1. Intrarenal oxygen homeostasis in acute and chronic kidney disease
Sammanfattning : Renal hypoxia has been recognized as a common feature of acute and chronic kidney injury arising from varying etiologies. It has also been proposed to provide a driving mechanism for the transition from acute to chronic kidney disease (CKD). LÄS MER
2. The Role of Dopamine-Metabolising Enzymes in Renal Sodium Handling. An Experimental Study in vivo
Sammanfattning : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. LÄS MER
3. Diabetes-induced Alterations in Renal Microcirculation and Metabolism
Sammanfattning : Diabetes-induced renal complications, i.e. diabetes nephropathy, are a major cause of morbidity and mortality. The exact mechanism mediating the negative influence of hyperglycaemia on renal function is unclear, although several hypotheses have been postulated. LÄS MER
4. Physiology of Adventure Racing : with emphasis on circulatory response and cardiac fatigue
Sammanfattning : The overall aims of this thesis were to elucidate the circulatory responses to ultra-endurance exercise (Adventure Racing), and furthermore, to contribute to the clarification of the so called “exercise-induced cardiac fatigue” in relation to said exercise. An Adventure race (AR) varies in duration from six hours to over six days, in which the participants have to navigate through a number of check-points over a pre-set course, using a combination of three or more endurance/outdoor sports, e.

5. The Role of Mitochondrial Uncoupling in the Development of Diabetic Nephropathy
Sammanfattning : Diabetes is closely associated with increased oxidative stress, especially originating from the mitochondria. A mechanism to reduce increased mitochondria superoxide production is to reduce the mitochondria membrane potential by releasing protons across the mitochondria membrane. LÄS MER
