Introducción: Si bien la anastomosis intracorpórea (AI) ha demostrado ha demostrado beneficios clínicos sobre la anastomosis extracorpórea (AE) en la hemicolectomía derecha laparoscópica (HDL), su aplicación ha sido limitada por su dificultad técnica y curva de aprendizaje mas larga. El presente estudio busca desarrollar y evaluar un modelo simulado para entrenar este procedimiento. Material y método: Se desarrolló un modelo en base a tejido ex vivo, con colon porcino e intestino bovino, montados en un simulador de laparoscopía. Este se modificó sucesivamente en base a entrevistas semi-estructuradas a cirujanos hasta lograr el modelo final. Para evaluar apariencia y reacción al modelo, coloproctólogos, cirujanos y residentes previamente expuestos a entrenamiento simulado, realizaron una ileotransverso anastomosis mecánica en el modelo y luego contestaron una encuesta. Resultados: Doce sujetos participaron. Cuatro coloproctólogos, 4 residentes de coloproctología, 2 residentes de cirugía general, 1 cirujano general y 1 cirujano digestivo. El 91,6% valoró positivamente la ergonomía lograda, mientras que el 83,3% y 75% valoraron positivamente el uso del instrumental y la relación anatómica entre estructuras, respectivamente. Todos los participantes consideraron el modelo útil para entrenar sutura manual laparoscópica, el 91,6% para entrenar enterotomías y 83,3% para entrenar el uso de endograpadora. Todos declararon que el módulo permite entender y reflexionar sobre la técnica propuesta. Conclusión: Este modelo desarrollado sería útil para entrenar habilidades críticas para realizar una AI en HDL. Su incorporación a un programa de entrenamiento en laparoscopía avanzada podría contribuir a acortar la curva de aprendizaje de este procedimiento.

Published: April 2020

Introducción: Los tumores neuroendocrinos (TNE), son tumores compuestos por células productoras de péptidos y aminas. Los TNE gástricos, representan el 1% de todas las neoplasias, sin embargo su incidencia ha ido en aumento. Son generalmente asintomáticos y no funcionantes. El tratamiento es generalmente la resección local.Caso Clínico: paciente de 48 años con sospecha de cáncer gástrico; su estudio demuestra un TNE gástrico bien diferenciado tipo 1. Se realiza etapificación y se define en comité oncológico la vigilancia endoscópica. El hallazgo de un TNE, en el estudio de cáncer gástrico, es un hallazgo poco frecuente. Debido al aumento progresivo en la realización de endoscopías digestivas altas, secundario a la alta prevalencia de cáncer gástrico en nuestro país, se espera que aumenten hallazgos como un TNE. Es por esto que realizamos una revisión de la literatura y planteamos algunas conclusiones al respecto.

INDÍCIOS DE UMA DISPERSÃO

Published: April 2020

Mário de Sá-Carneiro foi um poeta expoente do modernismo português cuja obra tem a identidade como um dos temas mais recorrentes. Nesse estudo iremos investigar como a noção de identidade é representada de forma desintegrada na obra do autor, a partir da análise de três poemas: “Ângulo”, “7” e “Escavação”. Os poemas foram analisados individual e comparativamente, levando em conta os planos temático, sonoro, estrutural, semântico e sintático. Entendemos que os três poemas dialogam intimamente entre si em todos esses planos analíticos quando tomamos por base a temática da desintegração da identidade e ruína de si mesmo. Entendemos, ainda, que a ideia de desintegração identitária está acompanhada de uma sensação de não-pertencimento, tanto em relação ao mundo quanto em relação a si mesmo: por vezes o eu-lírico não se vê nele mesmo e nem em um outro.

Published: April 2020

The study investigated how the new four year Bachelor of Education degree students performed in their first ever quizzes organised by the University of Cape Coast (UCC). The student teachers were quizzed on some concepts in General Biology (EBS 103), a general course for all the forty-six (46) Colleges of Education in Ghana except students offering General Science as elective subject in the Colleges. The study involved the whole level hundred (L100) students of Abetifi Presbyterian College of Education who were selected through purposive and convenience sampling technique, totalling 435 students (195 female and 240 male). The test items used for the quizzes (Quiz 1 and 2) were constructed by Senior Lecturers of UCC with it reliability of 0.7 and its content and construct validity determined. Data was collected from the scores in both quizzes and were analysed using both descriptive and inferential statistics. An independent sample t-test conducted showed that there was a significant difference between the performance of the male student teachers and the female student teachers in both quizzes ( p = 0.000, p>0.05). The findings further revealed that there was a higher mean score in the quiz one compared to quiz 2; however, the mean difference was statistically insignificant (P=0.623, p>0.05).

Published: April 2020

Homeovox, a multicomponent homeopathic treatment for laryngitis of various etiologies, was tested for allergenic properties and immunotoxicity.Methods. 80 male albino guinea pigs and 180 male СВА, C57BL/6 and F1 hybrid (CBAхС57BL/6) mice were used in the study. In order to assess immunotoxicity, Homeovox was administrated orally to mice for 14 days at doses of 100 mg/kg and 1 000 mg/kg. To assess the allergenic properties of Homeovox, albino guinea pigs were also given the drug at doses of 100 mg/kg and 1 000 mg/kg according to the standard immunization schedules.Results. Oral administration of Homeovox to mice for 14 days at doses of 100 mg/kg and 1 000 mg/kg did not cause significant changes in the main characteristics of immune response compared to controls. When assessing allergenicity, Homeovox at doses 100 mg/kg and 1 000 mg/kg administered according to the standard immunization schedules did not induce systemic anaphylaxis or active skin anaphylaxis in albino guinea pigs. The immunization of guinea pigs by Homeovox at the same doses in a mixture with Freund's complete adjuvant caused no delayed allergic reactions. Homeovox at a single oral dose of 1 000 mg/kg significantly decreased concanavalin A-induced inflammation in CBA mice by 58.4 %.Conclusion. Within the dosage range investigated, Homeovox does not induce immunotoxicity, immediate- or delayed-type allergic or pseudoallergic reactions.
Émile Zola’s Climate History of the Second Empire
Authors: Ungelenk Johannes 
Published: April 2020

This article looks at Émile Zola’s novel cycle Les Rougon-Macquart and argues that it describes its subject, the Second Empire, as a warming climate tending toward climate catastrophe. Zola’s affinity to the notion of climate is shown to be linked to his poetic employment of the concept of ‘milieu’, inspired by Hippolyte Taine. Close readings of selected passages from the Rougon-Macquart are used to work out the climatic difference between ‘the old’ and ‘the new Paris’, and the process of warming that characterises the Second Empire. Octave Mouret’s department store holds a special place in the article, as it is analysed through what the article suggests calling a ‘meteorotopos’: a location of intensified climatic conditions that accounts for an increased interaction between human and non-human actors. The department store is also one of the many sites in the novel cycle that locally prefigure the ‘global’ climate catastrophe of Paris burning, in which the Second Empire perishes.
relation éducative, au carrefour du social, de l’institutionnel et de l’affectif
Authors: AMMOR Samira 
Published: April 2020

Cette contribution questionne, sur un plan épistémologique, le fonctionnement des inégalités sociales à l’école et les facteurs qui interfèrent pour les accentuer au niveau scolaire ou, au contraire, les limiter. Dans cette analyse, un premier focus sera porté sur le déterminisme social en tant qu’approche expliquant cette reproduction. Nous questionnerons, alors, son fonctionnement au niveau de l’école. Comment interfère-t-il avec le contexte scolaire ? Quels sont les facteurs qui le renforcent ? Quels sont les facteurs qui le réduisent ? Comment s’articule-t-il avec l’effet institution, ainsi que l’effet enseignant dans la réussite des élèves ?
Dans un deuxième temps, nous aborderons la relation éducative en tant que variable des performances scolaires agissant au croisement entre le social, l’institutionnel et le psychoaffectif. Nous interrogerons, pour cela, les déterminants de la relation entre enseignants et élèves, leurs modes interactifs, et leurs répercussions sur la réussite, ou l’échec, des élèves. Comment fonctionne la relation au niveau des représentations et attitudes des enseignants vis à vis de leurs élèves ? Par quels mécanismes et quelles interférences avec les facteurs sociaux et institutionnels ? Comment se structure l’effet enseignant dans une institution scolaire inégalitaire ? Enfin, est-elle suffisamment agissante pour arriver à aiguillonner, dans certains cas, la destinée scolaire des élèves, au point d’exercer sur eux l’effet Pygmalion, ou au contraire développer un processus de résilience ?
H2O2-induced Greenhouse Warming on Oxidized Early Mars
Authors: Ito Yuichi , Hashimoto George L. , Takahashi Yoshiyuki O. , Ishiwatari Masaki , Kuramoto Kiyoshi 
Published: April 2020

Abstract
The existence of liquid water within an oxidized environment on early Mars has been inferred by the Mn-rich rocks found during recent explorations on Mars. The oxidized atmosphere implied by the Mn-rich rocks would basically be comprised of CO2 and H2O without any reduced greenhouse gases such as H2 and CH4. So far, however, it has been thought that early Mars could not have been warm enough to sustain water in liquid form without the presence of reduced greenhouse gases. Here, we propose that H2O2 could have been the gas responsible for warming the surface of the oxidized early Mars. Our one-dimensional atmospheric model shows that only 1 ppm of H2O2 is enough to warm the planetary surface because of its strong absorption at far-infrared wavelengths, in which the surface temperature could have reached over 273 K for a CO2 atmosphere with a pressure of 3 bar. A wet and oxidized atmosphere is expected to maintain sufficient quantities of H2O2 gas in its upper atmosphere due to its rapid photochemical production in slow condensation conditions. Our results demonstrate that a warm and wet environment could have been maintained on an oxidized early Mars, thereby suggesting that there may be connections between its ancient atmospheric redox state and possible aqueous environment.
Necroplanetology: Simulating the Tidal Disruption of Differentiated Planetary Material Orbiting WD 1145+017
Authors: Duvvuri Girish M. , Redfield Seth , Veras Dimitri 
Published: April 2020

Abstract
The WD 1145+017 system shows irregular transit features that are consistent with the tidal disruption of differentiated asteroids with bulk densities

and bulk masses

. We use the open-source N-body code REBOUND to simulate this disruption with different internal structures: varying the core volume fraction, mantle/core density ratio, and the presence/absence of a thin low-density crust. We allow the rubble pile to partially disrupt and capture lightcurves at a specific point during the disruption at cadences comparable to those from ground-based photometry. As a proof-of-concept we show that varying these structural parameters have observationally distinguishable effects on the transit lightcurve as the asteroid is disrupted and compare the simulation-generated lightcurves to data from Gary et al. With the caveat that our simulations do not model the sublimation in detail or account for its effects on orbital evolution, we find that a low core fraction and low mantle/core density ratio asteroid is most consistent with the stable transit feature present for multiple weeks circa 2016 April (referred to as G6121 in Gary et al. and A1 in Hallakoun et al.). Connecting tidal disruption simulations to photometry suggests characteristics for the interior structure and composition of an exoplanetary body, information that is only possible because we are observing the death of the planetary system in action. All-sky survey missions such as TESS and LSST will be able to detect other systems like WD 1145+017, creating a sample of subjects for a new subfield of planetary science: necroplanetology.
The Role of Quasar Radiative Feedback on Galaxy Formation during Cosmic Reionization
Authors: Chen Huanqing 
Published: April 2020

Abstract
Recent observations have found that many z ∼ 6 quasar fields lack galaxies. This unexpected lack of galaxies may potentially be explained by quasar radiation feedback. In this paper, I present a suite of 3D radiative transfer cosmological simulations of quasar fields. I find that quasar radiation suppresses star formation in low-mass galaxies, mainly by photodissociating their molecular hydrogen. Photo-heating also plays a role, but only after ∼100 Myr. However, galaxies that already have stellar mass above 105
M
⊙ when the quasar turns on will not be suppressed significantly. Quasar radiative feedback suppresses the faint end of the galaxy luminosity function (LF) within 1 pMpc, but to a far lesser degree than the field-to-field variation of the LF. My study also suggests that by using the number of bright galaxies (

< −16) around quasars, we can potentially recover the underlying mass overdensity, which allows us to put reliable constraints on quasar environments.

Published: April 2020

Abstract
We present new Doppler images of both components of the double-lined binary σ
2 CrB, based on the high-resolution spectroscopic data collected during 11 nights in 2015 March–April. The observed spectra form two independent data sets with sufficient phase coverage. We apply the least-squares deconvolution to all observed spectra to obtain high signal-to-noise mean profiles, from which we derive the Doppler images of both components of σ
2 CrB simultaneously. The surfaces of both F9 and G0 components are dominated by pronounced polar spots. The F9 component exhibits a weak spot at latitude 30° and its mid-to-low latitudes are relatively featureless. The G0 star shows an extended spot structure at latitude 30°, and its surface spot coverage is larger than that of the F9 star, which suggests a higher level of magnetic activity. With the cross-correlation method, we derive a solar-like surface differential rotation on the G0 star of σ
2 CrB for the first time, and the surface shear rate is ΔΩ = 0.180 ± 0.004 rad days−1 and α = ΔΩ/Ωeq = 0.032 ± 0.001. We do not obtain a clear surface shear law for the F9 star due to the lack of mid-to-low latitude features, but detect a systematic longitude shift of high-latitude spots, which indicates a slower rotation with respect to the corotating frame.
Flare Energy Release at the Magnetic Field Polarity Inversion Line during the M1.2 Solar Flare of 2015 March 15. II. Investigation of Photospheric Electric Current and Magnetic Field Variations Using HMI 135 s Vector Magnetograms
Authors: Sharykin I. N. , Zimovets I. V. , Myshyakov I. I. 
Published: April 2020

Abstract
This work is a continuation of Paper I and is devoted to the analysis of nonthermal electron dynamics and plasma heating in the confined M1.2 class solar flare SOL2015-03-15T22:43, revealing energy release in the highly sheared interacting magnetic loops in the low corona, above the polarity inversion line (PIL). The aim of the present work is to perform the first extensive quantitative analysis of the photospheric magnetic field and photospheric vertical electric current (PVEC) dynamics in the confined flare region near the PIL using new vector magnetograms obtained with the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory with a high temporal resolution of 135 s. Data analysis reveals sharp changes of the magnetic structure and PVEC associated with flare onset near the PIL. It is found that the strongest plasma heating and electron acceleration are associated with the largest increase in the magnetic reconnection rate, total PVEC, and effective PVEC density in the flare ribbons. Observations and nonlinear force-free field extrapolations show that the magnetic field structure around the PIL is consistent with a tether-cutting magnetic reconnection (TCMR) geometry. We give a qualitative interpretation of the observed dynamics of the flare ribbons, magnetic field, PVEC, and electron acceleration within the TCMR scenario.

Published: April 2020

Background: Mesenchymal stem cells (MSCs) migrate and transmigrate to acute liver failure (ALF) area due to vascular endothelial growth factor (VEGF) stimulation as an attractant molecule then actively giving the paracrine signaling and or differentiating into primary hepatocytes, however the best route of MSCs transplanted to liver injury area remains unclear.
&nbsp;
Aim: In this study we compare intravenous (IV) and intraperitoneal (IP) route of MSCs administration by analyzing serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT) and bilirubin level as improvement markers of liver function and VEGF as attractant-proliferation molecule on days 2 and 5.
&nbsp;
Materials and methods: Eighteen male Sprague-Dawley rats weighting 200 g were used in this study. They were divided in three study groups: vehicle control, IP and IV groups. The IV group was treated by MSCs at dose 1&times;106 by lateral tail vein injection and IP group received 1&times;106 MSCs via IP injection. The level of SGPT, SGOT and bilirubin were measured by an automatic analyzer, the VEGF level using enzyme-linked immunosorbent assay (ELISA), while the CD73 expression was evaluated using immunohistochemistry.
&nbsp;
Results: This study showed that IV injection of MSCs was more efficient for increasing liver function than IP treatment group that confirmed by the observed significant decrease in SGPT, SGOT and bilirubin level on days 2 and 5 (p<0.001). This effect was most likely mediated by the significant increase of VEGF level (p<0.05) on days 2 and 5.
&nbsp;
Conclusion: Our result conclude that an IV administration of MSCs was more efficacious than the IP administration for liver injury &nbsp;regeneration.&nbsp;
La transmission de la fécondité dans le contexte béarnais, du XVIII e au XX e siècle
Authors: Darlu Pierre 
Published: April 2020

Après une recension des divers travaux publiés dans la littérature depuis le début du xx e siècle sur la question de la transmission intergénérationnelle de la fécondité, les données généalogiques d’un village du Béarn recueillies entre 1652 à 1975 sont présentées et mises à profit pour calculer les variations du nombre d’enfants « utiles », c’est-à-dire ceux qui, à leur tour, ont des enfants, et les corrélations entre la fécondité des parents et celle de leurs enfants. Ces calculs sont présentés en fonction de la période, du statut professionnel des unions, des conditions de transmission de leurs biens (la « maison » et les terres) et du degré de parenté généalogique. Il en ressort que la corrélation entre le nombre d’enfants utiles des parents et celui de leurs enfants est la plus élevée dans les familles d’agriculteurs ayant hérité de la « maison » et possédant des boucles de parenté dans leur ascendance. Ces résultats peuvent être interprétés comme relevant d’une stratégie assurant la stabilité temporelle des structures de la société dans le contexte rural et culturel particulier du Béarn.
