  1. 11. High-resolution imaging of kidney tissue samples

    Författare :David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Sammanfattning : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  3. 12. High-resolution phenotypic profiling of a eukaryotic ribosome

    Författare :Jonathan Esguerra; Göteborgs universitet; []
    Nyckelord :ribosome; ribosomal protein genes; box C D snoRNA; box H ACA snoRNA; 2’-O-ribose methylation; pseudouridylation; high-resolution phenotypic profiling; chemogenetic profiling; Saccharomyces cerevisiae; rRNA modification;

    Sammanfattning : All living cells contain ribosomes, complex macromolecular assemblies of ribonucleic acid (RNA) and proteins, responsible for synthesizing polypeptides in a process called translation. High-resolution three-dimensional ribosomal structures coupled with biochemical studies have paved the way in understanding the various mechanistic events during protein synthesis. LÄS MER

  4. 13. High-resolution biomedical phase-contrast tomography

    Författare :William Twengström; Hans Hertz; Anna Burvall; Marco Stampanoni; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Fysik; Physics;

    Sammanfattning : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. LÄS MER

  5. 14. Surface Plasmon Resonance : Sensitivity and Resolution

    Författare :Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. LÄS MER

  7. 15. Combining low resolution, high resolution, functional, and simulation techniques : In the study of pentameric ligand-gated ion channels

    Författare :Marie Lycksell; Erik Lindahl; Kresten Lindorff-Larsen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrons; Small-angle scattering; Cryo-EM; Simulations; Ion channels; Biophysics; biofysik;

    Sammanfattning : Combining methods yielding different information is a powerful approach for understanding structural biology in general, and in particular systems such as pentameric ligand-gated ion channels (pLGICs). Pentameric ligand-gated ion channels are membrane proteins that sense chemical signals, which they convert to changes in membrane potential. LÄS MER
