APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge

The central (‘bulge’) region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen (12C 14N). Some of these objects, which are also known as nitrogen-enhanced stars, are hypothesised to be relics of the ancient assembly history of the Milky Way. Although the chemical similarity of nitrogen-enhanced stars to the unique chemical patterns observed in globular clusters has been observed, a direct connection between field stars and globular clusters has not yet been proven. In this work, we report on high-resolution, near-infrared spectroscopic observations of the bulge globular cluster NGC 6723, and the serendipitous discovery of a star, 2M18594405−3651518, located outside the cluster (near the tidal radius) but moving on a similar orbit, providing the first clear piece of evidence of a star that was very likely once a cluster member and has recently been ejected. Its nitrogen abundance ratio ([N/Fe] & +0.94) is well above the typical Galactic field-star levels, and it exhibits noticeable enrichment in the heavy s-process elements (Ce, Nd, and Yb), along with moderate carbon enrichment; all characteristics are known examples in globular clusters. This result suggests that some of the nitrogen-enhanced stars in the bulge likely originated from the tidal disruption of globular clusters

Ansiedad y personalidad como indicadores del rendimiento académico universitario en el aula de idiomas

The main purpose of this study is to test whether students’ performance in official language tests in the university context is influenced, apart from anxiety, by certain personality traits. A sample of 394 university students in Spain were assessed in language academic performance using the Test of English for International Communication: Listening and Reading (TOEIC L&R), Foreign Language Anxiety using the Spanish version of the Foreign Language Classroom Anxiety Scale (FLCAS), Test Anxiety, by means of the Spanish version of the Test Anxiety Inventory and Personality Traits through the Five Factor Inventory (NEO-FFI). Frequency analyses for the categorical variables, and means and standard deviations for continuous variables were calculated, and a forward stepwise regression model was used to assess the independent variables that contributed significantly to the variance in the score on the academic performance. Foreign Language Classroom Anxiety (FLCA) correlated most significantly with student foreign language academic performance, followed by the Neuroticism dimension, Test Anxiety and Extraversion. These results show that anxiety can still be considered the best indicator to predict language academic performance and that personality traits do play a relevant part in the foreign language learning process in the university context.El objetivo de este estudio es comprobar si, aparte de la ansiedad, ciertas dimensiones de la personalidad tienen influencia en el rendimiento académico universitario en exámenes oficiales de idiomas. En una muestra de 394 estudiantes de una universidad española, se evaluó el rendimiento académico en idiomas mediante el examen Test of English for International Communication: Listening and Reading (TOEIC L&R), la ansiedad en lengua extranjera con la FLCAS, la ansiedad ante los exámenes con el Test Anxiety Inventory y las dimensiones de la personalidad con el NEO-FFI. Se calcularon análisis de frecuencias para las variables categóricas, y medias y desviación estándar para las variables continuas, y se aplicó un modelo de regresión lineal múltiple por pasos para identificar las variables independientes que contribuyen de manera significativa a la varianza del resultado del rendimiento académico. La ansiedad en el aula de idiomas es la variable que correlaciona más significativamente con el rendimiento académico, seguida por la dimensión de Neuroticismo, la Ansiedad ante los Exámenes y Extraversión. Los resultados muestran que la ansiedad puede seguir siendo considerada el indicador más eficaz para predecir el rendimiento académico en idiomas y que las dimensiones de la personalidad tienen cabida en el proceso de aprendizaj

Control nutricional de las gestantes atendidas en el Centro Médico Universitario de la UNSM – T mediante un sistema de información nutricional bajo plataforma web

El presente estudio de investigación titulada “Control nutricional de las gestantes atendidas en el centro médico universitario de la UNMS – T mediante un sistema de información nutricional bajo plataforma web”, tiene como objetivo mejorar el control nutricional en gestantes a través de un sistema de información web que se implementó en el Centro Médico Universitario – Tarapoto. Esta tecnología de información brinda una solución factible y razonable a fin de permitir al Obstetra encargado del uso del sistema, dar un seguimiento y ayudar en la toma de decisiones con respecto a las dietas alimentarias de cada gestante. El Sistema de información se realizó empleando herramientas tecnológicas como modeladores, base de datos y leguaje de programación, posteriormente se llegó a implementar en el área de Obstetricia del Centro Médico, obteniendo así la población de gestantes, sus datos sobre su estado nutricional y registrando las tablas nutricionales. Estos datos fueron comparados en un antes y un después de los diferentes grupos para así poder determinar la mejora en una línea de tiempo de su estado nutricional de acuerdo a su tiempo de gestación. Se trabajó con 30 gestantes, las cuales estaban divididas en 2 grupos (grupo control y grupo experimental), con el resultado de la aplicación del sistema de información, se concluyó que el promedio entre ambos grupos era significativo por ende se mejoró en el proceso de control nutricional de las gestantes, el tiempo de atención se redujo en un 38,9% apoyando así a la toma de decisiones del Obstetra.The following research study titled as "Nutritional control of the procedures in the university medical center of the UNSM - T through a nutritional information system under a web platform", aims to improve nutritional control in pregnant women through a web information system that was implemented in the University Medical Center - Tarapoto.

Determinants of HDL Cholesterol Efflux Capacity after Virgin Olive Oil Ingestion: Interrelationships with Fluidity of HDL Monolayer

Scope: Cholesterol efflux capacity of HDL (CEC) is inversely associated with cardiovascular risk. HDL composition, fluidity, oxidation, and size are related with CEC. We aimed to assess which HDL parameters were CEC determinants after virgin olive oil (VOO) ingestion. Methods and results: Post‐hoc analyses from the VOHF study, a crossover intervention with three types of VOO. We assessed the relationship of 3‐week changes in HDL‐related variables after intervention periods with independence of the type of VOO. After univariate analyses, mixed linear models were fitted with variables related with CEC and fluidity. Fluidity and Apolipoprotein (Apo)A‐I content in HDL was directly associated, and HDL oxidative status inversely, with CEC. A reduction in free cholesterol, an increase in triglycerides in HDL, and a decrease in small HDL particle number or an increase in HDL mean size, were associated to HDL fluidity. Conclusions: HDL fluidity, ApoA‐I concentration, and oxidative status are major determinants for CEC after VOO. The impact on CEC of changes in free cholesterol and triglycerides in HDL, and those of small HDL or HDL mean size, could be mechanistically linked through HDL fluidity. Our work points out novel therapeutic targets to improve HDL functionality in humans through nutritional or pharmacological interventions.Fil: Fernández Castillejo, Sara.

Development of mucoadhesive sprayable gellan gum fluid gels

The nasal mucosa provides a potentially good route for local and systemic drug delivery. However, the protective feature of the nasal cavity make intranasal delivery challenging. The application of mucoadhesive polymers in nasal drug delivery systems enhances the retention of the dosage form in the nasal cavity. Several groups have investigated using low acyl gellan as a drug delivery vehicle but only limited research however, has been performed on high acyl gellan for this purpose, despite its properties being more conducive to mucoadhesion. High acyl gellan produces highly elastic gels below 60 °C which make it difficult to spray using a mechanical spray device. Therefore, in this study we have tried to address this problem by making fluid gels by introducing a shear force during gelation of the gellan polymer. These fluid gel systems contain gelled micro-particles suspended in a solution of un-gelled polymer. These systems can therefore behave as pourable viscoelastic fluids. In this study we have investigated the rheological behavior and mucoadhesion of fluid gels of two different types of gellan (high and low acyl) and fluid gels prepared from blends of high and low acyl gellan at a 50:50 ratio. The results demonstrated that by preparing fluid gels of high acyl gellan, the rheological properties were sufficient to spray through a standard nasal spray device. Moreover fluid gels also significantly enhance both high acyl and low acyl gellan mucoadhesion properties
