Caribbean Children\u27s Music Rhythms, Melodies, and Lyrics Lecture by Marta Hernández Candelas

Children\u27s songs are a natural way to play and communicate with children around the world. A child can understand his or her world better and share emotions while singing with friends and caretakers.The purpose of this presentation is to share the findings of the author\u27s research at the Dfaz-Ayala Music Collection at FIU about Caribbean children\u27s songs. The talk wil emphasize songs for preschoolers and their possibilities of being adapted for instrumental playing as well as for family-based music education programs. Finding Cuban children\u27s songs has not been an easy task. They should be shared in the same manner as other forms of popular music.

2b-RAD genotyping for population genomic studies of Chagas disease vectors: Rhodnius ecuadoriensis in Ecuador

Background: Rhodnius ecuadoriensis is the main triatomine vector of Chagas disease, American trypanosomiasis, in Southern Ecuador and Northern Peru. Genomic approaches and next generation sequencing technologies have become powerful tools for investigating population diversity and structure which is a key consideration for vector control. Here we assess the effectiveness of three different 2b restriction site-associated DNA (2b-RAD) genotyping strategies in R. ecuadoriensis to provide sufficient genomic resolution to tease apart microevolutionary processes and undertake some pilot population genomic analyses. Methodology/Principal findings: The 2b-RAD protocol was carried out in-house at a non-specialized laboratory using 20 R. ecuadoriensis adults collected from the central coast and southern Andean region of Ecuador, from June 2006 to July 2013. 2b-RAD sequencing data was performed on an Illumina MiSeq instrument and analyzed with the STACKS de novo pipeline for loci assembly and Single Nucleotide Polymorphism (SNP) discovery. Preliminary population genomic analyses (global AMOVA and Bayesian clustering) were implemented. Our results showed that the 2b-RAD genotyping protocol is effective for R. ecuadoriensis and likely for other triatomine species. However, only BcgI and CspCI restriction enzymes provided a number of markers suitable for population genomic analysis at the read depth we generated. Our preliminary genomic analyses detected a signal of genetic structuring across the study area. Conclusions/Significance: Our findings suggest that 2b-RAD genotyping is both a cost effective and methodologically simple approach for generating high resolution genomic data for Chagas disease vectors with the power to distinguish between different vector populations at epidemiologically relevant scales. As such, 2b-RAD represents a powerful tool in the hands of medical entomologists with limited access to specialized molecular biological equipment. Author summary: Understanding Chagas disease vector (triatomine) population dispersal is key for the design of control measures tailored for the epidemiological situation of a particular region. In Ecuador, Rhodnius ecuadoriensis is a cause of concern for Chagas disease transmission, since it is widely distributed from the central coast to southern Ecuador. Here, a genome-wide sequencing (2b-RAD) approach was performed in 20 specimens from four communities from Manabí (central coast) and Loja (southern) provinces of Ecuador, and the effectiveness of three type IIB restriction enzymes was assessed. The findings of this study show that this genotyping methodology is cost effective in R. ecuadoriensis and likely in other triatomine species. In addition, preliminary population genomic analysis results detected a signal of population structure among geographically distinct communities and genetic variability within communities. As such, 2b-RAD shows significant promise as a relatively low-tech solution for determination of vector population genomics, dynamics, and spread

A quantitative approach to assess histopathological changes in the trachea of dogs and pigs infected with Influenza Virus using an ex vivo organ culture system

Histopathology is a widely used method to assess the diagnosis of a variety of diseases and pathological conditions, and achieving a diagnosis is considered the ultimate aim in most cases, in order to prevent and/or treat possible diseases. Nevertheless, when it comes to research, the simple assessment of presence/absence of alteration is not considered precise enough, and a rigorous evaluation of affected tissues is needed, taking into account time-dependent factors and accurate determination of the severity of the changes in an unbiased way. Recent developments on image analysis software can reduce subjectivity and give the possibility to convert images into measurements which are in turn suitable for statistical analyses. The purpose of this thesis was to explore the possibility of quantifying pathological changes using an unbiased method, using an image software (Image J). In that sense, a study was designed to test Image J on a previously used ex vivo organ culture (EVOC) system represented by canine and swine tracheal explants infected with canine influenza virus (CIV) and swine influenza virus (SIV), respectively. While the role of the pathologist is still considered as an essential figure to develop the experiment and interpreting the results, Image J allowed the measurement of different parameters using immunohistochemistry (IHC) and H&E stains, allowing quantification of different pathological changes caused by influenza virus at different points of infection (from day 0 to day 4). These parameters were area of epithelium, apoptosis (cleaved caspase-3), innate immunity (Mx1), and regeneration (ki67). The results obtained in this study revealed changes consistent with epithelial loss, increased numbers of apoptotic cells, and regeneration in CIV- and SIV-infected tracheal explants, compared to non-infected ones

Monitorización de las cargas de entrenamiento en corredores de fondo y medio fondo de alto nivel

El principal objetivo del entrenamiento consiste en mejorar el rendimiento y, por ende, reducir lesiones. Para ello, la monitorización de dicha carga (interna, externa y su relación) se ha constatado como vital. Sin embargo, muchos entrenadores siguen sin controlar (o etéreamente) las cargas en sus deportistas, pues, además, no existe un sistema etiquetado como el ideal. Consecuentemente, teniendo en cuenta el contexto y lo que la literatura dice al respecto, se realizó una propuesta personal con corredores de resistencia de alto nivel, contabilizando, en cuanto a carga externa, volumen mediante los kilómetros recorridos semanalmente, intensidad mediante la velocidad de carrera con zonas de entrenamiento en función del perfil individual de lactato, y frecuencia registrando el número de entrenamientos y de los contenidos trabajados. Respecto al estrés interno, la Escala de Esfuerzo Percibido y la medición de la altura del salto vertical con contramovimiento, en pos de determinar la fatiga neuromuscular subaguda. Los resultados mostraron relación significativa en la mayoría de variables, haciendo que el objetivo e hipótesis que perseguía la intervención se cumplan en mayor o menor medida, por lo que el sistema de monitorización escogido y/o los diferentes ítems que lo componen podrían ser válidos para su utilización en otros contextos.The main objective of training is to improve performance and, therefore, reduce injuries. For that reason, the monitoring of this load (internal, external and their relationship) has been verified as vital. However, many trainers still do not control (or ethereally) the loads on their athletes. In addition, there is not system labeled as the ideal. Consequently, taking into account the context and what the literature says about it, a personal research was made with high-level resistance runners, accounting, in terms of external load, volume through the kilometers traveled weekly, intensity through the running speed with training zones depending on the individual lactate profile, and frequency recording the number of training sessions and the contents worked. Regarding internal stress, the Rating of Perceived Exertion and a measurement of countermovement jump height, in order to determine subacute neuromuscular fatigue. The results showed a significant relationship in most variables, making the objective and hypothesis of the intervention have been met to a greater or lesser extent, so that the chosen monitoring system and / or the different items that comprise it could be valid for its use in other contexts.info:eu-repo/semantics/publishedVersio

Nanostructured Hybrids Based on Tantalum Bromide Octahedral Clusters and Graphene Oxide for Photocatalytic Hydrogen Evolution

[EN] The generation of hydrogen (H2) using sunlight has become an essential energy alternative for decarbonization. The need for functional nanohybrid materials based on photo- and electroactive materials and accessible raw materials is high in the field of solar fuels. To reach this goal, single-step synthesis of {Ta6Bri12}@GO (GO = graphene oxide) nanohybrids was developed by immobilization of [{Ta6Bri12}Bra2(H2O)a4]·4H2O (i = inner and a = apical positions of the Ta6 octahedron) on GO nanosheets by taking the advantage of the easy ligand exchange of the apical cluster ligands with the oxygen functionalities of GO. The nanohybrids were characterized by spectroscopic, analytical, and morphological techniques. The hybrid formation enhances the yield of photocatalytic H2 from water with respect to their precursors and this is without the presence of precious metals. This enhancement is attributed to the optimal cluster loading onto the GO support and the crucial role of GO in the electron transfer from Ta6 clusters into GO sheets, thus suppressing the charge recombination. In view of the simplicity and versatility of the designed photocatalytic system, octahedral tantalum clusters are promising candidates to develop new and environmentally friendly photocatalysts for H2 evolution.This research was funded by Ministerio de Ciencia e Innovación (MICINN), grant number PGC2018-099744.

Análisis del golpeo y la preparación psicológica para retornar a la práctica en futbolistas tras una lesión isquiosural

Las lesiones de la musculatura isquiosural son las más comunes en fútbol, y pueden presentar efectos residuales que cambien el patrón de un gesto técnico. El presente estudio analizó las diferencias en la técnica de golpeo entre jugadores anteriormente lesionados y jugadores no lesionados, así como las correlaciones entre la capacidad psicológica para retornar a la práctica y las características del gesto. Tres futbolistas que habían padecido una lesión de isquiosurales conformaron el grupo de jugadores anteriormente lesionados, y tres futbolistas que no habían padecido ninguna lesión en el miembro inferior en los últimos dos años, formaron el grupo de jugadores no lesionados. Se analizaron los gestos de golpeo a balón parado y de golpeo en carrera a través del programa Kinovea. Asimismo, se evaluó la capacidad psicológica para retornar a la práctica mediante el Injury Psychological Readiness to Return to Sport (I-PRRS). Únicamente la velocidad del balón en el golpeo en carrera presentó diferencias significativas entre grupos (p<0,05). Además, se obtuvieron correlaciones positivas entre la preparación psicológica para retornar y la flexión de rodilla en el golpeo en carrera, y entre la flexión de rodilla en el golpeo a balón parado y los ítems 3 y 4 del I-PRRS. Asimismo, se hallaron correlaciones negativas entre la extensión de cadera en el golpeo a balón parado y el ítem 6 del I-PRRS. Los resultados permiten concluir que variables cinemáticas y variables psicológicas se encuentran interrelacionadas tras una lesión en la musculatura isquiosural.info:eu-repo/semantics/publishedVersio

Open-Access Publishing in Tourism and Hospitality Research

This paper examines various models of academic publishing and considers their relative advantages for authors, readers, academic institutions and society. Relevant factors driving authors\u27 choice of the journal include the journal\u27s scope, reputation and publishing model used. Authors\u27 choices are shaped by the expectations of academic institutions and strongly determine both access to readers and the benefits to society. From an analysis of 174 journals in the tourism and hospitality field, four publication models are identified and compared: \u27subscription-only\u27 and the \u27Green\u27, \u27Gold\u27 and \u27Platinum\u27 open-access models. The findings of a survey of 42 editors of journals in the field are then presented. These suggest that subscription-based journals (subscription-only or hybrid) tend to be owned by commercial publishing companies and have the highest reputation, as measured by their position in one or more indexing systems. They also tend to have significantly larger paper submissions than open-access journals, especially those that use the Platinum open-access model. While some commentators have suggested that editors of open-access journals with article-processing charges may be tempted to lower their scientific standards to maximize revenues, no evidence was found that such journals have higher acceptance rates than their subscription-based equivalents
