Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In organotypic suprachiasmatic nucleus slices of neonatal common voles, none of the slices showed a circadian modulation of VIP release.

    In plain wordsIn vole brain clock tissue in the lab, the body's own VIP release showed no daily rhythm in any slice.

    Summary · context
    In this study we measured neuropeptidergic release patterns in organotypic SCN cultures of neonatal common voles (Microtus arvalis, n = 6).
    Summary · context
    After 14 days of incubation, 2 h samples of medium were collected during 50 h.

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.
