  1. 1. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER

  3. 2. Development of Surface-Based Methods for Studies of Non-Electrolyte Membrane Transport

    Författare :Seyed Tabaei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane junction; surface plasmon resonance; membrane transfer; supported lipid bilayer; quartz crystal microbalance; aquaporin; bicelles; fluorescence microscopy;

    Sammanfattning : Membrane-transport proteins are a diverse family of proteins that all span the cell membrane where they control the transfer of nutrients, metabolites and ions into and out of the cell. Due to their vital role for the function of cells, reliable methods, preferably with high-throughput capacity, to study this class of proteins are essential in fundamental studies as well as in discovery and development of new drugs.

  4. 3. The Human Spiral Ganglion

    Författare :Sven Tylstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. LÄS MER

  5. 4. Towards Better Understanding of Etiological Mechanisms at the Neuromuscular Junction

    Författare :Evgenii Bogatikov; Anna Rostedt Punga; Klas Kullander; Viktorija Kenina; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuromuscular junction; Muscle cells; Microelectrode array; MicroRNA; Clinical Neurophysiology; Klinisk neurofysiologi; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : The neuromuscular junction (NMJ) serves as a model for understanding the mechanisms that determine communication between neurons and their target cells. Disorders of the NMJ can be either autoimmune or genetic (hereditary). LÄS MER

  7. 5. Middle ear structure in relation to function : the rat in middle ear research

    Författare :Nils Albiin; Umeå universitet; []
    Nyckelord :rats; Eustachian tube; ear; middle; tympanic membrane; palatal muscles; mucous membrane; blood vessels; mast cells; otitis media; microscopy; electron;

    Sammanfattning : The present study was undertaken to evaluate the rat as a model for middle ear re­search. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. LÄS MER
