1. 1. Stem cell transplantation and regeneration after dorsal root avulsion

   Författare :Carl Trolle; Elena Kozlova; Adam Reid; Uppsala universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regeneration; dorsal root; sensory nerve; nerve injury; cell transplantation; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Spinal root avulsion leads to paralysis and loss of sensory function. Surgical methods can improve motor function and ameliorate pain but sensory recovery in adults is poor. Previous studies have shown that cell transplantation or treatment with trophic factors can improve functional outcome in rodents after dorsal root transection or crush. LÄS MER

3. 2. Stem Cell Transplantation in Dorsal Root Injury

   Författare :Carl Trolle; Elena Kozlova; Niklas Marklund; Karin Nordström; Michael Andäng; Mårten Risling; Uppsala universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sensory Neuron; Regeneration; Spinal Root; Stem Cell; Neuroscience; Neurovetenskap;

   Sammanfattning : After traumatic injuries to the brachial plexus there is a risk that one or more of the spinal roots are torn from the spinal cord, known as avulsion injury. This often leads to paralysis and chronic pain, notoriously difficult to treat with current pharmacotherapy. LÄS MER

4. 3. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots

   Författare :Gunnar Byröd; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Nerve root; dorsal root ganglion; intervertebral disc; nucleus pulposus; epidural space; nerve fibre; permeability; blood flow; sciatica;

   Sammanfattning : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

5. 4. Studies on pain-related messengers and receptors in dorsal root ganglia and spinal cord

   Författare :Malin Rydh-Rinder; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Pain is the most common reason why people seek medical advice. A large group of patients suffering from so-called neuropathic pain, due to injury to the nervous system itself, is often not helped by the currently available therapies. Classical analgesic drugs, such as opioids and non-steroidal anti-inflammatory drugs, may have severe side effects. LÄS MER

7. 5. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

   Författare :Per Gustavsson; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

   Sammanfattning : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. LÄS MER
