NCT06351098
To examine the relations between sleep (nap transitions, sleep physiology), memory, and brain development longitudinally, the researchers will assess n=180 children (in order to acquire n=152 usable data sets) who are 36-54 months of age and habitual nappers at enrollment. In each wave, the researchers will assess memory, memory change over a nap and equivalent waking interval, sleep physiology of the nap, and brain structure and function (using Magnetic Resonance Imagining or MRI). Additionally, overnight sleep physiology will be assessed in all participants. Waves will take place approximately every 6 months. For all children, three waves will be collected. With these data, the researchers will address the following aims: * Examine neural markers that predict the sleep transition (Aim 1); * Examine changes in sleep-dependent memory processing (mnemonic discrimination) over both nap and overnight sleep intervals, across the sleep transition (Aim 2); * Examine changes in sleep microstructure in both nap and overnight sleep across the sleep transition (Aim 3) * Examine interrelations among brain, memory and sleep microstructure across the sleep transition (Aim 4)
NCT00976742
The investigators hypothesize that the degree to which older generally healthy but sedentary men and women improve a number of cardiovascular (CV) disease risk factors with 6 months of highly-standardized endurance exercise training will be a function of common genetic variations in candidate genes.
NCT03723928
This randomized research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body. Using markers to prompt when scans should be ordered may be as good as the usual approach to monitoring disease.
