Example Input: Question: Does unloading of baroreceptors by carotid occlusion increase heart rate in fetal sheep?
Answer: We conclude that in contrast to adult animals, in fetal sheep carotid occlusion with subsequent unloading of baroreceptors does not increase heart rate even when the baroreflex had been activated by arterial hypertension. It seems likely that stimulation of carotid chemoreceptors prevents the expected baroreceptor mediated heart-rate response.
Example Output: no
