  1. 1. Visually guided swimming in box jellyfish: A study of swimming behaviour in response to visual stimuli

    Författare :Ronald Petie; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vision; steering; swimming; behaviour; box jellyfish; Cubozoa; Tripedalia cystophora; biomechanics;

    Sammanfattning : Most animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. LÄS MER

  5. 4. Swimming with the current : Fictive locomotion reveals subtle phenotypes in the zebrafish locomotor network

    Författare :Harmen Kornelis Koning; Henrik Boije; David McLean; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dmrt3a; wt1a; spinal cord; Mauthner cell; neural development; locomotor network; zebrafish;

    Sammanfattning : Neural networks are the functional building blocks of the central nervous system. To better understand how these networks develop and operate, we turned to the zebrafish locomotor network, with a focus on subtypes of interneurons expressing dmrt3a and wt1a. LÄS MER

  7. 5. 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.
