  4. 4. Energy metabolic failure within the arterial wall in atherosclerosis

    Detta är en avhandling från Göteborg

    Författare :Max Levin; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; hypoxia; hypoxia marker; bioluminescence imaging; ATP; glucose; lactate; energy metabolism;

    Sammanfattning : Atherosclerosis is a disease that affects large and medium sized arteries. The majority of deaths in a Western population can be directly attributed to complications of this disease. Although research efforts have been vast, the pathophysiological mechanisms underlying atherosclerosis are not fully understood. LÄS MER
