The current study tests whether different exposures to carbon dioxide (CO2) can safely result in the increased movement of proteins from the brain into the blood. The investigators believe that this would be a proxy for the brain clearing waste products more effectively. The current study will use a counter-balanced design, in which individuals with and without a history of traumatic brain injury (TBI) will receive different levels of CO2 (targeted changes of approximately 5 or 10 mmHG in end-tidal CO2) approximately one week apart. The counter-balanced design means that each participant receives a single dose of CO2 at each visit, and different doses of CO2 at each visit. The order in which participants receive the dose is randomized, and the participant will not be informed of the dose.

The purpose of this study is to test the impact of a multilevel decision support intervention on informed decisions about breast MRI among high-risk Black and Latina women. Participants (N=80) will be randomized to (1) enhanced usual care (risk assessment + referral to nurse practitioner) or (2) decision support (enhanced usual care + decision aid). Assessments will take place at baseline (T0) and 1-month post-intervention (T1). The primary outcome is informed decisions about breast MRI at T1.

The research study is being conducted to better understand the effects of ketones and alcohol on brain functioning and brain metabolism. Participants will be asked to undergo three identical MRI visits after three single-dose interventions: (1) drink a ketone supplement drink, (2) drink an alcoholic beverage, (3) no intervention. These interventions will be randomly assigned (meaning everyone receives all 3 interventions, but in different orders).

The proposed research is to determine the clinical efficacy and neurobiological mechanisms of acupuncture analgesia in patients with sickle cell disease.

Brain blood flow will be measured during a simulated postural change test and while breathing increased levels of carbon dioxide using magnetic resonance imaging.

Brain blood flow will be measured during exercise using magnetic resonance imaging.

The research study is being conducted in health controls to better understand the effects of ketosis on brain functioning after 3 different, randomly assigned, 3-day dietary interventions and the acute effects of alcohol after consuming about 4-5 alcohol beverages. The labs visits will use magnetic resonance imaging (MRI) scans to study the brain, measuring levels of nicotinamide adenine dinucleotide (NAD), lactate, neurotransmitters glutamate, and Gamma-aminobutyric acid (GABA).

The goal of this clinical trial is to evaluate whether early integration of palliative care in the care of hospitalized patients with advanced liver disease (AdvLD) can improve patients' quality of life, physical symptoms, mood, and serious illness communication. Palliative care is a medical specialty focused on lessening (or "palliating") symptoms and assisting in coping with serious illness.

This trial tests a new laser treatment for men aged 50-80 with certain types of prostate cancer. The laser heats and destroys cancer cells, guided by advanced imaging to protect healthy tissue. The goal is to reduce side effects like impotence and incontinence seen with traditional treatments. Recently, there has been an increase in research and development of targeted prostate cancer treatments due to the high number of localized prostate cancers.

To determine whether using bpMRI in subjects who are at high risk of developing prostate cancer in conjunction with PSA will improve prostate cancer screening protocols.

The proposed clinical trial would evaluate the use of smartphone applications ("apps", which have well-established efficacy in reducing cigarette and alcohol use) to prevent relapse among patients receiving medication-assisted treatment for opioid use disorder. In addition to standard app-based self-monitoring of drug use and personalized feedback, project innovation is enhanced by the proposed use of location-tracking technology for targeted, personalized intervention when participants enter self-identified areas of high risk for relapse. Furthermore, the proposed sub-study would use longitudinal functional neuroimaging to elucidate the brain-cognition relationships underlying individual differences in treatment outcomes, offering broad significance for understanding and enhancing the efficacy of this and other app-based interventions.

This research study is evaluating a program that entails a healthcare at home intervention for people with advanced liver disease.
