Does subjective sleepiness predict objective sleep propensity?
In controlled laboratory conditions, high correlations between subjective and objective measures of sleepiness within subjects were found across a large range of sleepiness (20:00 to 01:30) for all conditions. Calculating correlations within subjects and across a range of the circadian variation in sleepiness contributed substantially to the strength of the relationship found. These results suggest that the variability of prior research findings may be due, at least partly, to the way in which correlations were derived.
The novel RF device efficiently delivered macromolecules into the skin while reserving SC layers to support some barrier functions. In this work, for the first time the assistance of fractional RF on peptide and siRNA transport was demonstrated.
