  1. 6. Factors modifying cellular response to ionizing radiation

    Författare :Lei Cheng; Andrzej Wojcik; Siamak Haghdoost; Lovisa Lundholm; Penelope A. Jeggo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiation biology; DNA damage; gene expression; alpha particles; X-rays; mixed beams; gamma rays; hypothermia; dose rate.; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many physical factors influence the biological effect of exposure to ionizing radiation, including radiation quality, dose rate and temperature. This thesis focuses on how these factors influence the outcome of exposure and the mechanisms behind the cellular response. LÄS MER

  4. 8. Alpha-radioimmunotherapy with At-211: Evaluations and imaging on normal tissues and tumors

    Författare :Tom Bäck; Göteborgs universitet; []
    Nyckelord :radioimmunotherapy; astatine; RBE; renal function; GFR; imaging; targeted radiotherapy; alpha-RIT;

    Sammanfattning : Alpha-radioimmunotherapy (alpha-RIT) is an internal conformal radiotherapy at the cellular level using alpha-particle emitting radionuclides. Alpha-particles have a very short range in tissues (... LÄS MER

  5. 9. Alpha-1-microglobulin, heme-binding protein, reductase and antioxidant

    Författare :Maria Allhorn; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reduction; inflammation; chronic ulcers; collagen; low density lipoproteins; Medicin människa och djur ; Medicine human and vertebrates ; antioxidation; heme; hemoglobin; alpha-1-microglobulin; lipocalin;

    Sammanfattning : This thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. LÄS MER

  7. 10. Radiobiological effects of alpha-particles from Astatine-211: From DNA damage to cell death

    Författare :Kristina Claesson; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : ABSTRACT In recent years, the use of high linear energy transfer (LET) radiation for radiotherapeutic applications has gained increased interest. Astatine-211 (211At) is an -particle emitting radionuclide, promising for targeted radioimmunotherapy of isolated tumor cells and microscopic clusters. LÄS MER
