Natural History Study of Biomarkers in Pulmonary Arterial Hypertension
Background High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. Some people have disease-associated PAH and some have PAH from an unknown cause. Researchers want to follow the natural history of all PAH patients to understand how PAH progresses in order to discover …
Observational Study to Deeply Phenotype Major Organs in Sickle Cell Disease After Curative Therapies
Background People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant.

Acquisition of Blood and Tumor Tissue Samples From Patients With Gastrointestinal Cancer
Background Gastrointestinal cancers can occur in the throat, stomach, gallbladder, liver, pancreas, and colon. Researchers are interested in evaluating how active the immune system is in trying to fight the cancer by studying blood and tumor tissue donated from individuals who have been diagnosed with gastrointestinal cancers. Objectives To collect …
A Longitudinal Investigation of the Endocrine and Neurobiologic Events Accompanying Puberty
Despite the clear importance of adolescence in the emergence of a number of disease states and processes, there is surprisingly little known about how the endocrine and metabolic events accompanying puberty in humans impact normal developmental neurobiology. Epidemiologic studies have identified sexual dimorphisms in the prevalence of several neuropsychiatric disorders, …
