    Författare :Joakim Wigström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; amperometry; QCM-D; micro electrode array; large dense core vesicles; chromaffin cells; PC-12 cells; microelectrode; exocytosis; electrochemical cytometry; electrochemical imaging; acetylcholine; endocytosis; nanoparticles; enzyme biosensor; microfabrication;

    Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER

  3. 2. Towards a Translational Pain Model - Techniques and developments

    Författare :Leila Etemadi; Neuronano Research Center (NRC); []
    Nyckelord :UVB irradiation; Pain; Neuropeptides; Inflammation; Contralateral; Lateral spinal nucleus; Micro-array electrodes; Pan-neuronal markers; immunohistochemistry;

    Sammanfattning : Pain is a major health issue for each affected individual and has a large impact on health costs. Most of our knowledge about this defensive system rely on data from different animal experiments. There is an obvious need for a translational pain model allowing comparisons between experimental animals and humans. LÄS MER

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

    Författare :Evgenii Bogatikov; Anna Rostedt Punga; Klas Kullander; Viktorija Kenina; Uppsala universitet; []
