  1. 41. Immunological and Inflammtory Responses against Intrastriatal Neural Grafts in the Rat

    Författare :Wei-Ming Duan; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; MHC; Rat; Brain; Xenogeneic; Allogeneic; Syngeneic; Cytokine; Inflammation; Neural transplantation; Immunology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Intracerebral neural transplantation offers a new strategy to combat Parkinson’s and Huntington’s diseases. However, a host immune response against a histoincompatible neural graft in the brain may jeopardize transplant survival. LÄS MER

  3. 42. Death mechanisms compromising hippocampal neurogenesis after status epilepticus

    Författare :Christine Ekdahl Clementson; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; minocycline; lipopolysaccharide; microglia activation; status epilepticus; epilepsy; cysteinyl aspartate-specific proteases; apoptosis; neurogenesis; progenitor cell progeny;

    Sammanfattning : Status epilepticus (SE) leads to neurodegeneration as well as neurogenesis in the adult rat hippocampus. This thesis demonstrates that even if the neurogenic response initially is very pronounced, with a several-fold increase in cell proliferation, the survival of the newly formed neurons is compromised by a death mechanism involving mitochondria-related caspases.

  4. 43. Detection and haemodilutive treatment of cerebral arterial vasospasm and delayed ischaemia after Aneurysmal Subarachnoid Haemorrhage

    Författare :Anders Ekelund; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. LÄS MER

  5. 44. Severe Head Injury. Evaluation of Acute Treatment and Rehabilitation

    Författare :Christer Eker; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; cerebral blood flow; neuropsychological test; assessment of motor and process skills; rehabilitation; Neurology; neuropsychology; neurophysiology; intracranial pressure; Severe head injury; intensive care;

    Sammanfattning : Mortality after severe head injury can be considerably reduce with a therapy using physiological principles for brain volume regulation and preserved microcirculation, with the main purpose of restricting the rise in ICP to reasonable levels simultaneously with preservation of adequate blood supply. This study shows that the ?Lund Concept? can reduce mortality in patients with severe traumatic brain lesions from 47% to 8%. LÄS MER

  7. 45. Aspects of Frontal and Medial Temporal Brain Functions : Neuropsychological and functional imaging studies in normals and in frontotemporal dementia

    Författare :Christina Elfgren; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neurophysiology; regional cerebral blood flow; Neuropsychological assessment; frontotemporal dementia; normal subjects; frontal lobes; medial temporal lobes; neuropsychology; Neurology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The thesis is based on five investigations. In the first study the nature and the degree of cognitive impairment of patients with frontotemporal dementia (FTD) is explored. The results from neuropsychological assessment are described as three levels of cognitive impairment. LÄS MER
