  1. 16. Identification of novel inducers for LL-37 expression : assay development and mechanistic studies

    Författare :Frank Nylén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The remaining reservoir of effective antibiotics is running out and more and more pathogens are gaining resistance, even to the last line of antibiotics. Therefore, novel treatment regimens against bacterial infections are urgently needed. LÄS MER

  3. 17. Dynamic Modelling of Physical Processes in Magmatic Systems: Dyke Emplacement and Flow-Induced Crystal Rotations

    Författare :Rémi Vachon; Christoph F. Hieronymus; Janine Kavanagh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical solutions; elasticity and anelesticity; fracturing; magmatic plumbing system; sheet-like intrusions; rheology of the crust; physics of magma; solid mechanics; fluid flow; crystal rotation;

    Sammanfattning : The main motivation for this thesis is to develop and improve numerical tools and methods that help further our comprehension of the volcanic plumbing system and its dynamics.The commonly used standard elastic model predicts solutions of dyke shape, thickness, over-pressure and fracturing criteria that do not always fit natural observations.

  4. 18. Influenza A virus in natural and artificial environments

    Författare :John Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Influenza is caused by influenza A virus, a single stranded RNA virus of the orthomyxoviridae family. In humans, it causes yearly outbreaks with high morbidity and excess fatality rates as a direct effect. Placed in its ecological niche however, in dabbling ducks, avian influenza virus (AIV) induce quite mild disease. LÄS MER

  5. 19. Bartonella Infections in Sweden: : Clinical Investigations and Molecular Epidemiology

    Författare :Christian Ehrenborg; Martin Holmberg; Göran Friman; Eva Hjelm; Gunnar Sandström; Uppsala universitet; []
    Nyckelord :Communicable diseases; Bartonella; clinical studies; molecular epidemiology; Infektionssjukdomar;

    Sammanfattning : Characteristically, in infections that are caused by the zoonotic pathogen Bartonella naturally infected reservoir hosts are asymptomatic, where infected incidental, non-natural, hosts develop symptomatic disease. Cat-scratch disease (CSD) is a well known example. LÄS MER

  7. 20. Transmission routes and vector potential of the poultry red mite Dermanyssus gallinae

    Författare :Sara Brännström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The poultry red mite, Dermanyssus gallinae is a blood-feeding ectoparasite causing irritation, stress, and in severe infection, anemia and death of its avian host. This parasite not only causes welfare problems in poultry but also financial losses in egg production worldwide. The aims of this thesis were to elucidate the transmission routes of D. LÄS MER
