BACKGROUND/AIMS Capsule endoscopy (CE) is currently recommended as the first-line study in the evaluation of obscure gastrointestinal bleeding (OGIB), while computed tomography (CT) is often thought of as complementary to CE. This study evaluated CT as a first-line study in OGIB and compared it with CE. MATERIALS AND METHODS Ninety-nine patients with OGIB who received both CE and CT were incl...

Mice were inoculated with St. Louis encephalitis (SLE), Flanders (FLAN), California (CE), or Tensaw (TEN) viruses. At fixed intervals after inoculation, brains from these mice were coUected and assayed for infective virus and complement-fixing, hemagglutinating, and precipitating antigens. Detectability of these antigens was correlated with the appearance of signs of illness in the mice. Infect...

The results of repeated interphase fluorescence in-situ hybridization (I-FISH, FISH) examination of 97 CLL patients and correlation of these findings with IgVH hypermutation status, ZAP-70 and CD38 expression are presented. The appearance of new, FISH-detectable, genomic aberrations during disease course, described as clonal evolution (CE), was observed in 26% of patients. The most frequent new...

We conducted a questionnaire-based case-control study to identify risk factors for cystic echinococcosis (CE) in Lima, Peru during July-December 2005. Data were obtained from 32 cases and 64 controls. Multivariate conditional logistic regression showed that having owned > or =10 dogs [adjusted odds ratio (AOR) 8.7, 95% CI 1.3-57.5) and raising sheep (AOR 5.9, 95% CI 1.2-28.1) were independently...

AIMS Both contrast enhanced (CE) two-dimensional echocardiography (2DE) and three-dimensional echocardiography (3DE) have been proposed as techniques to improve the accuracy of left ventricular (LV) volume measurements. We sought to examine the accuracy of non-contrast (NC) and CE-2DE and 3DE for calculation of LV volumes and ejection fraction (EF), relative to cardiac magnetic resonance imagin...

Nioboaeschynite-(Ce), ideally Ce(NbTi)O(6) [cerium(III) niobium(V) titanium(IV) hexa-oxide; refined formula of the natural sample is Ca(0.25)Ce(0.79)(Nb(1.14)Ti(0.86))O(6)], belongs to the aeschynite mineral group which is characterized by the general formula AB(2)(O,OH)(6), where eight-coordinated A is a rare earth element, Ca, Th or Fe, and six-coordinated B is Ti, Nb, Ta or W. The general st...

La théorie des réseaux de Petri est née de la thèse de Carl Adam Petri [PE 62]. Mais, bien d’autres chercheurs ont contribué à ce qui est devenu “les réseaux de Petri”. Certains sont explicitement partis des travaux de Carl Adam Petri, les ont légèrement modifiés et ont développé les notions que ce dernier avait introduites. D’autres ont menés indépendamment des travaux sur la représentation et...
