On-Offer and Residual Forage in a Massai-\u3cem\u3eLeucaena\u3c/em\u3e Pasture at Different Leucaena Density

Mexican livestock producers in tropical areas are increasingly interested on the establishment of silvopastoral systems based on Leucaena (Leucaena leucocephala (Lam.) de Wit) and different tropical grasses as the Massai grass (Panicum maximum cv Massai); among questions raised on this is the importance of Leucaena density in relation to forage available. Then the objective of the study was to determine total and by species on-offer and residual forage in a grazed MassaiLeucaena pasture with different Leucaena density

Differential expression of circulating miRNAs as a novel tool to assess BAG3-associated familial dilated cardiomyopathy.

A new familial dilated cardiomyopathy (FDCM) was found related to mutations in BAG3 gene. MicroRNAs (miRNAs) represent new targets of FDCM, although no studies have assessed clinical association between Bcl2-associated athanogene 3 (BAG3)-related DCM and miRNAs. Here, we studied whether a clinical association between BAG3-related FDCM and circulating miRNAs may have diagnostic and prognostic value in a small cohort of familial related individuals carrying a BAG3 mutation (BAG3+) and/or diagnosed of dilated cardiomyopathy (DCM) (DCM+). The analysis of 1759 circulating miRNAs showed significant differences between BAG3+ and BAG3- individuals for miRNAs mir-3191-3p, 6769b-3p, 1249-ep, 154-5p, 6855-5p, and 182-5p, while comparisons between BAG3+/DCM+ versus BAG3+/DCM- were restricted to miRNAs mir-154-5p, 6885-5p, and 182-5p, showing significant correlation with systolic and diastolic blood pressure, A wave, left atrium length, and left atrium area. Additionally, when stratified by gender and age, miRNAs were statistically correlated with critical parameters, including left ventricle ejection fraction (LVEF) and ventricular diameter, in women and young men. Likewise, 56% of BAG3+/DCM+, significantly co-expressed mir-154-5p and mir-182-5p, and a slight 4% did not express such combination, suggesting that co-expression of mir-154-5p and mir-182-5p may potentially show diagnostic value. Further studies will require long-term follow-up, and validation in larger populations.post-print729 K

Winter Forage Yield of Signal Grass (\u3cem\u3eBrachiaria brizantha \u3c/em\u3e(Hochst. Ex. A. Rich) R.D. Webster) at Different Cutting Frequency and N Fertilization

Signal grass (Brachiaria brizantha (Hochst. Ex. A. Rich) R.D. Webster) is widely grown in sub-humid tropical environments. In winter, shorter photoperiod and lower rainfall and temperatures reduce grass forage yield. Cutting frequency and N fertilization might reduce this negative effect (Whitehead, 1995; Pereira et al., 2014). The objective of the study was to determine winter forage yield total and by components of Signal grass under different cutting frequency and N fertilization

Un estudio de la literatura de Facebook en el ámbito académico

A la vista de los resultados contradictorios sobre los efectos positivos o negativos que puede tener el uso de Facebook en el ámbito académico, el objetivo de este trabajo es analizar la literatura sobre Facebook para conocer las conclusiones de los trabajos acerca de su influencia en dichos resultados. A través de la revisión de 37 artículos sobre esta temática podemos conocer qué revistas publican más sobre las repercusiones de Facebook en los resultados académicos, cuáles son los métodos de recogida de datos más utilizados, qué tópicos emergen paralelos al uso de Facebook en el ámbito académico, y qué países son más prolíficos en el tema. Las conclusiones apuntan que a pesar de la divergencia de resultados el balance es positivo acerca del uso de Facebook en el ámbito académico; en definitiva, hay más conclusiones a favor que en contra de esta tecnología. Esperamos que este trabajo sea una base para conocer más las posibilidades de Facebook en el ámbito académico

Uso de Facebook como completo docente

Las redes sociales son comunidades de personas que comparten algún tipo de interés. Las redes sociales online permiten a los individuos construir un perfil público o semi-público en un sistema delimitado, articular una lista de usuarios con los que se tiene conexión y ver y cruzar su lista de conexiones con otras hechas por distintos individuos del sistema. El uso de las redes sociales online ha crecido vertiginosamente en los últimos años, y los jóvenes son los principales protagonistas de esta tendencia. Inmersos y educados y criados en medio de la tecnología, la nueva generación de estudiantes son nativos digitales. Los profesores, en cambio, somos inmigrantes digitales, pero tenemos la responsabilidad de convertir una tecnología que puede ser una distracción en una herramienta de enseñanza. El objetivo del presente trabajo es mostrar nuestra experiencia docente, en las asignaturas de grado de Dirección de Recursos Humanos, en la Universidad de Alicante, con la red social Facebook, obteniendo conclusiones y recomendaciones para mejorar el uso de redes sociales en la enseñanza universitaria

Effect of Grazing Management on Herbage Accumulation of Lucerne-Orchard Grass Sward

Throughout most of México, lucerne (Medicago sativa) is the primary forage legume used in the dairy industry. Unfortunately, lucerne does not grow in late autumn and winter due to adverse weather. Recent studies with lucerne have suggested that the inclusion of a companion grass will invariably increase the seasonal distribution and total annual yield of swards (Laidlaw & Teuber, 2001). However the management of mixed swards containing lucerne is difficult as a grazing frequency or intensity which suits one species may be detrimental to the other. Changes in balance between grass and legume, especially in grazed swards, have been observed. In México mixtures of lucerne-orchard grass have a good persistence and productivity. However the explanation for this is unclear. This study examined the effects of different grazing management practices on lucerne-orchard grass production and seasonal distribution

Uso de Redes Sociales en asignaturas de Grado de Dirección de Recursos Humanos

El uso de las redes sociales online ha crecido vertiginosamente en los últimos años, y los jóvenes son los principales protagonistas de esta tendencia. Inmersos y educados y criados en medio de la tecnología, la nueva generación de estudiantes son nativos digitales. Los profesores, en cambio, somos inmigrantes digitales, pero tenemos la responsabilidad de convertir una tecnología que puede ser una distracción en una herramienta de enseñanza. Facebook es un ejemplo de tecnología Web 2.0 que tiene un enorme potencial en el campo de la educación, aunque no fue creada para construir o manejar experiencias de aprendizaje. Opera en una plataforma abierta, a diferencia de otros sistemas organizados alrededor de cursos estructurados formalmente. De hecho, aunque Facebook no es un entorno de aprendizaje, puede servir como un soporte muy valioso para las nuevas orientaciones sociales que aparecen ahora en los procesos educativos. El objetivo del presente trabajo es mostrar nuestra experiencia docente, en las asignaturas de grado de Dirección de Recursos Humanos, en la Universidad de Alicante, con la red social Facebook, obteniendo conclusiones y recomendaciones para mejorar el uso de redes sociales en la enseñanza universitaria

Clinical factors associated with a Candida albicans Germ Tube Antibody positive test in Intensive Care Unit patients

Background: Poor outcomes of invasive candidiasis (IC) are associated with the difficulty in establishing the microbiological diagnosis at an early stage. New scores and laboratory tests have been developed in order to make an early therapeutic intervention in an attempt to reduce the high mortality associated with invasive fungal infections. Candida albicans IFA IgG has been recently commercialized for germ tube antibody detection (CAGTA). This test provides a rapid and simple diagnosis of IC (84.4% sensitivity and 94.7% specificity). The aim of this study is to identify the patients who could be benefited by the use of CAGTA test in critical care setting. Methods: A prospective, cohort, observational multicentre study was carried out in six medical/surgical Intensive care units (ICU) of tertiary-care Spanish hospitals. Candida albicans Germ Tube Antibody test was performed twice a week if predetermined risk factors were present, and serologically demonstrated candidiasis was considered if the testing serum dilution was >= 1: 160 in at least one sample and no other microbiological evidence of invasive candidiasis was found. Results: Fifty-three critically ill non-neutropenic patients (37.7% post surgery) were included. Twenty-two patients (41.5%) had CAGTA-positive results, none of them with positive blood culture for Candida. Neither corrected colonization index nor antifungal treatment had influence on CAGTA results. This finding could corroborate that the CAGTA may be an important biomarker to distinguish between colonization and infection in these patients. The presence of acute renal failure at the beginning of the study was more frequent in CAGTA-negative patients. Previous surgery was statistically more frequent in CAGTA-positive patients. Conclusions: This study identified previous surgery as the principal clinical factor associated with CAGTA-positive results and emphasises the utility of this promising technique, which was not influenced by high Candida colonization or antifungal treatment. Our results suggest that detection of CAGTA may be important for the diagnosis of invasive candidiasis in surgical patients admitted in ICU.This study has been supported by a Pfizer research gran
