Glucose regulation and physical performance among older people: the Helsinki Birth Cohort Study
2018
Aims To assess whether disturbances in glucose regulation are associated with impairment in physical performance during a 10-year follow-up. Methods 475 Men and 603 women from the Helsinki Birth Cohort Study were studied. Glucose regulation was evaluated with a 2-h 75-g oral glucose tolerance test (OGTT) in 2001-2004. Subjects were categorised as having either impaired fasting glucose (IFG), impaired glucose tolerance (IGT), newly diagnosed diabetes or previously known diabetes. Physical performance was assessed approximately 10 years later using the validated senior fitness test (SFT). The relationship between glucose regulation and the overall SFT score was estimated using multiple linear…
Griffonianone D, an isoflavone with anti-inflammatory activity from the root bark of Millettia griffoniana.
2003
A new isoflavone, griffonianone D (1), and the previously known compounds durmillone and odorantin were isolated from a chloroform extract of the root bark of Millettia griffoniana. The structure of 1 was established as (7E)-(6",7"-dihydroxy-3",7"-dimethyloct-2"-enyl)oxy-4'-methoxyisoflavone on the basis of its spectral data. The chloroform extract of the root bark of M. griffoniana and compound 1 showed anti-inflammatory effects in different experimental models of inflammation.
GEOLOGIA DE LAS MARGENES DE LA PLACA DEL CARIBE: GENERALIDADES EN GUATEMALA, COSTA RICA, LA ESPAÑOLA Y RESULTADOS PRELIMINARES DEL ANALISIS DE UNA TR…
2011
The Caribbean Plate margins are constituted by deformed belts built up since the Cretaceous in acompressional and strike-slip stress field, which allowed overthrusting of the Caribbean crust onto the Pacific,North and South American Plates.The Caribbean borders include Jurassic-Cretaceous ophiolitic units (Great Antilles, Venezuela, Costa Rica,Guatemala, etc.), composed by mantle peridotites, gabbros, volcanic and sedimentary covers, which have beendeformed in at least two ductile penetrative phases and were often metamorphosed in the prehnite-pumpelleyite,green and blue schist, amphibolite, and in places eclogite facies. These units may present part of a subductioncomplex or are an accreti…
La confrontación partidista española a propósito de América Latina
2021
América Latina ha sido desde siempre objeto de controversia en España, aunque últimamente con mayor intensidad se ha convertido en materia de utilización partidista, especialmente por parte de un bloque conservador que se esfuerza en convertir hechos y procesos latinoamericanos en elementos de confrontación política interna española. También las izquierdas hispanas tienen presente a América latina en su acción política, y padecen una elevada desinformación, mientras mantienen clichés de otra época. El artículo atiende a tres casos en la confrontación derecha/izquierda de los últimos tiempos: Venezuela, ariete conservador contra el Gobierno de Pedro Sánchez; México, como excitante del nacion…
Constitutional developments in Latin American abortion law.
2016
Abstract For most of the 20th Century, restrictive abortion laws were in place in continental Latin America. In recent years, reforms have caused a liberalizing shift, supported by constitutional decisions of the countries’ high courts. The present article offers an overview of the turn toward more liberal rules and the resolution of abortion disputes by reference to national constitutions. For such purpose, the main legal changes of abortion laws in the last decade are first surveyed. Landmark decisions of the high courts of Argentina, Bolivia, Colombia, and Mexico are then analyzed. It is shown that courts have accepted the need to balance interests and competing rights to ground less res…

Fast prototyping of a SoC-based smart-camera: a real-time fall detection case study
2014
International audience; Smart camera, i.e. cameras that are able to acquire and process images in real-time, is a typical example of the new embedded computer vision systems. A key example of application is automatic fall detection, which can be useful for helping elderly people in daily life. In this paper, we propose a methodology for development and fast-prototyping of a fall detection system based on such a smart camera, which allows to reduce the development time compared to standard approaches. Founded on a supervised classification approach, we propose a HW/SW implementation to detect falls in a home environment using a single camera and an optimized descriptor adapted to real-time t…

Borges: de la metáfora del Libro–mundo a la construcción de un espacio topológico
2013
En el caso de Galileo la metafora del Libro-mundo servia para afirmar, con la propia potencia disruptiva, el intento de codificar una nueva concepcion de la ciencia y de la naturaleza. Una nueva vision del mundo se afirmaba mediante la oposicion entre la lectura directa del libro de la naturaleza y la indirecta, representada por los libros de Aristoteles. Borges utiliza la misma metafora que Galileo para denunciar la falsa transparencia de los mecanismos subyacentes al mismo Cosmos galileano y representar la duda ontologica que de el deriva. La oscilacion continua entre realidad, ficcion y sueno, tipica de toda la produccion borgeana - desde la poesia hasta los ensayos, desde los relatos ha…
Macedonio Fernandez: Vision Pura e istante eterno
2013
Il complesso percorso che conduce ad uno sguardo puro sui misteri del mondo si può realizzare, secondo Macedonio Fernández, attraverso uno sforzo dissociativo, mirato al raggiungimento di una percezione depurata dalle reminiscenze dell’appercezione. Questo tortuoso processo prende il nome di contemplación. Si tratta di un indagine critica sulla natura delle nostre percezioni, finalizzata alla confutazione delle nozioni dell’Io, della Materia, dello Spazio e del Tempo. Solamente dopo quest’analisi critica si potrà raggiungere lo ‘stato mistico’ che Macedonio definisce «ser el mundo sin sujeto ni objeto» o «la actitud de existir sin el yo». La Visión Pura alla quale Macedonio Fernández aspira…
