1. Cardiovascular and metabolic effects of endothelins in man : an experimental and clinical study
Abstract : Increased plasma concentrations of endothelin-1 (ET-1) and of its propeptide big endothelin-1 have been reported in diseases associated with endothelial dysfunction, cardiovascular remodelling and insulin resistance. In this thesis, we studied the hemodynamic effects of big ET-1 in healthy humans focusing on the mechanisms of the effects (study I-IV). READ MORE

2. Metabolic intervention with amino acids in coronary surgery : A clinical study with special reference to effects of glutamate and aspartate on myocardial metabolism
Abstract : Amino acids, particularly glutamate and aspartate, have been suggested to be important for the tolerance to myocardial ischemia and for the recovery of the oxidative metabolism of the heart after ischemia. The objective of the present work was to investigate myocardial metabolism and how it is influenced by intravenous supply of glutamate and aspartate in association with coronary artery bypass grafting (CABG).

3. Quantitation of gluconeogenesis in humans
Abstract : Several methods have been introduced for estimating gluconeogenesis, but none provides a direct measurement without assumptions that condition the accuracy of the estimate. The aim of this work has been to develop a new method for quantitative studies of gluconeogenesis, applicable in humans. READ MORE

4. Spatio-Temporal Scale-Space Theory
Abstract : This thesis addresses two important topics in developing a systematic space-time geometric approach to real-time, low-level motion vision. The first one concerns measuring of image flow, while the second one focuses on how to find low level features. READ MORE

5. Consequences of Arterial Switch Operation in Children Born with Transposition of the Great Arteries
Abstract : Abstract Background: The introduction of the arterial switch operation (ASO) made it the procedure of choice for surgical correction of transposition of the great arteries. A majority of the sympathetic nerves innervate the heart alongside the great vessels; these are therefore likely to be damaged during the surgical procedure; imposing new challenges and questions that need to be addressed.
