Résumé : Dans une ontologie de domaine, une association sémantique entre deux entités (concepts, attributs d’un concept) est une représentation d’un chemin ou d’un lien sémantique (LS) indirect entre elles. Un défi prometteur pour le Web sémantique est de développer des méthodes pour découvrir des données fortement liées dans un nombre important d’associations sémantiques rassemblées à partir d...

Photoionization of the Ce Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our results with the recent measurement [Müller et al, Phys. Rev. Lett. 101, 133001 (2008)] confirms the suppression effect of the carbon cage in the endohedral fullerene Ce@C+82 photoionization. The reasons for the cause of the confineme...

Résumé— Une phase primordiale lors de la modélisation d’un système à l’aide d’un perceptron multicouches reste la détermination de la structure du réseau. Dans ce cadre, nous proposons un algorithme d’élagage du réseau basé sur l’utilisation de l’analyse de la variance de la sensibilité de tous les paramètres du réseau. Cet algorithme sera testé sur deux exemples de simulation et ses performanc...

Angiogenesis is controlled by number of growth factors, including vascular endothelial growth factor (VEGF). Plant derived anti-angiogenic molecules acting via VEGF are being investigated for curtailing angiogenesis dependent diseases. In this study, methanolic (CM), n-hexane (CH), ethylacetate (CE) and water (CW) extracts of the roots of Calotropis procera were tested for anti-angiogenic activ...

Objective This study was performed to analyse factors influencing the effect-site concentration (Ce) of propofol at return of consciousness (ROC) with target-controlled infusion of propofol-remifentanil after laparoscopic surgery. Methods In total, 112 patients who underwent laparoscopic surgery under general anaesthesia were given propofol at the target concentration of 3.5 µg/ml. Remifentanil...

OBJECTIVES To study early haemodynamic changes in connection with carotid endarterectomy (CE). METHODS Sixty-three consecutive patients, average age 64, with symptomatic stenosis in the internal carotid artery (ICA) > or = 70% were examined clinically and by transcranial Doppler (TCD) 1 day before and within 48 h after CE. Duplex scanning of extracranial vessels was performed within 1 week af...

Mycoplasma pneumoniae is usually susceptible to macrolides, but macrolide-resistant strains have been found frequently in recent years. Mutations in domain V of the 23S rRNA gene of M. pneumoniae interfere with the binding of macrolides to rRNA and mediate macrolide resistance. In this study, we developed a rapid and inexpensive method that combines nested PCR (nPCR), single-strand conformation...

PURPOSE To determine whether contrast-enhanced 3D MR angiography (CE MRA) could replace digital subtraction angiography (DSA) for the evaluation of atherosclerotic peripheral vascular disease of the lower leg and foot. MATERIAL AND METHODS Thirty-five patients with symptoms of atherosclerotic disease of the leg were examined prospectively with CE MRA of the foot and the lower legs as well as ...

BACKGROUND & AIMS Capsule endoscopy (CE) and double-balloon enteroscopy (DBE) allow complete small-bowel examination but consume additional health care resources. A cost-minimization analysis determined the optimal initial management strategy for obscure occult gastrointestinal bleeding (OGIB). METHODS We compared 5 strategies: initial small-bowel follow-through, enteroclysis, push enteroscop...
