  1. 1. Cell activation and nerve regeneration following peripheral nerve injury

    Författare :Annika Widerberg; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; nerve regeneration; Nerve injury; conditioning lesion; nerve graft; tourniquet compression; vibration; DRG; Schwann cell; p75; CPON; neurofysiologi; neuropsykologi; Neurologi; neurophysiology; neuropsychology;

    Sammanfattning : The effect of short time vibration exposure and tourniquet compression on nerve regeneration in rats was studied with special reference to cell activation. One of the hindlimbs was conditioned by either vibration exposure (5 hours / day - 5 consecutive days) or compression (150-300 mmHg for 30-120 minutes), which was followed by a recovery period of 0-7 days.

  3. 2. Development of biosynthetic conduits for peripheral nerve repair

    Författare :Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

    Sammanfattning : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.

  4. 3. Genetic Mechanisms during Terminal Cell Fate Specification in the Drosophila CNS

    Författare :Johannes Stratmann; Stefan Thor; Jan-Ingvar Jönsson; Christos Samakovlis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Specification of the many unique neuronal subtypes found in the nervous system depends on spatiotemporal cues and terminal selector cascades, mostly acting in sequential combinatorial codes of transcription factors (TFs) to dictate cell fate. Out of 10,000 cells in the Drosophila embryonic ventral nerve cord (VNC), only 28 cells selectively express Nplp1. LÄS MER

  5. 4. Peripheral nerve reconstruction. Studies on cellular and acellular iso-, allo- and xenografts

    Författare :Martin Kvist; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acellular nerve graft; costimulation blockade; FK506; immunosuppression; nerve graft; nerve defect; nerve regeneration; nerve injury; nerve extraction; allograft; xenograft;

    Sammanfattning : The best results after a nerve injury with a defect are achieved by a nerve reconstruction procedure using autologous nerve grafts. However, limitations include insufficient amount of suitable donor material and donor site morbidity. The aim of the present thesis was to study alternative nerve grafts, i.e. LÄS MER

  7. 5. The Actin Filament System : Its Involvement in Cell Migration and Neurotransmitter Release

    Författare :Anna-Karin Johnsson; Roger Karlsson; Stéphane Gasman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Actin; Profilin; Synaptotagmin; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Sammanfattning : The microfilament system consists of actin filaments as the major component and is regulated by a number of actin binding proteins. It is juxtaposed to the plasma membrane where it forms a dense cortical weave from where it pervades into the cell interior. LÄS MER
