  1. 01AnimalAnimal study (in vivo)Activity measurement

    The entire DSIP molecule increased the threshold continuous arousal pattern (TCAP), the indicator of DSIP activity.

    In plain wordsIn an animal arousal test, the whole DSIP molecule increased the arousal measure.

    Summary
    It was found that the entire DSIP molecule increased TCAP
    1 context sentence
    Summary · context
    The experiments were carried out with the entire DSIP molecule and its three different fragments. The method of threshold continuous arousal pattern (TCAP) monitoring was used as the indicator of DSIP activity.

Studies that did not test the peptide alone2

In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Delta sleep-inducing peptide (DSIP).

    The DSIP 1-5 fragment decreased the threshold continuous arousal pattern (TCAP).

    In plain wordsIn an animal arousal test, a small piece of DSIP (fragment 1-5) lowered the arousal measure.
