  1. 1. Studies of native and Cd(II)-substituted carbonic anhydrases with special reference to their interaction with inhibitors

    Author : Lena Tibell; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Carbonic anhydrase; Cd II ; 113-Cd II -NMR; inhibition; catalytic mechanism;

    Abstract : The major aim of this work has been to gain further insights into the catalytic mechanism of carbonic anhydrase (carbonate hydro-lyase, EC 4.2.1.1). READ MORE

  2. 2. Protein Engineering of Extracellular Superoxide Dismutase : Characterization of Binding to Heparin and Cellular Surfaces

    Author : Ing-Marie Ahl; Lena Tibell; Bengt-Harald Jonsson; Steen Vang Petersen; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : 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. READ MORE

  3. 3. Development of competence in biochemical experimental work : Assessment of complex learning at university level

    Author : Christina Bergendahl; Lena Tibell; Lisbeth Lundahl; Lars-Owe Dahlgren; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teaching; experimental work; laboratory based project work; open experiments; biochemistry; life science; university level; action research; course design; aims and objectives; assessment; formative assessment; competence; complex learning; Didaktik; Subject didactics; Ämnesdidaktik; biokemi; Biochemistry;

    Abstract : 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. READ MORE

  4. 4. Touching the Essence of Life : Haptic Virtual Proteins for Learning

    Author : Petter Bivall; Anders Ynnerman; Lena A. E. Tibell; Matthew D. Cooper; Miriam Reiner; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Haptics; Educational Research; Biomolecular Education; Life Science; JND; Just Noticeable Difference; Protein-ligand Docking; Haptic docking; Visualization; Haptic Transfer Functions; Volume Data Haptics; History Dependent Transfer Function; Log file analysis; Molecular Recognition; Force Feedback; Virtual Reality; Other information technology; Övrig informationsteknik;

    Abstract : 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.

  5. 5. Evolving germs – Antibiotic resistance and natural selection in education and public communication

    Author : Gustav Bohlin; Lena A. E. Tibell; Gunnar Höst; Jörg Zabel; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; natural selection; antibiotic resistance; visualizations; content analysis; threshold concepts; scientific literacy; media analysis;

    Abstract : Bacterial resistance to antibiotics threatens modern healthcare on a global scale. Several actors in society, including the general public, must become more involved if this development is to be countered. The conveyance of relevant information provided through education and media reports is therefore of high concern. READ MORE
