  2. 16. The Neurological Wake-up Test in Neurocritical Care

    Author : Karin Skoglund; Niklas Marklund; Per Enblad; Tiit Mathiesen; Uppsala universitet; []
    Keywords : Intracranial pressure; Cerebral perfusion pressure; Propofol sedation; Wake-up test; stress hormones; intracerebral microdialysis; brain tissue oxygenation; jugular venous oxygenation; Neurokirurgi; Neurosurgery;

    Abstract : The neurological wake-up test, NWT, is a clinical monitoring tool that can be used to evaluate the level of consciousness in patients with traumatic brain injury (TBI) and subarachnoid haemorrhage (SAH) during neurocritical care (NCC). Since patients with severe TBI or SAH are often treated with mechanical ventilation and sedation, the NWT requires that the continuous sedation is interrupted. READ MORE

  4. 17. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study

    Author : Holger Noack; Margareta R. A. Blomberg; Per E. M. Siegbahn; Martin Kaupp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; Bio-inorganic chemistry; Bio-oorganisk kemi; Theoretical chemistry; Teoretisk kemi; kemisk fysik; Chemical Physics;

    Abstract : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. READ MORE

  5. 18. Tumour vasculature, oxygenation and radiosensitivity - a numerical modelling study

    Author : Jakob Heydorn Lagerlöf; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Dosimetry; Hypoxia; Modelling; Radionuclide therapy; Radiotherapy; Tumour Control Probability;

    Abstract : This thesis aims to investigate theoretically how parameters such as vessel density, blood oxygenation, blood velocity, spatial oxygen variation along vessels, tissue oxygen consumption and their distributions in uence the radiosensitivity of tumours. Numerical calculations are made in Matlab using voxel-based models. READ MORE

  6. 19. Spinal cord oxygenation during thoracic aortic clamping in pigs

    Author : Anders Hellberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Thoracoabdominal aortic replacement; spinal cord ischaemia; cerebrospinal; intrathecal monitoring; oxygen tension; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Despite a dramatic reduction in the mortality associated with thoracoabdominal aorticreplacement during the past 40 years, spinal cord ischaemia that results in paraplegia remainsa serious complication. Simple and reliable intraoperative monitoring techniques are neededto detect impending neurological deficit in time to prevent permanent damage. READ MORE

  7. 20. Aspects of circulatory failure in respiratory extracorporeal membrane oxygenation

    Author : Lars Falk; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Extracorporeal Membrane Oxygenation (ECMO) was developed in the seventies for the intended use of supporting respiratory failure. Today ECMO has become a well-established treatment for patients with both respiratory and circulatory failure where conventional intensive care is inadequate. READ MORE
