Authors: Ortega Jerez Sorsireé , Ortega Jerez Arianny 
Published: November 2020

El presente estudio se enfocó en impulsar el Reciclaje en las redes sociales, con el fin de conocer la diversidad de beneficios que trae consigo la clasificación de los desperdicios y proveer a los docentes en formación sobre los elementos necesarios para que incorporen este en su planificación y concientizar a los estudiantes, niños o comunidad en general y por ende, en los espacios online. Desde el punto de vista metodológico, se desarrolló basado en la modalidad de investigación - acción, en el cual se elaboró un plan de acción dividido por semanas, planificando estrategias novedosas en relación a su especialidad (informática) y a su vez correlacionarlas con el reciclaje en el ámbito educativo y en la enseñanza de los educando. Con respecto a los antecedentes de la investigación, las bases y la sustentación de aspectos teóricos vinculados con la investigación en general, se fundamentó en autores y trabajos que se relacionan con el mismo. En tal sentido, las autoras han llegado a la siguiente reflexión: la justificación práctica de la investigación se verá reflejada en el beneficio social que generará a la Comunidad Upelista, puesto que la esencia del mismo está dirigida a brindar ayuda a la comunidad antes mencionada, y de esta forma incentivar su deseo de reciclar, por medio de los propósitos planteados, explicando las ventajas que traerá la puesta en marcha del reciclaje en las comunidades, y al mismo tiempo, explorar los procesos que resaltan las redes sociales como herramienta para llevar a cabo la divulgación del reciclaje, analizando toda la información que los individuos colocan en las comunidades virtuales y propiciando una participación más activa y abierta de los cibernautas e incorporando diversidad de elementos que propician la concientización, los cuales constituyen una nueva forma de adentrarse en la educación.

Published: November 2020

En la última década, se ha incrementado significativamente la oferta y demanda de educación formal y no formal, a través de contenidos digitales mediados por plataformas tecnológicas, herramientas hipermedia, así como el uso indiscriminado de artefactos tecnológicos que hacen cada vez más de la comunicación un medio de relación social, familiar, educativo y laboral. El propósito del presente trabajo es presentar los hallazgos derivados del proyecto de investigación “Diseño de la Metodología para validación de plataforma tecnológica, diseño de contenidos digitales para la Formación en el Trabajo REA”. Dicha Plataforma tecnológica ha sido desarrollada para construir contenidos digitales, entendidos éstos como recursos educativos abiertos y cuya metodología está basada en la investigación evaluativa que permite validar la usabilidad e impacto del uso de contenidos digitales mediados por plataformas tecnológicas en el desarrollo de competencias profesionales y/o laborales. Se considera importante valorar no sólo cómo dichos contenidos digitales aportan, en su estructura, el repertorio de diferentes tipos de saberes (conceptual, procedimental y actitudinal) sino también, valorar desde las dimensiones pedagógica, tecnológica, y de comunicación, si dichos contenidos digitales favorecen o no procesos de interacción humana que se reflejan en aprendizaje autónomo para la toma de decisiones y solución de problemas en el ámbito del trabajo.
Las redes sociales en el contexto académico universitario. Desafíos al docente
Authors: Barba Téllez María Nela , Palacios Trujillo Edinson Patricio 
Published: November 2020

Hoy en las universidades se exigen prácticas educativas innovadoras que aseguren la calidad del proceso de enseñanza aprendizaje. Resulta interesante cuestionarse cuál es la calidad de los entornos de aprendizaje, y el uso académico que hacen los estudiantes y docentes de las redes sociales en las universidades. Mediante la revisión documental se comprobó que en Ecuador la configuración de las redes sociales desde lo pedagógico no se ha logrado en todas las universidades, y que aún no existe consenso entre las universidades sobre los indicadores de calidad que se requieren para evaluar el uso de las redes en los procesos académicos universitarios. Las redes sociales en las universidades ecuatorianas se constituyen en herramientas de generación y retroalimentación de información, en donde el modelo de comunicación resulta eficiente e innovador para el contexto universitario, aunque todavía es necesario continuar masificando su uso y buscar sus utilidades para incorporarlos a los procesos de aprendizaje.
Spectroscopic diagnostics of a high-frequency dielectric barrier discharge of atmospheric pressure in mixtures of cadmium diiodide vapor with neon and small additions of xenon
Authors: Malinina Antonina 
Published: November 2020

Diagnostics of the emission spectra of a gas-discharge plasma of a barrier discharge of atmospheric pressure in mixtures of cadmium diiodide vapor with neon and small additions of xenon is carried out. A gas-discharge plasma was created and the components of the working mixture were excited by a high-frequency barrier discharge at a sinusoidal voltage pulse repetition rate of up to 140 kHz. Emission of exciplex molecules of cadmium monoiodide with a maximum emission at a wavelength of λ = 655 nm and xenon iodide with a maximum of radiation at wavelengths λ = 253 and λ = 320 nm, excimer molecules of iodine, lines of atoms of cadmium, iodine, neon and xenon was revealed. It was found that at temperatures of the mixtures under study above 150 0C, the predominance of radiation from exciplex molecules of cadmium monoiodide is observed. The reason for the increased brightness of the emission of exciplex molecules of cadmium monoiodide in mixtures of cadmium diiodide vapor with neon and xenon additive is established. The regularities in the spectral characteristics of radiation in the mixtures under study are discussed. A high-frequency barrier discharge of atmospheric pressure in mixtures of cadmium diiodide vapor with neon and xenon is of interest for creating a multi-wavelength excilamp in the UV and visible spectral ranges

La contagion et l'anonymat dans les violences collectives
Authors: Kabasha Gaetan 
Published: November 2020

La contagion et l'anonymat sont deux éléments clefs pour comprendre pourquoi la violence part d'un point concret et se répand aux alentours englobant de plus en plus de personnes comme s'il s'agissait d'un feu de brousse. Dans cet article, nous nous proposons de faire une recherche à propos de ces concepts sans lesquels on ne pourrait analyser les violences collectives commises par des personnes qui souvent ne se connaissent par entre elles et ne connaissent pas non plus leurs victimes.

Background: Sulfites including Sodium Metabisulfite (SMB) are commonly used as food preservatives and pharmaceutical products. Despite their worldwide use, there is evidence suggesting their toxicity on human organs and tissues. The purpose of this study was to evaluate the effect of SMB with or without Zingiber officinale (ginger) extract on the rat ovary. Methods: A total of 32 adult, female Wistar rats were divided into four groups of eight each. They consisted of, a) control group, b) ginger group (500 mg/kg/day), c) SMB group (260 mg/kg/day), and d) combined SMB and ginger group at identical doses. After 28 days, the rats were sacrificed and the ovarian tissue Malondialdehyde (MDA), as a marker of lipid peroxidation was measured. The volume and weight of the ovaries and the number of follicles at different stages were counted by stereological methods. Results: The SMB treatment caused a significant decrease in the ovarian volume and the number of follicles with simultaneous increase in the number of degenerate follicles (P≤0.001) and MDA level (P≤0.01). Ginger treatment of the rats exposed to SMB significantly increased the number of follicles at various stages and partially reversed the ovarian tissue level of MDA, compared to that in the control group (P≤0.05). Conclusion: The SMB treatment induced structural changes in the rats’ ovaries and the concomitant treatment with ginger largely reversed the damages caused by SMB.

Background: Kidneys exposure to toxins can cause injuries, leading to their functional impairments. Traditionally, plants have been used for the treatment of renal disorders and numerous medicinal plants have been tested for their nephroprotective effects, in such cases as gentamicin (GM) and cisplatin (Cisp)-induced nephrotoxicity. This study assessed the ability of Acalypha wilkesiana’s extract to counteract its toxic effect based on the biochemical, histological and proinflammatory cytokines components in rats. Methods: Thirty-six male Wistar rats were randomly divided into nine groups (n=4 each) and administered the following treatments: a) normal control (1 mL/kg body weight normal saline from days 1-10); b) nephrotoxin (GM 120 mg/kg, days 2-7; or Cisp 7 mg/kg on day 3); c) standard drug (120 mg/kg Silymarin plus GM or Cisp, days 1-10); and, d) extract groups (100 or 250 mg/kg, days 1-10 plus GM). Blood samples were collected and subjected to hematological and biochemical evaluations while kidney tissue samples were examined for histopathological alterations, pro- and antioxidants, and expression of pro-inflammatory cytokines. Results: Treatment of the rats pre-exposed to GM or Cisp with the extract decreased the serum creatinine, urea and MDA levels. The GST and GPx levels were also restored in rats. Glomerular atrophy with tubular epithelial necrosis induced by either nephrotoxin was restored to near normal. The expression of COX-2 following the administration of either nephrotoxin was reversed after treatment with the extract. Conclusion: The A. wilkesiana extract exhibited significant nephroprotective property, which could potentially be regarded as a promising alternative to the management of renal diseases.

Background and Aim: Tendon, like the skeletal muscle, exhibits mechanical and morphological adaptations resulted from exercise training; however, little is known about the basic cellular and molecular mechanisms that regulate these responses. The aim of the present study was therefore to investigate the effect of 6 weeks of aerobic training on the TGF-β1, myostatin and MMP9 mRNAs expression in the tendon of fast- and slow-twitch muscles. Methods & Materials For this purpose, 12 male Wistar rats at 8 weeks of age were randomly divided into two groups: experimental (n=6) and control (n=6). The exercise group performed aerobic training for 6 weeks, 5 sessions per week. Forty-eight hours after the last training session, all rats were sacrificed and the tendons of soleus and Extensor Digitorum Longus (EDL) muscles were extracted. Expression of TGF-β1, myostatin and MMP9 mRNAs were assayed using RealTime-PCR. Independent t-test was also used for statistical analysis. Ethical Considerations: All stages of the study were conducted according to the ethical guidelines and authorization of Research Deputy of Islamic Azad University, Central Tehran Branch No. IR.IAU.PS.REC.1398.296. Results: The results showed that the expression of TGF-β1 mRNA in EDL and soleus tendons significantly increased (P≤0.001), whereas the expression of myostatin in EDL tendon was significantly reduced (P≤ 0.001). Increased mRNA expression of MMP9 in the tendon of EDL and soleus muscles was not statistically significant (P>0.05). Conclusion: It seems that aerobic exercise can modulate the expression of genes involved in the regulation of tendon collagen in a muscle type-dependent manner.

Background and Aim: Coronary Heart Disease (CAD) is one of the most important causes of mortality. Exercise activities after coronary artery bypass surgery increase the density of myocardial capillaries called angiogenesis and improve cardiovascular function. The aim of the present study was to determine the effect of aerobic-resistance training on plasma basic fibroblast grown factor levels in post-coronary artery bypass grafting patients. Methods & Materials: The sample consisted of 30 men aged 45-60 years who underwent bypass surgery. They were randomly divided into experimental (n=15) and control (n=15) groups. The experimental group performed aerobic resistance training for eight weeks (3 sessions per week) and the control group did not. Blood samples were taken 24 hours before the start of the first training session and 48 hours after the last training session while all subjects were fasting. In vitro ELISA method was used to measure BFGF. Independent and paired t-test and Shapiro-Wilk test were used to analyze the data at the significant level of 0.05 in SPSS v. 21. Ethical Considerations: This study was registered (Ethics Code: IR.IAU.NEYSHABUR.REC.1398.01) in the Ethics Committee of Islamic Azad University, Neishabour Branch, and with Clinical Trial Code: IRCTID:IRCT20191228045919N1. Results: Eight weeks of aerobic-resistance training significantly increased bFGF levels in the exercise group compared to the control group (P=0.002). Also, pre and post changes in the experimental group showed a significant increase in plasma bFGF levels (P=0.002), which was not significant in the control group (P=0.758). Conclusion: According to the results, it may be concluded that combined (aerobic resistance) exercise may increase angiogenesis and capillary density in post-CABG patients by increasing plasma bFGF levels
Management of Aplastic Anemia in Pregnancy: A Case Report
Authors: Djusad Suskhan , Yoarva Malano  
Published: November 2020

Aplastic anemia was first recognized by Ehrlich in 1888, although the pathogenesis of aplastic anemia has remained elusive. Aplastic anemia is a subtype of anemia characterized by pancytopenia and a hypocellular bone marrow which are the risk factor can be due to chemicals, drugs, infections, irradiation, leukemia, and inherited disorders. There is universal agreement that pregnancy complicated by aplastic anemia is a serious condition. The risk to the mother is mainly in the form of hemorrhage meanwhile the fetus may suffer from growth restriction and even intrauterine death. Most of the fetal complications are due to maternal anemia. We here present one cases of pregnancy complicated by aplastic anemia, which were seen within 3 months at our hospital. This high incidence is because the hospital is a top national care referral unit with good hematology and blood bank support.

Abstrak
Anemia aplastik pertama kali dikenali oleh Ehrlich pada tahun 1888, walaupun patogenesis anemia aplastik masih sulit dipahami. Anemia aplastik adalah subtipe anemia yang ditandai dengan pansitopenia dan hiposeluler sumsum tulang yang merupakan faktor risiko yang dapat disebabkan oleh bahan kimia, obat-obatan, infeksi, iradiasi, leukemia, dan kelainan bawaan. Terdapat kesepakatan universal bahwa komplikasi kehamilan berupa anemia aplastik merupakan kondisi serius. Risiko kepada ibu hamil terutama dalam bentuk perdarahan sementara janin dapat mengalami hambatan dalam pertumbuhan dan bahkan kematian dalam kandungan. Sebagian besar komplikasi janin disebabkan oleh anemia pada maternal. Kami di sini menyajikan satu kasus komplikasi kehamilan berupa anemia aplastik, yang ditemukan dalam waktu 3 bulan di rumah sakit kami. Kejadian yang tinggi ini karena rumah sakit adalah unit rujukan perawatan nasional teratas dengan hematologi yang baik dan dukungan bank darah.
