Published: December 2017

ABSTRACTOEl 80-90% de los cuerpos extraños ingeridos voluntaria o accidentalmente se evacuan espontáneamente, sin embargo se requiere de una endoscopia terapéutica en un 10-20% de los casos y de cirugía en menos del 1% de los mismos.ObjetivoAnalizar las características de los pacientes asistidos por ingesta de cuerpo extraño en el Departamento de Emergencia del Hospital Maciel y llegar al diseño de guías de actuación en el contexto de un equipo multidisciplinario.ResultadosNuestra serie constó de 31 consultas por ingesta de cuerpo extraño. El 52% provenía de instituciones psiquiátricas y el 42% eran reclusos, un caso no pertenecía a ninguna de las 2 categorías. El 27,5% de las consulta se habían producido en las primeras 24hs desde la ingesta, el 24% de las ingestas se habían producido con más de una semana desde la ingesta y el resto oscilaba entra ambos tiempos evolutivos En cuanto a la conducta, en 12 casos se otorgó el alta sin mediar conducta activa endoscópica y/o quirúrgica. Se realizó una FGC en el 64% de los casos en los cuales se constató radiológicamente la ingesta de un cuerpo extraño, siendo efectivamente terapéuticas para la extracción de objetos a nivel gastroduodenal en el 67% de las mismas. De las 28 consultas por ingesta de CE 6 pacientes (21%) fueron operados. En 5 de ellos por falla de la extracción endoscópica, el restante se presentó como una peritonitis aguda. La ingesta de CE representa una patología de consulta frecuente en el Departamento de Emergencia. El manejo del mismo se realiza mediante un abordaje multidisciplinario que en el caso de nuestra serie mostró porcentajes de extracción endoscópica efectiva cercana al 70% comparable con otras series internacionales. El análisis de las características de la población analizada y el análisis de la evidencia científica publicada nos permite plantear un protocolo de actuación.How to cite this articleTrostchansky J, Masaferro G.

Modeling the effects of tree species and incubation temperature on soil's extracellular enzyme activity in 78-year-old tree plantations
Authors: Zhou Xiaoqi , Wang Shen S. J. , Chen Chengrong 
Published: December 2017

Abstract. Forest plantations have been widely used as an effective measure for increasing soil carbon (C), and nitrogen (N) stocks and soil enzyme activities play a key role in soil C and N losses during decomposition of soil organic matter. However, few studies have been carried out to elucidate the mechanisms behind the differences in soil C and N cycling by different tree species in response to climate warming. Here, we measured the responses of soil's extracellular enzyme activity (EEA) to a gradient of temperatures using incubation methods in 78-year-old forest plantations with different tree species. Based on a soil enzyme kinetics model, we established a new statistical model to investigate the effects of temperature and tree species on soil EEA. In addition, we established a tree species–enzyme–C∕N model to investigate how temperature and tree species influence soil C∕N contents over time without considering plant C inputs. These extracellular enzymes included C acquisition enzymes (β-glucosidase, BG), N acquisition enzymes (N-acetylglucosaminidase, NAG; leucine aminopeptidase, LAP) and phosphorus acquisition enzymes (acid phosphatases). The results showed that incubation temperature and tree species significantly influenced all soil EEA and Eucalyptus had 1.01–2.86 times higher soil EEA than coniferous tree species. Modeling showed that Eucalyptus had larger soil C losses but had 0.99–2.38 times longer soil C residence time than the coniferous tree species over time. The differences in the residual soil C and N contents between Eucalyptus and coniferous tree species, as well as between slash pine (Pinus elliottii Engelm. var. elliottii) and hoop pine (Araucaria cunninghamii Ait.), increase with time. On the other hand, the modeling results help explain why exotic slash pine can grow faster, as it has 1.22–1.38 times longer residual soil N residence time for LAP, which mediate soil N cycling in the long term, than native coniferous tree species like hoop pine and kauri pine (Agathis robusta C. Moore). Our results will be helpful for understanding the mechanisms of soil C and N cycling by different tree species, which will have implications for forest management.
Money, Relativism, and the Post-Truth Political Imaginary
Authors: Goodstein Elizabeth S. 
Published: December 2017

ABSTRACT
Walter Benjamin's warning against unphilosophical “astonishment that the things we are experiencing are ‘still’ possible” has new urgency in the face of real estate developer and reality-show host Donald Trump's surprise victory in the presidential election of 2016. Philosopher, sociologist, and cultural theorist Georg Simmel's 1900 magnum opus, the Philosophy of Money, provides valuable orientation at a moment when the expectation that public discourse must be oriented by norms of truth and accuracy is under siege—not least by those who ascended to power openly denigrating the value of expertise and the specialized knowledge long regarded as essential to modern government. Trump has an instinctive grasp of Simmel's decisive insight that “money is the strongest and most immediate symbol” of the cynical truism that “the only absolute is the relativity of things.” Situating philosophy at the limits of disciplinary ways of knowing, the Philosophy of Money develops a modernist, performative strategy of thought that turns relativity into a philosophical resource. It can help us to counter the dissolution of the ideal of veracity in an era of absolutized marketing by disentangling thought from narratives of rational progress that obscure its opposite and interrogating the limitations of the professionalized ordering of knowledge practices in which expertise continues to be produced and maintained. Simmel's strategy for embracing the fragmentation, multiplicity, and uncertainty of human experience may thereby help us address the complexity and ambiguity of a historical situation growing increasingly surreal as techno-scientific progress goes hand in hand with post-truth politics.
Feminist Critique and the Realistic Spirit
Authors: Zerilli Linda M. G. 
Published: December 2017

ABSTRACTContemporary debates over the future of critique, feminist or otherwise, tend to neglect if not perpetuate a reliance on the philosophical tradition, with its disdain for the contingent and indifference to local audiences. If critique is to be realistic, as distinguished from realist or antirealist as the philosophical tradition has defined those terms, it must begin by clarifying the nature and extent of this reliance and begin to develop alternatives. Such an idea of critique would begin by questioning received notions of the relationship between theory and practice, which I argue are unduly inflected by philosophical prejudices. Theory should not be understood as a primarily epistemological or methodological enterprise whose task is to justify the basis of critique. Instead, theory should be conceived, with the rhetorical tradition, as a world-creating, first-order practice that gives meaning and significance to the human commons.
Grace Gilchrist's Childish Jealousy and Bernard Shaw's Idiotic Thoughtlessness
Authors: Hellman Jesse M. 
Published: December 2017

ABSTRACT
Grace Gilchrist was one of the young women whom Bernard Shaw knew and befriended in the 1880s. What is known of her comes mostly from Shaw's Diary and a few letters, and pertains to the jealousy she showed in regard to other young women in their circle. Shaw could stir up jealousy while at the same time think of himself as innocent. This article shows that in Grace he had met someone particularly susceptible, as can be seen through her own history as well as that of her family. Grace, her mother, and Walt Whitman may have even played some part in Shaw's inspiration for Man and Superman.
Determination of Monensin in Bovine Tissues: A Bridging Study Comparing the Bioautographic Method (FSIS CLG-MON) with a Liquid Chromatography-Tandem Mass Spectrometry Method (OMA 2011.24)

Published: December 2017

Abstract
The U.S. Department of Agriculture, Food Safety Inspection Service regulatory method for monensin, Chemistry Laboratory Guidebook CLG-MON, is a semiquantitative bioautographic method adopted in 1991. Official Method of AnalysisSM (OMA) 2011.24, a modern quantitative and confirmatory LC-tandem MS method, uses no chlorinated solvents and has several advantages, including ease of use, ready availability of reagents and materials, shorter run-time, and higher throughput than CLG-MON. Therefore, a bridging study was conducted to support the replacement of method CLG-MON with OMA 2011.24 for regulatory use. Using fortified bovine tissue samples, CLG-MON yielded accuracies of 80–120% in 44 of the 56 samples tested (one sample had no result, six samples had accuracies of &gt;120%, and five samples had accuracies of 40–160%), but the semiquantitative nature of CLG-MON prevented assessment of precision, whereas OMA 2011.24 had accuracies of 88–110% and RSDr of 0.00–15.6%. Incurred residue results corroborated these results, demonstrating improved accuracy (83.3–114%) and good precision (RSDr of 2.6–20.5%) for OMA 2011.24 compared with CLG-MON (accuracy generally within 80–150%, with exceptions). Furthermore, χ2 analysis revealed no statistically significant difference between the two methods. Thus, the microbiological activity of monensin correlated with the determination of monensin A in bovine tissues, and OMA 2011.24 provided improved accuracy and precision over CLG-MON.
Unanticipated discovery of two rare gastropod molluscs from recently located hydrothermally influenced areas in the Okinawa Trough

Published: December 2017

BackgroundThe deep-sea hydrothermal vent is one of the most ‘extreme’ environments in the marine realm. Few species are capable of inhabiting such ecosystems, despite extremely high productivity there supported by microbial chemosynthesis, leading to high biomass and low species richness. Although gastropod molluscs are one of the main constituents of megafaunal communities at vent ecosystems, most species belong to several typical families (e.g., Provannidae, Peltospiridae, Lepetodrilidae) specialised and adapted to life at vents.MethodsDuring recent surveys of Okinawa Trough hydrothermal vent systems, two snails atypical of vent ecosystems were unexpectedly found in newly discovered hydrothermally influenced areas. Shell and radular characteristics were used to identify the gastropods morphologically.ResultsOne species was a vetigastropod, the calliostomatidTristichotrochus ikukoae(Sakurai, 1994); and the other was a caenogastropod, the muricidAbyssotrophon soyoae(Okutani, 1959). Both gastropods were previously only known from regular non-chemosynthetic deep-sea and very rare—only two definitive published records exist forT. ikukoaeand three forA. soyoae. The radula formula ofTristichotrochus ikukoaeis accurately reported for the first time and based on that it is returned to genusOtukaia. For both species, barcode sequences of the cytochromecoxidase I (COI) gene were obtained and deposited for future references.DiscussionThese new records represent the second record of calliostomatids from vents (third from chemosynthetic ecosystems) and the third record of muricids from vents (tenth from chemosynthetic ecosystems), and extend the distribution of both species to the southwest. Neither family has been recorded at chemosynthetic ecosystems in the western Pacific. Both were from weakly diffuse flow areas not subject to high temperature venting but were nevertheless associated with typical vent-reliant taxa such asLamellibrachiatubeworms andBathymodiolusmussels. These new records show that these species are capable of tolerating environmental stress associated with weak hydrothermally influenced areas, despite not being vent endemic species, adding to the list of known vent/non-vent species intersections. This signifies that such weakly influenced areas may provide key habitats for them, and that such areas may play a role in the evolution of biological adaptations to ‘extreme’ chemosynthetic ecosystems.

AbstractDas cyclische Depsipeptid FR900359 (FR), isoliert aus der tropischen Pflanze Ardisia crenata, zeigt starke und selektive Inhibierung von Gq‐Proteinen. Dadurch ist es sowohl für die Erforschung Gq‐abhängiger Prozesse interessant als auch ein vielversprechender Arzneimittelkandidat. Gq‐Inhibierung ist ein neuer Wirkmechanismus für Abwehrstoffe und entscheidend für die ökologische Funktion von FR, wie durch In‐vivo‐Experimente an Mäusen, Affinität zu Gq‐Proteinen von Insekten und Toxizitätsstudien an Insekten gezeigt wurde. Die Sequenzierung des unkultivierten Endosymbionten von A. crenata führte zur Entdeckung des nichtribosomalen Peptidsynthetasegenclusters von FR (frs). Wir präsentieren hier ein Modell der Biosynthese von FR, unterstützt durch bioinformatische und In‐vitro‐Enzymstudien und das neue Derivat AC‐1, welches Flexibilität der Starter‐Kondensierungsdomänen von FR beweist. Expression der frs‐Gene in E. coli führte erstmals zu heterologen Produktion von FR in einem kultivierbaren bakteriellen Wirt.
Chitosan/MCM‐41 nanocomposites for efficient beryllium separation
Authors: Morsi Rania E. , Elsherief Mohamed A. , Shabaan M. , Elsabee M. Z. 
Published: December 2017

ABSTRACTChitosan nanoparticles (Ch NPs) with individual particles 10–30 nm in size and average aggregate sizes of 240 nm were prepared via ionic gelation. Ordered mesoporous Mobil Composition of Matter No. 41 (MCM‐41) with a surface area of 1590 m2/g was prepared via a sol–gel method. The nanocomposites were prepared via the in situ dispersion of MCM‐41 in chitosan followed by ionic gelation with a multivalent anion to produce MCM‐41‐impregnated Ch NPs or via the mixture of dispersed MCM‐41 with preprepared Ch NPs to produce Ch NPs supported on MCM‐41. The beryllium‐uptake efficiency was studied with different pH values, contact times, and initial Be(II) concentrations. The maximum achieved uptake efficiencies of the nanocomposites (95% and 96%) were superior to that of MCM‐41 (38%) and higher than that of Ch NPs (90%). The nanocomposite formulas facilitated post‐treatment separation while maintaining a high beryllium‐uptake efficiency. The Be(II)‐uptake process for all of the materials followed the pseudo‐second‐order kinetic model and both the Langmuir and Freundlich isotherms. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

Development and use of a piggyBac‐based jumpstarter system in Drosophila suzukii
Authors: Chu Fu‐Chyun , Klobasa William , Grubbs Nathaniel , Lorenzen Marcé D. 
Published: December 2017

AbstractSpotted wing drosophila, Drosophila suzukii, is an invasive pest that primarily attacks fresh, soft‐skinned fruit. Although others have reported successful integration of marked piggyBac elements into the D. suzukii genome, with a very respectable transgenesis rate of ∼16%, here we take this work a step further by creating D. suzukii jumpstarter strains. These were generated through integration of a fluorescent‐marked Minos element carrying a heat shock protein 70‐driven piggyBac transposase gene. We demonstrate that there is a dramatic increase in transformation rates when germline transformation is performed in a transposase‐expressing background. For example, we achieved transformation rates as high as 80% when microinjecting piggyBac‐based plasmids into embryos derived from one of these D. suzukii jumpstarter strains. We also investigate the effect of insert size on transformation efficiency by testing the ability of the most efficient jumpstarter strain to catalyze integration of differently‐sized piggyBac elements. Finally, we demonstrate the ability of a jumpstarter strain to remobilize an already‐integrated piggyBac element to a new location, demonstrating that our jumpstarter strains could be used in conjunction with a piggyBac‐based donor strain for genome‐wide mutagenesis of D. suzukii.
Estimating the DINA model parameters using the No‐U‐Turn Sampler
Authors: da Silva Marcelo A. , de Oliveira Eduardo S. B. , von Davier Alina A. , Bazán Jorge L. 
Published: December 2017

AbstractThe deterministic inputs, noisy, “and” gate (DINA) model is a popular cognitive diagnosis model (CDM) in psychology and psychometrics used to identify test takers' profiles with respect to a set of latent attributes or skills. In this work, we propose an estimation method for the DINA model with the No‐U‐Turn Sampler (NUTS) algorithm, an extension to Hamiltonian Monte Carlo (HMC) method. We conduct a simulation study in order to evaluate the parameter recovery and efficiency of this new Markov chain Monte Carlo method and to compare it with two other Bayesian methods, the Metropolis Hastings and Gibbs sampling algorithms, and with a frequentist method, using the Expectation–Maximization (EM) algorithm. The results indicated that NUTS algorithm employed in the DINA model properly recovers all parameters and is accurate for all simulated scenarios. We apply this methodology in the mental health area in order to develop a new method of classification for respondents to the Beck Depression Inventory. The implementation of this method for the DINA model applied to other psychological tests has the potential to improve the medical diagnostic process.
Coffee‐Waste Templating of Metal Ion‐Substituted Cobalt Oxides for the Oxygen Evolution Reaction
Authors: Yu Mingquan , Chan Candace K. , Tüysüz Harun 
Published: December 2017

AbstractA facile and scalable method using coffee waste grounds as a hard template has been developed to fabricate nanostructured Co3O4 for the oxygen evolution reaction (OER). Co3O4 incorporating metals with different valences (M/Co=1:4; M=Cu, Ni, Fe, Cr, and W) were also prepared with similar sheet‐like structures comprising nanosized crystallites. After detailed characterization by X‐ray diffraction, electron microscopy, and nitrogen sorption, the oxides were employed as OER electrocatalysts. Substitution of octahedral and tetrahedral sites of the spinel structure with divalent and trivalent transition metals (Cu, Ni, Fe, and Cr) increased the activity of Co3O4 for the OER, whereas incorporation of hexavalent W led to formation of a second crystal phase and significantly higher electrocatalytic performance. Furthermore, this method is easily scaled up for mass production of Co3O4 with the same nanostructure, which is highly desirable for large‐scale application.
Biomechanical effects of trees in an old‐growth temperate forest

Published: December 2017

AbstractThe role of biomechanical effects of trees (BETs) in ecosystem and landscape dynamics is poorly understood. In this study, we aim to (i) describe a widely applicable methodology for quantifying the main BETs in soil, and (ii) analyze the actual frequencies, areas and soil volumes associated with these effects in a mountain temperate old‐growth forest.The research took place in the Boubínský Primeval Forest in the Czech Republic; this forest reserve, predominated byFagus sylvaticaL. andPicea abies(L.) Karst., is among the oldest protected areas in Europe. We evaluated the effects of 4000 standing and lying trees in an area of 10.2 ha from the viewpoint of the following features: tree uprooting, root mounding, bioprotection, trunk baumsteins (rock fragments displaced by trunk growth), root baumsteins, stump hole infilling, trunk and root systems displacements, depressions formed after trunk fall, stemwash, and trunkwash.BETs were recorded in 59% of standing and 51% of lying dead trees (excluding the pervasive soil displacement by thickening trunks and roots and the infilling of decayed stumps). Approximately one tenth of the trees showed simultaneous bioprotective and bioerosion effects. Different tree species and size categories exhibited significantly different biomechanical effects.A bioprotective function was the most frequent phenomenon observed, while treethrows prevailed from the viewpoint of areas and soil volumes affected. The total area influenced by the BETs was 342 m2 ha−1. An additional 774 m2 ha−1were occupied by older treethrow pit‐mounds with already decayed uprooted trunks. The total volume of soil associated with the studied phenomena was 322 m3 ha−1, and apart from treethrows, volumes of the living and decaying root systems and bioprotective functions predominated. Other processes were not so frequent but still significant for biogeomorphology. Copyright © 2017 John Wiley & Sons, Ltd.
Mineralogical characteristic of ductile–brittle shear zone in the Baguamiao gold deposit, Shaanxi Province: Implication for gold mineralization
Authors: Xie Xing , Fu Yuzhen , Liu Jiajun 
Published: December 2017

The Baguamiao gold deposit in Fengxian County of Shaanxi Province is located in Fengtai polymetallic ore concentration area in the orogenic belt of West Qinling Mountain. It is a typical gold deposit under the control of brittle–ductile shear zone. The progressive deformation of brittle–ductile shear zone has been found to be closely associated with gold enrichment: the gold‐bearing sulphides pyrrhotite and pyrite are distributed along blastobedding S0 in the undeformed area, they are developed along phyllitic foliation S1 (//S0) in the slightly deformed area, along mylonitic foliation (S2#S0), or S–C foliation in the highly deformed area, and they are enriched along rheological quartz vein (S2–L) and joint quartz vein (S3) in the highly deformed and the tectonic fluid area. Researches based on electron microprobe analysis and mineral–structure–geochemistry indicate that the characteristic metamorphic mineral assemblage of the brittle–ductile shear zone is albite–biotite–sericite–chlorite–quartz–ankerite, with diagenetic and metallogenic temperatures and pressures spanning from 350 to 450 °C and from 0.12 to 0.31 GPa, respectively. In addition, greenschist facies in intermediate temperature and intermediate and low‐pressure environment is the metamorphic facies of shear zone in main period. A reconstruction of the palaeotemperature history, based on the biotite and chlorite compositional geothermometer, revealed an intermediate‐temperature phase, a high‐temperature phase, and a high‐temperature critical phase. Biotitization tends to develop towards an oxidation phase, while chloritization is characterized by development towards a reduction phase, indicating large‐scale gold enrichment and mineralization were accompanied by strong redox reactions in the ore‐forming fluid.
