2. 1. Quantum Chemical Studies of Protein-Bound Chromophores, UV-Light Induced DNA Damages, and Lignin Formation

   Author : Bo Durbeej; Leif Eriksson; Tim Clark; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; quantum chemistry; calculations; density functional theory; excited states; photochemistry; chromophores; absorption spectra; bathochromic shift; isomerization; UV radiation; DNA damages; cycloaddition reactions; photoenzymic repair; electron transfer; lignin; polymerization; phenoxy radicals; dilignols; Kvantkemi; Quantum chemistry; Kvantkemi;

   Abstract : Quantum chemical methods have been used to provide a better understanding of the photochemistry of astaxanthin and phytochromobilin; the photoenzymic repair of UV-light induced DNA damages; and the formation of lignin. The carotenoid astaxanthin (AXT) is responsible for the colouration of lobster shell. READ MORE

4. 2. Factors related to the occurrence of gastric adenocarcinoma subtypes

5. 3. Cancer risks in Swedish pesticide applicators in agriculture, forestry and gardening : a toxicological and epidemiological approach

   Author : Jan Dich; Karolinska Institutet; Karolinska Institutet; []
   Keywords : pesticide applicators; cancer incidence; Hodgkin s disease; non-Hodgkin s lymphoma; soft tissue sarcoma; prostate cancer; pesticides; phenoxy acid herbicides; organochlorine insecticides; occupational exposure; protective equipment; smoking habits;

   Abstract : The aims of this thesis were (1) to study the cancer risks in Swedish pesticide applicators, which is one of the occupational groups that is most exposed to pesticides in Sweden. This could be done by utilizing a complete register kept by the Swedish Board of Agriculture which include 20,245 subjects with licenses issued between 1965 and 1976, for epidemiological studies.

6. 4. Occupational exposures and malignant lymphoma

   Author : Bodil Persson; Östergötlands Läns Landsting; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The incidence of malignant lymphoma, especially non-Hodgkin's lymphoma (NHL) has increased over the last few decades. This statement is true despite the fact that methods for diagnosing malignant lymphoma has changed and misclassification has been a problem. READ MORE

7. 5. Cancer risks and immunological effects in agriculture

   Author : Laura Settimi Dionisi; Helge Kjuus; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : In general, farmers and agricultural workers are characterized by relatively low mortality rates when considering all causes of death and deaths due to all types of cancer. However, several studies have shown that this occupational category tend to be at increased risks of developing the following forms of malignancies: leukaemia, lymphomas, multiple myeloma, and cancers of the skin, lip, prostate, stomach, brain, and connective tissue.
