The sodium (Na)/iodide (I)-symporter (NIS) is abundantly expressed and accumulates iodide in thyroid follicular cells. The NIS is also found in extrathyroidal tissues, particularly gastric mucosa. Controversies exist on the localization of extrathyroidal NIS. We have studied the presence of both NIS peptide and NIS messenger RNA (mRNA) in the digestive tract and thyroid from different mammals. ...

BACKGROUND Placental transport of iodide is required for fetal thyroid hormone production. The sodium iodide symporter (NIS) mediates active iodide transport into the thyroid and the lactating mammary gland and is also present in placenta. NIS is competitively inhibited by thiocyanate from maternal smoking, but compensatory autoregulation of iodide transport differs between organs. The extent o...

Investigation of the optical response metal-perovskite configuration-based hyperbolic metamaterials (HMMs) was made toward achieving nearly-perfect absorption in 300-900 nm wavelength span. More precisely, HMM structure comprised periodically arranged gold (Au) and methyl ammonium lead iodide (MAPbI3) nanolayers taken. The results were derived by exploiting effective medium theory transfer matr...

sorption reactions in many heterogeneous systems are important. adsorption is a time dependent process and knowing the adsorption rate is essential for designing, evaluating and recovering the adsorbents. at the present study, an ammonium adsorption kinetic experiment by some soils series of golestan provice, which is varying in mineralogical and textural properties was conducted using solution...

a simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using dmso, tbai in the presence of k2co3. we extended the utility of  potassium carbonate as an efficient base for the preparation of ethers. a wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl halid...

Herein, the synthesis of methylammonium-free and bromide-free CsxFA1?xPbI3 (FA for formamidinium) perovskite (PVK) photovoltaic layers with intrinsic outstanding properties in terms crystallinity, defect waiving/passivation, ionic mobility blocking by using a coadditives approach is described. It consists mixing two chloride additives PVK precursor solution: potassium (KCl) ammonium (NH4Cl). KC...

Abstract Organic- inorganic hybrid perovskite shows promising properties such as optical, electrical, and magnetic. To address issues in the standard methylammonium lead iodide toxicity stability, was replaced with Cu metal ion part iodine by chlorine anionic position. In this work, methyl ammonium copper chloride (MA 2 CuCl 4 ) phenyl ethyl (PEA were synthesised. Optical structural property va...

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...
