  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. Interactions of iodine and methyl iodide with reactive metals

    Författare :Henrik Glänneskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the event of a severe nuclear reactor accident, iodine will be released from the fuel into the containment building. If released to the environment, iodine represents a biological hazard due to the concentration in the thyroid gland. Being a reactive element, iodine will undergo reactions with water, oxygen, organic material, surfaces etc. LÄS MER

  4. 3. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxy paint; Methyl iodide; Iodine source term; Organic iodides; Severe nuclear accidents;

    Sammanfattning : During severe nuclear reactor accidents such as Chernobyl or Fukushima large amounts of radioactive iodine can be released in form of inorganic and organic iodine species into the environment. Volatile radioactive iodine species are harmful to human health when inhaled. LÄS MER

  5. 4. Methods for the Synthesis of PET Tracers and NMR Studies of Ribonuclease A

    Författare :Linda Samuelsson; Bengt Långström; Sharon Stone-Elander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; [11C]methyl iodide; Stille reaction; palladium; Ribonuclease A; osmolytes; PFG-NMR; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis contains two parts.In the first part, general and versatile palladium-mediated 11C-C bond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. LÄS MER

  7. 5. Transition Metal Mediated Transformations of Carboranes

    Författare :Ludvig Eriksson; Kalman Szabo; Uppsala universitet; []
