  1. 16. Modelling of polarization by molecular force fields: Further development of the NEMO potential

    Författare :Asbjørn Holt; Lunds universitet; []
    Nyckelord :;

    Sammanfattning : Understanding of intermolecular interactions are important in order to gain insight into a large number of physical processes. This thesis concerns itself with theoretical modelling of such interactions. In particular there is a focus one of interaction contributions called polarization. LÄS MER

  3. 17. Apoptosis induced by a human milk protein complex. Cellular and structural studies in tumour cells and bacteria

    Författare :Anders Håkansson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; nuclear uptake; caspases; mitochondria; S. pneumoniae; alpha-lactalbumin; milk; breast-feeding; Apoptosis; tumour cells; transplantation; Immunologi; serologi;

    Sammanfattning : Human milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. LÄS MER

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

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

    Sammanfattning : 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). LÄS MER

  5. 19. NMR Studies of Bacterial Albumin-Binding Modules

    Författare :Maria U Johansson; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

    Sammanfattning : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. LÄS MER

  7. 20. Dissolution Kinetics and Alteration Products of Micas and Epidote in Acidic Solutions at Room Temperature

    Författare :Birgitta Estmark Kalinowski; Per Aagaard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Mineralogy; Petrology and Geochemistry; mineralogi; petrologi och geokemi;

    Sammanfattning : The reaction kinetics of the weathering of several phyllosilicates and one sorosilicate were stud ied experimentally. The alteration products were characterised by various methods in clud ing XRD, HRTEM, SEM, FTIR, NMR and Mössbauer spectroscopy. LÄS MER
