The present protocol is designed to create a "scaled-down" hormonal milieu of pregnancy and the puerperium in order to determine whether it is the abrupt withdrawal of gonadal steroids or the prolonged exposure to gonadal steroids that is associated with mood symptoms.

Pulmonary lymphangioleiomyomatosis (LAM) is a destructive lung disease typically affecting women of childbearing age. Currently, there is no effective therapy for the disease and the prognosis is poor. This study is designed to determine the disease processes involved at the lev…

Lentiginosis refers to groups of diseases marked by the presence of pigmented spots on the skin. These conditions are most commonly associated with multiple tumors and changes in hormone producing glands. The cause of these diseases is unknown, but researchers suggest there may b…

The prospect of disease-modifying therapies in the pipeline for Alzheimer's Disease (AD) has intensified efforts to use brain imaging more effectively for diagnosis and monitoring of dementing illnesses. There is also emerging awareness of the destructive interplay between AD and…

This randomized phase III trial is studying surgery and axillary lymph node dissection to evaluate if systematic Axillary Lymph Node Excision can be avoided in locoregional treatment for operable breast cancer smaller than 10 mm among menopausal women older than 50

The goal of the study is to gain a better understanding of the molecular changes responsible for causing prostate cancer and that examination of tissue and blood samples will help in the development of improved screening and therapeutic approaches.

The Childhood Cancer Survivor Study (CCSS) will investigate the long-term effects of cancer and its associated therapies. A retrospective cohort study will be conducted through a multi-institutional collaboration, which will involve the identification and active follow-up of a co…

This study looks to identify genes that may affect a person's chances of developing bipolar disorder (BP) and related conditions.

The Diabetes Control and Complications Trial (DCCT,1983-1993) compared intensive therapy aimed at near-normal glycemia versus conventional therapy with no specific glucose targets in 1441 subjects with type 1 diabetes (T1DM) over a mean follow-up of 6.5 years. Intensive therapy r…

This study is designed to explore the genetics and pathophysiology of diseases presenting with intermittent fever, including familial Mediterranean fever, TRAPS, hyper-IgD syndrome, and related diseases. The following individuals may be eligible for this natural history study: 1…

This clinical trial studies whether screening methods used to diagnose cancer of the prostate, lung, colon, rectum, or ovaries can reduce deaths from these cancers. Screening tests may help doctors find cancer cells early and plan better treatment for lung cancer.

The "Agricultural Health Study" (AHS) is a collaborative effort between the National Cancer Institute and the National Institute of Environmental Health Sciences. The U.S. Environmental Protection Agency and the National Institute for Occupational Safety and Health are providing …

The UKGPCS was set up to find genetic alterations which occur in patients who have prostate cancer. A man's risk of developing prostate cancer increases if he has a first-degree relative (father or brother) who was diagnosed with prostate cancer at a young age. This is why we ar…

Homozygous familial hypercholesterolemia is a rare inherited disease of metabolism. It occurs in less than 1 in 1 million people within the United States. Patients with the disease are typically children and young adults who develop heart disease early in life. Children less than…

BTX has been used since the 1980s in support of the research mission of NINDS. Initial studies were focused on expanding the applicability of BTX treatment to movement disorders and exploring new indications. We evaluated the efficacy of an alternative serotype, type F. Under oth…

This study will compare the effectiveness of zidovudine (AZT) alone vs. zidovudine plus interferon (IFN) vs. interferon alone in reducing HIV viral load, lessening immune system deterioration, and increasing the time to development of the first opportunistic infection in HIV-infe…

To determine the relationships of hormonal, reproductive, dietary, and lifestyle factors, as well as biochemical and genetic factors, with the subsequent risk of coronary heart disease and other cardiovascular events in a cohort of female registered nurses. The current funding cy…

This project is a continuation of an extensive longitudinal population-based epidemiological investigation of the etiology and determinants of type 2 diabetes (and its complications) and formerly arthritis. The original baseline observations were made on the residents of the Gila…

This is an expanded access program (EAP) for eligible participants. This program is designed to provide access to ABBV-706 prior to approval by the local regulatory agency. Availability will depend on territory eligibility. A medical doctor must decide whether the potential benef…
