Changes in oxygen diffusive conductances of human placentae during gestation (10–41 weeks) are commensurate with the gain in fetal weight

Abstract

Evidence is adduced that the oxygen diffusive conductance of the human placenta increases during gestation. Results are based on placentae from 10 weeks to term. The diffusion pathway is analysed as six discrete tissue compartments arranged in series. Stereological and physicochemical data are used to determine partial, total and specific diffusive conductances for each organ and for its tissue compartments. During gestation, maternal and fetal vascular spaces became more voluminous and exchange surface areas of villi and capillaries expanded. Both were manifestations of placental growth and development. Maturation of villi was evident as decreases in effective diffusion distances across the trophoblast and villous stroma. These alterations contributed to improvements in partial and total conductances which continued towards term. Changes within the trophoblast and stroma were particularly influential in determining total conductance. Those on maternal and fetal sides of the diffusion pathway were less important. The rise in total conductance was related directly to the rise in fetal weight. Specific diffusive conductance was constant throughout gestation.

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

  • The theoretical diffusing capacity for oxygen expressed per kg of fetal weight remains constant across gestational age.

    “It is notable that the theoretical diffusing capacity for oxygen expressed per kg of fetal weight remains constant across gestational age (364, 368), suggesting placental development determines the rate of fetal growth or that the two are closely co-regulated.”

  • The value expressed per kg of fetus remains constant across gestation, suggesting that development of the placenta and fetus are closely interlinked.

    “The fact that the value expressed per kg of fetus remains constant across gestation suggests that development of the placenta and fetus are closely interlinked (368).”

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.
