Cost-consequence analysis of F-fluciclovine for the staging of recurrent prostate cancer.

: Current detection methodologies are often unable to identify the location and extent of recurrent prostate cancer (PCa) leading potentially to 'futile' local therapies in the presence of metastatic disease. The use of  F-fluciclovine PET/CT may lead to better patient management. : The aim of this study was to quantify the economic impact and cost-consequence of using  F-fluciclovine PET/CT in PCa recurrence.

The behavioural response of anaerobic Rhodobacter sphaeroides to temporal stimuli.

The behavioural response of Rhodobacter sphaeroides to temporal changes in the concentration of chemoeffectors, and to stimuli affecting electron transport, was analysed using tethered cells. Populations of photosynthetically grown tethered cells of R. sphaeroides showed a transient response, a stop followed by adaptation, to a stepwise reduction in the concentration of chemoattractants (such as organic acids or sugars) and terminal electron acceptors.
