Entre subjetividad y alteridad en el discurso político en prosa de Gabriela Mistral en la década de 1930
Authors: Rojas Gabriel Arturo Farias , Cavalheiro Juciane Dos Santos 
Published: March 2019

El artículo se propone realizar análisis crítico sobre el discurso político de Gabriela Mistral, operando desde la descolonización del mito creado sobre ella, el cual habrá abierto nuevas miradas al entendimiento de nuestra primer Premio Nobel de Literatura, tanto en Chile como en el resto de los pueblos de Iberoamérica. Para este artículo, fueron seleccionados dos textos en los cuales se revela cómo Gabriela Mistralentendía a una de las más emblemáticas figuras para la América hispánica, a saber, Simón Bolívar. Ambos textos fueron publicados en el periódicoEl Mercurio en 1931: “Bolívar a los 40 años” y “La Ambición de Bolívar”. En términos generales, tratan sobre un perfil biográfico. Sobre estas composiciones incidirá, no la Mistral ideológica, sino la cronotópica, aquella sobre la cual se abre un resplandor de subjetividad. No pesará sobre su memoria la falsificación político biográfica tradicional. Por otro lado, se revelará una nueva narrativa sobre ella, lo que ayudará a mostrar una globalidad alternativa de la autora: la política. Sin embargo, esta nueva narrativa será perceptible como la dinámica de un cronotopo en constante inacabamiento, lo que suspenderá esa biografía monolítica de una Mistral apolítica y conservadora, impuesta desde el mito colonial del ChileRepublicano. *** Entre subjetividade e alteridade no discurso político em prosa de Gabriela Mistral na década de 1930 ***O artigo se propõe a realizar análise crítica sobre o discurso político de Gabriela Mistral, operando desde a descolonização do mito criado sobre ela, o qual terá aberto novos olhares ao entendimento de nossa primeira Nobel de Literatura, tanto do Chile quanto do restante das Américas Ibéricas.

Published: March 2019

Introducción. La cochinilla harinosa (Hemiptera: Pseudococcidae) se conoce por su importancia a nivel comercial, puede afectar todas las etapas de desarrollo del cultivo y causar pérdidas de la cosecha. Objetivo. El objetivo de la presente revisión bibliográfica consistió en sintetizar los principales aspectos relacionados con la taxonomía, biología, daños a las plantas hospedantes, distribución geográfica e impacto de la cochinilla harinosa en las Musáceas. Desarrollo. La mayoría de los géneros tienen una amplia distribución geográfica. Pueden transportarse durante el embarque del cultivo a exportar, escapando a las regulaciones fitosanitarias, con un alto riesgo de introducción como plaga de cultivos de importancia económica de otros países. Para identificar al individuo a nivel de especie se utilizan las hembras adultas, los machos y ninfas carecen de características necesarias para su clasificación. Dentro de la familia Pseudococcidae sobresale Pseudococcus elisae (Borchsenius), como una de las primeras especies identificadas en el cultivo de Musáceas. El Servicio Fitosanitario del Estado del Ministerio de Agricultura y Ganadería de Costa Rica, declaró para finales del 2013 e inicios del 2014, emergencia fitosanitaria a causa del aumento de P. elisae, sin embargo, existen registros de hasta veinticuatro especies como vectores del virus del estriado del banano, pertenecientes a catorce géneros con distintos orígenes. El período de alimentación donde ocurre la transmisión, está relacionado con la especie y las condiciones ambientales. A la vez que inyectan toxinas, se secretan líquidos azucarados del floema de la planta, que sirven de medio para el establecimiento de hongos sobre la superficie de los órganos atacados, lo cual provoca daños fisiológicos al cultivo. Conclusión. Es de gran importancia considerar los aspectos relacionados con la taxonomía, la biología, las plantas hospedadoras y la distribución geográfica de las diferentes especies de la cochinilla harinosa para desarrollar estrategias apropiadas que controlen la propagación de la plaga.

AbstractIn order to begin to evaluate and model the suitability of high temperature ceramic composites, such as AlN:Mo, as susceptor materials for power beaming applications, the electromagnetic, thermal, and mechanical properties of the material must be known at elevated temperatures. Work reported here focuses on the development of thermal property datasets for AlN:Mo composites ranging from 0.25% to 4.0% Mo by volume. To calculate thermal conductivity of the AlN:Mo composite series, specific heat capacity, thermal diffusivity, and density data were acquired. The calculated specific heat capacity, Cp, of the set of AlN:Mo composites was, on average, found to be approximately 803 J/kgK at 100 °C and to increase to approximately 1133 J/kgK at 1000 °C, with all values to be within +/- 32 J/kgK of the average at a given temperature. These calculated specific heat capacity values matched values derived from DSC measurements to within the expected error of the measurements. Measured thermal diffusivity, α, of the set of AlN:Mo composites was, on average, found to be approximately 3.93 × 10-1 cm2/s at 100 °C and to increase to approximately 9.80 × 10-2 cm2/s at 1000 °C, with all values within +/- 1.84 × 10-2 cm2/s of the average at a given temperature. Thermal conductivity, k, for the set of AlN:Mo composites was found to be approximately 108 W/mK at 100 °C and to decrease to approximately 38 W/mK at 1000 °C, with all values within +/- 5.3 W/mK of the average at a given temperature. Data trends show that increasing Mo content correlates to lower values of of Cp, α, and k at a given temperature.

Published: March 2019

The activity of several lanthanide promoted Ceria in CO oxidation was studied. Samples were obtained by a high yield and sustainable method by urea thermal decomposition. Precursors basic carbonates, Ce1-xLnx(OH)CO3, being Ln = La (III), Sm(III), Gd(III), Pr(III) were prepared in the range of compositions 0 to 30 at.%. These precursors were annealed to moderate temperature obtain Ln-Ce mixed oxides, at 450ºC. These exhibit large surface areas up to 120 m2/g. Their catalytic performance revealed good activity towards CO oxidation (COOX) for all samples. However, a different behavior may be observed for Ln content higher than 20 at.%. By the reactor operation in differential conditions, the activation energy for COOX were obtained for all samples. The rise of activation energy as a function of Ln(III-IV) content is analyzed in the frame of phase stability and surface segregation.
Antioxidant effect of genistein on ovarian tissue morphology, oxidant and antioxidant activity in rats with induced polycystic ovary syndrome
Authors: Rajaei Samira , Alihemmati Alireza , Abedelahi Ali 
Published: March 2019

Background: Oxidative stress is the most frequent cause of female infertility disorders including polycystic ovary syndrome (PCOS). Genistein as a major component of soybean isoflavone scavenges free radicals by antioxidant activities.
Objective: The present study examines the antioxidant effects of genistein on ovarian tissue following experimental PCOS in rats.
Materials and Methods: Twenty female Wistar rat were randomly divided into the following groups (n=5 each group): (I) control group (no treatment); (II) induced PCOS (injection of estradiol valerate); (III) genistein-treated non-PCOS (received genistein); and (IV) genistein-treated PCOS groups. The weight of rats were measured and the blood samples collected and centrifuged. The oxidant and antioxidant activity of plasma and ovaries were measured. All rats were sacrificed under anesthesia, and ovaries were collected and weighted. Histological examination and follicular qualitywere assessed by staining.
Results: In histological observation, the induced PCOS rats displayed more number of atretic follicles and the follicular quality in genistein-treated rats was similar to the control groups. The plasma and ovaries malondialdehyde levels significantly increased in PCOS rats (p < 0.001), while the total antioxidant capacity levels, glutathione peroxidase, and superoxide dismutase activities significantly decreased (p < 0.001). The plasma and ovary malondialdehyde levels significantly decreased in PCOS rats that were treated with genistein (p < 0.001) and the total antioxidant capacity (p < 0.05), glutathione peroxidase, and superoxide dismutase activities significantly increased (p < 0.001).
Conclusion: Treatment with genistein preserved follicular quality by increasing antioxidant activities and scavenging oxidant levels in PCOS rats.

Corifollitropin-α compared to daily r-FSH in for patients undergoing intracytoplasmic sperm injection: Clinical trial study
Authors: Zahiri Sorouri Ziba , Pourmarzi Davoud , Safar Khah Niloufar 
Published: March 2019

Background: The current treatment regimen for ovarian stimulation in Intracytoplasmic sperm injection (ICSI) patients is daily injections of Gonadotropins. Recombinant DNA technologies have produced a new recombinant molecule that is a long-acting Follicle Stimulating Hormone (FSH), named corifollitropin alfa. A single injection of long-acting FSH can replace seven daily FSH injections during the first week of controlled ovarian stimulation (COS) and can make assisted reproduction more patients-friendly. There is limited data with different results in this area.
Objective: To compare the effectiveness of long-acting FSH vs. daily r-FSH in terms of pregnancy and safety outcomes in women undergoing ICSI cycles.
Materials and Methods: In this clinical trial study, 109 women who were the candidates for ICSI at azzahra hospital were divided in two groups. The first group received 150 units of daily Gonal-f from second or third day of menstruation. The second group received a 150IU corifollitropin alfa on the second or third day of mensuration, and the treatment continued from day eighth of stimulation with Gonal-f based on the ultrasound finding. Both the groups received GnRH antagonist from fifth day of stimulation. Two groups were compared in terms of number of dominant follicles, number of oocytes, stimulation duration, total number of embryos, number of transferred embryos, and success rate of pregnancy.
Results: No significant difference was found between the two groups in terms of stimulation duration, number of follicles, number of oocytes, total number of embryos, and number of transferred embryos. Moreover, pregnancy outcomes including chemical pregnancy rate (positive pregnancy test), clinical pregnancy rate (detection of fetal heart), the rate of ovarian hyper-stimulation syndrome, multiple-pregnancy, ectopic pregnancy, and miscarriage didn’t have a significant difference between the two groups.
Conclusion: As corifollitropin alfa was as effective as r-FSH, it could be used as an alternative to ovulation stimulation method in patients undergoing ICSI.

Authors: Shakeri Mahboobeh , Jafarirad Sima 
Published: March 2019

Background: Vitamin D deficiency is a common nutritional concern and leads to several problems among some population groups.
Objective: The aim of the current study was to evaluate the relationship between maternal vitamin D status and gestational weight gain, maternal biochemical parameters, mode of delivery, and infants’ growth indices at birth.
Materials and Methods: A longitudinal study between March and June 2017 was carried on 82 mothers in Ahvaz. Blood samples of each mother were obtained at the mean of the third trimester to assay lipid indices (total cholesterol, triglycerides, lowdensity lipoprotein, and high-density lipoprotein cholesterol), fasting blood sugar, and 25-hydroxy vitamin D. Anthropometric assessment of newborns was recorded from neonatal health card at birth.
Results: Mean maternal 25-hydroxy vitamin D level was 22.52 nmol/L; 7.33% of mothers had vitamin D deficiency, 76.6% had vitamin D insufficiency, and 15.9% were normal. The mean neonate birth weight, length, and head circumference of mothers who were on the third tercile of 25-hydroxy vitamin D serum level was significantly higher than those in the first tercile (p < 0.001, p = 0.004 and p < 0.001, respectively). Maternal vitamin D serum level had an adverse relationship with fasting blood sugar.
Conclusion: Low levels of serum vitamin D may cause adverse pregnancy outcomesand delivery of infants with insufficient growth at birth.

AIMSTo quantify the preferences and preparations for support during labor and the first hours after childbirth of pregnant women and the specific preference for continuous support. To investigate the association with parity and the intended place of birth.DESIGNCross-sectional survey.METHODSTwelve midwifery practices in the northern Netherlands recruited pregnant women.Measurements of the structured questionnaire were preparation for childbirth and preference for support (timing, including continuous support, provider, and type of support)RESULTSTwo hundred and five of the 247 eligible women participated. Nulliparae, significantly more often than multiparae, aimed to prepare themselves by attending prenatal classes (63% vs. 21%) and by creating a birth plan (59% vs. 40%). Women preferred to receive various types of support during childbirth from their partner (100%), midwife (95%), Maternity Care Assistant (29%), and nurse (15%). The women preferred the midwife to be present from the moment the midwife (48%) or the woman herself (22%) indicated a need for the midwife. Among the participants, 10% of the women preferred continuous support from 4 cm dilation.CONCLUSIONWe consider the best approach to continuous support to be that it should be available on request rather than either not being available or being the standard care.
Development of load duration curve system in data-scarce watersheds based on a distributed hydrological model

Published: March 2019

AbstractMany developing countries and regions are currently facing serious water environmental problems, especially the lack of monitoring systems for medium- to small-sized watersheds. The load duration curve (LDC) is an effective method to identify polluted waterbodies and clarify the point sources or non-point sources of pollutants. However, it is a large challenge to establish the LDC in small river basins due to the lack of available observed runoff data. In addition, the LDC cannot yet spatially trace the specific sources of the pollutants. To overcome the limitations of LDC, this study develops a LDC based on a distributed hydrological model of the Soil and Water Assessment Tool (SWAT). First, the SWAT model is used to generate the runoff data. Then, for the control and management of over-loaded polluted water, the spatial distribution and transportation of original sources of point and non-point pollutants are ascertained with the aid of the SWAT model. The development procedures of LDC proposed in this study are applied to the Jian-jiang River basin, a tributary of the Yangtze River, in Duyun city of Guizhou province. The results indicate the effectiveness of the method, which is applicable for water environmental management in data-scarce river basins.
Nutrient recovery and microbial diversity in human urine fed microbial fuel cell
Authors: Sharma Priya , Mutnuri Srikanth 
Published: March 2019

Abstract
Presence of urine in municipal wastewater is a major problem faced by wastewater treatment plants. The adverse effects are noticeable as crystallization in equipment and pipelines due to high concentration of nitrogen and phosphorus. Therefore, improved technologies are required that can treat urine separately at the source of their origin and then discharge it in the main wastewater stream. In this study, the performance of the microbial fuel cell (MFC) was evaluated with mixed consortia and isolated pure cultures (Firmicutes and Proteobacter species) from biofilm for electricity generation and nutrient recovery. Microbes utilize less than 10% of total phosphorus for their growth, while 90% is recovered as struvite. The amount of struvite recovered was similar for pure and mixed culture (12 ± 5 g/L). The microbial characterization also shows that not all the biofilm-forming bacterial isolates are very much efficient in power generation and, hence, they can be further exploited to study their individual role in operating MFC. The different organic loading rates experiment shows that the performance of MFC in terms of power generation is the same for undiluted and five times diluted urine while the recovery of nutrients is better with undiluted urine, implying its direct use of urine in operating fuel cell.

Authors: Ozmen Ozlem , Topsakal Senay 
Published: March 2019

Objective:
The aim of this study was to examine pancreatic pathology and the prophylactic
effects of pregabalin in lipopolysaccharide (LPS) induced sepsis model in aged rats.

Methods:
Twenty-four female, one-year-old, Wistar Albino rats were assigned to three groups; Group I
(control), Group II (study group: 5mg/kg LPS intraperitoneal, single dose) and Group III(treatment
group: 5mg/kg LPS+30 mg/kg oral pregabalin one hour before LPS). Animals were sacrificed by exsanguination
6 hours after LPS administration. Blood and pancreatic tissue samples were collected for
biochemical, pathological, and immunohistochemical analyses.

Results:
LPS caused increases in serum amylase and lipase level but led to a reduction in glucose levels.
Following histopathological analysis, numerous neutrophil leucocyte infiltrations were observed in vessels
and pancreatic tissues. Increased caspase-3 expression was observed in both the endocrine and exocrine
pancreas in the LPS group. Similarly, IL-6, caspase-3 (Cas-3), inducible nitric oxide synthase
(iNOS), granulocyte colony-stimulating factor (G-CSF) and serum amyloid-A (SAA) expressions were
increased by LPS. Pregabalin improved biochemical, histopathological, and immunohistochemical findings.

Conclusion:
This study showed that LPS causes pathological findings in the pancreas, but pregabalin
has ameliorative effects in aged rats with sepsis. Cas-3, IL-6, iNOS, G-CSF, and SAA all play pivotal
roles in the pathogenesis of LPS-induced pancreatic damage.

Background and Objective:Spasticity (most common disability in upper motor neuron syndrome or UMNS) caused an inability of patients’ to perform daily activities and a decrease inquality of life. One of the promising methods nowadays, but still not widely used in everyday practice, for spasticity reduction is extracorporeal shock wave. The aim of this study was to evaluate the objective clinical effects of combined treatment botulinum toxin type A and radial Extracorporeal Shock Wave Therapy in spasticity post stroke.Methods:We considered 30 subjects (14 female and 16 male) with post stroke spasticity of Biceps Brachii, Superficial Flexor Digitorum, Gastrocnemius Medialis and Lateralis and we divided patients into two groups (group A received botulinum toxin injection and physiotherapy while group B received botulinum toxin injection, rESWT and physiotherapy). Assessments were performed before treatment (t0), after 1 (t1), 2 (t2) e 3 (t3) months using Modified Ahworth Scale, Visual Analogical Scale for pain and MyotonPro® device (to assessed myometric evaluation of muscles tone and stiffness).Results:Visual Analogical Scale, Modified Ahworth Scale, muscles tone and stiffness statistically decreased until t3 in the group A and in the group B, but the differences between the two groups were significant at the t1 only.Conclusion:Radial Extracorporeal Shock Wave Therapy could be an effective physical treatment aimed at the reduction of upper and lower limbs spasticity and could lead to the improvement of trophic conditions of the spastic muscles in post-stroke.
