Premedication with oral solution of simethicone plus N-acetylcysteine to improve the quality upper GI endoscopy: Initial experience
2020
Introduction: To assess the efficacy and safety of simethicone with or without N-acetylcysteine (NAC) as premedications before gastroscopy. Materials and methods: Patients were randomized into 5 groups. Endoscopic visibility was evaluated in 4 districts (esophagus, gastric body, fundus and antrum) using a visual scale, graduating from 1 to 4 points. Results: There was no significant difference on the rate of positive findings when comparing simethicone with simethicone plus NAC and with water, respectively. Simethicone plus NAC showed better total mucosal visibility score than simethicone alone. Both simethicone plus NAC and simethicone alone offer more benefit than water. The procedure tim…
A homozygous mutation in the TUB gene associated with retinal dystrophy and obesity.
2013
Inherited retinal dystrophies are a major cause of childhood blindness. Here, we describe the identification of a homozygous frameshift mutation (c.1194_1195delAG, p.Arg398Serfs*9) in TUB in a child from a consanguineous UK Caucasian family investigated using autozygosity mapping and whole-exome sequencing. The proband presented with obesity, night blindness, decreased visual acuity, and electrophysiological features of a rod cone dystrophy. The mutation was also found in two of the proband's siblings with retinal dystrophy and resulted in mislocalization of the truncated protein. In contrast to known forms of retinal dystrophy, including those caused by mutations in the tubby-like protein …
New preparation of ceramic coatings by low-pressure plasma spray
2018
As an advanced thermal spray technology, low-pressure plasma spray (LPPS) allows obtaining high-quality coatings and can bridge the thickness gap between conventional thermal spray technologies and standard thin film processes. Moreover, LPPS permits to build uniform coatings with various microstructures; deposition takes place not only from liquid splats but also from nano-sized clusters as well as from the vapor phase depending on operational conditions. In order to further improve and develop the LPPS process, this research aims to combine it with the emerging suspension plasma spray and reactive plasma spray processes. It was expected to both provide two novel integrated processes and a…
Marco integrador para el estudio de las barreras a la gestión del conocimiento
2006
La Gestión del Conocimiento es una disciplina que surge como consecuencia de la importancia creciente del conocimiento como factor de generación de riqueza en la sociedad, y en particular, en las organizaciones. Las tecnologías de la información y las comunicaciones posibilitan el desarrollo de herramientas que facilitan la captura, almacenamiento, diseminación y reutilización de información contextualizada. Sin embargo, la aplicación de estas tecnologías y los conceptos asociados a esta disciplina están proporcionando resultados inferiores a las expectativas. La literatura esta describiendo la existencia de barreras que inhiben la gestión de este recurso principalmente asociado a las perso…
Granuloma piógeno en tapones lagrimales smart plug
2007
espanolCaso clinico: Mujer de 65 anos, diagnosticada de ojo seco, acude por aparicion de tumoracion en canto interno con sensacion de cuerpo extrano. Tres anos antes se le habian implantado tapones lagrimales SmartPlug en ambos puntos lagrimales inferiores. Se aprecio un granuloma en el punto lagrimal inferior izquierdo que se extirpo. Dos semanas despues presento una recidiva lo que obligo a extraer el implante quedandose desde entonces asintomatica. Discusion: Estamos ante un granuloma piogeno en un implante punctal SMART PLUG, complicacion descrita clasicamente con los implantes de silicona, debido posiblemente a la irritacion cronica de los detritus acumulados. Esta complicacion obliga …
Weighted limits in simplicial homotopy theory
2010
Abstract By combining ideas of homotopical algebra and of enriched category theory, we explain how two classical formulas for homotopy colimits, one arising from the work of Quillen and one arising from the work of Bousfield and Kan, are instances of general formulas for the derived functor of the weighted colimit functor.
Formations of finite monoids and formal languages: Eilenberg’s variety theorem revisited
2014
International audience; We present an extension of Eilenberg's variety theorem, a well-known result connecting algebra to formal languages. We prove that there is a bijective correspondence between formations of finite monoids and certain classes of languages, the formations of languages. Our result permits to treat classes of finite monoids which are not necessarily closed under taking submonoids, contrary to the original theory. We also prove a similar result for ordered monoids.; Nous présentons une extension du théorème des variétés d'Eilenberg, un résultat célèbre reliant l'algèbre à la théorie des langages formels. Nous montrons qu'il existe une correspondance bijective entre les form…
Common fixed points for self mappings on compact metric spaces
2013
In this paper we obtain a result of existence of points of coincidence and of common fixed points for two self mappings on compact metric spaces satisfying a contractive condition of Suzuki type. We also present some examples to illustrate our results. Moreover, using the scalarization method of Du, we deduce a result of common fixed point in compact cone metric spaces.
On a class of compactly epi-Lipschitzian sets
2003
The paper is devoted to the study of the so-called compactly epi-Lipschitzian sets. These sets are needed for many aspects of generalized differentiation, particulary for necessary optimality conditions, stability of mathematical programming problems and calculus rules for subdifferentials and normal cones. We present general conditions under which sets defined by general constraints are compactly epi-Lipschitzian. This allows us to show how the compact epi-Lipschitzness properties behave under set intersections.
Weakly \varphi-pairs and common fixed points in cone metric spaces
2009
In this paper we introduce a weak contractive condition, called weakly \varphi-pair, for two mappings in the framework of cone metric spaces and we prove a theorem which ensures existence and uniqueness of common fixed points for such mappings. Also we obtain a result on points of coincidence. These results extend and generalize well-known comparable results in the literature.
