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

    Author : Annika Widerberg; Malmö Handkirurgi; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Martin Kvist; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Phospholipase A2 in nerve injury and axonal outgrowth

    Author : Marie Hornfelt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neurology; cell death; apoptosis; leukotrienes; arachidonic acid; M-type receptor; secretory phospholipase A2; cytosolic phospholipase A2; sciatic nerve; dorsal root ganglia; growth cone; axonal outgrowth; nerve injury; peripheral nerve regeneration; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with processes coupled to injury in the peripheral nervous system (PNS), with a general aim to investigate the role of phospholipase A2 (PLA2) enzymes in axonal outgrowth. The axonal outgrowth of dorsal root ganglia (DRG) neurons in vitro was reduced by several different inhibitors of PLA2 activity and enhanced by an activator of this enzyme. READ MORE

  4. 4. Sensory neuronal protection & improving regeneration after peripheral nerve injury

    Author : Andrew McKay Hart; Mikael Wiberg; Angus McGrouther; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell death; TUNEL; optical disection; dorsal root ganglion; peripheral nerve; nerve conduit; Schwann cell; glial growth factor; leukaemia inhibitory factor; acetyl-L-carnitine; N-acetyl-cysteine; Neurovetenskap; Neurology; Neurologi; neurokirurgi; Neurosurgery;

    Abstract : Peripheral nerve trauma is a common cause of considerable functional morbidity, and healthcare expenditure. Particularly in the ~15% of injuries unsuitable for primary repair, standard clinical management results in inadequate sensory restitution in the majority of cases, despite the rigorous application of complex microsurgical techniques.

  5. 5. Development of biosynthetic conduits for peripheral nerve repair

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

    Abstract : 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.
