Sammanfattning : Cytochrome cd1 nitrite reductase is a bifunctional enzyme, which catalyses the one-electron reduction of nitrite to nitric oxide, and the four-electron reduction of oxygen to water. The latter is a cytochrome oxidase reaction. Both reactions occur on the d1 haem iron of the enzyme. LÄS MER
3. Involvement of Heparan Sulphate Biosynthesis and Turnover in Cell Proliferation. A Novel Role for Nitric Oxide in Recycling of Heparan Sulphate Proteoglycans
Sammanfattning : The present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. LÄS MER
Sammanfattning : Pulmonary hypertension (PH) is a pathophysiological state associated with several medical conditions, leading to progressive rise in pulmonary vascular resistance (PVR) and right ventricular failure. The clinical PH classification encompasses five main World Health Organization (WHO) groups; pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxia, chronic thromboembolic PH, and PH with unclear multifactorial mechanisms.

Sammanfattning : The focus of the thesis is on selection and adaptation processes in bacteria with emphasis on denitrifying bacteria in groundwater. Other nitrogen transformation processes such as dissimilatory nitrate reduction to ammonium (nitrate ammonification) and nitrification of forest soil bacteria are briefly discussed. LÄS MER
