Effect of metabolic syndrome and of its individual components on renal function of patients with type 2 diabetes mellitus

The objective of this study was to evaluate the effect of metabolic syndrome (MetS) and its individual components on the renal function of patients with type 2 diabetes mellitus (DM). A cross-sectional study was performed in 842 type 2 DM patients. A clinical and laboratory evaluation, including estimated glomerular filtration rate (eGFR) calculated by the modification of diet in renal disease formula, was performed. MetS was defined according to National Cholesterol Education Program - Adult Treatment Panel III criteria. Mean patient age was 57.9 ± 10.1 years and 313 (37.2%) patients were males. MetS was detected in 662 (78.6%) patients. A progressive reduction in eGFR was observed as the number of individual MetS components increased (one: 98.2 ± 30.8; two: 92.9 ± 28.1; three: 84.0 ± 25.1; four: 83.8 ± 28.5, and five: 79.0 ± 23.0; P < 0.001). MetS increased the risk for low eGFR (<60 mL·min-1·1.73 (m²)-1) 2.82-fold (95%CI = 1.55-5.12, P < 0.001). Hypertension (OR = 2.2, 95%CI = 1.39-3.49, P = 0.001) and hypertriglyceridemia (OR = 1.62, 95%CI = 1.19-2.20, P = 0.002) were the individual components with the strongest associations with low eGFR. In conclusion, there is an association between MetS and the reduction of eGFR in patients with type 2 DM, with hypertension and hypertriglyceridemia being the most important contributors in this sample. Interventional studies should be conducted to determine if treatment of MetS can prevent renal failure in type 2 DM patients.

Motivation and Vocabulary Breadth in CLIL and EFL Contexts. Different age, Same Time of Exposure

Numerous studies have found a positive connection between learners’ motivation towards foreign language and foreign language achievement. The present study examines the role of motivation in receptive vocabulary breadth (size) of two groups of Spanish learners of different ages, but all with 734 hours of instruction in English as a Foreign Language (EFL): a CLIL (Content and Language Integrated Learning) group in primary education and a non-CLIL (or EFL) group in secondary education. Most students in both groups were found to be highly motivated. The primary CLIL group slightly overcame the secondary non-CLIL group with respect to the mean general motivation but this is a non-significant difference. The secondary group surpass significantly the primary group in receptive vocabulary size. No relationship between the receptive vocabulary knowledge and general motivation is found in the primary CLIL group. On the other hand, a positive significant connection, although a very small one, is identified for the secondary non-CLIL group. We will discuss on the type of test, the age of students and the type of instruction as variables that could be influencing the results.

VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way

We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey will take 1929 h of observations with the 4-m VISTA telescope during 5 years (2010-2014), covering similar to 10(9) point sources across an area of 520 deg(2), including 33 known globular clusters and similar to 350 open clusters. The final product will be a deep near-IR atlas in five passbands (0.9-2.5 mu m) and a catalogue of more than 106 variable point sources. Unlike single-epoch surveys that, in most cases, only produce 2-D maps, the VVV variable star survey will enable the construction of a 3-D map of the surveyed region using well-understood distance indicators such as RR Lyrae stars, and Cepheids. It will yield important information on the ages of the populations. The observations will be combined with data from MACHO, OGLE, EROS, VST, Spitzer, HST, Chandra, INTEGRAL, WISE, Fermi LAT, XMM-Newton, GAIA and ALMA for a complete understanding of the variable sources in the inner Milky Way. This public survey will provide data available to the whole community and therefore will enable further studies of the history of the Milky Way, its globular cluster evolution, and the population census of the Galactic Bulge and center, as well as the investigations of the star forming regions in the disk. The combined variable star catalogues will have important implications for theoretical investigations of pulsation properties of stars. (C) 2009 Elsevier B.V. All rights reserved.

Procesos configurativos: de la trama a la noción de campo en los "mat buildings"

La presente tesis aborda el estudio sobre los llamados mat buildings, que surgen entre los años cincuenta y sesenta del pasado siglo. Los mat buildings, también llamados “edificios esteras” o “edificios alfombras”, nacen en gran parte como consecuencia de los desacuerdos e insatisfacciones de los CIAM con el reduccionismo funcionalista y los principios de compartimentación funcional. Estos nuevos modelos remplazan el modelo de ciudad entendido como una colección de edificios individuales por una concepción de un patrón urbano. No es la suma de la longitud, la altura y el ancho sino más bien una densa alfombra bi-dimensional, con una configuración de formas que ofrece al mismo tiempo un orden repetitivo y una infinita diversidad de secuencias con infinitas posibilidades de adaptación donde el hombre vive y se desplaza. Estas características que irán apareciendo en la obras de muchos de los arquitectos que forman parte del grupo Team X son los que Alison Smithson empieza a revelar en su artículo, con la ambición de manifestar una nueva sensibilidad y una nueva forma de entender y ver la arquitectura. Los mat buildings y los cluster serán los códigos utilizados por diferentes miembros del Team X para pensar una arquitectura y un urbanismo alternativo al propuesto por los CIAM. Mediante ellos encuentran el camino para una nueva estética de la conexión con un desplazamiento desde una concepción determinista de la forma arquitectónica (una forma cerrada y en general definida a priori) hacia una actitud más libre, más abierta, fundamentada no tanto en la entereza de la forma global sino en cuanto a la intensidad de sus redes internas y de sus diferentes niveles de asociación. La tesis tiene como propósito final cuestionar si esta tipología de edificios, cuyo principio de base es siempre una matriz geométrica abierta (trama, retícula, malla), con crecimiento ilimitado, puede redefinir la frontera entre ciudad y edificio y, por tanto, entre público y privado, individual y colectivo, estructural e infraestructural, permanente y variable. Por ello, se presenta un estudio histórico y crítico en profundidad sobre los mat buildings, analizando detenidamente y por orden cronológico cinco de sus obras más paradigmáticas: el Orfanato en Ámsterdam de Aldo Van Eyck, la Universidad Libre en Berlín de Candilis, Josic y Woods, el Hospital de Venecia de Le Corbusier y Guillermo Jullián de la Fuente, el edificio administrativo de la Centraal Beheer en Apeldoorn de Herman Hertzberger, y por último el MUSAC en León, realizado por Mansilla y Tuñon. Las cuatro primeras obras pertenecen al periodo Team X y son precursoras de muchos otros proyectos que aparecerán a posteriori. La última obra analizada, el MUSAC, es estudiada conjuntamente con algunas obras del arquitecto japonés Sou Fujimoto y otros casos contemporáneos con la intención de manifestar cómo arquitectos de horizontes muy diferentes vuelven a recurrir a estos modelos de crecimientos ilimitados. Mediante el estudio de varios ejemplos contemporáneos se examinan las repercusiones, transformaciones y evoluciones que estos modelos han tenido. La exploración contrastada permite apreciar adecuadamente la pertinencia de estos modelos y los cambios de modalidades y de procesos que advienen con la aparición en el panorama contemporáneo de la noción de campo y los cambios de paradigma que conlleva. Estos nuevos modelos abren nuevos procesos y forma de abordar la arquitectura basada en las relaciones, flujos, movimientos y asociaciones que son caracterizados por diferentes patrones que vienen a alimentar todo el proceso del proyecto arquitectónico. El estudio de estos nuevos modelos nos indica las cualidades que puede ofrecer la revisión de estos métodos para empezar a tratar nuevas cuestiones que hoy en día parecen ser, permanentemente, parte de la condición urbana. XII ABSTRACT This thesis deals with the study of the so-called mat buildings which emerged between the fifties and sixties of the last century. Mat, or carpet, buildings appeared largely as a result of the CIAM’s disagreement and dissatisfaction with functionalist reductionism and the principles of functional compartmentalisation. These new models replaced the model of the city, seen as a collection of individual buildings, with the concept of an urban pattern. It is not the sum of the length, height and width but rather a dense, two- dimensional mat with a configuration of forms offering both a repetitive order and an infinite diversity of sequences with endless possibilities for adaptation, where man lives and circulates. These characteristics, which appeared in the works of many of the architects who formed part of Team X, are those that Alison Smithson started to reveal in her article with the aim of manifesting a new sensibility and a new way of understanding and seeing architecture. Mat buildings and clusters were the codes used by different members of Team X to plan an alternative architecture and urbanism to that proposed by the CIAM. With them, they found the path for a new aesthetic of connection, with a shift from a deterministic concept of the architectural form (closed and generally defined a priori) towards a more free, more open attitude based not so much on the integrity of the overall form but on the intensity of its internal networks and different levels of association. The end purpose of this thesis is to question whether this type of building, the basic principle of which is always an open geometric matrix (grid, recticle, network) with unlimited growth, can redefine the boundary between city and building and, thus, between public and private, individual and collective, structural and infrastructural, and permanent and variable. To this end, an in-depth historical and critical study of mat buildings is presented, analysing carefully and in chronological order five of the most paradigmatic works of this style: the Orphanage in Amsterdam, by Aldo Van Eyck; the Free University of Berlin, by Candilis, Josic and Woods; Venice Hospital, by Le Corbusier and Guillermo Jullián de la Fuente; the Centraal Beheer administration building in Apeldoorn, by Herman Hertzberger; and lastly, the MUSAC (Contemporary Art Museum) in León, designed by Mansilla and Tuñon. The first four works are from the Team X period and were the precursors to many other projects that would appear later. The last work analysed, the MUSAC, is studied together with some works by Japanese architect Sou Fujimoto and other contemporary cases to show how architects with very different perspectives revert to these models of limitless growth. Through the study of several contemporary examples we examine the repercussions, transformations and evolutions these models have had. The contrasted research XIII allows us to properly appreciate the importance of these models and the changes in forms and processes that came with the emergence of the idea of field in the contemporary arena and the paradigm shifts it entailed. These new models opened up new processes and a way of approaching architecture based on relationships, flows, movements and associations characterised by different patterns that feed the entire process of the architectural project. The study of these new models shows us the benefits that a review of these methods can contribute to addressing new issues that today appear to be a permanent part of the urban condition.

How can an invasive grass affect fire behavior in a tropical savanna? A community and individual plant level approach

Some invasive grasses have been reported to change fire behavior in invaded plant communities. Urochloa brizantha is an aggressive invasive grass in the Brazilian Cerrado, an ecosystem where fire is a common disturbance. We investigated the effects of U. brizantha on fire behavior in an open Cerrado physiognomy in Central Brazil. Using experimental burnings we compared fire behavior at both the community and the individual plant level in invaded (UJ) and non-invaded (NJ) areas burned in July. We also assessed the effect of fire season in invaded areas by comparing July (UJ) and October (UO) burnings. We evaluated the following variables: fuel load, fuel moisture, combustion efficiency, maximum fire temperature, flame height, and fire intensity. Additionally, we evaluated the temperatures reached under invasive and native grass tussocks in both seasons. Fuel load, combustion efficiency, and fire intensity were higher in NJ than in UJ, whilst flame height showed the opposite trend. Fuel amount and fire intensity were higher in October than in July. At the individual plant level, U. brizantha moisture was higher than that of native species, however, temperatures reaching ≥600 °C at ground level were more frequent under U. brizantha tussocks than under native grasses. At the community level, the invasive grass modified fire behavior towards lower intensity, lower burning efficiency, and higher flame height. These results provide essential information for the planning of prescribed burnings in invaded Cerrado areas.

Season-Long Examination of the Intervention Tone of Coach-Athlete Interactions and Athlete Development in Youth Sport

Objectives: Coaches are a primary influence on athletes' development in youth sport (Horn, 2008). However, the intervention tone of coaches' behaviour has not been directly observed. The purpose of this study was to examine associations between the intervention tone exhibited by youth sport coaches and athletes' individual developmental trajectories over the course of a season. Design: Short-term longitudinal study with behavioural observation. Method: Fifty-five athletes and their coaches from five youth volleyball teams were observed at three time points, and the intervention tone of interactive behaviour was systematically coded and organized by coach-athlete dyad. Athletes completed measures of the 4C's of athlete development (competence, confidence, connection, character) at each time point, which were used to create individualized developmental trajectories. Person-centred analyses were used to examine associations between athletes' developmental trajectories and their unique interactive experiences with their coach. Results: Cluster analysis revealed the presence of three distinct clusters based on athletes' developmental trajectories: 1) high and increasing, 2) low and decreasing, and 3) moderate and maintaining, with athletes from each team distributed across clusters. Analysis of dyadic interaction profiles revealed significant differences in interactive behaviour between clusters. Conclusions: Results suggest that differences in coach-athlete interactive experiences are associated with different developmental trajectories over the course of a season, even for athletes working with the same coach, highlighting the individualized nature of coaches' influence on young athletes. Practical implications for coaches include a critical awareness of their unique interactive relationship with each athlete independently, as well as the importance of fostering these relationships with regard to young people as more than just athletes.

Patterns of acculturative stress: Continuity, discontinuity, and adjustment among Latino youth

This study evaluated inter- and intra-individual changes in acculturation, acculturative stress, and adaptation experiences, as well as their associations with adjustment outcomes among a group of Latino adolescents in South Florida. Specifically, the current study investigated the incidence, changes, and effects of stressors that arise from acculturation experiences (e.g., related to culture, discrimination, language difficulties) among Latino youth by employing a person-centered approach and a longitudinal research design. Four separate groups of analyses were conducted to investigate (a) within-group differences in levels of reported acculturative stress, (b) patterns of continuity and discontinuity in levels of acculturative stress across time, (c) adjustment outcomes associated with distinct patterns of acculturative stress within each measurement occasion, and (d) predictive relations between longitudinal acculturative stress trajectories in early adolescence and psychosocial adjustment outcomes in young adulthood. ^ Results from the multivariate analyses indicated great within group heterogeneity in acculturative stress among Latino youth during early adolescence, as well as significant continuity and discontinuity in the patterns of shifts among acculturative stress profiles between contiguous measurement occasions. Within each developmental period, membership in acculturative stress clusters was significantly and differentially associated with multiple adjustment outcomes, suggesting that maladaptive outcomes are more likely to occur among Latino adolescents experiencing high levels of psychological distress across multiple acculturative domains. In general, Latino youth acculturation is best understood as multi-dimensional, to be variable across time, and to be fluid and responsive to multiple factors and influences. Implications for preventive strategies are discussed with regard to acculturation and developmental psychology research literatures. ^

Lack of effect of lowering LDL cholesterol on cancer: meta-analysis of individual data from 175,000 people in 27 randomised trials of statin therapy

Background: Statin therapy reduces the risk of occlusive vascular events, but uncertainty remains about potential effects on cancer. We sought to provide a detailed assessment of any effects on cancer of lowering LDL cholesterol (LDL-C) with a statin using individual patient records from 175,000 patients in 27 large-scale statin trials. Methods and Findings: Individual records of 134,537 participants in 22 randomised trials of statin versus control (median duration 4.8 years) and 39,612 participants in 5 trials of more intensive versus less intensive statin therapy (median duration 5.1 years) were obtained. Reducing LDL-C with a statin for about 5 years had no effect on newly diagnosed cancer or on death from such cancers in either the trials of statin versus control (cancer incidence: 3755 [1.4% per year [py]] versus 3738 [1.4% py], RR 1.00 [95% CI 0.96-1.05]; cancer mortality: 1365 [0.5% py] versus 1358 [0.5% py], RR 1.00 [95% CI 0.93-1.08]) or in the trials of more versus less statin (cancer incidence: 1466 [1.6% py] vs 1472 [1.6% py], RR 1.00 [95% CI 0.93-1.07]; cancer mortality: 447 [0.5% py] versus 481 [0.5% py], RR 0.93 [95% CI 0.82-1.06]). Moreover, there was no evidence of any effect of reducing LDL-C with statin therapy on cancer incidence or mortality at any of 23 individual categories of sites, with increasing years of treatment, for any individual statin, or in any given subgroup. In particular, among individuals with low baseline LDL-C (<2 mmol/L), there was no evidence that further LDL-C reduction (from about 1.7 to 1.3 mmol/L) increased cancer risk (381 [1.6% py] versus 408 [1.7% py]; RR 0.92 [99% CI 0.76-1.10]). Conclusions: In 27 randomised trials, a median of five years of statin therapy had no effect on the incidence of, or mortality from, any type of cancer (or the aggregate of all cancer).

Fossil associations from the middle and upper Eocene strata of the Pamplona Basin and surrounding areas (Navarre, western Pyrenees)

Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral foreland basin and extends from deep-marine turbiditic (Ezkaba Sandstone Formation) to deltaic (Pamplona Marl, Ardanatz Sandstone and Ilundain Marl formations) and marginal marine deposits (Gendulain Formation). The micropalaeontological content is high. It is dominated by foraminifera, and common ostracods and other microfossils are also present. The fossil ichnoasssemblages include at least 23 ichnogenera and 28 ichnospecies indicative of Nereites, Cruziana, Glossifungites and ?Scoyenia-Mermia ichnofacies. Body macrofossils of 78 taxa corresponding to macroforaminifera, sponges, corals, bryozoans, brachiopods, annelids, molluscs, arthropods, echinoderms and vertebrates have been identified. Both the number of ichnotaxa and of species (e. g. bryozoans, molluscs and condrichthyans) may be considerably higher. Body fossil assemblages are comparable to those from the Eocene of the Nord Pyrenean area (Basque Coast), and also to those from the Eocene of the west-central and eastern part of South Pyrenean area (Aragon and Catalonia). At the European scale, the molluscs assemblages seem endemic from the Pyrenean area, although several Tethyan (Italy and Alps) and Northern elements (Paris basin and Normandy) have been recorded. Palaeontological data of studied sedimentary units fit well with the shallowing process that throughout the middle and late Eocene occurs in the area, according to the sedimentological and stratigraphical data.

Strontium isotopes and sedimentology of a marine Triassic succession (upper Ladinian) of the westernmost Tethys, Spain

Chemical Stratigraphy, or the study of the variation of chemical elements within sedimentary sequences, has gradually become an experienced tool in the research and correlation of global geologic events. In this paper 87Sr/ 86Sr ratios of the Triassic marine carbonates (Muschelkalk facies) of southeast Iberian Ranges, Iberian Peninsula, are presented and the representative Sr-isotopic curve constructed for the upper Ladinian interval. The studied stratigraphic succession is 102 meters thick, continuous, and well preserved. Previous paleontological data from macro and micro, ammonites, bivalves, foraminifera, conodonts and palynological assemblages, suggest a Fassanian-Longobardian age (Late Ladinian). Although diagenetic minerals are present in small amounts, the elemental data content of bulk carbonate samples, especially Sr contents, show a major variation that probably reflects palaeoenvironmental changes. The 87Sr/86Sr ratios curve shows a rise from 0.707649 near the base of the section to 0.707741 and then declines rapidly to 0.707624, with a final values rise up to 0.70787 in the upper part. The data up to meter 80 in the studied succession is broadly concurrent with 87Sr/86Sr ratios of sequences of similar age and complements these data. Moreover, the sequence stratigraphic framework and its key surfaces, which are difficult to be recognised just based in the facies analysis, are characterised by combining variations of the Ca, Mg, Mn, Sr and CaCO3 contents

This review shows an overview of current and future applications of nanotechnology in the food industry. Food additives and materials in contact with food are now the main applications, while it is expected that in the future are in the field of nano-encapsulated and nanocomposites in applications as novel foods, additives, biocides, pesticides and materials food contact.

Social economy, youth and employment

Organizations of the Social Economy in Spain accounted for 13% of employment and 12% of GDP in 2013, according to the Spanish Confederation fo Social Economy. Also, according to various institutions and studies, the role of Social Economy has become relevant due to they represent a model promoting the creation of collective business projects with greater sustainability and potential than models of individual self-employment. However, despite all this, there are few academic studies or sectoral reports analyzing employment in this sector, especially in the case of youth employment. This study aims to fill this gap in the literature analyzing the scared available data in order to show the numbers and characteristics of youth employment in this sector. Results show the weight of youth employment in the Social Economy is higher than the economy overall.
