BACKGROUND The aim of this study was to investigate the efficacy of capsule endoscopy (CE) performed on patients who presented to emergency room with clinically evident gastrointestinal (GI) bleeding from unknown source and were hospitalized for follow-up. METHODS Total of 38 patients who underwent CE and were followed-up for evaluation of clinically perceptible GI bleeding with no obvious et...

A recA-like gene was identified in the Caenorhabditis elegans genome project database. The putative product of the gene, termed Ce-rdh-1 (C. elegans RAD51 and DMC1/LIM15 homolog 1), consists of 357 amino acid residues. The predicted amino acid sequence of Ce-rdh-1 showed 46-60% identity to both RAD51 type and DMC1/LIM15 type genes in several eukaryote species. The results of RNAi (RNA-mediated ...

RÉSUMÉ. De nos jours, les intergiciels à composants sont utilisés pour concevoir, développer, et déployer facilement les applications réparties, et assurer l’hétérogénéité, et l’interopérabilité, ainsi que la réutilisation des modules logiciels, et la séparation entre le code métier encapsulé dans des composants et le code système géré par les conteneurs. De nombreux standards répondent à cette...

Knowledge Management (KM) is a complex objective, especially in the instance of extended enterprises consisting of SMEs, and critical in new product design and development (NPD). The use of patterns is essential to get KM in collaborative NPD processes. This paper presents the use of patterns adopted in the CE-TILE project to standardize information and knowledge in collaborative work. The diff...

Contrast-enhanced digital breast tomosynthesis (CE-DBT) is a novel modality for imaging breast lesion morphology and vascularity. The purpose of this study is to assess the feasibility of dual-energy subtraction as a technique for CE-DBT (a temporal subtraction CE-DBT technique has been described previously). As CE-DBT evolves, exploration of alternative image acquisition techniques will contri...

The homoleptic organocerium complex Ce{C(SiHMe2 )3 }3 (1) reacts with B(C6 F5 )3 to produce the zwitterionic bis(alkyl) hydridoborato Ce{C(SiHMe2 )3 }2 HB(C6 F5 )3 (2). NMR and IR spectroscopy and X-ray crystallography indicate that each alkyl ligand contains two bridging Ce↼H-Si interactions in both 1 and 2. Compound 2 serves as a precatalyst for the hydrosilylation of acrylates to give α-sily...

Résumé. La fragmentation horizontale est une technique d’optimisation non redondante de requêtes décisionnelles de type ROLAP. L’utilisation de cette technique dans les entrepôts de données représente un enjeu plus important que dans un contexte de bases de données traditionnelles. Cette importance est due au différents choix des tables (de dimensions ou des faits) à fragmenter. Dans le context...

A series of ceria nanocatalysts have been prepared to study the structure dependency of the CO oxidation reaction. The ceria samples with well-defined nanostructures (nanocubes/Ce-NC and nanorods/Ce-NR) have been prepared using the hydrothermal method. Mesoporous ceria (Ce-MES) and ceria synthesized with solution combustion technique (Ce-SCS) have also been prepared for comparison. The lowest C...
