Excited state electronic properties of sodium iodide and cesium iodide

We compute from first principles the dielectric function, loss function, lifetime and scattering rate of quasiparticles due to electronic losses, and secondary particle spectrum due to plasmon decay in two scintillating alkali halides, sodium iodide and cesium iodide. Particular emphasis is placed on quasiparticles within several multiples of the bandgap from the band edges. A theory for the decay spectra of plasmons and other electronic excitations in crystals is presented. Applications to Monte Carlo radiation transport codes are discussed.

Thyroid ultrasound and urinary iodide excretion in children and adolescents with diabetes mellitus (IDDM)

Background Date, studies on thyroid volume and urinary iodide excretion in patients with diabetes mellitus are not available. Sonographically determined parameters of the thyroid size are correlated to other anthropometrous data and the urinary iodide excretion is correlated to glucosuria, the HbA1c value and the diabetes duration. Method In this prospective study we evaluated sonographically the thyroid volume in 107 patients with type I diabetes mellitus and 112 healthy children. The urinary iodide excretion was measured photometrically by using a modified eerie ion arsenious acid method for spontaneous urinary specimen and if available for the 24 h collected urin. Results The thyroid volume depended on site and age. A positive correlation of the thyroid volume and age, body weight and height, could be demonstrated. Referring to reference data a goitre prevalence of 30% in juvenile patients with diabetes mellitus type I was detected. Interestingly, juvenile type I diabetics presented with an average urinary iodide excretion of 183,0 mu g iodide/g creatinine. Even the urinary iodide excretion of 162,5 mu g iodide confirmed this increased level. The urinary iodide excretion in 24 hours correlated with glucosuria and the HbA1c level. The healthy children presented with an average urinary iodide excretion of 42,6 mu g iodide/g creatinine. The mean value was clearly below the WHO recommendation of 150-300 mu g iodide/g creatinine. Only 2,8% of the healthy children examined exceeded the lower limit of this range. Conclusion In addition to the existing distinct under supply of iodide we assume an increased urinary iodide excretion in context with the osmotic diuresis in juvenile diabetics. Contrary to current opinion, that these data are correlated to the daily intake of iodide, which was calculated from urinary excretion rate, this thesis could not be affirmed for juvenile diabetics. Therefore it seems reasonable to frequently control thyroid volume and thyroid function in children and adolescents with diabetes mellitus.

Effects of marginal iodine deficiency during pregnancy: iodide uptake by the maternal and fetal thyroid

Iodide uptake by the thyroid is an active process. Iodine deficiency and pregnancy are known to influence thyroid hormone metabolism. The aim of this study was to clarify the effects of iodine deficiency and pregnancy on iodide uptake by the thyroid. Radioiodide was injected intravenously into nonpregnant and 19-day pregnant rats receiving a normal or marginally iodine-deficient diet. The uptake of radioiodide by the thyroid was measured continuously for 4 h. The absolute iodide uptake by the maternal and fetal thyroid glands at 24 h was calculated by means of the urinary specific activity. Pregnancy resulted in a decrease in the absolute thyroidal iodide uptake. Marginal iodine deficiency had no effect on the absolute iodide uptake by the maternal thyroid. The decreased plasma inorganic iodide was compensated by an increase in thyroidal clearance. A similar compensation was not found for the fetus; the uptake of iodide by the fetal thyroid decreased by 50% during marginal iodine deficiency. This can lead to diminished thyroid hormone production, which will have a negative effect on fetal development, especially of the brain.

Acyl Iodides in Organic Synthesis. Reaction of Acetyl Iodide with Thiols

The direction of reactions of acetyl iodide with aliphatic, aromatic, and heterocyclic thiols is determined by the thiol acidity and steric factors. Acetyl iodide reacted with aliphatic thiols, including trialkylsilyl-substituted derivatives R(CH2)(n)SH (R = Me, n = 3; R = Me3Si, n = 3; R = Et3Si, n = 2), to give the corresponding ethanethioates R(CH2)(n)SCOMe. Benzenethiol was oxidized with acetyl iodide to diphenyl disulfide. The reaction of acetyl iodide with 2-sulfanylethanol afforded 2-(2-iodoethyldisulfanyl)ethyl acetate as a result of three consecutive-parallel processes: acylation, iodination, and oxidation of the initial compound. 1,3-Benzothiazole-2-thiol reacted with acetyl iodide only at the nitrogen atom to give quaternary salt, whereas the SH group remained intact.

Thermal effect in beta-selective glycosylation reactions using glycosyl iodides

The unique reactivity of glycosyl iodides and the fact that they react under neutral conditions makes them the donors of choice in our glycosylation strategies. Glycosyl iodides are generated in situ from either the anomeric acetate or the anomeric silylated derivative yielding the alpha-iodide. In the reported glycosylation reactions, protected glucosyl, galactosyl, and mannosyl iodides were reacted with trimethylene oxide as the acceptor, yielding the beta-anomer as the major product. In the absence of neighboring group participation, beta-selectivity is thought to arise from nucleophilic displacement of the alpha-iodide in an S(N)2-like mechanism, while the alpha-product is the result of nucleophilic attack on the beta-iodide. In this study, increased beta-selectivity using an inverse thermal effect is demonstrated. (c) 2005 Elsevier Ltd. All rights reserved.

Sodium Iodide Symporter (NIS) in Gastric Mucosa: Gastric Iodide Secretion

Iodide is actively transported from the bloodstream into the gastric juice and some iodide accumulation occurs in the gastric wall, but no uptake of iodide takes place in the gastric lumen. The cDNA-sequence of the thyroid sodium iodide symporter (NIS) was revealed in 1996 and, in the thyroid gland, iodide is actively transported into the thyrocyte by NIS. Later on NIS was also found to be present, in large amounts, in the gastric mucosa, where it is located basolaterally in the surface epithelial cells. Iodide transport over the gastric mucosa is attenuated by the selective competitive NIS inhibitor perchlorate, and also by ouabain, an inhibitor of Na+/K+-ATPase, which powers NIS transport. Thus, gastric iodide secretion is to a large extent mediated by NIS. The regulation of gastric NIS expression is still unknown. The functional role of NIS in the gastric mucosa is uncertain, but several theories have been put forward. These include mediating recirculation of iodide, as well as securing the presence of iodide in the stomach for antimicrobial or antioxidative purposes. Gastric iodide secretion may also be a protecting mechanism against developing gastric cancer. Gastric NIS has further been suggested to be an important protein for transporting anions other than iodide, i.e., nitrate. In the future NIS expression, or lack thereof, may become a useful parameter in the diagnosis of gastric cancer. Gene transfer of NIS into cancer cells without NIS expression, as well as chemical induction of NIS expression, are methods under exploration. If means to regulate NIS expression in tumor cells are found, it may become possible to use radioiodine therapy in gastric cancer.

Differential gene expression analysis of iodide-treated rat thyroid follicular cell line PCCl3

The inhibitory effect of supraphysiological iodide concentrations on thyroid hormone synthesis (Wolff – Chaikoff effect) and on thyrocyte proliferation is largely known as iodine autoregulation. However, the molecular mechanisms by which iodide modulates thyroid function remain unclear. In this paper, we analyze the transcriptome profile of the rat follicular cell lineage PCCl3 under untreated and treated conditions with 10 (- 3) M sodium iodide (NaI). Serial analysis of gene expression (SAGE) revealed 84 transcripts differentially expressed in response to iodide (p <= 0.001). We also showed that iodide excess inhibits the expression of essential genes for thyroid differentiation: Tshr, Nis, Tg, and Tpo. Relative expression of 14 of 20 transcripts selected by SAGE was confirmed by real-time PCR. Considering the key role of iodide organification in thyroid physiology, we also observed that both the oxidized form of iodide and iodide per se are responsible for gene expression modulation in response to iodide excess.

Efficacy of methyl iodide and synergy with chloropicrin for control of fungi

Efficacy of soil fumigation with methyl bromide and methyl iodide against Botrytis cinerea, Colletotrichum gloeosporioides, Fusarium oxysporum, Gliocladium virens, Phytophthora citricola, Phytophthora citrophthora, Pythium ultimum, Rhizoctonia solani and Verticillium dahliae was determined in laboratory experiments in closed fumigation chambers. Pythium ultimum was the most sensitive fungal species with EC50 values for methyl bromide and methyl iodide of 15.5 and 8.6 mu M, respectively. R solani was the least sensitive with EC50 values of 253.4 and 161.4 mu M for methyl bromide and methyl iodide, respectively. Relative potency ([methyl bromide]/[methyl iodide]) values ranged from 5.2 for P citricola to 1.5 for F oxysporum. Methyl iodide was 2.7 more efficacious than methyl bromide averaged over all fungal species. Methyl bromide/chloropicrin and methyl iodide/chloropicrin applied jointly were 2.2 and 2.8 times more efficacious, respectively, against F oxysporum than when the compounds were applied singly. Combining methyl bromide and methyl iodide with chloropicrin resulted in a significant synergistic increase in activity against F oxysporum. (C) 2000 Society of Chemical Industry.
