Use of plasma norepinephrine for evaluation of sympathetic neuronal function in man.
TL;DR: Levels of norepinephrine in human plasma have been determined by a radioenzymatic technique sufficiently sensitive to measure 0.014 ng NE per ml plasma by evaluating sympathetic neuronal function based on the increments in plasma NE produced by postural change and a standard amount of exertion.

TL;DR: Given that the majority of the biological and human health variables remained stable, or returned to baseline, after a 340-day space mission, these data suggest that human health can be mostly sustained over this duration of spaceflight.
Journal ArticleDOI
Noradrenergic projections to the spinal cord of the rat
TL;DR: It was concluded that pontine noradrenergic cell groups are the sole source of noradRenergic terminals in the spinal cord.
Journal ArticleDOI
Plasma noradrenaline increases with age.
TL;DR: Extending the study to teenage and elderly subjects revealed that basal levels of plasma NA correlate with age and that the increase in plasma NA in response to stress is similarly related to age.
Journal ArticleDOI
The Sympathetic-Nervous-System Defect in Primary Orthostatic Hypotension
TL;DR: Findings are consistent with other pathological and pharmacologic observations suggesting that patients with central-nervous-system disease are unable to activate appropriately an otherwise intact sympathetic nervous system, whereas in patients without signs of central-Nervous -system disease the deficit affects peripheral sympathetic nerves.
