L’article tracta sobre un projecte de restauració de la casa del Marxucal, construcció rural situada en el terme municipal d’Oliva. En ell es descriuen aspectes com la situació geogràfica i el context històric de la casa, s’hi fa un alçament planimètric de l’estat actual i una descripció detallada dels materials, de les tècniques constructives utilitzades i dels danys estructurals. A més, s’hi fa un recorregut per les diferents teories de la restauració d’alguns dels autors més destacats en aquest camp. També s’hi descriuen els criteris de projecte a seguir i s’hi fa una reconstrucció d’elements, una planimetria de projecte i de detalls constructius i una simulació d’alguns resultats de la intervenció. El projecte fou realitzat col·lectivament, durant el curs 2010-2011, per a l’assignatura de cinquè curs “Restauració Arquitectònica”, impartida per la professora Camila Mileto, del departament de Composició Arquitectònica de la Universitat Politècnica de Valènci

Las unidades del discurso oral. La propuesta Val.Es.Co. de segmentación de la conversación (coloquial)

El presente artículo resume y examina críticamente la propuesta de segmentación del discurso realizada en Briz y Grupo Val.Es.Co (2003). El modelo Val.Es.Co. consta de ocho unidades (discurso, diálogo, intercambio/ alternancia de turnos, intervención/turno, acto y subacto), tres órdenes (social, estructural e informativo) y cuatro posiciones (inicial, media, final e independiente); se caracteriza, además, por ser jerárquico y recursivo. La aplicación del modelo Val.Es.Co. permite la segmentación de una conversación coloquial sin residuos, así como un adecuado tratamiento de diversos fenómenos conversacionales (actos truncados, solapamientos, elementos suprasegmentales o marcadores discursivos)This paper summarizes and critically reviews the model of discourse segmentation made by Briz and Grupo Val.Es.Co (2003). This model is made up of eight units (discourse, dialogue, exchange/ turn taking, intervention/turn, act and subact), three orders (social, structural and informative) and four positions (initial, medial, final and independent). The Val.Es.Co model is also hyerarchical and recursive. By applying the Val.Es.Co model, a conversation can be divided into parts and subparts without any element remaining unanalyzed. Also, some specific features occurring in conversations such as false starts, overlappings, the segmentation value of prosodic features or discourse markers, can be successfully analyze

Cost-effectiveness analysis of pemetrexed versus docetaxel in the second-line treatment of non-small cell lung cancer in Spain: results for the non-squamous histology population

BackgroundThe objective of this study was to conduct a cost-effectiveness evaluation of pemetrexed compared to docetaxel in the treatment of advanced or metastatic non-small cell lung cancer (NSCLC) for patients with predominantly non-squamous histology in the Spanish healthcare setting.MethodsA Markov model was designed consisting of stable, responsive, progressive disease and death states. Patients could also experience adverse events as long as they received chemotherapy. Clinical inputs were based on an analysis of a phase III clinical trial that identified a statistically significant improvement in overall survival for non-squamous patients treated with pemetrexed compared with docetaxel. Costs were collected from the Spanish healthcare perspective.ResultsOutcomes of the model included total costs, total quality-adjusted life years (QALYs), total life years gained (LYG) and total progression-free survival (PFS). Mean survival was 1.03 years for the pemetrexed arm and 0.89 years in the docetaxel arm; QALYs were 0.52 compared to 0.42. Per-patient lifetime costs were € 34677 and € 32343, respectively. Incremental cost-effectiveness ratios were € 23967 per QALY gained and € 17225 per LYG.ConclusionsPemetrexed as a second-line treatment option for patients with a predominantly non-squamous histology in NSCLC is a cost-effective alternative to docetaxel according to the € 30000/QALY threshold commonly accepted in Spain

Assessment of a New ROS1 Immunohistochemistry Clone (SP384) for the Identification of ROS1 Rearrangements in Patients with Non–Small Cell Lung Carcinoma: the ROSING Study

Introduction: The ROS1 gene rearrangement has become an important biomarker in NSCLC. The College of American Pathologists/International Association for the Study of Lung Cancer/Association for Molecular Pathology testing guidelines support the use of ROS1 immunohistochemistry (IHC) as a screening test, followed by confirmation with fluorescence in situ hybridization (FISH) or a molecular test in all positive results. We have evaluated a novel anti-ROS1 IHC antibody (SP384) in a large multicenter series to obtain real-world data. Methods: A total of 43 ROS1 FISH-positive and 193 ROS1 FISH-negative NSCLC samples were studied. All specimens were screened by using two antibodies (clone D4D6 from Cell Signaling Technology and clone SP384 from Ventana Medical Systems), and the different interpretation criteria were compared with break-apart FISH (Vysis). FISH-positive samples were also analyzed with next-generation sequencing (Oncomine Dx Target Test Panel, Thermo Fisher Scientific). Results: An H-score of 150 or higher or the presence of at least 70% of tumor cells with an intensity of staining of 2+ or higher by the SP384 clone was the optimal cutoff value (both with 93% sensitivity and 100% specificity). The D4D6 clone showed similar results, with an H-score of at least 100 (91% sensitivity and 100% specificity). ROS1 expression in normal lung was more frequent with use of the SP384 clone (p < 0.0001). The ezrin gene (EZR)-ROS1 variant was associated with membranous staining and an isolated green signal FISH pattern (p = 0.001 and p = 0.017, respectively). Conclusions: The new SP384 ROS1 IHC clone showed excellent sensitivity without compromising specificity, so it is another excellent analytical option for the proposed testing algorithm

Comparison of thiol subproteome of the vent mussel Bathymodiolus azoricus from different Mid-Atlantic Ridge vent sites

Deep-sea hydrothermal mussels Bathymodiolus azoricus live in the mixing zone where hydrothermal fluid mixes with bottom seawater, creating large gradients in the environmental conditions and are one of the most studied hydrothermal species as a model of adaptation to extreme conditions. Thiol proteins, i.e. proteins containing a thiol or sulfhydryl group (SH) play major roles in intracellular stress defense against reactive oxygen species (ROS) and are especially susceptible to oxidation. However, they are not particularly abundant, representing a small percentage of proteins in the total proteome and therefore are difficult to study by proteomic approaches. Activated thiol sepharose (ATS) was used for the rapid and quantitative selection of proteins comprising thiol- or disulfide-containing subproteomes. This study aims to isolate thiol-containing proteins from the gills of B. azoricus collected in distinct hydrothermal vents and to study the thiol-containing subproteome as a function of site-specific susceptibility to ROS. Results show that ATS is a powerful tool to isolate the thiol-containing sub-proteome and differently-expressed protein spots showed significant differences among the three vent sites, supporting previous findings that specific environmental conditions are crucial for ROS formation and that B. azoricus have different susceptibilities to oxidative stress depending on the vent site they inhabit.5th PCRD Ventox project EVK3CT1999-00003info:eu-repo/semantics/publishedVersio

2-D difference gel electrophoresis approach to assess protein expression profiles in Bathymodiolus azoricus from Mid-Atlantic Ridge hydrothermal vents

Hydrothermal vent mussels Bathymodiolus azoricus are naturally exposed to toxic chemical species originated directly from vent chimneys. The amount of toxic elements varies significantly among vent sites along the Mid-Atlantic Ridge and B. azoricus must be able to adapt to changes in hydrothermal fluid composition, temperature and pressure. The aim of this work was to study changes in the proteome in the "gill-bacteria complex" of mussels B. azoricus from three hydrothermal vent sites with distinct environmental characteristics using 2-D Fluorescence Difference Gel Electrophoresis (2-D DIGE). Results showed that 31 proteins had different expression profiles among vent sites and both cluster and principal component analysis confirm a clear separation of mussels between sites. This suggests the existence of specific parameters grouping individuals from the same hydrothermal site. Protein spots of the more abundant differentially expressed proteins were excised, digested with trypsin and identified by mass spectrometry. All identified proteins (actin, ubiquinone, S-adenosylhomocysteine hydrolase, cysteine peptidases, chaperonin and catalase) have been related previously with oxidative stress conditions and are known to be affected by ROS inducing stressors, including metals. Results point out to specific adaptations at the proteome level of B. azoricus depending on the level of toxicants present in their environment.5th PCRD Ventox project (EVK3CT1999-00003)info:eu-repo/semantics/publishedVersio

Protein expression profiles in Bathymodiolus azoricus exposed to cadmium

Proteomic changes in the "gill-bacteria complex" of the hydrothermal vent mussel B. azoricus exposed to cadmium in pressurized chambers ((Incubateurs Pressurises pour l'Observation en Culture d'Animaux Marins Profonds - IPOCAMP) were analyzed and compared with the non-exposed control group. 2-D Fluorescence Difference Gel Electrophoresis (2D-DIGE) showed that less than 1.5% of the proteome of mussels and symbiotic bacteria were affected by a short-term (24 h) Cd exposure. Twelve proteins of the more abundant differentially expressed proteins of which six were up-regulated and six were down-regulated were excised, digested and identified by mass spectrometry. The identified proteins included structural proteins (actin/actin like proteins), metabolic proteins (calreticulin/calnexin, peptidyl-prolyl cis-trans isomerase, aminotransferase class-III, electron transfer flavoprotein, proteasome, alpha-subunit and carbonic anhydrase) and stress response proteins (chaperone protein htpG, selenium-binding protein and glutathione transferases). All differently expressed proteins are tightly connected to Cd exposure and are affected by oxidative stress. It was also demonstrated that B. azoricus was well adapted to Cd contamination therefore B. azoricus from hydrothermal vent areas may be considered a good bioindicator.EVK3CT1999-00003info:eu-repo/semantics/publishedVersio

Declaración de los nuevos diagnósticos de infección por el VIH en Cataluña: Implementación y resultados Reporting of newly diagnosed HIV infections in Catalonia. Barcelona. Spain: Implementation and results

Objetivos: Describir los resultados de la notificación de nuevos diagnósticos de infección por el virus de la inmunodeficiencia humana (NDIVIH) en Cataluña (2001-2003), y comparar las características de la epidemia como resultado de la utilización de este nuevo sistema de información junto con el Registro de casos de sida de Cataluña, con las halladas únicamente en el Registro de casos de sida. Métodos: Datos de las notificaciones de NDIVIH y de casos de sida entre 2001 y 2003 en Cataluña. Resultados: Entre los NDIVIH (n = 1.765), la vía de transmisión más frecuente fue las relaciones heterosexuales (46,8%), seguida de las relaciones homosexuales entre varones (26,7%) y el uso de drogas por vía parenteral (19,9%). Entre los 1.210 casos de sida, la forma de transmisión más frecuente fue el uso de drogas por vía parenteral (42,2%), seguida de relaciones heterosexuales (34,5%) y de las relaciones homosexuales entre varones (18,0%). La diferencia de utilizar una o 2 fuentes de información respecto a la variable vía de transmisión de la infección fue estadísticamente significativa. Conclusiones: El sistema de información basado en los datos sobre NDIVIH es viable, ha sido útil para conseguir los objetivos previstos en el sistema de vigilancia epidemiológica del VIH y proporciona información más precisa que el Registro de sida para describir los actuales patrones de transmisión del virus. La exhaustividad del nuevo sistema de información podría mejorar mediante la incorporación del diagnóstico de infección al sistema de enfermedades de declaración obligatoria.Objectives: To describe newly diagnosed HIV infections from the HIV Reporting System in Catalonia (2001-2003), and to compare the characteristics of the epidemic based on the use of the HIV Reporting System and the Catalonian AIDS Registry versus those based on the Catalonian AIDS Registry alone. Methods: Data were collected from newly diagnosed HIV infections and AIDS cases between 2001 and 2003 in Catalonia. Results: Among the newly diagnosed HIV infections (1,765) the most frequent route of HIV infection was heterosexual transmission (46.8%), followed by men who had sex with men (26.7%), and injecting drug use (19.9%). Out of the 1,210 AIDS cases, the most common route of HIV transmission was injecting drug used (42.2%), followed by (heterosexual transmission 34.5%) and MSM (18.0%). Comparison of routes of HIV transmission in the two reporting systems (HIV/AIDS versus AIDS) revealed statistically significant differences. Conclusions: The HIV/AIDS Reporting System based on reporting of newly diagnosed HIV infections is feasible, since it has been useful in achieving the objectives of epidemiological HIV infection surveillance. It also provides more accurate information than does the AIDS Registry, which can be used to describe recent patterns of HIV transmission. The completeness of the new reporting system may be enhanced by including the diagnosis of HIV infection among the diseases of mandatory notification

Estilos intelectuales de aprendizaje en la interacción educativa de profesores-as, estudiantes : hacia una enseñanza adaptativa

Identificar los estilos intelectuales y los estilos de enseñanza y aprendizaje de profesores y alumnos y examinar las relaciones entre ellos.. Muestra 1: 459 alumnos-as de ESO (40 por ciento) y primero de Bachillerato (60 por ciento) de tres institutos de Enseñanza Secundaria de Murcia y Cartagena. Muestra 2: 108 sujetos que imparten docencia a los alumnos anteriores.. Se realiza primero un estudio teórico sobre el origen, evolución y tratamiento del concepto de estilos intelectuales desde diferentes disciplinas. Se revisan conceptualmente los términos estilo de aprendizaje y enseñanza y se analizan los estilos intelectuales propuestos por Sternberg para referirse al autogobierno mental del alumno y del profesor. Después se realiza un estudio empírico para examinar la relación del estilo intelectual y de aprendizaje de los estudiantes con el estilo intelectual y de instrucción del profesor. Se adaptan los instrumentos, se aplican a la muestra de estudiantes y profesores y se recogen las calificaciones finales de los alumnos. Se realizan análisis correlacionales entre las variables de los distintos estilos intelectuales, análisis de varianza y pruebas t de diferencia de medias para examinar las diferencias entre los centros y se calcula el índice de similitud para la comparación de perfiles de profesores-alumnos en cada asignatura.. Test de Factor G de Catell de nivel 3, Inventario de Estilos Intelectuales para Alumnos de Sternberg, Cuestionario de Tareas Abiertas para la Medida del Estilo Intelectual de Sternberg, Inventario de Estilos Intelectuales de los Alumnos Evaluados por el Profesor de Sternberg, Knowledge Accessing Modes Inventory (KAMI) de Rancourt, Indicador de Tipo Myers-Briggs Forma G, NASSP, Learning Styles Inventory (LSI) de Canfield, Inventario de Estilos Intelectuales para Profesores de Sternberg, Inventario de Estilos Instruccionales (ISI) de Canfield.. Los resultados de la adaptación de los diferentes instrumentos son satisfactorios, mostrando unos índices de fiabilidad adecuados. Se evidencian bastantes relaciones significativas entre los diversos estilos intelectuales y de aprendizaje del alumno entre sí y con las calificaciones escolares. Se revelan diferencias entre los tres centros estudiados en el estilo intelectual de los alumnos, así como en varios estilos de aprendizaje, aunque no ocurre lo mismo cuando se tienen en cuenta los estilos intelectuales y de enseñanza del profesorado. La comparación de perfiles de profesores y alumnos pone de manifiesto que los profesores de las distintas asignaturas muestran estilos característicos predominantes y que, en algunos casos, la coincidencia entre el estilo intelectual del profesor y el del alumno está asociada a las calificaciones obtenidas por éste. Esto parece indicar que existe una mayor relación entre los estilos intelectuales de los alumnos y sus calificaciones cuando coinciden el estilo intelectual del alumno y el del profesor..Ministerio Educación CIDEBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín, 5 - 3 Planta; 28014 Madrid; Tel. +34917748000; Fax +34917748026; [email protected]
