Understand Diseases and Signs of Aging

Genetic and Epigenetic Signatures of Translational Aging Laboratory Testing (GESTALT)

Background: - Biomarkers are substances in people s blood and tissues. They help researchers understand diseases and signs of aging. Scientists want to do more research on biomarkers to find ways to improve quality of life in old age. Objective: - To learn more about biomarkers and their relationship to aging. Eligibility: - Adults at least 20 years old who weigh at least 110 pounds and have a body mass index below 30. They must agree that their genetic samples can be collected, studied, and stored. Design: - Participants will be screened with medical history, physical exam, and blood and urine tests. They will have heart tests and nurse will assess their veins. They will fill out a questionnaire. - Participants will have a 2-day baseline visit. Then they will return every 2 years for up to 10 years. These follow-up visits will repeat the baseline visit: - Repeat of screening procedures. - Physical performance tests like balance and walking tests. - Leg and grip strength tests. - Health and mental state questions. - Memory and problem solving tests. - Cytapheresis. Blood will be removed through a needle in the vein of one arm and run through a machine. The blood will be returned through a needle in a vein of the other arm. - Visits may also include: - Magnetic resonance imaging scans. Participants will lie on a table that slides in and out of a machine that takes pictures. - Diabetes test. After fasting, participants will drink a sweet drink and give blood. - Breathing and walking tests. - Wearing a device that record physical activity. - Scan of the abdomen and the right leg. - A small amount of muscle tissue and/or skin removed.
