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