Apropiación del recurso forestal en la amazonia colombiana: una mirada desde la bioética
Authors: Landínez Torres Ángela Yaneth
Published: April 2017

El presente estudio analiza la participación de los principios bioéticos, en el abordaje de los conflictos que emergen de las prácticas de uso y manejo de los recursos forestales en la amazonia colombiana, en los contextos indígena y urbano. La propuesta de corte teórico caracteriza a nivel biológico y cultural las formas de apropiación forestal, además de describir y analizar las problemáticas asociadas con dicha actividad. Los resultados se sistematizan en una matriz comentada para cada uno de los contextos de estudio, desde dos elementos, el YO (Estructura): aspectos culturales, cosmovisión, formas de conocimiento y el OTRO (Interacciones): relaciones ecológicas y tecnológicas. Asimismo, identifica a la ética convergente, propuesta por
Maliandi y Thüer, como una valiosa herramienta en la resolución de este tipo de problemas ambientales, dado que considera las estructuras conflictivas: diacrónica y sincrónica; la bidimensionalidad de la razón: fundamentación y crítica, así como los principios biotecnoéticos: precaución, exploración, no discriminación y respeto a la diversidad genética. Finalmente, propone el diálogo de saberes, interdisciplinario y plural, como una importante forma de armonización y plantea los principios bioecoéticos, que incluyen a las entidades y los sistemas no humanos, como útil instrumento en el tratamiento de la conflictividad en esta área.

Se plantea la situación teniendo en cuenta la evolución del concepto del niño de objeto de derecho a sujeto de derechos. Con base a una experiencia de investigación se analizan diferentes principios relativos a la bioética en el contexto del maltrato infantil y se proponen alternativas de solución desde esta perspectiva.
Bioética y Universidad en América Latina. Propuesta de una estructura para la formación integral profesional
Authors: Linares Márquez Pascual , Fraile Laiz Benito
Published: April 2017

En el presente trabajo hacemos una revisión del desarrollo de la bioética en América latina. Se señalan los enfoques que diversos autores apuntan para integrar la bioética en las universidades de la región. Asimismo se considera la importancia de integrar la bioética a la vida universitaria con la intención de fomentar una formación profesional integral con bases axiológicas robustas. Desde la revisión de la bioética y los avances en la región, se elabora una propuesta de estructura bioética en la universidad, la cual tendrá como intención mejorar los aspectos éticos en las carreras de grado y en el posgrado de todas las disciplinas que de alguna forma están relacionadas directa e indirectamente con la conservación de la vida humana y no humana desde el servicio profesional. Con ello se busca contribuir a mejorar la calidad de vida de los seres humanos.
Educación en Bioética, laicidad y ética pública
Authors: Escobar Triana Jaime Alberto
Published: April 2017

La Bioética debe encontrar todo aquello que une a la humanidad para tener bases éticas desde las cuales respetar y avalar las diferencias que nos separan, teniendo en cuenta esto, el artículo plantea reflexiones alrededor de tres categorías: la laicidad, la Bioética y la educación en Bioética. Se propone que: 1) la laicidad implica la expansión del ejercicio de los derechos personales en un marco de convivencia civil, pero significa un respeto esencial a la libertad de conciencia, al libre desarrollo de la personalidad, sin la imposición de una moral determinada a los ciudadanos; 2) la enseñanza de la Bioética debe estar adecuada a las condiciones de la civilización actual, permitiendo la presencia de diversas creencias religiosas y promoviendo el respeto por los derechos humanos así como su protección por parte del Estado, debe ser laica y aconfesional; 3) la Bioética debe convertirse en un campo de reflexión y discusión de los problemas del mundo de la vida y procurar permear las políticas públicas de los países en aras de la construcción de sociedades verdaderamente laicas y democráticas.

Del conflicto armado al conflicto político en Benjamín y Freud
Authors: De Zubiría Sergio
Published: April 2017

Cuando ingresamos en la problemática que convoca a este seminario «Del conflicto armado al conflicto político», concluimos que lo que vamos a abrir hoy es una agenda de investigación bastante abierta y más en nuestra condición de colombianos y colombianas. La agenda es bastante urgente. Walter Benjamin, en una reflexión juvenil llamada La vida de los estudiantes, dice que la calidad espiritual de una comunidad la determina la profundidad de sus preguntas. Y el maestro Jesús Martín Barbero nos recuerda permanentemente que una buena pregunta es una agenda de investigación. Esta exposición tiene dos grandes bloques. El primero «La agenda pendiente», casi lo que viene después de este seminario, y es que cuando uno aborda la problemática del conflicto, tanto en Colombia como en cualquier otra latitud, hay unos desafíos teóricos y prácticos, que hay que tener claros en el horizonte. El segundo bloque, algunas pistas que dadas por Walter Benjamin y Sigmund Freud, para pensar el tema de este seminario: ¿cómo hacer que un conflicto armado termine en un conflicto político?
Diagnóstico, tratamiento e investigación en pacientes con demencia. Tensiones y significado
Authors: Saavedra Estupiñán Myriam
Published: April 2017

Esta investigación tuvo como objetivo identificar las tensiones que emergen entre los significados de los pacientes con demencia y sus asistentes, cuando toman decisiones sobre la atención en salud respecto a diagnóstico y tratamiento, o su participación en proyectos de investigación, en la Clínica de Memoria de la Facultad de Medicina de la Universidad Nacional de Colombia, sede Bogotá. Es un estudio descriptivo comprensivo, de corte transversal, que utilizó como estrategia de investigación las técnicas de revisión documental, cuestionarios y entrevistas. Se estableció el compromiso cognoscitivo y comportamental de los pacientes y se identificaron los significados no en términos lingüísticos, sino de la interpretación personal que atribuyen al diagnóstico y tratamiento de la demencia en el aspecto asistencial, y a la posibilidad hipotética de participar en proyectos de investigación relacionados. Durante el análisis se identificaron las tensiones entre esos significados y se cualificaron, según los principios bioéticos reconocidos. Como
hallazgo, emergió de los datos un principio: el altruismo.
Respeto a la autonomía de mujeres gestantes en salud: diálogo bioética-género
Authors: Urrea Mora Fanny Consuelo
Published: April 2017

A partir del diálogo bioética-género, se realizó una investigación cualitativa con el propósito de relacionar significados que del cuerpo y el ejercicio de la autonomía tenían mujeres embarazadas y profesionales de salud (odontólogos/as, médicos/as y enfermeras/os). Se formaron 9 grupos focales (GF) y se realizaron 19 entrevistas semiestructuradas: 9 a mujeres gestantes (MG) y 10 a profesionales de la salud (PS), que
las atendieron en los hospitales de Suba, Engativá y Usaquén, de la red Norte de la Secretaría Distrital de Salud de Bogotá1 entre 2010 y 2012. El análisis, mediante una perspectiva en paralelo, mostró encuentros y desencuentros de dos mundos diferentes: el de las MG y el de los /las PS entorno al significado de la maternidad, el cuerpo, la boca y el ejercicio de la autonomía durante la atención en salud. Los hallazgos revelaron que el respeto a la autonomía de las MG durante la atención en salud, está mediado por los significados que del cuerpo y la autonomía femenina tienen tanto las mujeres como los PS que las atienden.
Redescription of Dawndraco kanzai Kellner, 2010 and reassignment of the type specimen to Pteranodon sternbergi Harksen, 1966
Authors: Martin-Silverstone Elizabeth
Published: April 2017

The previous most comprehensive study on Pteranodon recognized two species of Pteranodon: P. longiceps and P. sternbergi. Complete skeletons of Pteranodon are rare, and one of the best preserved (UALVP 24238) has been identified as both P. sternbergi, and as a new genus and species, Dawndraco kanzai.  Here, the specimen is redescribed, the rostral apex is identified for the first time, new details of its provenance and preparation history are presented, and its taxonomic placement is discussed.  Whereas the shape of the rostrum appears at first glance to distinguish it from known Pteranodon, this feature is more parsimoniously interpreted in the context of sexual dimorphism; males have a longer and therefore more shallowly tapering rostrum.  Metrics from this specimen, and from published photographs and illustrations, support the conclusion that the rostrum of UALVP 24238 is neither unique, nor grounds for recognition of a taxon distinct from Pteranodon sternbergi.  Other putatively unique features of UALVP 24238 are examined and found unconvincing.

Published: April 2017

Penicillium expansum, agente causal del moho azul en manzana, causa pérdidas signi­ficativas en frutos de manzana en postcosecha, y es controlado mayormente con fungicidas sintéti­cos. El presente estudio tuvo como objetivo evaluar extractos de hojas de morera (Morus alba) como una alternativa de control del moho azul en frutos de manzana en postcosecha. Once tratamientos, in­cluyendo un testigo químico (Imazalil) y otro sin tratar, se evaluaron in vitro e in vivo. En los experi­mentos in vitro se midieron el crecimiento micelial y la esporulación del hongo, y en los experimen­tos in vivo se midieron la severidad y cambio de color del fruto mediante el análisis de imágenes. Para obtener los extractos de las hojas, se colecta­ron hojas asintomáticas de morera, se trituraron, y se pusieron en agua destilada esterilizada, metanol y acetato de etilo como solventes de separación de fases, o agua destilada, cada uno a concentraciones de 4, 8 y 12 %. Los resultados demostraron que el extracto obtenido conmetanol a 4 y 12 %, y el extracto acuoso a 12 %, inhibieron el crecimien­to micelial. En cuanto a la esporulación del hongo, ésta fue menor en los extractos a base de metanol a 4 y 12 % y el de acetato de etilo a 8 %, igualando al testigo químico. La severidad de la enfermedad en frutos inoculados fue menor en el tratamiento con Imazalil, seguido por el extracto acuoso al 4 %. Solo el tratamiento con acetato de etilo al 8 % cambió la coloración de los frutos.

Published: April 2017

Se determinó la severidad de Phyto­phthora capsicien plantas de chayote y se propuso una escala de severidad, dada su reciente confirma­ción como agente causal de enfermedad. Se mues­trearon plantas con síntomas de marchitez en dos huertos comerciales de chayote en Huatusco, Vera­cruz, México. El oomiceto aislado, a partir de fru­tos y tallos, fue caracterizado morfológica y mole­cularmente e identificado como P. capsici. Plantas de chayote desarrolladas en cámara de crecimiento fueron inoculadas con 1, 3 y 6 x 105 zoosporas 15 días después de la siembra. Se evaluaron la necro­sis de la zona de transición entre el tallo y la raíz, el porcentaje de hojas marchitas y la marchitez de la planta. A los tres días después de la inoculación (ddi) se observó de 2.3 a 3.0 cm de longitud de la necrosis y 50 % de hojas marchitas. A los cinco ddi, la necrosis fue de 2.5 a 3.15 cm y 80 % de hojas marchitas. A los siete ddi, la necrosis fue de 2.67 a 3.3 cm con 100 % de hojas marchitas (planta muer­ta). Con base en los síntomas observados, se diseñó una escala de severidad para evaluar el avance del daño de P. capsicien plantas de chayote bajo con­diciones controladas.

Published: April 2017

Se evaluó el efecto de la inoculación micorrícica de plantas de Agave cupreata en el biocontrol de Fusarium oxysporum y en la promoción del crecimiento vegetal. En invernadero, semillas de A. cupreata fueron inoculadas con cuatro consorcios de hongos micorrícicos arbusculares (HMA) nativos, denominados El Huizachal (EH), Agua Dulce (AD), Paso Ancho (PA) y Cerro del Metate (CM), un inóculo comercial micorriza INIFAP® (MI) y un testigo sin HMA. Siete meses después de inocular los HMA, en un grupo de plantas micorrizadas y sin micorrizar se evaluó la promoción del crecimiento vegetal y otro grupo similar de plantas fueron inoculadas con o sin Fusarium oxysporum FPC (Fox) para evaluar el potencial efecto de biocontrol de los HMA. Los resultados mostraron que la micorrización incrementó significativamente (Tukey, p≤0.05) la biomasa seca total de las plantas, en un intervalo entre 148 y 239 % más con respecto al testigo sin HMA. A los 240 días después de la inoculación de Fox, los tratamientos PA+Fox y MI+Fox mostraron un efecto significativo (Kruskal-Wallis, p≤0.05) en la disminución de la severidad de la marchitez del agave con un promedio de daño de 33 % con respecto al testigo+Fox que presentó daños de 74 %. PA y MI pueden considerarse como potenciales biofertilizantes y agentes de biocontrol de F. oxysporum en el cultivo del agave.

Published: April 2017

El desarrollo de Phaeocryptopus gaeumannii, Ascomycota, causante del Tizón Suizo del follaje de Douglas-fir (Pseudotsu gamenziesii), es influenciado por la composición nutrimental de las acículas. El objetivo del estudio fue examinar el efecto de diferentes elementos esenciales, macro­nutrimentos y micronutrimentos, para las plantas y del silicio (Si), sobre el crecimiento in vitro de P. gaeumannii. Con diferentes nutrimentos y Si se establecieron dos experimentos completamente alazar. El primero fue el cultivo del hongo en Extracto de Malta-Agar al 2 % con 10 tratamientos, y se cal­culó la Tasa de Crecimiento Relativo instantánea; y el segundo fue en medio líquido de Papa Dextrosa con 21 tratamientos, y se midió masa del micelio. Los macronutrimentos favorecieron el crecimiento de P. gaeumannii. En contraste los micronutrimen­tos Cu, Mn y Zn inhibieron el desarrollo del hongo en dosis doble. En general, el Si inhibió el creci­miento del hongo. La solución nutritiva completa de macronutrimentos + micronutrimentos más 250 y 1000 ppm de Si, indicaron que estas formulacio­nes pueden contribuir para eventual control de P. gaeumannii. Este ensayo preliminar in vitro, al pa­recer es el primer estudio.

Published: April 2017

El objetivo de este estudio fue determinar la sensibilidad de Colletotrichum acutatum a los fungicidas metil tiofanato y azoxystrobin, basada en el crecimiento de micelio y germinación de conidios. Se evaluaron 60 aislados monoconidiales de dos regiones productoras de fresa del estado de Michoacán, en medio de cultivo enmendado con 0.001, 0.01, 0.1, 1 y 10, 100 y 2000 µg mL-1 de fungicidas. La dosis efectiva que redujo en un 50% el crecimiento micelial (DE50) del metil tiofanato varió de 0.28 a 9.72 µg mL-1 en el valle de Maravatío y de 1.39 a 2.99 µg mL-1 en el valle de Zamora. En conidios la DE50 varió entre 0.9 a 396.4 µg mL-1 en el valle de Maravatío y de 0.43 a 63.32 µg mL-1 en el valle de Zamora. Para el azoxystrobin las DE50 en micelio variaron de 0.04 a 0.36 µg mL-1 en Maravatío y de 0.07 a 0.99 µg mL-1 en Zamora. En conidios las DE50 variaron de 0.01 a 0.56 µg mL-1 para Maravatío y 0.006 a 0.15 µg mL-1 en Zamora. Las distribuciones de las DE50 indicaron que los aislados de C. acutatum fueron sensibles al azoxystrobin y moderadamente resistentes al metil tiofanato.

Study was conducted to evaluate the performance of Soviet Chinchilla and Californian White rabbit breeds maintained in tropical environment at rabbit research station, Hyderabad, Telangana. Data generated on total of 1364 bunnies, 701 belongings to the Soviet Chinchilla born in 122 litters and 663 bunnies of Californian White born in 124 litters during the period from 2012 to 2015 were utilized to examine the various productive performance traits. The overall least-squares mean litter size and litter weight was 5.52 ± 0.16 and 264.75 ± 7.86 at birth and 3.56 ± 0.17 and 1439.67 ± 72.55 g at weaning, respectively. The overall least-squares mean pre weaning body weights were 48.39 ± 0.48, 113.65 ± 1.38, 161.50 ± 2.03, 226.15 ± 3.47, 417.89 ± 7.53g at birth, 1, 2, 3 and 4 weeks of age and the post weaning weights at 6, 8, 10, 12, 14 and 16 weeks of age were 628.75 ± 13.02, 844.11 ± 14.81, 1040.79 ± 16.42, 1225.96 ± 17.81, 1437.57 ± 20.54 and 1636.99 ± 28.87 g, respectively. Season of birth and litter size at birth showed significant (£0.01) effect on body weights while genetic group, parity of the doe and sex of the bunny had slight effects only. The low to high heritability estimates, genetic and phenotypic correlations of body weights are the indication for improvement of body weights by appropriate breeding plans.

Published: April 2017

Follicle stimulating hormone (FSH) bond with the extracellular domain of the FSH receptor (FSHR) stimulates a cascade of the intracellular process that leads to folliculogenesis. This study aimed to elucidate the effects of FSHR polymorphism of its structure and function on Bos taurus through computational technology. The FSHR sequences were retrieved from Genebank. The polymorphism was identified using alignment analysis and the 3D structure of the FSHR was done by Swiss models. Results showed that FSHR of Bos taurus has three polymorphisms that located at amino acid residues 18th to 259th. The polymorphisms may alter its ability to bind with FSH. Molecular docking analysis indicated that all variant of FSHR potentially changes the pattern and affinity binding into FSH that may have an impact on reproduction status of Bos taurus. The study is a warrant for further investigation to explore biomarker of cattle reproduction status based on FSHR gene.
Assessing the Discrimination and Calibration of the Ontario Domestic Assault Risk Assessment in Switzerland
Authors: Gerth Juliane , Rossegger Astrid , Bauch Elisabeth , Endrass Jérôme
Published: April 2017

Intimate partner violence (IPV) is a major public health issue; worldwide, almost 1 in 3 women is affected. Police involvement in IPV cases has substantially increased because of “proarrest” and “procharging” policies and the enforcement of laws protecting victims of domestic violence. In the course of these changes, several front-line instruments have been developed to structure police risk assessment and decision-making strategies in such cases. One of those is the Ontario Domestic Assault Risk Assessment (ODARA). To investigate its validity in a Swiss police setting, a total cohort of male IPV offenders was retrospectively assessed for a fixed time at risk of 5 years. The recidivism base rate was 32% when recidivism was defined as subsequent police-registered IPV. Although ODARA scores were significantly correlated with IPV recidivism, they showed poor discrimination and calibration. Despite comparable base rates of recidivism, the Zurich sample scored significantly higher on the ODARA than the development sample. This mismatch of the expected and observed recidivism rates resulted in an overestimating of risk, especially in the two highest risk bins. Several reasons for those deviations, such as level of intervention, victim’s reporting behavior, and the dynamic nature of IPV, are discussed.
Propriedades verbais em estruturas nominais e nominalizadas na língua Tenetehára (Tupí-Guaraní)
Authors: Castro Ricardo Campos , Camargos Quesler Fagundes
Published: April 2017

Neste artigo, temos por objetivo demonstar que  língua Tenetehára (Tupí-Guaraní) projeta propriedades verbais em estruturas nominalizadas. Tal fato demonstra que há um paralelismo formal entre verbos e nomes. Com base nesta hipótese, mostraremos que as codificações associadas tipicamente a verbos ocorrem em sintagmas nominais. Mais precisamente, propomos que os sintagmas nominais recebem morfologias funcionais capazes de codificar categorias de tempo e de aspecto. Para isso, focalizamos principalmente  em processos de nominalizações que se dão por meio dos morfemas {-haw}, {-har}, {-ma’e}, {-pyr} e {emi-}.
Los verbos ditransitivos en mazahua
Authors: Mora-Bustos Armando
Published: April 2017

Los verbos ditransitivos, en el mazahua, expresan un tema y un recipiente, el cual es correferente con un sufijo de dativo que se codifica en el verbo. Sintácticamente, las relaciones gramaticales que se despliegan en un verbo de este tipo son: sujeto, objeto directo y objeto indirecto. El repertorio de morfemas que codifican al recipiente/dativo y al objeto/paciente es muy amplio. En esta lengua no se pueden codificar morfológicamente al mismo tiempo el sufijo del tema y del recipiente; en caso de que coaparezcan estos participantes se expresa el recipiente. Las construcciones ditransitivas con verbos de transferencia exhiben un alineamiento indirectivo (T/P=R). El tema y el paciente tienen una configuración morfológica similar y el recipiente una diferente. Finalmente, en un conjunto específico de verbos, generalmente flexionados en tercera persona codifican objetos simétricos, en consecuencia, presentan un alineamiento neutral (R=T).

Authors: Vasconcelos Eduardo Alves , Silva Sâmela Ramos da
Published: April 2017

O livro de Eunice Dias de Paula apresenta uma análise pouco comum de línguas indígenas brasileiras. Nessa análise não encontramos a tradicional descrição gramatical, nem a discussão tipológica. Por isso, é importante situar o leitor em outra perspectiva. Eunice de Paula analisa a língua dos Apyãwa colocando a comunidade de fala em primeiro plano, seguindo os pressupostos de Dell Hymes (1974, 1986). Nessa proposta, as estruturas linguísticas são resultantes de princípios básicos que norteiam a comunidade de fala, ou seja, identificar esses princípios básicos que regulam ou promovem as interações linguísticas nos permite compreender as estruturas da língua e, principalmente, porque as línguas se diferenciam. No caso dos Apyãwa, já adiantando a conclusão da autora, a cortesia e a gentileza são expressões primordiais desse povo, marcadas intrinsecamente na língua, seja nas saudações cotidianas, seja nas marcas linguísticas presentes nas narrativas míticas, seja nos cantos rituais. Em todos esses eventos, o comum é uma relação de gentileza e cortesia com outro Apyawã, com os espíritos dos antepassados ou com os Axyga, Espíritos que fazem parte da cosmologia dos Apyãwa e os acompanham, por exemplo, na construção e manutenção da Takãra.

Introduction. Acute postoperative pain continues to be a dilemma to patients and clinicians.Aim. To define the efficacy, tolerability and pharmacokinetics of paracetamol and ketoprofen in patients after the abdominal aortic surgery. Setting and design in University hospital – intensive therapy unit (clinical part), clinical pharmacy and biopharmacy unit (biochemical part), and pharmaceutical company (statistical part). Prospective randomized study.Material and Methods. 40 adult patients (50–84 years) undergoing abdominal aortic surgery were randomized equally into two groups. After extubation the patients in group 1 (G1) were administered a 1 g paracetamol infusion, and in group 2 (G2) – a 100 mg ketoprofen infusion, both within 15 minutes. All the patients received an epidural infusion of bupivacaine with fentanyl. The following parameters were recorded: mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), plasma concentration of paracetamol and ketoprofen. Postoperative pain was assessed with the visual analogue scale (VAS).Results. The mean values of the MAP, HR and CVP were within normal limits in the both groups. No significant differences were noticed in the assessment of postoperative pain and total use of an opioid. The mean therapeutic plasma concentration of paracetamol and ketoprofen remained up to 180 minutes and up to 120 minutes, respecively.Conclusions. The study enabled us to conclude that intravenous paracetamol as well as ketoprofen have good effectiveness and tolerability. There is no need to modify dosage of these drugs to elderly patients. After paracetamol infusion the therapeutic plasma concentration remains longer than after the ketoprofen infusion.

Aim. The aim of the study was to assess oral health in school‑age children on the basis of subjective and objective judgement, based on selected indicators.Material and Methods. The study included students aged 10–13 years of primary and junior‑high schools in the Mid Eastern region of Wielkopolska. Oral hygiene assessment was based on a prepared subjective questionnaireas well as on the basis of indicators: API P1.I, GI, including the sex of children.Results. Of the 161 children of school age, most of them, as many as 145 showed attention to oral health, brushing teeth twice a day; some of them apply additional measures for oral hygiene – 39 children. In both sexes there were no deviations indicators examined. Between gender showed no difference, as confirmed statistically.Conclusions. Oral hygiene in children with high health awareness rated positively, it should be emphasized that despite noninvasiveness the research group of respondents accounted for a small percentage of the children invited to the study, which points the need to undertake educational activities on a larger scale.

Published: April 2017

Blue rubber bleb nevus syndrome (BRBNS) is an uncommon condition presenting with multiple cutaneous and visceral vascular malformations, predominantly in the gastrointestinal (GI) tract. Typical skin lesion consists of a blue, soft tumor of a rubber like cohesiveness, that is easily compressible and refills slowly on release of pressure. The GI lesions are more clinically relevant, as they may induce chronic bleeding or even life threatening massive hemorrhages.

Intracrinology and gastric cancer
Authors: Frycz Bartosz Adam , Jagodziński Paweł Piotr
Published: April 2017

Overall incidence of gastric cancer (GC) in most populations is approximately two times higher in men than women. Therefore, steroid hormones are suspect to play a role in gastric carcinogenesis. Large amounts of steroid hormones in postmenopausal women and older men are synthesized in peripheral tissues through enzymatic conversion of blood derived precursors into active estrogens and androgens in so called, intracrine mechanism. Moreover, abnormal expression of genes encoding steroidogenic enzymes was shown in numerous malignant tumors including GC. These abnormalities can be associated with deregulated production of steroid hormones in gastric tissue and thus affect the risk of GC. For that reason this short review aims to summarize the current knowledge about the expression of genes involved in metabolism of steroid hormones in normal and malignant gastric mucosa and thus, estimate the potential of these tissues to intracrine synthesis of steroid hormones. This findings could be useful in understanding the role of above mechanism in GC and could help to find therapeutic approaches in future.

Auto-aggression can be defined as all actions that aim to inflict mental or physical harm to oneself. It can be caused by a dysfunction of the self-preservation instinct, which can manifest in life-threatening self-mutilation tendencies. Auto-aggression can also be one of the symptoms of psychiatric or emotional dysfunctions such as borderline personality disorder, psychopathy or schizophrenia. A dental appointment, being usually a source of great stress, can induce certain auto-aggressive behaviors as well as dental examination can show some lesions or abnormal changes of anatomical structures in the oral cavity which should be thoroughly examined and treated multidisciplinary according to patient’s behavior.
FILOSOFIA E TEOLOGIA FRENTE AO DESAFIO DO PENSAMENTO PÓS-MODERNO
Authors: Oliveira Manfredo Araújo de
Published: April 2017

Os pensadores pós-modernos partem da “virada linguística” da filosofia contemporânea e se baseiam, sobretudo, na segunda fase desta reviravolta, caracterizada por uma crítica radical ao ideal de uma linguagem única e universal. Consequentemente toda pretensão de articulação de uma teoria do real em seu todo implicaria num sistema fechado, totalitário. O artigo pretende confrontar-se com a unilateralidade da antropologia aqui pressuposta para mostrar que tanto a filosofia como a teologia são saberes abrangentes sem que isto implique em sistema fechado: a filosofia considera seus objetos a partir de estruturas que são constitutivas para o ser em seu todo e para cada um de seus campos e a teologia tem como tarefa explicitar o sentido da totalidade do real a partir da ação livre de Deus que constrói seu Reino na história humana rumo a uma realização definitiva.
À ESCUTA DA PALAVRA
Authors: Editorial .
Published: April 2017

Estamos celebrando este ano o 50° aniversário da Constituição Dogmática Dei Verbum (DV) sobre a Revelação Divina. Foi uma das constituições que mais ocupou a aula Conciliar. Começou a se discutir um mês depois do início do Concílio (14/11/1962) e só foi promulgada vinte dias antes de sua finalização (18/11/1965). Na verdade, queria-se falar sobre a revelação, e de fato se fez, mas o caminho não podia ser outro que o da Palavra, pois a revelação de Deus alcança sua plenitude e sua mediação absoluta na Palavra feita carne, Jesus Cristo (cf. DV 2).

Published: April 2017

Background: Lynch syndrome, the most frequent form of hereditary colorectal cancer and involves mutations in mismatch repair genes. The aim of this study was to identify mutations in MSH6 from 97 subjects negative for mutations in MLH1 and MSH2. Methods: By direct sequencing, we identified 27 MSH6 variants, of which, nine were novel. To verify the pathogenicity of these novel variants we performed in silico and segregation analyses. Results: Three novel variants were predicted by in silico analysis as damaging mutations and segregated with the disease phenotype. While, a novel frameshift deletion variant that was predicted to yield a premature stop codon, did not segregate with the LS phenotype in 3 of 4 cases in the family. Interestingly, another frame-shift variant identified in this study, already described in the literature, also did not segregate with the LS phenotype in 1 of 2 affected subjects in the family. In all affected subjects of both families, no mutation was detected in other MMR genes. Therefore, it is expected that within these families other genetic factors contribute to the disease either alone or in combination with MSH6 variants. Conclusion: We conclude that caution should be exercised in counseling for MSH6-associated LS family members.

Primary and secondary oil recovery from naturally fractured oil-wet carbonate reservoirs is very low. Enhanced oil recovery (EOR) from these reservoirs by use of surfactants to alter the wettability and reduce the interfacial tension (IFT) has been extensively studied for many years, but there are still many questions regarding the process mechanisms, surfactant selection and testing, experimental design, and, most importantly, how to scale up the laboratory results to the field. Therefore, the primary objective of this study was to determine the effect of scale on the oil recovery from cores with different dimensions under low-IFT conditions. There was a particular need to perform experiments by use of cores with larger horizontal dimensions because nearly all previous experiments have been performed in cores with a small diameter, typically 3.8 cm. We adapted and modified the experimental method used for traditional static-imbibition experiments by flushing out fluids surrounding the cores periodically to better estimate the oil recovery, including the produced emulsion. We used microemulsion-phase-behavior tests to develop surfactant formulations used in this study. These surfactants gave ultralow IFT at optimum salinity and good aqueous stability. Although we used ultralow-IFT (approximately 0.002 dynes/cm) formulations for most of the experiments, we also performed tests at low IFT (approximately 0.3 dynes/cm) for comparison. A second major objective of this study was to develop a simple analytical model to predict the oil recovery as a function of vertical- and horizontal-fracture spacing, rock properties, and fluid properties. The model and experimental data were found to be in good agreement considering the many simplifications made to derive the model. The scaling implied by the model is significantly different from the traditional scaling groups in the literature. The model is useful for both interpreting the experiments and for scaling the results from the laboratory to the field.
Fiber Technology Improves Cement Bonding and Eliminates Sustained Casing Pressure
Authors: Eulberg J. , Hudson M.
Published: April 2017

One of the primary challenges of cementing and achieving effective zonal isolation is removing nonaqueous drilling fluid from the wellbore. Microdebonding of the cement sheath is a significant risk to overall well integrity, potentially leading to sustained casing pressure and health, safety, and environment (HSE) hazards. Field applications of a new fiber technology, designed with an optimized surfactant and mutual solvent package, have provided improved cement evaluation logs. Such trials also reduced or eliminated sustained casing pressure.

This novel application of fiber technology in weighted spacers ahead of cement placement has been tested and evaluated with success. Modified rheometer rotors were among several new techniques developed to identify the efficacy of these cement spacer packages. These tests provide greater insight into fiber, surfactant, and mutual solvent performance, and have been validated in the field with ultrasonic and acoustic cement evaluation log results.

Detailed laboratory analysis suggests superior effectiveness of the fiber, surfactant, and mutual solvent design. These preliminary results established the confidence to pursue a field trial on a number of development wells in an unconventional liquids play.

Cement evaluation logs confirmed that the new technique successfully reduced microdebonding. Additionally, sustained casing pressure was significantly reduced, indicating that the log response correlates to a tangible improvement in well integrity.

The novel use of fiber technology considerably improves the surface cleaning effectiveness of cement spacer package. Additionally, new laboratory testing procedures enhance our understanding of surfactant package function. Successful laboratory results were validated by field applications that reduced the microannulus in sample wells and minimized sustained casing pressure.
Assessing Cybersecurity Risk for Oil & Gas Mergers and Acquisitions
Authors: Hosseini Kayvon , Paul Donald L.
Published: April 2017

This paper presents a cybersecurity risk assessment guide for mergers and acquisitions (M&A) in the oil and gas industry. The mechanisms used for assessing cyber risk are technology neutral and developed around an organization's security culture, information systems, and operating infrastructure as they apply to the M&A process. Assessing a security infrastructure includes any connections between information technology and operational technology systems. Security considerations relating to the integration of acquired operating and information system assets are also factored into the approach. For mergers, we present six open-ended questions that are linked to specific cybersecurity functions and corresponding domains. Each domain includes industry best practices for acquirers to understand the relative maturity of a target company's cybersecurity program. Asset acquisitions require a less-comprehensive approach that focuses on four relevant areas of risk. The assessment presented in this paper can be used by companies operating across the oil and gas supply chain.
Surface Treatment for Sand Reduces Airborne Dust

Published: April 2017

As of June 23, 2016 the Occupational Safety and Health Administration (OSHA) final rule on Occupational Exposure to Respirable Crystalline Silica took effect. This final rule establishes a new worker permissible exposure limit to airborne silica dust of 0.05 mg/m3 as an 8-hour time-weighted average. It also includes other provisions to protect employees, such as requirements for exposure assessment, hazard communication, engineering controls, respiratory protection, medical surveillance, and recordkeeping. The hydraulic fracturing industry must meet the new requirements by June 23, 2021 which gives an excellent opportunity for employers to develop and implement emerging technologies for crystalline silica control.

Herein, we report a newly developed cost-effective strategy for dust control, in which a chemical is easily sprayed onto fracturing sand. This coating will not only reduce the occurrence of airborne dust during fracturing operations, but will also improve other properties including the compressive strength of the sand and improve the proppant pack conductivity.

From sand mining, through processing up to the final delivery at the frac blender augers, numerous points of silica exposure have been identified. Several attempts have been made to implement engineering controls to limit silica exposure at the fracturing site, e.g. dust collection devices at fracturing sand units, where sand is pneumatically loaded from bulk trucks. However, it is reported that workplace concentration of airborne respirable silica exceeds the permissible exposure limit by 20 times or more.

This chemically inert technology can be applied by simply spraying the coating onto fracturing sand at concentrations as low as 0.05% by weight of proppant, with a reduction of 90% v/v of airborne dust observed through sand blast testing. Additionally crush resistance tests performed at multiple stresses have consistently shown that ~20 to 30% w/w less fines are generated when compared to untreated sand.

A field trial of this sand coating technology will show significant reduction in airborne crystalline silica at multiple test locations on a fracturing site during normal operations. It will be shown that the treated sand is free to flow and easy to operate without the use of special equipment.

This new technology in combination with already implemented PPE best practices and engineering controls for dust mitigation, such as dust/vacuum collection devices, etc., will help to enable full compliance with the new set of safety requirements established by OSHA.
High-Temperature Imbibition for Enhanced Recovery from Diatomite
Authors: Kim Tae Wook , Kovscek Anthony
Published: April 2017

It is difficult to produce oil from diatomite due to unique rock properties such as low permeability, high porosity, fine laminations, and fractures. Steam injection is a promising enhanced oil recovery method for diatomite, but the generation and injection of steam may lead to large energy cost and, potentially, well failures. Injection of hot water instead of steam provides a means to decouple pressure and temperature while still achieving the benefits of thermal recovery. This study investigates and compares oil recoveries from fractured diatomite cores (1.5 ″, 3.5 ″, and 5 ″diameter) using hot water and steam. Both hot water and steam injection at 200 °C were applied under spontaneous and forced imbibition conditions. Cores from two different reservoirs (A and B) were used. The B reservoir oil and brine formation were adopted for all cases. Synthetic steam boiler feed was used to create hot water and steam. An X-ray CT scanner was used to visualize in-situ phases saturations and characterize the porosity/oil saturation distribution. Wettability alteration toward water-wet conditions was observed clearly at elevated temperature (200 °C) for all cores. The Amott index, Iw, for hot water and steam injection around 200 °C with reservoir A conditions were 0.41 (A#1) and 0.36 (A#2), respectively. The final oil recovery from A cores at 45 °C and 200 °C were 62- 64 % and 78- 82 % OOIP, respectively. The A reservoir whole core with 5 ″ diameter at 45 °C showed greater oil recovery from spontaneous imbibition than the 1.5 ″ diameter core. The Iw and final oil recovery from core A with both steam and hot water injection at 200 °C was nearly identical. With B core, the Iw increased from 0.28 (45 °C, water) to 0.34 (200 °C, steam). The Iw of B core was equal to 0.33 after both hot water injection and steam injection. The final oil recoveries of both hot water and steam at 200 °C showed 76 % and 80 % OOIP, respectively. Both in situ visualization and effluent analysis shows that rock dissolution and fines migrations contribute the evolution of fracture and pore networks within the core. Therefore, results suggest that hot water provides the benefits of thermal recovery, in some regards, while decoupling pressure and temperature.
