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

    Author : Bengt Norén; Staffan Wirell; Peter Lundberg; Peter Leander; Linköpings universitet; []
    Keywords : ;

    Abstract : 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.

  4. 2. Improving Assessments of Hemodynamics and Vascular Disease

    Author : Magnus Ziegler; Petter Dyverfeldt; Tino Ebbers; Jonas Lantz; Ebo de Muinck; Carljohan Carlhäll; Alex J. Barker; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. READ MORE

  5. 3. Diabetes in 3D : β-cell mass assessments in disease models & evaluation of SPECT based imaging

    Author : Saba Parween; Ulf Ahlgren; Helena Edlund; Eckhard Lammert; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optical projection tomography; Diabetes; β-cell mass; disease etiology; 3D imaging; radiotracers; Single photon emission computed tomography; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. READ MORE

  6. 4. Laser Doppler imaging of patch tests : a methodological and comparative study with visual assessments

    Author : Bolli Bjarnason; Karolinska Institutet; Karolinska Institutet; []
    Keywords : skin perfusion; laser Doppler perfusion imaging; laser Doppler perfusion scanning; contact dermatitis; patch test technique; test procedure; test method; test system; patch test optimization; serial dilution; dose; exposure time; application time; reading time; immunosuppression; pigmented patch test materials; edge effect; nickel; isothiazolinones; corticosteroids; budesonide; neomycin; balsam of Peru;

    Abstract : Optimal test technique for most allergens is lacking. Despite technological progress in the 20th century, patch tests are habitually still assessed visually. Morphology of definite positive patch tests is unknown, reflected by various reading scales available and false-positive tests. READ MORE

  7. 5. Applying emerging genetic methods to wild model systems

    Author : Ida-Maria Blåhed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Genetic material is an invaluable source of information for assessments of wild populations. By using information derived from genetic markers, individuals can be identified and tracked over time, enabling studies of a wide range of behavioral, ecological, and evolutionary processes.
