Featured Studies

Investigators at the National Heart, Lung, and Blood Institute are seeking healthy volunteers, 18-60 years old, who are interested in participating in a study to collect mobilized blood stem cells that will be used in the laboratory to develop new treatments for blood diseases.

Doctors at the National Institutes of Health (NIH) seek healthy volunteers (with or without a sickle cell trait) and patients with sickle cell for a research study. Sickle cell disease is a genetic blood disorder that occurs mainly in people of African descent. Study participants will have a one-time visit to the NIH to provide blood samples. Researchers hope this study will help us better understand sickle cell disease.

African-American women, ages 25-75, who are obese or overweight and pre-diabetic, are needed to participate in a research study at the National Institutes of Health (NIH) Clinical Center in Bethesda, Maryland. Researchers want to explore if the use of mobile technology and coaching can help increase physical activity.

Does your pace of life in the city affect your health? Researchers at the National Institutes of Health (NIH) are conducting a study of two neighborhoods in Washington, D.C. in relationship to the environmental stress and the health behaviors of White and African American women. This research study will work to determine if there is a significant connection between neighborhood environment and the impact in women's health.

The National Institutes of Health (NIH) seeks healthy volunteers for a study about blood vessel stiffness. In this study, healthy volunteers will be compared with patients with rare genetic conditions that affect the blood vessels. All study-related procedures are provided at no cost and compensation is provided.

Doctors at the National Institutes of Health (NIH) seek healthy volunteers for a research study that is collecting bone marrow samples from healthy adults. Samples will be used for clinical research in the Hematology Branch and are indispensable for many research projects, including studies of normal and abnormal blood cells in the human body, blood diseases, the role of the immune system in marrow failure; and the genetic risk factors for aplastic anemia.

Researchers at the National Institutes of Health (NIH) seek healthy volunteers to provide blood samples for research studies of blood vessels and immune diseases that cause clotting. In this study, investigators want to understand the basis of these diseases to facilitate the development of better treatments.

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.

Researchers at the National Institutes of Health are investigating the role of Near-Infrared Spectroscopy (NIRS) technologies as a monitoring tool for measuring oxygen levels, blood flow, and the make-up of skin and muscle in patients with sickle cell disease (SCD). In this study, researchers will compare NIRS measurements in people with and without SCD.
