  1. 11. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

    Författare :Yu-Hsing Huang; Erik Hollnagel; Pietro Carlo Cacciabue; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. LÄS MER

  3. 13. Using de novo design proteins to explore tyrosine radicals and cation-π interactions

    Författare :Bruce W. Berry; Cecilia Tommos; Anders Hofer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tyrosine; radicals; cation-pi interactions; de novo designed proteins; biochemistry; biophysics; Biochemistry; biokemi;

    Sammanfattning : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials.

  4. 14. A biophysical study of nucleic acid interactions with analogues and drugs

    Författare :Ulrica Sehlstedt; Donald M Crothers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic acids; binding modes; polarised light spectroscopy; linear dichroism; NMR; triple helix; base-pair breathing dynamics; DAPI; porphyrins; quinoxaline derivatives; Biophysics; Biofysik; Biophysics; biofysik;

    Sammanfattning : work presented in this thesis concerns studies on the physicochemical nature of interactions between nucleic acids and small ligands. The outcome of such studies can yield insights at a molecular level into the physiological mechanisms of action of biologically active nucleic-acid binding molecules. LÄS MER

  5. 15. Interactions between nutrition, obesity and the immune system

    Författare :Louise Strandberg; Göteborgs universitet; []
    Nyckelord :obesity; nutrition; infection; polymorphisms; interleukin; fatty acids; fat mass; neutrophils; innate immunity; mortality;

    Sammanfattning : There are several links between body fat and the immune system. For example, mice lacking activity of the pro-inflammatory interleukin-(IL)-1 and IL-6 develop obesity. Conversely, obesity is associated with adipose tissue inflammation and increased risk of infection. LÄS MER
