We investigated the in vitro superoxide anion scavenging activities of fluvastatin and its metabolites. Fluvastatin showed dose-dependent superoxide anion scavenging activity in the NADH/phenazine methosulphate (PMS)/nitroblue tetrazolium (NBT) system, and the effect was as potent as the reference antioxidant, trolox, which is a water-soluble alpha-tocopherol derivative. The superoxide anion sc...

The relationship between vascular generation of superoxide anion and spontaneous tone observed in the isolated aorta was studied in hypertensive rats infused with angiotensin II. Aortic rings from hypertensive, but not from sham-operated rats, demonstrated oscillatory spontaneous tone that represented 52+/-5.6% of the maximal contraction to KCl. Spontaneous tone was prevented by calcium-free bu...

In this work, the effect of an ammonium nitrate ionic liquid on corrosion susceptibility Al-Cu-Mg alloy was investigated. The anion and cation anodic cathodic kinetics were studied separately using potentiodynamic polarisation testing, electrochemical impedance spectroscopy scanning electron microscopy. results revealed a significant inhibition, associated with cation/anion synergy. however inc...

The serum anion gap has been utilized to identify errors in the measurement of electrolytes, to detect paraproteins, and, most relevant to the nephrologist, to evaluate patients with suspected acid-base disorders. In regard to the latter purpose, traditionally an increased anion gap is identified when it exceeds the upper limit of normal for a particular clinical laboratory measurement. However...

This work underscores the relationship between mechanical properties of anion exchange membranes and pH, which together can have a profound effect on power output fuel cells.

The role of lipophilic anionic and cationic additives on the potentiometric anion selectivities of polymer membrane electrodes prepared with various metalloporphyrins as anion selective ionophores is examined. The presence of lipophilic anionic sites (e.g. tetraphenylborate derivatives) is shown to enhance the non-Hofmeister anion selectivities of membranes doped with In(III) and Sn(IV) porphyr...

The current study was attributed to uranium (VI) ions adsorption using a anion exchanger resin, Dowex®2x8, in the presence of sulfate anions. Evaluation of operational parameters including contact time, pH, initial concentration of uranium ions, and presence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution was assessed on sorption performance of ...

We propose an organic field effect transistor (OFET)-based sensor design as a new and innovative platform for anion detection. OFETs could be fabricated on low-cost plastic film substrates using printing technologies, suggesting that OFETs can potentially be applied to practical supramolecular anion sensor devices in the near future.

Data are reported for T(m), the temperature midpoint of the thermal unfolding curve, of ribonuclease A, versus pH (range 2-9) and salt concentration (range 0-1 M) for two salts, Na(2)SO(4) and NaCl. The results show stabilization by sulfate via anion-specific binding in the concentration range 0-0.1 M and via the Hofmeister effect in the concentration range 0.1-1.0 M. The increase in T(m) cause...
