1. Natural products from nonracemie building blocks : synthesis of pine sawfly pheromones
Abstract : This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis.

2. Ventricular Depolarization in Ischemic Heart Disease.Value of Electrocardiography in Assessment of Severity and Extent of Acute Myocardial Ischemia
Abstract : Background In patients with symptoms compatible with acute myocardial infarction (MI), early triage by ECG in the pre-hospital phase by ST-segment elevation myocardial infarction (STEMI) criteria is important for direct transport of these patients to a regional center for primary percutaneous coronary intervention (pPCI). The time from first medical contact to pPCI should, due to present guidelines, be no longer than two hours. READ MORE

3. Magnetic relaxation studies of self-associating and membrane proteins
Abstract : Magnetic relaxation dispersion measurements have been performed on aqueous protein solutions to study the dynamics of waters in the proton transport channel of bacteriorhodopsin and the self-association of the proteins BPTI, lysozyme and beta-lactoglobulin. The measurements have focused on the bulk relaxation rates, R1 and R2, of three water nuclei 1H, 2H and 17O that are coupled to the protein environments by exchange and therefore report on properties such as the protein tumbling and dynamics of internal waters.

4. Rectal cancer : Aspects of surgery and radiotherapy
Abstract : In rectal cancer, local failure is one of the principle causes of morbidity and mortality. The use of radiotherapy as an adjuvant treatment in resectable rectal cancer is extensively studied in order to lower unacceptably high local failure rates. READ MORE
