Published: February 2019

Genetic variability in progenies of Eucalyptus grandis and Eucalyptus urophylla for tolerance to hydric deficit. Information on the adaptation and genetic potential of Eucalyptus under water deficit conditions is necessary owing to the increasing cultivation of the genus in regions considered as "forest frontiers". Therefore, the present study aimed to estimate genetic variability, genotypic and phenotypic correlations, and estimated genetic gains in progenies of E. grandis and E. urophylla. Two progeny tests (TP1 and TP2) were performed in the municipality of Vila Nova dos Martirios (state of Maranhão, Brazil), in 30-month-old plants. The experiment was carried out using a randomized block design, with five replicates, nine plants/square plot, and 144 treatments in TP1 and 264 in TP2. Statistical analysis was performed and genetic parameters were estimated. Individual and within-progeny heritabilities were corrected using the kinship coefficient for eachspecies. Genetic gains were low, ranging from 0.96 to 6.39% for E. grandis and 1.62 to 5.48% for E. urophylla. The diameter at breast height (DBH) showed a higher coefficient of genetic variation compared with the other measured characteristics, suggesting a higher potential for selection. High, positive, and significant correlations were observed between DBH and height (H), indicating the possibility of obtaining gains based on a single characteristic. Heritability was considered low, thus directly influencing the selection gains, which were lower than those commonly reported in other studies. These findings provide important information for breeding programs in areas of forest expansion.

Authors: Teixeira João Paulo Allain , Castilho Natalia Martinuzzi 
Published: February 2019

O artigo aborda os recentes fenômenos de mudanças presidenciais ocorridos em países da América Latina de forma a investigar as nuances do conceito de “novo golpismo”. Discutimos em que medida os eventos até aqui intitulados de golpes institucionais podem indicar os desafios a serem enfrentados pelo constitucionalismo naquelas sociedades, marcadas pelo modo colonial de reprodução das relações de poder. O estudo compara o atual estado da arte do constitucionalismo latino americano com os recentes acontecimentos institucionais que invocam uma possível fragilidade nas estruturas desses Estados Democráticos de Direito. Realizamos, para tanto, uma pesquisa bibliográfica e documental, centrada nas interfaces do tema com a Ciência Política. A análise explora, a partir dessa aparente contradição, as relações entre colonialismo, colonialidade e direito, no intuito de buscar possíveis respostas aos desafios do fortalecimento da democracia em sociedades periféricas.

Published: February 2019

Context.—
Infectious gastroenteritis is caused by various pathogens, including bacteria, viruses, and parasites.

Objective.—
To compare the performance of Seegene Allplex Gastrointestinal (24 targets: 13 bacteria, 5 viruses, and 6 parasites in 4 panels), Luminex xTAG Gastrointestinal Pathogen Panel (15 targets: 9 bacteria, 3 viruses, and 3 parasites), and BD MAX Enteric panel (5 bacteria and 3 parasites). We estimated the agreement among 3 molecular assays.

Design.—
A total of 858 stool samples (554 bacterial/parasite and 304 viral pathogens) were included. A consensus positive/negative was defined as concordant results from at least 2 tests. To evaluate the agreement among the assays, κ value was calculated.

Results.—
The overall positive percentage agreements of Seegene, Luminex, and BD MAX were 94% (258 of 275), 92% (254 of 275), and 78% (46 of 59), respectfully. For Salmonella, Luminex showed low negative percentage agreement because of frequent false positives (n = 31) showing low median fluorescent intensity. For viruses, positive/negative percentage agreements of Seegene and Luminex were 99%/96% and 93%/99%, respectively. Compared with routine microbiology testing, Seegene, Luminex, and BD MAX additionally identified 39, 40, and 12 pathogens, respectively. Sixty-one cases (16 cases with Seegene, 51 cases with Luminex, and 1 case with BD MAX) showed positive results for multiple pathogens, but only 3 were consensus positive.

Conclusions.—
These multiplex molecular assays appear to be promising tools for the detection and identification of multiple gastrointestinal pathogens simultaneously. However, careful interpretation of positive results for multiple pathogens is required.
Les Cordes-de-Bois d’Antonine Maillet, ou La vraie vitalité acadienne
Authors: Hogue Myra 
Published: February 2019

Cet article propose une lecture des Cordes-de-Bois d’Antonine Maillet qui, encadrée par La part du diable, essai consacré au Saint-Élias de Jacques Ferron et à son remaniement du discours de la Révolution tranquille, y sondera la présence d’un renversement du portrait hégémonique qu’est l’Évangéline de Longfellow et la doctrine religieuse lui correspondant. Les Cordes-de-Bois offre, effectivement, une représentation de la population acadienne et du clergé qui, loin de respecter l’Église et son application intransigeante d’une doctrine pénitente, déjoue toutes les règles dans une ode à l’imparfaite vie terrestre. Dans cet univers digne de la « vraie vitalité acadienne », une lecture miséricordieuse de l’Évangile se substitue au dogmatisme religieux et un clan de pécheurs, à de fervents croyants.
La pratique anthologique en Acadie
Authors: Doyon-Gosselin Benoit 
Published: February 2019

Cet article vise à mieux comprendre le rôle des anthologies littéraires en Acadie. L’anthologie littéraire, en Acadie comme ailleurs, suppose des mécanismes d’inclusion et d’exclusion reposant sur des critères qui se veulent objectifs, mais qui, dans les faits, le sont rarement. Encore aujourd’hui, l’anthologie littéraire acadienne demeure au stade de l’inventaire producteur, et cette tendance à vouloir produire une littérature par l’existence même de l’anthologie se reflète de trois façons souvent concomitantes, toujours complémentaires : 1) retenir des textes dont la valeur littéraire est moindre, mais qui permettent de se donner un corpus ; 2) inclure des auteurs qui n’ont jamais publié un livre ; et 3) se concentrer sur les textes contemporains.

Mujeres y emblemas: una visión simbólica de la condición femenina en la Edad Moderna
Authors: García Arranz José Julio 
Published: February 2019

ABSTRACT: The difficult situation of women in the Modern Period, marked by the strong patriarchal and androcentric character of the official culture and ideology of the moment, and their high degree of social marginalization, has been frequently analysed through various literary sources such as theatre, fiction or travel literature, collections of proverbs and sermons, and, above all, moral and doctrinal texts. However, for some time now, a new approach to the issue has been attempted which has proven to be of singular importance when observing the effect of the aforementioned directives of the dominant ideology on the familial and social role of women: illustrated symbolic literature. Through its various forms of expression--emblems, badges, hieroglyphics, allegories--this genre became, especially from the final decades of the 16thcentury, a perfectly calibrated and effective instrument when channelling the political, moral and doctrinal orientation of citizens. In the present study I offer an overview of how emblematic treatises and repertoires of allegories offer us excellent examples of the construction of the symbolic image that the dominant elites of modern times seek to spread and impose on the female gender, and their well-established and channelled behavioural norms.

KEYWORDS: Modern Period; Emblems; Female Marginality; Androcentric Control.

RESUMEN: La difícil situación de la mujer en la Edad Moderna, marcada por el fuerte carácter patriarcal y androcéntrico de la cultura e ideología oficiales del momento, y su alto grado de marginación social han sido analizados con frecuencia a través de diversas fuentes literarias como el teatro, la literatura de ficción o de viajes, las colecciones de refranes y sermones, y, sobre todo, los textos morales y doctrinales. Sin embargo, desde hace algún tiempo se está ensayando una nueva vía de aproximación al problema, y que resulta de singular importancia a la hora de constatar las mencionadas directrices de la ideología dominante sobre el papel familiar y social de la mujer: la literatura simbólica ilustrada. Por medio de sus diversas formas de expresión --emblemas, empresas o divisas, jeroglíficos, alegorías...--, este género se convirtió, sobre todo a partir de los decenios finales del s. XVI, en un instrumento perfectamente calibrado y eficaz a la hora de encauzar la orientación política, moral y doctrinal de los ciudadanos. En el presente trabajo ofrecemos una panorámica de cómo los tratados emblemáticos y los repertorios de alegorías nos ofrecen inmejorables ejemplos de la construcción de la imagen simbólica que las élites dominantes de los tiempos modernos pretenden difundir e imponer del género femenino, y de sus bien establecidas y canalizadas normas de comportamiento.

PALABRAS CLAVES: Edad Moderna; Emblemática; marginalidad femenina; control androcétrico.
Mulieris typus: lo femenino en la Emblemática y la Cultura visual
Authors: Escalera Pérez Reyes , García Arranz José Julio 
Published: February 2019

Hacia los años ochenta del pasado siglo comenzó a adquirir notoriedad en España una corriente historiográfica de creciente desarrollo en las décadas posteriores, que se servía esencialmente del estudio de una serie de fuentes documentales y literarias con el fin de profundizar en el alto grado de marginación social que padeció la mujer de los tiempos modernos en nuestro país o en Europa. Sin embargo, no será hasta la entrada en el nuevo milenio que encontremos los primeros testimonios específicos de una nueva vía de aproximación a esta realidad: el análisis de la condición femenina a través los ingenios retóricos verbo-visuales de aquellas centurias.
En los textos reunidos en la sección Dosier encontraremos abundantes ejemplos de cómo el género gráfico-textual o verbo-visual de los libros de emblemas y empresas fue un fiel reflejo de los diversos modelos femeninos establecidos en los tiempos modernos, y de la definición de la figura de la mujer en sus diversos roles sociales, ya sea el de doncella, casada, viuda, monja o meretriz. Recurriendo al atractivo que ejercen sus imágenes, y al alto poder ejemplificador y moralizante de sus comentarios y declaraciones, con el habitual recurso a episodios míticos y bíblicos, personajes históricos o exemplaprocedentes del mundo animal y vegetal, temas con los que las élites culturales del momento –y a través de ellas el público– se encontraban familiarizadas gracias al teatro o la poesía, se precisan de manera sistemática las virtudes que debe cultivar la mujer honesta –incluyendo la sumisión al hombre y su silenciosa reclusión hogareña–, y los comportamientos que debe desterrar como inconvenientes o pecaminosos.
Choosing reference genes for RT-qPCR for Fusarium graminearum plant infection (In Planta) and In Vitro growth studies based on transcriptomic data
Authors: Lin Xiaorong , Li Hongchen , Wang Zonghua , Olsson Stefan 
Published: February 2019

Background. Choosing reference genes for RT-qPCR for the study of transcriptomic responses of target genes is often done using “standard” reference genes (housekeeping genes) selected before the genomic era. Now, published transcriptome data can be used to aid in this selection to avoid the selection of a reference gene that varies and obscure results.
Methods. We use transcriptome data for the model pathogen fungus Fusarium graminearum to select housekeeping genes for In Vitro and In Planta conditions. Transcriptome data was downloaded from a publicly available database. We selected a database where transcriptome chip data from many experiments using the same chip has been deposited divided the downloaded data into In Vitro and In Planta conditions based on the information about the experiments.
Results. We ranked the genes with the least variation (relative difference between maximum and minimum expression) across each dataset. Genes previously shown to perform well as reference genes for In Vitro conditions in a similar analysis as ours also performed well for In Vitro conditions in our dataset but worked less well for In Planta conditions. We found 5 reference genes that performed well under both In Planta conditions and In Vitro conditions.
Discussion. Even if these 5 reference genes performed well, for other (new) target conditions we recommend making a transcriptome analysis to select well performing reference genes for RT-qPCR if possible. Alternatively, select 2 of the 5 genes that we show here performed well under both In Planta and In Vitro conditions.
Molecular and Materials Engineering for Delivery of Peptide Drugs to Treat Type 2 Diabetes
Authors: Varanko Anastasia K. , Chilkoti Ashutosh 
Published: February 2019

AbstractType 2 diabetes is exploding globally. Despite numerous treatment options, nearly half of type 2 diabetics are unsuccessful at properly managing the disease, primarily due to a lack of patient compliance, driven by adverse side effects as well as complicated and frequent dosing schedules. Improving the delivery of type 2 diabetes drugs has the potential to increase patient compliance and thus, greatly enhance health outcomes and quality of life. This review focuses on molecular and materials engineering strategies that have been implemented to improve the delivery of peptide drugs to treat type 2 diabetes. Peptide drugs benefit from high potency and specificity but suffer from instability and short half‐lives that limit their utility as therapeutics and pose a significant delivery challenge. Several approaches have been developed to improve the availability and efficacy of antidiabetic peptides and proteins in vivo. These methods are reviewed herein and include devices, which sustain the release of peptides in long term, and molecular engineering strategies, which prolong circulation time and slow the release of therapeutic peptides. By optimizing the delivery of these peptides and proteins using these approaches, long‐term glucose control can be achieved in type 2 diabetes patients.

Published: February 2019

AbstractPolymeric dielectrics play a key role in the realization of flexible organic electronics, especially for the fabrication of scalable device arrays and integrated circuits. Among a wide variety of polymeric dielectric materials, aromatic polyimides (PIs) are flexible, lightweight, and strongly resistant to high‐temperature processing and corrosive etchants and, therefore, have become promising candidates as gate dielectrics with good feasibility in manufacturing organic electronic devices. More significantly, the characteristics of PIs can be conveniently modulated by the design of their chemical structures. Herein, from the perspective of structure optimization and interface engineering, a brief overview of recent progress in PI‐based dielectrics for organic electronic devices and circuits is provided. Also, an outlook of future research directions and challenges for polyimide dielectric materials is presented.

AbstractBatteries constructed via 3D printing techniques have inherent advantages including opportunities for miniaturization, autonomous shaping, and controllable structural prototyping. However, 3D‐printed lithium metal batteries (LMBs) have not yet been reported due to the difficulties of printing lithium (Li) metal. Here, for the first time, high‐performance LMBs are fabricated through a 3D printing technique using cellulose nanofiber (CNF), which is one of the most earth‐abundant biopolymers. The unique shear thinning properties of CNF gel enables the printing of a LiFePO4 electrode and stable scaffold for Li. The printability of the CNF gel is also investigated theoretically. Moreover, the porous structure of the CNF scaffold also helps to improve ion accessibility and decreases the local current density of Li anode. Thus, dendrite formation due to uneven Li plating/stripping is suppressed. A multiscale computational approach integrating first‐principle density function theory and a phase‐field model is performed and reveals that the porous structures have more uniform Li deposition. Consequently, a full cell built with a 3D‐printed Li anode and a LiFePO4 cathode exhibits a high capacity of 80 mA h g−1 at a charge/discharge rate of 10 C with capacity retention of 85% even after 3000 cycles.
Nickel–Cobalt Diselenide Nanosheets Supported on Copper Nanowire Arrays for Synergistic Electrocatalytic Oxygen Evolution

Published: February 2019

AbstractRational nanoarchitecture design and smart hybridization of bespoke catalysts can greatly accelerate the sluggish kinetics of oxygen evolution reaction (OER) in electrochemical water splitting. Here, hierarchical NixCo1−xSe2 porous nanosheets are synthesized on Cu nanowire arrays (CNW) to fabricate highly efficient core/shell structure integrated OER electrode. Highly conductive CNW arrays are first obtained via the reduction of the pre‐prepared CuO nanowire arrays. NixCo1−x precursor nanosheets are then grown on CNW via hydrothermal route, and the following selenylation led to in situ formation of NixCo1−xSe2 porous nanosheet. In the integrated electrode, the highly conductive CNW core can realize efficient electron transport. The hierarchical core/shell nanoarray structure can provide abundant catalytic active sites and more void space to release gas bubbles, and meanwhile prevent the underneath Cu nanowire core from oxidation. The synergistic effects of optimized components and smart structure of the integrated electrode afford a remarkable OER activity with a low potential of 1.423 V versus reversible hydrogen electrode (RHE) at 10 mA cm−2 current density, a small Tafel of 58 mV dec−1, and excellent stability in alkaline electrolyte. The present fabrication approach offers a direction in the design and synthesis of integrated catalysts on conductive substrates for promising electrocatalytic applications.

AbstractSkin‐interfaced electrochemical sensing devices are widely developed for biochemical sensing at molecular levels. However, the sensing electrodes fabricated with photolithography or printing technique are hard to achieve high stretchability without special designs like serpentine shape. Also, most of them require wired connections with external electrochemical workstations for data acquisition or on‐board batteries to power the circuits, which largely restrain the flexibility, simplification, and miniaturization of the devices. Here, a battery‐free, wireless, and epidermal electrochemical system is presented for in situ biochemical sensing. The sensing component of the system is a stretchable electrode array all‐printed with soft polymer and conductive silver nanowires. The electrodes show stable electrical properties within strain range of 0–50%, without serpentine designs. The electronic component of the system is a fully integrated flexible circuit board with near field communication module, which enables wireless energy harvesting and data transmission with smartphones. The system demonstrates good performance in real‐time on‐body sweat analysis for simultaneous quantitative detections of glucose, hydrogen, sodium, and potassium. This battery‐free and wireless epidermal electrochemical system provides a simplified, miniaturized, and flexible solution for a wide range of biochemical platforms, including wearable and implanted bioelectronics.
