Spain in Europe 2004-2008

In March of 2004, the Observatory of European Foreign Policy published a special monograph about Spain in Europe (1996-2004) in digital format. The objective of the monograph was to analyse Spain’s foreign policy agenda and strategy during the period of José María Aznar’s presidency. As the title suggests, one of the initial suppositions of the analysis is the Europeanization of Spanish foreign activities. Is that how it was? Did Aznar’s Spain see the world and relate to it through Brussels? The publication was well received, considering the number of visits received and above all the institutions which asked to link the publication to their web pages. Among these, the EUobserver published the introduction to the piece in English titled Aznar: thinking locally, acting in Europe (described by the EUobserver as a paper of utmost importance). The fact that the elections were held three days after the tragic events of the 11th of March dramatically increased interest in Spain and the implications for Europe. This publication is the second of its type, in this case analysing the period of the Zapatero government (2004-2008). Once again the starting premise (the Europeanization of the agenda and the methods employed) has been considered by the analysts. And once again the articles collected in this publication serve to “triangulate” the analysis. Spain and Europe are two vertices (more or less distant, in essence and in form) which the authors handle in their analysis of the case (third vertex).

España en Europa 2004-2008

En marzo de 2004 el Observatorio de Política Exterior Europea publicó, en versión digital, un monográfico especial sobre España en Europa (1996-2004). Su objetivo era analizar la agenda y la estrategia de España durante el período de José María Aznar en materia de relaciones internacionales. Como bien indicaba el título de aquella publicación, uno de los supuestos de partida del análisis era la europeización de la actividad internacional de España. ¿Era así?, ¿la España de Aznar veía el mundo y se aproximaba a él a través de Bruselas? Aquella publicación tuvo una buena acogida, a la vista de las visitas recibidas y sobre todo de las instituciones que nos pidieron vincular dicha publicación a sus páginas web y, entre ellas, hay que destacar que EUObserver publicó como comentario su artículo introductorio, en versión inglesa, Aznar: thinking locally, acting in Europe (calificado por EUObserver como lectura de máxima relevancia). El hecho de que las elecciones de 2004 se celebraran tres días después de los trágicos acontecimientos del 11-M hizo que el interés por España y por su proyección europea e internacional aumentara de manera destacada. La presente publicación constituye un segundo ejercicio de dicho tipo, en este caso para analizar el período del gobierno Zapatero (2004-2008). Una vez más, el supuesto de partida (la europeización de la agenda y del método) está en la mente de los analistas. Y una vez más los artículos recogidos en esta publicación hacen el ejercicio de “triangular” el análisis. España y Europa son dos vértices (más o menos alejados, en el fondo y en la forma) que los autores manejan en sus análisis de caso (tercer vértice)

La polémica identidad de los valencianos: a propósito de las reformas de los Estatutos de Autonomía

La cuestión de las nacionalidades se ha reabierto en España al calor de las reformas de los Estatutos de Autonomía impulsadas por el gobierno socialista de José Luís Rodríguez Zapatero. Sin embargo, no todas las reformas emprendidas por las Comunidades Autónomas han reivindicado el mismo tratamiento identitario en sus Estatutos. Este trabajo pretende ofrecer alguna luz, desde la ciencia política, para explicar el diferente curso identitario que caracteriza a la Comunidad Valenciana en relación a otras comunidades, como es el caso de Cataluña o Andalucía. A tal fin se exponen los modelos de autopercepción identitaria y su distribución o anclaje entre los valencianos, junto con el análisis de la repercusión de esta dimensión en términos electorales. Esos datos permiten al autor sugerir algunas explicaciones sobre el pacto estatutario alcanzado en torno a la identidad de los valencianos y sobre el comportamiento de los principales actores políticos valencianos en el proceso de reforma estatutaria de 2006.

Propietats protectores de la lipoproteïna de alta densitat (HDL) sobre l'acció inflamatòria de la lipoproteïna de baixa densitat electronegativa (LDL(-)) en monòcits humans

Electronegative low-density lipoprotein (LDL(-)) is a modified fraction of LDL present in peripheral blood whose proportion is elevated in subjects with increased cardiovascular risk. LDL(-) has been shown to have an inflammatory effect on human endothelial cells and mononuclear blood cells. On the other hand, high-density lipoprotein (HDL) is known to have a protective effect against cardiovascular disease, partly mediated by its anti-inflammatory properties. The objective of the current work is to study the putative protective properties of HDL towards the inflammatory effect of LDL(-) in human monocytes, in order to elucidate the mechanisms behind their interaction. Total LDL and HDL were isolated by ultracentrifugation and LDL(-) was obtained from total LDL by anion exchange chromatography. HDL and LDL(-) were incubated together and then re-isolated, and their characteristics were compared to those of untreated lipoproteins. The inflammatory activity of the lipoproteins was determined by incubating monocytes with lipoproteins and measuring cytokine release from the cultured monocytes. The biochemical composition and electrophoretic mobility of the lipoproteins were also determined before and after their interaction. Incubation of HDL with LDL(-) reduced the inflammatory effect of LDL(-) and, in turn, HDL gained inflammatory properties. This indicates a transfer of inflammatory potential taking place during the interaction of LDL(-) and HDL. Additionally, LDL(-) lost non-esterified fatty acids (NEFAs) while HDL gained the same. We conclude that a transfer of NEFAs takes place between LDL(-) and HDL. These observations suggest that NEFAs play a role in the inflammatory effect mediated by LDL(-).

The Effect of a Physical Activity Program on the Total Number of Primary Care Visits in Inactive Patients: A 15-Month Randomized Controlled Trial

Abstract Background: Effective promotion of exercise could result in substantial savings in healthcare cost expenses in terms of direct medical costs, such as the number of medical appointments. However, this is hampered by our limited knowledge of how to achieve sustained increases in physical activity. Objectives: To assess the effectiveness of a Primary Health Care (PHC) based physical activity program in reducing the total number of visits to the healthcare center among inactive patients, over a 15-month period. Research Design: Randomized controlled trial. Subjects: Three hundred and sixty-two (n = 362) inactive patients suffering from at least one chronic condition were included. One hundred and eighty-three patients (n = 183; mean (SD); 68.3 (8.8) years; 118 women) were randomly allocated to the physical activity program (IG). One hundred and seventy-nine patients (n = 179; 67.2 (9.1) years; 106 women) were allocated to the control group (CG). The IG went through a three-month standardized physical activity program led by physical activity specialists and linked to community resources. Measures: The total number of medical appointments to the PHC, during twelve months before and after the program, was registered. Self-reported health status (SF-12 version 2) was assessed at baseline (month 0), at the end of the intervention (month 3), and at 12 months follow-up after the end of the intervention (month 15). Results: The IG had a significantly reduced number of visits during the 12 months after the intervention: 14.8 (8.5). The CG remained about the same: 18.2 (11.1) (P = .002). Conclusions: Our findings indicate that a 3-month physical activity program linked to community resources is a shortduration, effective and sustainable intervention in inactive patients to decrease rates of PHC visits.

Conserved developmental expression of Fezf in chordates and Drosophila and the origin of the Zona Limitans Intrathalamica (ZLI) brain organizer

Background: The zona limitans intrathalamica (ZLI) and the isthmus organizer (IsO) are two major secondary organizers of vertebrate brain development. These organizers are located at the interface of the expression domains of key patterning genes (Fezf-Irx and Otx-Gbx, respectively). To gain insights into the evolutionary origin of the ZLI, we studied Fezf in bilaterians. Results: In this paper, we identified a conserved sequence motif (Fezf box) in all bilaterians. We report the expression pattern of Fezf in amphioxus and Drosophila and compare it with those of Gbx, Otx and Irx. We found that the relative expression patterns of these genes in vertebrates are fully conserved in amphioxus and flies, indicating that the genetic subdivisions defining the location of both secondary organizers in early vertebrate brain development were probably present in the last common ancestor of extant bilaterians. However, in contrast to vertebrates, we found that Irx-defective flies do not show an affected Fezf expression pattern. Conclusions: The absence of expression of the corresponding morphogens from cells at these conserved genetic boundaries in invertebrates suggests that the organizing properties might have evolved specifically in the vertebrate lineage by the recruitment of key morphogens to these conserved genetic locations.
