    Keywords : Sleep; polysomnography; coronary disease; surgery; anxiety; psychophysiological disorders; personality; MEDICINE; MEDICIN;

    Abstract : In this thesis sleep, psychological symptoms and quality of life (Qol) in patients undergoing coronary artery bypass grafting (CABG) at the University Hospital in Linköping were evaluated. Interviews and 24-hour polysomnography were performed prior to surgery, immediately after surgery and again at one month, with a six-month-follow-up mailed questionnaire. READ MORE

  3. 3. Morphologican and functional studies on the Drosophila neuromuscular system during postembryonic stages

    Author : Ana Beramendi; Rafael Cantera; Prof. Carlos Dotti; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; neuromuscular system; Rel-proteins; fly brain; rhythmic morphology; aging; ; Neurobiology; Neurobiologi;

    Abstract : The nervous system of the fruit fly Drosophila melanogaster has emerged as an excellent model for fundamental neuroscience as well as for biomedical research of human neurological diseases. In this thesis, two aspects of the neuromuscular system have been investigated: the role of the IkB-protein Cactus in the larval neuromuscular junction and the morphology of motor terminals throughout adult life.

  4. 4. Studies on ventilatory function in chronic neuromuscular disorders

    Author : Jan Weinberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ventilatory dysfunction; neuromuscular disorders; diaphragm; electromyogram; power spectrum; blood gas; ventilatory mechanics; sleep; polysomnography;

    Abstract : Ventilatory dysfunction is common in neuromuscular disorders (NMD). The present studies aimed at evaluating and developing methods for diagnosis of ventilatory function in NMD. Methods included were diaphragmatic EMG (EMGdi), blood gas monitoring assessed at rest and during exercise and nocturnal respiratory and sleep parameters. READ MORE

  5. 5. Rapid neural processing of grammatical tone in second language learners

    Author : Sabine Gosselke Berthelsen; Allmän språkvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; grammatical tone; phonology; phonetics; word accent; morphology; inflection; grammar; EEG; ERP; processing; violations; ELAN; LAN; P600; second language acquisition; SLA; beginner learners; transfer; German; Swedish;

    Abstract : The present dissertation investigates how beginner learners process grammatical tone in a second language and whether their processing is influenced by phonological transfer. Paper I focuses on the acquisition of Swedish grammatical tone by beginner learners from a non-tonal language, German. READ MORE
