  2. 1. The Apparent Arbitrariness of Second-Order Probability Distributions

    Author : David Sundgren; Love Ekenberg; Mats Danielson; Lev Utkin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Adequate representation of imprecise probabilities is a crucial and non-trivial problem in decision analysis. Second-order probability distributions is the model for imprecise probabilities whose merits are discussed in this thesis. READ MORE

  4. 2. Transplantation of mesenchymal stem cells and injections of microRNA as therapeutics for nervous system repair

    Author : Mallappa K. Kolar; Lev N. Novikov; Paul J. Kingham; Mikael Wiberg; Elisabet Åkesson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spinal cord injury; peripheral nerve injury; mesenchymal stem cells; regeneration; neurotrophic factor; angiogenic factor;

    Abstract : Traumatic injuries to the spinal cord (SCI) and peripheral nerve (PNI) affect several thousand people worldwide every year. At present, there is no effective treatment for SCI and despite continuous improvements in microsurgical reconstructive techniques for PNI, many patients are still left with permanent, devastating neurological dysfunction.

  5. 3. Schwann cells and mesenchymal stem cells as promoter of peripheral nerve regeneration

    Author : Maria Cristina Mantovani; Mikael Wiberg; Giorgio Terenghi; Susan Shawcross; Lev Novikov; Liudmila Novikova; John W Haycock; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve regeneration; Schwann cell; adult stem cell; myelin; senescence;

    Abstract : The transplantation of primary Schwann cells (SC) has been shown to improve nerve regeneration. However, to monitor the survival of transplanted cells within the host, a stable labelling method is required. READ MORE

  6. 4. Neuroprotection and axonal regeneration after peripheral nerve injury

    Author : Dag Welin; Lev N. Novikov; Lars B. Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dorsal root ganglion; Motoneuron; Axonal reaction; Peripheral nerve injury; Nerve regeneration; N-acetylcysteine; Hand surgery; Handkirurgi; Anatomy; Anatomi; anatomi; Human Anatomy; handkirurgi; hand surgery;

    Abstract : Following microsurgical reconstruction of injured peripheral nerves, severed axons are able to undergo spontaneous regeneration. However, the functional result is always unsatisfactory with poor sensory recovery and reduced motor function. READ MORE

  7. 5. Biosynthetic conduits and cell transplantation for neural repair

    Author : Jonas Pettersson; Lev Novikov; Liudmila Novikova; Mikael Wiberg; Lars Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spinal cord injury; Peripheral nerve injury; Nerve graft; Biosynthetic conduit; Nerve tissue engineering; Neural prosthesis; Neuroscience; Neurovetenskap; neurologi; Neurology; neurokirurgi; Neurosurgery;

    Abstract : Spinal cord injury results in complete failure of the central neurons to regenerate and is associated with cyst formation and enlargement of the trauma zone. In contrast to the spinal cord, axons in the injured peripheral nerve have the capacity to undergo some spontaneous regeneration. READ MORE
