This study will investigate how to better predict why some individuals gain or lose weight more easily than others. It will examine whether the increase in the amount of energy a body burns in 24 hours with overeating or the decrease over 24 hours with fasting can help determine …

Phase I, open study to assess the effect of rifampicin, a marketed drug, on how the body handles the experimental drug cediranib in patients with advanced cancer.

Many control mechanisms exist which successfully match the supply of blood with the metabolic demand of various tissues under wide-ranging conditions. One primary regulator of vasomotion and thus perfusion to the muscle tissue is the host of chemical factors originating from the …

Hypothesis: SLE and RA increase risk of myocardial infarction (MI, heart attack). Immune reactants in the circulation of SLE patients downregulate cholesterol efflux proteins 27-hydroxylase and ABCA1 and upregulate scavenger receptor CD36, thus encouraging cholesterol accumulatio…

The G protein-coupled receptors (GPCRs) are a family of proteins expressed at the cell membrane. They are composed of 380 members involved in the important functions of the organism and are privileged therapeutic targets.Their expression is highly modulated depending on the metab…

The purpose of this project is to obtain DNA, brain imaging data, other biological samples (e.g., urine, serum), and a comprehensive clinical assessment on patients with schizophrenia and other psychotic disorders, bipolar disorder, major depression, and normal volunteer controls…

The purpose of this study is to compare the difference between two magnetic resonance imaging (MRI) techniques for visualizing arteries. The study hypothesizes that one method that relies upon imaging flowing blood in the pelvic and leg arteries will not be as accurate or efficie…

This is a population-based retrospective, new-user design, active comparator cohort study assessing whether initiating a new outpatient prescription of high-dose serotonin norepinephrine reuptake inhibitors (SNRIs)-venlafaxine (\>37.5-150 mg/day) or duloxetine (\>30-120 mg/day), …

HIV-1 cannot be eradicated from infected individuals by current antiretroviral regimens. Cellular reservoirs and tissue sanctuary sites allow latent HIV-1 persistence and ongoing low-level virus replication. This project aims to characterize the residual replication of HIV-1 in s…

Fiberoptic bronchoscopy (FOB) is an important tool for the diagnosis of pulmonary diseases, more particularly in infectious pneumonia. In patients with severe acute hypoxemic respiratory failure, FOB may be contra-indicated until the patient is intubated and control of its oxygen…

This study will evaluate members in families with a history of small bowel carcinoid cancer to study the natural history of those family members that have the disease, determine ways to improve early detection by performing surveillance on those at risk but without disease and to…

The goal of this clinical research study is to learn if draining the IPC every day is better at than draining it 3 times a week.

The purpose of this study is to learn about the quality of life of people living with bladder cancer. We are interested in learning about how the treatments for bladder cancer affect people. We plan to use the findings from this study to help doctors provide better care and infor…

The purpose of this study is to identify neurocognitive functions and language processing of 8-year-old children who were fed either breast milk, milk-based formula or soy-based formula during the first year of life.

The investigators' overall hypothesis is that appearance or worsening of relapsing-remitting multiple sclerosis (RR-MS) symptoms are affected by various factors including stress, hormonal cycles, illness and missed medications.

Sudden death is a natural death occurring within one hour after the onset of symptoms. It remains a major public health problem and accounts for 5 to 10 % of the annual total mortality ie about 300.000 in the United States. Despite community-based interventions, overall survival …

This clinical trial studies how well a long-term follow-up works in patients with prostate cancer after surgery. Long-term follow-up data may serve as a resource to help ask clinical questions, describe health-related quality of life and long-term complications related, and facil…

This clinical trial keeps track of and collects follow-up information from patients who are currently enrolled on or have participated in a Children's Oncology Group study. Developing a way to keep track of patients who have participated in Children's Oncology Group studies may a…

This project examines whether individuals' amount of activity energy expenditure (AEE) is related to adiposity and adiposity/diabetes-related hormones in a diverse sample of 2500, and to test the ecological hypothesis that a decline in levels of AEE is an important cause of the i…

The purpose of this study is to describe bone status on patients with genetic hemochromatosis, at diagnostic time and his evolution under treatment.
