Iodide, as a biologically important anion, it remains a worthwhile yet challenging undertaking to find a sensitive and specific approach to provide a technically simple iodide detection. In this article, it was found that no other ions than iodide-induced anisotropic growth of gold nanocrystals (AuNCs) originated from a small molecule, histidine-mediated synthesis of AuNCs, were observed. Simul...

We report here a derivatization headspace method for the analysis of inorganic iodine in water. Samples from Lake Mead, the Las Vegas Wash, and from Las Vegas tap water were examined. Lake Mead and the Las Vegas Wash contained a mixture of both iodide and iodate. The average concentration of total inorganic iodine (TII) for Lake Mead was approximately 90 nM with an iodide-to-iodate ratio of app...

Erythrocytes are hemolyzed by myeloperand triiodothyronine-dependent, but not oxidase, an H203-generating system (gluin the chloride-dependent, systems. Hemocose + glucose oxidase; hypoxanthine + lysis is inhibited by the peroxidase inxanthine oxidase) and an oxidizable cohibitors, azide and cyanide, and by catafactor (chloride, iodide, thyroxine, tnlase and is stimulated by superoxide iodothyr...

An experiment was designed to examine a mechanism to improve embryonic survival following maternal thyroid hormone manipulation. Commercial turkey breeder hens were fed diets containing supplemental iodide to mimic changes in the maternal thyroid output during an egg production cycle (32 to 48 wk of age). Dietary iodide treatment depressed maternal blood thyroxine (T4) concentrations in a time-...

The aim of this study was to explore the correlations of iodide ions with vascular endothelial growth factor (VEGF) and its receptors during the proliferation of vascular endothelial cells (VECs). The proliferation rates of VECs in the presence of iodide ions and VEGF inhibitor were determined using the CCK-8 method. The effect of iodide ions on the phosphorylation of vascular endothelial growt...

Iodide is captured by thyrocytes through the Na(+)/I(-) symporter (NIS) before being released into the follicular lumen, where it is oxidized and incorporated into thyroglobulin for the production of thyroid hormones. Several reports point to pendrin as a candidate protein for iodide export from thyroid cells into the follicular lumen. Here, we show that a recently discovered Ca(2+)-activated a...
