The effect of cross-cutting partisan debates on political decision-making
Authors: Sheagley Geoffrey
Published: August 2017

Party identification provides citizens with an anchor from which they derive many of their political attitudes and issue preferences. But what happens when people encounter political debates that place their partisan identities and policy attitudes into conflict with one another? This article draws on an original experiment designed to study the effect of debates that cut across people’s partisan identities and policy attitudes. The results show that cross-cutting debates make people less likely to engage in selective exposure, more likely to feel ambivalent toward their political party, and less likely to rely on party cues when rendering a judgment.
Theorizing materialism through the Institutional Analysis and Development framework
Authors: Kilbourne William E. , Dorsch Michael J. , Thyroff Anastasia
Published: August 2017

Materialism in Western societies has been examined at both individual and cultural levels. However, the underlying institutions that engender and perpetuate materialism as an orientation toward consumption are left unexamined. Therefore, the overall purpose of this study is to explore the relationship between institutions constituting the dominant social paradigm (DSP) (deep-rooted belief structures and practices) of societies and materialism. The model proposed to carry this out is the Institutional Analysis and Development framework. This article contributes to marketing theory by developing a conceptual model that explains and offers transformative implications pertaining to the relationship between materialism and the institutional elements of the DSP of Western industrial societies.
A single institution experience for the management of recurrent pleural effusions with tunneled pleural catheter and its evolution
Authors: Raman Tuhina , Meena Nikhil
Published: August 2017

Background:

Indwelling tunneled pleural catheters (TPCs) are increasingly being used to treat recurrent pleural effusions. There is also an increased interest in early pleurodesis in order to prevent infectious complications. We studied the time to removal and other outcomes for all the TPCs placed at our institution.

Methods:

After institutional review board approval, records of patients who had had a TPC placed between July 2009 and June 2016 were reviewed; the catheters were placed in an endoscopy suite or during pleuroscopy with or without a sclerosant. The catheters were drained daily or less frequently and were removed after three drainages of less than 50 ml.

Results:

During the study period 193 TPCs were placed. Of these 45 (23%) were placed for benign diseases. The commonest malignancy was lung cancer 70 (36%). Drainage 2–3 times a week without a sclerosant ( n = 100) lead to pleurodesis at 57 ± 78 days, while daily drainage after TPC + pleuroscopy + talc ( n = 41) achieved the same result in 14 ± 8 days ( p < 0.001). TPC + talc + daily protocol achieved pleurodesis in 19 ± 7 days, TPC + rapid protocol achieved the same result in 28 ± 19 days ( p = 0.013). The TPCs + sclerosant had an odds ratio of 6.01 (95% confidence interval: 2.1–17.2) of having a complication versus TPC without sclerosant.

Conclusions:

It is clear that TPCs when placed with a sclerosant had a significantly shorter dwell time; However, they were associated with higher odds of complications. One must be aware of these possibilities when offering what is essentially a palliative therapy.
Current immunotherapeutic strategies in hepatocellular carcinoma: recent advances and future directions
Authors: Kim Hwi Young , Park Joong-Won
Published: August 2017

Hepatocellular carcinoma (HCC) is a common and serious health problem with high mortality. Treatment for HCC remains largely unsatisfactory owing to its high recurrence rates and frequent accompanying cirrhosis. In addition, the unique immune environment of the liver promotes tolerance, which, in conjunction with immune evasion by the disease, makes HCC a less promising target for conventional immunotherapy. However, recent advances in the immunotherapy have led to novel approaches to overcome these obstacles by manipulating and enhancing tumor-specific immune responses against HCC by using various modalities, such as cancer vaccines and immune checkpoint blockade. These treatments have shown both safety and promising outcomes in patients with HCC of various etiologies and tumor stages. Furthermore, combined strategies have been assessed to achieve optimal outcomes, by using immunotherapies with or without conventional treatments. This review briefly covers the background, recent advances, current issues, and future perspectives on immunotherapy in the field of HCC treatment.
Therapeutic drug monitoring of CT-P13: a comparison of four different immunoassays
Authors: Afonso Joana , de Sousa Helena Tavares , Rosa Isadora , Carvalho João , Dias Cláudia Camila , Magro Fernando
Published: August 2017

Background:

The commercialization of CT-P13, an infliximab (IFX) biosimilar, has the potential to decrease health-related costs and enhance access to biological therapies. This study aimed to address the accuracy and inter-assay agreement of the CT-P13 quantification using four different assays initially developed to assess IFX.

Methods:

The four different methods, one in-house method and three commercially available kits, were used to quantify exogenously-spiked samples and the sera from 185 inflammatory bowel disease (IBD) patients on CT-P13 therapy.

Results:

The quantification of the spiked samples unveiled a consistent and accurate behaviour of three of the tested methods, with average percentage recoveries of 90%, 102% and 109%. Results from the clinical samples demonstrated that these three assays were also highly correlated, both concerning Spearman’s rank coefficients (range 0.890–0.947) and intraclass correlation coefficients (range 0.907–0.935). There were a few systematic deviations among them, but their impact in the clinical stratification of the patients using different cut-offs was minimal, particularly when these cut-offs were in the 3–4 µg/ml range, for which the strength of agreement (as assessed by the Kappa statistics that ranged from 0.732 to 0.902) was substantial to almost perfect.

Conclusions:

Our results indicate that three of the tested IFX quantification methods can be used to accurately quantify CT-P13 without any adjustments.
The Eye Pupil’s Response to Static and Dynamic Illusions of Luminosity and Darkness
Authors: Zavagno Daniele , Tommasi Luca , Laeng Bruno
Published: August 2017

Pupil diameters were recorded with an eye-tracker while participants observed cruciform patterns of gray-scale gradients that evoked illusions of enhanced brightness ( glare) or of enhanced darkness. The illusions were either presented as static images or as dynamic animations which initially appeared as a pattern of filled squares that—in a few seconds—gradually changed into gradients until the patterns were identical to the static ones. Gradients could either converge toward the center, resulting in a central region of enhanced, illusory, brightness or darkness, or oriented toward each side of the screen, resulting in the perception of a peripheral ring of illusory brightness or darkness. It was found that pupil responses to these illusions matched both the direction and intensity of perceived changes in light: Glare stimuli resulted in pupil constrictions, and darkness stimuli evoked dilations of the pupils. A second experiment found that gradients of brightness were most effective in constricting the pupils than isoluminant step-luminance, local, variations in luminance. This set of findings suggest that the eye strategically adjusts to reflect in a predictive manner, given that these brightness illusions only suggest a change in luminance when none has occurred, the content within brightness maps of the visual scene.
Do Biology Students Really Hate Math? Empirical Insights into Undergraduate Life Science Majors’ Emotions about Mathematics
Authors: Wachsmuth Lucas P. , Runyon Christopher R. , Drake John M. , Dolan Erin L.
Published: August 2017

Undergraduate life science majors are reputed to have negative emotions toward mathematics, yet little empirical evidence supports this. We sought to compare emotions of majors in the life sciences versus other natural sciences and math. We adapted the Attitudes toward the Subject of Chemistry Inventory to create an Attitudes toward the Subject of Mathematics Inventory (ASMI). We collected data from 359 science and math majors at two research universities and conducted a series of statistical tests that indicated that four AMSI items comprised a reasonable measure of students’ emotional satisfaction with math. We then compared life science and non–life science majors and found that major had a small to moderate relationship with students’ responses. Gender also had a small relationship with students’ responses, while students’ race, ethnicity, and year in school had no observable relationship. Using latent profile analysis, we identified three groups—students who were emotionally satisfied with math, emotionally dissatisfied with math, and neutral. These results and the emotional satisfaction with math scale should be useful for identifying differences in other undergraduate populations, determining the malleability of undergraduates’ emotional satisfaction with math, and testing effects of interventions aimed at improving life science majors’ attitudes toward math.
Introduction
Authors: Verne Julia , Verne Markus
Published: August 2017

Over the last thirty years, the Indian Ocean has increasingly been conceptualized as a maritime spatial unit created by translocal relations and processes of exchange. Only recently, however, these relations are being examined from a “bottom-up” perspective, e.g., with a focus on the ways in which those who live at, with, and from the Indian Ocean experience this translocal space and render it meaningful. As a result, an understanding of the Indian Ocean emerges in which its size, shape, and range change with the topics at stake. Taking the Swahili coast as a case in point, Julia Verne and Markus Verne note, the special section “The Indian Ocean as Aesthetic Space” wants to contribute to such an understanding by exploring the Indian Ocean as an aesthetically constituted space. Aesthetic practices and experiences are crucial, they argue, for imaginations of the Indian Ocean and, thus, also for how the Indian Ocean affects social and cultural processes. These aesthetic imaginations, however, reflect far more than the actual empirical processes of cultural or material exchange. Therefore, instead of being deduced from historical fact, they need to be studied in their own right.
Diplomacy and Ethnology between Empire and Nation
Authors: Opondo Sam Okoth
Published: August 2017

Opondo's essay focuses on the theoretical stakes of the debates in Frederick Cooper's Citizenship between Empire and Nation and looks at how ethnological reason haunts the debates over how to govern different people differently while at the same time articulating the language of citizenship. The essay also engages a corollary to Cooper's elaborate treatment of the empirics of empire and the related empire of empirics by looking at the book's contribution to critical diplomatic theory.
Adipose tissue, metabolic and inflammatory responses to stroke are altered in obese mice

Published: August 2017

Obesity is an independent risk factor for stroke, though several clinical studies have reported that obesity improves stroke outcome. Obesity is hypothesised to aid recovery by protecting against post-stroke catabolism. We therefore assessed whether obese mice had an altered metabolic and inflammatory response to stroke. Obese ob/ob mice underwent 20 min middle cerebral artery occlusion and 24 h reperfusion. Lipid metabolism and expression of inflammatory cytokines were assessed in the plasma, liver and adipose tissue. The obese-specific metabolic response to stroke was assessed in plasma using non-targeted UPLC-MS metabolomics coupled with univariate and multivariate analysis. Obesity had no effect on the extent of weight loss 24 h after stroke but affected the metabolic and inflammatory responses to stroke, predominantly affecting lipid metabolism. Specifically, obese mice had increases in plasma free fatty acids and expression of adipose lipolytic enzymes. Metabolomics identified several classes of metabolites affected by stroke in obese mice, including fatty acids and membrane lipids (glycerophospholipids, lysophospholipids and sphingolipids). Obesity also featured increases in inflammatory cytokines in the plasma and adipose tissue. Overall these results demonstrate that obesity affected the acute metabolic and inflammatory response to stroke and suggest a potential role for adipose tissue in this effect. These findings could have implications for longer-term recovery and also further highlight the importance of considering comorbidities in preclinical stroke research, especially when identifying biomarkers for stroke. However, further work is required to assess whether these changes translate into long-term effects on recovery.
Assessment of the State of Surface Waters Using Reusable Solid-Phase Polymer Indicators in the Field Environment

Published: August 2017

As a result of many years of economic activity, a large number of anthropogenic factors arise that change the dynamics of the transformation of the quality of surface waters. The growing deterioration in their quality is due to the long-term impact of various pollution sources (industrial production, road transport, agriculture, technogenic deposits, heat power facilities, oil and gas pipelines, etc.). However, a wide range of heavy metals enters the surface waters, along with the increase in macrocomponents during technogenic dispersion of toxicants. This requires a systemic evaluation of surface water. Modern methods are based on the use of devices that have been used up, recyclable or disposable paper sets with a perceptible range of error in the determination. In this paper, for the rapid analysis of the state of surface waters on the presence of heavy metals, solid-state polymer indicators were used. The possibility of non-laboratory application in practice of color solid-state polymeric indicators of reusable use, preserving shades of color for two years or more, is shown. Characteristics of indicators were studied in laboratory conditions and tested in the study of lake and river water in several Russian regions (Lake Valday, Polomet River, Onego Lake, etc.). The developed methodology is based on the testimony of four parameters: temperature, pH; The changed color of the polymer indicator, followed by a comparison of pH and color with the indicator’s reference scale; Of the total index of water pollution by heavy metals. Comparing the results with the indicators of the working scale, in which all four indicators are included, the estimation of the level of contamination by heavy metals of surface waters with high accuracy is carried out. In addition, this method makes it possible to establish the significant role of bottom sediments in the formation of surface water quality. The results of the carried out research make it possible to increase the number of observations in time and space and to obtain a significant amount of information base on the ecological state of water bodies during their monitoring.
Dynamic Programming Decomposition for Choice-Based Revenue Management with Flexible Products
Authors: Koch Sebastian , Gönsch Jochen , Steinhardt Claudius
Published: August 2017

We reconsider the stochastic dynamic program of revenue management with flexible products and customer choice behavior as proposed by Gallego et al. [Gallego G, Iyengar G, Phillips RL, Dubey A (2004) Managing flexible products on a network. Working paper, Columbia University, New York]. In the scientific literature on revenue management, as well as in practice, the prevailing strategy to operationalize dynamic programs is to decompose the network by resources and solve the resulting one-dimensional problems. However, to date, these dynamic programming decomposition approaches have not been applicable to problems with flexible products, because sold flexible products must be included in the dynamic program’s state space and do not correspond directly to resources. In this paper, we contribute to the existing research by presenting a general approach to operationalizing revenue management with flexible products and customer choice in a dynamic programming environment. In particular, we reformulate the original dynamic program by means of Fourier–Motzkin elimination to obtain an equivalent dynamic program with a standard resource-based state space. This reformulation allows the application of dynamic programming decomposition approaches. Numerical experiments show that the new approach has a superior revenue performance and that its average revenues are close to the upper bound on the optimal expected revenue from the choice-based deterministic linear program. Moreover, our reformulation improves the revenues by up to 8% compared to an extended variant of a standard choice-based approach that immediately assigns flexible products after their sale.

MODELAMIENTO DE UN ALGORITMO PARA LA ASIGNACION DE LONGITUDES DE ONDA EN UN MULTIPLEXOR DWDM MINIMIZANDO EL PROCESO DE MEZCLADO DE LA CUARTA ONDA FWM (FOUR WAVE MIXING)
Authors: Mojica Cáceres Jorge Arturo
Published: August 2017

Uno de los medios de transmisión de alta velocidad más utilizados en nuestro entorno es la fibra óptica especificada en el estándar ITU-T G.625; sin embargo, su despliegue y utilización plantea en la actualidad varios desafíos a resolver debido a su característica de no linealidad, dentro de los cuales se encuentra el relacionado con la disminución del nivel de interferencia. Con el ánimo de brindar un aporte en la solución de esta problemática se propone modelar el comportamiento no lineal de FWM cuando se implementan sistemas de multiplexación de longitudes de onda por un único hilo de fibra óptica a fin de poder estimar las características fundamentales que rige esta tecnología y poder plantear un algoritmo que sea capaz de reducir la interferencia no lineal de cuarta onda (FWM). Como conclusión principal se encontró que el modelo propuesto reduce la interferencia no lineal FWM, lo que permite un aumento en la asignación de canales DWDM aumentando el ancho de banda establecido en cada enlace óptico.

The  presence  of  air  pollution  in  ambient  air  is  closely  related  to  the incidence  of  adverse reactions affecting human health. One of harmful pollutants and potentially major cause health problems is sulfur dioxide (SO 2 ). The number of vehicles that are passing and queuing on the crossroads  because  of  traffic light can  affect  the  concentration  of  SO 2 .  Besides,  in  these locations  there  are a lot of road users  which  are  potentially  exposed  by  contaminants, so information about the concentration of SO 2  is important to know. This study aimed to investigate the  impact  of  meteorological  factors  and  the  number  of vehicles  on  SO 2   concentrations. Impinger was used for air sampling, and pararosaniline method was used for determining SO 2  concentration. Sampling and calculation  of the number of passing vehicles were performed 3 times ie in the morning, afternoon and evening. Based on the results of the study, the highest concentrations of SO 2  were on the range of 15-21 mg/Nm3.
Methodology of synchronization among strategy and operation. A standards-based modeling approach
Authors: COLLAZOS VICTOR EDWIN , DUARTE AMAYA HELGA
Published: August 2017

Enterprise Architecture (EA) has gained importance in recent years, mainly for its concept of “alignment” between the strategic and operational levels of organizations. Such alignment occurs when Information Technology (IT) is applied correctly and timely, working in synergy and harmony with strategy and the operation to achieve mutually their own goals and satisfy the organizational needs.Both the strategic and operational levels have standards that help model elements necessary to obtain desired results. In this sense, BMM and BPMN were selected because both have the support of OMG and they are fairly well known for modelling the strategic level and operational level, respectively. In addition, i* modeling goal can be used for reducing the gap between these two standards. This proposal may help both the high-level design of the information system and to the appropriate identification of the business processes that will support it.This paper presents a methodology for aligning strategy and the operation based on standards and heuristics. We have made a classification for elements of the models and, for some specific cases, an extension of the heuristics associated between them. This allows us to propose methodology, which uses above-mentioned standards and combines mappings, transformations and actions to be considered in the alignment process.
Elasto-plastic model to determine the maximum force for shaft straightening process
Authors: Galvis Salazar Juan Camilo , Maury Ramírez Heriberto Enrique , Hernández Donado Roque Julio
Published: August 2017

This paper shows the development of a mathematical model based on elasto-plastic behavior of materials in order to determine the bending moment and the maximum straightening force required to repair a bent shaft. The importance of this work is because many machines use shafts to transmit power and movement, and these elements can suffer permanent deflections during operation cycles. An appropriate reparation process can increase the life of these elements significantly. Knowing the mechanics for a straightening process is essential for design, processes and maintenance engineers in charge of systems that use these elements (shafts).

Published: August 2017

Knowledge regarding the characteristics of soils in Bogotá basin has been possible to get through previous microzonation studies. However, there is still insufficient knowledge of the crustal velocity structure of the region. Bogotá is located in a region prone to a significant seismic hazard. Historically, the city has been affected by strong earthquakes, reaching moment magnitudes greater than or equal to 7. Furthermore, the city was built on a lacustrine basin, with soft soils of considerable depth that may strongly amplify the ground motion during an earthquake. In this article, we describe the development of a first crustal structure and material properties model for the region of Bogotá, Colombia, covering an area of about 130 km by 102 km. This effort aims at constructing a realistic 3D seismic velocity model using geological and geotechnical information from several sources. Major geological units have been identified and mapped into the model. The Inverse Distance Weighted (IDW) interpolation was used to create continuous surfaces delimiting the geological units. Seismic-wave properties are assigned to any point in the domain using a location-based approach. We expect this model to be useful for a wide range of applications, including dynamic ground motion simulations and fault system modeling.
Az információfeldolgozás korai szakaszának lassulása időskorban: Visszaható maszkolás és integráció

Az időskori érzékszervi változásokról és az információfeldolgozás figyelmi szakaszairól rendelkezésre álló jelentős ismeretek mellett viszonylag ritkábban kutatott terület az észlelés korai műveleteinek vizsgálata. Két kísérletben vizsgáltuk e szakaszokat fiatal (19–26 év) és idős (64–75 év) csoportokban. A visszaható maszkolási kísérletben érzelmeket kifejező sematikus arcokat követett értelmetlen mintázatú maszk. A bemutatást követően kétválasztásos helyzetben kellett dönteni arról, hogy melyik érzelmet mutatta az arc. Az arc-maszk időközt lépcsőzetes módszerrel változtattuk a ~80%-os kritériumig. Idős személyeknél a kritikus időtartam (amíg a maszk hatékony volt), lényegesen hosszabb volt, mint fiataloknál, azaz a fiatalabb csoportban a két inger elkülönült feldolgozásához rövidebb idő kellett. Az integrációs kísérletben három betű jelent meg egymás mellett két részletben úgy, hogy a betűk ebből a két részletből állhattak össze. A résztvevők feladata az volt, hogy döntsék el, a három betű értelmes szót alkotott, vagy sem. A változó a két részlet bemutatása közötti időköz volt, melyet ismét lépcsőzetes módszerrel változtattunk. A két életkori csoport között nem találtunk megbízható különbséget, azaz a töredék első részének reprezentációjának fennállása nem volt hosszabb egyik csoportnál sem. A maszkolási eredmények megfelelnek a más módszerekkel mért adatoknak, a ritkábban alkalmazott integrációs módszer eredményei viszont arra utalnak, hogy a mért életkori változások iránya jelentősen függ az alkalmazott paradigmától.
Of Famines and Females
Authors: Sengupta Saswati , Purkayastha Sharmila
Published: August 2017

Laksmi Bratakathas in Bengal are religious narratives of the eponymous Hindu goddess who presides over prosperity symbolized through an abundance of rice. The reciting of these Laksmi Bratakathas is a sacral duty of the women of the Bhadralok, which remains a popular practice even today. The period of rise and proliferation of these specific narratives, from the eighteenth century onwards, coincides with catastrophic famines with which imperialism in Bengal starts and ends and which provide the historical motivations for requesting the intervention of the goddess of plenty. But there is a deliberate mystification of hunger as Laksmi displaces the problem of famine onto the axes of vice and virtue, which are specifically located in the transgressive figure of the 'New Woman'. Since this is also the period which ushers in a new construction of gender relations, the displacement in these Bratakathas is of critical importance. The article examines the ideological framing of hunger by locating the matrices of the colliding and colluding histories of colonialism, class and gender.

Published: August 2017

The guiding principles for the prevention of Infective Endocarditis (IE) following dental procedures have been a debatable topic for a long time now. Evidently this has led to numerous amounts of research and consequently dental practitioners from across the world follow different prophylactic treatment regimens. At present, there are a few regimens that various health authorities have endorsed in their respective countries. There is a lack of substantial data in order to determine which regimen is better over the other, and unfortunately, that places the practitioner in a difficult situation to decide the best for his patient.

Published: August 2017

The purpose of this investigation is to identify the key determinants of project success within the construction industry of Ghana using Wide Horizon Ghana limited as a case study. A self-administered questionnaire is used to gather primary data from relevant stakeholders within the scope of the study. The results showed that project manager’s influence and leadership style, project team members’ coordination, availability of resources and funds, organizational success and client’s satisfaction as well as the completion of projects on time were the main project success factors in the industry. Negative influences from stakeholders among others were seen as factors that contribute to project failure. It is recommended that Construction project managers or leaders should pay more attention to these success factors to ensure project success or minimize the rate of project failure within Ghana and the West African sub-region.

La investigación tuvo como objetivo evaluar el efecto de tratamientos físicos y químicos sobre la germinación de la semilla de Bactris guineensis bajo condiciones controladas. Asimismo, se estudió el efecto del tiempo de almacenamiento. Se realizaron tres experimentos: 1) se evaluó el efecto de dos contenidos de humedad de almacenamiento (17% y 19%), cuatro tiempos de almacenamiento (cero, dos, cuatro y ocho meses) y tres tiempos de exposición en calor seco a 40 °C (cero, 15 y 30 días) sobre el porcentaje de germinación y la viabilidad de semillas. 2) Se evaluó el efecto del ácido giberélico (AG3) en dos concentraciones (200 y 400 ppm) y cianamida hidrogenada (CH2N2) sobre la superación del reposo o latencia. 3) También se evaluó el efecto del tiempo de fermentación durante cero, 7,14 y 21 días en combinación con la inmersión de las semillas en agua a punto de ebullición durante 0, 30, 75, 120 y 165 segundos. Se determinó que la viabilidad de las semillas se reduce significativamente conforme aumenta el tiempo de almacenamiento y con el mayor tiempo de exposición (30 días) a calor seco. Además, la viabilidad de la semilla se conservó mejor cuando la humedad de almacenamiento fue de 17%. El uso de ácido giberélico (AG3) no aumentó la germinación y no afectó la viabilidad de las semillas. Por el contrario, la inmersión en cianamida hidrogenada (CH2N2) al 2% por 24 horas no estimuló la germinación, pero no afectó la viabilidad durante el almacenamiento, mientras que la inmersión por 48 horas causó la muerte del 100% de las semillas después de cuatro meses de almacenamiento. En conclusión, la eliminación del opérculo facilitó la germinación de las semillas (42% en semilla fermentada por siete días).

Se presenta en detalle el desarrollo de la interpolación tridimensional para campos escalares, que consiste en generar información en cualquier punto del espacio, sobre alguna variable dependiente de las tres coordenadas cartesianas, en algún volumen definido. Esto a partir de un conjunto discreto de datos que representan el valor de la variable dependiente en puntos específicos del espacio.
Se desarrolla un método de interpolación tridimensional basado en obtener las coordenadas de todos los vecinos del punto de interés. Para luego asignar un peso relativo a cada uno de estos puntos, en función de la proximidad con el lugar donde se busca un nuevo valor de la variable dependiente. Este procedimiento se presenta en forma de diagrama de flujo, para que pueda ser desarrollado en cualquier lenguaje de programación.
El método propuesto es implementado en un código en software comercial y a la vez es validado al confrontar sus resultados con los que genera una función propia del software Matlab. Dicha función es detallada a profundidad para facilitar a cualquier usuario su utilización, estableciendo además las limitaciones y diferencias entre el uso de esta función y la implementación del método propuesto en un código computacional.
Se encuentra que el método propuesto es altamente confiable y que a su vez permite, eventualmente, adaptarse a condiciones donde la distribución de información en el espacio sea irregular o no se disponga de algún dato dentro de una matriz estructurada de mediciones.

La guayaba taiwanesa fue introducida en Costa Rica en 1978 y desde entonces ha sido ampliamente estudiada por sus propiedades medicinales y nutricionales. Parte de los estudios de los que ha sido foco en diferentes países, es en pruebas como agente anticancerígeno debido a su alto contenido de antioxidantes. En este trabajo se evaluó la citotoxicidad de extractos de pulpa y cáscara de guayaba en dos líneas celulares cancerígenas (pulmón NCI-H460, ATTC y adenocarcinoma colorectal humano SW480, ATTC). También se realizaron inmunotinciones con el fin de aproximar el tipo de muerte celular. Las células fueron tratadas a concentraciones crecientes desde 250 hasta 450 μg/mL con ambos tipos de extracto, durante 24, 48 y 72 horas. Las células utilizadas para las inmunotinciones fueron expuestas durante 72 horas con la concentración establecida como IC50. Se determinó que el extracto de cáscara produjo la mayor citotoxicidad en las células de cáncer de colón obteniéndose una IC50 de 337 μg/mL. Uno de los tipos de muerte que puede estar siendo inducido por el extracto fue por apoptosis, lo cual se determinó al observar la morfología de las células. Los análisis estadísticos demostraron que no se tiene un comportamiento dosis dependiente y que el factor tiempo de exposición al extracto es un factor crítico en la citotoxicidad.

Se realizó un estudio retrospectivo de las historias clínicas de dermopatías diagnosticadas en burros de trabajo, a través del Servicio Médico Ambulatorio de Grandes Animales de la Facultad de Medicina Veterinaria de la Universidad de Córdoba, desde enero de 2008 hasta diciembre de 2015. El objetivo fue determinar la frecuencia de las enfermedades cutáneas que ocurren en burros (Equus asinus). Fueron atendidos 238 casos clínicos de dermopatías, pero las más frecuentemente diagnosticadas en orden descendente fueron: las heridas traumáticas (26,4 %), ectoparasitismo por garrapatas (19,7 %), dermatofitosis (16,3 %), sarcoide (8,9 %), habronemosis (7,1 %), pitiosis (6,3 %), sarna (5,4 %), miasis (4,6 %), abscesos (2,9 %), dermatofilosis (1,7 %), papilomatosis (0,4 %), melanoma (0,4 %), fotosensibilización (0,4 %) y quemaduras (0,4 %). El grupo etario más afectado fue el de 5 a 10 años (60,3 %), seguido de los menores de 5 años (20,8 %) y los mayores de 10 años (19,2 %). Las principales enfermedades de la piel diagnosticadas en burros fueron heridas traumáticas, ectoparasitismo por garrapatas y dermatofitosis. Este trabajo es un aporte significativo sobre el estado epidemiológico de las diferentes dermopatías, con su respectiva importancia en el manejo y control.

Aim: Evaluate the masticatory performance in patients with different clinical situations: patients with natural dentition without restorative and/or orthodontic intervention (Group CG) and patients with restorations and/or orthodontic intervention (Group TG). Subjects received instruction before the experiment, related to masticatory movements. Methods: Three capsules containing the granules were delivered separately to chew for 20 seconds each, controlled by the examiner. One capsule was chewed for 20 seconds only on the left side; the second capsule was chewed for 20 seconds only on the right side; and the third capsule was chewed for 20 seconds to simulate each patient’s mastication. The mean data and standard deviation of masticatory function of each patient was calculated. Results: The results obtained in this study showed that there were no statistically significant differences (P < 0.05) between both tested groups (0.0320 ± 0.00716, 0.0436 ± 0.00974). Conclusions: Patients who were submitted to orthodontic and/or restorative procedures, with balanced occlusion could be used as a control group, making easier the patient recruitment. Clinicians and researchers on masticatory performance evaluation could apply the colorimetric method. The colorimetric method was a standardize method, effective and easy to execute.
