Magnetic Resonance (MR) Enterography Assessment of Post Operative Small Bowel Length in Short Bowel...
Short Bowel SyndromeIt is essential to know intestinal length and anastomotic type in post-operative short bowel syndrome patients. These parameters can help predict long-term intestinal failure with long-term parenteral nutrition usually needed for smallest lengths. Sometimes these parameters are unfortunately missing for lack of intraoperative measurement. Thus, it is necessary to develop non-invasive and reproducible techniques to assess small bowel length. This is the reason why the investigators will evaluate magnetic resonance (MR)-enterography and barium follow-through in this indication. There are at this time only two small studies evaluating barium follow-through for intestinal length measurement, and none evaluating MR-enterography. However, a major advantage of the latter is the lack of radiation exposure and possibility to perform 3D. This will be an open labelled single center crossover study. Short bowel syndrome patients of the investigators center will be included after consent. The sequence of exams (MR enterography followed by barium follow-through or vice-versa) will be randomly assigned. Peroperative short bowel length measurement will be available for all patients. There will be one month between the two exams. The main objective of this study is to assess the performance of MR-enterography in short bowel measurement in short bowel syndrome patients, the gold standard being peroperative length. Secondary objectives are to assess the performance of barium follow-through in short bowel measurement in these patients, and to show that barium follow-through does not perform better than MR-enterography. For that purpose the investigators will include 50 patients over 2 years.
Mechanisms of Mitochondrial Defects in Gulf War Syndrome
Gulf War SyndromeMitochondrial DiseaseThe purpose of the study is to investigate possible causes for Gulf War Syndrome. Gulf War Syndrome is associated with increased incidences of amyotrophic lateral sclerosis (Lou Gehrig's Disease), pain syndromes, muscle complaints that include fatigue and myalgias (muscle pain), as well as other neurological symptoms. Abnormalities in the part of the cell known as mitochondria have been delineated in Gulf War Syndrome. Mitochondria are the "power plants" of the body. Mitochondria take the food you eat and break the food down into a form of energy that the body can use. The investigators propose that Gulf War Syndrome is determined by a complex interaction of factors that interfere with mitochondrial function. This study will be the first investigation of mitochondrial function in Gulf War Syndrome. The investigators objective is to establish the cause for symptoms in affected veterans, develop testing that can more easily identify Gulf War Syndrome, and ultimately develop treatment protocols for Gulf War Syndrome.
Air Pollution, Inflammation and Acute Coronary Syndrome
Patients With Acute Coronary SyndromeThe objectives of this study are: 1) To determine whether patients with acute coronary syndrome, the level of environmental exposure to particulate air pollutants in the week prior to admission, are related to concentrations of inflammatory molecules and oxidative stress. 2) To investigate whether the level of environmental exposure is an independent prognostic factor in terms of overall and cardiovascular mortality, myocardial infarction or unstable angina at 30 days, 6 and 12 months.
Salivary Biomarkers for Sjögren's Syndrome Detection
Sjögren's SyndromeThis is a multi-center clinical study to compare the performance of a collective panel of salivary biomarkers to discriminate SS from non-SS in sicca cohorts recruited from three clinical sites with the diagnostic outcomes based on the new classification criteria for Sjögren's syndrome by the American College of Rheumatology (ACR) developed in 2012. This is not a treatment study, but a pilot study to confirm diagnostic ability of a panel of salivary biomarkers. All enrolled subjects must be classified as having both oral and ocular sicca symptoms without another autoimmune/connective tissue disease (Appendix 2). At the University of California in Los Angeles, using molecular techniques, we will quantify discriminatory biomarkers in saliva collected from enrolled subjects, who are also being evaluated as part of their clinical care using the standard diagnostic tests of the 2002 AECG criteria. We also will test the performance of these biomarkers to predict the diagnosis of pSS according to the AECG criteria, as these are the most widely used tests to diagnose pSS and assess disease activity worldwide.
The Study of LTBP1 of Postmenopausal Women Osteoporosis Molecular Mechanism of Kidney Yang Deficiency...
Kidney Yang Deficiency SyndromePostmenopausal Osteoporosis is characterized by a decrease in bone mass as well as a deterioration of the bone architecture resulting in an increased risk of fracture,which is directly related to the lack of estrogen and also associated with a variety of genetic and acquired factors. Previous studies have found that POP molecular regulation mechanism of kidney Yang deficiency syndrome may be associated with LTBP1 gene expression. This topic using RT-PCR and Western Blot detection POP of kidney Yang deficiency group and healthy group LTBP1 mRNA and proteion's expression level,validate LTBP1 relevance to POP the kidney Yang deficiency syndrome.To provide a scientific basis for clinical treatment.

Molecular Screening for Lynch Syndrome in Denmark
Colorectal CancerLynch Syndrome1 moreA clinically applicably strategy for molecular screening for Lynch Syndrome is being implemented in Denmark. Based on sequential analysis with immunohistochemistry and methylation analysis, patients with possible hereditary colorectal cancer are identified. These patients are offered genetic risk assessment and counselling. The study hypothesis is that molecular screening will identify more patients with Lynch Syndrome than the family history alone. Prospective data collection is performed using established clinical databases.
Systemic Inflammatory Response Syndrome (SIRS) in Patients Undergoing Major Procedures in Oral and...
Systemic Inflammatory Response Syndrome (SIRS)Patients undergoing major procedures in oral and maxillofacial surgery more often develop a systemic inflammatory response syndrome (SIRS) in the first days of postoperative critical care therapy than patients with a comparable major surgery in other regions. The reasons for this finding are unknown and have not been studied in depth so far. We hypothesize that surgical trauma in this region might activate pro-inflammatory pathways. By examining the proteome of patients at different stages (prior to the surgery, at ICU admission, on the second postoperative day and when SIRS has ended clinically), we aim to identify the involved pro-inflammatory pathways and identify possible target proteins that might be clues to modification of postoperative SIRS in the future.
