  1. 16. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

    Författare :Silver Jõemetsa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; supported lipid bilayer; lipophilic dyes; size determination; diffusion; microfluidics;

    Sammanfattning : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. LÄS MER

  3. 17. Hepatic lipase and dolichol esterification

    Författare :Pavel J Sindelar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dolichol is one of the mevalonate pathway end products, present in all tissues and cellular membranes. The lipid is a primary alcohol consisting of 16-23 isoprenoid residues and occurs as a free alcohol, monophosphate or fatty acyl ester. LÄS MER

  4. 18. 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

  5. 19. Fluorescence-based methods to probe long-lived transient states for biomolecular studies

    Författare :Heike Hevekerl; Jerker Widengren; Martin Hof; KTH; []
    Nyckelord :Fysik; Physics;

    Sammanfattning : Fluorescence spectroscopy and imaging are wide-spread tools in life science. Themain read-out parameters are still fluorescence intensity and wavelength, but given thebenefits of multi-parameter characterization there are also good reasons to consideradditional fluorescence-based read-out parameters.

  7. 20. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces

    Författare :Katsuya Fuchino; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coiled coil protein; Streptomyces coelicolor; polar growth; osmotic-stress response; turgor;

    Sammanfattning : Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. LÄS MER
