Provider: - Institution: - Data provided by Europeana Collections- This thesis is devoted to review, assess and validate the potential of dendroarchaeology in the Iberian Peninsula, to define ...strategies for its future development and implementation in this territory, and to illustrate the importance of its application in the study of cultural heritage made of wood. To accomplish these main goals, a review of the current state of dendroarchaeology in the Iberian Peninsula was carried out, together with four pilot projects directed at exploring every aspect covered by dendroarchaeological research. One of these projects consisted on the development of multi-century reference chronologies of black pine (Pin us nigra subsp. saizmannii) at different elevations in the Cazorla and Segura mountains (eastern Andalusia), to explore their suitability as dating and provenancing tools for historic timbers. The other pilot projects illustrate the application of dendroarchaeology to provide, in addition to absolute dates, information about the provenance of the wood, the organisation of timber supply, the transport and trade of timber, and the evolution of wood-working techniques during the Early Modern Period. For this, dendroarchaeological research was carried out on historic buildings (Jaen Cathedral and Colegial dei Salvador church in Seville), selected art-historic objects (Evangelistas altarpiece at Seville cathedral) and shipwrecks (Arade 1 shipwreck, found at the mouth of the Arade river in the south of Portugal, excavated, and later on conserved at the Centro Nacional de Arqueología Náutica e Subaquática, in Lisbon). The results have demonstrated that dendroarchaeological studies have a great potential in the Iberian Peninsula. Wood from historic buildings, art-historic objects and archaeological contexts is abundant in the territory and represents an historic, ethnographical and environmental archive that can be studied by means of dendrochronology. This thesis shows that to achieve a well replicated set of reference chronologies needed for dating cultural heritage from this geographical region, strategies for tree-ring data compilation should be directed at key source areas along elevation, latitudinal and longitudinal gradients, covering all possible environmental niches. To improve the replication of the earlier centuries of those chronologies and extend them back in time, timbers from historic buildings offer the best prospects, although the selection of buildings should be preceded by documentary research, in order to acquire as much information a priori as possible in what regards the origin of the wood. The transport and trade of timber within the peninsula, and specially the import of raw timber and manufactured timber products into Spain and Portugal are questions that can be addressed by dendroarchaeology, as demonstrated in this thesis. They also provide a broader, international dimension to future research lines. Dendroprovenancing studies have a paramount role in this territory, hence multidisciplinary national and international collaboration is required to explore novel, high-resolution approaches to establish the provenance of historic wood. Last but not least, campaigns of awareness about the potential of this discipline to increase our understanding of cultural heritage have proven effective in the short and medium term, but for dendroarchaeology to be fully established in Spain and Portugal, structural support and commitment from national and regional institutes, research centres and academic institutions is essential. Only then will dendroarchaology reach the full potential and high quality standards that have already been acquired in most of northern, central and eastern Europe.- Esta tesis está dedicada a revisar, evaluar y validar el potencial de la dendroarqueología en la Península Ibérica, definir estrategias para su desarrollo y aplicación en el futuro en este territorio, e ilustrar la importancia de su aplicación en el estudio del patrimonio cultural de madera. Para lograr estos objetivos, se ha llevado a cabo una revisión del estado de la cuestión, junto con cuatro proyectos piloto dedicados a explorar todos los aspectos cubiertos por la dendroarqueología. Uno de estos proyectos consistió en el desarrollo de cronologías de referencia de pino salgareño (Pinus nigra subsp. salzmannii) a lo largo de un gradiente altitudinal en las montañas de Cazorla y Segura (Andalucía Oriental), para explorar su idoneidad como herramientas de datación y determinación de procedencia de maderas históricas. Los demás proyectos piloto ilustran la aplicación de la dendroarqueología para proporcionar dataciones absolutas, información sobre la procedencia de la madera, la organización del abastecimiento de este material, el transporte y el comercio, y la evolución de las técnicas de procesado durante la Edad Moderna. Para ello, se llevó a cabo la investigación dendroarqueológica de cubiertas de edificios históricos (Catedral de Jaén y la iglesia Colegial del Salvador, en Sevilla), objetos histórico-artísticos (retablo de los Evangelistas en la catedral de Sevilla) y pecios {Arade 1, encontrado en la desembocadura del río Arade en el sur de Portugal, excavado, y más tarde conservado en el CNANS de Lisboa). Los resultados han demostrado que los estudios dendroarqueológicos tienen un gran potencial en la Península Ibérica. La madera de edificios históricos, obras de arte y contextos arqueológicos abunda en el territorio y representa un archivo histórico, etnográfico y ambiental que puede ser estudiado mediante dendrocronología. Esta tesis demuestra que para lograr un conjunto bien replicado de cronologías de referencia necesario para estudiar patrimonio cultural en esta zona geográfica, estrategias para la compilación de datos deben dirigirse a áreas clave de abastecimiento histórico de madera, seleccionando masas a lo largo de gradientes altitudinales, latitudinales y longitudinales en dichas áreas y cubriendo todos los posibles nichos ambientales. Para mejorar la replicación de los siglos más antiguos de esas cronologías y extenderlas retrospectivamente en el tiempo, maderas de edificios históricos ofrecen las mejores perspectivas, aunque la selección de los edificios debe ir precedida de una investigación documental, con el fin de adquirir la mayor cantidad de información posible a príoríen lo que se refiere al origen de la madera. Esta tesis también ha puesto de manifiesto la posibilidad de estudiar mediante la dendroarqueología cuestiones como el transporte de la madera en los ríos peninsulares, y sobre todo, la importación de productos madereros a España y Portugal, temas que dotan a las futuras líneas de investigación de una dimensión amplia e internacional. En este contexto de transporte y comercio de madera, los estudios de 'dendroprocedencia' tienen gran relevancia en la Península Ibérica, por lo que la colaboración multidisciplinar nacional e internacional adquiere un rol crucial para datar la madera y explorar nuevos métodos que permitan establecer su procedencia con alta resolución geográfica. Campañas de sensibilización sobre el potencial de esta disciplina para aumentar nuestro conocimiento del patrimonio cultural han demostrado ser eficaces a corto y medio plazo. Sin embargo, para asentar la dendroarqueología en España y Portugal y conseguir que su uso sea sistemático, es crucial contar con el apoyo estructural por parte de centros de investigación nacionales y regionales, así como de instituciones académicas. Sólo entonces alcanzará la dendroarqueología en estos países la relevancia, calidad y potencial que ha adquirido ya en la mayor parte del centro, norte y este de Europa.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.

European hake (Merluccius merluccius) is a commercially important resource in Iberian Atlantic waters. Despite the recovery plan implemented in 2006 and the multiannual management plan for western ...waters, fishing mortality is still higher than that corresponding to the maximum sustainable yield for the southern European hake stock. The biological processes underlying the dynamics of this stock and its life history traits are essential for assessing population productivity and resilience, making them basic information for management. We analysed the temporal variability of size at maturity (L50) of this species and the main factors influencing it in Atlantic Iberian waters from 1982 to 2019. The annual variability of L50 for each sex was modelled with generalized additive models, considering explanatory environmental variables (Atlantic Multidecadal Oscillation, North Atlantic Oscillation and sea surface temperature) and biological variables (biomass, spawning biomass at length and relative condition factor). The results showed that the L50 of males decreased by a total of 12.9 cm and L50 of females decreased by a total of 10.9 cm from 1982 to 2019. For females the significant explanatory variables were year, spawning biomass at length, biomass and the North Atlantic Oscillation, while for males only year was an explanatory variable. These results are important for understanding the status of the European hake population, signalling that L50 is a good indicator for predicting future population dynamics.
We present the case of a 35-year-old male with a first-degree family history of gastric cancer (his father was diagnosed at the age of 45), who was presumed to have gastric cancer himself when ...evaluating the features of his upper endoscopy performed after hematemesis. Surprisingly, no cancer cells were found in the biopsies. Thanks to a different diagnostic suspicion subsequent to performing a full clinical history, a more favorable diagnosis was reached: gastric syphilis.
Es investigadora del Centro de Estudios Interdisciplinarios sobre Nuestra América "José Martí" (CEINA); del Centro de Estudios Regionales "Félix Weinberg" (CER); es miembro del Consejo Directivo de ...la Fundación Ezequiel Martínez Estrada e integra la red "El ensayo en diálogo". Está especializada en los ensayos de interpretación de Ezequiel Martínez Estrada, prosa de ideas, pensamiento político, redes e historia intelectual en América Latina. Lo medular del estudio de la doctora Lamoso, quien insumió años de rigurosas investigaciones, es la indagación de los sentidos y alcances de la auto-percepción intelectual del escritor. Su trabajo consiste en definir distintos períodos que implican cambios en lo que respecta a su modo de leer la literatura, el rol social y político de los actores culturales, que vincula con el estudio de autores como Sarmiento. Diferencias y semejanzas entre los países de América Latina, el "Prólogo inútil" de su Antología, así como los discursos publicados en Cuadernos Americanos. El estudio de las redes intelectuales le permitió a la investigadora reinsertar la frondosa y compleja producción ensayística global de Ezequiel Martínez Estrada en el entramado de variados y densos procesos, que lo fueron recolocando en el campo de la cultura latinoamericana, en particular, a partir de los estrechos vínculos mantenidos con los directores sucesivos del Fondo de Cultura Económica de México. Resulta un aporte fundamental verlo, entonces, como un autor en diálogo no sólo intelectual sino editorial y epocal. Asimismo, la reconstrucción de este camino sinuoso pennitirá un posterior estudio de la aún poco explorada "etapa cubana" de Ezequiel Martínez Estrada.
The human papillomavirus (HPV), is necessary to cause a woman developing cervical cancer. The aim of the study was to estimate the prevalence of women with HPV infection, covered by the program of ...prevention and early detection of cervical cancer of Castile and León (Spain).
Samples of women included in the screening program were analyzed. Including a total of 120,326 cervical swab samples, collected in the period from January 2012 to December 2014.
12,183 HPV positive samples were detected, representing a prevalence of 9.6 ‰, (IC 95% 9.5%-9.8%) in the female population. High-risk HPV were found in higher proportion that HPV low-risk genotypes. HPV prevalence correlates inversely with women age. Coinfections of multiple genotypes were found in one third of screened women population.
Data showed in this study are the first and wider Spanish results from a cervical cancer screening program population non opportunistic based on HPV detection. These results would serve as a reference for future prevalence studies and to evaluate the future impact of HPV vaccination campaigns.
ObjectivesCation exchange high-performance liquid chromatography (HPLC) is one of the techniques available for determining glycated hemoglobin (HbA1c) and also the method of choice for structural ...hemoglobinopathies screening. The objective of this case is to show how in a routine HbA1c test it is possible to incidentally find a hemoglobinopathy.Case presentationIn a routine blood analysis, an abnormal value for the hemoglobin A2 (HbA2) was obtained during the study of HbA1c with HPLC on the ADAMS™ A1c HA-8180T. After suspecting it could be due to the presence of a hemoglobinopathy, the study of possible variants was expanded using electrophoresis and HPLC on the Hydrasys and Variant II analysers, respectively. Since it could not be identified by these conventional methods, a genetic study was also carried out using Sanger sequencing. The patient presented a low HbA2 (1.3 %) and a 24.9 % variant with a retention time of 1.95 min, compatible with alpha-globin chain variant. In the genetic study, the pathogenic variant c.138C>G was detected in the HbA2 gene in heterozygosis, which resulted in the expression of the structural hemoglobinopathy known as hemoglobin Bari.ConclusionsThe initial screening for structural hemoglobinopathies allows its identification or suspicion especially when it was performed with HbA1c analysis, requiring subsequent confirmation and diagnosis by other techniques.

Es decir, cómo se pasa de ser ciudades periféricas dependientes de la gran metrópoli a ser ciudades centrales a través de la potenciación de estrategias de identidad local por parte de la política local. Los efectos de dicha exaltación quedan plasmados en la dinámica urbana de forma que podemos constatar la participación de ciertos sectores sociales y la desmovilización y excluidos de otros. La tesis es un ejemplo de cómo las estrategias de identidad permiten la gobernabilidad en poblaciones globalizadas.
