  3. 22. Radiobiological effects of the thyroid gland - transcriptomic and proteomic responses to 131l and 211At exposure

    Författare :Nils Rudqvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; iodine-131; radionuclide therapy; nuclear medicine; environmental exposure; thyroid; radiation biology; transcriptomics; proteomics; ionizing radiation; toxicity; normal tissue damage; microarray; LC-MS; biomarker;

    Sammanfattning : Radionuclides are widely used in medicine. 131I is one of the most employed radionuclides and is administered to patients either bound to tumor targeting molecules or as halide to target the thyroid or thyroid cancer. LÄS MER

  4. 23. Biomarker discovery and assessment for prediction of kidney response after 177Lu-octreotate therapy

    Författare :Emil Schüler; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PRRT; somatostatin; radionuclide therapy; 177Lu-octreotate; scintigraphy; renal function; toxicity; kidney response; radiation biology; microarray; molecular biomarkers; ionizing radiation; miRNA; proteomics; transcriptional response;

    Sammanfattning : Patients suffering from neuroendocrine tumors are oftentimes presented with spread disease at the time of diagnosis. Therapy using somatostatin analogs is today the only potentially curative treatment option for these patients. LÄS MER

  5. 24. Ionizing Radiation in Concrete and Concrete Buildings : Empirical Assessments

    Författare :Magnus Döse; Johan Silfwerbrand; Erik Sturkell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : One of the major issues with radiation from the natural isotopes 40K, 226Ra (238U) and 232Th and their decay products is the forthcoming legislation from the European Commission in relation to its Basic Safety Directive (2014). The European legislation is mandatory and could not be overthrown by national legislation. LÄS MER

  7. 25. Short and long-term effects of exposure to low dose and low dose rate of gamma radiation : using in vitro and in vivo models

    Författare :Traimate Sangsuwan; Siamak Haghdoost; Eva Forssell-Aronsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Low dose; Low dose rate; High dose rate; Ionizing radiation; Adaptive response; Senescence; Premature senescence; Oxidative stress; Drosophila embryo; Mutation; DNA repair; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Assessment of human health risks from exposure to ionizing radiation (IR) is mainly based on the extrapolation of results from epidemiological studies on populations exposed to relatively high doses and often at high dose rates (HDR). Risk estimates after exposure to low doses and in particular at low dose rates (LDR) remain controversial due to a lack of epidemiological evidence. LÄS MER
