[EX Q]: Question: Does implementing goal-directed protocols reduce length of stay after cardiac surgery?
Answer: A milestone-driven pathway supported by team rounding was associated with decreased lengths of CVICU and hospital stay. However, tracking patient trajectories by milestones suggests a more complex relationship than anticipated and presents new opportunities for SREBP implementation and research.
[EX A]: yes

[EX Q]: Question: Does discovery-based protein expression profiling identify distinct subgroups and pathways in leiomyosarcomas?
Answer: These results suggest that UPS tumors share a similar lineage as leiomyosarcomas and are likely to originate from different stages of differentiation from mesenchymal stem cells to smooth muscle cells.
[EX A]: yes

[EX Q]: Question: Are tissue factor expression and activity increased in peripheral monocytes isolated from uncomplicated hypertensive patients?
Answer: We demonstrated that TF mRNA and activity levels in monocytes obtained from uncomplicated hypertensive individuals are comparable with those of normotensive subjects, whereas atherosclerotic hypertensive patients showed increased levels of these parameters.
[EX A]:
no
