BACKGROUND Methylation of sodium iodide symporter promoter has been reported to increase the incidence of papillary thyroid carcinoma (PTC). In this meta-analysis stratified via methylation of sodium iodide symporter promoter, we evaluate the relationship between methylation of sodium iodide symporter promoter and PTC. The association between methylation with aggressiveness and metastasis poten...

Thyroid cancer is the most common malignant tumor of the endocrine system and the incidence has been increasing in recent years. In a great part of the differentiated carcinomas, thyrocytes are capable of uptaking iodide. In these cases, the main therapeutic approach includes thyroidectomy followed by ablative therapy with radioiodine. However, in part of the patients, the capacity to concentra...

In this work, the steady state S0-S1 and S0-S2 absorption and emission behaviour of the water-soluble tetrakis(N-methyl-4-pyridyl)porphyrin zinc(ii) tetrachloride (ZnTMPyP) in media of constant and high ionic strength, both with and without iodide ions as a fluorescence quencher, was measured. The quenching of the ZnTMPyP S1 state by iodide ions proceeds primarily through diffusion-limited inte...

Thyroid iodide uptake is basic to the clinical applications of radioiodine. Iodide uptake occurs across the membrane of the thyroid follicular cells through an active transporter process mediated by the sodium iodide symporter (NIS). The recent cloning of the NIS gene enabled the better characterization of the molecular mechanisms underlying iodide transport, thus opening the way to the clarifi...

Background: Iodide transport defect (ITD) is a dyshormonogenetic congenital hypothyroidism caused by sodium/iodide symporter (NIS) gene mutations. In the lactating mammary gland, iodide is concentrated by NIS, and iodine for thyroid hormone synthesis is thereby supplied to the infant in the breast milk. Case Description: A 34-year-old Japanese woman was diagnosed with ITD caused by a homozygous...

Methyl iodide (CH3I) is the most abundant organo-iodine compound in the atmosphere and is influential in aerosol formation and tropospheric ozone depletion. It is used in the production of pesticides and pharmaceuticals and is also produced biogenically by marine algae and terrestrial vegetation and soils. Short and long-term methyl iodide exposure via inhalation can be harmful to humans. In or...

In the crystal structure of the title compound, C(7)H(7)N(2) (+)·I(-)·H(2)O, [C(7)H(7)N(2) (+)](n) chains extending along the a-axis direction are linked via N-H⋯N hydrogen bonds. The cations are further connected to the anions by N-H⋯I, N-H⋯O and O-H⋯I hydrogen bonds, leading to the formation of a sheet parallel to the ac plane. π-π inter-actions [centroid-centroid distance = 3.8378 (7) Å] lin...

The crystal structure of the title compound, C(7)H(10)NO(+)·I(-), displays N-H⋯I hydrogen bonds between the 4-meth-oxy-anilinium cations and the iodide anion together with weaker C-H⋯π contacts.

In the crystal structure of the title salt, C2H8NO(+)·I(-), N-H⋯O, N-H⋯I and O-H⋯I hydrogen bonds lead to the formation of layers staggered along the c axis.

The asymmetric unit of the title compound, C(19)H(19)NP(+)·I(-), contains two tetra-alkyl-phospho-nium cations and two I(-) anions. The P atoms are four-coordinated in distorted tetra-hedral configurations by three phenyl and one methyl C atoms. There are weak intra- and inter-molecular N-H⋯I contacts.
