1. Studies of native and Cd(II)-substituted carbonic anhydrases with special reference to their interaction with inhibitors
Sammanfattning : The major aim of this work has been to gain further insights into the catalytic mechanism of carbonic anhydrase (carbonate hydro-lyase, EC 18.104.22.168). LÄS MER
2. Protein Engineering of Extracellular Superoxide Dismutase : Characterization of Binding to Heparin and Cellular Surfaces
Sammanfattning : Accumulating evidence indicates that oxygen free radicals are involved in many diseases and pathological conditions, such as aging, inflammation, reperfusion damage of ischemic tissue and various cardiovascular diseases. Extracellular superoxide dismutase (ECSOD) thus plays a major role in the maintenance of cells by providing protection against these toxic substances in the extracellular space. LÄS MER
Sammanfattning : Barns föreställningar utgör en viktig del i deras begreppsbildning inom naturvetenskap vilket betonas inom konstruktivismen. I denna avhandling utgör en socialkonstruktivistisk syn på lärande det teoretiska ramverket. LÄS MER
4. Development of competence in biochemical experimental work : Assessment of complex learning at university level
Sammanfattning : Biochemistry is part of life science: a fast developing multidisciplinary area. The overall aims of this thesis and the work underlying it were to find ways in which to develop competence in biochemistry at university level and to assess complex learning. A particular interest was the development of experimental work as a means to promote learning. LÄS MER
Sammanfattning : This dissertation presents research in the development and use of a multi-modal visual and haptic virtual model in higher education. The model, named Chemical Force Feedback (CFF), represents molecular recognition through the example of protein-ligand docking, and enables students to simultaneously see and feel representations of the protein and ligand molecules and their force interactions.
