  1. 11. Quantitative 31P magnetic resonance spectroscopy in diffuse liver disease

    Författare :Bengt Norén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The studies in this thesis were delineated to evaluate the diagnostic possibilities in patients with diffuse liver disease by using phosphorus-31 MR spectroscopy and comparing the results with clinical, laboratory and histopathological findings. For this purpose in all 38 patients and 25 controls without evidence of liver disease were examined. LÄS MER

  3. 12. Genomic and non-genomic effects of a new sodium-sensing network in renal and lung epithelia

    Författare :Kristina Eneling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sodium and water homeostasis is crucial for cell function, survival and health of the individual. The kidney is responsible for sodium regulation in the body, balancing sodium secretion and reabsorption, and thereby also regulating the blood pressure, primarily via the Na+, K -ATPase. LÄS MER

  4. 13. Non-Invasive Assessment of Liver Fibrosis with 31P-Magnetic Resonance Spectroscopy and Dynamic Contrast Enhanced Magnetic Resonance Imaging

    Författare :Bengt Norén; Staffan Wirell; Peter Lundberg; Peter Leander; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The present study aims at demonstrating phosphorus metabolite concentration changes and alterations in uptake/excretion of a hepatocyte specific contrast agent in patients with diffuse - or suspected diffuse - liver disease by applying two non-invasive quantitative MR techniques and to compare the results with histo-pathological findings, with focus on liver fibrosis.In the first study phosphorus-31 MR spectroscopy using slice selection (DRESS) was implemented.

    Sammanfattning : 5-aminolevulinic acid (5-ALA) and derivatives thereof are widely usedprodrugs in treatment of pre-malignant skin diseases of the cancer treatmentmethod photodynamic therapy (PDT). The target molecule in 5-ALAPDTis protoporphyrin IX (PpIX), which is synthesized endogenously from5-ALA via the heme pathway in the cell. LÄS MER

  7. 15. Physicochemical properties of root fiber suspensions. A comparison between parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius)

    Författare :Alejandra Castro; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; parsnip; yacon; plant suspensions; particle size distribution; rheology; fructans; dietary fiber;

    Sammanfattning : The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in these two roots, and possibly encourage their further industrial use.
