1. Evolving the Methodology for Detection of Primary DNA Damage : Development, adaptation and assessment of the single cell gel electrophoresis (comet) assay
Sammanfattning : Deoxyribonucleic acid (DNA) is one of the most important molecules in nature. It is the fundamental carrier of evolutionary information and constitutes the genetic blueprint of all living organisms. Being the sole source of information, it is vital for the cell to transmit the correct genetic information from generation to generation. LÄS MER
2. Programmed Cell Death in Xylem Development
Sammanfattning : Concerns about climate changes and scarcity of fossil fuels are rising. Hence wood is becoming an attractive source of renewable energy and raw material and these new dimensions have prompted increasing interest in wood formation in trees, in both the scientific community and wider public. LÄS MER
3. Application of Padlock Probe Based Nucleic Acid Analysis In Situ
Sammanfattning : The great variation displayed by nucleic acid molecules in human cells, and the continuous discovery of their impact on life, consequently require continuous refinements of molecular analysis techniques. Padlock probes and rolling circle amplification offer single nucleotide discrimination in situ, a high signal-to-noise ratio and localized detection within cells and tissues. LÄS MER
4. 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
5. 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
