Influence of a Concurrent Exercise Training Intervention during Pregnancy on Maternal and Arterial and Venous Cord Serum Cytokines: The GESTAFIT Project

The aim of the present study was to analyze the influence of a supervised concurrent exercise-training program, from the 17th gestational week until delivery, on cytokines in maternal (at 17th and 35th gestational week, and at delivery) and arterial and venous cord serum. Fifty-eight Caucasian pregnant women (age: 33.5 +/- 4.7 years old, body mass index: 23.6 +/- 4.1kg/m(2)) from the GESTAFIT Project (exercise (n = 37) and control (n = 21) groups) participated in this quasi-experimental study (per-protocol basis). The exercise group followed a 60-min 3 days/week concurrent (aerobic-resistance) exercise-training from the 17th gestational week to delivery. Maternal and arterial and venous cord serum cytokines (fractalkine, interleukin (IL)-1 beta, IL-6, IL-8, IL-10, interferon (IFN)-gamma, and tumor necrosis factor (TNF)-alpha) were assessed using Luminex xMAP technology. In maternal serum (after adjusting for the baseline values of cytokines), the exercise group decreased TNF-alpha (from baseline to 35th week, p = 0.02), and increased less IL-1 beta (from baseline to delivery, p = 0.03) concentrations than controls. When adjusting for other potential confounders, these differences became non-significant. In cord blood, the exercise group showed reduced arterial IL-6 and venous TNF-alpha (p = 0.03 and p = 0.001, respectively) and higher concentrations of arterial IL-1 beta (p = 0.03) compared to controls. The application of concurrent exercise-training programs could be a strategy to modulate immune responses in pregnant women and their fetuses. However, future research is needed to better understand the origin and clearance of these cytokines, their role in the maternal-placental-fetus crosstalk, and the influence of exercise interventions on them

Dicotomías entre el ser y la entidad : reflexiones en clave critica para el Ser franciscano en la Licenciatura en Educación Física y Deportes de la Universidad de San Buenaventura Medellín

This research what you want is to analyze if the speeches used by teachers of the Faculty of education in the area of physical education correspond to the critical and reflective discourse posed by the University of San Buenaventura Medellín from his Franciscan education. Therefore, known since its inception, the Franciscan pedagogy used as autonomous principle at the University of San Buenaventura, which seeks that, the discourse of teachers Master's degree in physical education and sports, is consistent and is linked to the issues raised by this pedagogy, and apart from that practice and theory also work together as a strategy to be used in the training process. Likewise, also performed a trace of research and books related to "Being", based on an author such as Martin Heidegger in order to understand and measure this category to bring up the speeches of teachers and show how is located or which permeates at the University of San Buenaventura in terms of training in the Faculty of education. In this order, are looking for ways to relate to being with pedagogy institutional University of San Buenaventura Medellín, therefore this work arise 3 categories which are: being and the entity, being in education and being in physical educationEsta investigación lo que quiere es analizar si los discursos utilizados por los docentes de la facultad de Educación en el área de Educación Física corresponden al discurso crítico y reflexivo que plantea la Universidad de San Buenaventura Medellín desde su pedagogía franciscana. Por lo tanto, se conoce desde sus inicios, la pedagogía franciscana utilizada como principio autónomo en la Universidad de San Buenaventura, la cual busca que el discurso de los docentes de la licenciatura en educación física y deportes, sea coherente y esté ligado a lo planteado por dicha pedagogía, y aparte de eso que la práctica y la teoría también trabajen conjuntamente como estrategia para utilizar en el proceso de formación. Así mismo, También se realiza un rastreo de investigaciones y libros relacionados con el “Ser”, basándonos en un autor como es Martin Heidegger con el fin de entender y dimensionar esta categoría para traer a colación los discursos de docentes y demostrar cómo se encuentra o que permea en la Universidad de San Buenaventura en cuanto a la formación en la facultad de educación. En este orden, se busca la forma de relacionar el ser con la pedagogía institucional de la Universidad de San Buenaventura Medellín, por lo tanto, de este trabajo surgen 3 categorías las cuales son: Ser y la Entidad, Ser en la Educación y Ser en la Educación Físic

A General Solution for Troesch's Problem

The homotopy perturbation method (HPM) is employed to obtain an approximate solution for the nonlinear differential equation which describes Troesch’s problem. In contrast to other reported solutions obtained by using variational iteration method, decomposition method approximation, homotopy analysis method, Laplace transform decomposition method, and HPM method, the proposed solution shows the highest degree of accuracy in the results for a remarkable wide range of values of Troesch’s parameter

The Characteristics of the HIV-1 Env Glycoprotein Are Linked With Viral Pathogenesis

The understanding of HIV-1 pathogenesis and clinical progression is incomplete due to the variable contribution of host, immune, and viral factors. The involvement of viral factors has been investigated in extreme clinical phenotypes from rapid progressors to long-term non-progressors (LTNPs). Among HIV-1 proteins, the envelope glycoprotein complex (Env) has been concentrated on in many studies for its important role in the immune response and in the first steps of viral replication. In this study, we analyzed the contribution of 41 Envs from 24 patients with different clinical progression rates and viral loads (VLs), LTNP-Elite Controllers (LTNP-ECs); Viremic LTNPs (vLTNPs), and non-controller individuals contemporary to LTNPs or recent, named Old and Modern progressors. We studied the Env expression, the fusion and cell-to-cell transfer capacities, as well as viral infectivity. The sequence and phylogenetic analysis of Envs were also performed. In every functional characteristic, the Envs from subjects with viral control (LTNP-ECs and vLTNPs) showed significant lower performance compared to those from the progressor individuals (Old and Modern). Regarding sequence analysis, the variable loops of the gp120 subunit of the Env (i.e., V2, V4, and mainly V5) of the progressor individuals showed longer and more glycosylated sequences than controller subjects. Therefore, HIV-1 Envs from virus of patients presenting viremic control and the non-progressor clinical phenotype showed poor viral functions and shorter sequences, whereas functional Envs were associated with virus of patients lacking virological control and with progressor clinical phenotypes. These correlations support the role of Env genotypic and phenotypic characteristics in the in vivo HIV-1 infection and pathogenesis.This work is supported by Spanish AIDS network “Red Temática Cooperativa de Investigación en SIDA” RD12/0017/0002, RD12/0017/0028, RD12/0017/0034, RD16/0025/0011, RDCIII16/0002/0005, and RD16/0025/0041 as part of the Plan Nacional R + D + I and cofunded by Spanish “Instituto de Salud Carlos III (ISCIII)-Subdirección General de Evaluación y el Fondo Europeo de Desarrollo Regional (FEDER).” JB is a researcher from “Fundació Institut de Recerca en Ciències de la Salut Germans Trias i Pujol” supported by the Health Department of the Catalan Government/Generalitat de Catalunya and ISCIII grant numbers PI17/01318 and PI20/00093 (to JB).

Key epidemiological indicators and spatial autocorrelation patterns across five waves of COVID-19 in Catalonia

This research studies the evolution of COVID-19 crude incident rates, effective reproduction number R(t) and their relationship with incidence spatial autocorrelation patterns in the 19 months following the disease outbreak in Catalonia (Spain). A cross-sectional ecological panel design based on n = 371 health-care geographical units is used. Five general outbreaks are described, systematically preceded by generalized values of R(t) > 1 in the two previous weeks. No clear regularities concerning possible initial focus appear when comparing waves. As for autocorrelation, we identify a wave’s baseline pattern in which global Moran’s I increases rapidly in the first weeks of the outbreak to descend later. However, some waves significantly depart from the baseline. In the simulations, both baseline pattern and departures can be reproduced when measures aimed at reducing mobility and virus transmissibility are introduced. Spatial autocorrelation is inherently contingent on the outbreak phase and is also substantially modified by external interventions affecting human behavior

Geología y geodinámica de la quebrada Chicón: el aluvión del 17 de octubre del 2010 que afectó Urubamba-Cusco

En la quebrada Chicón del distrito de Urubamba, en la Región Cusco, el día domingo 17 de octubre del 2010 ocurrió un aluvión, producto del desprendimiento de una pequeña masa de hielo (100 x 30 m) del borde meridional del glaciar el Chicón, que afectó parte de la ciudad de Urubamba, a unas 300 viviendas, inundó tierras de cultivo y hubo más de 1,200 damnificados. La planicie de Occororuyoc, en realidad una depresión natural, permitió la sedimentación de la mayor parte del aluvión, y solo una parte menor, llegó a la ciudad. A pesar de existir esta depresión natural, se propone realizar los monitoreos respectivos del nevado y los trabajos de preparación con la población
