Blunted norepinephrine responsiveness to changing energy states in obese subjects

Bazelmans, J., Nestel, P.J., O'Dea, K., Esler, M.D.·1985·Metabolism

Abstract

We have previously reported in lean subjects a significant relationship between plasma norepinephrine metabolism and energy state. The present study has examined in six obese men the response in plasma norepinephrine flux to ten day periods of overeating (+ 1000 kcal/m2 above isocaloric requirements) or undereating (400 kcal/d). Despite significant gains or losses in body weight, norepinephrine flux, measured during constant infusions of 3H-l-norepinephrine, failed to change significantly. Measurements of glucose utilization during constant infusions of insulin, showed significant changes with changing energy state, falling with overeating and rising with undereating. Insulin sensitivity was not correlated with plasma norepinephrine metabolism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
