Dr. Kevin Hall and his team at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) are seeking male volunteers aged 18-65 and female volunteers aged 18-50 for a study on how low-carb (ketogenic) diets, with or without an investigational dietary supplement called Nicotinamide Riboside, impacts energy levels and metabolism during sleep.

Researchers are examining genetic and physical characteristics of the small vessel disease called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy). They are enrolling volunteers to serve as healthy controls. Compensation is provided.

Healthy volunteers 18-60 years old are needed to test an investigational drug that was developed to reduce blood pressure in the lungs. The PAH team from @NHLBI hope that this investigational study drug may be helpful in treating patients with PAH in the future.

This study aims to learn more about how drinking alcohol changes your decision-making. Participants will be asked to consume drinks that might or might not have alcohol, then have magnetic resonance imaging (MRI) scans to look at brain activity while making choices related to risky sexual behavior.

A research study at the National Institutes of Health (NIH) is is investigating how dietary habits affect our intestinal microorganisms by studying the effects of Mediterranean-like unprocessed (CLEAN-MED) diet. Participants will be divided into two groups, depending on their interest in trying out the diet for 4 weeks or maintaining a new healthy diet over months, and will be provided with some foods. Participants will log the food they eat and answer questions about their diet throughtout the study. Food and research supplies and procedures are provided at no cost.
