  1. 16. Volterra Modeling and Estimation of the Human Smooth Pursuit

    Författare :Viktor Bro; Alexander Medvedev; Geoff Chase; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volterra models; Volterra-Laguerre models; Nonlinear modeling; Smooth pursuit; Eye tracking; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. LÄS MER

  3. 17. Volterra modeling of the human smooth pursuit system in health and disease

    Författare :Viktor Bro; Alexander Medvedev; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis treats the identification of Volterra models of the human smooth pursuit system from eye-tracking data. Smooth pursuit movements are gaze movements used in tracking of moving targets and controlled by a complex biological network involving the eyes and brain. LÄS MER

  4. 18. Characterization of HIV-1 in the central nervous system during suppressive therapy

    Författare :Viktor Dahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Combination antiretroviral therapy (cART) is effective in suppressing HIV-1 RNA levels below the lower-limit of detection of clinical assays (.... LÄS MER

  5. 19. Molecular pharmacology of amiodarone

    Författare :Viktor Drvota; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Amiodarone; thyroid hormone receptors; B-adrenergic receptors; AT-1 cardiomyocytes; Western blot; solution hybridization; Fura-2; Langendorff heart; mouse; guinea pig;

    Sammanfattning : Amiodarone (Am) is a potent class III antiarrhythmic drug. Its use is limited due to serious side effects and it was therefore used only when other therapeutic interventions proved to be ineffective. LÄS MER

  7. 20. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Författare :Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    Sammanfattning : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.
