  1. 6. NMR studies on interactions between the amyloid β peptide and selected molecules

    Författare :Anna Wahlström; Astrid Gräslund; Göran Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amyloid β peptide; Alzheimer s disease; Aggregation; Oligomer; Amyloid; Interaction; Nuclear Magnetic Resonance Spectroscopy; Circular Dichroism Spectroscopy; Thioflavin T; Detergent; Congo red; Affibody; Cyclodextrin dimer; Metal ion; Chemistry; Kemi; Biochemistry; Biokemi; Biophysics; biofysik;

    Sammanfattning : Alzheimer’s disease is an incurable neurodegenerative disorder linked to the amyloid β (Aβ) peptide, a 38-43 residue peptide. The detailed molecular disease mechanism(s) is (are) unknown, but oligomeric Aβ structures are proposed to be involved. LÄS MER

  3. 7. The molecular chaperone CCT: Functions beyond folding

    Författare :Josefine Vallin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TRiC; Chaperonin; CCT oligomer; CCT monomer; cancer; p150Glued; gelsolin; STAT3;

    Sammanfattning : The chaperonin-containing tailless complex polypeptide 1 (CCT) is a eukaryotic ~1 MDa barrel shaped molecular chaperone, built up by eight distinct subunits and is required for the folding of the abundant cytoskeletal proteins actin and tubulin. CCT exists as an assembled oligomer, micro-complexes and as individual subunits in the cell. LÄS MER

  4. 8. The Extended Role of the Molecular Chaperone CCT

    Författare :Andreas Svanström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CCT oligomer; Actin; CCT delta; CCT epsilon; Gelsolin; MRTF-A; Cell morphology;

    Sammanfattning : The oligomeric chaperone CCT is a large ATP-dependent chaperonin that consists of two rings placed back-to-back with eight different paralogous subunits with a size of ~ 55 kDa that sit in each of the two rings. The function of CCT is mainly to fold the abundant proteins actin and tubulin, components of the cytoskeleton. LÄS MER

  5. 9. Plasticized Poly (lactic acid) Films - Preparation and Properties

    Författare :Nadia Ljungberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase separation; aging; thermal properties; dynamic mechanical properties; processing; film preparation; oligomer synthesis; poly lactic acid ; plasticizers; migration; cold crystallization; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : The development of biodegradable polymers from renewable resources is of importance in order to prevent the depletion of fossil fuels and the increasing emissions of carbon dioxide to the atmosphere caused by the commodity plastics of today. However, to be able to replace these non-environmentally friendly materials, production costs of biodegradable polymers have to be decreased and their physical properties need to be enhanced.

  7. 10. Influence of Bridge Structures on the Electron Transfer in Donor-Acceptor Systems

    Författare :Mikael Winters; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular wire; electron transfer; porphyrin; conjugated oligomer;

    Sammanfattning : In this Thesis, porphyrin-based donor-acceptor systems have been used to study photoinduced electron transfer processes. Principally, two different sets of systems have been investigated. LÄS MER
