    Sammanfattning : The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. LÄS MER

  3. 12. Intracranial Pressure in Traumatic Brain Injury

    Författare :Sima Shahsavari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

    Sammanfattning : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. LÄS MER

  7. 15. Pharmacokinetics and Pharmacodynamics of Oxycodone and Morphine with Emphasis on Blood-Brain Barrier Transport

    Författare :Emma Boström; Margareta Hammarlund-Udenaes; Ulrika Simonsson; Danny D Shen; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; pharmacokinetics; pharamcodynamics; blood-brain barrier; oxycodone; microdialysis; NONMEM; brain distribution; transport; Farmakokinetik Farmakoterapi;

    Sammanfattning : The pharmacokinetics and pharmacodynamics of oxycodone and morphine was investigated and related to the transport across the blood-brain barrier (BBB) in rats. The influence of a P-glycoprotein (P-gp) inhibitor on the plasma pharmacokinetics and pharmacodynamics of oxycodone was evaluated. LÄS MER
