We are doing this study to learn more about the connection between the brain and leg muscles in people who have chronic stroke. We want to understand how this connection affects the walking abilities of chronic stroke patients so we can provide better help to stroke patients who need to improve their motor function.

If you participate, you will be asked to provide a blood draw of about 5.4 mL, or 1/3 tablespoon, of blood. If you are one of the first 20 subjects, you may have the chance to participate in one additional blood draw.

Participants will be in the study for 6 months. Each month, they will provide blood samples, complete surveys, and have energy measurements taken. During months 4 and 5, participants will take part in a short stress activity, such as heat exposure, mild sleep loss, or exercise, for 5 days in a row.

We are doing this study to learn more about how environmental contaminants (e.g., "forever chemicals") can affect people's likelihood of developing liver disease.

The goal of this study is to learn more about how certain hormones and cells in the pancreas help keep blood sugar at a healthy level. This is very important when the body does not respond well to insulin, which can happen with obesity and diabetes. By doing this study, researchers hope to find better ways to care for and treat diabetes.

We are doing this study to determine the impact of smoking electronic cigarettes (e-cigs) on lung health. This will be done by comparing study procedures and imaging results between healthy participants that use e-cigs versus those who don't.

If you are in this study, you will fill out an online survey that takes about 30 to 40 minutes. The study team will also collect basic information about you, such as your age and background, along with results from your colonoscopy. This information will be saved in secure research databases. You can choose to give extra samples if you want. These may include a small blood sample taken before your colonoscopy, a stool sample you collect at home using a kit, and extra tissue from your medical procedure. The study team will also review your health records over time to see how you are doing.
