"La bestia y el Soberano", un intento de censura que pone en entredicho los intereses de la organización del Museo de Arte Contemporáneo de Barcelona.

Facultat de Belles Arts, Universitat de Barcelona. Assignatura: Sociología de l'Art, Curs: 2014-2015El artículo pretende realizar un análisis a las estructuras y dinámicas del arte contemporáneo, tomando como objeto de estudio el Museo de Arte Contemporáneo de Barcelona, a raíz de la noticia de intento de censura de una de sus obras. Desarrollado dentro del marco de la sociología del arte, se estudian el campo, los agentes y los tipos de capital que propone Bourdieu, dando como resultado un artículo de crítica que pone en duda los intereses de la organización

Copias Fotográficas a la Albúmina: Estudio de la técnica y metodología en su conservación

Treballs Finals de Grau de Conservació-Restauració de Béns Culturals. Facultat de Belles Arts. Universitat de Barcelona, Curs: 2017-2018, Tutor: Ramells Cabrelles, Carme[spa] El presente trabajo, como herramienta introductoria en el conocimiento de la técnica fotográfica de positivado a la albúmina; aborda aspectos históricos, matéricos, procesos y procedimientos de elaboración, mecanismos de degradación de la imagen y las posibles vías de su conservación. Mediante el análisis teórico, experimentación y estudio de casos; se vertebra un documento básico para la comprensión y preservación de este Bien Cultural. Las impresiones a la albúmina son el producto de la técnica fotográfica que positiva la imagen por contacto directo del negativo con papel, preparado con una solución salina y clara de huevo antes de ser sensibilizado. Su uso extendido en la segunda mitad del siglo XIX hace de éste patrimonio una entidad susceptible de localizarse prácticamente en cualquier institución gestora de Bienes Culturales, haciendo imprescindible su estudio y significación.[eng] The current paper, as an introductory resource on the knowledge of the albumen printing process, addresses historical aspects, characterization, processing and printing procedures, image deterioration patterns and possible ways of conservation. Through theoretical analysis, experimentation and case studies; a basic document for the understanding and preservation of this Cultural Heritage is structured. The albumen print material consists of a paper support coated with egg white mixed with a saline solution, and then sensitized before exposed in contact with a negative in sunlight. Because of the dominance of the albumen print material in photographic practice in the second half of nineteenth century, albumen prints can be founded nowadays in practically any Cultural Heritage institution, which makes its study and signification essential

Can the Cytokine Profile According to ABO Blood Groups Be Related to Worse Outcome in COVID-19 Patients? Yes, They Can

Producción CientíficaSevere status of coronavirus disease 2019 (COVID-19) is extremely associated to cytokine release. Moreover, it has been suggested that blood group is also associated with the prevalence and severity of this disease. However, the relationship between the cytokine profile and blood group remains unclear in COVID-19 patients. In this sense, we prospectively recruited 108 COVID-19 patients between March and April 2020 and divided according to ABO blood group. For the analysis of 45 cytokines, plasma samples were collected in the time of admission to hospital ward or intensive care unit and at the sixth day after hospital admission. The results show that there was a risk of more than two times lower of mechanical ventilation or death in patients with blood group O (log rank: p = 0.042). At first time, all statistically significant cytokine levels, except from hepatocyte growth factor, were higher in O blood group patients meanwhile the second time showed a significant drop, between 20% and 40%. In contrast, A/B/AB group presented a maintenance of cytokine levels during time. Hepatocyte growth factor showed a significant association with intubation or mortality risk in non-O blood group patients (OR: 4.229, 95% CI (2.064–8.665), p < 0.001) and also was the only one bad prognosis biomarker in O blood group patients (OR: 8.852, 95% CI (1.540–50.878), p = 0.015). Therefore, higher cytokine levels in O blood group are associated with a better outcome than A/B/AB group in COVID-19 patients.Instituto de Salud Carlos III (grant COV20/00491)Junta de Castilla y León (grant 18IGOF

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
