  2. 21. Cerebral oedema after reperfusion therapy in patients with ischaemic stroke : predictors, outcomes and treatment

    Author : Magnus Thorén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Introduction: Reperfusion therapy by intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT) are established treatments in ischaemic stroke. Cerebral oedema (COED), caused by dysfunction the blood brain barrier (BBB), is common early after acute ischaemic stroke (AIS), can aggravate the symptoms and worsen the prognosis. READ MORE

  4. 22. Neuroprotection and neurogenesis after experimental stroke

    Author : Andreas Arvidsson; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stereology; rat; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; BrdU; immunohistochemistry; in situ hybridization; subventricular zone; striatum; dentate gyrus; neuronal replacement; neuronal survival; Focal cerebral ischemia; glial cell line-derived neurotrophic factor;

    Abstract : 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.

  5. 23. The role of the complement system in arthritis and stroke

    Author : Max Albert Hietala; Göteborgs universitet; []
    Keywords : complement; C3; factor B; transgenic knockout; arthritis; focal cerebral ischemia;

    Abstract : Complement is part of the innate immune system and functions primarily as a first line of defense against invading microorganisms. It is a complex cascade, which can be activated via three pathways: the classical, alternative and mannan-binding lectin pathway. READ MORE

  6. 24. Cerebral blood flow and glucose metabolism in ischemic stroke : multimodal imaging investigations in a clinically relevant rat model

    Author : Fabian Arnberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Ischemic stroke is one of the leading causes of death worldwide. Ischemic stroke is also a major cause of long-term disability with vast socioeconomic results for patients, their relatives and health services. READ MORE

  7. 25. The impact of different techniques used for coronary angiography and percutaneous coronary intervention on the occurrence of procedure-related ischemic cerebral complications

    Author : Juliane Jurga; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Coronary angiography (CA) is the gold standard in diagnosing and determining the treatment of patients with coronary heart disease. Procedure-related neurological complications are rare; 0.1-0.4% for CA and percutaneous coronary intervention (PCI). READ MORE
