  1. 21. Computed Tomography of the Coronary Arteries : Developmental and Prognostic Investigations

    Författare :Mårten Sandstedt; Anders Persson; Joakim Alfredsson; Magnus Janzon; Jan Engvall; Mats Lidén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Computed tomography (CT) is an increasingly used modality for investigations of patients with suspected coronary artery disease (CAD). Technical advances could improve diagnostic accuracy and lead to clinical workflow improvements. Also, more prognostic information can optimize clinical follow-up strategies and treatments. LÄS MER

  3. 22. Mechanical optimization of orthopaedic bone screw constructs

    Författare :Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. LÄS MER

  4. 23. Dynamic changes in T cell compartments and new approaches in evaluating DSS induced and Gai2 deficient colitis

    Författare :Maria Fritsch Fredin; Göteborgs universitet; []
    Nyckelord :colitis; Gai2- - mice; dextran sodium sulfate; ex vivo cultures; micro-Computed Tomography; IEL; thymus; Inflammatory Bowel Disease;

    Sammanfattning : The overall aim of this thesis was to increase the understanding of the immunopathology of Inflammatory Bowel Disease (IBD). The first aim was to elucidate how the thymus and the gut epithelium were affected by colitis. The second aim was to investigate new ways of assessing and monitoring colitis. LÄS MER

  5. 24. Mechanisms of pain in autoimmunity : the role of antibodies

    Författare :Gustaf Wigerblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chronic pain in autoimmune diseases, like rheumatoid arthritis (RA), is a common and life- changing problem for many patients. Treatment is usually aimed at reducing inflammation and preserving the function of affected tissues. Chronic pain, however, often persists despite optimal disease control. LÄS MER

  7. 25. 3D visualization of vascular lesions and the role of versican in pulmonary arterial hypertension

    Författare :Christian Westöö; Kärlväggsbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pulmonary arterial hypertension; Synchrotron; Imaging; Phase-contrast; Plexiform; Versican;

    Sammanfattning : Pulmonary arterial hypertension (PAH) is a condition that leads to lethal right heart failure. Available treatments provide relief but are far from curative and the vascular remodeling in PAH has been difficult to decipher. LÄS MER
