  2. 21. Positron emission tomography studies of the D1-dopamine receptor in schizophrenia

    Author : Per Stenkrona; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis is based on investigations of central D1-dopamine receptor (D1R) binding in vivo using positron emission tomography (PET). The aims were i) to examine the antipsychotic effect of a D1R antagonist in schizophrenia and ii) to test the dopamine hypothesis of schizophrenia by comparing D1R binding between patients and healthy subjects.

  4. 22. Optimisation of radiographic imaging by means of factorial experiments

    Author : Eva Norrman; Jan Persliden; Andreas Oberstedt; Bertil Axelsson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Fysik; Physics;

    Abstract : In the optimisation process of radiographic imaging, factorial designed experiments can be applied. The parameters (factors) are varied together instead of one at a time, making it possible to discover interactions between the factors as well as main influences of them on the result variable.

  5. 23. Studies on Polarised Light Spectroscopy

    Author : Max Bergkvist; Simon Farnebo; Erik Tesselaar; Folke Sjöberg; Johan Thorfinn; Knut Kvernebo; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. READ MORE

  6. 24. Aspects of inflammation and nitric oxide in cluster headache

    Author : Anna Steinberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Cluster Headache;

    Abstract : Cluster Headache (CH) is an uncommon headache disorder, with severe implications for the individual patient. The headache is excruciating, unilateral and appearing in attacks. It is common that CH patients show ipsilateral associated symptoms, like for example conjunctival injection, lacrimation and nasal congestion. READ MORE

  7. 25. Magnetic resonance imaging and diffusion tensor imaging after brachial plexus injury and repair : Experimental and clinical study

    Author : Grainne Bourke; Mikael Wiberg; Lev N. Novikov; Lars Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brachial Plexus; Magnetic Resonance Imaging; Neonatal; Diffusion Tensor Imaging;

    Abstract : Brachial plexus injuries (BPI) cause permanent upper limb paralysis and serious disability in adults and children. Timely identification of the severity of nerve injury and early appreciation of the inane potential for recovery would revolutionise management. READ MORE
