  3. 12. Leukocytes in Angiogenesis : Learning from Transplanted Pancreatic Islets

    Författare :Gustaf Christoffersson; Mia Phillipson; Kristian Pietras; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; pancreatic islet transplantation; islets of Langerhans; diabetes mellitus; leukocytes; neutrophils; macrophages; pericytes; MMP-9; VEGF-A; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Angiogenesis, the growth of new blood vessels, is a complex process involving several cell types and molecular signals. Excessive vascular growth is a problem in tumors, and insufficient vascularization hampers the function of transplanted insulin-producing pancreatic islets. LÄS MER

  4. 13. Mechanisms of alloxan diabetogenicity

    Författare :Kjell Grankvist; Inge-Bert Täljedal; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alloxan; catalase; experimental diabetes; free radicals; islets of Langerhans; rubidium accumulation; superoxide dismutase; Trypan Blue;

    Sammanfattning : Suspensions of pancreatic islet cells from ob/ob-mice were incubated with Trypan Blue. Microscope photometry showed that apparently viable cells excluded the dye completely, whereas the nuclei of non-viable cells accumulated Trypan Blue by a saturable process. LÄS MER

  5. 14. Effects of Free Fatty Acids on Insulin and Glucagon Secretion : – with special emphasis on the role of Free fatty acid receptor 1

    Sammanfattning : Prevalence of type 2 diabetes mellitus (T2DM) is still rising and even so in the juvenile population. Obesity is highly associated with increased risk for developing T2DM. LÄS MER

  7. 15. The Colours of Diabetes : advances and novel applications of molecular optical techniques for studies of the pancreas

    Författare :Christoffer Nord; Ulf Ahlgren; Ian Smyth; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optical projection tomography; Technique development; Near-infrared; 3D visualization; Biomedical imaging; ß-cell mass; Diabetes; Vibrational micro spectroscopy;

    Sammanfattning : Diabetes is a rapidly increasing health problem. In a global perspective,approximately 415 million people suffered from diabetes in 2015 and this number ispredicted to increase to 640 million by 2040. To tackle this pandemic there is a needfor better analytical tools by which we can increase our understanding of the disease. LÄS MER
