  1. 1. SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa

    Författare :Malin Josefsson; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ussing chamber; MNNG; gastric iodide secretion; ouabain; gastric cancer; sodium perchlorate; gastric NIS; bile duct cancer; Sodium iodide symporter;

    Sammanfattning : ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. LÄS MER

  3. 2. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

    Författare :Mats Jansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

    Sammanfattning : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. LÄS MER

  5. 4. In vitro studies on the mechanisms of inhibited thyroidal iodide uptake and destructive thyroiditis as adverse effects of amiodarone and interferon-gamma

    Författare :Sofia Tedelind; Göteborgs universitet; []
    Nyckelord :thyroid; amiodarone; interferon-gamma; iodide transport; tight junction; mitochondria; endocytosis;

    Sammanfattning : The clinical use of the potent anti-arrhythmic drug amiodarone is limited due to adverse effects e.g. in the thyroid comprising both hypo- and hyperthyroidism. Amiodarone-induced thyroid dysfunction can occur in subjects with normal thyroid glands but also in those with an underlying thyroid abnormality resulting in an aggravation of the condition. LÄS MER

  7. 5. Synthesis, Structure and Bonding in Polyiodides and Binary Metal Iodide-Iodine Systems

    Författare :Per H Svensson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum chemical calculations; vibrational spectroscopy; EXAFS; X-ray diffraction; charge-transfer; Polyiodides; binary metal iodide-iodine systems; Organisk kemi; Organic chemistry;

    Sammanfattning : Polyiodides and binary metal iodide-iodine compounds have been prepared and investigated by means of X-ray diffraction, EXAFS, far-IR, Raman, UV-vis and NMR spectroscopy and quantum chemical calculations. (Et3S)[AuI4].2I2 and (Me3S)[Cd2I6]1/2. LÄS MER
