6. Energy-metabolic aspects of ischemia and pre-treatment: studies in porcine myocardium
Abstract : The focus of this thesis is to clarify mechanisms involved in protective pre-treatment of ischemia by carbon monoxide (CO) and ischemic preconditioning (IP), so that new pro-tective therapies can be designed. This is studied in heart muscle, where the clinical gain would ultimately be to be able to prolong the period during a threatened myocardial infarction where permanent injury can be prevented.

7. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies
Abstract : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. READ MORE

8. Studies on mitochondrial adenosine triphosphatase : uncoupler-reversible inhibition of mitochondrial ATPase and related enzymes by metal chelates of bathophenenthroline
Abstract : The mitochondrial ATPase constitutes the terminal enzyme of oxidative phosphorylation and is, together with similar enzymes present in chloroplasts and bacteria, responsible for the synthesis of ATP from ADP and Pi during electron transport. The enzyme consists of an extrinsic, catalytically active part, called Fl, that is structurally and functionally linked to an intrinsic, proton-translocating device, called Fo. READ MORE

9. Analgetic and algetic effects of adenosine in healthy volunteers and patients with coronary disease
Abstract : Background: Adenosine is a bimodal neuromodulator with algesic and analgesic effects. The different effects of adenosine are partly due to the route of administration. Low-dose adenosine infusion induces analgesia at the same magnitude as morphine, while adenosine as bolus injection induces chest pain, similar in character as angina pectoris. READ MORE

10. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress
Abstract : Diabetic nephropathy is the main cause for initiation of renal replacement therapy and early symptoms in patients include increased glomerular filtration rate (GFR), decreased oxygen tension and albuminuria, followed by a progressive decline in GFR and loss of kidney function. Experimental models of diabetes display increased GFR, decreased tissue oxygenation and nitric oxide bioavailability. READ MORE
