Do you have cardiovascular disease risk factors? Do you sit too much? Help researchers learn more about the most effective strategy for interrupting sitting! If you are 45 years or older, you may be able to take part in a research study to find out if interrupting sitting with walking or pedaling reduces cardiovascular disease risk.

Nutrition is not one-size-fits-all. Nutrition, or the foods we eat, can help prevent and fight conditions such as high blood pressure, diabetes, stroke, and more. However, we all live in different environments, we come from different cultures, and each of us is starting from a different place with our health. Additionally, everyone breaks down food differently. Join the Nutrition for Precision Health research study to help researchers learn how our genes, cultural backgrounds, and environments affect our bodies' responses to food. Compensation provided.

We are looking for women between the ages of 18-45 to join a national health study to help us understand the impact of HIV on women's lives and bodies. Both women living with HIV and women without HIV are invited to take part.

We are looking for people who are between the ages of 30-70 to join a national health study to help us better understand the impact of chronic health conditions on people living with HIV. Both people living with HIV and people without HIV are invited to take part.

During puberty, adolescents grow and change a lot which may make life seem more stressful and emotional. Male and female adolescents experience the changes associated with puberty differently, possibly because of different responses to changes in hormones, including testosterone and estrogen. We are interested in learning more about the role of these hormones in regulating emotional processing and mood symptoms, and whether a mobile training program can help improve mood during the pubertal transition. Participation is 8 weeks with two monthly follow-up surveys. Compensation provided.

The current propellant in some inhalers is known to have a relatively high global warming potential (GWP) compared to CO2. In this study, AstraZeneca is evaluating a potential alternative propellant, which has a much lower GWP. This study is being conducted to evaluate if a new propellant (the HFO) used in inhalers has a negative effect on the way the lungs clear mucus, when compared to the current inhaler propellant (the HFA)." Please note that AstraZeneca is not responsible for the privacy policy of any third party websites, including this one.

We want to learn how people's brains adapt when responding to various food stimuli and decision-making processes. We also want to learn about brain responses to food and beverage consumption. To do this, we will use taste tests, surveys, behavioral tasks, and neuroimaging (fMRI scan).

The purpose of this research study is to get feedback from Black and Latino (a/e/x) participants on the SMILE mHealth app, an app developed to monitor the effects of a mindfulness program through heart rate monitoring and questionnaires.

Leveraging our decades of experience studying the acute and chronic effects of traumatic brain injury (TBI) and concussion, our investigative team propose an innovative, translational approach that bridges both preclinical and clinical studies. We propose testing multiple potential preventative and therapeutic strategies in the preclinical setting, while simultaneously conducting a prospective, longitudinal study of neurologic health outcomes associated with concussion and sub-concussive exposure in former NFL players. Our prior studies of former NFL players over the past 15 years provide us with a unique opportunity to conduct a truly prospective, longitudinal study of long-term neurologic health outcomes and determine any possible association with concussion and repetitive sub-concussive exposure. In parallel, we have developed animal models of repeated concussions (repetitive mild TBI [rmTBI]) and chronic traumatic encephalopathy (CTE). We have studied the effects of readily translatable preventative and therapeutic strategies, including the N-methyl-D-aspartate (NMDA) receptor antagonist memantine, low dose carbon monoxide

In this study, we want to learn more about the experiences and activities of high school-aged youth after a neurological event. This study will also help us to understand the perspectives of youth and a parent/caregiver through photos and stories.
