  1. 16. Cubic Response Theory and the Electromagnetic Properties of Ground and Excited States

    Författare :Dan Jonsson; Aage E. Hansen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is devoted to the study of analytical response theory up to third order and its application to electromagnetic properties of ground and excited states. Computationally tractable expressions for the cubic response function for SCF and MCSCF wave functions have been derived and implemented in a computer code. LÄS MER

  3. 17. Ropivacaine and cellular functions : towards an understanding of efficacy in ulcerative colitis

    Författare :Titti Martinsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Ulcerative colitis is an inflammatory condition affecting the mucosa of the colon and the disease is characterised by periods of active colonic inflammation, intermitted by periods of remission. Local anaesthetics have been shown to exhibit a wide array of anti inflammatory effects in addition to the reversible block of nerve impulse propagation, and some or maybe all of these may explain the reported beneficial effects of local anaesthetics in ulcerative colitis patients.

  4. 18. Obsessive-compulsive disorder : novel insights on executive functions, gut microbiome, and genetics

    Författare :Long-Long Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Obsessive-compulsive disorder (OCD) is characterized by intrusive thoughts and images, and repetitive, time-consuming compulsions. It causes disability and impaired quality of life. The neurobiological model of OCD revolves around dysfunctional brain circuits, referred to as the cortico-striato-thalamocortical (CSTC) loop.

  5. 19. Wave Modelling Techniques for Medium and High Frequency Vibroacoustic Analysis Including Porous Materials

    Författare :Hao Liu; Svante Finnveden; Ines Lopez Arteaga; Mohamed Ichchou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Numerical methods based on wave modelling are explored for the vibroacoustic analysis of wave propagation, sound transmission and interior noise in vehicles and buildings at medium and high frequencies. The presence of sound absorbing porous materials in practical engineering structures is also considered. LÄS MER

  7. 20. Immunogenicity of biological therapies : frequency, predictability and clinical relevance in chronic inflammatory diseases

    Författare :Nicky Dunn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Over the past three decades, biologic therapies have revolutionised the treatment of chronic inflammatory diseases such as multiple sclerosis (MS), systemic lupus erythematosus (SLE), and anti-neutrophil cytoplasmic antibody (AAV)-associated vasculitis (AAV) and for many, are now a core component of management. However, unlike chemically synthesised smallmolecule drugs, biologicals are larger and are produced using complex processes in or from living organisms, resulting in a propensity to stimulate an unwanted immune response to itself or related proteins.
