Sobre la estratigrafía de los conglomerados de Campanué (Santa Liestra) y formaciones superiores del Eoceno (extremo occidental de la cuenca Tremp-Graus, Pirineo Central, Provincia de Huesca)

Se pone en evidencia la discordancia de los conglomerados de Campanué y su correlación sincrónica con los movimientos y discurtlancia intraluteciense de Mediano, Asimismo se establece el carácter discordante del Bartoniense inferior (calizas lacustres y lignitos de Capella y Laguarres). Finalmente se precisa la estratigrafía de los conglomerados de Canipanué y serie eocena superior

Precisiones sobre la "mise en place" del manto de Gavarnie en el borde norte del valle del Ebro (Región de Barbastro, provincia de Huesca)

La presencia de una ruptura sedimentaria materializada por una brecha poligénica entre la formación de Peraltilla y los yesos de Barbastro, unido al contexto general de los conocimientos regionales actuales, sitúan la "mise en place" del manto de Gavarnie (o fase Pirenaica mayor) como posteriora la deposición de los yesos y anterior a la formación de Peraltilla. En consecuencia los yesos de Barbastro no serían oligocenos sino de una edad comparable, al menos en parte, a las sales potásicas de Cataluña, es decir, Eoceno superior

Involvement of ethylene biosynthesis and signalling in fruit set and early fruit development in zucchini squash (Cucurbita pepo L.)

Background We have identified a kind of parthenocarpy in zucchini squash which is associated with an incomplete andromonoecy, i.e. a partial conversion of female into bisexual flowers. Given that andromonoecy in this and other cucurbit species is caused by a reduction of ethylene production in the female flower, the associated parthenocarpic development of the fruit suggested the involvement of ethylene in fruit set and early fruit development.Results We have compared the production of ethylene as well as the expression of 13 ethylene biosynthesis and signalling genes in pollinated and unpollinated ovaries/fruits of two cultivars, one of which is parthenocarpic (Cavili), while the other is non-parthenocarpic (Tosca). In the latter, unpollinated ovaries show an induction of ethylene biosynthesis and ethylene signal transduction pathway genes three days after anthesis, which is concomitant with the initiation of fruit abortion and senescence. Fruit set and early fruit development in pollinated flowers of both cultivars and unpollinated flowers of Cavili is coupled with low ethylene biosynthesis and signalling, which would also explain the partial andromonoecy in the parthenocarpic genotype. The reduction of ethylene production in the ovary cosegregates with parthenocarpy and partial andromonoecy in the selfing progeny of Cavili. Moreover, the induction of ethylene in anthesis (by ethephon treatments) reduced the percentage of bisexual parthenocarpic flowers in Cavili, while the inhibition of ethylene biosynthesis or response (by AVG and STS treatments) induces not only andromonoecy but also the parthenocarpic development of the fruit in both cultivars.Conclusions Results demonstrate that a reduction of ethylene production or signalling in the zucchini flower is able to induce fruit set and early fruit development, and therefore that ethylene is actively involved in fruit set and early fruit development. Auxin and TIBA treatments, inducing fruit set and early fruit development in this species, also inhibit ethylene production and the expression of ethylene biosynthesis and response genes. A model is presented that discusses the crosstalk between ethylene and auxin in the control of fruit set and early fruit development in zucchini squash.This work was supported by grants AGL2008-05619-C02-02/ALI and AGL2011-30568-C02-02/ALI, partly funded by ERDF (European Regional Development Fund) and by the Spanish Ministry of Science and Innovation, and grant CVI-02617, funded by ERDF and by the Consejería de Innovación, Ciencia y Empresa, Junta de Andalucía, Spain.

The much esteemed history of the ever-famous knight Don Quixote de la Mancha : el éxito editorial de una traducción abreviada inglesa

Análisis de una poco conocida versión abreviada del Quijote en inglés, publicada en Londres por N. y M. Boddington en 1699, y reeditada en varias ocasiones en los siglos XVIII y XIX. Se editan y analizan los paratextos literarios que acompañan la obra, así como las estampas que la ilustran. En el siglo XVII se publicaron cuatro traducciones abreviadas del Quijote, y, como se demuestra en este artículo, la versión de 1699 fue la que mejor acogida recibió. Se resalta aquí la importancia de esta obra para conocer mejor la primera recepción del Quijote en tierras inglesas.peer-reviewe

Los comportamientos de control en la pareja en la era digital: la aceptación de la violencia de género, el sexismo y los mitos del amor

Young people have incorporated information and communication technology (ICT) and its influence on socialization as a new instrument to exercise controlling behaviors in their relationships. The present research aims to analyse the influence of some variables that affect social perception of those controlling behaviors, such as the adopted role on the scene (i.e., protagonist vs. observer) and means of control that is used (i.e., face-to-face vs. WhatsApp) while considering the effect of attitudinal variables: acceptability of intimate partner violence against women (IPVAW), ambivalent sexism, and myths about romantic love. Two studies were implemented: Study 1 included women (n = 224) and Study 2 included men (n = 120), all of them college students. The main results revealed that both women and men perceive controlling behaviors amongst other peer couples; however, few of them recognize suffering or the exercise of these behaviors within their relationships. In addition, data pointed out the adopted role on the scene and the ideological variables (ambivalent sexism, acceptability of IPVAW, and myths about romantic love) that influenced social perception of dating violence; however, there was no influence of means of control. This research contributes to the previous literature, evidencing that controlling behaviors through technological means are accepted and normalized among young people. Additionally, it shows novel data about young people’s social perception of controlling behaviors in their relationships, depending on whether they adopt the role of observer or the role of protagonist in a violent situation.Con las tecnologías de la información y la comunicación (TIC) y su influencia en la socialización, los jóvenes han incorporado un instrumento más para ejercer comportamientos controladores en sus relaciones de pareja. Esta investigación pretende analizar la influencia de algunas variables que afectan a la percepción social de estos comportamientos controladores, como el rol del participante en el escenario (protagonista vs. observador u observadora) y el medio de control utilizado (cara a cara vs. WhatsApp), considerando el efecto de las variables ideológicas: aceptabilidad de la violencia, sexismo y mitos del amor romántico. Se llevaron a cabo dos estudios: un primer estudio con mujeres (n = 224) y uno segundo con hombres (n = 120), todos ellos estudiantes universitarios. Los principales resultados indicaron que tanto mujeres como hombres observan comportamientos controladores en otras parejas de su edad, aunque pocos reconocen sufrir o ejercer estos comportamientos en sus relaciones. Asimismo, se encuentra que el rol que se ocupa en el escenario y las variables ideológicas (sexismo ambivalente, aceptabilidad de la violencia y mitos sobre el amor romántico) influyen en la percepción social de la violencia en la pareja, si bien no se encontró influencia del medio de control. Estos hallazgos constituyen una aportación a la literatura existente, poniendo en evidencia que los comportamientos controladores ejercidos a través de los medios tecnológicos son aceptados y normalizados entre los jóvenes y las jóvenes. Asimismo, proporciona datos novedosos sobre la percepción social que esta población tiene de los comportamientos controladores en las relaciones en función de si se adopta el rol de observador o de protagonista de la situación violenta

Longitudinal association of dietary acid load with kidney function decline in an older adult population with metabolic syndrome

Background: Diets high in acid load may contribute to kidney function impairment. This study aimed to investigate the association between dietary acid load and 1-year changes in glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (UACR). Methods: Older adults with overweight/obesity and metabolic syndrome (mean age 65 ± 5 years, 48% women) from the PREDIMED-Plus study who had available data on eGFR (n = 5,874) or UACR (n = 3,639) at baseline and after 1 year of follow-up were included in this prospective analysis. Dietary acid load was estimated as potential renal acid load (PRAL) and net endogenous acid production (NEAP) at baseline from a food frequency questionnaire. Linear and logistic regression models were fitted to evaluate the associations between baseline tertiles of dietary acid load and kidney function outcomes. One year-changes in eGFR and UACR were set as the primary outcomes. We secondarily assessed ≥ 10% eGFR decline or ≥10% UACR increase. Results: After multiple adjustments, individuals in the highest tertile of PRAL or NEAP showed higher one-year changes in eGFR (PRAL, β: -0.64 ml/min/1.73 m2; 95% CI: -1.21 to -0.08 and NEAP, β: -0.56 ml/min/1.73 m2; 95% CI: -1.13 to 0.01) compared to those in the lowest category. No associations with changes in UACR were found. Participants with higher levels of PRAL and NEAP had significantly higher odds of developing ≥10% eGFR decline (PRAL, OR: 1.28; 95% CI: 1.07-1.54 and NEAP, OR: 1.24; 95% CI: 1.03-1.50) and ≥10 % UACR increase (PRAL, OR: 1.23; 95% CI: 1.04-1.46) compared to individuals with lower dietary acid load. Conclusions: Higher PRAL and NEAP were associated with worse kidney function after 1 year of follow-up as measured by eGFR and UACR markers in an older Spanish population with overweight/obesity and metabolic syndrome.
