sodium iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. patients receiving sodium iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. the major source of radiation dose from administration of iodine-131 is ext...

OBJECTIVE Interferon regulatory factor-1 (IRF-1) is a critical regulator of interferon-gamma(IFNgamma)-mediated immune responses. To determine whether IRF-1 is involved in the pathogenesis of thyroiditis in animal models, we evaluated the incidence of iodide-induced lymphocytic thyroiditis (LT) in non-obese diabetic (NOD) mice lacking IRF-1 as well as IRF-1 +/+ and +/- mice. DESIGN IRF-1 +/+,...

We have previously developed a human macrophage hybridoma model system to study the effect of HIV-1 infection on monocytic function. Upon coculture of one chronically (35 days postinfection) HIV-1-infected human macrophage hybridoma cell line, 43HIV, there was a dose-dependent decrease in the viability of cocultured Ag-stimulated T cells associated with an increase in DNA strand breaks. Enhance...

Adequate iodide supply and metabolism are essential for thyroid hormones synthesis. In thyrocytes, iodide uptake is mediated by the sodium-iodide symporter, but several proteins appear to be involved in iodide efflux. Previous studies demonstrated that pendrin is able to mediate apical efflux of iodide in thyrocytes. Acute iodide excess transiently impairs thyroid hormone synthesis, a phenomeno...

Recent studies have highlighted the impact of sea surface iodide concentrations on the deposition of ozone to the sea surface and the sea to air flux of reactive iodine. The use of models to predict this flux demands accurate, spatially distributed sea surface iodide concentrations, but to date, the observational data required to support this is sparse and mostly arises from independent studies...

Abstract: In this study, a greenhouse study was conducted to investigate the growth of Aloe vera with different content of nitrogen fertilizers. Treatments consisted of 0, 0.15, 0.29, 0.43, 0.57 and 0.71 g/pot ammonium nitrate and 0, 0.11, 0.22, 0.33, 0.43, 0.53 g/pot urea. Then the effects of nitrogen fertilizers on fresh weight, photosynthetic pigments and proline content were studied. The...

Ionosilica ionogels have been lately introduced as emerging all-ionic designer materials. They consist of an ionic liquid (IL) guest trapped within a solid ionosilica support host. In this work, we investigate the influence (i) nature and (ii) ionosilica/IL ratio on mobility confined IL. We report elaboration various via nonhydrolytic sol–gel process, using namely tris(3-(trimethoxysilyl)propyl...
