[EX Q]: Question: Does pEEP ventilation cause humorally mediated cardiac output depression in pigs?
Answer: As humorally mediated negative inotropism during PEEP ventilation has earlier been demonstrated in dogs, the results suggest that this mechanism might be species-dependent.
[EX A]: no

[EX Q]: Question: Does eHD3-dependent endosome pathway regulate cardiac membrane excitability and physiology?
Answer: These data provide new insight into the critical role of endosome-based pathways in membrane protein targeting and cardiac physiology. EHD3 is a critical component of protein trafficking in heart and is essential for the proper membrane targeting of select cellular proteins that maintain excitability.
[EX A]: yes
