Effect of Ripening and Growing Conditions on the Content in Ascorbic Acid in Paprika Landraces

[EN] Spain is one of the most important centres of diversity for Capsicum annuum peppers and the highest producer and exporter in Europe, and a plethora of ecotypes can be found throughout the country. Such genetic heritage offers the opportunity of selecting materials adapted to organic cultivation. In addition, ascorbic acid (AA) is a bioactive compound of paramount importance and therefore studies on the effect of organic cultivation on AA levels can provide an added value to those genotypes selected for organic cultivation. In this work C. annuum landraces were submitted to a comparative study (organic vs. conventional cultivation). Fruits from each accession and growing condition were sampled at both unripe and fully ripe stages and AA levels were estimated by potentiometric titration. Genotype (G), ripening stage (RS), growing conditions (GC), and G×GC and G×RS interactions contributed significantly to the observed variation. In addition, ripening increased AA in all accessions. Furthermore, the average AA content was higher in the organic plot at both unripe and fully ripe stages. In this way, most organic-produced accessions showed similar or higher values than those observed in the conventional plot. Finally, a significant genotype×growing conditions interaction was found for fully ripe stage, suggesting that there are ample opportunities for selecting vitamin C-rich paprika landraces adapted to organic cultivation.Ribes Moya, AM.; Fita Fernández, AM.; Raigón Jiménez, MD.; Rodríguez Burruezo, A.

Experiencias de Analíticas de Aprendizaje para el Seguimiento de Competencias Transversales

[EN] This article compiles a series of learning analytics experiences carried out in a multi-disciplinary university context in order to facilitate the monitoring students achieve-ment of certain soft skills. The experiences involve the use of computer tools for the collection, analysis and / or processing of data generated mainly from the students in-teractions with the Learning Management Systems used at the Universitat Polit`ecnica de Val`encia (PoliformaT, based on Sakai, Microsoft Teams, Videoapuntes). The results indicate that the integration of learning analytics techniques makes it possible to collect evidence and shed visibility in a partially automated way in order to support the process of monitoring the degree of achievement of certain soft skills.[ES] Este artículo recopila una serie de experiencias de analíticas de aprendizaje realizadas en un contexto universitario multi-disciplinar para poder facilitar el seguimiento del alcance de ciertas competencias transversales por parte del alumnado.

Drought tolerance among accessions of eggplant and related species

[EN] Adapting eggplant (Solanum melongena) cultivars to climate change requires the development of drought tolerant cultivars. In order to identify sources of variation for drought tolerance we have characterized nine accessions of eggplant and six of related species for tolerance to drought using a control with optimum irrigation and a drought treatment with a 50% reduction of irrigation. Many differences were found in the materials studied for the four parameters measured (leaf length and width, plant height and dry biomass). The materials with better performance have been S. elaeagnifolium and one accession of eggplant, while the most discriminant traits have been plant height and dry biomass. Overall, the results indicate that there is a large diversity in the germplasm of eggplant and related species for tolerance to drought.This work was completed as part of the initiative “Adapting Agriculture to Climate Change: Collecting, Protecting and Preparing Crop Wild Relatives”, which is supported by the Government of Norway. The project is managed by the Global Crop Diversity Trust with the Millennium Seed Bank of the Royal Botanic Gardens, Kew and is implemented in partnership with national and international gene banks and plant breeding institutes.Fita Fernández, AM.; Fioruci, F.; Plazas Ávila, MDLO.; Rodríguez Burruezo, A.; Prohens Tomás, J.

Mejora del aroma y flavor en variedades tradicionales de pimiento y especies relacionadas (capsicum sp.): diversidad intra e interespecífica

Pimientos, chiles y ajíes son términos para denominar especies del género Capsicum, destacando el pimiento común (Capsicum annuum) por su amplia distribución, diversidad varietal, importancia económica y ser la predominante en España (Nuez et al., 2003). Es una de las hortícolas más importantes y se emplea en innumerables recetas, contribuyendo con su particular pungencia y/o flavor (DeWitt y Bosland, 2009). Si bien el conocimiento sobre factores relativos a la pungencia es muy amplio, los estudios sobre volátiles responsables del flavor son muy escasos y nulos en materiales tradicionales. Así, los primeros estudios sobre diversidad en volátiles de Capsicum, realizados por el Grupo de Mejora del pimiento del COMAV, permitieron identificar más de 300 compuestos (Rodríguez-Berruezo et al., 2010; Kolmannsberger et al., 2011). Se presentan avances sobre estudios de diversidad y premejora de la fracción volátil en variedades tradicionales de pimiento y se discuten las diferencias con sus formas modernas

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Análisis de componentes principales

El análisis de componentes principales pretende transformar el conjunto de datos inicial (de variables correlacionadas) en un nuevo conjunto reducido de nuevas variables independientes, llamadas componentes principales. El análisis de componentes principales es un análisis estadístico que pertenece a los denominados métodos multivariantes. Se utiliza en multitud de disciplinas para interpretar los datos. En este video se realiza un ejemplo para la interpretación de datos de caracterización morfológica típicos de la conservación de recursos fitogenéticos.https://media.upv.es/player/?id=3c6bfd35-88f2-4419-8f17-85e538cf6189Fita Fernández, AM.
