  1. 6. Systemic inflammatory activation during cardiac Surgery. Influence of cardiopulmonary bypass management and patient factors

    Författare :Martin Westerberg; Göteborgs universitet; []
    Nyckelord :cardiopulmonary bypass; inflammatory response; coagulation; CABG; cardiotomy suction; cytokines;

    Sammanfattning : Cardiac surgery with cardiopulmonary bypass is accompanied by a prominent systemic inflammatory and hemostatic activation, which may contribute to postoperative complications. Aims: To investigate if selection of cardiopulmonary bypass (CPB) system and management of cardiotomy suction (CTS) and mediastinal shed blood (MSB) affect systemic inflammatory response. LÄS MER

  3. 7. Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations

    Författare :Shirin Abbasinejad Enger; Hans Lundqvist; Anders Ahnesjö; Irena Gudowska; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; External Beam Radiotherapy; Gadolinium Neutron Capture Therapy; Gadolinium Neutron Capture Brachytherapy; Targeted Radionuclide therapy; Detector Response Modelling; Monte Carlo Simulation.; Radiological physics; Radiofysik;

    Sammanfattning : Developing radiation delivery systems for optimisation of absorbed dose to the target without normal tissue toxicity requires advanced calculations for transport of radiation. In this thesis absorbed dose and fluence in different radiotherapy applications were calculated by using Monte Carlo (MC) simulations. LÄS MER

  4. 8. Chloromethane Complexation by Cryptophanes : Host-Guest Chemistry Investigated by NMR and Quantum Chemical Calculations

    Författare :Zoltan Takacs; Jozef Kowalewski; Mikael Akke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host–guest complexes; inclusion phenomenon; cryptophanes; NMR; kinetics; activation energy; dipolar interaction; exchange; quantum chemical optimization; calculated chemical shifts; NOESY; cavity size; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Host–guest complexes are widely investigated because of their importance in many industrial applications. The investigation of their physico–chemical properties helps understanding the inclusion phenomenon. The hosts investigated in this work are cryptophane molecules possessing a hydrophobic cavity.

  5. 9. Multimethodological imaging studies of pathophysiological mechanisms in human epilepsy

    Författare :Carolina Ciumas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Although the pathophysiological mechanisms of human epilepsy are extensively investigated, many questions remain unanswered. One is whether idiopathic generalized epilepsies (IGE) have anatomical substrates. Another is if the functional integrity of the limbic networks in mesial temporal lobe epilepsy (MTLE) is impaired.

  7. 10. Development of vaccines and mouse models for chronic hepatitis C virus infection

    Författare :Sepideh Levander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chronic hepatitis C virus (HCV) infection is a major causative agent for severe liver disease and cancer worldwide. Globally, it is estimated that approximately 185 million people are infected with HCV and 130-170 million of these are chronic carriers of the virus (1, 2). LÄS MER
