Abstract

Objective Recently cortisol level in hair is supposed to be a good biomarker of chronic stress. We had developed a new method based on HPLC-FLU for identification of cortisol in human hair and measured cortisol distribution of each 1-cm segment along hair shaft.Design and methods Hair sample was pulverized and incubated in 0.1 M HCl and extracted with ethyl acetate. The extraction was derived with sulfuric acid. The derivative was extracted with SPE C18 column.Results The detection limit was 1 pg/mg, the intraday and interday precisions were 7.3% and 8.5%, and average recovery was 102.5+/-13.0%. Cortisol concentrations of 32 humans' hair ranged from 3.28 to 24.83 pg/mg. There was a distinct decline in the cortisol of 1-cm segment along hair shaft.Conclusions This method showed that the precision was matched with mass spectroscopy. The cortisol in 1-cm hair segment sensitively reflects a retrospective calendar over 1 month.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Three independent published samples report cortisol decline rates per 1-cm hair segment of 2.5 pg/mg, 2.7±0.3 pg/mg, and 2.9±0.6 pg/mg.

    “Three independent, published samples report cortisol decline rates per 1-cm hair segment of 2.5 pg/mg (Kirschbaum et al., 2009), 2.7±0.3 pg/mg (Gao et al., 2010), and 2.9±0.6 pg/mg (Xie et al., 2011).”

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.
