Abstract

This article describes the calibration of a histochemical method to determine the myoglobin concentration in individual cardiomyocytes. Calibration is based on paired microdensitometric determinations in sections stained for myoglobin and on biochemical myoglobin determinations in tissue samples from different hearts. In addition, the staining intensity of sections from gelatin blocks containing known amounts of myoglobin is determined. To construct a calibration line, sections stained for myoglobin must be corrected for the degree of shrinkage caused by glutaraldehyde fixation and biochemical myoglobin determinations must be corrected for interstitial space. As an example, the method is used to determine the myoglobin concentration in individual skeletal muscle fibers and in control and hypertrophied rat cardiomyocytes. The amount of myoglobin per cardiomyocyte nucleus is increased two- to threefold in hypertrophied cardiomyocytes, whereas changes in myoglobin concentration depend on the model of hypertrophy used.

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.
