background: carotid artery stenting (cas) has recently been recommended as an alternative to carotid endarterectomy (cea) by some clinicians. objective: this study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in iran for cas with protection devices, to document our results and guide further use of cas. methods: from december 2003 t...

PNEUllOTHORAX DE L'ENFANT  Presentation de 17 cas. Revue de la litterature Par: Marandian M.H., Momenzadhe A., Wali­zade G., Kabiri M., A'skari H. et Movasat M.  Durant deux ans et demi, 17 cas de pneumo­thorax ont ete observes dans le service de Pedia­trie de !'Hospital Pahlavi de l'Univm-site de Teheran:  1)9 de ces malades etaient ages de moins d'un an. Le malade le plus age atteint de pn...

L’emphysème lobaire géant (ELG) est une cause rare de détresse respiratoire. Il est caractérisé par une distension alvéolaire homogène intéressant le plus souvent un lobe pulmonaire. Nous en rapportons trois cas, colligés au service de néonatologie et soins intensifs: un nouveau-né âgé de 27 jours, et deux nourrissons âgés respectivement de 4 et 6 mois. Le crit è re d’inclusion est basé sur l’e...

This paper presents a GPU implementation of an asynchronous iterative algorithm for computing incomplete factorizations. Asynchronous algorithms, with their ability to tolerate memory latency, form an important class of algorithms for modern computer architectures. Our GPU implementation considers several non-traditional techniques that can be important for asynchronous algorithms to optimize c...

Tyrosine phosphorylation of the substrate domain of Cas (CasSD) correlates with increased cell migration in healthy and diseased cells. Here we address the mechanism leading to CasSD phosphorylation in the context of fibronectin-induced early spreading of fibroblasts. We previously demonstrated that mechanical stretching of CasSD exposes phosphorylation sites for Src family kinases (SFKs). Surp...

Background: Carotid artery stenting (CAS) has recently been recommended as an alternative to carotid endarterectomy (CEA) by some clinicians. Objective: This study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in Iran for CAS with protection devices, to document our results and guide further use of CAS. Methods: From December 2...

Assume that n tasks must be processed by one machine in a fixed sequence. The processing time, the preferred starting time and the earliness and tardiness costs per time unit are known for each task. The problem is to allocate each task a starting time such that the total cost incurred by the early and tardy tasks is minimum. Garey et al. have proposed a nice O(n log n) algorithm for the specia...

In recent years several dwarf galaxies belonging to the highly obscuredMaffei–IC 342grouphave been discovered. Due to its shape, colour and the presence of a few possible H ii regions, one of these objects (` = 129. ◦6, b = +7. ◦1) was suspected to be a dwarf irregular galaxy, named Cas 1. We have obtained optical spectra of the brightest H ii candidate in Cas 1. By using the Hα/Hβ emission lin...

ID = {x ∈ IR/||x|| < 1} où cette fois on pose ds = |dx 2| (1− ||x||2)2 . Dans les deux cas on note d la distance hyperbolique sur IH. Le bord à l’infini ∂IH s’identifie, selon le modèle choisi, à C ou à S ; dans ce dernier cas, le bord ∂IH est muni de la métrique euclidienne |.|. Dans la suite on fixe une origine o dans IH ; c’est le centre de la boule ID dans le modèle du disque et le point (0...
