  1. 21. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    Författare :Zhan-You Wang; Göteborgs universitet; []
    Nyckelord :autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Sammanfattning : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

  3. 22. Studies in sporadic inclusion body myositis

    Författare :Snjólaug Arnardóttir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord : s-IBM; muscle fibre regeneration; cytoskeleton; IVIg; muscle inflammtion; cytokine; training; sensibility; neuropathy ;

    Sammanfattning : Aims: The general aims of the present study were to increase the understanding of the disease process in s-lBM by analysing the cytoskeletal structure in muscle fibres and their regeneration potential; and also to evaluate sensory function in patients with s-IBM to test the hypothesis of an associated neurogenic component or a concomitant neuropathy in s-IBM; and to evaluate therapeutic options by analysing the effect of IVIg treatment on the muscle inflammation; and to evaluate the effect of training on muscle function and muscle inflammation. Patients: Twenty-six patients with the diagnosis of s41BM participated in these studies. LÄS MER

  4. 23. Facial nerve injury and microsurgical repair : Experimental and clinical studies

    Författare :Davor Jergovic; Thomas Carlstedt; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Facial palsy is a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. This underlines the need for more effective treatment procedures. LÄS MER

  5. 24. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

    Författare :Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

    Sammanfattning : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. LÄS MER

  7. 25. Cell-matrix interactions in neuronal regeneration : focus on integrins and laminins

    Författare :Stefan Plantman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The central and peripheral nervous system (CNS and PNS, respectively) differ in their ability to regenerate after injury. This difference has been attributed both to intrinsic differences in the properties of the neurons and to the extracellular environment. LÄS MER
