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 mon…

Doctors at Memorial Sloan Kettering Cancer Center and at other institutions study normal and cancer cells. To study these cells we need to have human tissue, body fluids, and blood. The patient will be having or have had a procedure to remove tissue. The doctors would like to use…

The purpose of this study is to use brain imaging technology to compare differences in brain structure, chemistry, and functioning in individuals with brain and mental disorders compared to healthy volunteers. Schizophrenia is a brain disorder that results from subtle changes an…

RATIONALE: Collecting and storing samples of blood, urine, tissue and data from patients with amyloid diseases to test in the laboratory may help the study of this disease in the future. PURPOSE: This research study is collecting samples from patients with amyloid diseases

The purpose of this study is to collect human Chronic Lymphocytic Leukemia tissue samples and medical information, in order to find out more about the causes and biology of chronic lymphocytic leukemia.

Background: The National Cancer Institute Surgery Branch (NCI-SB) has developed experimental therapies that involve taking white blood cells from patients' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. …

This trial studies how well a new assessment system (MDASI or other MD Anderson-developed PRO instrument) works in measuring symptoms and the impact on quality of life in cancer patients. Development of a new assessment system may provide more information about the common symptom…

The aim of this research study is to collect and store the specimens that are left over after patients undergo tests ordered by their physicians. These specimens will be used at a later time by researchers in the Pulmonary Division to develop a better understanding of pulmonary d…

The purpose of this study is to characterize the molecular and cell biology of the tumor cells in lymphoma.

Selected individuals suspected of having or with prior biopsy proof of malignant disease will be seen in the Urologic Oncology Branch, NCI. Blood samples may be collected at the time of the initial visit and at periodic intervals during the course of the disease. These samples wi…

The specific aim of the study is to obtain long-term follow-up information on patients who have completed their standard clinical care in the Orthopaedic Hand and Upper Extremity Service. The study will help to qualify and quantify long-term recovery and outcomes from uncommon up…

Cross-over study. Patients treated with peritoneal dialysis are investigated twice with a single 4h dwell study: once with Bicarbonate-Lactate solution as buffer (Physioneal TM) and once with conventional lactate PD solution (Dianeal TM). Radioidinated human serum albumin is used…

This study will investigate how, why and under what conditions eosinophils (a type of white blood cell) become activated and will examine their function in immune reactions. Eosinophil counts often rise in response to allergies, asthma, and parasitic worm infections. They can als…

Under Transplant Information Services (TIS), the University of Minnesota Transplant Registry (UMTR) will serve as the repository for core research data.

Pharmacokinetics is the term used for how the body affects a drug once it is taken. Vitamin C, also known as ascorbic acid, is an essential water soluble vitamin. Meaning, the body does not make Vitamin C it must be taken in through the diet. In this study researchers will attemp…

The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity in patients harboring pituitary mass lesions of all types.

This project is based on the idea that we can learn about the complexities of MS by following disease and treatment patterns in a large group of people over several years. The information gathered is used for research only. Results are presented in summary form only. All details …

This study will examine tissue from the tonsils, lymph nodes and large bowel of HIV-infected patients to investigate changes in viral load and certain white blood cells during treatment. Normal volunteers and HIV-infected patients 18 years of age or older may be eligible for thi…

The purpose of this study is to use brain imaging technology to measure changes in blood flow to areas in the brain as individuals perform intellectual tasks. This study will use functional magnetic resonance imaging (fMRI) to examine blood flow to areas of the brain as particip…

This study will investigate inflammatory diseases and disorders. Inflammation is the body s immune response to many things, including infections and other acute or chronic irritants. It may also be a sign of abnormal immune function. This study will allow evaluation and long-term…
