Escherichia coli were genetically modified to enable programmed motility, sensing, and actuation based on the density of features on nearby surfaces. Then, based on calculated feature density, these cells expressed marker proteins to indicate phenotypic response. Specifically, site-specific synthesis of bacterial quorum sensing autoinducer-2 (AI-2) is used(More)
UNLABELLED There have been many studies on the relationship between nonpathogenic bacteria and human epithelial cells; however, the bidirectional effects of the secretomes (secreted substances in which there is no direct bacterium-cell contact) have yet to be fully investigated. In this study, we use a transwell model to explore the transcriptomic effects(More)
Bacteria secrete and recognize communication molecules to coordinate gene expression in a process known as quorum sensing (QS). Through coordinated expression, bacteria are able to influence phenotypic changes on a larger population scale, such as biofilm formation. Recent studies into interkingdom communication have found cross-talk communication among(More)
Despite the fact that all geospatial data are, at different levels, imperfect, GIS technologies do not offer much support to GIS users to make them aware of the imperfections and potential limitations in the use of these data. Recent research progresses have been made towards the design of GIS that would take into account data quality. These approaches(More)
