Background: * Chromatin is is the structural building block of a chromosome. It is found inside the nucleus of the cell and consists of a complex of DNA and protein. * Cancers of the lung, pleura (lung lining) and esophagus show profound changes in chromatin structure that may a…

The primary objective of the protocol is to develop a comprehensive specimen banking program from patients with lung cancer for future translation research, which will enable the investigators to detect lung cancer earlier, develop better therapies and explore screening and preve…

The purpose of this study is to determine whether the structure and function of the human retina can be studied with high resolution in patients with inherited retinal degenerations using the Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO).

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPO…

The overall goal of this project is to understand the mechanisms by which gastric bypass surgery improves glucose metabolism. The central hypothesis guiding this project is that the reconfiguration of intestinal transit with the Roux-en-Y will increase the release of insulinotro…

The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be signi…

To validate a new method for assessing perioperative risk in the cancer patient undergoing major cancer surgery. In this proposed study researchers will: 1. Measure preoperative energy reserve capacity (fitness) 2. Determine if postoperative morbidity is a function of periopera…

This study will test the Protecting Families Program, a 10-week prevention program for depressed parents and their pre-teenage children, by comparing the effectiveness of the program versus parent training alone.

This study will evaluate patients with abnormal immune function that results in recurrent or unusual infections or chronic inflammation. This may include inherited conditions, such as X-linked severe combined immunodeficiency (XSCID), chronic granulomatous disease (CGD), and leuk…

The purpose of this study is to determine in a large, double-blind, randomized, prospective pediatric clinical trial whether the use of continuous levalbuterol (Xopenex) in addition to standard emergency department treatment for acute asthma exacerbations will improve the Forced …

Blood contains red blood cells, white blood cells, and platelets, as well as a fluid portion termed plasma. We primarily study blood platelets, but sometimes we also analyze the blood of patients with red blood cell disorders (such as sickle cell disease), white blood cell disord…

Brain damage as a result of decreased oxygen to the brain is found in 80% of patients that die with severe head injuries. Laboratory studies in animals and clinical trials have shown that increasing oxygen in the brain results in better brain oxygen consumption, less cell death, …

Adrenocortical carcinoma (ACC) is a rare and heterogeneous malignancy with poor prognosis. Surgical resection of the tumor is the treatment of choice. However, even after complete resection more than 80 % of patients will experience recurrence of disease. Therefore, new treatment…

This study will evaluate the long-term functional status, psychosocial adjustment and quality of life of patients with different types of diseases and conditions who have had an allogeneic (donor) stem cell transplant. Information from this study may help patients and families kn…

Background: Detrimental effects of consumption of industrial trans fatty acids (TFA) from partially hydrogenated vegetable oils (PHVO) on cardiovascular disease (CVD) risk factors are well documented. However, very little information is available on the effect of natural sources…

This is a phase II multi-centre study in 140 patients undergoing elective PCI to obtain the information on dose-response of argatroban in pharmacodynamic markers and to assess the anticoagulation, safety and efficacy of argatroban in reference to unfractionated heparin, in combin…

This study will define the major genetic risk and protective factors for idiopathic inflammatory myopathies (IIM), a group of immune disorders affecting connective tissues such as muscles. It will also identify new environmental risk factors for IIM and identify immune responses …

Over half of adults in this country are overweight. This increases risk for heart and blood pressure problems, cancer, stroke and arthritis. While it is difficult to lose large amounts of weight and keep it off, even small amounts of weight loss can improve health. Furthermore, f…

The primary objective of this study is to evaluate plasmatic concentrations of free PGF and sFlt1 for blood samples taken before a first low-molecular-weight-heparin injection and also for blood samples taken on the 4th day of injections (the latter correspond to the first system…

This study will evaluate the link between blood group antigens and asthma exacerbations.
