An expelled or delivered fetus that exhibits no heartbeat, spontaneous respiratory activity, spontaneous movement of voluntary muscles, or pulsation of the umbilical cord (if still attached).

Giving subjects previously undisclosed information about the research project following completion of their participation in research.
