NCT00001469
Molecular approaches to the understanding of human neoplastic disease have revealed that multiple genetic alterations are an essential component of tumorigenesis. Both germline and somatic genetic alterations can be involved in the malignant transformation of normal cells. Identification of the genes involved in neoplastic transformation has been approached through the molecular analysis of sporadic cancers and the genetic study of families with an inherited predisposition for cancer. The interplay of these two approaches has led to the characterization of genes such as the retinoblastoma (Rb) gene, the p53 gene and the adenomatous polyposis coli (APC) gene that are all involved in the development of both hereditary and non-hereditary forms of cancer. Inherited mutations in such genes predispose affected families to hereditary cancer syndromes, affording an opportunity to identify genetic lesions that also cause the more common sporadic cancers. Prostate cancer (PRCA) is the most common cancer diagnosed (1999 estimate 179,300 cases) and the second leading cause of cancer mortality (1999 estimate 37,000 deaths) in men in the United States. Family history is the single strongest risk factor currently known for prostate cancer. This raises the possibility that heritable genetic factors may be involved in the development of this disease in a subset of men. The genetic contribution to diseases of complex origin such as cancer is often most salient in families of early onset cases. Therefore, prostate cancer inheritance following a simple Mendelian pattern may be identified in the families of probands with early-onset cases. Common susceptibility alleles of small effect may be detectable in families with later-onsent and/or less strong family history of PRCA or in case-control data.
NCT04019769
Background: Glutamine is an amino acid. People get amino acids from food or from the body s cells. The body needs amino acids to stay healthy. Glutamine might help treat some people with immune system problems like atopic dermatitis. Objective: To study the safety and effectiveness of glutamine supplements for people with certain immune system problems. Eligibility: People ages 5-65 with atopic dermatitis and other immune system problems Design: Participants will be screened in another protocol. Participants will have 8 visits. Visit 1 includes: Physical exam Medical history Blood and urine tests Saliva sample Nutrition assessment For participants with AD, photographs of the skin Participants will get a diary to record their symptoms every day during the study. They will record any glutamine side effects and bring the diary to every visit. Visit 2 is about 1 month after visit 1. Participants will repeat visit 1 tests and get glutamine to take home. It is a powder that can be added to drinks or food. They will take it twice a day for 3 months. They will record their doses in a diary each day and bring the diary to all visits. Participants will have a phone call 5 days after starting glutamine to discuss how they are feeling. Visit 3 is about 7 days after participants start taking glutamine. They will have blood tests. Visits 4, 5, and 6 occur each month participants are taking glutamine. Participants will repeat visit 1 tests. Participants will stop taking glutamine after visit 6. Visits 7 and 8 occur 1 and 3 months after participants stop taking glutamine. Participants will repeat visit 1 tests.
NCT00341549
This study will try to identify the gene or genes responsible for myopia (nearsightedness) and to examine the relationship between myopia and near work. Myopia is the most common eye disorder in the world, affecting one in four Americans. Several studies indicate that myopia is inherited. The condition tends to cluster in families, so that studying families with this condition may facilitate finding the exact cause. Caucasian Americans and African Americans with myopia who are in general good health may be eligible for this study. People with a family history of myopia through several generations along one parent s side only, and in which more than one sibling has myopia are preferred. People who have severe diseases that involve myopia, such as Stickler s or Marfan syndromes, retinitis pigmentosa or diabetic retinopathy may not participate. Participants will undergo the following tests and procedures: * Eye examination, including refraction * Blood draw for genetic studies and possibly establishment of cell lines (collection of cells grown in the laboratory from an original tissue specimen) for future research * Myopia Family Study Questionnaire and personal medical information questionnaire to provide information about other medical conditions that may influence the development of myopia; the vision status of their spouse and children, parents and siblings, and spouse s parents and siblings * Risk Factor Questionnaire (for Jewish Orthodox community only) to assess the amount of near work activity done in childhood
NCT01732770
This study will compare the effectiveness of denosumab treatment every 6 months with once yearly zoledronic acid treatment on bone mineral density (BMD) at various skeletal sites.
NCT01522495
Little is known about chronic wound microenvironments, especially in peripheral vascular disease (PVD) and diabetic patients. At the demarcation line, the percentage of viable cells and tissue is unclear. A means to determine cell viability, particularly discerning an apoptotic or necrotic cell pathway would indicate where the line of demarcation should be drawn. The information generated would better predict clinical outcome using SPY Imaging. Cellular studies are needed to successfully confirm a clear line of demarcation to eliminate surgeon subjectivity.
NCT01867671
This is a randomized, double-blind, placebo-controlled, multi-center study comparing peanut oral immunotherapy (OIT) to placebo in the induction of tolerance and desensitization in peanut-allergic children. Eligible participants with peanut allergy will be randomly assigned to receive either peanut OIT or placebo for 134 weeks followed by peanut avoidance for 26 weeks.
NCT02091271
The National Institute on Aging (NIA) Intramural Research Program (IRP) has a number ofiRB approved research studies involving human subjects, both normal volunteers and patients. As a means of identifying interested volunteers and other participants in the research process, this screening mechanism is established to identif'y potential eligible participants for NlA protocols. To participate, volunteers/patients must meet the specific requirements of at least one of the available NlA research studies; this protocol serves as a first step for admitting volunteers/patients to an appropriate approved protocol and creating a contact database for approved NlA studies. This protocol will facilitate their recruitment into NIA approved studies and provide NlA staff the opportunity to examine subjects where diagnostic observations can be documented and evaluated for research potential.

NCT00524017
RATIONALE: Monoclonal antibodies, such as cetuximab, can block abnormal cell growth in different ways. Some block the ability of abnormal cells to grow and spread. Others find abnormal cells and help kill them or carry cell-killing substances to them. PURPOSE: This randomized phase II trial is studying how well cetuximab works in treating patients with precancerous lesions of the upper aerodigestive tract.
NCT03308331
People living with HIV-1 have high rates of cigarette smoking, which may be related to nicotinic interaction with HIV-1 infection and brain function levels. The proposed project aims to understand these pathways using translational brain imaging and HIV-1 reactivation studies. The study proposes a targeted nicotine-brain investigation of the nicotinic effects in HIV-1 infection from cellular to brain circuitry levels.
NCT02315430
This phase II trial studies how well cabozantinib-s-malate works in treating patients with ovarian, fallopian tube, or primary peritoneal cavity cancer that has come back or is growing, spreading, or getting worse. Cabozantinib-s-malate may stop the growth of tumor cells by blocking the growth of new blood vessels necessary for tumor growth and also by blocking some of the enzymes needed for cell growth.
NCT01452529

NCT01716715
This randomized phase II trial studies how well giving cabozantinib-s-malate or paclitaxel works in treating patients with persistent or recurrent epithelial ovarian, fallopian tube, or primary peritoneal cavity cancer. Cabozantinib-s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether cabozantinib-s-malate or paclitaxel is more effective at treating patients with persistent or recurrent epithelial ovarian, fallopian tube, or primary peritoneal cavity cancer.
