Definity, echo contrast, induced cardiac arrest: brief review of the literature.

Definity is a contrast media used to enhance the endocardium during echocardiography. Cardiac arrest as an adverse reaction to Definity is still a debate. We are presenting a rare case of a 69-year-old male patient who developed cardiopulmonary arrest immediately after Definity injection during resting echocardiography.

Genome Sequences of sp. Strain MIT S9220 and Cocultured Cyanophage SynMITS9220M01.

bacteria are unicellular cyanobacteria that contribute significantly to global marine primary production. We report the nearly complete genome sequence of sp. strain MIT S9220, which lacks the nitrate utilization genes present in most marine genomes.
