16. Studies of diaphragm fatigue and dysfunction
Sammanfattning : Diaphragm fatigue and dysfunction are important components of acute and chronic respiratory pump failure. We lack knowledge about the nature of diaphragm fatigue and the pathophysiological and morphological changes that occur in the diaphragm after prolonged mechanical ventilation. This thesis studied two aspects of diaphragm function. LÄS MER
17. Improving medical abortion : using mifepristone in combination with a prostaglandin analogue

19. The role of nitric oxide in the gastrointestinal tract
Sammanfattning : Nitric oxide (NO) is an important second messenger involved in the regulation of a multitude of mechanisms in the body, such as neurotransmission, smooth muscle contractility, host defense and immune regulation. Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), are chronic disorders affecting the gastrointestinal (GI) tract with unknown etiology. LÄS MER
20. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle
Sammanfattning : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. LÄS MER
