  1. 1. Basement membrane components in the chondrocyte extracellular matrix

    Författare :Alexander Kvist; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skelett; rheumatology locomotion; nidogen; chondroitin sulfate; collagen assembly; Skeleton; muscle system; type IV collagen; laminin; perlecan; basement membranes; ECM; chondrcytes; muskelsystem; reumatologi;

    Sammanfattning : The extracellular matrix (ECM) is a network of macromolecules which, together with cells, forms the various tissues of all metazoan organisms. Cartilage, in contrast to most other tissues, contains relatively few cells in proportion to the volume occupied by ECM. LÄS MER

  3. 2. The surface complex of Euglena gracilis. Involvement in cellular movements and biochemical and molecular analyses of the components

    Författare :Silja K Petersen-Mahrt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UV-B radiation; tubulin; surface complex; plasma membrane; phylogeny; phototaxis; nitrogen deficiency; membrane skeleton; Euglena gracilis; actin; cell shape; Physiological biophysics; Växtfysiologi;

    Sammanfattning : The flagellate Euglena gracilis shows rhythms in phototaxis and cell shape changes between oblong and round. Artificial UV-B radiation of 0.5 W m-2 caused a loss in phototaxis, but the peak of activity occurred at the same time as for control cells. LÄS MER

  4. 3. Image processing methods to study the living hearing organ

    Författare :Miriam von Tiedemann; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis we are developing image processing methods allowing one to probe the structure and function of the mammalian hearing organ, an intricate cellular assembly with a highly specialized three-dimensional organization. Confocal as well as electron microscopy was used for image acquisition. LÄS MER

  5. 4. Studies on the phenotype and function of osteoclasts using osteopetrotic and rachitic animal models

    Författare :Karin Hollberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bone mineralization; bone resorption; osteoclast; tartrate-resistant acid phosphatase; proteolytic processing; cathepsin K; rickets; osteopetrosis; FGF-23;

    Sammanfattning : Osteoclasts are multinucleated bone-resorbing cells that have been implicated in a variety of skeletal diseases e.g. osteoporosis, rheumatoid arthritis and skeletal metastasis. Under physiological conditions, the osteoclast participates in ossification during longitudinal bone growth as well as in bone remodelling during adulthood. LÄS MER

  7. 5. Exported proteins of the malaria parasite Plasmodium falciparum : characterization of blood-stage antigen 332

    Författare :Sandra Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Plasmodium falciparum malaria is one of the most important infectious diseases in the world. Following invasion of the human red blood cell (RBC), the P. LÄS MER
