Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • In humans, 40 IU of intranasal vasopressin increased CSF levels from about 5 pg/ml to about 10 pg/ml within 10 minutes and to about 20 pg/ml at 60 minutes.

    “Born et al. reported that, after giving 40IU (80µg) in man, CSF levels rose within 10min from ~5pg/ml to ~10pg/ml, increasing to ~20pg/ml at 60min (17).”

    From Intranasal Oxytocin: Myths and Delusions (2016) · cites this paper as [17]

  • Born et al. achieved plasma vasopressin of 20 pg/ml after 40 IU intranasal, higher than Robertson et al. reported for any patient, including those with pathologically elevated vasopressin; maximal urine concentrating ability in humans occurs at about 5 pg/ml.

    “Born et al. achieved plasma concentrations of 20pg/ml after giving 40IU vasopressin (17).These are higher than Robertson et al. reported for any patient, including those with pathologically elevated vasopressin secretion; in man, maximal urine concentrating ability is achieved at a vasopressin concentration of ~5pg/ml (33).”

    From Intranasal Oxytocin: Myths and Delusions (2016) · cites this paper as [17]

  • In Born et al.'s study, approximately 4.5 ng of vasopressin reached the CSF, representing 0.005% of the administered dose, if the rise came from the administered peptide rather than indirect endogenous release.

    “Estimating the CSF volume as 300ml, it seems that ~4.5ng of vasopressin reached the CSF: 0.005% of the given dose -assuming that the rise was due to administered peptide and not endogenous release triggered indirectly.”

    From Intranasal Oxytocin: Myths and Delusions (2016) · cites this paper as [17]

  • Neuropeptides gain access to the brain following intranasal administration.

    “neuropeptides have been shown to gain access to the brain following intranasal administration (Born et al., 2002;Chang et al., 2012).”
  • Using nasal delivery, substantial amounts of insulin are delivered into the brain.

    “Using this delivery route, substantial amounts of insulin are delivered into the brain5”

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.
