  1. 6. Small-Scale Absorbed Dose Modelling in Selective Internal Radiation Therapy : Microsphere Distribution in Normal Liver Tissue

    Sammanfattning : Radioembolisation (RE), with yttrium-90 (90Y) labelled microspheres, is an increasingly common treatment method for unresectable liver tumours. The tolerable mean absorbed dose for normal liver (NL) tissue is higher in RE than in External Beam Radiation Therapy (EBRT); absorbed dose heterogeneity is thought to be one important reason, together with a low absorbed dose rate, but the knowledge of microsphere distributions is limited.

    Sammanfattning : Specific molecular recognition materials are important in analytical applications. It has been a longstanding dream for scientific explorers to realise a versatile method to generate materials that can recognize biological and chemical substance of interests. LÄS MER

  4. 8. Microcirculation in native and transplanted rodent pancreatic islets with special reference to the influence of diabetes mellitus

    Författare :Per-Ola Carlsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; islet microcirculation; microspheres; micropuncture technique; islet blood flow; islet capillary pressure; oxygen tension; transplanted islets; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The aim of the present work was to characterize the islet microcirculation in animal models of type 1 and type 2 diabetes, as well as in islets transplanted to diabetic or normoglycemic recipients. For this purpose, a microsphere technique was evaluated and applied for measurements of islet blood flow in mice. LÄS MER

    Författare :Anna Imberg; Per Hansson; Krister Thuresson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

    Sammanfattning : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. LÄS MER
