  1. 6. Radiation induced biomarkers of individual sensitivity to radiation therapy

    Författare :Sara Skiöld; Mats Harms-Ringdahl; Siamak Haghdoost; Mats Ljungman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; low dose ionizing radiation; radiation sensitivity; proteomics; whole blood; 8-oxo-dG; oxidative stress; acute adverse healthy tissue effects; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Fifty percent of solid cancers are treated with radiation therapy (RT). The dose used in RT is adjusted to the most sensitive individuals so that not more than 5% of the patients will have severe adverse healthy tissue effects. LÄS MER

  3. 7. Low-Dose Ionizing Radiation Induces Neurotoxicity in the Neonate : Acute or fractionated doses and interaction with xenobiotics in mice

    Författare :Sonja Buratovic; Per Eriksson; Henrik Viberg; Bo Stenerlöw; Anders Fredriksson; Jean-René Jourdain; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Neonatal; Neurotoxicity; Behaviour; Nicotine; Ketamine; Mouse; Cognition; Acute irradiation; Fractionated irradiation;

    Sammanfattning : This thesis examines the developmental neurotoxic effects of exposure to low-dose ionizing radiation (IR), alone or together with xenobiotics, during a critical period of neonatal brain development in mice.During mammalian brain development there is a period called the brain growth spurt (BGS), which involves extensive growth and maturation of the brain.

  4. 8. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths

    Författare :Theres Lindgren; David Eriksson; Torgny Stigbrand; Bo Stenerlöw; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitotic catastrophe; senescence; cell cycle checkpoint; apoptosis; radiation; gene expression; p53; immunologi; Immunology; radiofysik; radiation physics;

    Sammanfattning : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. LÄS MER

  5. 9. Methodological aspects on excess cancer riskafter exposure to ionizing radiation

    Författare :Erik Holmberg; Göteborgs universitet; []
    Nyckelord :ionizing radiation; skin haemangioma; breast cancer; parathyroid adenoma; excess cancer risk; bias; confounding; risk models; pooled analysis.;

    Sammanfattning : Aims. The aims of this study were to establish a cohort of persons treated with radiotherapy for skin haemangioma in childhood and study the excess risk of cancer after exposure to ionizing radiation. LÄS MER

  7. 10. Ethical aspects of radiation protection

    Författare :Per Wikman-Svahn; John Cantwell; Gustaf Arrhenius; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Radiation; risk; ethics; Philosophy subjects; Filosofiämnen;

    Sammanfattning : This aim of this thesis is to examine ethical aspects of radiation protection from ionizing radiation. Radiation protection is the professional field that deals with the protection of humans and the environment from the harmful effects of radiation. LÄS MER
