To assess the diagnostic efficacy of diffusion-weighted MR imaging (DWI) for evaluating inflammatory activity in patients with Crohn's disease (CD). A total of 47 CD patients underwent MR enterography (MRE) and DWI using 3 b values of 50, 400, and 800 s/mm. Apparent diffusion coefficients (ADCs) of inflamed and normal bowel wall were calculated. The conventional MRE findings and DWI signal inte...

BACKGROUND & AIMS Capsule endoscopy (CE) detects small bowel Crohn's disease with greater diagnostic yield than radiologic procedures, although there are concerns that CE has low specificity. We compared the sensitivity and specificity of CE, magnetic resonance imaging enterography (MRE) and computed tomography enterography (CTE) in patients with suspected or newly diagnosed Crohn's disease. ...

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

Introduction: MR elastography (MRE) has recently emerged as a tool for the noninvasive assessment of liver fibrosis and a number of studies have indicated its potential role as an alternative to biopsy [1-5]. MRE uses phase-contrast MR techniques to image the propagation of shear waves through tissue in order to determine the mechanical properties of the tissue. One of the advantages that MRE h...

The alpha-MRE is the major regulatory element responsible for the expression of human alpha-like globin genes. It is genetically polymorphic, and six different haplotypes, named A to F, have been identified in some population groups from Europe, Africa and Asia and in native Indians from two Brazilian Indian tribes. Most of the mutations that constitute the alpha-MRE haplotypes are located in f...

Prostacyclin (PGI(2)) and its analogs are useful for the treatment of various vascular disorders, but their half-lives are too short for widespread clinical application. To overcome this drawback, we have synthesized a novel diphenylpyrazine derivative, 2-[4-[(5,6-diphenylpyrazin-2-yl)(isopropyl)amino]butoxy]-N-(methylsulfonyl)acetamide (NS-304), a prodrug of the active form [4-[(5,6-diphenylpy...

AIM To compare the results of high-resolution ultrasound (HR-US) and magnetic resonance enterography (MRE) examinations in patients with inflammatory bowel disease (IBD). METHODS The reports of 250 consecutive cases with known IBD, who had an MRE and HR-US examination, were retrospectively analyzed. Using a patient-based approach we evaluated morphological disease features such as affected bo...

Metallothioneins (MTs) are small metal-binding proteins that have a role in the defense against heavy metals. Mammalian MT genes are transcriptionally activated by metals such as Cd and Zn through multiple copies of the metal responsive element (MRE) present in the 5'-flanking region. To examine whether each MRE in a single promoter has a distinct role, we characterized seven MREs located upstr...

Adaptive systems behavior based on user models appear promising, mostly for complex environments such as mixed reality environments (MRE). An MRE comprises a virtual representation of the reality as well as physical objects augmented with virtual features. These objects are coupled with the virtual representation so that they can reflect its changes in real time. The proper design of an MRE and...

This study analyzed the influence of different ammonia stripping parameters on removal efficiency and mass transfer rate. Ammonia was performed two devices, a column packed tower, with artificial ammonium hydroxide wastewater. First, concentration pH were varied in without liquid circulation. At same pH, rate constant, irrespective initial concentration. When increased, fraction also resulting ...
