  1. 21. Degradation Mechanism and Effects of Vitamin E addition in UHMWPE Hip Implants

    Författare :Yannick Luisetto; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; Polymerteknik; biopolymers;

    Sammanfattning : Wear of the UHMWPE component is one of the major concerns in joint replacement surgery, triggering prosthetic loosening leading to revision. The understanding of the mechanisms of material degradation, especially in regard to oxidation, is one of the keys to significantly improve the mechanical properties. LÄS MER

  3. 22. Cellular effects after exposure to mixed beams of ionizing radiation

    Författare :Elina Staaf; Andrzej Wojcik; Siamak Haghdoost; Eva Forssell-Aronsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; high LET; low LET; mixed beams; combined exposure; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. LÄS MER

  4. 23. Pharmacokinetics and dosimetry in intraperitoneal radioimmunotherapy with 211At

    Författare :Elin Cederkrantz; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; radioimmunotherapy; alpha-emitter; ovarian cancer; MX35; pharmacokinetics; dosimetry; effective dose;

    Sammanfattning : The prognosis for patients diagnosed with disseminated cancer is often poor. Radioimmunotherapy (RIT) is a new approach to treat disseminated disease. The aim is to target tumor cells with monoclonal antibodies (mAbs) labeled with radionuclides which release cytotoxic particle radiation upon decay. The radionuclide 211At, with half-life 7. LÄS MER

  5. 24. DNA repair and genome organisation in mammalian cells : studies involving single-cell electrophoresis

    Författare :Stefan Eriksson; Bert van Zeeland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Biology; fysikalisk biologi;

    Sammanfattning : The comet assay (single-cell electrophoresis) is a comparably new method for measurement of DNA strand breakage, primarily in eukaryotic cells. Its main advantage is that it works on the single-cell level, making it possible to detect heterogeneity in DNA damage induction and repair. LÄS MER

  7. 25. Novel Modes of Immune Activation in Anopheles gambiae and Drosophila melanogaster

    Författare :Bo Lindberg; Ingrid Faye; Kenneth Vernick; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Malaria is a disease of poverty and continues to plague a great part of the world’s population. An increased understanding of the interactions between the vector mosquito, the malaria parasite, and also the mosquito gut microbiota are pivotal for the development of novel measures against the disease.
