Analgesia epidural durante el trabajo de parto en primigestas atendidas en sala de labor y parto del Hospital Militar Escuela Dr. Alejandro Dávila Bolaños Managua Marzo a Noviembre 2019
Con el Objetivo de describir el comportamiento de la analgesia epidural en las primigestas atendidas en sala de labor y parto del Hospital Militar Escuela Alejandro Dávila Bolaños en el periodo comprendido de marzo a noviembre 2019. MetodologÃa: Se realizó un estudio de tipo Descriptivo, Prospectivo de corte transversal y por conveniencia tomando como población las pacientes primigestas que ingresan a la sala de labor y parto y asà mismo que cumplieran con los criterios de inclusión, se les administro analgesia epidural a 31 pacientes valorando caracterÃsticas generales de las embarazadas, cambios hemodinámicos, efectos colaterales en el trabajo de parto, escala del dolor EVA y el estado de vigor del recién nacimiento a través del puntaje de APGAR.
Resultados: La diferencia de las medias de la frecuencia cardiaca entre el inicio y los 15 minutos de aplicado el bloqueo epidural que fueron 80.5 y 71.1latidos por minuto, también demostró que la distribución de los datos según prueba de Shapiro Wilk eran desiguales es decir <0.05 pero la prueba de t de Studen demuestra significancia estadÃstica es decir pt=0.000 menor que a=0.05. La comparación del EVA inicial y posterior a los 15 minutos de aplicado el bloqueo se encontró de 6.6 y 2.5 respetivamente, según la prueba de Shapiro Wilk la distribución de los datos eran desiguales siendo de 0.00 y 0.0001 pero la significancia según prueba de t de Studen era 0.000. Los dos valores identificados de APGAR fue de 8 y 9 como estado de vigor del neonato.
Conclusión: Los cambios en los niveles de EVA, dependiente a la aplicación del bloqueo epidural con bupivacaina como analgesia hacia la ausencia de dolor y la presencia de cambios mÃnimos de efectos hemodinámico como efectos colaterales para la madre y el recién nacido, quedo demostrado el beneficio ampliament
Emerging issues in COVID-19 vaccination in Tropical Areas: Impact of the Immune Response against Helminths in Endemic Areas
The Coronavirus Disease 2019 (COVID-19) pandemic has affected over 165 million people and caused the death of 3.4 million worldwide (up to May 20, 2021) (https://coronavirus.jhu.edu/map.html), becoming a serious problem of global public health and the worst epidemic in the last century, after the pandemic 1918 influenza. Researchers worldwide are trying to find valuable drugs against the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). Some of them focused as antivirals, others targeted in other ways (e.g. immunomodulation) to relieve the symptoms of the infected patients and help lower the death toll throughout the world. Unfortunately, there is a lack of effective drugs to manage COVID-19
Development of a simulation procedure for the evaluation of new refractories for aluminium furnaces
Refractory materials for aluminium industry are designed to be resistant to different degrees of thermal, mechanical and chemical wear. The refractory wall thickness reduction during service life increases the heat losses through walls decreasing the thermal efficiency of the furnace. Last developments are focused on obtaining refractories with better performance and improved insulation properties.
On this regard, a simulation procedure has been developed to compare the thermal and chemical performance of different refractories during end use. This procedure includes measuring the internal and external wall temperatures of a testing furnace using thermography, and comparing the resistance to liquid aluminium determining the corundum and cracks appearance. Two refractories have been tested by this procedure for comparative purposes; a commercial alumina castable and an improved alumina castable with better insulation properties.European Commission's Seventh Framework Programme for Research (FP7
A novel procedure for the evaluation of new refractories for aluminium furnaces

Last developments are focused on obtaining refractories with better performance and improved insulation properties.
On this regard, a novel procedure has been developed to compare the thermal and chemical performance of different refractories. This procedure includes comparing the resistance of the refractory to molten aluminium, determining corundum and cracks appearance, and measuring the internal and external wall temperatures of a testing furnace using thermography. These temperature measurements make possible to estimate the wall thermal conductivity together with its evolution in time and also validate its simulation modelling in order to be used in future furnace designs. Two refractories have been tested by this procedure for comparative purposes; a commercial alumina castable and an improved alumina castable with better insulation propertiesEuropean Commission - Seventh Framework Programme for Research (FP7)
Cholinoceptor Activation Subserving the Effects of Interferon Gamma on the Contractility of Rat Ileum
Recombinant rat interferon γ stimulated the contractility of
isolated rat ileum at doses of 4–12 units/ml. Muscarinic
cholinoceptors were involved, as treatment of the tissue with
atropine prevented the contractile response of the ileum.
Furthermore, interferon γ increased the affinity of carbachol for
the cholinoceptors and did not change its maximum effect. Neurogenic
pathways were also involved since pretreatment of ileum with
hexamethonium, hemicholinium or tetrodotoxin impaired the
contractile effect of interferon γ. In contrast to the action of
exogenous carbachol, the effects of interferon γ are indirect. They
appear to involve a G protein regulating phosphoinositide turnover
and cytoskeletal structures since they could not be induced in ileum
strips that were pretreated with pertussis toxin, phospholipase C
inhibitors (2-nitro-carboxyphenyl, NN-diphenyl carbamate and
neomycin), cytochalasine B or colchicine
University, Territory and Players’ Framework: The Case of UNPAZ
La Universidad Nacional de José C. Paz (UNPAZ) fue creada en el año 2009 mediante la Ley 26.577 con el objetivo de promover el acceso a la educación superior a un amplio sector de la población. Uno de los ejes centrales de la propuesta universitaria, en sintonÃa con el espÃritu de las Universidades del Bicentenario, es la articulación con el territorio (Andrade et al., 2018) mediante la formulación de un proyecto educativo inclusivo y democrático en concordancia con los intereses de la realidad paceña (Roca, et al., 2018). Esto supone reconocer las problemáticas sociales como también las organizaciones y el marco actoral que tiene incidencia local en la comunidad de José C. Paz.El objetivo de este trabajo es abordar en clave territorial el entramado actoral relacional que se construye a partir de la instalación de la universidad, pudiendo dar cuenta de las articulaciones que se tejen junto con las organizaciones y actores (económicos, sociales, gremiales, religiosos, estatales) con presencia local. A través del análisis de la perspectiva de los actores locales entrevistados, se estudian las caracterÃsticas de estas organizaciones, la vinculación con la comunidad y con la UNPAZ. Partimos de la idea de que la UNPAZ, en su inscripción locacional contribuye a la reconfiguración de una territorialidad con particularidades en José C. Paz, debido a su rol como institución universitaria que se expresa en la construcción de alianzas y redes con actores diversos en articulación con las dinámicas y problemáticas del entorno social y urbano (López y MartÃnez, 2009).The National University of José C. Paz (UNPAZ) was created by law in 2009 in José C. Paz, a town in Buenos Aires province, with the aim of promoting access to higher education for a broad sector of the population. One of the axes of the university proposal has been the articulation with the territory, taking into account social problems and the players’ environment with local incidence, in order to promote an inclusive university project in accordance with the interests of La Paz reality. The aim of the work is to address from a territorial perspective the relational network among actors that is built as from the installation of the university, taking into account the network of organizations and actors (economic, social, trade union, religious, state) with a local presence. For that purpose, the characteristics of these organizations, the link with José C. Paz and with UNPAZ are studied, taking into account the perceptions and perspectives of the interviewed actors. We start from the idea that UNPAZ, in its strategic location, contributes to the reconfiguration of a territoriality with particularities in José C. Paz, due to its role as a university institution, in articulation with the dynamics and problems of the social and urban environment. This article is based on a qualitative methodological strategy, through semi-structured interviews with various actors and leading players among neighborhood organizations and institutions with an impact on José C. Paz.Fil: Rodriguez, Maria Florencia. Universidad de Buenos Aires. Facultad de Ciencias Sociales. Instituto de Investigaciones "Gino Germani"; Argentina.
