Documentales sobre el 15-m: una modalidad plural para una revolución plural

The biased media coverage on 15-M in 2011 grants the documentaries produced on this topic the ability to intervene in the social imaginary; at the same time, it reveals the difficulty of representing this social movement. In this article I will study the documentaries #Indignados. Del 15M al 20N, 15M: “Excelente, Revulsivo, Importante”, #Acampadasol: historia de una ciudad, Falsos horizontes and Libre te quiero in order to show how the diversity of documentary modes —using Bill Nichol’s conceptual scheme— used by the authors reflects that 15-M cannot be easily confined within the conventions of a unique type of representation.La deficiente cobertura informativa que los medios llevaron a cabo sobre el 15-M en 2011, además de otorgar a los documentales producidos sobre el tema la capacidad de intervenir en el imaginario social, desveló la dificultad de representar esta movilización. En este artículo se analizan los documentales #Indignados. Del 15M al 20N, 15M: “Excelente, Revulsivo, Importante”, #Acampadasol: historia de una ciudad, Falsos horizontes y Libre te quiero para mostrar cómo la variedad de modos documentales —usando el esquema conceptual de Bill Nichols— usados por los cineastas revela que el 15-M es un fenómeno difícilmente encasillable dentro de un único tipo de representación

Herramientas de aprendizaje para estudiantes de secundaria en el campo de la Genética

Se ha diseñado una actividad: la caracterización molecular de la mutación de un gen que modifica el color de los ojos en Drosophila melanogaster, partiendo de un carácter morfológico, el color de los ojos, se obtendrá la secuencia del gen responsable y su localización en el genoma de la especie. Se pretende desarrollar una actividad práctica que permita a los alumnos de segundo ciclo de la ESO comprender la genética y la genómica y cómo estos conocimientos se pueden aplicar a distintas áreas: salud, biotecnología o impacto ambiental

Two-center experience comparing the use of the FLOT4 and CROSS schemes for patients with gastric, esophageal, and gastroesophageal junction adenocarcinoma

Introduction. Gastric (GAD), gastroesophageal junction (GEJA), and esophageal adenocarcinoma (EAD) share pathophysiological features. At localized stages, FLOT is used perioperatively for the treatment of GAD and GEJA and CROSS for EAD and some GEJA. Although both therapies have been compared with MAGIC, comparative randomized data on FLOT and CROSS are not yet available. Material andmethods. We retrospectively analyzed and compared 40 patients treated with FLOT and 16 patients treated with CROSS in terms of clinical features and neoadjuvant, surgical, adjuvant, and survival outcomes. Results. At the time of analysis, 65% of patients treated with FLOT4 and 56.3% with CROSS remained in complete remission. Those who progressed after FLOT4 did so mainly at the peritoneal level (25%) and after CROSS at the bone, lymph node, and peritoneal levels (12.5% respectively). Six patients (37.5%) died after CROSS (median OS of 17.5 months; 95% CI 2–41) and 10 (25%) after FLOT4 (median OS 16.5 months; 95% CI 11–22). For the living patients, the median numbers of months from diagnosis to the follow-up cutoff date were 47.5 (95% CI 11–67) and 27 (95% CI 14–44) for CROSS and FLOT4, respectively. There were no significant differences in median OS estimated by Kaplan Meier analysis [FLOT4: 50 ± 4.6 months (95% CI 40.9–59.2); CROSS: 51.2 ± 7 months (95% CI 37.4–65.0; p = 0.79)].  Conclusions. Although we obtained lower pCR rates; TNM downstaging after neoadjuvant therapy, R0 rates, tolerance, PFS, and OS were similar in both groups and comparable with trial results. The adjuvant compliance rate was high with FLOT4. CROSS allows sequencing with nivolumab in PD-L1+ tumors

Laboratorio en abierto: aprendendiendo a copiar ADN.2

El objetivo principal del proyecto es la puesta a punto de recursos educativos en abierto (REA) dirigidos a los alumnos de secundaria. La propuesta pretende desarrollar habilidades, para la resolución de problemas científicos, a través de retos que despierten el interés y la imaginación de los alumnos de secundaria. En esta propuesta la resolución de los problemas planteados estaría basada en la aplicación de una herramienta que ha revolucionado la genética y biología, la reacción en Cadena de la Polimerasa, conocida como PCR

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019

Altres ajuts: Spanish AIDS Research Network; European Funding for Regional Development (FEDER).Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M&gt;70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0&lt;e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level
