  1. 21. Minimally invasive aortic valve replacement

    Författare :Magnus Dalén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Minimally invasive aortic valve replacement (AVR) through a ministernotomy has been developed as an alternative approach to conventional full sternotomy AVR. During recent years, sutureless aortic bioprostheses were introduced with the aim to facilitate implantation, especially in minimally invasive procedures. LÄS MER

  3. 22. Development of a novel experimental technique for studying zeolites : combining zeolite coated ATR elements and FTIR spectroscopy

    Författare :Mattias Grahn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Thin zeolite films have great potential in several novel application areas such as structured catalysts, membranes and sensors. To fully exploit the advantages of these films it is of great importance to determine the adsorption properties of the films. LÄS MER

  4. 23. Structural studies of heterogeneous amyloid species of lysozymes and de novo protein albebetin and their cytotoxicity

    Författare :Vladimir Zamotin; Ludmilla Morozova-Roche; Daniel Otzen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amyloid; cytotoxicity; atomic force microscopy; Biophysics; Biofysik;

    Sammanfattning : A number of diseases are linked to protein folding problems which lead to the deposition of insoluble protein plaques in the brain or other organs. These diseases include prion diseases such as Creutzfeld-Jakob disease, Alzheimer's disease, Parkinson's disease and type II (non-insulin dependent) diabetes. LÄS MER

  5. 24. The subjective visual horizontal in the diagnosis of vestibular disorders : physiological and clinical considerations

    Författare :Arne Tribukait; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vestibular system; vestibular tests; vestibular neuritis; Meniere sdisease; gentamicin treatment; vestibular compensation; stapedotomy; spatial orientation; gravity otoliths; utricle; saccule; semicircular canals; subjective visual horizontal; roll;

    Sammanfattning : In the examination of patients with vestibular disturbances the diagnostic techniques are almost entirely focused on the semicircular canals. However, a considerable number of the patients have symptoms which are suggestive of an affection of the otolith organs, e.g. false sensations of tilt or linear motion and even sudden falls. LÄS MER

  7. 25. The role of the microenvironment in growth plate and articular chondrocyte differentiation

    Författare :Zelong Dou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One crucial process during skeletal development is joint formation. It starts with the interzone appearance characterized by high expression of Gdf5, Gli3, Wnt4 and Wnt9a, low expression of Col2a1 of the local compact elongated cells which subsequently give rise to most joint elements including articular cartilage as the ongoing joint cavitation.
