  4. 2. NMR studies on lipid-peptide co-aggregation between ganglioside-containing membranes and α-synuclein

    Author : Simon Fridolf; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein aggregation; nuclear magnetic resonance spectroscopy; lipid membrane; ganglioside; alpha-synuclein;

    Abstract : This topic of this thesis is how the presence of biomembrane molecules affect the behavior of a protein related to Parkinson’s disease in a simplified (compared to in the cell) model system.Lipids are fat molecules that make up the biological barriers in our body that control transport of essential molecules in and out of the cell and create an environment where membrane proteins can perform their functions.

  5. 3. Multiscale simulations of soft matter: systematic structure-based coarse-graining approach

    Author : Alexander Mirzoev; Alexander Lyubartsev; Nico van der Vegt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multiscale modeling; Monte Carlo; Molecular dynamics; ion solution; lipid bilayer; coarse-graining; fysikalisk kemi; Physical Chemistry;

    Abstract : The soft matter field considers a wide class of objects such as liquids, polymers, gels, colloids, liquid crystals and biological macromolecules, which have complex internal structure and conformational flexibility leading to phenomena and properties having multiple spacial and time scales. Existing computer simulation methods are able to cover these scales, but with different resolutions, and ability to link them together performing a multiscale simulation is highly desirable.

  6. 4. Interorganellar connectivity : From protein to lipid homeostasis

    Author : Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

  7. 5. Adsorption and Self-Assembly of Cationic Surfactants at Silica Surfaces

    Author : Cecilia Ström; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Abstract : The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). READ MORE
