  1. 1. Spectral Image Processing with Applications in Biotechnology and Pathology

    Författare :Milan Gavrilovic; Carolina Wählby; Ewert Bengtsson; Ingrid Carlbom; Robert Murphy; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color theory; light microscopy; spectral imaging; image analysis; digital image processing; mathematical modeling; estimation; noise models; spectral decomposition; color decomposition; colocalization; cross-talk; autofluorescence; tissue separation; prostate cancer; biomedical applications; molecular biotechnology; histopathology; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Color theory was first formalized in the seventeenth century by Isaac Newton just a couple of decades after the first microscope was built. But it was not until the twentieth century that technological advances led to the integration of color theory, optical spectroscopy and light microscopy through spectral image processing. LÄS MER

  2. 2. Glucose degradation products in patients on hemodialysis : interventional studies

    Författare :Bernd Ramsauer; Bernd Stegmayr; Henrik Hadimeri; Bengt Lindholm; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hemodialysis; advanced glycation end products; skin autofluorescence; plasma autofluorescence; glucose degradation products;

    Sammanfattning : Hemodialysis (HD) is the most frequently used treatment for end-stage renal disease. Despite all efforts to improve the outcomes, the mortality of patients on HD is still high, and this especially is related to cardiovascular diseases (CVD). LÄS MER

  3. 3. Iron and macrophages in atherogenesis

    Författare :Xi Ming Yuan; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Oxidation of low density lipoprotein (LDL) may result in its uptake by macrophages and ensuing foam cell formation. Thus, oxidised LDL may play an important role in atherogenesis. Extensive in vitro evidences are in favour of the notion that LDL oxidation by cells present in atherosclerotic plaques requires the presence of transition metals. LÄS MER

  4. 4. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Författare :Johan Axelsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Sammanfattning : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. LÄS MER

  5. 5. Free radicals in cellular pathology : Mechanisms behind lipofucin formation in cultured myocardial cells

    Författare :Rasi Marzabadi Massoud; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Lipofuscin, or age pigment, may be defined as a yellowish-brown,autofluorescent, protein and lipid containing pigment that accumulates inthe lysosomal vacuome of a variety of post-mitotic cell types in man andanimals during aging. Lipofuscin is the end product of peroxidation,fragmentation and polymerization of proteins and lipids. LÄS MER
