Expression of the human sodium/iodide symporter (hNIS) in xenotransplanted human thyroid carcinoma

The uptake of iodide in thyroid epithelial cells is mediated by the sodium/iodide symporter (NIS). The uptake of iodide is of vital importance for thyroid physiology and is a prerequisite for radioiodine therapy in thyroid cancer. Loss of iodide uptake due to diminished expression of the human NIS (hNIS) is frequently observed in metastasized thyroid cancer. So far, no animal model for the study of radioiodine therapy in thyroid cancer has been available. Strategies to restore iodide uptake in thyroid cancer include the exploration of hNIS gene transfer into hNIS defective thyroid cancer. We have performed a stable transfection of hNIS into the hNIS defective follicular thyroid carcinoma cell line FTC133. Stabily transfected colonies exhibited high uptake of (NaI)-I-125, which could be blocked completely with sodiumperchlorate. hNIS transfected FTC133 and non-transfected cell lines injected subcutaneously in nude mice formed tumors after 6 weeks. Iodide uptake in the hNIS transfected tumor was much higher than in non-transfected tumor, but a rapid release of radioactivity from the hNIS transfected tumor was observed. Further studies are necessary to investigate the role of hNIS in relation to other thyroid specific proteins in iodide metabolism in thyroid cancer.

INHIBITION EFFECT OF POTASSIUM-IODIDE ON CORROSION OF STAINLESS-STEEL IN HYDROCHLORIC-ACID SOLUTION

The inhibition effect of potassium iodide on the corrosion of stainless steel has been examined using weight loss and electrochemical measurements. Potassium iodide was found to be an excellent inhibitor for stainless steel types 316, 430 and 440 (efficiency more than 95%), and moderate for type 304. The corrosion rates in 1 M HCl and in presence of potassium iodide fit an Arrhenius equation. The presence of potassium iodide lowered both the activation energy and the rate of reaction. Polarization measurements indicated that potassium iodide acts as an anodic inhibitor particularly at higher concentrations and as a cathodic inhibitor at lower concentrations. The synergistic effect of potassium iodide on the inhibitive efficiency of the organic substances was studied.

Sodium-iodide symporter (NIS)-mediated accumulation of [(211)AT]astatide in NIS-transfected human cancer cells

The cellular expression of the sodium iodide symporter (NIS) has been shown to confer iodide-concentrating capacity in non-thyroid cell types. We examined the role of NIS in the uptake of the alpha-particle emitting radiohalide [At-211]astatide in the UVW human glioma cell line transfected to express NIS. [At-211]Astatide uptake is shown to be NIS-dependent, with characteristics similar to [I-131]iodide uptake. These studies suggest [At-211]astatide as a possible alternative radionuclide to [I-131]iodide for NIS-based endoradiotherapy, and provide a model for the study of [At-211]astatide behavior at a cellular level.

Treatment of a series of alcohols with triphenylphosphine and cyanogen iodide (a positive halogen source) affords the corresponding alkyl iodides in good yields.

Two consecutive Eley-Rideal reaction steps in a D atom adsorbate interaction: from methylene iodide via methyl iodide to methane

The interaction of gaseous D atoms with methylene iodide molecules adsorbed on graphite monolayer covered Pt(lll) surfaces was studied using direct product rate measurement. At 85 K methane was observed as a reaction product from two consecutive D/adsorbate reaction steps. Via D addition to methylene iodide, adsorbed methyl iodide is formed as an intermediate. Subsequently, D abstracts methyl from methyl iodide towards methane. Approaching and passing the methyl iodide intermediate desorption temperature of 135 K during the reaction, the desorption of the intermediate prevents methane production. The kinetics of methane and intermediate methyl iodide formation is in agreement with the operation of Eley-Rideal reaction steps. This is in accordance with the expectation that on a substrate with a flat adsorption well for atoms from the gas phase the Eley Rideal mechanism should operate in atom/adsorbate reactions.

Biocompatible Choline Iodide Catalysts for Green Living Radical Polymerization of Functional Polymers

Herein, nontoxic and metabolizable choline iodide analogues, including choline iodide, acetylcholine iodide, and butyrylcholine iodide, were successfully utilized as novel catalysts for green living radical polymerization (LRP). Through the combination of several green solvents (ethyl lactate, ethanol, and water), this green LRP process yielded low-polydispersity hydrophobic, hydrophilic, zwitterionic, and water-soluble bio-compatible polymethacrylates and polyacrylates with high monomer conversions. Well-defined hydrophobic-hydrophilic and hydrophilic-hydrophilic block copolymers were also synthesized. The accessibility to a range of polymer designs is an attractive feature of this polymerization. The use of nontoxic choline iodide catalysts as well as green polymerization conditions can contribute to sustainable polymer chemistry.

DETERMINATION OF IODIDE- AND TOTAL-IODINE IN OSAKA BAY BY AN ELECTROLYTIC CONCENTRATION METHOD

Iodide- and total-iodine (Iodide + iodate) in seawaters of Osaka Bay were determined by an electrolytic concentration on glassy carbon electrode and detection with a polished Ag3SI electrode. The standard deviation of this method was within about 2%. The concentrations of iodide-iodine in seawaters of Osaka Bay were in the range from 0.10 to 0.30 pM and from 0.24 to 0.47 pM for total-iodine. Compared with those values in the open oceans, iodide was enriched in Osaka Bay, because of activities of marine organisms. While, totaliodine showed considerable uniform distribution.
