| Study Title | A pilot study of urine metabolomics in two female and one male subject towards an outpatient estimate of circadian phase using urine storage as a factor (part II) |
| Study Summary | Serial urine samples were collected at each void (approximately every 3 hours) from subjects during a 6-day inpatient protocol. The total volume of each sample was measured, and then 5 mL was aliquoted into a 7 mL tube and elivered on ice to the processing lab, where the samples were then stored at either -20 degrees or -80 degrees (see details below). At the end of the study, samples were transported (~2 blocks) from the processing lab to our -20 or -80 freezer for storage. The samples being sent represent samples from two female subjects (3634A and 3635A) and one male subject (3624A). These subjects all spent 6 days in the lab: 3 baseline days where the subjects slept for 8 hours at night (at habitual times as determined during the screening period) and 16 hours of ambulatory wake in ambient light, followed by 50 hours of continuous wakefulness in which the subject was kept in a semi-recumbent position in bed under dim light and fed hourly isocaloric snacks (called a constant routine). We are requesting untargeted profiling of samples from these subjects (plus 6-sulphatoxymelatonin profile) to determine how the concentrations of different metabolites vary across the 24-hour period, and specifically to compare this circadian variation in each metabolite during a 48-hour ambulatory period versus a 48-hour constant routine period. |
