  1. 6. Metabolism-dependent activation of food and environmental mutagens in endothelial cells

    Författare :Anita Annas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : The endothelial cells of blood vessels have been proposed as a target for toxic effects ofxenobiotics in the cardiovascular system. In the present studies, induction of cytochromeP450 1A (CYP1A) enzymes and metabolic activation of food and environmentalmutagens were examined in endothelial cells of rodents, birds, and humans.

  3. 7. Endothelial and cardiac effects of 5-fluorouracil. An experimental and clinical study

    Författare :Sara Kinhult; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; oncology; Cytology; endothelin; onkologi; Cytologi; cancer; von Willebrand factor; thrombomodulin; lipoperoxidation; probucol; low-molecular weight heparin; scanning electron microscopy; 5-fluorouracil; endothelium;

    Sammanfattning : The cytostatic drug 5-fluorouracil (5-FU) has been shown to affect both morphology and function of vascular endothelium. These effects could be part of the pathophysiology for 5-FU induced cardiotoxicity. The present thesis explores the mechanisms of this endothelial toxicity. LÄS MER

  4. 8. Antibiotics and infusion phlebitis. Clinical and experimental studies

    Författare :Peter Lanbeck; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; HUVEC; endothelium vascular; Infektioner; ICAM-1; 3H-thymidine incorporation; cloxacillin; dicloxacillin; phlebitis epidemiology; Antibiotics; phlebitis chemically induced;

    Sammanfattning : Intravenous administration of antibiotics is often followed by infusion phlebitis. In this condition are vessel irritation, inflammation and sometimes superficial thrombosis included. In this thesis, the risk for infusion phlebitis for various antibiotics has been evaluated in a clinical study in 550 patients. LÄS MER

  5. 9. Mechanism behind the development of radiation-induced cardiovascular effects

    Författare :Venkata Ramesh Yentrapalli; Siamak Haghdoost; Andrzej Wojcik; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Epidemiological studies on acutely and chronically exposed individuals indicate that ionising radiation could be a risk factor for cardiovascular diseases. Experimental data regarding radiation-induced cardiovascular late effects are limited and biological mechanisms behind these late effects are still unclear. LÄS MER

  7. 10. Bioactivation and binding of polycyclic aromatic hydrocarbons in blood vessel endothelia

    Författare :Lizette Granberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Polycyclic aromatic hydrocarbon; PAH; endothelial cells; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants formed by incomplete combustion of organic materials such as fossil fuels and wood. Experimental and epidemiological studies indicate that PAHs may be involved in the development of cardiovascular disease. LÄS MER
