1. 36. Neuroprotection and neurogenesis after experimental stroke

   Författare :Andreas Arvidsson; Lund Neurologi; []

   Sammanfattning : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.

3. 37. Multiple Sclerosis: Studies of the Interferon system and search for infectious agents

   Författare :My Bergkvist; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; Axon and myelin damage; IgG; Virus; Interferon; Multiple Sclerosis; Genetic linkage;

   Sammanfattning : Multiple sclerosis (MS) is a chronic disease of the central nervous system, characterized by focal inflammatory lesions with demyelination and axonal loss. It is believed that MS is an immune-mediated disorder with both genetic and environmental contributions to the pathogenesis. LÄS MER

4. 38. Brain plasticity and hand function

   Författare :Anders Björkman; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Kirurgi; ortopedi; traumatology; Surgery; Medicin människa och djur ; Medicine human and vertebrates ; hand function; nerve injury; brain plasticity; orthopaedics;

   Sammanfattning : The aim of this thesis was to investigate the effects of cortical reorganisational changes following experimental deafferentation and peripheral nerve injury and apply the concept of brain plasticity to enhance sensory re-education following peripheral nerve injury and repair in the hand. In the first two papers the effects on hand function of contralateral deafferentation was investigated. LÄS MER

5. 39. Ischemic Cell Death in the CNS - applications of a new in vitro model

   Författare :Tobias Cronberg; Sektion IV; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; Neurology; astrocyte; stroke; adenosine; hyperglycaemia; glucose; free radicals; calcium; in vitro; brain ischemia; slice; neuropsychology; neurofysiologi; neurophysiology;

   Sammanfattning : Ischemic brain damage is a common cause of death and disability. A global ischemic insult is usually the result of a transient cardiac arrest while occlusion of cerebral blood vessels leads to focal ischemic lesions, commonly termed stroke. LÄS MER

7. 40. Neurogenesis and transplantation in stroke-damaged brain

   Författare :Vladimer Darsalia; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neuropsychology; neurophysiology; Neurologi; Neurology; Stroke; Transplantation; Stem cells; Aging; Neurogenesis; neurofysiologi;

   Sammanfattning : Stroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. LÄS MER
