The goal is to address the mechanisms that account for alteration of circadian rhythms with age. As the blood of aged individuals can produce this alteration, we propose to use such blood samples to "age" circadian rhythms in cultured cells. We will verify aged blood-dependent alteration of rhythms and then conduct molecular screens to reverse this decline. If we identify specific genes that can restore molecular circadian rhythm in vitro, we will explore these in animal models (Drosophila, mouse).

This study sought to assess the effect of a community-based intervention influencing adherence status at baseline, 1, 3 and 6 months, and to evaluate the impact that a community-based intervention an...
Observational Study
A work that reports on the results of a clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
Controlled Before-after Studies
A study in which observations are made before and after an intervention, both in a group that receives the intervention and in a control group that does not.
Early Intervention (education)
Procedures and programs that facilitate the development or skill acquisition in infants and young children who have disabilities, who are at risk for developing disabilities, or who are gifted. It includes programs that are designed to prevent handicapping conditions in infants and young children and family-centered programs designed to affect the functioning of infants and children with special needs. (From Journal of Early Intervention, Editorial, 1989, vol. 13, no. 1, p. 3; A Discursive Dictionary of Health Care, prepared for the U.S. House of Representatives Committee on Interstate and Foreign Commerce, 1976)
Interrupted Time Series Analysis
A study that uses observations at multiple time points before and after an intervention (the "interruption"), in an attempt to detect whether the intervention has had an effect significantly greater than any underlying trend over time.
Historically Controlled Study
A study that compares a group of participants receiving an intervention with a similar group from the past who did not.
