Protection by iodide of lens from selenite-induced cataract

Background. Iodide has been used empirically against different age-related eye diseases, including cataract. The purpose of the present study was to investigate the effect of iodide on selenite-induced cataract in rat lens. Methods. Young white rats received subcutaneously sodium selenite (20 and 30 nmol/g b.w.) on day 13 post partum (p.p.). Cataract development was measured by expert estimation and image data analysis. Potassium iodide (1.5 nmol/g b.w.) was given (1-5 times) i.p. at different times with respect to the selenite administration. Lens opacification was analyzed in selenite, selenite-iodide, iodide and control groups on day 7 after selenite administration. Results. Iodide showed a significant protective effect against selenite cataract when injected 2 days (2 times) before selenite injection, i.e., on days 11 and 12 p.p. No significant effects on lens opacity were found: (1) after only one iodide injection (on day 12 p.p.), (2) after an initial iodide administration 1 h before selenite and (3) after injections of iodide once a day for 5 consecutive days. The protective effect of iodide was the same (about 50%) for both selenite doses used. Conclusions. There is a time-dependent protective influence of iodide against selenite cataract development. It is supposed that the anticataract effect of iodide could be based on direct or indirect antioxidant mechanisms.

Abiotic formation of methyl iodide on synthetic birnessite: A mechanistic study

Methyl iodide is a well-known volatile halogenated organic compound that contributes to the iodine content in the troposphere, potentially resulting in damage to the ozone layer. Most methyl iodide sources derive from biological activity in oceans and soils with very few abiotic mechanisms proposed in the literature. In this study we report that synthetic manganese oxide (birnessite delta-MnO2) can catalyze the formation of methyl iodide in the presence of natural organic matter (NOM) and iodide. Methyl iodide formation was only observed at acidic pH (4-5) where iodide is oxidized to iodine and NOM is adsorbed on delta-MnO2. The effect of delta-MnO2, iodide and NOM concentrations, nature of NOM and ionic strength was investigated. High concentrations of methyl iodide were formed in experiments conducted with the model compound pyruvate. The Lewis acid property of delta-MnO2 leads to a polarization of the iodine molecule, and catalyzes the reaction with natural organic matter. As manganese oxides are strong oxidants and are ubiquitous in the environment, this mechanism could significantly contribute to the global atmospheric input of iodine. (C) 2013 Elsevier B.V.

Study of the mechanism of the electrochemical deposition of silver from an aqueous silver iodide suspension

The present work examines the reduction of solid silver iodide on a silver electrode and proposes a mechanism for this process. Voltammetric and coulometric studies for the steady and transient states showed adsorption of silver iodide at the electrode depending on its concentration; this adsorption is in accordance with the Langmuir isotherm for low concentrations and with multi-layer models (such as the BET isotherm) for higher concentrations. Reduction of silver iodide at the silver electrode can take place through several processes such as direct reduction of solid particles, or reduction of the adsorbed silver iodide and involves the formation of a dendritic silver deposit not adhering to the electrode and free iodide in solution. Silver is then recovered easily by filtration of the initial suspension. (C) 2000 Elsevier Science B.V. All rights reserved.

The preparation of primary poly-hexafluoropropylene oxide halides (poly-HFPO-CF2X where X = I, Br, Cl and F)

Perfluorinated polyethers (PFPEs) are an important class of chemicals in industry due to their outstanding thermal stability, chemical inertness, and low vapor pressure. Since the first report on the polymerization of hexafluoropropylene oxide, there have been many papers on functionalized PFPEs. We have found that the reaction of poly-hexafluoropropylene oxide (HFPO) acid fluoride with LiI leads, to first the secondary and subsequently, to the primary poly-HFPO iodide. The primary poly-HFPO iodide, like perfluoroalkyl iodide, should provide the starting point for many new products. In this paper, from the primary poly-HFPO iodide we have prepared the family of primary poly-HFPO halides (X = I, Br, Cl and F). Their spectral data are discussed.

Cyclic AMP impairs the PRL stimulation of iodide uptake into mouse mammary tissues

In earlier studies the uptake of iodide into mammary cells was found to occur by a mechanism similar to that in thyroid cells (i.e., the uptake occurs via a sodium-iodide symporter that is inhibited by perchlorate and thiocyanate). Although cyclic AMP stimulates the iodide transport mechanism in thyroid cells, the present studies show that cyclic AMP, as well as pharmacological agents that elevate cyclic AMP, impair iodide uptake into mammary cells. In addition, elevated cyclic AMP levels interfere with the PRL stimulation of iodide uptake as well as iodide incorporation into proteins in mammary tissues. Clearly, cyclic AMP has opposite effects on regulating iodide uptake processes in mammary versus thyroid cells.

Carbon dots-based fluorescent probes for sensitive and selective detection of iodide

We report on a simple method for the determination of iodide in aqueous solution by exploiting the fluorescence enhancement that is observed if the complex formed between carbon dots and mercury ion is exposed to iodide. Fluorescent carbon dots (C-dots) were treated with Hg(II) ion which causes quenching of the emission of the C-dots. On addition of iodide, the Hg(II) ions are removed from the complex due to the strong interaction between Hg(II) and iodide. This causes the fluorescence to be restored and enables iodide to be determined in the 0.5 to 20 mu M concentration range and with a detection limit of similar to 430 nM. The test is highly selective for iodide (over common other anions) and was used for the determination of iodide in urine.
