21. Mesentric hemodynamics and effects of angiotensin II during circulatory stress
Sammanfattning : Mesenteric hypoperfusion and ischemia is considered to be deleterious to the intestinal mucosal barrier function and it is suggested that the renin-angiotensin system plays a pivotal role in the regulation of mesenteric perfusion.The present thesis examines the effects of the specific AT1 receptor blocker candesartan on mesenteric hemodynamics during acute hypovolemia and endotoxinemia.

22. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections
Sammanfattning : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. LÄS MER
23. Perfusion Chromatography of membrane proteins
Sammanfattning : According to genomics up to 40% of all eukaryotic proteins are membrane bound. Their isolation from the biomembrane is essential for structural and functional studies. The major task in membrane protein isolation is obtaining a pure and homogeneous population, while maintaining biological activity, native conformation, and keeping cofactors bound. LÄS MER
24. Placental Function : An Epidemiological and Magnetic Resonance Study
Sammanfattning : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. LÄS MER
25. Cerebral Perfusion during Cardiopulmonary Bypass
Sammanfattning : Impaired superior vena cava (SVC) cannula outflow during cardiopulmonary bypass (CPB) is a frequent issue, often manifested by only marginal changes in routine monitoring parameters. Nevertheless, significant impact on cerebral perfusion may result. LÄS MER
