Authors: Gao Jinhua , Bai Yu , Cui Haifeng , Zhang Yu
Published: July 2020

Runoff and soil erosion are serious environmental issues in farmland management. In a field experiment in Xingmu, China, data from nine plots with different slopes and crops were collected, and the crops' leaf area index (LAI) used to represent the impact of vegetation on runoff and soil erosion. The results show that slope and crop both have significant effects on runoff and soil erosion, and that the LAI can indicate the effects of different crops.

Population growth has led to an increase in the production and use of synthetic compounds such as drugs, whose different classes are being investigated. However, the antiretrovirals are still poorly studied. Since the conventional treatments used in the effluent treatment plants have not been able to degrade these substances, other treatment techniques have been evaluated. Therefore, the objective of this work was to study and optimize the use of advanced oxidative processes (AOPs) in the degradation of lamivudine. It was found, initially, that the photo-peroxidation degraded 69% of the compound after 60 min of exposure to UV-C radiation, and that after evaluating the effect of the [H2O2], a degradation of 95% was achieved by using 250 mg L−1 of this reagent. The reaction kinetics showed a good fit to the pseudo-first-order model, and the artificial neural network MLP (3-12-1) demonstrated a good accuracy, managing to predict percentages of degradation for the studied AOP. Toxicity tests indicated an increase in the toxic effect on seeds, but the same was not observed in relation to enterobacteria. In general, the appropriateness of the application of AOP in the degradation of the aqueous solution has been demonstrated, with the largest studies regarding the effects of toxicity.

Published: July 2020

Many patients undergo surgery under general anaesthesia each day. One of the high-priority tasks for an anesthesiologist is to protect tissues from a systemic inflammatory reaction or oxidative distress (including ischaemia/reperfusion). This review aims to demonstrate the anti-inflammatory and antioxidant properties of general anaesthesia in experimental and clinical studies.Halogenated anaesthetics lead to the inactivation of glycogen synthase kinase-3β (GSK-3β), a key enzyme in the implementation of cellular damage mechanisms and systemic inflammatory response syndrome (SIRS). These mechanisms are implemented through the transcription factor nuclear factor (NF)-κB. As a result of NF-κB activation, gene expression responsible for proinflammatory cytokine synthesis follows, activating leukocytes and disrupts endothelial cell junctions, leading to a disruption of the endothelial barrier, leukocyte infiltration into tissues, and the development of SIRS. Furthermore, GSK-3β phosphorylation causes an increase in the level in neuronal cells and hepatocytes of transcription factor Nrf2, which is a master regulator of enzyme levels of antioxidant defence in the cell.Thus, halogenated anaesthetics interfere with different elements responsible for the implementation of SIRS and oxidative distress in addition to limiting disturbing factors during the development of multiorgan failure and endothelial dysfunction in experimental sepsis and a model of ischaemia/reperfusion. Understanding these processes can help to reduce many complications during the post-operative period.Received 9 January 2020. Revised 6 April 2020.

Possibility of hybrid surgery for haemodynamic correction in a child with left heart hypoplasia syndrome: Clinical observation
Authors: Neverova Yu. , Tarasov R. , Khalivopulo I.
Published: July 2020

Owing to the development of prenatal diagnosis and interventional cardiology, newborns can survive complex palliative surgical procedures. Modern methods make it possible to change the principles of treatment for children undergoing haemodynamic correction, the last surgery being Fontan operation, and also stimulate the development of hybrid interventions (catheter procedures and surgical operations in the neonatal period). This article presents the dynamic monitoring of a child diagnosed with left heart hypoplasia syndrome, who underwent Norwood surgery at the age of 2 weeks, followed by restenosis of the distal anastomosis and balloon dilatation of neo-aorta restenosis with installation of a cobalt-chromium balloon-expandable stent (Andrastent XL) along with pararectal left-side access to the infrarenal section of the aorta at 11 months in order to reduce surgical risk and prepare for the next stage of correction (Glenn and Fontan operations).Received 18 March 2020.

Published: July 2020

Pancreatic ductal adenocarcinoma (PDA) has one of the worst prognosis and higher mortality
among most cancers. The diagnosis of PDA is frequently delayed due to a lack of specific biomarkers,
and the efficacy of current chemotherapeutic drugs is limited. Moreover, chemotherapy is
generally applied in advanced stages, where metastatic spread has already occurred. Nanotechnologybased
systems are allowing to advance in the diagnosis and treatment of PDA. New nanoformulations
have shown to improve the activity of conventional chemotherapeutic agents, such as gemcitabine,
and new antitumor drugs, protecting them from degradation, improving their selectivity, solubility and
bioavailability, and reducing their side effects. Moreover, the design of nanocarriers represents a new
way to overcome drug resistance, which requires a comprehensive understanding of the tumor microenvironment
of PDA. This article reviews the current perspectives, based on nanomedicine, to address
the limitations of pancreatic cancer treatment, and the futures lines of research to progress in the control
of this disease.
Targeting NUPR1 for Cancer Treatment: A Risky Endeavor
Authors: Mansour Salma M.A. , Ali Sahar A. , Nofal Shaira , Soror Sameh H.
Published: July 2020

NUPR1 is a transcription factor that has attracted great attention because of its various
roles in cancer. Several studies were carried out to determine its molecular targets and mechanism of
action to develop novel therapies against cancer. Here, we shed light on the role of NUPR1 in different
types of cancer. NUPR1 regulates a complex network of pathways that may be affected by its silencing,
which can cause varying effects. Its role in some types of cancer has been reported but remains
incompletely understood, whereas its roles in other types of cancers have not been reported
yet. Therefore, targeting NUPR1 for cancer treatment remains challenging and risky.
Pathophysiological Mechanisms Underlying Excess Risk for Diabetes and Cardiovascular Disease in South Asians: The Perfect Storm
Authors: Mehta Anurag , Singh Sumitabh , Saeed Anum , Mahtta Dhruv , Bittner Vera A. , Sperling Laurence S. , Virani Salim S.
Published: July 2020

Background:

South Asians are at a significantly increased risk of type 2 diabetes (T2D) and
cardiovascular disease (CVD), are diagnosed at relatively younger ages, and exhibit more severe disease
phenotypes as compared with other ethnic groups. The pathophysiological mechanisms underlying T2D
and CVD risk in South Asians are multifactorial and intricately related.

Method:

A narrative review of the pathophysiology of excess risk of T2D and CVD in South Asians.

Result:

T2D and CVD have shared risk factors that encompass biological factors (early life influences,
impaired glucose metabolism, and adverse body composition) as well as behavioral and environmental
risk factors (diet, sedentary behavior, tobacco use, and social determinants of health). Genetics and epigenetics
also play a role in explaining the increased risk of T2D and CVD among South Asians. Additionally,
South Asians harbor several lipid abnormalities including high concentration of small-dense
low-density lipoprotein (LDL) particles, elevated triglycerides, low high-density lipoprotein (HDL)-
cholesterol levels, dysfunctional HDL particles, and elevated lipoprotein(a) that predispose them to
CVD.

Conclusion:

In this comprehensive review, we have discussed risk factors that provide insights into the
pathophysiology of excess risk of T2D and CVD in South Asians.
Serum Carboxypeptidase N1 Serves as a Potential Biomarker Complementing CA15-3 for Breast Cancer
Authors: Cui Ranliang , Wang Chaomin , Zhao Qi , Wang Yichao , Li Yueguo
Published: July 2020

Background:

The incidence and mortality of breast cancer are increasing annually. Breast cancer
seriously threatens women's health and quality of life. We aimed to measure the clinical value of CPN1, a new
serum marker of breast cancer and to evaluate the efficacy of CPN1 in combination with CA15-3.

Methods:

Seventy samples of breast cancer with lymph node metastasis, seventy-three samples of nonmetastatic
breast cancer and twenty-five samples of healthy human serum were collected. Serum CA15-3 concentration
was determined by Roche Elecsys, and serum CPN1 concentration was determined by ELISA.

Results:

In breast cancer patients, serum CPN1 concentration was positively correlated with tumour size, clinical
stage and CA15-3 concentration (r = 0.376, P<0.0001). ROC curve analysis showed that the optimal critical
concentration of CPN1 for breast cancer diagnosis was 32.8pg/ml. The optimal critical concentration of CPN1
in the diagnosis of metastatic breast cancer was 66.121pg/ml. CPN1 has a greater diagnostic ability for breast
cancer (AUCCA15-3=0.702 vs. AUCCPN1=0.886, P<0.0001) and metastatic breast cancer (AUCCA15-3=0.629 vs.
AUCCPN1=0.887, P<0.0001) than CA15-3, and the combined detection of CA15-3 and CPN1 can improve the
diagnostic efficiency for breast cancer (AUCCA15-3+CPN1=0.916) and for distinguishing between metastatic and
non-metastatic breast cancer (AUCCA15-3+CPN1=0.895).

Conclusion:

CPN1 can be used as a new tumour marker to diagnose and evaluate the invasion and metastasis of
breast cancer. The combined detection of CPN1 and CA15-3 is more accurate and has a certain value in clinical
application.
A sala de aula sob a vontade da neutralidade de sentidos
Authors: Hashiguti Simone Tiemi , Lemes Fabiane , Ângelo Rogério de Castro
Published: July 2020

RESUMO: Em meio às disputas políticas entre partidos conservadores e progressistas nos últimos anos, a sala de aula tem sido um espaço de intensa disputa de sentidos. Uma interpretação que tem sido frequente sob a ótica conservadora é a de que, ao invés de ser um espaço politicamente neutro, a sala de aula tem sido lugar de doutrinação política, ideológica e moral por parte de docentes. Uma das iniciativas que visa a legislar contra o que foi chamado de “abuso da liberdade de ensinar” é o Programa Escola Sem Partido. Neste artigo, a partir de uma perspectiva discursiva de linguagem, realizamos uma análise discursiva do site informativo desse programa. Observamos, intra e interdiscursivamente, como a escola, os conteúdos didáticos, o professorado e o alunado são objetificados a partir de um ideal de língua como instrumento de comunicação e de sala de aula como ambiente do sujeito-suposto-saber, controlado e consciente.
Escola sem partido: neoliberalismo e conservadorismo de mãos dadas
Authors: Santos Maria Escolástica de Moura , Santos Pedro Pereira dos
Published: July 2020

Este texto tem como objetivo compreender o movimento Escola sem Partido (ESP), situando-o no contexto da crise estrutural do capital, para desvelarmos as ideologias contidas em seu conteúdo. Trata-se de uma pesquisa bibliográfica e nela buscamos explicitar o momento em que ganha força o discurso e a militância ultraconservadora, bem como sua relação com a lógica neoliberal. Não por acaso, o discurso que defende a família, os valores religiosos, o ataque às ciências, é o mesmo que defende as políticas de austeridade fiscal, a ampliação da margem de atuação da iniciativa privada e a retirada de direitos da classe trabalhadora, ou seja, a privatização e o Estado mínimo. Portanto, faz-se necessário entender que o Escola sem Partido (ESP) se apresenta como instrumento de controle social da burguesia, que utiliza a educação como forte aliada no processo de manipulação de indivíduos, visando à manutenção do projeto societário em curso.
Comportamiento fisiológico de gramíneas forrajeras bajo tres niveles de humedad en condiciones de casa malla
Authors: Atencio Liliana Maria , Tapia José Jaime , Mejía Sergio , Cadena Torres Jorge
Published: July 2020

La presente investigación tuvo como objetivo evaluar el efecto del nivel de humedad sobre el comportamiento fisiológico de diferentes gramíneas forrajeras. El experimento se realizó bajo condiciones de casa de malla en el Centro de Investigación Turipaná de Corpoica, (Cereté, Córdoba). Se utilizó un diseño de bloques completos al azar con 14 genotipos y tres (3) repeticiones. Se utilizaron tres regímenes de humedad, a manera de localidades dentro de la misma casa de malla. Dentro de las variables en estudio se encontraron: fotosíntesis neta, transpiración, conductancia estomática, potencial hídrico foliar, masa seca de hoja, área foliar, entre otras. Sólo las variables área foliar y potencial hídrico foliar presentaron interacciones significativas entre los factores Genotipo y Ambiente de humedad, mientras que el resto de variables, generalmente fueron afectadas por los factores principales (p<0.05). Los genotipos Bisset, Colosuana y Strikcland generaron la interacción para área foliar al presentar valores altos en condiciones de alta y media humedad. En el nivel de humedad bajo, las 14 gramíneas forrajeras presentaron los potenciales hídricos foliares más negativos. En este nivel se obtuvieron también los menores valores de conductancia estomática y transpiración y las menores acumulaciones de materia seca en todos los órganos, principalmente las hojas. BR02/1752 presentó la mayor acumulación de materia seca en las hojas (32,67 g/planta-1), seguido de CIAT16051 (27,78 g/planta-1). Se concluye que el comportamiento fisiológico de las pasturas está determinado por las características genéticas y por el régimen de humedad implementado, y no por su interacción.

Authors: Barrera Violeth José Luís , Fernández Herrera Claudio , Pérez garcía Karol Darío
Published: July 2020

El banano, principal producto de exportación en Colombia, presenta muchos retos técnicos como el control de la tortuguilla (Colaspis sp.), causante del 33% de pérdidas económicas; dado que los estándares de calidad no permiten la presencia de residuos químicos presentes en los frutos, se evaluó en un cultivo comercial, del municipio de los Córdobas, el efecto de extractos vegetales en el manejo de la tortuguilla. Se evaluó la severidad del ataque a partir del número de roeduras en frutos y la incidencia en racimos y frutos tratados. Los extractos utilizados fueron salvia Salvia officinalis L., anamú Petiveria alliacea L., albahaca Ocimum basilicum L., ajo Allium sativum L. y ají picante Capsicum annuum asperjados con una bomba tipo jardinera sobre bolsas comerciales de polietileno; dejándose expuestas durante una hora para asegurar la adherencia del producto. Se estableció un diseño completamente al azar con siete tratamientos, tres repeticiones, un testigo relativo (bolsa sin extracto vegetal) y un testigo absoluto (racimos sin embolsar); registrando la severidad del daño causado. Los resultados mostraron que los frutos provenientes de racimos embolsados presentaron menor severidad que los frutos no embolsados y los tratamientos constituidos por bolsas impregnadas con extracto de ajo presentaron menor incidencia y grado de severidad, mostrando una disminución del daño en un 98%. Concluyendo que el extracto de ajó fue el producto repelente que mejor acción mostro al daño de fruto. Los tratamientos donde se aplicó Albaca, Ají, Salvia y Anamú se pudieron determinar una mayor incidencia y daño de fruto.

El distrito de La Doctrina-Córdoba, aporta a la economía colombiana, con cultivos de arroz (1.230 ha), maíz (50ha), palma africana (300 ha), papaya (10 ha), hortalizas (8 ha) y 400 ha de pastos. Estos cultivos utilizan plaguicidas ocasionando contaminación en los canalesde riego, dichas aguas son utilizadas por los pobladores para uso doméstico y consumo humano. El objetivo de esta investigación fue evaluar las concentraciones de plaguicidas organoclorados (POCls), organofosforados (POFs) y cipermetrina (CP) en aguas de los canales de riego del distrito de La Doctrina en dos épocas del año (seca y lluviosa). Los análisis fueron realizados por Cromatografía de gases y Gases-Masas. La CP se detectó por monitoreo de masas SIM, los POCls y POFs se analizaron con detector de captura de electrones (ECD) y nitrógeno-fosforo (NPD) respectivamente. Los resultados mostraron que todas las concentraciones de CP (época-seca) están por encima del límite aceptado según la norma colombiana para agua potable, según la norma Argentina todos sobrepasan los límites permisibles. Entre los POCls solo el Endrín sobrepasó la norma colombiana, no se encontraron POFs. Los porcentajes de aparición individual de plaguicidas muestran el valor más alto para cipermetrina con un 73%. Las altas concentraciones de CP y POCls, en el agua de riego en el distrito La Doctrina, generan un alto interés por la detección de las concentraciones de estos contaminantes es alimentos como el arroz y un alto riesgo a la salud humana.
Diseño de un modelo de articulación entre la cadena productiva hortofruticola colombiana y la cadena logística de frio
Authors: Flórez Martínez Diego Hernando
Published: July 2020

El objetivo de esta investigación es proponer un modelo de articulación, entre la cadena productiva (CP) hortofrutícola colombiana como mecanismo de gestión de las interacciones entre actores para el flujo de materiales y la cadena de frío (CF) como herramienta logístico-tecnológica, para la conservación de alimentos perecederos. A partir de una metodología secuencial de construcción, se propone un modelo de eslabones y segmentos para el sector hortofrutícola colombiano, que integra las actividades desde los proveedores de insumos hasta el cliente o consumidor final, identificando sus descriptores. Posteriormente se analizan los modelos de cadena de frío propuestos en la literatura conceptualización e identificación de puntos críticos de control tanto exógenos como endógenos con base en el sistema de análisis de riesgos y puntos críticos de control (HACCP), seleccionando el modelo de cadena sincronizada. El análisis conjunto y superpuesto de estos dos modelos, se convierte en el diseño articulado, que permite direccionar la adaptación de tecnología de transporte y almacenamiento de productos bajo condiciones de temperatura y humedad determinadas dentro de la cadena productiva hortofrutícola, como factor de ventaja competitiva.

Published: July 2020

Una alternativa para disminuir el efecto de la fertilización química en los suelos y favorecer el crecimiento de los cultivos de batata es la incorporación de microorganismos promotores de crecimiento vegetal en la fertilización. En el Caribe Colombiano actualmente, la batata es uno de los cultivos emergentes debido a sus altas propiedades nutritivas en la dieta humana. El objetivo de este estudio fue evaluar el efecto de dos cepas bacterianas Pseudomonas denitrificans IBVS2  y Azotobacter vinelandii IBVS13 en el rendimiento de batata clon Tainung 66 en condiciones de campo, en el Valle del Sinú, Córdoba, Colombia.  La investigación se desarrolló en segundo semestre del 2017, en el Centro de Investigación Turipaná-Agrosavia, utilizando esquejes apicales del clon Tainung 66, donde se implementó un diseño en bloques completos al azar con un arreglo factorial 3x2+2, evaluando variables del componente fisiológico, análisis químico foliar y edáfico, rendimiento y composición bromatológica. Los resultados mostraron que las variables rendimiento y masa seca radicular presentaron diferencias significativas con respecto al testigo químico cuando se implementó la fertilización empleando la cepa IBVS2 más 50% del fertilizante químico, obteniendo un rendimiento de 11,32 t.ha-1 y  5,78 t.ha-1 respectivamente. Estos resultados demuestran que la inoculación de PGPRs constituye una alternativa en el cultivo de batata, con efectos positivos al compararlo con la práctica de fertilización química completa.
Understanding the Dimensions of Medical Crowdfunding: A Visual Analytics Approach
Authors: Ren Jie , Raghupathi Viju , Raghupathi Wullianallur
Published: July 2020

Background

Medical crowdfunding has emerged as a growing field for fundraising opportunities. Some environmental trends have driven the emergence of campaigns to raise funds for medical care. These trends include lack of medical insurance, economic backlash following the 2008 financial collapse, and shortcomings of health care regulations.

Objective

Research regarding crowdfunding campaign use, reasons, and effects on the provision of medical care and individual relationships in health systems is limited. This study aimed to explore the nature and dimensions of the phenomenon of medical crowdfunding using a visual analytics approach and data crawled from the GoFundMe crowdfunding platform in 2019. We aimed to explore and identify the factors that contribute to a successful campaign.

Methods

This data-driven study used a visual analytics approach. It focused on descriptive analytics to obtain a panoramic insight into medical projects funded through the GoFundMe crowdfunding platform.

Results

This study highlighted the relevance of positioning the campaign for fundraising. In terms of motivating donors, it appears that people are typically more generous in contributing to campaigns for children rather than those for adults. The results emphasized the differing dynamics that a picture posted in the campaign brings to the potential for medical crowdfunding. In terms of donor’s motivation, the results show that a picture depicting the pediatric patient by himself or herself is the most effective. In addition, a picture depicting the current medical condition of the patient as severe is more effective than one depicting relative normalcy in the condition. This study also drew attention to the optimum length of the title. Finally, an interesting trend in the trajectory of donations is that the average amount of a donation decreases with an increase in the number of donors. This indicates that the first donors tend to be the most generous.

Conclusions

This study examines the relationship between social media, the characteristics of a campaign, and the potential for fundraising. Its analysis of medical crowdfunding campaigns across the states offers a window into the status of the country’s health care affordability. This study shows the nurturing role that social media can play in the domain of medical crowdfunding. In addition, it discusses the drivers of a successful fundraising campaign with respect to the GoFundMe platform.

Published: July 2020

Background

Current guidelines emphasize an active lifestyle in the management of knee osteoarthritis (OA), but up to 90% of patients with OA are inactive. In a previous study, we demonstrated that an 8-week physiotherapist (PT)-led counseling intervention, with the use of a Fitbit, improved step count and quality of life in patients with knee OA, compared with a control.

Objective

This study aimed to examine the effect of a 12-week, multifaceted wearable-based program on physical activity and patient outcomes in patients with knee OA.

Methods

This was a randomized controlled trial with a delay-control design. The immediate group (IG) received group education, a Fitbit, access to FitViz (a Fitbit-compatible app), and 4 biweekly phone calls from a PT over 8 weeks. Participants then continued using Fitbit and FitViz independently up to week 12. The delay group (DG) received a monthly electronic newsletter in weeks 1 to 12 and started the same intervention in week 14. Participants were assessed in weeks 13, 26, and 39. The primary outcome was time spent in daily moderate-to-vigorous physical activity (MVPA; in bouts ≥10 min) measured with a SenseWear Mini. Secondary outcomes included daily steps, time spent in purposeful activity and sedentary behavior, Knee Injury and OA Outcome Score, Patient Health Questionnaire-9, Partners in Health Scale, Theory of Planned Behavior Questionnaire, and Self-Reported Habit Index.

Results

We enrolled 51 participants (IG: n=26 and DG: n=25). Compared with the IG, the DG accumulated significantly more MVPA time at baseline. The adjusted mean difference in MVPA was 13.1 min per day (95% CI 1.6 to 24.5). A significant effect was also found in the adjusted mean difference in perceived sitting habit at work (0.7; 95% CI 0.2 to 1.2) and during leisure activities (0.7; 95% CI 0.2 to 1.2). No significant effect was found in the remaining secondary outcomes.

Conclusions

A 12-week multifaceted program with the use of a wearable device, an app, and PT counseling improved physical activity in people with knee OA.

Knowledge Capital Accumulations and Employee Involvement Work Systems—Does Workplace Culture Have a Role?
Authors: Rondeau Kent V. , Wagar Terry H.
Published: July 2020

Knowledge capital accumulations are impacted by a variety of workplace factors, including the human resource management work system and the workgroup culture in which it is embedded. Organizations adopting high-involvement work systems stressing employee participation, empowerment, commitment, and accountability have the potential to produce, and to be a beneficiary of, greater stores of employee intellectual capital. The role of workplace culture in this relationship is potentially salient but its operational characteristics require further elucidation. Using a competing values framework to characterize workplace culture, four culture archetypes can be specified: hierarchical, market, entrepreneurial, and clan. Results from step-wise regression analysis show that the four workplace culture archetypes contribute differentially to intellectual capital stores, yet only the clan and entrepreneurial culture archetypes partially mediates this relationship.

Published: July 2020

Los métodos de obtención de nanoestructuras han sido un área de estudio fundamental desde el inicio del auge de la nanotecnología. La biosíntesis de nanoestructuras se inspira en los mecanismos que tienen algunos microorganismos y plantas para subsistir en ambientes con estrés químico. En el presente trabajo se presentan resultados novedosos que ha logrado nuestro grupo de investigación para generar nanoestructuras de Au y Ag con una morfología fácilmente sintonizable a partir de los extractos de té verde (Camellia sinensis), y hierba del manso (Anemopsis californica), como agentes reductores de los iones Au+3 y Ag+1; así como la obtención de nanopartículas de magnetita (Fe2O3) con un control de tamaño y de fase superior a lo reportado en literatura para métodos biogénicos. Adicionalmente se demuestra el uso efectivo de biotemplates para diseñar materiales nanoestructurados con métodos de síntesis verde. Finalmente se exhibe evidencia de los nanomateriales obtenidos por biosíntesis en base a la caracterización con Microscopía Electrónica de Transmisión, Microscopía Electrónica de Barrido y Espectroscopia de Dispersión de Energía de Rayos-X.
Garantías del Derecho de la Seguridad Social en la República Dominicana vista desde la Constitución y las leyes No.87-01 y 13-20.
Authors: Santos Frías Emilia
Published: July 2020

El Derecho a la Seguridad Social en la República Dominicana, tiene su génesis en normas preconstitucionales, como la Ley No.42-01 General de Salud y la Ley No.87-01, que estableció el Sistema Dominicano de Seguridad Social (SDSS), así como, la Ley No.1-12, que instituyó la Estrategia Nacional de Desarrollo (END-2030).  Este derecho se potencializa luego de la modificación de la Constitución Dominicana en el año 2010, al ser incluido en el texto de la Ley Suprema como un derecho fundamental, en el artículo No.60. Además, al ser un servicio público, el mismo tiene que ser prestado cumpliendo los principios de “universalidad, accesibilidad, eficiencia, transparencia, responsabilidad, continuidad, calidad, razonabilidad y equidad tarifaria, establecidos en el numeral 2 del artículo No.147 de la Ley Suprema.
Los mercados regulados de servicios públicos: privatización y des-regulación

Published: July 2020

El tejocote (Crataegus mexicana) es una planta nativa de México. Su fruto no sólo es utilizado como alimento para el consumo humano, sino también como ornamento en celebraciones y en la medicina tradicional. A pesar de esto, se le considera un cultivo subutilizado y su aporte de compuestos con actividad antioxidante ha sido poco estudiado. El objetivo de este trabajo fue caracterizar e identificar metabolitos secundarios extraídos de las fracciones del fruto para determinar su potencial antioxidante: (1) cáscara, (2) pulpa y (3) semilla. Se cuantificó el contenido de fenoles y flavonoides totales, flavan-3-ol y proantocianidinas. Además, la actividad antioxidante de las tres fracciones fue cuantificada mediante dos métodos: (1) reducción del hierro (FRAP) e (2) inhibición del radical libre 2,2-difenil-1-picrilhidracilo (DPPH). Se identificaron los principales compuestos presentes en cada una de las fracciones a través de cromatografía de líquidos de alta resolución (HPLC). Los resultados indicaron que fue en el extracto de la semilla donde se presentó el mayor contenido de fenoles y flavonoides totales, así como el mejor potencial  antioxidante, el cual estuvo directamente relacionado con el contenido de compuestos extraídos. En las tres fracciones del fruto se registró la presencia de epicatequina, quercetina 3-D-galactósido y ácido ascórbico. Además, en semilla se identificó la catequina y vitexina, mientras que en cáscara y pulpa se observó la presencia de ácido clorogénico y procianidina B2.
Los peninsulares en la intendencia de Guadalajara a fines del siglo XVIII. Origen provincial y composición de una élite dirigente
Authors: Gómez Serrano Jesús
Published: July 2020

El propósito de este artículo es caracterizar a la comunidad peninsular radicada en la intendencia de Guadalajara a fines del siglo xviii, a partir sobre todo de dos ladrones formados por Félix Calleja, referidos a la ciudad de Guadalajara y a la subdelegación de Aguascalientes. Con el deseo de contribuir al debate sobre la conformación de élites y grupos de poder en la Nueva España, se propone una caracterización por número, origen provincial, edad, ocupación y estado civil de las comunidades peninsulares radicadas en esos dos lugares. Al mismo tiempo, para dimensionar y contextualizar adecuadamente la importancia de esas comunidades, se brinda información general sobre el peso y la composición de la población europea en toda la Nueva España. Se plantea que los europeos, a pesar de constituir minorías insignificantes desde el punto de vista estadístico, constituían élites dirigentes que abrigaban un agudo sentimiento de superioridad, gozaban de reconocimiento público y proyectaban su influencia sobre los más diversos aspectos de la vida colectiva.

La entrega del poder de Motecuhzoma. Una propuesta crítica
Authors: Pastrana Flores Miguel Gabriel
Published: July 2020

Este artículo es una revisión crítica de la acción de entrega del poder y sumisión atribuida a Motecuhzoma Xocoyotzin, en favor de Carlos I de España, por intermediación del capitán Hernando Cortés. Este pasaje fundamental en la historia de la conquista de Tenochtitlan ha tenido importantes y trascendentes implicaciones legales, políticas e historiográficas hasta el día de hoy, y por ello ha sido objeto de diversos análisis desde la perspectiva de la cultura europea. Sin embargo, poco se ha explorado el problema, no ya desde la perspectiva jurídica, política, documental e historiográfica española, sino desde lo que se sabe acerca de las instituciones, creencias y prácticas políticas de los antiguos nahuas. Este trabajo estudia la perspectiva náhuatl de la cuestión.
