    Sammanfattning : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. LÄS MER

  5. 14. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Författare :Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Sammanfattning : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. LÄS MER

  7. 15. Structural studies of microbubbles and molecular chaperones using transmission electron microscopy

    Sammanfattning : Ultrasound contrast agents (CAs) are typically used in clinic for perfusion studies (blood flow through a specific region) and border delineating (differentiate borders between tissue structures) during cardiac imaging. The CAs used during ultrasound imaging usually consist of gas filled microbubbles (MBs) (diameter 1-5 μm) that are injected intravenously into the circulatory system. LÄS MER
