Arabidopsis RabF1 (ARA6) Is Involved in Salt Stress and Dark-Induced Senescence (DIS)
Authors: Yin Congfei , Karim Sazzad , Zhang Hongsheng , Aronsson Henrik
Published: February 2017

Arabidopsis small GTPase RabF1 (ARA6) functions in endosomal vesicle transport and may play a crucial role in recycling and degradation of molecules, thus involved in stress responses. Here we have reported that complementary overexpression lines RabF1OE (overexpression), GTPase mutants RabF1Q93L (constitutively active) and RabF1S47N (dominant negative) lines show longer root growth than wild-type, rabF1 knockout and N-myristoylation deletion (Δ1−29, N-terminus) complementary overexpression mutant plants under salt induced stress, which indicates that N-myristoylation of RabF1 is indispensable for salt tolerance. Moreover, RabF1 is highly expressed during senescence and RabF1OE lines were more tolerant of dark-induced senescence (DIS) than wild-type and rabF1.
Quantity- and Quality-Based Farm Water Productivity in Wine Production: Case Studies in Germany
Authors: Peth Denise , Drastig Katrin , Prochnow Annette
Published: February 2017

The German wine sector has encountered new challenges in water management recently. To manage water resources responsibly, it is necessary to understand the relationship between the input of water and the output of wine, in terms of quantity and quality. The objectives of this study are to examine water use at the farm scale at three German wineries in Rhenish Hesse, and to develop and apply, for the first time, a quality-based indicator. Water use is analyzed in terms of wine production and wine-making over three years. After the spatial and temporal boundaries of the wineries and the water flows are defined, the farm water productivity indicator is calculated to assess water use at the winery scale. Farm water productivity is calculated using the AgroHyd Farmmodel modeling software. Average productivity on a quantity basis is 3.91 L wine per m3 of water. Productivity on a quality basis is 329.24 Oechsle per m3 of water. Water input from transpiration for wine production accounts for 99.4%–99.7% of total water input in the wineries, and, because irrigation is not used, precipitation is the sole source of transpired water. Future studies should use both quality-based and mass-based indicators of productivity.
Isolation by distance and stochastic migration in a fragmented population ofProsopis alba
Authors: Roser Leandro G. , Ferreyra Laura I. , Ewens Mauricio , Vilardi Juan C. , Saidman Beatriz O.
Published: February 2017

PREMISE OF THE STUDY:

Gene flow through dispersal of seeds and pollen is a fundamental determinant of spatial genetic structure (SGS) in natural populations of trees at different spatial scales. Within continuous populations, restrictions to gene flow should be manifested in a process of local genetic differentiation, known as isolation by distance. The present work examines the SGS of aProsopis albapopulation in a patchy region where urban, forest, and agricultural areas coexist. The analysis discussed here expands our knowledge about the processes affecting the distribution of the genetic variability in populations of disturbed landscapes.

METHODS:

Three sites with different landscape and demographic characteristics were analyzed. Seven highly variable microsatellite markers were used to survey the relevance of both isolation by distance and stochastic migration in the SGS of the population.

KEY RESULTS:

The analyses showed that (1) the genetic similarity declined with increasing geographic distance, (2) the population may be conceived as a single genetically continuous unit showing spatial differentiation as consequence of isolation by distance, rather than a structured population following the island model, and (3) there is evidence supporting a past immigration event into one of the study sites, which promoted a local pattern of genetic structure.

CONCLUSIONS:

These results indicate that in spite of the population fragmentation produced by land‐use changes,P. albamaintains the genetic cohesion and a continuous genetic structure in the analyzed area.
Complex patterns of multiple biomineralization in single‐celled plant trichomes of the Loasaceae
Authors: Ensikat Hans‐Jürgen , Mustafa Adeel , Weigend Maximilian
Published: February 2017

PREMISE OF THE STUDY:

Plants of the family Loasaceae are characterized by a usually dense indument of various trichome types, including two basically different types of mineralized, unicellular trichomes (stinging hairs or setae and scabrid‐glochidiate trichomes). Mineralized trichomes have long been known to have silicified or calcified walls, but recent studies demonstrated that trichomes of Loasaceae may also contain calcium phosphate. The current study investigates the distribution of different biominerals in the mineralized trichomes across several different taxa.

METHODS:

Plants from cultivation were studied with scanning electron microscopy including energy dispersive x‐ray analyses and element mapping.

KEY RESULTS:

The vast majority of the 31 species investigated had at least two different biominerals in their trichomes, and 22 had three different biominerals in their trichomes. Thirty of the species had calcium phosphate in their trichomes. Loasa was mostly free of silica, but contained calcium phosphate in trichome tips and barbs, whereas calcium phosphate and silica were found in representatives of other genera of the family (Blumenbachia, Caiophora, Nasa).

CONCLUSIONS:

Biomineralization is remarkably diversified between species, different trichome types and parts of the same trichome. Individual genera largely had different patterns of biomineralization. The presence of three biominerals in the trichomes of the basally branching Eucnide urens indicates either an early evolution and subsequent loss or several independent origins of multiple biomineralization. Differential biomineralization of the parts of individual, unicellular trichomes clearly indicates an extraordinary degree of physiological control over this process.
THE M DWARF ECLIPSING BINARY CU CANCRI

Spectral features, radial velocities, elemental abundance estimates, other spectral data, and BVI

C
light curves are reported for the double-M dwarf eclipsing binary CU Cancri—a good target for a radius check versus the Zero Age Main Sequence (ZAMS) due to the low component masses and corresponding very slow evolutionary expansion. The estimate of [Fe/H] is about 0.4, although continuum placement and other difficulties due to line crowding introduce the usual uncertainties for red dwarfs. Detection of the Li i
λ6707 line was attempted, with an estimated upper limit of 50 mÅ. Spectral and photometric indicators of stellar activity are described and illustrated. Other objectives were to measure the stellar radii via simultaneous velocity and light-curve solutions of earlier and new data while also improving the ephemeris by filling gaps in timewise coverage with the new velocities and eclipse data from the new light curves. The radii from our solutions agree within about 2% with those from Ribas, being slightly larger than expected for most estimates of the ZAMS. Some aspects of the red dwarf radius anomaly are briefly discussed. Evolution tracks show only very slight age-related expansion for masses near those in CU Cnc. Such expansion could be significant if CU Cnc were similar in age to the Galaxy, but then its Galactic velocity components should be representative of Population II, and they are not.
n-gon Equilibria of the Discrete
-body Problem
Authors: Minesaki Yukitaka
Published: February 2017

We prove that the discrete-time general

-body problem (d-G

BP) proposed by Minesaki can exactly trace the orbits of elliptic relative equilibrium solutions in the original general

-body problem (G

BP). These orbits include the orbits of relative equilibrium solutions that have already been discovered. Before this proof, no discrete-time system had been shown to retain the orbits of elliptic relative equilibrium solutions in

BP. d-G

BP can also precisely reproduce doubly symmetric orbits of the general

-body problem, each of which passes near a square equilibrium solution over a long time interval.
A Condensation–coalescence Cloud Model for Exoplanetary Atmospheres: Formulation and Test Applications to Terrestrial and Jovian Clouds
Authors: Ohno Kazumasa , Okuzumi Satoshi
Published: February 2017

A number of transiting exoplanets have featureless transmission spectra that might suggest the presence of clouds at high altitudes. A realistic cloud model is necessary to understand the atmospheric conditions under which such high-altitude clouds can form. In this study, we present a new cloud model that takes into account the microphysics of both condensation and coalescence. Our model provides the vertical profiles of the size and density of cloud and rain particles in an updraft for a given set of physical parameters, including the updraft velocity and the number density of cloud condensation nuclei (CCNs). We test our model by comparing with observations of trade-wind cumuli on Earth and ammonia ice clouds in Jupiter. For trade-wind cumuli, the model including both condensation and coalescence gives predictions that are consistent with observations, while the model including only condensation overestimates the mass density of cloud droplets by up to an order of magnitude. For Jovian ammonia clouds, the condensation–coalescence model simultaneously reproduces the effective particle radius, cloud optical thickness, and cloud geometric thickness inferred from Voyager observations if the updraft velocity and CCN number density are taken to be consistent with the results of moist convection simulations and Galileo probe measurements, respectively. These results suggest that the coalescence of condensate particles is important not only in terrestrial water clouds but also in Jovian ice clouds. Our model will be useful to understand how the dynamics, compositions, and nucleation processes in exoplanetary atmospheres affect the vertical extent and optical thickness of exoplanetary clouds via cloud microphysics.
Pulsational Pair-instability Model for Superluminous Supernova PTF12dam:Interaction and Radioactive Decay
Authors: Tolstov Alexey , Nomoto Ken’ichi , Blinnikov Sergei , Sorokina Elena , Quimby Robert , Baklanov Petr
Published: February 2017

Being a superluminous supernova, PTF12dam can be explained by a 56Ni-powered model, a magnetar-powered model, or an interaction model. We propose that PTF12dam is a pulsational pair-instability supernova, where the outer envelope of a progenitor is ejected during the pulsations. Thus, it is powered by a double energy source: radioactive decay of 56Ni and a radiative shock in a dense circumstellar medium. To describe multicolor light curves and spectra, we use radiation-hydrodynamics calculations of the STELLA code. We found that light curves are well described in the model with 40 M
⊙ ejecta and 20–40 M
⊙ circumstellar medium. The ejected 56Ni mass is about 6 M
⊙, which results from explosive nucleosynthesis with large explosion energy (2–3) × 1052 erg. In comparison with alternative scenarios of pair-instability supernova and magnetar-powered supernova, in the interaction model, all the observed main photometric characteristics are well reproduced: multicolor light curves, color temperatures, and photospheric velocities.
Long-period Intensity Pulsations in Coronal Loops Explained by Thermal Non-equilibrium Cycles
Authors: Froment C. , Auchère F. , Aulanier G. , Mikić Z. , Bocchialini K. , Buchlin E. , Solomon J.
Published: February 2017

In solar coronal loops, thermal non-equilibrium (TNE) is a phenomenon that can occur when the heating is both highly stratified and quasi-constant. Unambiguous observational identification of TNE would thus permit us to strongly constrain heating scenarios. While TNE is currently the standard interpretation of coronal rain, the long-term periodic evolution predicted by simulations has never been observed. However, the detection of long-period intensity pulsations (periods of several hours) has been recently reported with the Solar and Heliospheric Observatory/EIT, and this phenomenon appears to be very common in loops. Moreover, the three intensity-pulsation events that we recently studied with the Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) show strong evidence for TNE in warm loops. In this paper, a realistic loop geometry from linear force-free field (LFFF) extrapolations is used as input to 1D hydrodynamic simulations. Our simulations show that, for the present loop geometry, the heating has to be asymmetrical to produce TNE. We analyze in detail one particular simulation that reproduces the average thermal behavior of one of the pulsating loop bundle observed with AIA. We compare the properties of this simulation with those deduced from the observations. The magnetic topology of the LFFF extrapolations points to the presence of sites of preferred reconnection at one footpoint, supporting the presence of asymmetric heating. In addition, we can reproduce the temporal large-scale intensity properties of the pulsating loops. This simulation further strengthens the interpretation of the observed pulsations as signatures of TNE. This consequently provides important information on the heating localization and timescale for these loops.
Pratiques vestimentaires et expressions du genre

Published: February 2017

À partir d’une étude ethnographique comparative des pratiques vestimentaires de collégien·ne·s, ce travail rend compte des effets des contextes sociaux et scolaires sur les processus de construction du genre et sur les manières diversifiées de l’investir. L’analyse questionne les processus d’identification à un groupe du même sexe et les manières dont sont intériorisées des normes et des pratiques sexuellement différenciées et hiérarchisées. Des modèles de genre pluriels coexistent et peuvent évoluer d’un milieu scolaire à l’autre, au sein d’un même milieu et d’un groupe du même sexe. Ces variations soulignent les effets de la socialisation corporelle et des différents contextes socialisateurs dans les manières différenciées de « faire le genre ».
Le projet entrepreneurial à l’école primaire : tensions inhérentes à son intégration à la forme scolaire
Authors: Pepin Matthias
Published: February 2017

Bien qu’objet d’un discours largement incitatif à l’échelle internationale, l’introduction de l’entrepreneuriat dans le domaine éducatif ne va pas de soi. L’auteur de cet article développe l’idée selon laquelle un facteur explicatif contraignant la mise en œuvre de projets entrepreneuriaux à l’école, comme véhicules privilégiés pour y développer l’éducation entrepreneuriale, trouve sa source dans le concept de « forme scolaire ». En effet, la forme scolaire symbolise un mouvement de repli, de mise à l’écart de l’école par rapport à la société, là où les projets entrepreneuriaux représentent un mouvement d’ouverture, de réintroduction de la « vraie » vie au cœur de l’école. Les tensions qui naissent de cette rencontre entre deux logiques opposées sont au cœur du propos, illustrées par les résultats d’une recherche de doctorat en sciences de l’éducation réalisée au Québec.

Published: February 2017

L’étude des startupers ou fondateurs de start-up constitue l’objet de ce travail fondé sur une méthodologie qualitative par entretiens semi-directifs. À travers l’analyse des discours et leur mise en perspective par confrontation avec la littérature scientifique, l’auteure a voulu questionner l’attrait que suscitent les entrepreneurs de startup en France – à l’instar de leurs homologues de la Silicon Valley. Les résultats montrent que les startupers sont animés par un fort désir de changement s’incarnant dans des réalisations concrètes et qu’ils assument des projections identitaires paradoxales. Ils constituent en cela un profil d’acteur social inédit, porteur d’innovations.
Synthesis of nanocomposite coating based on TiO2/ZnAl layer double hydroxides
Authors: Jovanov V. , Rudic O. , Ranogajec J. , Fidanchevska E.
Published: February 2017

The aim of this investigation was the synthesis of nanocomposite coatings based on Zn-Al layered double hydroxides (Zn-Al LDH) and TiO2. The Zn-Al LDH material, which acted as the catalyst support of the active TiO2 component (in the content of 3 and 10 wt. %), was synthesized by a low super saturation co-precipitation method. The interaction between the Zn-Al LDH and the active TiO2 component was accomplished by using vacuum evaporation prior to the mechanical activation and only by mechanical activation. The final suspension based on Zn-Al LDH and 10wt. % TiO2, impregnated only by mechanical activation, showed the optimal characteristics from the aspect of particle size distribution and XRD analysis. These properties had a positive effect on the functional properties of the coatings (photocatalytic activity and self-cleaning efficiency) after the water rinsing procedure.

Teachers and Mathematical Modeling
Authors: Quiroz Rivera Samantha Analuz , Rodríguez Gallegos Ruth
Published: February 2017

Mathematics cannot be reduced to the use of algorithms. The main objective of teaching mathematics in school is their application in real world situations. Mathematical modeling was born as an answer of this concerned and implies the relation between mathematics and applications. Because of that, teachers need to be correctly training in the use of mathematical modeling in their daily lesson plans. The aim of this study is to propose a methodology for help teachers purchase mathematical modeling as a strategy to teach mathematics. Our methodology is based on the analysis of teachers' conceptions about learning and teaching mathematics and after that promote their evolution. The main characteristic is the collaborative work between teachers and the researcher in cycles of discussion and classes' implementation. The evidence showed that teachers can actually change their conceptions about what is needed for teaching mathematics and design lesson plans using mathematical modeling.
Integration of Digital Technologies

Published: February 2017

This chapter presents an inquiry on how to integrate digital technologies (DT) in the teaching of mathematics in primary schools. The work focused on showing how collaborative practices between teachers during professional development can improve the process of integration and enable the configuration of a suitable land to cultivate a community of practice whose common interest is precisely integrate DT. The research design was based on the Design-Based Research (DBR) methodology, and the data analysis was performed using a systematic design process with focus on reflection on the practice, and under the iterative cycle of a workshop. The results suggest features that we consider necessary for the design of a professional development program whose purpose is to improve the integration of DT from school contexts themselves and based on the situated learning.

Published: February 2017

Advertisements can be divided into two main groups as analytical and narrative advertisements. Analytical content of an advertisement includes features of products and it addresses to consumers' rationality. On the other hand narrative advertisements focus on to create a story around a brand and addresses to consumers' emotions. This study focuses on the type of narrative advertisement, its development and practices in recent years. The study begins with a general frame of advertising history, a discussion of the distinctions between narrative and analytic modes of processing and transformation of narrative advertising. Narrative advertisements will be inspecting with the terms of narrative 1.0, 2.0 and 3.0. The term of narrative 3.0 is the main focus point of this study and it will be explained with the concepts of prosuming, user integration, viral, etc. At the end of the study, as a narrative 3.0 practice, Tru Blood: Revelation will be inspected.

Abstract. Interactions between seawater and benthic systems play an important role in global biogeochemical cycling. Benthic fluxes of some chemical elements (e.g., C, N, P, O, Si, Fe, Mn, S) alter the redox state and marine carbonate system (i.e., pH and carbonate saturation state), which in turn modulate the functioning of benthic and pelagic ecosystems. The redox state of the near-bottom layer in many regions can change with time, responding to the supply of organic matter, physical regime, and coastal discharge. We developed a model (BROM) to represent key biogeochemical processes in the water and sediments and to simulate changes occurring in the bottom boundary layer. BROM consists of a transport module (BROM-transport) and several biogeochemical modules that are fully compatible with the Framework for the Aquatic Biogeochemical Models, allowing independent coupling to hydrophysical models in 1-D, 2-D, or 3-D. We demonstrate that BROM is capable of simulating the seasonality in production and mineralization of organic matter as well as the mixing that leads to variations in redox conditions. BROM can be used for analyzing and interpreting data on sediment–water exchange, and for simulating the consequences of forcings such as climate change, external nutrient loading, ocean acidification, carbon storage leakage, and point-source metal pollution.

Published: February 2017

Se ha analizado el sistema médico tradicional en el territorio de los Pastos, Resguardo Indígena de Túquerres, Nariño, Colombia. Para los indígenas, la salud es producto de la relación armónica entre naturaleza, seres humanos y el mundo espiritual, al romperse uno de estos tres nexos, el cuerpo se enferma afectando tanto al individuo como a la familia.El enfoque fue hermenéutico en la comprensión de las prácticas de los comunitarios relacionadas con la medicina tradicional. La unidad de estudio fue la totalidad de médicos tradicionales (19), entre los cuales hay hierbateros, espirituales, yageceros y parteras. Los resultados han reflejado que la práctica de la medicina tradicional, que en el caso del Estado, algunos sectores de la Iglesia e Instituciones prestadoras de salud no aceptan esta práctica ancestral, persiguiendo al médico tradicional acusándolo de hechicero, embustero y mentiroso.Existen dos categorías de médicos tradicionales: los espirituales y los del cuerpo. Entre las más enfermedades más frecuentes del cuerpo está la gastritis, la úlcera, apendicitis, mal de vesícula, cáncer, fracturas y luxaciones. Entre las espirituales: el espanto, el mal viento, el miado del cueche, el maleficio y enfermedades que denominan “del alma”, como la envidia, la soledad, la tristeza, el egoísmo.El tratamiento va acompañado con un ritual. Para las espirituales se purifica a la persona y el entorno con sahumerio, se invoca a Dios y naturaleza, sol, agua, y los espíritus mayores. La percepción comunal: consideran que la medicina tradicional es una alternativa para la salud del cuerpo y el espíritu a través de plantas.

Resumo: Este estudo objetivou comparar os efeitos de duas doses de hiclato de doxiciclina sobre a contagem de hemácias, concentração de hemoglobina, hematócrito, contagem de leucócitos e plaquetas de cães com erliquiose. Foram estudados os grupos I, composto por cães saudáveis (n=6), negativos na sorologia para Ehrlichia canis e Leptospira spp., na PCR em tempo real para E. canis e Anaplasma platys e na semi–nested PCR para Babesia canis; grupos II (n=6) e III (n=6), compostos por cães com história clínica sugestiva, sorologia e/ou PCR em tempo real positivas para E. canis, e negativos na pesquisa de anticorpos anti-Leptospira spp., na PCR em tempo real para A. platys e na semi–nested PCR para B. canis. Os cães doentes foram tratados com hiclato de doxiciclina via oral a cada 12 horas por 30 dias (5 mg/kg, grupo II; 10 mg/kg, grupo III). Hemogramas foram feitos antes, decorridos 15 dias e aos 10 dias após o término dos tratamentos. Não houve diferenças entre os grupos nos tempos avaliados quanto às variáveis hemácias, hemoglobina, hematócrito e leucócitos. Observou-se diferença quanto aos trombócitos entre o grupo I e os grupos II e III (p<0,0001) no início do estudo. Aos 15 dias de tratamento, a média do grupo III foi menor que dos grupos I (p=0,008) e II (p=0,0007), indicando persistência da trombocitopenia, ausente no grupo II. Não houve diferença entre os grupos no tempo final, sugerindo que ambos os tratamentos promoveram aumento da contagem de plaquetas em cães naturalmente infectados por E. canis.

Durante esse período foram apreendidos 1.097 aves (47,2%), 720 répteis (31,0%), 498 mamíferos (21,4%) e cinco peixes (0,2%), totalizando 2.320 animais recepcionados, dentre eles, 0,6% estão presentes na lista de animais vulneráveis e ameaçados de extinção. A despeito das fiscalizações realizadas pelo IBAMA e policiamento ambiental, animais com risco de extinção continuam sendo retirados da natureza de forma predatória, sendo as aves as mais apreciadas que os demais grupos, considerando o número de animais recebidos pelo CETAS.

O estudo avaliou a influência de sistemas de cultivo e de métodos de preparo na atividade antioxidante e no teor de fenólicos de folhas e talos da couve manteiga (Brassica Oleracea L. var. acephala). Amostras de couve cultivadas pelo sistema convencional e orgânico foram pesadas, higienizadas e os talos separados das folhas. Foram submetidas aos modos de preparo: cru (couve in natura); calor seco (refogada) e calor úmido (imersa em água fervente). Avaliou-se à atividade antioxidante e os compostos fenólicos pelo método espectrofotométrico. A verificação de compostos fenólicos e compostos com atividade antioxidante foi realizada por Cromatografia em Camada Delgada (CCD). O sistema de cultivo orgânico e o preparo em calor seco foram os tratamentos que obtiveram os maiores percentuais de antioxidantes e teores de compostos fenólicos, principalmente, em folhas de couve.  A atividade antioxidante variou de 38 a 87% nas folhas e de 13 a 56% nos talos de couve. Quanto aos compostos fenólicos os teores médios estiveram entre 173 e 244 mg EAG/100g nas folhas e 86 e 180 mg EAG/100g nos talos. As análises por CCD revelaram que todos os extratos de folhas e talos de couve apresentaram compostos fenólicos bem como componentes com ação antioxidante, mas nem todos com correlação. Conclui-se que a combinação de sistema de cultivo orgânico e cocção em calor seco pode ser eficiente para preservação e ou aumento do teor de compostos fenólicos e da atividade antioxidante em talos e, principalmente, em folhas de couve.

Published: February 2017

Objetivo: Esse estudo teve por objetivo verificar o conhecimento dos alunos de enfermagem sobre o Teste do Pezinho, assim como sua forma de abordagem na graduação. Métodos: Trata-se de um estudo descritivo, transversal de abordagem quantitativa, com 168 acadêmicos de duas Instituições de Ensino Superior, do município de Uberaba/Minas Gerais. Para a coleta foi utilizado um questionário e os dados foram analisados pelo Programa Statistical Package for the Social Sciences. Resultados: Quanto ao conhecimento sobre o Teste do Pezinho, os principais resultados foram: confusão do Teste do Pezinho com impressão plantar (12%), comprometimento da etiologia das patologias diagnosticadas, equívoco quanto ao período e local para coleta do exame. Apenas cerca de 23% (N = 38) responderam corretamente todas as patologias triadas pelo Teste do Pezinho no Estado de Minas Gerais. O tema Teste do Pezinho foi abordado principalmente em aulas expositivas (67,4%) em disciplinas ofertadas nos semestres finais do curso de Graduação em Enfermagem, tais como: Assistência integral à saúde da criança e adolescente (41,5%), Enfermagem em pediatria (35,6%) e Enfermagem na saúde da criança (33,3%). Conclusão: Os estudantes de enfermagem possuem conhecimento adequado acerca do TP, mas há lacunas em alguns temas pertinentes a esse exame, tais como período e local de coleta, etiologia, quais as doenças detectadas, entre outros
O estruturalismo dialético, psicanálise e o nascimento da psicoterapia de grupo
Authors: Ilario Enidio , Terzis Antonios
Published: February 2017

O estudo busca mostrar a riqueza da abordagem grupal, que resgata
fontes esquecidas e constitutivas da teoria psicanalítica, amalgamadas no
constructo freudiano, formando um todo articulado que tende a velar suas
fontes primevas. Entre tais fontes, o idealismo alemão, o pragmatismo
americano e o estruturalismo, os últimos, nascentes à época de Freud,
contemporâneo de Peirce e Saussure. De tal matriz, sobretudo da noção
de alteridade como reconhecimento, a influência sobre uma geração de
psicanalistas, entre eles aqueles preocupados com a questão da grupalidade
e que produziram seus construtos no início do século XX, pertencentes à
Escola de Relações Objetais. Conjectura-se, neste estudo, que a inquietação
e a insatisfação desses autores com as limitações dos modelos existentes,
inclusive a metapsicologia, para explicação ou mesmo a compreensão dos
fenômenos da grupalidade, tenham contribuído para lançar as bases para o
projeto transdisciplinar da ciência da cognitiva.
A religiosidade/espiritualidade na prática do cuidado entre profissionais da saúde
Authors: Guilherme Lucas Tetzalff de Gerone
Published: February 2017

Contexto: A investigação científica sobre espiritualidade, religiosidade e saúde tem adquirido espaço nas rodas de debates e nas pesquisas acadêmicas, contudo, pouco se trata da espiritualidade, religiosidade em uma perspectiva teológica que contribua para o contexto cuidado em saúde. Objetivo: O presente estudo apresenta uma revisão de literatura sobre espiritualidade, religiosidade e saúde, especificamente, evidenciar as metodológicas destas literaturas no intento de apontar o papel da teologia na prática do cuidado entre profissionais da saúde. Métodos: Pesquisa de testes de mestrado, dissertações de doutorados e periódicos sobre espiritualidade, religiosidade e saúde nas bases de dados da CAPES e SCIELO. Resultados: encontram-se 348 dissertações de mestrado e teses de doutorado e 59 periódicos sobre espiritualidade, religiosidade e saúde. Entre 348 dissertações e teses, apenas 2,58% (9) são da área da teologia. Entre 410 (dissertações, teses e artigos) utilizou-se 29 para a discussão do tema, sendo apenas 2 estudos da teologia. Considerações: O tema é amplo, e por isso, faz-se necessário a continuidade de novas pesquisas interacadêmicas sobre a temática em questão. Nisto, considera-se a importância de mais estudos da teologia, visto sua significativa contribuição para a humanização na saúde e no cuidado integral.

Dry Eye in Patients With Diabetic Retinopathy
Authors: Khurana Geetika , Khurana Deeksha , Jain Rajesh
Published: February 2017

Purpose:

To study tear film changes in patients of Type 2 diabetes mellitus with and without diabetic retinopathy.

Method:

A hospital based, cross sectional, observational study including 40 patients of Type 2 diabetes mellitus with diabetic retinopathy and 40 patients without diabetic retinopathy. The parameters evaluated for each patient included a questionnaire (based on McMonnie’s Dry Eye questionnaire), Schirmer’s basic secretion test (BST) and Tear film break up time (TBUT).

Results:

The prevalence of dry eye in patients without diabetic retinopathy was 5% (Schirmer’s BST) and 42.5% (TBUT) as compared to 21.25% (Schirmer’s BST) and 82.5% (TBUT) in patients with diabetic retinopathy. Schirmer’s BST and TBUT were found decreased with the increase in severity of diabetic retinopathy (p<0.001).

Conclusions:

The prevalence and severity of dry eye, based on clinical parameters, was more in patients with diabetic retinopathy as compared to those without diabetic retinopathy.
Optic Disc Pit Maculopathy (ODP-M) Surgical Intervention and Outcome
Authors: Nasti Rashid Hammad , Vig Vipan , Singh Preetam , Singh Rajbir
Published: February 2017

Abstract We report the case of a 26 year old lady, presenting with complaints of gradual diminution of vision in her right eye (RE). Best corrected visual acuity (BCVA) was 20/60 and N12 in the RE and 20/20 and N6 in the left eye (LE). Fundus examination and optical coherence tomography (OCT) led to a diagnosis of optic disc pit maculopathy (ODP-M) in the RE. Pars plana vitrectomy, with an attempt to make an inner retinal fenestration adjacent to the temporal margin of the pit was done. An iatrogenic break was formed, which was used for subretinal fluid drainage and sealed by diode laser endophotocoagulation. Sulphur hexafluoride (SF6) was used for internal tamponade. At 6 months follow-up, BCVA in the RE had improved to 20/30 and N8. OCT revealed no subretinal fluid and decreased fluid in the schisis cavity. This case report therefore, demonstrates the efficacy of surgical intervention for ODP-M.

The development of multidrug resistance (MDR) in cancer cells to chemotherapy drugs continues to be a major clinical problem. MicroRNAs (miRNA, miR) play an important role in regulating tumour cell growth and survival; however, the role of miRs in the development of drug resistance in osteosarcoma cells is largely uncharacterized. We sought to identify and characterize human miRs that act as key regulators of MDR in osteosarcoma. We utilized a miR microarray to screen for differentially expressed miRs in osteosarcoma MDR cell lines. We determined the mechanisms of the deregulation of expression of miR‐15b in osteosarcoma MDR cell lines, and its association with clinically obtained tumour samples was examined in tissue microarray (TMA). The significance of miR‐15b in reversing drug resistance was evaluated in a mouse xenograft model of MDR osteosarcoma. We identified miR‐15b as being significantly (P < 0.01) downregulated in KHOSMR and U‐2OSMR cell lines as compared with their parental cell lines. We found that Wee1 is a target gene of miR‐15b and observed that transfection with miR‐15b inhibits Wee1 expression and partially reverses MDR in osteosarcoma cell lines. Systemic in vivo administration of miR‐15b mimics sensitizes resistant cells to doxorubicin and induces cell death in MDR models of osteosarcoma. Clinically, reduced miR‐15b expression was associated with poor patient survival. Osteosarcoma patients with low miR‐15b expression levels had significantly shorter survival times than patients with high expression levels of miR‐15b. These results collectively indicate that MDR in osteosarcoma is associated with downregulation of miR‐15b, and miR‐15b reconstitution can reverse chemotherapy resistance in osteosarcoma.
Delayed warming hiatus over the Tibetan Plateau
Authors: An Wenling , Hou Shugui , Hu Yongyun , Wu Shuangye
Published: February 2017

A reduction in the warming rate for the global surface temperature since the late 1990s has attracted much attention and caused a great deal of controversy. During the same time period, however, most previous studies have reported enhanced warming over the Tibetan Plateau (TP). In this study we further examined the temperature trend of the TP and surrounding areas based on the homogenized temperature records for the period 1980–2014, we found that for the TP regions lower than 4000 m the warming rate has started to slow down since the late 1990s, a similar pattern consistent with the whole China and the global temperature trend. However, for the TP regions higher than 4000 m, this reduction in warming rate did not occur until the mid‐2000s. This delayed warming hiatus could be related to changes in regional radiative, energy, and land surface processes in recent years.
