Early Word Comprehension in Infants: Replication and Extension.

A handful of recent experimental reports have shown that infants of 6 to 9 months know the meanings of some common words. Here, we replicate and extend these findings. With a new set of items, we show that when young infants (age 6-16 months, n=49) are presented with side-by-side video clips depicting various common early words, and one clip is named in a sentence, they look at the named video at above-chance rates. We demonstrate anew that infants understand common words by 6-9 months, and that performance increases substantially around 14 months. The results imply that 6-9 month olds' failure to understand words not referring to objects (verbs, adjectives, performatives) in a similar prior study is not attributable to the use of dynamic video depictions. Thus, 6-9 month olds' experience of spoken language includes some understanding of common words for concrete objects, but relatively impoverished comprehension of other words.

RNA Localization and Translational Regulation on the Endoplasmic Reticulum

mRNA localization is emerging as a critical cellular mechanism for the spatiotemporal regulation of protein expression and serves important roles in oogenesis, embryogenesis, cell fate specification, and synapse formation. Signal sequence-encoding mRNAs are localized to the endoplasmic reticulum (ER) membrane by either of two mechanisms, a canonical mechanism of translation on ER-bound ribosomes (signal recognition particle pathway), or a poorly understood direct ER anchoring mechanism. In this study, we identify that the ER integral membrane proteins function as RNA-binding proteins and play important roles in the direct mRNA anchoring to the ER. We report that one of the ER integral membrane RNA-binding protein, AEG-1 (astrocyte elevated gene-1), functions in the direct ER anchoring and translational regulation of mRNAs encoding endomembrane transmembrane proteins. HITS-CLIP and PAR-CLIP analyses of the AEG-1 mRNA interactome of human hepatocellular carcinoma cells revealed a high enrichment for mRNAs encoding endomembrane organelle proteins, most notably encoding transmembrane proteins. AEG-1 binding sites were highly enriched in the coding sequence and displayed a signature cluster enrichment downstream of encoded transmembrane domains. In overexpression and knockdown models, AEG-1 expression markedly regulates translational efficiency and protein functions of two of its bound transcripts, MDR1 and NPC1. This study reveals a molecular mechanism for the selective localization of mRNAs to the ER and identifies a novel post-transcriptional gene regulation function for AEG-1 in membrane protein expression.

Geochemistry of basalts from the Caribbean Large Igneous Province

Oceanic flood basalts are poorly understood, short-term expressions of highly increased heat flux and mass flow within the convecting mantle. The uniqueness of the Caribbean Large Igneous Province (CLIP, 92-74 Ma) with respect to other Cretaceous oceanic plateaus is its extensive sub-aerial exposures, providing an excellent basis to investigate the temporal and compositional relationships within a starting plume head. We present major element, trace element and initial Sr-Nd-Pb isotope composition of 40 extrusive rocks from the Caribbean Plateau, including onland sections in Costa Rica, Colombia and Curaçao as well as DSDP Sites in the Central Caribbean. Even though the lavas were erupted over an area of ~3*10**6 km**2, the majority have strikingly uniform incompatible element patterns (La/Yb=0.96+/-0.16, n=64 out of 79 samples, 2sigma) and initial Nd-Pb isotopic compositions (e.g. 143Nd/144Ndin=0.51291+/-3, epsilon-Nd i=7.3+/-0.6, 206Pb/204Pbin=18.86+/-0.12, n=54 out of 66, 2sigma). Lavas with endmember compositions have only been sampled at the DSDP Sites, Gorgona Island (Colombia) and the 65-60 Ma accreted Quepos and Osa igneous complexes (Costa Rica) of the subsequent hotspot track. Despite the relatively uniform composition of most lavas, linear correlations exist between isotope ratios and between isotope and highly incompatible trace element ratios. The Sr-Nd-Pb isotope and trace element signatures of the chemically enriched lavas are compatible with derivation from recycled oceanic crust, while the depleted lavas are derived from a highly residual source. This source could represent either oceanic lithospheric mantle left after ocean crust formation or gabbros with interlayered ultramafic cumulates of the lower oceanic crust. High 3He/4He in olivines of enriched picrites at Quepos are ~12 times higher than the atmospheric ratio suggesting that the enriched component may have once resided in the lower mantle. Evaluation of the Sm-Nd and U-Pb isotope systematics on isochron diagrams suggests that the age of separation of enriched and depleted components from the depleted MORB source mantle could have been <=500 Ma before CLIP formation and interpreted to reflect the recycling time of the CLIP source. Mantle plume heads may provide a mechanism for transporting large volumes of possibly young recycled oceanic lithosphere residing in the lower mantle back into the shallow MORB source mantle.

Care home managers’ knowledge of palliative care: a Northern Irish study

Efficient and Selectable Production of Reactive Species Using a Nanosecond Pulsed Discharge in Gas Bubbles in Liquid

A plasma gas bubble-in-liquid method for high production of selectable reactive species using a nanosecond pulse generator has been developed. The gas of choice is fed through a hollow needle in a point-to-plate bubble discharge, enabling improved selection of reactive species. The increased interface reactions, between the gas-plasma and water through bubbles, give higher productivity. H₂O₂ was the predominant species produced using Ar plasma, while predominantly  and NO₂ were generated using air plasma, in good agreement with the observed emission spectra. This method has nearly 100% selectivity for H₂O₂, with seven times higher production, and 92% selectivity for , with nearly twice the production, compared with a plasma above the water.

Paraneoplastic syndromes

Abstract: There are two types of clinical and biochemical syndromes not directly associated with the invasiveness and metastatic ability of the tumour; the first type is represented by the hormonal paraneoplastic syndromes. The second type consists of certain neurological diseases or abnormalities observed in patients with malignant tumours not directly affecting the nervous system. While the hormonal type is well established and rests on solid ground, the neurological type is less well defined and more controversial. © 1981 Pergamon Press Ltd.

Hongos entomopátogenos para el control de mosca blanca Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) en el cultivo de chile dulce (Capsicum annuum L.) bajo condiciones protegidas

El chile dulce (Capsicum annuum L.) es una de las hortalizas que utilizan grandes inversiones en su manejo y producción. En El Salvador, HIDROEXPO, S.A. de C.V es una de las empresas con sistemas de producción hidropónica y de cultivo protegido de chile dulce o pimentón, orientado al mercado internacional. Sin embargo, a pesar de la tecnología empleada y las estructuras de protección, siempre existe la aparición de plagas y enfermedades. La mosca blanca Bemisia tabaci (Genn.), es uno de los principales insectos que ocasiona pérdidas en cultivos hortícolas. El principal problema fitosanitario ocasionado por la Bemisia tabaci (Genn.) se da al servir como vector de geminivirus, los cuales ocasionan pérdidas importantes en la mayoría de cultivos hortícolas y leguminosas. El objetivo de la presente investigación fue evaluar hongos entomopátogenos como alternativa en la reducción de la población de ninfas de Bemisia tabaci (Genn.), para su utilización en programas MIP. La investigación se realizó de agosto 2014 a noviembre 2015. La primera fase fue de laboratorio, realizando la reproducción, pruebas de viabilidad, pureza y agresividad del hongo Beauveria brongniartii. Luego se realizó la fase de campo en instalaciones protegidas brindadas por CENTA donde se montó el área de trabajo con plantas de chile pimentón, evaluando cuatro cepas de hongos entomopátogenos a la concentración de 1x105: Beauveria bassiana, Beauveria brongniartii, Isaria fumorosea y Lecanicillium lecanii, utilizando un diseño completamente al azar (DCA) con cinco repeticiones, tomando como variables la mortalidad mediante un análisis ANVA.

La CL50 de la cepa de B. brogniartiise estimó en 5 x 107 conidios por ml y la CL90 en 1 x 108 conidios por ml. Demostrando que los hongos entomopátogenos son una buena alternativa de control biológico contra Bemisia tabaco (Genn.). Palabras clave: Mosca blanca, Bemisia tabaci (Genn.), hongos entomopátogenos, chile dulce, Capsicum annuum, control biológico.

Teaching psychology to student nurses: the use of ‘Talking Head’ videos

Psychology is a central part of undergraduate nursing curricula in the UK. However, student nurses report difficulties recognising the relevance and value of psychology. We sought to strengthen first-year student nurses’ application of psychology by developing a set of digital stories based around ‘Talking Head’ video clips where authentic patients relate their experiences of illness and nursing care. The aim of this article is to discuss the technological, organisational and pedagogical challenges, student and staff evaluations and our recommendations for the future of Talking Heads. First-year student nurses were shown a video clip of a patient talking about their illness experiences followed by a group learning situation linking main themes to psychology and nursing. Students and staff valued the authenticity of patient's narrative, found the video clip easy to follow, reported a raised awareness of psychological concepts and improved empathetic understanding of chronic illness. Negative evaluations were related to a sanitised, untypical representation and limited internet access. This small-scale study highlighted how patient narrative may enhance students understanding of illness experience. It chronicles the development and evaluation of a Talking Head in a specific context but which may be useful across disciplines.

Audience attitudes towards simil sync: a pilot study

This thesis is based on a pilot investigation which explores the attitudes of a sample of Italian viewers towards the simil sync technique which in Italy is used for the dub of non-fictional television contents. The thesis seeks to analyse and define the characteristics of this dubbing modality which is often considered by scholars and professionals in the dubbing industry a hybrid modality of standard synchronised dubbing and voice-over. In order to investigate viewers’ attitudes, I organised 4 focus groups sessions which, due to the impact of Covid-19 pandemic, were carried out online. The online recruitment of participants, which was a difficult task, resulted in a small sample of eighteen participants (and two interviewees). The four online focus groups revealed that participants were aware of the simil sync technique. They recognised that the clips were dubbed in a different modality from standard synchronised dubbing. The characteristic that was mostly mentioned for detecting simil sync was the original soundtrack that was audible below the dub, followed by the identification of the genre of the programme in the clip and the absence of lip sync. Moreover, while simil sync with a barely audible original soundtrack received neutral or positive attitudes, simil sync with a more audible original soundtrack, instead, was tolerated or considered annoying. Simil sync passed unnoticed in the in-depth interviews in which the discussion about dubbing was not focused on the distinction between two dubbing modalities, for instance simil sync versus standard synchronised dubbing, but rather on the distinction between programmes that originated in Italian and those that were translated into Italian from another language and then dubbed.

Quantitative analysis of pre- and post-operative valvular annulus deformations following valvular insufficiency

Valvular insufficiency is a growingly common valvular heart disease that frequently is associated with regurgitation. Atrioventricular incompetency can lead to overall ventricular and atrial enlargement, volume overload, heart impairment and, if not treated, can culminate in heart failure. With the advances in technology and the increasing interest in devices that have lower post-operative burden on patients, transcatheter mitral and tricuspid valve repair systems are going through a phase of rapid development and growing use. In this work, we aimed to quantitatively assess the morphology of mitral and tricuspid annuli in patients who underwent transcatheter valve repair with MitraClip/TriClip, before and after the intervention, using three-dimensional transoesophageal echocardiography images, in order to evaluate the geometrical changes of the annulus following the intervention. For our purposes, firstly, we implemented a tool for the visualization and navigation of the volumetric data across the cardiac cycle. Then, in order to track the annulus over the cardiac cycle, we extracted five rotational slices from the volume data, selected two initial points on each slice, and tracked these points across the cardiac cycle using KLT algorithm. In a first stage we led a parameters optimization for the tracking method, and we studied the sensitivity of the KLT algorithm to the initialization points, that are manually chosen by the user. In a second stage, we analysed 10 subjects (5 for mitral regurgitation and 5 for tricuspid regurgitation), tracking their annulus before and after valve repairment. In conclusion, we found in all our 10 subjects that immediately after the intervention there is a shortening of the major diameters of the valves, mainly the shortest diameter, due to the clip application, that leads to a reduction of the perimeter and the area of the annulus.
