobiotics and their metabolites, involves an organic anion transport system with multiple specificity. The well characterized basolateral uptake step of this process involves the organic anion transporter 1 …

Oligomeric surfactants as novel type of amphiphiles : structure - property relationships and behaviour with additives
… effects were observed by adding special organic salts (e.g. sodium salicylate, sodium vinyl benzoate, etc.) to the surfactant dimers in stoichiometric amounts. For such mixtures, the critical aggregation concentration is strongly shifted to lower concentration, the effect being more …

Innovative, Platy Nano-Additives as Efficient Flame Retardants for Polymer Nanocomposites
The objective of this work was to explore inorganic layered materials (nano-additives) as innovative flame retardants for polymer nanocomposites. In particular, polystyrene (PS) nanocomposites were prepared with a variety of nano-additives including layered double hydroxides (LDHs), hectorite …

Effects of Acid Deposition and Changing Climate on the Hydrochemistry and Critical Loads of Watersheds in the Adirondack Region of New York
… exchangeable base cations, net mineralization of organic sulfur and nitrogen and release of previously retained SO42- and NO3-, and increases in concentrations of naturally occurring organic acids from soil. The future recovery of stream chemistry from acidic deposition may be altered by projected …
