Some students of grade fourth were taken, which shawed some difficulties in reading comprehension and written production implemented an investigation called the narrative speech and its representation throught comics, a didactic proporsal to promote reading and writing in grade fourth in Gimnasio Santa Rocio aiming reinforcing reading comprehension from short narrative texts (fables and tales) those allowed to create comics. For its implementation some workshops and ludic activities were implemented; where students read text, identified characters, created and introduced their own comics to be included into the book ?My creations?. For this process it was taken into account the qualitative investigation and the participatory action research design. According to that, it is based in the rules issued by the government policies in general law of education (Ley general de Educaci?n), Curricular Guidelines (Lineamientos Curriculares) same as some theorist such as Amaya (2002), C?rdenas (2004), Baena (1996), Ni?o (1985), Vygotsky (1997), Piaget (1973) and Ausubel (1983) who strengthen the conceptualization of language, reading, writing, narrative text, comic, physiological and pedagogical aspects that were useful as a base for methodological development. In that order of ideas was achieved that students would develop the reading competence, the creations of own texts from experiences of everyday life involving comic as a didactic strategy that strength comprehension and textual production.

Molecular and biochemical mechanisms of acaricide resistance in common cattle tick Rhipicephalus microplus

P?ginas 72-81Recurso Electr?nicoLa garrapata com?n de los bovinos, Rhipicephalus (Boophilus) microplus, considerada uno de los problemas parasitarios m?s importantes en ?reas tropicales y subtropicales del mundo, desde hace algunas d?cadas ha venido desarrollando resistencia a los acaricidas que se emplean para su control, que se han vuelto ineficaces. La resistencia, que es de car?cter gen?tico, preadaptativo, originada en mutaciones del ADN, requiere el estudio de los genes relacionados con su manifestaci?n y que en R. microplus generan, principalmente, dos tipos de respuesta fisiol?gica, como el aumento en la detoxificaci?n enzim?tica y la insensibilidad en el sitio blanco. Esta revisi?n busca describir los mecanismos de acci?n de los acaricidas empleados com?nmente para controlar esta garrapata y las alteraciones gen?ticas y moleculares que interfieren en la acci?n de estos compuestos qu?micos, cuya identificaci?n posibilitar?a el ajuste de los planes de control a fin de reducir el grado de selecci?n hacia los mecanismos de resistencia.ABSTRACT. The common cattle tick, Rhipicephalus (Boophilus) microplus, considered one of the most important parasitic problems in tropical and subtropical areas of the world, for the last few decades has developed resistance to acaricides used for control, rendering them ineffective. The resistance, which is genetic in nature, preadaptative and originated from DNA mutations, requires the study of the genes that are related with their manifestation in R. microplus, where it generates mainly two types of physiological response such as an, increased enzymatic detoxification and insensitivity at the target site. This review aims to describ the mechanisms of action of acaricides commonly employed to control this ticks and finally the genetic and molecular alterations that interfere with the action of these chemicals and whose identification allows to adjust control programs to reduce the degree of acaricide resistance

Similar plasma lipidomic profile in people living with HIV treated with a darunavir-based or an integrase inhibitor-based antiretroviral therapy

Cardiovascular disease is an important cause of morbidity and mortality in people living with HIV (PLWH), who commonly experience lipid disturbances. The aim of this study was to determine whether the plasma lipidomic profile differs between PLWH receiving a darunavir-based ART and those receiving integrase inhibitor-based ART. This was a cross-sectional study of unselected patients for whom metabolomic analysis was performed using ultra-high-performance liquid chromatography coupled to mass spectrometry. Data for the two subgroups were compared by calculating the log2 of the fold change for each metabolite and then grouping these into the main lipid families. Sixty-two PLWH aged 49.3 +/- 8.6 years (82% men) were included: 12 patients (19.4%) had hypertension, 8 (12.9%) had type 2 diabetes, 25 (41.0%) had dyslipidaemia and 9 (14.5%) were taking statins, without significant differences in all these variables between the two groups. Twenty-five (40.3%) received darunavir-based ART and 37 (59.7%) integrase inhibitor-based ART. Although the differences were not statistically significant, patients treated with darunavir-based ART had higher concentrations of total cholesterol (211 mg/dL vs 194 mg/dL), LDL-cholesterol (132 mg/dL vs 117 mg/dL) and triglycerides (155 mg/dL vs 122 mg/dL), and lower HDL-cholesterol concentration (50 mg/dL vs 52 mg/dL). The main lipid families and metabolites differed slightly between groups (log2-fold change; P-value): ceramides (-0.07; 0.49), phosphatidylinositols (-0.05; 0.63), diacylglycerols (0.10; 0.64), phosphatidylethanolamines (0.03; 0.78), triacylglycerols (0.27; 0.18) and lysophosphatidylethanolamines (0.03; 0.83). In the integrase inhibitor-based group, the use of tenofovir alafenamide fumarate significantly increases the majority of lipid fractions, when compared with tenofovir disoproxil fumarate. The lipidomic profile did not differ between PLWH treated with darunavir-based or integrase inhibitor-based ART. This was especially true for ceramides, which are involved in cardiovascular disease. Further studies are needed to study the impact of ART in lipidomic profile

Rindler Particles and Classical Radiation

We describe the quantum and classical radiation by a uniformly accelerating point source in terms of the elementary processes of absorption and emission of Rindler scalar photons of the Fulling-Davies-Unruh bath observed by a co-accelerating observer.To this end we compute the emission rate by a DeWitt detector of a Minkowski scalar particle with defined transverse momentum per unit of proper time of the source and we show that it corresponds to the induced absorption or spontaneous and induced emission of Rindler photons from the thermal bath. We then take what could be called the inert limit of the DeWitt detector by considering the limit of zero gap energy. As suggested by DeWitt, we identify in this limit the detector with a classical point source and verify the consistency of our computation with the classical result. Finally, we study the behavior of the emission rate in D space-time dimensions in connection with the so called apparent statistics inversion.Comment: 8 pages, 2 figure

Transtibial amputee gait efficiency : energy storage and return versus solid ankle cushioned heel prosthetic feet

Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait. However, despite being prescribed for approximately thirty years, there is limited evidence that they achieve this desired function. Here, we report a meta-analysis of data from ten studies which met our selection criteria to determine whether amputee walking with ESR feet is more efficient than with conventional solid ankle cushioned heel (SACH) feet. Additionally, the data were tested for a relationship with walking speed; since it has been suggested ESR feet might perform better at higher speeds. The raw data are highly variable due to differences in study protocols; therefore we normalised the data and found a statistically significant difference (p < 0.001) between ESR and SACH feet. However, the magnitude of this difference is small, with the cost of transport (COT) with ESR feet being 97.3% of the cost with SACH feet. No relationship between ESR COT and speed was found (p = 0.191). In the authors’ opinion, these results suggest that ESR feet are not effective at improving amputee COT to a clinically relevant degree. We hypothesise this is due to limited push-off at the end of stance compared with able-bodied ankles

Principales dispositivos tecnol?gicos que intervienen en el proceso de aprendizaje en los alumnos de grado d?cimo de la instituci?n educativa San Bernardo del municipio de Ibagu?

40 p. Recurso Electr?nicoEn este art?culo se presentan los resultados de una investigaci?n adelantada con estudiantes de d?cimo grado de la Instituci?n Educativa San Bernardo ubicada en la zona rural del municipio de Ibagu?. El objetivo era determinar si los dispositivos tecnol?gicos usados por alguno(as) estudiantes incid?an en su proceso de aprendizaje. El enfoque metodol?gico que se utiliz? fue de car?cter mixto; Desde una perspectiva cualitativa, se recurri? a la entrevista semiestructurada, observaciones a la poblaci?n seleccionada, y desde la cuantitativa, a la encuesta de tipo abierta; el muestreo es probabil?stico no intencional, con 20 estudiantes entre los 15 y 18 a?os. Tambi?n, participaron algunos docentes que orientan diferentes ?reas en este grado. En los resultados encontrados se evidencia que en la poblaci?n seleccionada la mayor?a de los estudiantes hacen uso de los dispositivos tecnol?gicos en horas de clase; Adem?s, el manejo que le hacen a estos equipos es de forma inapropiada en (Redes sociales, juegos, chat y llamadas) causando distracci?n en sus actividades acad?micas. La investigaci?n permiti? concluir que son m?ltiples los factores que inducen a los estudiantes a utilizar tales dispositivos en el aula de clase; entre ellos, el poco inter?s de los estudiante por los aprendizajes te?ricos, la escasa motivaci?n por parte del docente al momento de desarrollar sus clases dado que privilegia las clases magistrales, por su parte, los docentes expresan el precario inter?s de los estudiante por formarse acad?micamente.In this article shows the results of an advanced research with 10 grade high school from San Bernardo educational institution of Ibagu? (Instituci?n eductiva San Bernardo del municipio de Ibagu?). The main goal was to determine if technological devices used for some students would influence in their learning process. The methodological focus that was used is about mixed character; from a qualitative perspective, it is used to half-estructured interview, observations to the target population from this research, and since the cuantitative character one, to the open type survey; the sampling is probabilistic sampling is unintentional, with a population of 20 students between 15 and 18 years old. In other hand, some teachers have been population participant who lead different subjects in that grade of high school. In the found results it may show that in the chosen populace the majority of students make use of technological devices in time class; In addition, the usages which make to those devices is in an inappropriate way in social media, games, chat and calls causing distraction in their academic activities.
