Mesoporous NiO electrodes were used in photoelectrochemical cells using iodide/triiodide-based redox electrolytes. Cathodic photocurrents were found upon visible light excitation. These photocurrents were enhanced when coumarin 343 dye was adsorbed at the NiO surface or when a unanchored dye (coumarin 337) was added to the electrolyte. The proposed reaction for photocurrent generation is as follows: in the absence of dyes, excitation of triiodide leads to the generation of diiodide radicals, which subsequently accept electrons from the NiO electrode. Enhanced photocurrent generation in the presence of dyes is possibly due to energy transfer from excited dye molecules to triiodide. Charge transport studies of C343-sensitized NiO suggest that hole transport in mesoporous NiO is due to hopping of positive charge between Ni-surface atoms.. ...
What is iodide?. Many people can recall iodine being applied to cuts and scrapes as children. Iodide is like chloride in that it is most comfortable in nature after it has acquired an extra electron and becomes negatively charged (I-).. What foods contain iodide?. The iodide content of foods is mostly related to the soil content in which plants were grown and/or the iodide content of any fertilizers used to cultivate the soil. Furthermore, the iodide content in drinking water usually reflects the iodide content of the rocks and soils through which the water runs or is maintained. Seafood is typically a better source of iodide than freshwater fish. Dairy foods may be a fair source of iodide, but the iodide content of cows milk reflects either the iodide content of the cows feed and/or the soil content of their grazing region. Iodide deficiency for the most part has been eradicated from many regions of the world including the United States, where iodide is added to salt. Check your salt label ...
The instability of NI3 and NI3 · NH3 can be attributed to the large steric strain caused by the three large iodine atoms being held in proximity to each other around the relatively tiny nitrogen atom. This results in a very low activation energy for its decomposition, a reaction made even more favorable due to the great stability of N2. Nitrogen triiodide has no practical commercial value due to its extreme shock sensitivity, making it impossible to store, transport, and utilize for controlled explosions. Whereas pure nitroglycerin is also greatly shock-sensitive (although not nearly as much so as nitrogen triiodide, which can be set off with the touch of a feather) and powerful, it was only due to phlegmatizers that its shock sensitivity was reduced and it became safer to handle and transport in the form of dynamite.. The decomposition of NI3 proceeds as follows to give nitrogen gas and iodine:. ...
Nitrogen triiodide explosion. Footage of a laboratory demonstrator making contact with a sample of nitrogen triiodide (NI3) to trigger a loud explosion. The initial explosion triggers secondary explosions on the other samples of NI3. The purple cloud is iodine vapour. Nitrogen gas is also produced. The instability of NI3, an example of a very sensitive contact explosive, is due to the steric strain of three relatively large iodine atoms bound to the relatively small nitrogen atom. - Stock Video Clip K004/5171

Abstract: Background: The sodium/iodide symporter (NIS) is a membrane glycoprotein mediating active iodide uptake in the thyroid gland and is the molecular basis for radioiodide imaging and therapeutic ablation of thyroid carcinomas. NIS is expressed in the lactating mammary gland and in many human breast tumors raising interest in similar use for diagnosis and treatment. However few human breast tumors have clinically evident iodide uptake ability. We previously identified PI3K signaling as important in NIS upregulation in transgenic mouse models of breast cancer and the PI3K pathway is commonly activated in human breast cancer. Methods: NIS expression subcellular localization and function were analyzed in MCF-7 human breast cancer cells and MCF-7 cells stably or transiently expressing PI3K p110alpha subunit using Western blot of whole cell lysate cell surface biotinylation Western blot and immunofluorescence and radioiodide uptake assay respectively. NIS localization was determined in a human ...

The sodium/iodide symporter (NIS) is a plasma membrane glycoprotein that mediates iodide (I-) transport in the thyroid, lactating breast, salivary glands, and stomach. Whereas NIS expression and regulation have been extensively investigated in healthy and neoplastic thyroid and breast tissues, little is known about NIS expression and function along the healthy and diseased gastrointestinal tract. Thus, we investigated NIS expression by immunohistochemical analysis in 155 gastrointestinal tissue samples and by immunoblot analysis in 17 gastric tumors from 83 patients. Regarding the healthy Gl tract, we observed NIS expression exclusively in the basolateral region of the gastric mucin-producing epithelial cells. In gastritis, positive NIS staining was observed in these cells both in the presence and absence of Helicobacter pylori. Significantly, NIS expression was absent in gastric cancer, independently of its histological type. Only focal faint NIS expression was detected in the direct vicinity of

The understanding of the mechanisms through which NIS expression is repressed in thyroid tumors is of importance because it could open new possibilities of improvement of 131 Iodide delivery to tumors with low or no radioiodide uptake activity. It is now well documented that NIS expression is primarily regulated at the level of transcription. The mechanisms of regulation operating on the transcription of the NIS gene are likely more complex than those governing transcription of other thyroid-specific genes (Tg, TPO, -). Factors interacting directly or indirectly with the most important regulatory region of the NIS gene named NUE (for NIS Upstream Enhancer) are only partially known. Pax-8 is probably the crucial regulatory factor that binds to NUE but its expression and function does not seem to be altered in thyroid carcinomas. The present article examines the involvement of two candidate proteins known to down regulate NIS expression: PTTG and PBF.. PTTG, initially found expressed in pituitary ...

Natrium Iodide Symporter is a plasma membrane glycoprotein. It transports two ions of sodium (Na+) and one of iodide (I-) and maintained by Na+/K+ ATPase [1], [2], [3]. In thyroid cells, NIS plays a pivotal role to accumulate iodine. Additionally, NIS is also expressed in breast cancer tissue and has been considered as a potential target for radioiodine therapy. However, NIS expression in breast cancer tissues had been reported to be varied between studies.. Furthermore, the molecular mechanism of NIS expression in breast cancer remains unclear [4]. Interestingly, it has been reported that NIS is highly expressed in invasive breast cancer tissues. A study by Tazebay et al. reported that indeed, there is a correlation between NIS expression and malignant transformation of human breast tissue [5], [6].. Other than the variation of NIS expression level between molecular subtypes of breast cancer, the location of NIS expression is another factor that may influence the uptake of radioiodine by breast ...

A sodium/iodide symporter (NIS), also known as a sodium/iodide cotransporter or solute carrier family 5, member 5 (SLC5A5) is a protein that in humans is encoded by the SLC5A5 gene. It is a transmembrane glycoprotein with a molecular weight of 87 kDa and 13 transmembrane domains, which transports two sodium cations (Na+) for each iodide anion (I−) into the cell. NIS mediated uptake of iodide into follicular cells of the thyroid gland is the first step in the synthesis of thyroid hormone. Iodine uptake mediated by thyroid follicular cells from the blood plasma is the first step for the synthesis of thyroid hormones. This ingested iodine is bound to serum proteins, especially to albumins.[citation needed] The rest of the iodine which remains unlinked and free in bloodstream, is removed from the body through urine (the kidney is essential in the removal of iodine from extracellular space). Iodine uptake is a result of an active transport mechanism mediated by the NIS protein, which is found in ...

Iodine is an essential element required for the function of all organ systems. Although the importance of iodine in thyroid hormone synthesis and reproduction is well known, its direct effects on the immune system are elusive. Human leukocytes expressed mRNA of iodide transporters (NIS and PENDRIN) and thyroid-related proteins [thyroglobulin (TG) and thyroid peroxidase (TPO)]. The mRNA levels of PENDRIN and TPO were increased whereas TG transcripts were decreased post leukocyte activation. Flow cytometric analysis revealed that both PENDRIN and NIS were expressed on the surface of leukocyte subsets with the highest expression occurring on monocytes and granulocytes. Treatment of leukocytes with sodium iodide (NaI) resulted in significant changes in immunity-related transcriptome with an emphasis on increased chemokine expression as probed with targeted RNASeq. Similarly, treatment of leukocytes with NaI or Lugols iodine induced increased protein production of both pro- and anti-inflammatory cytokines.
Radioiodinated bleomycin is a useful imaging agent for body tissues. Its production by iodination of bleomycin with radioactive iodide ions in the presence of an oxidizing agent is described.
From the results of this investigation the order of adsorption of the ions by precipitated barium sulphate is: ferrocyanide , nitrate , nitrite , chlorate , permanganate , ferricyanide , chloride , bromide , sulphocyanate , iodide, the ferrocyanide ion being adsorbed the most and iodide the least. From a consideration of this order and of the absolute amount of adsorption in each case we find very little reason to place much credence in Schulzes law. Although we find a quadrivalent ion the most strongly adsorbed, we find four univalent ions more strongly adsorbed than the trivalent ferricyanide. Furthermore, contrary to what is implied in Schulzes law, we find a very wide variation in the amount of univalent ions adsorbed. This amount varies from 8.482 gram anions per 100 mols for nitrate to 0.056 gram anions per 100 mols for iodide ion. If the adsorption values are expressed in gram anions instead of gram equivalent anions the order becomes: nitrates , nitrites , chlorate , ferrocyanide , ...
Its time to take a look at a vitally important nutrient that has been ignored for a number of years, until the recent nuclear crisis in Fukushima, Japan led to the release of radioactive particles that adversely affect human health. And that nutrient is Iodine. Iodine is a chemical element with symbol I and atomic number 53. Iodine is a member of the halogen family of elements, which also includes fluorine, chlorine, and bromine. Free iodine occurs mainly as a diatomic molecule I2, which exists only momentarily after being oxidized from iodide by an oxidant like free oxygen. Iodines high atomic number makes it a relatively rare element.. Iodine is found on Earth mainly as the highly water-soluble iodide ion which concentrates it in oceans and brine pools. Its presence in ocean water has given it an important role in biology. It is the heaviest essential element utilized widely by life in biological functions. Iodines rarity in many soils, due to initial low abundance as a crust-element, and ...
During an investigation into the mechanism of the biosynthesis of thyroid hormones, it became necessary to determine traces of iodide and bromide in biological matrices as well as in food. A vydac 302-IC anion-exchange column with methanesulphonic acid as the mobile phase was used for the ion chromatographic separation of iodide and bromide. A post-column reaction detector was developed based on the reaction between iodide or bromide, chloramine-T and 4,4-bis(dimethylamino)diphenylmethane. Methods with minimal sample preparation are described for determination of iodide or bromide in serum, milk, salt and water. The detection limit is ca. 20 pg iodide and 15 ng bromide injected.
