  2. 6. NMR studies of host-pathogen interactions

    Author : Katja Petzold; Jürgen Schleucher; Torleif Härd; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; regulatory RNA; HBV; H.pylori; phospholipids; ROESY; Molecular biophysics; Molekylär biofysik; biokemi; Biochemistry;

    Abstract : This thesis describes the use of Nuclear Magnetic Resonance (NMR) for characterizing two host-pathogen interactions: The behavior of a regulatory RNA of the Hepatitis B virus (HBV) and the attachment of Helicobacter pylori (H. pylori) to the gastric mucosa. READ MORE

  4. 7. Molecular Dynamic Simulations of Biological Membranes

    Author : Qaiser Waheed; Olof Edholm; Friederike Schmid; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phospholipids; area compressibility; undulations; quantum corrections; cholesterol; phase transition; segregation;

    Abstract : Biological membranes mainly constituent lipid molecules along with some proteins and steroles. The properties of the pure lipid bilayers as well as in the presence of other constituents (in case of two or three component systems) are very important to be studied carefully to model these systems and compare them with the realistic systems.

  5. 8. Studies on antibodies against phospholipids

    Author : Leopold Årfors; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Antiphospholipid syndrome; anticardiolipin antibodies; lupus anticoagulants; platelets; platelet activation; complement activation; endothelial cells; thromboxane; prostacyclin; acetylsalicylic acid.;

    Abstract : The main clinical features of the antiphospholipid syndrome (APLS) are arterial and venous thrombosis, repeated spontaneous abortions and thrombocytopenia. Diagnosed concomitant with an underlying disease the designation is secondary APLS; otherwise primary APLS. READ MORE

  6. 9. Dynamics of Biomembranes and Rheological Properties of Living Cells

    Author : Peter Berntsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell mechanics; lipid dynamics; cell rheology; biomembranes; water dynamics; relaxations; phospholipids; glass transition;

    Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE

  7. 10. Detection of Lipids and Proteins on Biological Surfaces using Imaging Mass Spectrometry

    Author : Louise M Carlred; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ToF-SIMS; GM1; cholesterol; Amyloid-β; phospholipids; Imaging Mass Spectrometry; Alzheimer’s disease; sulfatides; QCM-D; MALDI;

    Abstract : Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a technique that can be used for imaging the spatial distribution of many different molecules at the same time. It is very sensitive for detection of small biomolecules, such as lipids, whereas larger biomolecules, such as peptides and proteins, cannot be detected as intact entities due to fragmentation.
