  1. 1. Mechanisms of Ischemic Brain Injury- studies in murine hippocampal slice cultures

    Författare :Anna Rytter; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neuropsychology; Neurology; adenosine; caspases; hypothermia; in vitro; hippocampus; ischemia; neurofysiologi;

    Sammanfattning : Cerebral ischemia is a major cause of mortality and morbidity in the western world. Even though much effort has been put into research and development of effective drugs against ischemic damage there is to date no effective pharmacological brain protective treatment. LÄS MER

  3. 2. Experimental porcine models of retinal ischemia

    Författare :Håkan Morén; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal ischemia; animal model; multifocal electroretinography; intraarterial coiling; retinal vasculature;

    Sammanfattning : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. LÄS MER

  4. 3. Ischemic Tolerance and Cell Signaling in the Rat Brain

    Författare :Mehrdad Shamloo; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preconditioning; cell death; tyrosine phosphorylation; tolerance; ERK; Calpain; CaMKII; PKC; protection; Brain; ischemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : A brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. LÄS MER

  5. 4. Changes in gene expression during delayed neuronal death after cerebral ischemia in the rat

    Författare :Fredrik Kamme; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; ischemia; brain; neuronal death; gene expression; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : After transient global cerebral ischemia, selected populations of neurons in the brain will die after a period of 2-3 days, a phenomenon termed delayed neuronal death. This is of clinical importance as delayed neuronal death has been found to occur in humans as well. LÄS MER

  7. 5. Intestinal Ischemia and Reperfusion Injury - Pathophysiology as basis for novel treatment

    Författare :Zhengwu Sun; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; organ dysfunction; epithelium; endothelium; adhesion molecules; cytokines; protease inhibitor; Intestine; barrier; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Intestinal ischemia and reperfusion (I/R) is not infrequent in the clinical situation and the intestinal barrier plays an important role in gut barrier function, preventing not at least septic complications and potentially the development of the multiple organ dysfunction syndrome. Mechanisms of intestinal I/R induced gut epithelial and endothelial barrier dysfunction and remote organ dysfunction, as well as potential preventive and therapeutic modes of management were evaluated in the rat.
