Adaptación al Español Europeo de la Evaluación Automatizada de la Memoria Operativa (Automated Working Memory Test Battery -AWMA).

The current study presents the adaptation of Automated Working Memory Assessment into European Spanish, considering the need of calibration for accent and linguistic issues not supported by the version available. For this purpose, verbal material was carefully and properly selected, considering specificities of the European Spanish, in order to control possible effects of psycholinguistic factors, such as word length or lexical frequency, and technical aspects such as stimuli presentation speed and sound quality were also tuned. An exploratory sample of 81 children from 7- to 9-year-old was assessed to confirm that the adaptation is suitable for further use, besides, their scores were contrasted with the Argentinean children. The data showed proper validity and reliability scores, which characterize this version as a useful instrument for research purposes, and its usage in further studies should be encourage to gather normative data for Spaniards.En el presente estudio se presenta la adaptación al idioma Es-pañol Europeo de la Evaluación Automatizada de la Memoria Operativa, habiéndose tenido en cuenta la necesidad de calibración para cuestiones de acento y lingüística que no son compatibles con la versión disponible. Con este propósito, el material verbal fue seleccionado cuidadosa y apropiada-mente, teniendo en cuenta las especificidades del Español Europeo y con el fin de controlar los posibles efectos de los factores psicolingüísticos, tales como la longitud de las palabras o la frecuencia léxica, y aspectos técnicos, como la velocidad de presentación de los estímulos y la calidad de sonido también fueron controlados. Una muestra exploratoria de 81 niños de 7 a 9 años de edad se evaluó para confirmar que la adaptación es adecuada para su empleo posterior. Además las puntuaciones obtenidas se contrastaron con las de niños argentinos. Los datos mostraron una validez adecuada y una puntuación fiable, lo que permite considerar a esta versión como un instrumento útil para fines de investigación, y su empleo en futuros estu-dios debería incentivar la recopilación de datos normativos para españoles.This research was supported mainly by two grants from the Fundacion Seneca, Murcia Regional Government Agency for Science and Technology (visiting research grant 2010 to Flavia Heloisa Dos Santos and research grant 19463/PI/14), and by a grant from the Spanish Minister of Science and Innovation (research grant PSI2008-03481/PSIC)

Hybrid molecules of protoflavones and spirooxindole derivatives with selective cytotoxicity against triple-negative breast cancer cells

The combination of compounds with complementary bioactivities into hybrid molecules is an emerging concept in drug discovery. In this study, we aimed to synthesize new hybrid compounds based on p53-MDM2/X protein-protein interaction spiropyrazoline oxindole-based inhibitors and ataxia telangiectasia and Rad3-related (ATR) protoflavone-based inhibitors through copper(i) catalysed azide-alkyne cycloaddition. Five new hybrids were prepared along with three representative reference fragments. The compounds were tested against human breast cancer cell lines MCF-7 (hormone-dependent, wild-type p53) and MDA-MB-231 (triple-negative, mutant p53). Most of the new hybrids were more cytotoxic than their reference fragments and several showed 2-4 times selective toxicity against MDA-MB-231 cells. Relevant pharmacological benefit gained from the hybrid coupling was further confirmed by virtual combination index calculations using the Chou method. Compound 13 modulated doxorubicin-induced DNA damage response through inhibiting the ATR-dependent activation of Chk-1, while increasing the activation of Chk-2. Our results suggest that the new hybrids may serve as new leads against triple negative breast cancer

Microbial communities in marine environments are ecologically relevant as intermediaries of energy, and play an important role in nutrient regeneration cycles as decomposers of dead and decaying organic matter. In this sense, marine-derived fungi can be considered as a source of enzymes of industrial and/or environmental interest. Fungal strains isolated from different substrates, such as invertebrates, decaying wood, seawater, sediments, and mangrove detritus, have been reported to be producers of hydrolytic and/or oxidative enzymes, with alginate lyase, amylase, cellulase, chitinase, glucosidase, inulinase, keratinase, ligninase, lipase, nuclease, phytase, protease, and xylanase being among the enzymes produced by fungi of marine origin. These enzymes present temperature and pH optima ranging from 35 to 70 degrees C, and 3.0 to 11.0, respectively. High-level production in bioreactors is mainly performed using submerged-state fermentation. Certain marine-derived fungal strains present enzymes with alkaline and cold-activity characteristics, and salinity is considered an important condition in screening and production processes. The adaptability of marine-derived fungi to oceanic conditions can be considered an attractive point in the field of fungal marine biotechnology. In this review, we focus on the advances in discovering enzymes from marine-derived fungi and their biotechnological relevance.6Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)FAPESP [2013/19486-0, 2013/08617-7]CNPq [304103/2013-6, 301248/2010-9]FAPESP [FAPESP 2009/18399-1, FAPESP 2011/18769-3, FAPESP 2008/06720-7, FAPESP 2012/12622-3, FAPESP 2013/12505-0, FAPESP 2014/12430-2, CNPq 159488/2014, FAPESP 2013/00286-1

Enhanced stability of perovskite solar cells incorporating dopant-free Crystalline spiro-OMeTAD layers by vacuum sublimation

The main handicap still hindering the eventual exploitation of organometal halide perovskite-based solar cells is their poor stability under prolonged illumination, ambient conditions, and increased temperatures. This article shows for the first time the vacuum processing of the most widely used solid-state hole conductor (SSHC), i.e., the Spiro-OMeTAD [2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenyl-amine) 9,9′-spirobifluorene], and how its dopant-free crystalline formation unprecedently improves perovskite solar cell (PSC) stability under continuous illumination by about two orders of magnitude with respect to the solution-processed reference and after annealing in air up to 200 °C. It is demonstrated that the control over the temperature of the samples during the vacuum deposition enhances the crystallinity of the SSHC, obtaining a preferential orientation along the π–π stacking direction. These results may represent a milestone toward the full vacuum processing of hybrid organic halide PSCs as well as light-emitting diodes, with promising impacts on the development of durable devices. The microstructure, purity, and crystallinity of the vacuum sublimated Spiro-OMeTAD layers are fully elucidated by applying an unparalleled set of complementary characterization techniques, including scanning electron microscopy, X-ray diffraction, grazing-incidence small-angle X-ray scattering and grazing-incidence wide-angle X-ray scattering, X-ray photoelectron spectroscopy, and Rutherford backscattering spectroscopy.The authors thank the “Agencia Estatal de Investigación”, “Consejería de Economía y Conocimiento de la Junta de Andalucía” (US‐1263142), “Ministerio de Economía y Competitividad” (MAT2016‐79866‐R, MAT2013‐42900‐P, FPA2016‐77689‐C2‐1‐R, and MAT2016‐76892‐C3‐2‐R) and the European Union (EU) through cohesion fund and FEDER 2014‐2020 programs for financial support.

Science CONOPS for Application of SPORT Mission Data to Study Large (~1000km) Ionospheric Plasma Depletions

The Scintillation Prediction Observations Research Task (SPORT) mission is a single 6U CubeSat space weather satellite planned for an October 2022 launch into an ISS-like orbit. The primary purpose of the SPORT mission is to determine the longitudinal effects on equatorial plasma bubble (EPB) growth resulting from the offset dipole magnetic field of the Earth. By combining field and plasma measurements from SPORT with other low-altitude (i.e., alt \u3c 1000 km) spacecraft, it is possible to investigate large-scale (\u3e 1000 km) EPB structures. The types of investigation made possible by measurements from SPORT and other contemporaneous missions include 1) dynamics of depleted magnetic flux tubes; 2) dynamics of field-aligned EPB expansion versus propagation speed; 3) EPB vertical extent; and 4) EPB temporal evolution. To support these investigation types, the respective modes of conjunctions are: 1) simultaneous intersection of a magnetic flux tube; 2) intersection of magnetic flux tube separated in time; 3) Simultaneous Latitude/Longitude position conjunction; and 4) Non-simultaneous latitude/longitude position conjunction. This paper will summarize the SPORT satellite and data used for Science CONOPS to accomplish these objectives

Communication in health practices: integrative literature review

Objectivethis study aims to describe the main thematic axes explored in the communication field in health practices in the scenarios of the Unified Health System (SUS). Methodintegrative literature review conducted by means of search for articles in the databases Latin American Literature on Health Sciences (LILACS), International Literature on Health Sciences (MedLine), and Science Direct, using the descriptors: health communication or communication. A crossing of the descriptors communication and health education was provided. Resultfour themes were constructed: 1) communication to establish relationships between health professionals and users; 2) (in)communication: barriers to the communicative act, 3) communication and health professional education; and 4) communicative health models: search for the dialogic model. Conclusionby understanding dialogic communication, which must be observed in communication, the new requirements posed by the legalization of SUS have shown weaknesses of the single-line and vertical communication model and the need to provide health professionals, since the undergraduate course, with knowledge that enable dialogic communication practices. The challenge of reflective and participatory experiences in the various health care settings still remains, in order to promote a sharing of knowledge that leads to understanding between the interlocutors involved in the communicative act.Objetivoeste artigo tem por objetivo descrever os principais eixos temáticos explorados no campo da comunicação nas práticas em saúde nos cenários do Sistema Único de Saúde (SUS).

The Lamb shift in muonic hydrogen and the proton radius

By means of pulsed laser spectroscopy applied to muonic hydrogen (μ− p) we have measured the 2S F = 1 1/2 − 2PF = 2 3/2 transition frequency to be 49881.88(76) GHz. By comparing this measurement with its theoretical prediction based on bound-state QED we have determined a proton radius value of rp = 0.84184 (67) fm. This new value is an order of magnitude preciser than previous results but disagrees by 5 standard deviations from the CODATA and the electronproton scattering values. An overview of the present effort attempting to solve the observed discrepancy is given. Using the measured isotope shift of the 1S-2S transition in regular hydrogen and deuterium also the rms charge radius of the deuteron rd = 2.12809 (31) fm has been determined. Moreover we present here the motivations for the measurements of the μ 4He + and μ 3He + 2S-2P splittings. The alpha and triton charge radii are extracted from these measurements with relative accuracies of few 10 − 4. Measurements could help to solve the observed discrepancy, lead to the best test of hydrogen-like energy levels and provide crucial tests for few-nucleon ab-initio theories and potentials

Diagnosis and management in Rubinstein-Taybi syndrome:first international consensus statement

Rubinstein-Taybi syndrome (RTS) is an archetypical genetic syndrome that is characterised by intellectual disability, well-defined facial features, distal limb anomalies and atypical growth, among numerous other signs and symptoms. It is caused by variants in either of two genes (CREBBP, EP300) which encode for the proteins CBP and p300, which both have a function in transcription regulation and histone acetylation. As a group of international experts and national support groups dedicated to the syndrome, we realised that marked heterogeneity currently exists in clinical and molecular diagnostic approaches and care practices in various parts of the world. Here, we outline a series of recommendations that document the consensus of a group of international experts on clinical diagnostic criteria for types of RTS (RTS1: CREBBP; RTS2: EP300), molecular investigations, long-term management of various particular physical and behavioural issues and care planning. The recommendations as presented here will need to be evaluated for improvements to allow for continued optimisation of diagnostics and care.</p
