THE INFLUENCE OF LEAD IODIDE AEROSOL DISPERSITY ON ITS ICE-FORMING ACTIVITY

Lead iodide aerosol ice-forming activity obtained by thermocondensation in a cloud chamber has been studied. Lead iodide aerosols have been found to yield a maximum number of 2 x 10(18) kg-1 of ice crystals at 253 K. At 263 K the maximum output amounts to 3 x 10(16) kg-1 and at 268 K lead iodide aerosols are generally inert. Ice-forming characteristics of the lead iodide are inferior to those of silver iodide and copper acetylacetonate, but are better than those of phloroglucinol and copper sulphide. The possibility of producing ice-forming nuclei with 10-fold reduced lead iodide content is considered by coating inert nuclei with small quantities of active substance. The activity of such coated nuclei is estimated.

IODIDE BUFFER SYSTEMS FOR THE CALIBRATION OF IODIDE-SELECTIVE ELECTRODES

A new approach to the creation of anion buffer systems is proposed, which extends the linear range. The new iodide buffer systems, containing (1) HgI2 precipitate, CaEDTA(2-), Ca2+, HgEDTA(2-), and (2) HgI2 precipitate, chloride complexes of Hg2+ and excess of Cl- ions, are proposed for the calibration of iodide-selective electrodes at pI > 5. It is shown with the help of these buffers, that a solid-state Orion 94-53 iodide-selective electrode keeps linear Nemstian response up to pI = 7.5. Iodide buffer systems are used for the estimation of the reliability of literature data on selectivity coefficients of iodide-selective electrodes with respect to Cl- ions.

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.

According to the thermodynamics analysis, the molar enthalpy change, the molar entropy increase, the Gibbs free energy change and the balance constant of indium iodide polycrystal synthesis reaction were calculated in order to evaluate the feasibility of reaction temperature on 653 K. After the temperature 653 K was applied in the synthesis experiment, indium iodide polycrystal was successfully obtained by the two-zone vapor transporting method. The result of X-ray diffraction analysis indicates the temperature 653K can be used for indium iodide polycrystal synthesis.

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.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 144-48-9, you can contact me at any time and look forward to more communication. Formula: C2H4INO.

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.

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.
