Bordear la exposición, desconcertar el presente: Una aproximación a la práctica curatorial ante el devenir imperceptible del acontecimiento artístico

This article explores a series of questions relating to the practice of the exhibition as a defined medium and format, as well as to the acts of curatorial selection and mediation. They take into account the specific features of a series of artistic proposals that are not always recognizable as having an aesthetic configuration, and whose commitment to a minimal manifestation of the perceptible form, along with their eminently procedural logic and a generalised reticence to the conceptualisation of a discourse, result in a natural resistance to the event of the exhibition and the articulation of a narrative or a theoretical approach such as has traditionally been the basis of curatorial practice. Some of the most significant implications of this approach will be reviewed as a step towards the consideration of alternative forms of presentation. They are based on other cadences and time-scales, on other approaches to action or on the lack of it, with a view to enabling the experiencing of realities and relationships normally buried under the weight of the historical, the biographical or the concept, and under the prominence given to the curator’s voice in the construction of the exhibition experience.Este artículo explora problemáticas relativas a la exposición como medio y formato definido y a los actos de selección y mediación efectuados por el comisario/a, al hilo de las especificidades de una serie de propuestas artísticas no siempre discernibles como configuración estética. En ellas su compromiso con la mínima manifestación de la forma perceptible, su lógica eminentemente procesual y una generalizada reticencia a la conceptualización del discurso comportan un natural grado de resistencia al hecho expositivo y a la articulación de una narrativa o un enfoque teórico a los que la práctica curatorial ha tendido tradicionalmente a responder. Algunas de las implicaciones más relevantes de este tipo de gestos serán puestas en relación con la necesidad de pensar formas alternativas de presentación. Estas, sujetas a otros ritmos y temporalidades, a otros enfoques en torno a la acción o su ausencia, permiten experimentar vivencias y relaciones normalmente sepultadas por el peso de lo histórico, lo biográfico o el concepto, así como por el protagonismo que se otorga a la voz del comisario/a en la construcción de la experiencia expositiva

Magnetic resonance imaging reference values for cardiac morphology, function and tissue composition in adolescents.

BACKGROUND Cardiovascular magnetic resonance (CMR) is a precise tool for the assessment of cardiac anatomy, function, and tissue composition. However, studies providing CMR reference values in adolescence are scarce. We aim to provide sex-specific CMR reference values for biventricular and atrial dimensions and function and myocardial relaxation times in this population. METHODS Adolescents aged 15-18 years with no known cardiovascular disease underwent a non-contrast 3-T CMR scan between March 2021 and October 2021. The imaging protocol included a cine steady-state free-precession sequence for the analysis of chamber size and function, as well as T2-GraSE and native MOLLI T1-mapping for the characterization of myocardial tissue. FINDINGS CMR scans were performed in 123 adolescents (mean age 16 ± 0.5 years, 52% girls). Mean left and right ventricular end-diastolic indexed volumes were higher in boys than in girls (91.7 ± 11.6 vs 78.1 ± 8.3 ml/m2, p < 0.001; and 101.3 ± 14.1 vs 84.1 ± 10.5 ml/m2, p < 0.001), as was the indexed left ventricular mass (48.5 ± 9.6 vs 36.6 ± 6.0 g/m2, p < 0.001). Left ventricular ejection fraction showed no significant difference by sex (62.2 ± 4.1 vs 62.8 ± 4.2%, p = 0.412), whereas right ventricular ejection fraction trended slightly lower in boys (55.4 ± 4.7 vs. 56.8 ± 4.4%, p = 0.085). Indexed atrial size and function parameters did not differ significantly between sexes. Global myocardial native T1 relaxation time was lower in boys than in girls (1215 ± 23 vs 1252 ± 28 ms, p < 0.001), whereas global myocardial T2 relaxation time did not differ by sex (44.4 ± 2.0 vs 44.1 ± 2.4 ms, p = 0.384). Sex-stratified comprehensive percentile tables are provided for most relevant cardiac parameters. INTERPRETATION This cross-sectional study provides overall and sex-stratified CMR reference values for cardiac dimensions and function, and myocardial tissue properties, in adolescents. This information is useful for clinical practice and may help in the differential diagnosis of cardiac diseases, such as cardiomyopathies and myocarditis, in this population.

Estudos Artísticos

Nesta procura continuada de reunir escritos de artistas sobre outros criadores se reuniram neste número da Revista Croma dezasseis artigos que têm em comum a determinação interventiva e emancipada. Provoca-se o inconformismo, ensaia-se o pensamento. A intervenção advém do estatuto, do capital simbólico associado à autoria. O estatuto político da arte centra o artista e tona-o vocal. A sua perspetiva, a sua síntese, a sua fantasia, são agora meios para uma mediação junto de todos, em direção a uma transformação fundamental e construtora de um dos pontos essenciais da cultura: a arte emancipada. Com a emancipação da arte, criou-se uma nova referencialidade, um novo descentramento, um olhar exterior, um olhar do homem sobre o homem, um olhar político mediado pelas formas pensadas.info:eu-repo/semantics/publishedVersio
