Cognitive Task Development and Implementation for Functional MRI Studies
Recruiting
Background:
* Drugs of abuse have effects on mood, behavior, thinking, and decision making that may encourage people to continue using them and make it difficult for them to stop. Researchers who study these effects are interested in developing new tests to evaluate how drugs and drug use affect different areas of the brain.
* Magnetic resonance imaging (MRI) scans allow researchers to study brain activity and changes to brain function. When specific psychological tests are performed during fun... Read More

Children s Growth and Behavior Study
Recruiting
Background:
- Studies show that many factors affect children's eating behavior and health. These include sleep, mood, thinking skills, and genetics. Studying children over time may identify children at higher risk for eating-related health concerns.
Objective:
- To understand how genes and environment influence eating behavior and health over time.
Eligibility:

Study of New Magnetic Resonance Imaging Methods of the Brain
Recruiting
The purpose of this investigation is to develop improved magnetic resonance imaging (MRI) techniques and hardware for studying brain function. MRI is a diagnostic tool that provides information about brain chemistry and physiology. This study will evaluate new MRI methods for monitoring blood flow to regions of the brain in response to simple tasks. The MRI machine used in this study is more powerful than those in most hospitals, permitting a higher visual resolution.

Characterization of Nociception Phenotype in Individuals With Intellectual Disability
Recruiting
Background:
People with intellectual disability (ID) often have physical disabilities as well. These physical problems can affect their bones, muscles, nerves, and gastrointestinal tracts. All of these issues can also cause pain. Yet little research has been done on pain in people with ID.
Objective:
To compare brain responses to unpleasant stimuli in people with and without ID.
Eligibility:
People aged 8 to 30 years diagnosed with an ID. Healthy volunteers without an ID are also needed.

Urinary Vitamin C Loss in Diabetic Subjects
Recruiting
Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled vitamin C intake, inadequate sampling, lack of control subjects, or methodology uncertainties in vitamin C assay and sample processing. Consequently, it is unclear whether diabetic subjects truly have both low plasma an... Read More

Evaluating New Radiation Techniques for Cardiovascular Imaging
Recruiting
Title: Evaluating New Radiation Techniques for Cardiovascular Imaging
Background:
- Imaging studies such as computed tomography (CT) scans involve the use of radiation to create the pictures. Heart and blood vessel CT scans can cause high radiation exposure. Different methods of creating CT pictures have been developed to reduce the radiation dose. Researchers want to see how effective these new methods are in producing accurate CT scans.

Psychological Benefits of a Normalized Camping Experience for Children With Cancer
Recruiting
Background:
* Cancer has an enormous impact on the psychological and social well-being of the family unit. The life-threatening connotations of cancer single out the ill child from his peer/family group as one who is different, and often unable to maintain a normal lifestyle. Physical sequelae of cancer and its treatment accentuate the differences between these children and their normal peers/siblings.
* It is important that children with cancer be prepared to function outside of protected situ... Read More
