1. Focal atrial tachycardia : Insights concerning the arrhythmogenic substrate based on analysis of intracardiac electrograms and inflammatory markers
Abstract : Background: Focal atrial tachycardias are tachycardias characterized by a radial spread of activation from a discrete area of the atrial myocardium. They account for 10-15% of supraventricular tachycardias and are generally poorly responsive to pharmacological treatment. The pathophysiologic substrate of these arrhythmias remains poorly understood. READ MORE

2. Astrocyte metabolism following focal cerebral ischemia
Abstract : Stroke is one of the leading causes of disability and death. Most often, stroke results from blockage of an artery in the brain leading to tissue infarction within the perfusion territory of the affected vessel. READ MORE

3. Hyperglycemia and Focal Brain Ischemia : Clinical and Experimental Studies
Abstract : Diabetes is a major risk factor for ischemic stroke and is associated with increased mortality. Additionally, hyperglycemia, a common complication in acute stroke, is associated with poor outcome. READ MORE

4. Signal Transduction in Focal Cerebral Ischemia : Experimental Studies on VEGF, MAPK and Src family kinases
Abstract : Cerebral ischemia elicits a wide range of events, including complex activation of various intracellular signaling pathways. This study aims to investigate the expression of vascular endothelial growth factor (VEGF) and the activation pattern of mitogen-activated protein kinases (MAPK) in reponse to focal cerebral ischemia.

5. 11C Molecular Imaging in Focal Epilepsy
Abstract : Epilepsy is a common neurological disease affecting 6 million people in Europe. Early prevention and accurate diagnosis and treatment are of importance to obtain seizure freedom. In this thesis new applications of carbon-11-labelled tracers in PET and autoradiographic studies were explored in focal epilepsy. READ MORE
