  1. 21. Experimental magnetic resonance imaging modalities as tools to evaluate brain function, structure and networks : exercise and cocaine induced adaptations

    Författare :Adam Sierakowiak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Psychiatric disease is common, costly and globally spread. Currently there are few efficient treatments that help patients to be remitted to a high degree. There is a need for improvement of robust objective diagnostic markers that can help the physicians to diagnose, follow-up or monitor treatment schedules. LÄS MER

  3. 22. Infants hospitalised with acute respiratory tract infections. Mapping, description, and evaluation of physiotherapy treatment methods including frequent changes in body position and stimulation of physical activity

    Författare :Sonja Andersson Marforio; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical therapy modalities; respiratory tract infections; bronchiolitis; pneumonia; infants; randomized controlled trial;

    Sammanfattning : The overall aim of this thesis was to increase knowledge about physiotherapy treatment for infants with lower respiratory tract infections, which is the most common reason for infant hospitalisation worldwide. Physiotherapy treatment for these infants is debated, and there is no clear consensus regarding the best treatment strategy. LÄS MER

  4. 23. Neuroimaging Consciousness: What happens in the brain when we become aware of what we percieve?

    Författare :Johan Eriksson; Lars Nyberg; Martin Ingvar; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Although consciousness has been studied since the beginning of the history of psychology, how the brain implements consciousness is seen as one of the last great mysteries. This thesis investigates neural correlates of consciousness by measuring brain activity while specific contents of consciousness are defined and maintained. LÄS MER

  5. 24. Improving the therapeutic ratio of stereotactic radiosurgery and radiotherapy

    Författare :Bahram Andisheh; Bengt Lind; John Hopewell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; stereotactic radiosurgery; stereotactic radiotherapy; radiobiology; modeling; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : New methods of high dose delivery, such as intensity modulated radiation therapy (IMRT), stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), hadron therapy, tomotherapy, etc., all make use of a few large fractions. LÄS MER

  7. 25. Ultrasound Contrast Agents Loaded with Magnetic Nanoparticles : Acoustic and Mechanical Characterization

    Författare :VeeraVenkata Satyanarayana Kothapalli; Lars-Åke Brodin; Jan Engvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound contrast agents; SPION nanoparticles; harmonic oscillation; backscattering power; attenuation coefficient; phase velocity; nonlinear equation of motion;

    Sammanfattning : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. LÄS MER
