6. Cancer Risk Assessment of Glycidol : Evaluation of a Multiplicative Risk Model for Genotoxic Compounds
Sammanfattning : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. LÄS MER
7. The effect on chromosomal stability of some dietary constituents
Sammanfattning : When food is heated, a vast number of compounds are formed. Some of these are known to be toxic. Among these are furan, HMF, PhIP, IQ, and MeIQx, the subjects of this thesis. All these compounds are known or suspected carcinogens but the detailed mechanisms behind their carcinogenicity have not yet been fully examined. LÄS MER
8. Particularly harmful particles? A study of airborne particles with a focus on genotoxicity and oxidative stress
Sammanfattning : Today it is well established that particulate matter (PM) cause a wide range of health effects. The underlying mechanisms likely include inflammation, oxidative stress and genotoxicity. There is however a lack of knowledge regarding how particles from different sources contribute to these effects. LÄS MER
9. Health of municipal sewage workers : Studies of cancer incidence, biomarkers of carcinogenicity and genotoxicity, and self reported symptoms
Sammanfattning : The occupational exposures of sewage workers are complex and variable, and include a great variety of biological and chemical agents. Previous research has focused mostly on infections and various symptoms among sewage workers, e.g. abdominal and respiratory symptoms. LÄS MER
10. Characterization of toxicological effects of a novel in vivo benzo[a]pyrene metabolite in colonic cells
Sammanfattning : Cancer of the colon and rectum is the third most common cancer form in the world. Where the majority of cases fall into the category of sporadic colorectal cancer (CRC), lifestyle and diet have been found to be important risk factors associated with CRC. LÄS MER
