The performance of the future? An interpretation about performative practices

En este documento se hace referencia a la evolución de la performance desde sus inicios hasta la actualidad, relacionando esta práctica con obras que presentan rasgos de performatividad pero que no dejan de lado la dimensión objetual. Asimismo, se plantean nuevos escenarios donde poder especular acerca de la supuesta autonomía de este medio y las posibilidades estético‐políticas que ofrece. La intención principal de este texto es forjar una visión crítica y una lectura más o menos personal acerca de lo que hoy llamamos “performance”.In this paper, reference is made to the evolution of performance from its beginnings to the present, in order to make links with other works that feature performativity and objectuality at the same time. Likewise, new scenarios where we can speculate about the supposed autonomy of this medium and the aesthetic‐political possibilities it offers, are proposed. The main objective of this text is to give rise to critical thinking and a more or less personal reading about what we now call 'performance'

Precarious practices within the institution: A journey through the restoration of the agency

En este artículo de investigación podrán encontrarse vivencias que dan sentido al discurso artístico y que no pueden separarse de lo meramente laboral. Así, se expondrán varios proyectos artísticos que surgen de la precariedad y que podrían desbordar las estructuras de poder que se dan dentro de la institución a través de mecanismos apropiacionistas y a la creación de comunidades. Se plantea un recorrido por diversas instituciones culturales no sólo con la finalidad de mostrar escenarios comunes y cotidianos sino también para ejemplificar desde la experiencia personal las distintas posiciones que puede tomar el cuerpo frente a la violencia institucional.In this paper you can find personal experiences related to the work that give form to the discourse of the artist. Thus, several artistic projects that arise from precariousness and that could endanger the power structures of the institution through appropriation mechanisms and the creation of communities will be exposed. A journey through various cultural institutions is proposed, not only to show common and everyday scenarios, but also to exemplify the different positions that the body can take against institutional violence

Antihypertensive Effects of Virgin Olive Oil (Unfiltered) Low Molecular Weight Peptides with ACE Inhibitory Activity in Spontaneously Hypertensive Rats

The low molecular weight peptide composition of virgin olive oil (VOO) is mostly unknown. We hypothesised that unfiltered VOO could possess low molecular weight peptides with antihypertensive activity. We produced unfiltered VOO and obtained a water-soluble peptide extract from it. The peptides were separated by size-exclusion using fast protein liquid chromatography, and the low molecular weight fraction was analysed by nanoscale liquid chromatography-Orbitrap coupled with tandem mass spectrometry and de novo sequencing. We selected 23 peptide sequences containing between 6 and 9 amino acids and molecular masses ranging 698–1017 Da. Those peptides were chemically synthesised and their angiotensin-converting enzyme (ACE) inhibitory activity was studied in vitro. Seven peptides showed a strong activity, with half maximal inhibitory concentration (IC50) <10 um. The antihypertensive effects of the four most active synthesised ACE inhibitor peptides were studied in spontaneously hypertensive rats (SHR). Acute oral administration of synthetic peptides RDGGYCC and CCGNAVPQ showed antihypertensive activity in SHR. We conclude that unfiltered VOO naturally contains low molecular weight peptides with specific ACE inhibitory activity and antihypertensive effects in SHR.This research was funded by the European Regional Development Funds under the agreement signed between MINECO and CSIC for the realization of the RECUPERA 2020 project

Mechanical characterization of Portland cement mortars containing petroleum or coal tar

En este artículo se presentan datos experimentales de resistencia a flexión y a compresión de morteros de cemento Portland con adición y sustitución de breas de petróleo y de alquitrán de carbón, que son subproductos de la industria del carbón o del petróleo. Los materiales estudiados son breas de alquitrán de carbón A (BACA) y B (BACB), y dos breas de petróleo (BPP) y (BPT). Los datos demuestran la viabilidad del uso de estas breas en la fabricación de morteros con menores contenidos de cemento, permitiendo diseñar un nuevo material sostenible con el medio ambiente y que contribuya a reducir el impacto ambiental de los materiales de construcción, hecho que permite abrir una nueva vía de valorización de estos subproductos.This article discusses experimental data on the flexural and compressive strength of Portland cement mortars containing additions or cement replacements consisting in petroleum or coal tar, by-products of the oil and coal industries. The materials studied were two coal (BACA and BACB) and two petroleum (BPP and BPT) tars. The results show that it is feasible to use such materials as a partial replacement for cement in mortar manufacture. This should lead to the design of a new sustainable product that will contribute to lowering the environmental impact of construction materials while at the same time opening up an avenue for the re-use of this type of industrial by-products.Generalitat Valenciana (Ref.

The Poly I:C maternal immune stimulation model shows unique patterns of brain metabolism, morphometry, and plasticity in female rats

Introduction: Prenatal infections are associated with an increased risk of the onset of schizophrenia. Rodent models of maternal immune stimulation (MIS) have been extensively used in preclinical studies. However, many of these studies only include males, omitting pathophysiological features unique to females. The aim of this study is to characterize the MIS model in female rats using positron emission tomography (PET), structural magnetic resonance imaging (MR), and neuroplasticiy studies. Methods: In gestational day 15, Poly I:C (or Saline) was injected into pregnant Wistar rats to induce the MIS model. Imaging studies: [18F]-fluoro-2-deoxy-D-glucose-PET scans of female-offspring were acquired at post-natal day (PND) 35 and PND100. Furthermore, T2-MR brain images were acquired in adulthood. Differences in FDG uptake and morphometry between groups were assessed with SPM12 and Regions of Interest (ROI) analyses. Ex vivo study: The density of parvalbumin expressing interneurons (PV), perineuronal nets (PNN), and parvalbumin expressing interneurons surrounded by perineuronal nets (PV-PNN) were evaluated in the prelimbic cortex and basolateral amygdala using confocal microscopy. ROIs and neuroplasticity data were analyzed by 2-sample T-test and 2-way-ANOVA analyses, respectively. Results: A significant increase in brain metabolism was found in all animals at adulthood compared to adolescence. MIS hardly modified brain glucose metabolism in females, highlighting a significant hypometabolism in the thalamus at adulthood. In addition, MIS induced gray matter (GM) enlargements in the pituitary, hippocampus, substantia nigra, and cingulate cortex, and GM shrinkages in some thalamic nuclei, cerebelar areas, and brainstem. Moreover, MIS induced white matter shrinkages in the cerebellum, brainstem and corpus callosum, along with cerebrospinal fluid enlargements in the lateral and 4th ventricles. Finally, MIS reduced the density of PV, PNN, and PV-PNN in the basolateral amygdala. Conclusion: Our work showed in vivo the differential pattern of functional and morphometric affectation in the MIS model in females, as well as the deficits caused at the synaptic level according to sex. The differences obtained highlight the relevance of including both sexes in psychiatric research in order to consider their pathophysiological particularities and successfully extend the benefits obtained to the entire patient population.MS-M was supported by the Ministerio de Ciencia e Innovación, Instituto de Salud Carlos III (PI17/01766, BA21/0030); co-financed by European Regional Development Fund (ERDF), “A way to make Europe”; project PID2021_128862OB-I00 funded by MCIN/AEI/10.13039/501100011033/FEDER, UE; Centro de Investigación Biomédica en Red de Salud Mental (CIBERSAM; project number CB07/09/0031); Delegación del Gobierno para el Plan Nacional sobre Drogas (project number 2017/085); and Fundación Alicia Koplowitz.

Evolution and implementation of CDIO initiatives at ETSII-UPM

The School of Industrial Engineering at Universidad Politécnica de Madrid (ETSII-UPM) has been promoting student-centred teaching-learning activities, according to the aims of the Bologna Declaration, well before the official establishment of the European Area of Higher Education. Such student-centred teaching-learning experiences led us to the conviction that project based learning is rewarding, both for students and academics, and should be additionally promoted in our new engineering programmes, adapted to the Grade-Master structure. The level of commitment of our teachers with these activities is noteworthy, as the teaching innovation experiences carried out in the last ten years have led to the foundation of 17 Teaching Innovation Groups at ETSII-UPM, hence leading the ranking of teaching innovation among all UPM centres. Among interesting CDIO activities our students have taken part in especially complex projects, including the Formula Student, linked to the complete development of a competition car, and the Cybertech competition, aimed at the design, construction and operation of robots for different purposes. Additional project-based learning teamwork activities have been linked to toy design, to the development of medical devices, to the implementation of virtual laboratories, to the design of complete industrial installations and factories, among other activities detailed in present study. The implementation of Bologna process will culminate at ETSII-UPM with the beginning of the Master’s Degree in Industrial Engineering, in academic year 2014-15. The program has been successfully approved by the Spanish Agency for Accreditation (ANECA), with the inclusion of a set of subjects based upon the CDIO methodology denominated generally “INGENIA”, linked to the Spanish “ingeniar” (to provide ingenious solutions), also related etymologically in Spanish with “ingeniero”, engineer. INGENIA students will live through the complete development process of a complex product or system and there will be different kind of projects covering most of the engineering majors at ETSII-UPM

European Registry on Helicobacter pylori Management: Effectiveness of First and Second-Line Treatment in Spain

The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump inhibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10,267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effectiveness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. "Optimized" H. pylori therapies achieve over 90% success in Spain

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study

Background In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new “Trigger Tool” represents a sensitive predictor of adverse events in general surgery. Methods An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described “Trigger Tool” based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis. Results The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The “Trigger Tool” had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the “Trigger Tool”. Conclusions The “Trigger Tool” has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies

Programa nacional de mejora y conservación de los recursos genéticos de la encina y el alcornoque frente a la seca

Como respuesta a la gravedad de los procesos de decaimiento y mortalidad de la encina y el alcornoque, que amenazan la sostenibilidad de sus masas en la Península Ibérica, en el año 2019 se constituyó el subgrupo de trabajo “Mejora genética y fisiológica”, que forma parte del grupo de trabajo “Seca”, coordinado por el MITECO. Este subgrupo incluye a científicos y técnicos de varias administraciones y numerosos centros de investigación y Universidades y una empresa pública, expertos en mejora genética, fitopatología, ecología, propagación vegetativa, bioquímica y biología molecular. El programa tiene como objetivo la selección de genotipos de Quercus ilex y Q. suber tolerantes al estrés hídrico y a la podredumbre radical provocada por Phytophthora cinnamomi. A partir del estudio de 18 poblaciones y de 194 árboles “escape” seleccionados en focos de seca, se espera seleccionar un material apto para restaurar zonas afectadas por problemas de decaimiento. Se presenta una síntesis de las primeras actividades de caracterización e identificación de árboles escape en focos de seca, ensayos de invernadero para el estudio de la variabilidad poblacional en cuanto a vigor y tolerancia al estrés, recogida de muestras vegetales y edáficas para el análisis genético, molecular y de microbioma, identificación de marcadores moleculares asociados a resiliencia y micropropagación del material de mayor valor potencial
