New variable stars discovered in the fields of three Galactic open clusters using the VVV Survey

This project is a massive near-infrared (NIR) search for variable stars in highly reddened and obscured open cluster (OC) fields projected on regions of the Galactic bulge and disk. The search is performed using photometric NIR data in the $J$-, $H$- and $K_s$- bands obtained from the Vista Variables in the V\'ia L\'actea (VVV) Survey. We performed in each cluster field a variability search using Stetson's variability statistics to select the variable candidates. Later, those candidates were subjected to a frequency analysis using the Generalized Lomb-Scargle and the Phase Dispersion Minimization algorithms. The number of independent observations range between 63 and 73. The newly discovered variables in this study, 157 in total in three different known OCs, are classified based on their light curve shapes, periods, amplitudes and their location in the corresponding color-magnitude $(J-K_s,K_s)$ and color-color $(H-K_s,J-H)$ diagrams. We found 5 possible Cepheid stars which, based on the period-luminosity relation, are very likely type II Cepheids located behind the bulge. Among the newly discovered variables, there are eclipsing binaries, $\delta$ Scuti, as well as background RR Lyrae stars. Using the new version of the Wilson & Devinney code as well as the "Physics Of Eclipsing Binaries" (PHOEBE) code, we analyzed some of the best eclipsing binaries we discovered. Our results show that these studied systems turn out to be ranging from detached to double-contact binaries, with low eccentricities and high inclinations of approximately $80^{\circ}$. Their surface temperatures range between $3500$K and $8000$K.Comment: 34 pages, 10 figures, 7 tables. Accepted for publication in New Astronom

Effect of the fungicide Prochloraz-Mn on the cell wall structure of Verticillium fungicola

The chemical structure of the cell wall of two isolates of Verticillium fungicola collected from diseased fruit bodies of the commercial mushroom Agaricus bisporus treated with the fungicide Prochloraz-Mn was analyzed. The isolates were obtained during different periods of time and grown in the absence and presence of the LD50 values of the fungicide for V. fungicola. In addition, another V. fungicola isolate collected previous to the routine utilization of Prochloraz-Mn but grown under the same conditions was also analyzed. The overall chemical composition of the cell wall from the three isolates showed detectable differences in their basic components, with a significant decrease in the protein content in fungicide-treated cells. This inhibitory effect was partially compensated by an increase in neutral and/or aminated carbohydrates and was accompanied by appreciable modifications of polysaccharide structure, as deduced after methylation analysis and gas-liquid chromatography- mass spectrometry (GLC-MS). Moreover, differences in hyphal morphology caused by the fungicide were observed by transmission electron microscopy (TEM)

Varón joven con insuficiencia cardíaca derecha e hipertensión pulmonar

A 33-years old man with previous non-controlled hyperthyroidism was admitted to the hospital because of right-sided heart failure. In a transthoracic echocardiography (TTE) a moderate pulmonary hypertension (PH) and dilatation of the right chambers were detected. We ruled out left-sided heart failure, lung, thromboembolic, autoimmune or infectious diseases and portal hypertension. The patient received beta blockers, digoxin and carbimazole at high doses. Concurring with the normalization of the thyroid function the following TTEs showed reduction of the pulmonary artery pressure and right chambers diameter. Identifying hyperthyroidism as a cause of PH has important implications in its management and prognosis.Varón de 33 años con hipertiroidismo no controlado que ingresó por insuficiencia cardíaca descompensada de predominio derecho objetivándose en ecocardiografía transtorácica (ETT) hipertensión pulmonar (HTP) moderada y dilatación de cavidades derechas. Descartados el fallo cardíaco izquierdo, enfermedad pulmonar y enfermedad tromboembólica crónica, enfermedades autoinmunes o infecciosas o hipertensión portal, recibió tratamiento con betabloqueantes, digoxina y carbimazol a altas dosis. Paralelo a la normalización de la función tiroidea se objetivó en ETT seriadas disminución de la presión de la arteria pulmonar y tamaño de las cavidades derechas. Identificar al hipertiroidismo como causa de HTP es importante por las implicaciones terapéuticas y el buen pronóstico en comparación con otras causas de la misma

Role of telemedicine in the management of oral anticoagulation in atrial fibrillation: a practical clinical approach

COVID-19; Direct oral anticoagulant; TelemedicineCOVID-19; Anticoagulante oral directo; TelemedicinaCOVID-19; Anticoagulant oral directe; TelemedicinaCompared with face-to-face consultations, telemedicine has many advantages, including more efficient use of healthcare resources, partial relief of the burden of care, reduced exposure to COVID-19, treatment adjustment, organization of more efficient healthcare circuits and patient empowerment. Ensuring optimal anticoagulation in atrial fibrillation patients is mandatory if we want to reduce the thromboembolic risk. Of note, telemedicine is an excellent option for the long-term management of atrial fibrillation patients. Moreover, direct oral anticoagulants may provide an added value in telemedicine (versus vitamin K antagonists), as it is not necessary to monitor anticoagulant effect or make continuous dosage adjustments. In this multidisciplinary consensus document, the role of telemedicine in anticoagulation of this population is discussed and practical recommendations are provided.V Barrios has received consultancy/lecture fees from Bayer, BMS/Pfizer, Boehringer Ingelheim and Daiichi Sankyo.

Influence of solvent on poly(2-(dimethylamino)ethyl methacrylate) dynamics in polymer-concentrated mixtures: a combined neutron scattering, dielectric spectroscopy and calorimetric study

We have investigated the dynamical processes-α-relaxation, local motions of the side-groups, and methyl group rotations-in poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) in the dry state and in mixtures (at 70 wt% polymer concentration) with tetrahydrofuran (THF) and water, to address the question as to how these polymer motions are affected by plasticizers interacting in different ways with the polymer. Differential scanning calorimetry, dielectric spectroscopy, and neutron scattering techniques on labeled samples (with deuterated solvents to isolate the signal of the polymer component) have been combined. The α-relaxation is drastically affected, with similar shifts of the glass-transition temperature for both solvents. Effects of compositional heterogeneities and reduction of the fragility are also observed. On the contrary, methyl-group dynamics are unaffected by the presence of solvent. Regarding side-group local motions (β-relaxation), two kinds of components-a slow and a fast one-could be identified in the dry state. On the basis of the spatial information provided by neutron scattering, a model for the geometry of the motions involved in the fast component has been proposed. Adding solvent, this process would remain essentially unaltered, but the population involved in the slower one would be reduced. With THF as solvent, this reduction would be complete, but with water it would be only partial. This could be attributed to rather heterogeneous distribution of water molecules in the polymer likely associated with the presence of water clusters. Such a scenario would also explain the much more pronounced broadening of the glass-transition region observed for the polymer in the aqueous mixture with respect to that induced by THF.Financial support from the Projects MAT2012-31088 (Spanish MINECO and EU) and IT-654-13 (Basque Government) is acknowledged.

This is a case report corresponding to a young woman with neurological symptoms (headache and diplopia), a structural lesion of the orbit and lesions on chest radiography, where a broad differential diagnosis arises and where the challenge is to quickly locate the most accessible primary lesion that allows more thorough characterization clinical case and enables more accurate treatment.Se trata de un caso clínico correspondiente a una mujer joven con clínica neurológica (cefalea y diplopia), una lesión estructural de la órbita, junto con una radiografía de tórax patológica, donde se plantea un amplio diagnóstico diferencial y donde el reto consiste en la rápida localización de la lesión primaria más accesible que permita la tipificación más exhaustiva y posibilite el tratamiento más certero

Factores psicosociales de riesgo y burnout en policías: un análisis de redes

Work stress has been identified as a critical factor affecting mental health in police officers. Psychosocial factors increase the impact of work stress on police officers and,in the long run,contribute to the onset of burnout symptoms. In this research asample of 323 was studied to study the relationship between psychosocial risk factors and the probability of suffering burnout symptoms. The participant’s answers to the MBI-GSandF-PSICO(version4.0) were analysed by using network analysis.There sults show that psychosocial risk factors are strongly associated in network models when higher level of cynicism and emotional exhaustion are observed. Additionally, higher levels of burnout in police officers were observed when lower autonomy,higher psychological demands, role ambiguities and alower perceived social support were present. Results are discussed considering its theoretical and applied relevance to design healthier work environments an defficient psychologicalinterventionsEl estrés laboral crónico ha sido identificado como uno de los riesgos laborales más importantes que afecta a la salud mental de los agentes de policía. Existen ciertos factores psicosociales que incrementan el estrés laboral en la policía y que, a largo plazo, desencadenan síntomas compatibles con el burnout. En este trabajo se ha utilizado una muestra integrada por 323 policías para valorar la relación que se establece entre los factores psicosociales de riesgo y la probabilidad de experimentar síntomas compatibles con el burnout. Las respuestas de los participantes al MBI-GS y al F-PSICO (versión 4.0) fueron examinadas utilizando análisis de redes. Los resultados muestran que existen redes de factores psicosociales de riesgo más cohesionadas cuando los niveles de cinismo y agotamiento emocional son más elevados. Además, se observa mayor nivel de burnout asociados con una baja autonomía, altas demandas psicológicas, conflictos en el desempeño de rol y un bajo apoyo social percibido. Los resultados son discutidos en términos de su implicación teórica y de su utilidad práctica frente al diseño de entornos de trabajo más saludables, así como frente a la intervención psicológica

New VVV Survey Globular Cluster Candidates in the Milky Way Bulge

© 2017 The American Astronomical Society. All rights reserved.It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major problems for finding globular clusters located toward the bulge. We use the deep near-IR photometry of the VISTA Variables in the Vía Láctea (VVV) Survey to search for globular clusters projected toward the Galactic bulge, and hereby report the discovery of 22 new candidate globular clusters. These objects, detected as high density regions in our maps of bulge red giants, are confirmed as globular cluster candidates by their color-magnitude diagrams. We provide their coordinates as well as their near-IR color-magnitude diagrams, from which some basic parameters are derived, such as reddenings and heliocentric distances. The color-magnitude diagrams reveal well defined red giant branches in all cases, often including a prominent red clump. The new globular cluster candidates exhibit a variety of extinctions (0.06 < A Ks < 2.77) and distances (5.3 < D < 9.5 kpc). We also classify the globular cluster candidates into 10 metal-poor and 12 metal-rich clusters, based on the comparison of their color-magnitude diagrams with those of known globular clusters also observed by the VVV Survey. Finally, we argue that the census for Galactic globular clusters still remains incomplete, and that many more candidate globular clusters (particularly the low luminosity ones) await to be found and studied in detail in the central regions of the Milky Way.Peer reviewedFinal Accepted Versio

Del extractivismo cultural y lingüístico a la revitalización de las lenguas

Son bastante conocidos los efectos destructores de la conquista y la colonización de América sobre centenares de lenguas originarias en América Latina. Además, también se ha investigado acerca de la continuidad del proceso glotofágico bajo el dominio de las élites criollas, después de la Independencia. Durante el siglo XX, el indigenismo no cambió sustancialmente las relaciones interculturales (políticas, económicas y sociales) entre las culturas dominantes hispanófonas y las culturas minorizadas, aun cuando acumulara e hiciera uso de la simbología de las producciones precolombinas como seña de identidad nacional, de modo muy notorio en México. Sin embargo, las últimas décadas del siglo XX y los inicios del siglo XXI, a causa del neoliberalismo y la globalización, han multiplicado las amenazas sobre las culturas y las lenguas supervivientes, en la medida que se ha pretendido aniquilar el entorno medioambiental, los ecosistemas locales y el mundo vital, que podríamos categorizar como territorio indígena. El proyecto Ndatiaku Tu’un Savi es solo uno de los muchos gérmenes que pretenden revitalizar y revalorizar el conocimiento y el uso de las lenguas originarias, por medio de las redes sociales, entre sus propios hablantes, a la vez que confrontan las estrategias meramente forenses de la lingüístic
