Filter by:Background: - Most of the time, humans make decisions according to their consequences, especially if they will be beneficial, and will avoid or try to avoid doing an action if it has a bad outcome. The way that the brain prepares a movement has been studied in detail, but the way the brain makes decisions before carrying out an action is still poorly understood. Researchers are interested in learning more about the decision-making process and how it affects the brain. Objectives: - To record the activity of the brain during decision-making processes. Eligibility: - Healthy, right-handed volunteers between 18 and 40 years of age. Design: - Potential participants will have a screening visit with a medical history and neurological examination to determine eligibility. - This study requires seven visits: one magnetic resonance imaging (MRI) visit and 6 magnetoencephalography (MEG) recording visits. The MEG recording visits will include transcranial magnetic stimulation (TMS). All visits will be spaced at least 1 week apart. Total participation will last about 6 weeks. - Participants will have an MRI scan at the first study visit. - The MEG procedures will record brain activity during a series of computer tests involving winning or losing money. TMS will be performed during these visits, separate from the test....
This research study is collecting and storing tissue samples from patients with rare or cutaneous non-Hodgkin lymphoma. Collecting and storing samples of tissue from patients with cancer to test in the laboratory may help the study of cancer in the future.
This phase II trial studies how well giving liposomal cytarabine and high-dose methotrexate works in treating patients with breast cancer that has spread to the central nervous system. Drugs used in chemotherapy, such as liposomal cytarabine and methotrexate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving liposomal cytarabine with high-dose methotrexate may kill more tumor cells.
This phase I/II trial studies the side effects and best dose of melphalan when given together with carboplatin, mannitol, and sodium thiosulfate, and to see how well they work in treating patients with central nervous system (CNS) embryonal or germ cell tumors that is growing, spreading, or getting worse (progressive) or has come back (recurrent). Drugs used in chemotherapy, such as melphalan and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Osmotic blood-brain barrier disruption (BBBD) uses mannitol to open the blood vessels around the brain and allow cancer-killing substances to be carried directly to the brain. Sodium thiosulfate may help lessen or prevent hearing loss and toxicities in patients undergoing chemotherapy with carboplatin and BBBD. Giving melphalan together with carboplatin, mannitol, and sodium thiosulfate may be an effective treatment for recurrent or progressive CNS embryonal or germ cell tumors.
The purpose of this study is to compare the efficacy of anidulafungin versus fluconazole for the prevention of fungal diseases in liver transplant recipients
This phase II trial studies the side effects and how well carmustine, etoposide, cytarabine and melphalan together with antithymocyte globulin before a stem cell transplant works in treating patients with autoimmune neurologic disease that did not respond to previous therapy. In autoimmune neurological diseases, the patient's own immune system 'attacks' the nervous system which might include the brain/spinal cord and/or the peripheral nerves. Giving high-dose chemotherapy, including carmustine, etoposide, cytarabine, melphalan, and antithymocyte globulin, before a stem cell transplant weakens the immune system and may help stop the immune system from 'attacking' a patient's nervous system. When the patient's own (autologous) stem cells are infused into the patient they help the bone marrow make red blood cells, white blood cells, and platelets so the blood counts can improve.
This phase I trial is studying the side effects and best dose of sunitinib in treating young patients with refractory solid tumors. Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for their growth and by blocking blood flow to the tumor.
RATIONALE: Drugs used in chemotherapy, such as etoposide and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Thalidomide, celecoxib, and fenofibrate may stop the growth of cancer cells by blocking blood flow to the cancer. Celecoxib also may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with thalidomide, celecoxib, and fenofibrate may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving etoposide and cyclophosphamide together with thalidomide, celecoxib, and fenofibrate works in treating young patients with relapsed or progressive cancer.
RATIONALE: Zoledronate may prevent bone loss in patients with primary malignant glioma. PURPOSE: This phase II trial is studying how well zoledronate works in preventing osteoporosis in patients with primary malignant glioma.
RATIONALE: Thalidomide may stop the growth of tumor cells by stopping blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining thalidomide with temozolomide may kill more tumor cells. PURPOSE: This phase II trial is studying the effectiveness of combining thalidomide with temozolomide in treating young patients who have relapsed or progressive brain tumors or recurrent neuroblastoma.
