  1. 1. Cognitive Deficits Reflecting Diffuse and Focal Brain Lesions Caused by Slow Growing Brain Tumors - Low-grade Gliomas

    Författare :Lena Ek; Ove Almkvist; Anja Smits; Hans Samuelsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognition; low-grade glioma; brain tumor; diffuse brain injury; neuropsychological tests; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The overall purpose was to characterize the impact that low-grade glioma (LGG) – a type of slowly growing brain tumor – has on cognitive functions. Paper I was an in-depth analysis of cognitive dysfunction of patients with histological proven LGG. LÄS MER

  3. 2. Mechanisms of Brain Damage Following Focal Cerebral Ischemia: Changes in Ion Homeostasis and the Importance of Free Radical Formation

    Författare :Gunilla Gidö; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PBN; free radicals; potassium; extracellular calcium; neuronal damage; energy-depletion; hypoglycemia; Cerebral focal ischemia; spreading depression; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : In this thesis mechanisms of neuronal damage were investigated in an experimental stroke model i.e focal ischemia. The influence of SD-induced calcium transients on neuronal damage were studied in animals with reduced energy supply. LÄS MER

  4. 3. Experimental Stroke and Neurotrophins: Regulation, function and gene transfer of neurotrophins in rat and mouse models of focal cerebral ischemia

    Författare :Gunnar Andsberg; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; animal behaviour; striatum; stereology; immunohistochemistry; focal cerebral ischemia; nerve growth factors; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Stroke caused by focal cerebral ischemia is a major cause of death and neurological disability in humans. The forebrain region most commonly affected by ischemic incidents is that supplied by the middle cerebral artery. LÄS MER

  5. 4. Experimental vitreoretinal surgery in the rabbit eye - electrophysiology and morphology

    Författare :Karin Gjörloff; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; retinectomy; GFAP; PKC; rabbit; vitrectomy; focal laser photocoagulation; full-field electroretinography; multifocal electroretinography;

    Sammanfattning : The field of vitreoretinal surgery has expanded greatly over the last decades. A continuous refinement of surgical methods and instruments has increased the number of treatable retinal disorders. Vitrectomy, retinectomy and laser treatment are all part of the modern surgical arsenal. LÄS MER

  7. 5. Brain-derived neurotrophic factor in cerebral ischemia: a quantitative study on surviving and newly formed neurons

    Författare :Elin Gustafsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-derived neurotrophic factor; cerebral ischemia; neuronal survival; neurogenesis; hippocampus; striatum; immunocytochemistry; stereology; neuropsykologi; Neurologi; neurophysiology; neuropsychology; neurofysiologi; Neurology;

    Sammanfattning : This study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.
