A panel of Trypanosoma brucei strains tagged with blue and red-shifted luciferases for bioluminescent imaging in murine infection models.

Background: Genetic engineering with luciferase reporter genes allows monitoring Trypanosoma brucei (T.b.) infections in mice by in vivo bioluminescence imaging (BLI).

Spin echo BOLD fMRI on songbirds.

The advent of high-field MRI systems has allowed implementation of BOLD fMRI on small animals. Increased magnetic field improves the signal-to-noise ratio and thus allows improvement of spatial resolution. However, it also increases susceptibility artefacts in the commonly acquired gradient echo images.
