  2. 1. On Brain Oedema

    Author : Mårten Jungner; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; brain oedema; fluid therapy; blood-brain barrier;

    Abstract : Traumatic brain injury and bacterial meningitis may at a glance appear as two different disease entities. The host reaction, however, to both trauma and infection involves a strong inflammatory response, with the classical symptomology of rubor, tumor, calor, dolor et functio laesa. READ MORE

  4. 2. Blood-Brain Barrier Transport : Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies

    Author : Stina Syvänen; Margareta Hammarlund-Udenaes; Mats Bergström; Gunnar Blomquist; Jashvant Unadkat; Uppsala universitet; []
    Keywords : Pharmaceutical biosciences; pharmacokinetics; P-glycoprotein; blood-brain barrier; modelling; PET; active efflux; species differences; [11C]verapamil; drug development; Farmaceutisk biovetenskap;

    Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE

  5. 3. Translational Aspects of Blood-Brain Barrier Transport and Brain Distribution of Drugs in Health and Disease

    Author : Sofia Gustafsson; Margareta Hammarlund-Udenaes; Stina Syvänen; Irena Loryan; Danica Stanimirovic; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Neurovascular unit; Pharmacokinetics; Neurodegenerative disease; Drug transport; Brain tissue binding; Positron emission tomography; Brain regions; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : A high unmet medical need in the area of CNS diseases coincides with high failure rates in CNS drug development. Efficient treatment of CNS disease is constrained by limited entrance of drugs into the brain owing to the blood-brain barrier (BBB), which separates brain from blood. READ MORE

  6. 4. Pathophysiology of blood-brain barrier, brain edema and cell injury following hyperthermia : New role of heat shock protein, nitric oxide and carbon monoxide : an experimental study in rat using light and electron microscopy

    Author : Hari Shanker Sharma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; blood-brain barrier; heat stress; hyperthermia; brain edema; serotonin; nitric oxide; carbon monoxide; heat shock protein; glial fibrillary acidic protein; myelin basic protein; opioids; histamine; catecholamines; naloxone; indomethacin; p-CPA; electron microscopy; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

    Abstract : This thesis deals with the molecular mechanisms of hyperthermia induced brain damage in rats. The results clearly establish that hyperthermia caused by 4 h heat stress at 38° C is associated with a breakdown of the blood-brain barrier (BBB) permeability which seems to be instrumental in causing brain edema and cell injury.

  7. 5. Blood Vessels, Biomarkers, and Broken Barriers: lnvestigations of the Brain Vasculature in Models of Neonatal Brain lnjuries

    Author : E. Axel Andersson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neonatal brain injury; hypoxia ischemia; germinal matrix haemorrhage; blood brain barrier; tight‐junctions; blood vessels;

    Abstract : Brain injury during the perinatal period can lead to lifelong impairment in cognitive and motor function, or an early death. Term neonatal encephalopathy and preterm germinal matrix haemorrhage are two conditions that can irreversibly injure the brain, but clinical tools for diagnosing and treating these pathologies are lacking.
