question:
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.
answer:
yes

question:
Question: Is time point important for effects of syngeneic bone marrow transplantation for type 1 diabetes in mice?
Answer: These results indicated that syn-BMT should be performed, when diabetes is neither too new-onset nor too late-stage. Tregs represent one mechanism for syn-BMT-induced restoration of immune tolerance in STZ-diabetic mice.
answer:
yes

question:
Question: Do central adenosine A1 and A2A receptors mediate the antinociceptive effects of neuropeptide S in the mouse formalin test?
Answer: The above findings suggest that: (i) NPS evokes central antinociceptive effects by activating both A1 and A2A receptors during phase 1, but (ii) only the adenosine A2A receptor during phase 2 of the formalin test.
answer:
yes
