Question: 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.

Answer: no

Question: Question: Does intravenous insulin therapy during lung resection affect lung function or surfactant proteins?
Answer: According to our observations, short insulin treatment applied intravenously during resection does not affect the quality of breathing.

Answer: no

Question: Question: Is cardiovascular reactivity to mental stress affected by alpha2-adrenoreceptor activation or inhibition?
Answer: Cardiovascular reactivity to mental stress is not related to pharmacologically manipulated tonic central sympathetic nervous system activity by alpha2-adrenergic agonists and antagonists. These results do not support the assumption that cardiovascular reactivity is an index of tonic central sympathetic nervous system activity.

Answer:
no
