Background: Some cancers have high levels of proteins called somatostatin receptors (SSTRs) on the surface of the tumors. These tumors can be in the lung, head and neck, digestive tract, kidneys, and in or near the adrenal glands. Researchers want to know if drug treatments that target SSTRs can help shrink these types of tumors. Objective: To test a study drug ([212Pb]VMT-Alpha-NET) in people with tumors that have SSTRs. Eligibility: People aged 18 years and older with tumors of the lung, kidneys, head and neck, digestive tract, or adrenal glands that have SSTRs. Their tumors must have spread to other organs and cannot be removed with surgery. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and a test of their heart function. A sample of tumor tissue may be collected if one is not already available. [212Pb]VMT-Alpha-NET is given through a tube attached to a needle inserted into a vein. The drug will be given on the first day of four 8-week cycles. Participants will stay in the hospital for a few nights after each dose. They will have blood tests once a week during each cycle. Some participants will also get a related study drug ([203Pb]VMT-Alpha-NET). They will receive this drug a few days before the first 2 cycles. At 4, 24, and 48 hours after each infusion, they will have whole body scans. These scans will show where the study drug went in their body. Follow-up visits will continue up to 6 years after the last treatment.

Background: People with substance use disorder (SUD) often have changes in brain function that can make it difficult to control drug-seeking behavior. These changes may heighten the urge to use drugs or lessen the desire to seek nondrug-related rewards. Researchers want to know how a technique called transcranial magnetic stimulation (TMS) may cause changes in brain activity that may help people with SUD. Objective: To test TMS in healthy volunteers. Eligibility: Healthy people aged 18 to 45 years who are right-handed. Design: Participants can volunteer for up to 5 different experiments. Each experiment requires 2 to 8 clinic visits. Each visit will last 3 to 7 hours. Some visits will include TMS. A coil will be placed on the participant s head. A brief electrical current will pass through the coil to create a magnetic field. Participants may feel a tapping or pulling sensation on the skin under the coil. They may feel a twitch in their face, neck, arm, or leg muscles. Participants may be asked to tense certain muscles during TMS. Some visits will include functional magnetic resonance imaging (fMRI) scans. Participants will lie on a bed that slides into a large tube. They will perform tasks on a computer inside the tube. The fMRI will show which parts of the brain are used during each task. Participants will perform tasks on a computer. Some tasks may be done at a desk as well as during TMS and fMRI. Participants may look at images, listen to sounds, smell odors, or taste flavored liquids. Their vital signs may be monitored and their eye movements may be tracked during tasks.

This study will evaluate and gather information in patients with genetic causes of too much androgen (male-like hormone) in order to better understand the effects of too much androgen and describe problems associated with it. Too much androgen in childhood, if untreated, results in rapid growth and early puberty with early cessation of growth and short stature in adulthood. Too much androgen in adulthood may result in infertility, and women may have excess facial hair, acne and a more male-like appearance. Excess androgen may also affect mood and behavior and possibly the secretion of other hormones, such as insulin. Two genetic diseases that result in early childhood androgen excess are congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP). Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11- hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency and males with known or suspected FMPP may be eligible for this study. Patients with both classic and non-classic CAH are eligible, and patients with androgen excess of unknown cause may be eligible. Participants undergo the following procedures: - Medical history and physical examination. - Fasting blood tests for analysis of hormones, blood chemistries including blood sugar and cardiovascular risk factors such as lipids. - Oral glucose tolerance test for patients with elevated insulin levels. For this test, a catheter (plastic tube) is placed in a vein in the patient's arm. The patient drinks a sugar-containing fluid and blood samples are collected through the catheter at intervals starting with drinking the solution, and then 30, 60 and 120 minutes after drinking the solution. - 24-hour urine collection to measure hormone levels in the urine. - DNA testing for patients with 21-hydroxylase deficiency to help identify the type of genetic mutation responsible for the disease. - X-ray of the left hand to measure bone age in growing children. The x-ray is used to determine how far into puberty the child is and how much growth potential is left in the bones. - A pelvic ultrasound in females and testicular ultrasound in males to evaluate the size and development of the gonads (ovaries in females and testes in males). - Cognitive and psychological tests, including an IQ test and evaluation of memory, achievement and behavior. - Other tests and evaluations based on medical need. The schedule for these procedures varies. In a part of the study involving only patients with CAH, growing children are evaluated twice (once in childhood and once after reaching adult height), and adults are evaluated once. In another part of the study involving patients with CAH and FMPP, growing children are seen twice a year, and adults and children who have reached adult height may be seen annually. Additional visits may be scheduled if medically indicated. In this part of the study, females are asked to keep a record of their periods after their first menstrual cycle.

Adults with Down syndrome (Ds) are often thought to have a lower risk of heart and blood vessel disease because they tend to have lower blood pressure and fewer heart attacks than people without Ds. However, recent research suggests that heart and blood vessel diseases, including stroke, are becoming a more common cause of death in adults with Ds as life expectancy increases. Despite these findings, studies examining heart and blood vessel health in adults with Ds have produced mixed results, making it difficult to determine their true risk and whether preventive strategies are needed. This study will investigate the health of blood vessels in adults with Ds and compare the results with those of adults without Ds. Healthy blood vessels are important because they help deliver blood and oxygen throughout the body. Changes in blood vessel function and stiffness can occur with aging and may increase the risk of heart disease, stroke, kidney disease, and memory problems. The study aims to determine whether adults with Ds experience changes in blood vessel health that may place them at increased cardiovascular risk. Specifically, the study will: (1) Examine how well blood vessels function in adults with Ds; (2) Measure the stiffness of arteries in adults with Ds; (3) Compare two methods used to assess blood vessel function to determine whether a simpler exercise-based test provides results similar to a commonly used standard test. The findings may improve understanding of cardiovascular risk in adults with Ds and help guide future strategies to promote healthy aging in this population.

For this study, the study medicine has been specially prepared to contain radiolabeled carbon [14C]. [14C] is a naturally occurring radioactive form of the element carbon. Adding a low dose of radiation to the study medicine does not change how the medicine works but helps to see how the medicine appears in the blood, urine, and stool after it is given. This type of study is called a radiolabeled study. The purpose of this radiolabeled study is to learn how a certain amount of [14C] PF-07799544 is taken up into the bloodstream and removed from the body. The study is seeking participants who are: Male Ages 18 to 55 years of age confirmed to be healthy based on medical and physical tests. Weigh more than 50 kilograms (kg) and have a body mass index of 17.5 to 32 kg per meter squared. The study consists of two parts. In part one, all participants will receive one full dose of [14C]PF-07799544 by mouth. Part two will begin at least 14 days after the dose in part one. In part two, participants will receive one full dose of PF-07799544 by mouth and one small dose of [14C] PF-07799544 by intravenous (IV) infusion. IV infusion will be directly injected into the veins. To understand how the medicine is processed in the body, samples of blood, urine, feces, and vomit (if any) will be collected after each dose is given. This will help understand: How much PF-07799544 is taken up into the bloodstream when taken by mouth compared to the dose given by IV How the body removes it from the blood steam. Participants will take part in the study for about 7 weeks, including evaluation at the start and follow-up period.
