  1. 6. Dynamics of Biomembranes and Rheological Properties of Living Cells

    Författare :Peter Berntsen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell mechanics; lipid dynamics; cell rheology; biomembranes; water dynamics; relaxations; phospholipids; glass transition;

    Sammanfattning : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. LÄS MER

  3. 7. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization

    Författare :Tatsiana Lobovkina; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular nanotube; shape transition; enzymatic reaction; nanotube knot; self-organization; liposome; lipid nanotube; lipid vesicle; nanotube-vesicle network;

    Sammanfattning : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

  4. 8. Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery

    Författare :Jennifer Gilbert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid nanoparticles; neutron scattering; SAXS; protein encapsulation; nucleic acid delivery; lipid self-assembly;

    Sammanfattning : Encapsulation in self-assembled lipid structures has been shown to increase the stability of large biomolecules, including proteins and nucleic acids (NAs), which has many potential applications in the food and pharmaceutical industries. In order to fully optimise the encapsulation system for a certain application, however, it is important to understand the effect of the encapsulated biomolecule on the lipid structure and vice versa.

  5. 9. Exploring the Interactive Landscape of Lipid Bilayers

    Författare :Christian L. Wennberg; Erik Lindahl; Arnold Maliniak; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Dynamics; lipid bilayer; cholesterol; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; Biological Physics; Biologisk fysik;

    Sammanfattning : One of the most important aspects for all life on this planet is theact to keep their cellular processes in a state where they do notreach equilibrium. One part in the upholding of this imbalanced stateis the barrier between the cells and their surroundings, created bythe cell membrane. LÄS MER

  7. 10. Cardiac lipid storage and metabolism following myocardial ischemia

    Författare :Christina Drevinge; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipid accumulation; Myocardial Ischemia; Lipid droplets; Perilipin2; Perilipin5;

    Sammanfattning : Myocardial ischemia is associated with cellular- and metabolic adjustments within the heart, including accumulation of lipids. Myocardial lipids are stored in cytosolic droplets, consisting of a core of neutral lipids surrounded by a complex surface containing proteins, such as perilipins. LÄS MER
