Formation of CH3I in a NaI and methyl alkyl ketone solution under gamma irradiation conditions

We investigated the effects of concentrations of NaI and methyl alkyl ketone on the formation of methyl iodide under gamma irradiation conditions. Without irradiation, the formation of methyl iodide does not occur. For the formation of methyl iodide, the solution pH should be brought to lower than 6 by radiolytic decomposition of ketones and air. At a pH below 6, the iodide was oxidized into iodine, allowing for the formation of CH3I from the reaction of iodine and the CH3 radical. When the concentrations of NaI and methyl alkyl ketone were similar, the concentration of methyl iodide was generally at its highest, and as the gamma dose increased, the concentration of methyl iodide increased.

Urinary iodide excrecion and others thyroid function and thyroid autoimmunity parameters during pregnancy

The urinary iodide excretion of pregnant women of Buenos Aires was investigated using a potenciometric method. Furthermore; serum TSH, free T4 and anti-thyroid antibodies were analyzed to correlate iodide intake with the thyroid function and autoimmunity fenomena. We observed a high average urinary iodide level (740 mu g/24 h) similar to American and Japanese populations. The hormones levels and autoimmunity parameters agree with the consulted publications. We conclude there is no iodide deficiency in the tested patients and we discuss the effect that a high iodide intake might have on thyroid function and the development of autoimmune thyroid pathologies during pregnancy.

SPECTROPHOTOMETRIC MICRODETERMINATION OF EXCESS OF IODINE IN MERCURY(II) IODIDE-CRYSTALS

The excess of iodine in mercury(II) iodide crystals was determined by spectrophotometry. Dynamic dissolution of mercury(II) iodide samples in carbon tetrachloride allows the detection of minute amounts (< 1-mu-mol mol-1) of free iodine in the crystal. This method has a detection limit that is at least two orders of magnitude lower than for other methods for the determination of excess iodine. Many crystals grown under various iodine overpressure conditions were studied. The solubility limit of free iodine in mercury(II) iodide was found to be about 130-mu-mol mol-1 in the range 95-120-degrees-C. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Di(ethylxanthate) complex of cobalt(II) as neutral carrier for highly selective iodide electrode

A new solvent polymeric membrane electrode based on di(ethylxanthate) complex of Co(II) is described which demonstrates excellent selectivity toward the iodide ion.The resulting electrode exhibits fairly low detection limits and good selectivity properties.The selectivity sequence observed is iodide > thiocyanate > nitrite > bromide>perchlorate>sulfate>nitrate>chloride. The excellent selectivity for iodide is related to the unique interaction between the central Co(II) ion and iodide. The response mechanism of the electrode was also studied with the ac impedance and spectroscopic techniques.

Characterization of Thr-354 in the human sodium/iodide symporter (NIS) by site-directed mutagenesis

Sodium/iodide symporter (NIS) is the key molecule concentrating iodide in the thyroid gland. The first-described human NIS ON IS) mutation to cause a complete iodide transport defect was the T354P mutation. The Thr-354 lies in the midst of the putative ninth transmembrane segment which is well-conserved within the members of the SLC5A transporter family. Here we have investigated the molecular function of Thr-354 using site-directed mutagenesis and found that T354S and T354A mutations result in significantly decreased iodide transport activity, 50 % and 2 % of wild-type hNIS. Our findings indicate that whereas Thr-354 is indispensable for the complete NIS activity, the beta-hydroxyl group accounts for half, and the a-helical structure alone contributes for one-fiftieth of wild-type hNIS activity.

RECTAL ADMINISTRATION OF IODIDE AND PROPYLTHIOURACIL IN THE TREATMENT OF THYROID STORM

We administered potassium iodide and propylthiouracil per rectum, in conjunction with intravenous dexamethasone and propranolol, for emergent treatment of a patient in thyroid storm with small bowel obstruction, Shortly after initiation of this treatment, the patient successfully underwent two emergent surgical procedures for resection of an intestinal volvulus with advanced peritonitis, Serum levels of iodide and propylthiouracil showed substantial absorption of these drugs via the rectal route, Measurement of 24-h urinary-free iodide indicated that the bioavailability of potassium iodide delivered by retention enema was at least 40%, Parenteral iodide preparations have been unavailable in the past, and continue to be difficult to obtain emergently. Rectal administration of inorganic iodide is an effective, readily available and less expensive alternative to parenteral sodium iodide for patients in thyroid storm with upper gastrointestinal tract dysfunction.

Determination of free iodide in human serum: Separation from other I-species and quantification in serum pools and individual samples

A method for the determination of free iodide in human serum was developed. For this purpose iodide from pooled serum samples was separated from the organic manner by SEC. The iodide fraction subsequently was freeze-dried and analyzed by ion chromatography for quantification. Investigations for recovery and precision were carried out and were found to show sufficient results. For quality assurance ICP-MS was taken additionally as an total I-detector [1], using native and iodide-spiked serum samples. The iodide results of ICP-MS as well as those of IC were well corresponding. Iodine containing SEC-fractions from iodide-spiked samples showed no increased I-values except that in the iodide fractions, proving that there was no iodide conversion into other I-species (and vice versa) during the whole procedure. Free iodide from two serum pools of different healthy persons was determined as 2.25 and 2.43 mu g I-/L, respectively. The values are related to total iodine levels determined by ICP-MS. For comparative reasons a table of individual iodine and iodide values is presented.

An Efficient Gram Scale Synthesis of Aryl Iodides from Aryl Diazofluoroborates in Water Under Mild Conditions

Transition metal-free synthesis of synthetically valuable aryl iodides from aryl diazofluroborates in water under mild conditions has been described. Majority of synthesized aryl iodides are obtained in quantitative yields (>99 %) under present reaction conditions. The structural effects due to the substituents present on aryl diazofluoroborates did not show any satisfactory effect on the yields of the aryl iodides. Hence, the methodology presented here was found to be adventitious for the quantitative production of synthetically valuable aryl iodides.

O-glycoside synthesis with glycosyl iodides under neutral conditions in 1 M LiClO4 in CH2Cl2

Glycosyl phosphates, imidates, trifluoroacetates, chlorides, and bromides are converted into the respective glycosyl iodides by treatment with LiI or NaI in 1 M solutions of LiClO4 in CH2Cl2. Under these neutral conditions the reactive glycosyl iodides are activated, and react with different glycosyl acceptors to give O-glycosides in moderate yields, with the alpha-anomers predominating. The glycosylation reactions most probably proceed by the initial formation of beta-configured glycosyl iodides from the alpha-configured precursors, and subsequent attack of the glycosyl acceptor on the equatorial iodide from the axial direction.

Nanoparticles for nucleation of heavy metal iodide films: mercuric iodide and bismuth tri-iodide cases

Mercuric iodide and bismuth tri-iodide nanoparticles were synthesized by suspension in octadecene, from Hg(NO3)(2)center dot H2O and I-2, and from Bi(NO3)(3)center dot 5H(2)O and I-2, respectively. The best synthesis conditions were 2 hrs. at 60-70 degrees C, followed by 10 min. at 95-110 degrees C for mercuric iodide nanoparticles, and 4 hrs. at 80-110 degrees C, followed by 10 min. at 180-210 degrees C for bismuth tri-iodide ones. Nanoparticles were then washed and centrifugated with ether repeatedly. Compounds identity was confirmed by X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Nanoparticles were characterized by transmission (TEM) and scanning (SEM) electron microscopy. Disk-like and squared mercuric iodide nanostructures were obtained, 80-140 nm and 100-125 nm in size respectively. Rounded and rod-like bismuth tri-iodide nanoparticles, 30-500 nm in size were obtained. Acetonitrile and isopropanol suspensions of mercuric iodide nanoparticles, and acetonitrile suspension of bismuth tri-iodide nanoparticles exhibited peak maxima shifts in their UV-Vis spectra, as was reported for nanoparticles of other materials. It is the first time that mercuric iodide and bismuth tri-iodide nanoparticles are synthesized by the suspension method, although uniform shape and size distributions have not yet been obtained. They offer interesting perspectives for crystalline film nucleation, for improving current applications of these materials, as far as for opening new ones.
