Brief, Irregular Oscillations of Basal Plasma Insulin and Glucose Concentrations in Diabetic Man

Lang, D A, Matthews, D R, Burnett, M, Turner, R C·1981·Diabetes

Abstract

The basal plasma insulin and glucose concentrations of 12 diet-treated maturity-onset diabetics were measured at minute intervals for 2 h. Brief, irregular oscillations (mean period 8.8 min) in plasma insulin were superimposed on longer term fluctuations (> 30 min). Time series analysis demonstrated a synchronous plasma glucose oscillation (mean amplitude 0.03 mmol/L) associated with short insulin cycles. The glucose changes seen in diabetic subjects were similar to the short plasma insulin cycles (< 10 min) observed in normal subjects. In contrast, the longer plasma insulin cycles (> 10 min) of normal subjects were associated with a plasma glucose oscillation that rose before the end of the cycle. The demonstration of insulin oscillations independent of preceding plasma glucose changes in both normal and diabetic subjects suggests a pancreatic oscillating mechanism or “pacemaker.” The associated glucose changes may reflect the entrainment, by the insulin cycles, of glucose production or utilization.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Elevation of plasma glucose by intravenous glucose infusion triggers oscillations in plasma insulin with a period of ~10 min.

    “When blood samples are taken at high frequency (every min), it becomes clear that elevation of plasma glucose (by intravenous glucose infusion) triggers oscillations in plasma insulin with a period of ~10 min (363) (Figure 15C).”

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.
