Background: PDE4D is a protein in the body that plays a role in thinking and depression. This protein may play a major role in disorders such as Alzheimer disease or major depressive disorder. To learn more about these disorders, researchers want to be able to detect levels of PDE4D in the brain. 11C-JMJ-129 is a new radiotracer (a radioactive substance that highlights parts of the body during imaging scans) that was developed to attach only to PDE4D. Objective: To test the new radiotracer 11C-JMJ-129 during imaging scans in healthy volunteers. Eligibility: Healthy people aged 18 years and older who had a screening assessment under protocol 01-M-0254. Design: Participants will have 2 to 4 clinic visits. Participants will be screened. They will have a physical exam. They will have blood tests and a test of their heart function. Participants will undergo 1 or more of these scans: A positron emission tomography (PET) scan of the whole body. The radiotracer will be injected through a tube placed in a vein in the arm. Participants will lie on a table while a donut-shaped machine passes over them. Blood will be drawn from the arm during this scan. A magnetic resonance imaging (MRI) scan of the brain. Participants will lie on a table that slides into a tube. A PET scan of the brain. These participants will be injected with the radiotracer. They will lie on a table with their head in the scanner. Participants will be called within 3 days after each PET scan for a check on their health. Read Less

The investigators are interested in finding out how Prolonged Nightly Fasting (PNF) and/or health education may impact health and cancer recovery for breast cancer patients and survivors. Read Less

The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System. Results from this study will be used to guide development and refinement of new software features that may be implemented in future commercial software releases. Read Less

This phase II trial studies how well enteric-coated (EC) aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. EC Aspirin may help to keep the prostate cancer from coming back. Rintatolimod may stimulate the immune system and interfere with the ability of tumor cells to grow and spread. Interferon-alpha 2b may improve the body's natural response to infections and may slow tumor growth. It is not yet known how well rintatolimod, EC aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery. Read Less

The purpose of this study is to determine the efficacy of lidocaine 2.5%/prilocaine 2.5% cream versus lidocaine 23%/tetracaine 7% ointment for topical anesthesia prior to a nonablative laser procedure. Read Less

This trial studies how well 68Ga-PSMA-11 PET scan works in imaging patients with prostate cancer. Diagnostic procedures, such as 68Ga-PSMA-11 PET may find and diagnose prostate cancer and improve monitoring of treatment response. Read Less

This study is open to adults with different types of advanced cancer (solid tumors) that are accessible for injection and/or biopsy. This is a study for people with a life expectancy of at least 3 months after starting study treatment. The purpose of this study is to find the highest dose of a medicine called BI 1831169 that people with advanced cancer can tolerate when taken with or without a type of antibody called a checkpoint inhibitor (anti-PD-1 antibody). Another purpose is to check whether the study treatment can fight cancer. In this study, BI 1831169 is given to people for the first time. This study has 2 parts. In Part 1, participants get BI 1831169 alone for up to 3 months. In Part 2, participants get BI 1831169 in combination with a checkpoint inhibitor. Participants who take the combination treatment get BI 1831169 for up to 3 months and a checkpoint inhibitor for up to 1 year. BI 1831169 is given as an injection into the tumor, or as an infusion into the vein, or both (injection and infusion). Checkpoint inhibitors are given as an infusion into a vein. Participants get the medicines about every 3 weeks. This is called a treatment cycle. Participants visit the site study site regularly. The number of study visits vary based on the study phase and treatment response. Some visits include an overnight stay. The doctors regularly check the participants' health and monitor the tumors. The doctors also take note of any health problems that could have been caused by the study treatment. Read Less

This is a 12-month multi-level behavioral cluster randomized trial testing a church-based intervention to improve physical function (PF) in Americans with PF limitations. Read Less

Children with pulmonary hypertension (PH) engage in less physical activity than their peers. This is a concern since adult data support exercise as a non-pharmacologic treatment for PH. Despite adult data, therapeutic exercise has not been widely adopted in pediatric PH. Investigators have previously demonstrated that children with PH have less skeletal muscle mass in association with worse exercise performance. Interventions to increase physical activity and skeletal muscle mass may improve exercise performance and quality of life in children with PH. This study will use wearable activity monitoring devices to promote physical activity in a 16-week pilot intervention in children and teenager with PH. Read Less

B-cell malignancies are a group of cancers of B lymphocytes, a type of white blood cell responsible for fighting infections. The purpose of this study is to assess safety, tolerability, pharmacokinetics and preliminary efficacy of ABBV-525 as a monotherapy. ABBV-525 is an investigational drug being developed for the treatment of B-Cell Malignancies. Study doctors put the participants in groups called treatment arms. Participants will receive ABBV-525 at different doses. Approximately 100 adult participants will be enrolled in the study across sites worldwide. In part 1 (dose escalation), participants will receive escalating oral doses of ABBV-525. In part 2 (dose optimization), participants will receive one of two oral doses of ABBV-525, until the recommended phase 2 dose (RP2D) is determined. In part 3 (dose expansion), participants will receive the RP2D oral dose of ABBV-525. The estimated duration of the study is up to 64 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and scans. Read Less
