background: to assess accessibility of iodinated salt and urinary iodine concentrations (uic) during pregnancy. this cross-sectional study was carried out between october and december, 2009 in urmia county, west azerbaijan (wa), iran. methods: data on demographic characteristics and iodinated salt accessibility were gathered through a questionnaire at 1st trimester. household salt samples and u...

Hypervalent iodine compounds are powerful reagents for the development of novel transformations. As they exhibit low toxicity, high functional group tolerance, and stability in biocompatible media, have been used functionalization biomolecules. Herein, we report recent advances up to June 2021 peptide protein modification using hypervalent reagents. Their use as transfer or oxidizing is discuss...

Many methods for the determination of iodinated compounds in thyroid extracts by paper and thin-layer chromatography have been reported. Some of them do not separate inorganic iodide (l-3)) diiodothyronine (4-8)) or monoand di-iodotyrosines (6, 9). Others use more than one solvent system (4, 7, lO-12), usually one system for iodotyrosines and another for iodothyronines. Still other show poor se...

The reactivities of N-iodosuccinimide and iodine with various goitrogenic compounds were studied with dimethylsulfoxide through which nitrogen had been bubbled as a solvent. Although iodine does not react with all of the compounds, N-iodosuccinimide does react with all of them. N-Iodosuccinimide may, therefore, serve as an interesting model for the "active iodine" of the thyroid. The thyroid gl...
