Teaching foreign languages through audiovisual translation resources: teachers’ perspectives
In the past decade, techniques traditionally used in the audiovisual translation (AVT) industry have been applied to teaching foreign languages (FL) with promising results. Both teachers and researchers have provided useful data on various AVT typologies (i.e. subtitling, dubbing, audio description) in order to improve specific learning areas: vocabulary acquisition, listening comprehension, pronunciation, intercultural awareness, etc. (Ibáñez & Vermeulen, 2014; Baños & Sokoli, 2015). The following study aims to provide information in two relevant areas identified in the field: (1) the direct experience of those teachers who have been using AVT techniques in the classroom in recent years, and (2) their perspectives on in the combination of FL and AVT in the future. A total of 56 respondents from Europe, the USA and Asia participated in the study, these being teachers of French, English, German, Italian, Spanish, Chinese, Russian, Japanese and Catalan as an FL. The results obtained are applicable to different languages and useful to any professional interested in using AVT in their classroom or carrying out further research

Role of the Scavenger Receptor CD36 in Accelerated Diabetic Atherosclerosis
Diabetes mellitus entails increased atherosclerotic burden and medial arterial calcification, but the precise mechanisms are not fully elucidated. We aimed to investigate the implication of CD36 in inflammation and calcification processes orchestrated by vascular smooth muscle cells (VSMCs) under hyperglycemic and atherogenic conditions. We examined the expression of CD36, pro-inflammatory cytokines, endoplasmic reticulum (ER) stress markers, and mineralization-regulating enzymes by RT-PCR in human VSMCs, cultured in a medium containing normal (5 mM) or high glucose (22 mM) for 72 h with or without oxidized low-density lipoprotein (oxLDL) (24 h). The uptake of 1,1'-dioctadecyl-3,3,3',3-tetramethylindocarbocyanine perchlorate-fluorescently (DiI) labeled oxLDL was quantified by flow cytometry and fluorimetry and calcification assays were performed in VSMC cultured in osteogenic medium and stained by alizarin red. We observed induction in the expression of CD36, cytokines, calcification markers, and ER stress markers under high glucose that was exacerbated by oxLDL. These results were confirmed in carotid plaques from subjects with diabetes versus non-diabetic subjects. Accordingly, the uptake of DiI-labeled oxLDL was increased after exposure to high glucose. The silencing of CD36 reduced the induction of CD36 and the expression of calcification enzymes and mineralization of VSMC. Our results indicate that CD36 signaling is partially involved in hyperglycemia and oxLDL-induced vascular calcification in diabetes
Performance of a Quantitative PCR-Based Assay and Beta-d-Glucan Detection for Diagnosis of Invasive Candidiasis in Very-Low-Birth-Weight Preterm Neonatal Patients (CANDINEO Study)
An epidemiological, multicenter, noninterventional, observational case-control study was conducted to describe the performance of serum beta-d-glucan (BDG) and Candida PCR in blood, serum, and sterile samples for the diagnosis of invasive candidiasis (IC) in very-low-birth-weight (VLBW) preterm neonates and to compare these techniques with culture of samples from blood and other sterile sites. Seventeen centers participated in the study, and the number of episodes analyzed was 159. A total of 9 episodes of IC from 9 patients (7 confirmed and 2 probable) and 150 episodes of suspected sepsis from 117 controls were identified. The prevalence of IC was 5.7% (95% confidence interval [95% CI], 2.1 to 9.3). The mortality was significantly higher in episodes of IC (44.4%) than in the non-IC episodes (11.1%, P < 0.01). The sensitivity and specificity of the PCR performed on blood/serum samples were 87.5% and 81.6%, respectively. The sensitivity and specificity of the BDG results were lower (75.0% and 64.6%). For cases with negative culture results, the PCR and the BDG results were positive in 27 (17.4%) and 52 (33.5%) episodes, respectively. The presence of multiorgan failure, improvement with empirical antifungal therapy, thrombocytopenia, and Candida colonization were significantly associated (P < 0.01) with PCR or BDG positivity regardless of the results of the cultures. Serum BDG analysis and Candida PCR could be used as complementary diagnostic techniques to detect IC in VLBW neonates.This study was initiated and financially supported by Astellas Pharma Inc.

Star Formation Rate Indicators in Wide-Field Infrared Survey Preliminary Release
With the goal of investigating the degree to which theMIR luminosity in
theWidefield Infrared Survey Explorer (WISE) traces the SFR, we analyze 3.4,
4.6, 12 and 22 {\mu}m data in a sample of {\guillemotright} 140,000
star-forming galaxies or star-forming regions covering a wide range in
metallicity 7.66 < 12 + log(O/H) < 9.46, with redshift z < 0.4. These
star-forming galaxies or star-forming regions are selected by matching the WISE
Preliminary Release Catalog with the star-forming galaxy Catalog in SDSS DR8
provided by JHU/MPA 1.We study the relationship between the luminosity at 3.4,
4.6, 12 and 22 {\mu}m from WISE and H\alpha luminosity in SDSS DR8. From these
comparisons, we derive reference SFR indicators for use in our analysis. Linear
correlations between SFR and the 3.4, 4.6, 12 and 22 {\mu}m luminosity are
found, and calibrations of SFRs based on L(3.4), L(4.6), L(12) and L(22) are
proposed. The calibrations hold for galaxies with verified spectral
observations. The dispersion in the relation between 3.4, 4.6, 12 and 22 {\mu}m
luminosity and SFR relates to the galaxy's properties, such as 4000 {\deg}A
break and galaxy color.Comment: 10 pages, 3 figure
Microbiological contamination of conventional and reclaimed irrigation water: evaluation and management measures
The wide diversity of irrigation water sources (i.e., drinking water, groundwater, reservoir water, river water) includes reclaimed water as a requested measure for increasing water availability, but it is also a challenge as pathogen exposure may increase. This study evaluates the level of microbial contamination in different irrigation waters to improve the knowledge and analyses management measures for safety irrigation. Over a one-year period, the occurrence of a set of viruses, bacteria and protozoa, was quantified and the performance of a wetland system, producing reclaimed water intended for irrigation, was characterized. Human fecal pollution (HAdV) was found in most of the irrigation water types analysed. Hepatitis E virus (HEV), an emerging zoonotic pathogen, was present in groundwater where porcine contamination was identified (PAdV). The skin-carcinoma associated Merkel cell polyomavirus (MCPyV), was found occasionally in river water. Noroviruses were detected, as expected, in winter, in river water and reclaimed water. Groundwater, river water and reservoir water also harboured potential bacterial pathogens, like Helicobacter pylori, Legionella spp. and Aeromonas spp. that could be internalized and viable inside amoebas like Acanthamoeba castellanii, which was also detected. Neither Giardia cysts, nor any Cryptosporidium oocysts were detected. The wetland system removed 3 Log10 of viruses and 5 Log10 of bacteria, which resembled the river water quality. Irrigation waters were prone to variable contamination levels and according to the European guidance documents, the E. coli (EC) levels were not always acceptable. Sporadic detection of viral pathogens as NoV GII and HAdV was identified in water samples presenting lower EC than the established limit (100MNP/100 mL). When dealing with reclaimed water as a source of irrigation the analysis of some viral parameters, like HAdV during the peak irrigation period (summer and spring) or NoV during the coldest months, could complement existing water management tools based on bacterial indicators
A new diffuse luminous efficacy model for daylight availability in Burgos, Spain
The determination of optimal illumination conditions in buildings is of great interest both for reducing energy consumption and for exploiting solar resources with greater efficiency and sustainability. The most commonplace method of estimating daylight is the luminous efficacy approach, using the more widely measured solar irradiance. In this present study, a new model of diffuse luminous efficacy over a horizontal surface is proposed. A comparative study of twenty-two classic models is presented, to obtain diffuse illuminance, using both, the original mathematical models and the adapted models with local coefficients, in order to determine the most suitable models for Burgos, a city located in north-western Spain. With this purpose in mind, twelve models are selected for all sky conditions, five models for modelling clear sky, two for partly cloudy sky, and three for overcast sky. These twenty-two models are then compared with the new model both for all sky conditions and for particular sky conditions (clear, partly cloudy, and overcast). The behaviour of the new model showed greater accuracy than most of the classic models under analysis. Hence, the advantage of the diffuse luminous efficacy model that can be applied both to all sky and to particular sky conditions.Spanish Government (Ministerio de EconomĂa y Competitividad) (ENE2014-54601-R).

Long-Term Treatment and Effect of Discontinuation of Calcifediol in Postmenopausal Women with Vitamin D Deficiency: A Randomized Trial
Vitamin D plays a major role in bone health and probably also in multiple extraskeletal acute and chronic diseases. Although supplementation with calcifediol, a vitamin D metabolite, has demonstrated efficacy and safety in short-term clinical trials, its effects after long-term monthly administration have been studied less extensively. This report describes the results of a 1-year, phase III-IV, double-blind, randomized, controlled, parallel, multicenter superiority clinical trial to assess the efficacy and safety of monthly calcifediol 0.266 mg versus cholecalciferol 25,000 IU (0.625 mg) in postmenopausal women with vitamin D deficiency (25(OH)D < 20 ng/mL). A total of 303 women were randomized and 298 evaluated. Patients were randomized 1:1:1 to calcifediol 0.266 mg/month for 12 months (Group A1), calcifediol 0.266 mg/month for 4 months followed by placebo for 8 months (Group A2), and cholecalciferol 25,000 IU/month (0.625 mg/month) for 12 months (Group B). By month 4, stable 25(OH)D levels were documented with both calcifediol and cholecalciferol (intention-to-treat population): 26.8 ± 8.5 ng/mL (Group A1) and 23.1 ± 5.4 ng/mL (Group B). By month 12, 25(OH)D levels were 23.9 ± 8.0 ng/mL (Group A1) and 22.4 ± 5.5 ng/mL (Group B). When calcifediol treatment was withdrawn in Group A2, 25(OH)D levels decreased to baseline levels (28.5 ± 8.7 ng/mL at month 4 versus 14.4 ± 6.0 ng/mL at month 12). No relevant treatment-related safety issues were reported in any of the groups. The results confirm that long-term treatment with monthly calcifediol in vitamin D-deficient patients is effective and safe. The withdrawal of treatment leads to a pronounced decrease of 25(OH)D levels. Calcifediol presented a faster onset of action compared to monthly cholecalciferol. Long-term treatment produces stable and sustained 25(OH)D concentrations with no associated safety concerns.This study was funded by Faes Farma, S.A. and Bruno Farmaceutici S.p.A.

SHARDS frontier fields: physical properties of a low-mass Lyα emitter at z = 5.75
We analyze the properties of a multiply-imaged Lyman-alpha (Lya) emitter at
z=5.75 identified through SHARDS Frontier Fields intermediate-band imaging of
the Hubble Frontier Fields (HFF) cluster Abell 370. The source, A370-L57, has
low intrinsic luminosity (M_UV~-16.5), steep UV spectral index
(\beta=-2.4+/-0.1), and extreme rest-frame equivalent width of Lya
(EW(Lya)=420+180-120 \AA). Two different gravitational lens models predict high
magnification (\mu~10--16) for the two detected counter-images, separated by
7", while a predicted third counter-image (\mu~3--4) is undetected. We find
differences of ~50% in magnification between the two lens models, quantifying
our current systematic uncertainties. Integral field spectroscopy of A370-L57
with MUSE shows a narrow (FWHM=204+/-10 km/s) and asymmetric Lya profile with
an integrated luminosity L(Lya)~10^42 erg/s. The morphology in the HST bands
comprises a compact clump (r_e<100 pc) that dominates the Lya and continuum
emission and several fainter clumps at projected distances <1 kpc that coincide
with an extension of the Lya emission in the SHARDS F823W17 and MUSE
observations. The latter could be part of the same galaxy or an interacting
companion. We find no evidence of contribution from AGN to the Lya emission.
Fitting of the spectral energy distribution with stellar population models
favors a very young (t<10 Myr), low mass (M*~10^6.5 Msun), and metal poor
(Z<4x10^-3) stellar population. Its modest star formation rate (SFR~1.0
Msun/yr) implies high specific SFR (sSFR~2.5x10^-7 yr^-1) and SFR density
(Sigma_SFR ~ 7-35 Msun/yr/kpc^2). The properties of A370-L57 make it a good
representative of the population of galaxies responsible for cosmic
reionization.Comment: 14 pages, 8 figures, 4 tables. Accepted for publication in Ap
Novel synthetic sulfoglycolipid IG20 facilitates exocytosis in chromaffin cells through the regulation of sodium channels
This is the peer reviewed version of the following article: Novel synthetic sulfoglycolipid IG20 facilitates exocytosis in
chromaffin cells through the regulation of sodium channels: Journal of Neurochemistre, 135.5 (2015), which has been published in final form at http://dx.doi.org/10.1111/jnc.13357In searching for druggable synthetic lipids as potential modulators of synaptic transmission and
plasticity, we synthesized sulfoglycolipid IG20 that stimulates neuritic outgrowth. Here we have
explored its effects on ion channels and exocytosis in bovine chromaffin cells (BCCs). IG20
augmented the rate of basal catecholamine release. Such effect did not depend on Ca2+ mobilization
from intracellular stores; rather, IG20-elicited secretion entirely dependent on Ca2+ entry through Lsubtype
voltage-activated Ca2+ channels. Those channels were recruited by cell depolarization
mediated by IG20 likely through its ability to enhance the recruitment of Na+ channels at more
hyperpolarizing potentials. Confocal imaging with fluorescent derivative IG20-NBD revealed its rapid
incorporation and confinement into the plasmalemma, supporting the idea that IG20 effects are exerted
through a plasmalemmal-delimited mechanism. Thus, synthetic IG20 seems to mimic several
physiological effects of endogenous lipids such as regulation of ion channels, Ca2+ signaling, and
exocytosis. Therefore, sulfoglycolipid IG20 may become a pharmacological tool to investigate the role
of the lipid environment on neuronal excitability, ion channels, neurotransmitter release, synaptic
efficacy, and neuronal plasticity. It may also inspire the synthesis of druggable sulfoglycolipids aimed
at increasing synaptic plasticity and efficacy in neurodegenerative diseases and traumatic brain –
