   Abstract : Pancreas transplantation is today a technically successful procedure and provides an alternative to insulin injections for the treatment of Type I diabetes mellitus. This thesis was undertaken while pancreas transplantation was developing and while several fundamental questions were being asked about both endocrine and exocrine drainage of the transplanted pancreas as well as how best to diagnose and prevent rejection.

4. 2. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects

   Author : Anders Wåhlin; Anders Eklund; Jan Malm; Richard Birgander; William G Bradley; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arterial Pulsatility; cerebrospinal fluid; cerebral blood flow; venous flow; intracranial pressure; pulse pressure; dementia; hippocampus; multiple sclerosis; magnetic resonance imaging; radiofysik; radiation physics;

   Abstract : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. READ MORE

5. 3. Cerebral perfusion during cardiopulmonary bypass with special reference to blood flow

   Author : Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Dan Lindblom; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Cardiopulmonary bypass (CPB) is an important method that enables open heart surgery. There is a risk of neurological complications, and efforts to minimize those include optimization of the cerebral perfusion during CPB. READ MORE

6. 4. The Impact of Pancreatic Islet Vascular Heterogeneity on Beta Cell Function and Disease

   Author : Sara Ullsten; Per-Ola Carlsson; Joey Lau; Sara Bohman; Rebecca L. Hull; Uppsala universitet; []
   Keywords : Pancreatic islets; heterogeneity; islet vascularity; blood flow; islet transplantation; islet amyloid; insulitis; type 1 diabetes; beta cell proliferation; Medicinsk vetenskap; Medical Science;

   Abstract : Diabetes Mellitus is a group of complex and heterogeneous metabolic disorders characterized by hyperglycemia. Even though the condition has been extensively studied, its causes and complex pathologies are still not fully understood. The occurring damage to the pancreatic islets is strikingly heterogeneous.
