Afectividad y reciprocidad: aproximación a la obra de Dominique Temple
Authors: Martínez Gutiérrez Moisés
Published: November 2017

The topic of human coexistence is exposed by Temple from triadic affectivity, a state of freedom of consciousness which is experienced between one and another. Triadic affectivity is a horizon that opens to infinity and does it as a process: the process of the coming about of modes of triadic affectivity. These modes of triadic affectivity are become into values which reinforce the social tie. The triadic affectivity is explained dialectically in this work which aims to study in depth its origin.

Authors: Awan Naseer Ahmad , Mir Irfan Nazir , Wani Hila Ahmad , Ahmad Mir Mujtaba
Published: November 2017

Background: Anal fissures are associated with spasm of the internal anal sphincter and pain. In present study we compared the efficacy of local application of 0.5% minoxidil and 2% diltiazem in symptomatic relief and healing of anal fissures.Methods: In this prospective, randomized, double blind study, a total of 100 patients with anal fissure were recruited, (50 patients in each group). Patients in group A received local applications of ointments containing 0.5% minoxidil, while patients in group B received topical 2% Diltiazem. Healing of anal fissure and symptomatic relief were observed and analyzed.Results: Rates of complete healing of fissure were similar in the two groups (minoxidil 27/50, diltiazem 29/50). Mean (SD) time taken for complete healing was significantly shorter with minoxidil (3.1 weeks as compared to diltiazem (4 weeks). Rates of pain relief were similar in the two groups. Stoppage of bleeding occurred more often with use of minoxidil than with diltiazem. No patient had systemic or local side effects.Conclusions: Treatment with minoxidil helps in faster healing of anal fissures and provides similar symptomatic relief as that of diltiazem.

Background: The purpose the study was to assess the incidence of Colostomy prolapse with sigmoid loop colostomies performed through rectus muscle splitting Incision.Methods: Colostomy prolapse may present serious problems for patient care and stoma function6. Sigmoid loop colostomy was done for babies with High anorectal malformation (HARM) and Hirschsprung’s disease (HD) from Jan2012 to Dec2014 in two referral hospitals. All colostomies were sigmoid loop colostomies and done by a single surgeon through rectus muscle splitting incision. All patients were followed up for colostomy prolapse for at least 6 months.Results: A total of 110 babies managed with colostomy during the study period. The patients comprised of 68 males and 42 females. High anorectal malformation accounted for 66 babies [males 48, females18] while Hirschsprung’s disease was the surgical indication in 44 [males20, females24]. The age at colostomy ranged from 1day to 4 years. A total of 32 complications were recorded in 25patients [29%]. There were 4 deaths [3.6%]. Early complications like Haemorrhage and septicaemia was seen 4 patients. Colostomy stenosis was observed in 3 cases requiring only dilatation. Colostomy prolapse was seen only in 3 patients [3.24%]. Skin excoriation was the commonest complication, noted in 10 patients. Failure to thrive secondary to colostomy diarrhoea was observed in 3 patients. Superficial wound dehiscence occurred in 3 babies. Urinary tract infection seen in 5 and Intestinal obstruction requiring laparotomy occurred in one baby.Conclusions: Colostomy prolapse is very common after loop colostomies. Rectus muscle splitting incision for loop colostomies is safe and is associated with low incidence of colostomy prolapse.

O trabalho faz uma avaliação da relação entre o Modelo Dinâmico, que preza pela reclassificação das contas do Balanço Patrimonial para definir um perfil financeiro e uma análise de tendência com o modelo Valor Econômica Agregada (EVA®) que objetiva verificar se o capital empregado foi superior ou inferior ao Custo Médio Ponderado de Capital, para que seja criado ou destruído valor econômico para os acionistas. Criado com objetivo de verificar a possível relação entre os modelos. Tendo como base de dados às demonstrações contábeis das empresas do setor de Construção Civil listadas na BOVESPA de 2009 a 2013. A problemática proposta é analisar a comparação entre Modelo Dinâmico e o EVA para a geração ou destruição de valor aos acionistas. Na análise do Modelo Dinâmico ocorreu um baixo risco de insolvência no setor, a não ser pelo ano de 2011. Já no EVA foi identificado que apenas em 2011 e 2012 não foram gerados valor econômico aos acionistas devido ao ROCE inferior ao WACC, sendo mais acentuado no ano de 2012, o que permite concluir que não se pode afirmar veementemente que as empresas analisadas no Modelo Fleuriet que apresentam bons resultados estão de fato agregando riqueza ou valor econômico aos seus acionistas.

Este artigo trata da expansão da fronteira agrícola em Porto Nacional– TO e aborda os possíveis impactos do uso de produtos agroquímicos na saúde do trabalhador do campo. A expansão da área de cultivo de grãos no município a partir de 1999 está associada à instalação de infraestrutura de escoamento da safra, ao baixo custo da terra e aos incentivos fiscais. Das 234 empresas do ramo do agronegócio instaladas em Porto Nacional, 19%comercializam produtos agroquímicos, os quais contribuíram para o incremento do número de casos de intoxicação e óbitos associados a esses produtos. O desconhecimento sobre os riscos e normas de segurança, as dificuldades de fiscalização, a livre comercialização e a pressão comercial das empresas distribuidoras e produtoras podem agravar a situação. O número de empresas de agroquímicos pode indicar os riscos à saúde dos trabalhadores e contribuir nas ações de planejamento e vigilância.

Published: November 2017

Actualmente la industria alimentaria ha generado interés en edulcorantes no nutritivos, por ejemplo la Stevia y en componentes especiales como la L-carnitina, utilizados en formulaciones de suplementos nutricionales para  el control glicémico específicos para  diabéticos. El presente estudio evaluó el efecto de la stevia y la L-carnitina  sobre el índice glicémico(IG) y la carga glicémica (CG) de un suplemento nutricional en 19 sujetos sanos (09 hombres y 10 mujeres), quienes completaron aleatoriamente 3 pruebas de consumo, 1 para el suplemento y 1 para cada producto de referencia: solución glucosada (SG) y pan blanco(PB), obteniendo muestras de sangre a los tiempos 0, 15, 30, 45, 60, 90 y 120 min; para medición de glicemias, e insulina basal y post-prandial. El área de incremento bajo la curva de glucosa (IAUC) fue menor para el suplemento 11778,73 que para los productos de referencia  (SG) 13724,06; (PB) 13153,56  α=p 0,005. El IG= (62) y la CG = (16) resultaron intermedios y más bajos que el del pan blanco IG= (69) y la CG = (18), sin diferencias en la insulina post-prandial. Esto demuestra que este suplemento nutricional formulado con stevia y L-carnitina es capaz de prolongar la respuesta glicémica sin aumentar los requerimientos insulínicos en sujetos sanos. Se requieren estudios específicos en diabéticos para  validar si el impacto glicémico es menor que el producto patrón. La presencia de otros nutrientes en la fórmula, influyentes en estos indicadores, no permite inferir que los resultados se deban únicamente al tipo de endulzante utilizado y a la L-carnitina.
OSTEOPROTECTIVE MEDICINAL PLANTS - PART 1 (A HUMAN CLINICAL EVIDENCE-BASED REVIEW)
Authors: Dragos Dorin , Gilca Marilena , Gaman Laura , Stoian Irina , Lupescu Olivera
Published: November 2017

Background. Osteoporosis is a bone metabolic disease affecting a large percentage of aging population, which leads to an increased risk of fractures and has a negative impact on life quality. The available treatments for osteoporosis are effective, but are associated with several severe adverse reactions, hence the interest for alternative treatments devoid of such redoubtable side effects. Medicinal plants represent a viable resource for new therapeutic agents.

The purpose of this review is to provide an overview about the medicinal plants that have been reported to have anti-osteoporotic effects in human clinical studies.

Materials and Methods. Relevant studies found in PubMed database, pertaining to efficacy in humans, mechanism of action, osteoactive phytochemicals and safety, were selected. For the inquiry, keywords such as “medicinal plant”, “osteoporosis”, “bone”, “fracture”, “osteoclast” and “osteoblast” were used in various combinations. The information extracted was integrated with the traditional knowledge on the correspondent medicinal plants. Results. Eight medicinal plants (Cimicifuga racemosa, Cissus quadrangularis, Eleutherococcus senticosus, Epimedium spp., Glycine max, Pueraria spp., Panax notoginseng, Salvia milthiorriza) were selected. Mechanisms involved include the activation of osteoblasts, inhibition of osteoclastogenesis, estrogen-like activity, anti-inflammatory activity, inhibition of collagen degradation by cathepsin K.

Conclusion. Several medicinal plants have been included in clinical studies successfully targeting osteoporosis, thus showing the potential to modulate bone resorption and bone formation.

Above‐ and Belowground Development of a Fast‐Growing Willow Planted in Acid‐Generating Mine Technosol
Authors: Guittonny‐Larchevêque M. , Lortie S.
Published: November 2017

Surface metal mining produces large volumes of waste rocks. If they contain sulfide minerals, these rocks can generate a flow of acidic water from the mining site, known as acid mine drainage (AMD), which increases trace metals availability for plant roots. Adequate root development is crucial to decreasing planting stress and improving phytoremediation with woody species. However, techniques to improve revegetation success rarely take into account root development. An experiment was conducted at a gold mine in Quebec, Canada, to evaluate the establishment ability over 3 yr of a fast‐growing willow (Salix miyabeana Sx64) planted in acid‐generating waste rocks. The main objective was to study root development in the soil profile and trace element accumulation in leaves among substrates varying in thickness (0, 20, and 40 cm of soil) and composition (organic carbon [OC] and alkaline AMD treatment sludge). Trees directly planted in waste rocks survived well (69%) but had the lowest productivity (lowest growth in height and diameter, aerial biomass, total leaf area, and root‐system size). By contrast, the treatment richer in OC showed the greatest aerial biomass and total leaf area the first year; the thicker treatment resulted in the greatest growth in height and diameter, aboveground biomass, and root‐system size in both the first and third years. Willow root development was restricted to soil layers during the first year, but this restriction was overcome in the third year after planting. Willow accumulation factors in leaves were below one for all investigated trace metals except for zinc (Zn), cadmium (Cd), and strontium. For Cd and Zn, concentrations increased with time in willow foliage, decreasing the potential of this willow species use for phytostabilization, despite its ability to rapidly develop extensive root systems in the mine Technosol.

Core Ideas

Salix miyabeana grew roots extensively in shale waste rocks, even if AMD generating.

Root development in waste rocks was delayed at least 1 yr under soil layers.

A soil layer of 40 cm maximized root system size after 3 yr.

Soil layer thickness rather than organic matter content determined sustained productivity.

Salix miyabeana accumulated Cd and Zn in foliage over time, especially with soil layers.
Application of Synchrotron Radiation‐based Methods for Environmental Biogeochemistry: Introduction to the Special Section
Authors: Hettiarachchi Ganga M. , Donner Erica , Doelsch Emmanuel
Published: November 2017

To understand the biogeochemistry of nutrients and contaminants in environmental media, their speciation and behavior under different conditions and at multiple scales must be determined. Synchrotron radiation‐based X‐ray techniques allow scientists to elucidate the underlying mechanisms responsible for nutrient and contaminant mobility, bioavailability, and behavior. The continuous improvement of synchrotron light sources and X‐ray beamlines around the world has led to a profound transformation in the field of environmental biogeochemistry and, subsequently, to significant scientific breakthroughs. Following this introductory paper, this special collection includes 10 papers that either present targeted reviews of recent advancements in spectroscopic methods that are applicable to environmental biogeochemistry or describe original research studies conducted on complex environmental samples that have been significantly enhanced by incorporating synchrotron radiation‐based X‐ray technique(s). We believe that the current focus on improving the speciation of ultra‐dilute elements in environmental media through the ongoing optimization of synchrotron technologies (e.g., brighter light sources, improved monochromators, more efficient detectors) will help to significantly push back the frontiers of environmental biogeochemistry research. As many of the relevant techniques produce extremely large datasets, we also identify ongoing improvements in data processing and analysis (e.g., software improvements and harmonization of analytical methods) as a significant requirement for environmental biogeochemists to maximize the information that can be gained using these powerful tools.

Core Ideas

SR‐based techniques have revolutionized the field of environmental biogeochemistry.

Improvements to light sources will provide SR with extreme brightness and coherence.

This should be met with similar advances to synchrotron‐related hardware and software.

Environmental biogeochemists can drive the new advances in the synchrotron science.

Advances in SR will enable future breakthroughs in environmental biogeochemistry.
Phosphorus Release from Mineral Soil by Acid Hydrolysis: Method Development, Kinetics, and Plant Community Composition Effects

Core Ideas

A modified pHstat approach captures P release kinetics in soil relevant for plant nutrition.

The fast‐reacting P pool comprises P from charged surfaces and easily soluble Ca‐phosphates.

The slow‐reacting P pool is a mixture of Ca‐phosphates and P released by dissolution of pedogenic oxides.

Legumes increase the exploitation of more stable P pools.

The release kinetics of phosphate (inorganic P [Pi]) at constant proton pressure in a pHstat experiment may be used as a proxy for P mobilization by rhizosphere acidification. pHstat experiments are challenging for calcareous soils because of the strong carbonate buffering. Our objectives were (i) to modify an existing pHstat method for calcareous soils and (ii) to determine plant species richness, plant functional group richness, and identity effects on pool sizes and rate constants (i.e., the fast‐ and slow‐reacting Pools A and B, respectively, and the associated release constants ka and kb). The study was conducted in “The Jena Experiment” comprising grassland mixtures with different functional group composition and species richness. In 27 samples with inorganic C concentrations <10 g kg–1, a constant pH value of 3 after 2 h was reached by removing all released cations with ion‐exchange membranes until all carbonates were destroyed. Thereafter, P release kinetics followed a biphasic course: the fast‐reacting Pool A contained 86% of the bioavailable Pi extractable with NaHCO3 plus NaOH. The slow‐reacting P pool additionally comprised P from dissolution of pedogenic oxides and more stable Ca‐phosphates containing 17 to 40% of HCl‐extractable Pi. Legumes decreased both pools (Pool A: 40.61 ± 3.83 with legumes vs. 65.24 ± 5.88 mg kg–1 Pi without legumes; Pool B: 36.88 ± 1.89 vs. 48.85 ± 1.81 mg kg–1 Pi) because of their increased P demand and associated ability to access hardly available P fractions. In conclusion, pHstat experiments are suitable for studying P dynamics in soil and reveal an aboveground plant composition feedback on soil P dynamics.

Published: November 2017

Southwest coastal Bangladesh has an acute scarcity of safe drinking water. Both the government and non-government organizations are now promoting reverse osmosis based small scale desalination plants (SSDPs) to ensure safe drinking water. The aim of this study was to assess the physico-chemical and bacteriological quality of the desalination plants (DPs) installed in southwest coastal Bangladesh. Water samples were collected from the inlet and outlet of 10 DPs. The product water mostly complied with water quality standards. High levels of total dissolved solids (TDS) and electrical conductivity (EC) in feed water were reduced significantly after the treatment, although 10% and 20% of the product water samples respectively did not comply with the WHO drinking water standards for those parameters. Compliance of product water with the WHO and Bangladesh drinking water standards for chloride, bicarbonate and sodium were found in respectively 80%, 90% and 70% of the samples, although their concentrations in all the feed water samples were higher than both of the standards. About one-third of the DPs did not meet the drinking water standard for sodium, which may be an important health concern for the people consuming this water. Apart from one of the DPs, all of them complied with the standard for faecal coliform and Escherichia coli. Results suggest that proper maintenance of the SSDPs is necessary to ensure safe drinking water for the coastal population of southwest Bangladesh.

En el presente artículo se expone el Método de la Secuencia de la Investigación desarrollado por James Spradley. Este procedimiento figura entre uno de los enfoques globales más importantes en los estudios cualitativos. La estrategia de Spradley fue diseñada de forma didáctica para orientar los trabajos de investigadores noveles cuya principal técnica de recopilación de información es la entrevista etnográfica. El trabajo de campo convierte al observador en un instrumento de investigación. En este sentido, es necesario contar con recomendaciones procedimentales para el adecuado estudio de las personas en sus escenarios vitales: lugares de trabajo, barrios, hospitales, escuelas, entre muchos espacios donde los individuos desarrollan su cotidianidad. Las orientaciones básicas para la observación y tratamiento de la información se exponen a través de una serie de etapas. La información procede del estudio de fenómenos vinculados a diversas ramas de las ciencias sociales y de la salud que estudian a las personas en sus contextos de vida. Los pasos de este método van creando esquemas conceptuales que orientan la forma de realizar el análisis de la información, obtenida del corpus de las entrevistas. El investigador recibe sugerencias que lo sitúan constantemente entre el análisis de los datos y la recopilación de información en el trabajo de campo. La utilización de este tipo de estrategia repetitiva permite adecuar la observación fundamentada en las preguntas y objetivos del estudio que se realiza, y resulta de gran ayuda para la obtención de datos que guíen la investigación hacia resultados atinentes en el proceso de conocer, describir y obtener recomendaciones para la intervención en los contextos estudiados.
THE INTERPRETATIVE AUTOETHNOGRAPHY AS A QUALITATIVE METHODOLOGY TO HUMANIZE SOCIAL RESEARCH IN LATIN AMERICAN TRANSBOUNDARY CONTEXTS
Authors: Zapata Sepúlveda Pamela
Published: November 2017

This paper aims to connect the present moment of contemporary Qualitative Inquiry with the Latin American qualitative inquiry audience from an interdisciplinary approach. In order to do so, the main statements that place the QI in present times will be presented, specifically the tradition of interpretative autoethnography understood as a form of critical research that seeks to sensitize, to evoke and to transform realities through experimental writing as a way of investigating. This methodology, widely used in research projects in English speaking countries to address injustices and problems that affect the lives of voiceless people, allows to relay knowledge from the self, the ethno, to the social. In this paper, a bibliographical review about the method is conducted and addresses an example taken from field work experience in the project Fondecyt regular Nº 1160869 "Relationships and social interactions of children of immigrants and Chilean children in the schools of Arica". The applications and contributions of this methodology for social research are discussed through the voice of a Latin American woman who develops her research line from a border region, and how these methodologies can address the caretaking of the participants of the study.

Authors: Rubilar Donoso Gabriela
Published: November 2017

This article reviews the scope and potential of research done using a biographical approach and the role that this approach adopts in giving voice to experiences lived by the subjects. Special emphasis is placed on the use of narratives to construct life stories, histories and testimonies, incorporating elements for a discussion about their use and enhancement as an approach for research and intervention. This article is written from an interdisciplinary perspective, recognizing the strengths of this approach that can be applied to diverse disciplines within social sciences, humanities and health sciences. This paper analyzes the trends that have influenced in studies from a biographical approach, considering historical and epistemological aspects. This is particularly relevant for disciplines related to human care, such as Nursing or Social Work that deal with narratives of participants who have faced situations of pain or illness. The narrative-biographical approach allows us to retrieve these histories and to contribute to the memories of people willing to narrate their experiences. The article concludes by examining the contemporary uses of this approach both in research and in social interventions. Current challenges related to this approach are discussed and also the possibility of combining it with multimedia devices and the use of information technology.
QUALITATIVE RESEARCH AND EDUCATION: TENSIONS IN ITS PROPOSAL, DEVELOPMENT, WRITING AND PUBLICATION
Authors: Johnson- Mardones Daniel F
Published: November 2017

This paper explores the tensions in qualitative research and education. With this objective, it offers a brief introduction to qualitative research in education, a vision of the historical link of these two fields of study, to lead to a reflection between the thematic and the methodological when we talk about qualitative methodologies in education. Under that approach, the text focuses on the tensions that appear in the formulation of a proposal, development, writing and publication of a qualitative research in education. The tensions in the proposal are concentrated in the formats of formulation and presentation of research projects when we construct the object of study from a qualitative perspective. In the development of the research, time appears as a central concern from various points of view, as well as the tension between the order of analysis and the order of presentation. The writing is approached from the tension between the option for an argumentative text and a narrative text. Finally, the tensions in the publication focus on sending manuscripts to thematic journals or journals specialized in methodology. The tensions in each of these moments of qualitative research in education are explored from the point of view of their possibilities.
LA IDENTIDAD INDÍGENA INTERPRETADA COMO UNA CATEGORÍA DE ANÁLISIS EN LOS ESTUDIOS DE POBLACIÓN
Authors: Choque-Caseres Dante
Published: November 2017

En Latinoamérica, a partir del reconocimiento de los Pueblos Indígenas, la identificación de brechas o disparidades entre la población Indígena y no Indígena ha emergido como un interés investigativo. Con este fin, capturar la identidad Indígena es clave para conducir algunos análisis. Sin embargo, los contextos sociales donde se (re)produce la identidad de las personas Indígenas han sido alterados significativamente. Dichos cambios son producidos por la asimilación o integración de las comunidades Indígenas a las culturas nacionales dominantes. En este contexto emergen limitaciones en el uso de esta categoría, puesto que la identidad Indígena tendría un componente político y legal relacionado con las necesidades de los gobiernos. Por lo tanto, una reflexión crítica sobre el uso de la identidad Indígena es necesaria en los enfoques epistemológicos y metodológicos de investigación. Este artículo argumenta que la investigación sobre pueblos Indígenas debería evaluar el cómo es incluida la identidad Indígena, porque ésta es socialmente co-producida en la interacción con el Estado y sus instituciones. De esta forma, ella no necesariamente podría constituir una variable explicativa. A través del análisis de discursos acerca de personas y comunidades Indígenas Aymaras que han emergido en la frontera norte de Chile busco exponer las lógicas empleadas para definir la identidad. Se concluye, entonces, que paulatinamente el proceso de auto-identificación emerge en supuestos Indígenas constituidos y/o reforzados por las instituciones, los cuales deberían ser revisados desde un enfoque descolonizado para ser incluidas en investigaciones comparativas.
THE POETRY AND ITS LITERARY RESOURCES AS QUALITATIVE METHODOLOGY
Authors: González-Gutiérrez Luis F
Published: November 2017

This article describes the main contributions of poetic inquiry as a critical qualitative methodology for the social sciences and health sciences. Are first explored the present research trends associated with the use of poetry as a narrative construction form; in a second, the use of specific exercises is analyzed to identify the potential of narrative aesthetics in the construction of alternative subjectivities as a way of recognizing the voice of the research participants. Finally, there is an academic and reflective discussion about the need to use this methodology in the different universities and study centers in Latin America. It can be concluded that poetic research is a critical way of approaching community problems based on the voice of its participants. It is also a methodology that unites researchers and their participants in a generative dialogue, which enhances qualitative research.
Pesquisar o/no cotidiano na pesquisa social:
Authors: Spink Mary Jane Paris , Spink Peter Kevin
Published: November 2017

Este artigo tem por objetivo discutir a trajetória que leva da inserção do cotidiano como foco de pesquisa às problematizações recentes sobre lugar e território. São abordados três momentos distintos de reflexão acerca do cotidiano, trabalhados como “viradas” conceituais com implicações metodológicas. Iniciamos abordando sucintamente a “virada para o mundo vivido” nas décadas de 1960-1980. A seguir, apontamos para uma segunda virada que provém de discussões na geografia e na teoria social sobre “lugar” e, mais tarde, sobre “território”, nas suas vertentes de “território vivido” e território de vivência”. Propomos que estamos vivenciando uma terceira virada, que tem por foco redes heterogêneas e cadeias de associações entre humanos e não humanos, decorrentes de aproximações com a Teoria Ator Rede e com a discussão atual na geografia a respeito de multiterritorialidades. Finalizamos comentando a importância de se repensarem as posturas de investigação quando localizamos a pesquisa no cotidiano.

A metodologia de Reunião em Espaço Aberto, ou Open Space–OST, foi criada ou “iniciada” pelo estadunidense Harisson Owen em 1997 e apresenta a junção de elementos de várias culturas ancestrais, como o caso do “bastão de falar” presente nas reuniões de círculo nas aldeias africanas, indígenas e em aldeias no interior de Portugal, os “jornais de parede, ou mercados tradicionais” presentes em culturas medievais e contemporâneas, o “respeito pelo outro” das culturas orientais. A partir dos desafios propostos aos professores no espaço aberto, foram produzidos vídeos com músicas, mapas conceituais, paródias, poesias e histórias animadas com o Scratch. Ao fim de cada atividade os participantes eram convidados a produzir uma narrativa crítico-reflexiva sobre a experiência vivenciada. A experiência descrita é parte de uma pesquisa de doutorado em Educação, em andamento e conta com o financiamento integral por meio de bolsa PROSUP/CAPES.
Elucidating nuclear size control in the Xenopus model system
Authors: Jevtic Predrag , Levy Daniel
Published: November 2017

Background. Nuclear size is a tightly regulated cellular feature. Mechanisms that regulate nuclear size and the functional significance of this regulation are largely unknown. Nuclear size and morphology are often altered in many diseases, such as cancer. Therefore, understanding the mechanisms that regulate nuclear size is crucial to provide insight into the role of nuclear size in disease. Scope and Approach. The goal of this review is to summarize the most recent studies about the mechanisms and functional significance of nuclear size control using the Xenopus model system. First, this review describes how Xenopus egg extracts, embryos, and embryo extracts are prepared and used in scientific research. Next, the review focuses on the mechanisms and functional effects of proper nuclear size control that have been learned using the Xenopus system. Key Findings and Conclusions. Xenopus is an excellent in vivo and in vitro experimental platform to study mechanisms of nuclear size control. Given its close evolutionary relationship with mammals and that most cellular processes and pathways are highly conserved between Xenopus and humans, the Xenopus system has been a valuable tool to advance biomedical research. Some of the mechanisms that regulate nuclear size include components of nuclear import such as importin ? and NTF2, nuclear lamins, nucleoporins, proteins that regulate the morphology of the endoplasmic reticulum, and cytoskeletal elements.

Evaluation of Interfacial Gap Volume of Two Low-shrinkage Composites Using Micro–Computed Tomography
Authors: Nahedh HNA Al , Sibai NS
Published: November 2017

Objectives:

To investigate the efficacy of X-ray micro–computed tomography (μCT) in the detection and quantification of interfacial gap formation in standardized Class I and Class II resin composite restorations, to compare the interfacial gaps for two low-shrinkage resin composites with a methacrylate composite material, and to determine any correlation between the cavity configuration factor (C-factor) and the volume of gaps formed.

Methods and Materials:

Sixty standardized Class I and Class II cavities were prepared and divided into six groups. Three types of composites, with their recommended self-etching adhesive systems, were used: Filtek Z250 XT; Estelite Sigma Quick; and Filtek P90. Each of the composite materials was placed in 10 Class I and 10 Class II cavities. The specimens were digitized using Skyscan 1172 μCT. They were examined for gap volume measurements, the thickness of the adhesive layer, and location of interfacial gaps.

Results:

There was a significant difference in the mean gap volume percentages of the three materials. The gap volume percent of Estelite Sigma quick was significantly lower than that of Filtek P90. No significant difference in the mean gap volume percentages of Class I and Class II restorations was found, except for Estelite Sigma Quick, in which the Class I gap volume percentage was higher than that of the Class II restorations.

Conclusions:

μCT is an efficacious tool for the measurement of volumetric gaps formed at the tooth/restoration interface and for the evaluation of the adhesive layer. The differences in the C-factor do not always have a pronounced effect on the gap volumes of low-shrinkage composites.
Effect of Preparation Designs on the Prognosis of Porcelain Laminate Veneers: A Systematic Review and Meta-Analysis
Authors: Hong N , Yang H , Li J , Wu S , Li Y
Published: November 2017

Objective:

To investigate the association between preparation designs and prognosis of porcelain laminate veneers (PLVs).

Methods:

Electronic and manual literature searches were performed in Medline, Embase, CENTRAL, and Scopus databases for randomized controlled trials and retrospective and prospective cohort studies comparing any two of three preparation designs. The quality of the included studies was assessed using the Newcastle-Ottawa scale. Pooled hazard ratios and risk ratios were used to evaluate the difference between two preparation designs. Subgroup analyses, sensitivity analysis, and evaluation of publication bias were performed if possible.

Results:

Of 415 screened articles, 10 studies with moderate to high quality were included in the meta-analysis. Comparison of preparations with incisal coverage to preparations without coverage revealed a significant result based on time-to-event data (hazard ratio=1.81, 95% confidence interval [CI]=1.18-2.78, I2=12.5%), but the result was insignificant based on dichotomous data (risk ratio=1.04, 95% CI=0.59-1.83, I2=42.3%). The other comparisons between any two of overlap, butt-joint, and window types revealed no statistically significant difference. Subgroup analyses regarding the porcelain materials, location of prosthesis, and tooth vitality could account for only part of the heterogeneity. No evidence of publication bias was observed.

Conclusions:

Within the limitation of the present study, it can be concluded that preparation design with incisal coverage for PLVs exhibits an increased failure risk compared to those without incisal coverage. The failure risk of the overlap type may be higher than the butt-joint type but must be validated in further studies.
OUTPLACEMENT COMO HERRAMIENTA ESTRATÉGICA PARA REDUCIR MOMENTOS DE INCERTIDUMBRE EN ORGANIZACIONES: UNA PERSPECTIVA REFLEXIVA Y ATEMPORAL
Authors: Briceño Denny José Pereira , Parra Doile Enrique Rios
Published: November 2017

La presente investigación tuvo como principal propósito Comprender el outplacement como herramienta estratégica para la reducción de momentos de incertidumbre en organizaciones. La misma se sustentó teóricamente en autores como Licht, A. (2003), Muñiz (2008), Carmona (2009), León (2006) entre otros. Epistemológicamente, la investigación tiene un abordaje cualitativo, con un método de investigación de tradición cualitativa Fenomenológica. Los tripulantes clave fueron seleccionados de diferentes organizaciones con diversas filosofías y atención, teniendo como única similitud su razón social inicial, donde la constitución de estas fue bajo una economía privada y hoy en día son empresas adscritas al gobierno nacional. En cuanto a la técnica de recolección se empleó la observación participante y la entrevista en profundidad, constituida por una guía semiestructurada y como instrumento se recurrió a la grabadora portátil y los registros descriptivos. Las técnicas de análisis se desarrollaron a través de la categorización, estructuración, triangulación y teorización, en base al método de microanálisis propio de la teoría fundamentada propuesto por Strauss y Corbín (2002) para el tratamiento de la data. Entre los resultados destacados se pudo constatar la necesidad de construir una teoría sustantiva que explique el outplacement como herramienta estratégica para la reducción de momentos de incertidumbre en organizaciones. Se concluyó que en las instituciones existen ficciones de técnicas o programas para un proceso adecuado de transición y/o cambio de filosofía organizacional. Se recomienda el outplacement como herramienta estratégica en las organizaciones, en las que la productividad no es el único fin, sino que es relevante los procesos de manera de obtener en los empleados desvinculados esa aceptación, encontrando esta situación como una oportunidad de cambio; que no necesariamente tiene que ser limitante, por el contrario puede ser vista como una opción de mejoramiento a nivel personal, laboral y profesional.
EVALUACIÓN METROLOGICA DE LA ESTRUCTURA OPTITRACK-MOTIVE PARA EL RASTREO DE OBJETOS EN EL ESPACIO QUIRÚRGICO APLICADO EN PERFORACIÓN DE TUNELES TIBIAL Y FEMORAL EN RECONSTRUCCIÓN DE LIGAMENTO CRUZADO ANTERIOR DE RODILLA

Published: November 2017

Un alto porcentaje de cirugías de Reconstrucción de Ligamento Cruzado Anterior son fallidas debido al mal posicionamiento de los túneles tibial y femoral. Para esto se diseñó un sistema, basado en la estructura Optitrack-Motive, que, usando Realidad Aumentada, apoya el proceso de perforación de los túneles realizando el seguimiento de marcadores pasivos por visión estéreo para ubicar el instrumental en el campo quirúrgico. Sin embargo, en la literatura no existe información acerca de la precisión en el posicionamiento del sistema Optitrack-Motive. Debido a esto se hizo necesario realizar este estudio para verificar la precisión requerida para esta aplicación quirúrgica. Se posicionó una barra de calibración lineal en el volumen de trabajo y se midieron distancias a diferentes planos de observación con dos sistemas de exploración 3D: Motive-Tracker y un software construido en C++. El análisis de error sugiere que las fuentes aleatorias introducen una desviación estándar que no supera 39 micras para ambos casos, siendo más pequeña en la zona central para el software C++. El análisis del sesgo depende de las posiciones de las esferas en cada cámara. Para el software C++ la zona central es más corregida de la influencia de distorsiones geométricas, introduciéndose menos error en el cálculo de distancias: 22 micras para medir 87.5 mm. Para el software Motive-Tracker el error determinístico es más pequeño y homogéneo en todo el espacio de calibración: Medir una distancia de 250 mm se introduce un error absoluto máximo de 0.343 mm, siendo mínimo de 0.059 mm para Z=90 cm.
