    Nyckelord :Erythrocyte deformability; viscometry; Filtrometry; Red cell membrane; Buffer; Filtration pressure; stress factors; Mean corpuscular volume; Sodium-potassium pump; Ouabain; Corticosteroids; Blood storage; Transfusion; MEDICINE; MEDICIN;

    Sammanfattning : DOCTORAL DISSERTATION  Abstract The present thesis concerns factors of major importance in filtrometric studies of human erythrocytes, e.g. influence of buffer media, importance of filtration pressure for filtration through micropores and possible effects of damaged and hemolyzed blood cells.

  3. 7. Nephrotic syndrome in children : functional, morphological and therapeutical aspects

    Författare :Eva Löwenborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Children; glomerular volume; glomerular filtration rate; effective renal plasma flow; rats; nephrotic syndrome; cyclosporine; nephrotoxicity;

    Sammanfattning : Although cure rates of the idiopathic nephrotic syndrome in children have improved because of advances in immunosuppressive therapy, the pathogenesis and course of the disease remain controversial. We have followed children with nephrotic syndrome to study renal function and morphological changes in kidney biopsies and in an experimental study. LÄS MER

  4. 8. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

    Författare :Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

    Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.

  5. 9. The role of catecholamines in regulation of renal tubular sodium transport

    Författare :Ulla Holtbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :sodium balance; Na ; H -antiporter; Na ; K -ATPase; renal proximaltubules; hormonal regulation.;

    Sammanfattning : Renal sodium metabolism, a major determinant of arterial blood pressure, is regulated with remarkable precision by a variety of endocrine, autocrine and neuronal factors. All these factors are known to regulate sodium metabolism by affecting the rate of renal tubular sodium reabsorption. LÄS MER

  7. 10. Glomerular expression profiling and novel proteins in normal mouse kidney and adriamycin-induced nephrosis

    Författare :Masatoshi Nukui; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Kidney glomeruli function as high-capacity molecular sieves through which plasma is filtered into the Bowman s space as primary urine. The glomerular filtration barrier is composed of glomerular endothelial cells, the glomerulus basement membrane and the podocyte cell layer. LÄS MER
