This paper deals with the electrochemical properties of three iso-structural compounds general formula [SiW 10 O 36 (M 2 E )] 6- = Mo or W; S O). A first part is focused on their behaviors in aqueous medium. second concerns electrocatalytic these medium and preparation modified glassy carbon electrodes through a layer-by-layer methodology. method allowed preparing multilayer system, which was a...

Pectin cerium(IV) iodate (PcCeI) and (CeI) cation ion exchange materials were synthesized via sol–gel methods. The characterized by using Fourier transform infrared spectroscopy, X-ray diffractometer, thermogravimetric analysis, scanning electron microscopy. capacity (IEC), thermal stability, distribution coefficient (Kd), pH titrations investigated to recognize the behavior of materials. IEC p...

THE EI,ECTROKETI~‘~'~GRAM (ERG) was first recorded by Holmgren in 1865 (ZO), and it has proved to be a useful tool for studying retinal function for almost a century. Despite extensive studies, however, the cellular origins of the ERG components proximal to the receptors remain to be established. Quite recently it has become possible to record intracellularly from the retinal cells with fine mi...

Iodine is an elemental nutrient that is essential for mammals. Here we provide evidence for an acute therapeutic role for iodine in ischemia reperfusion injury. Infusion of the reduced form, iodide, but not the oxidized form iodate, reduces heart damage by as much as 75% when delivered intravenously following temporary loss of blood flow but prior to reperfusion of the heart in a mouse model of...

Published methods for radioiodination of rose bengal require reaction times of 1 hr or more at temperature from 50 to 120 degrees C. Through the use of an acidified ethanol solvent and potassium iodate oxidant, purified rose bengal is radioiodinated at room temperature within 15 min with chemical yields ranging between 93 and 97%. Radiochemical impurities are sufficiently minimized to permit pr...
