RESEARCH ON PM2.5 CONCENTRATION COMBINATION FORECASTING MODEL BASED ON COR-SVM
Authors: Feng X. Y. , Tian P. , Shi Y. J. , Zhang M.
Published: October 2019

Abstract. PM2.5 is a pollutant that can enter the lungs, threatening human health and affecting people’s living and traveling. In this paper, we use multivariate linear regression, support vector machine and their combined prediction method to predict the concentration of PM2.5. It is significant for the convenience of healthy life. This paper is based on a series of meteorological data such as O3 concentration, CO concentration, SO2 concentration, PM2.5 concentration and PM10 concentration from 2014 to 2018 in Beijing. By calculating the correlation coefficient between the concentration of PM2.5 and the concentration of the other four components, the multivariate linear regression equation was fitted by using the correlation coefficient with high correlation as the factor of multiple linear regression. Then we use support vector machine regression prediction method to predict the concentration of PM2.5. The combined prediction method is obtained by weighing the two prediction results. It is found that the prediction method of support vector machine is better in dealing with large-scale and small sample data prediction, and the multi-linear fitting method is better in processing short-term prediction. The combined prediction results based on correlation coefficients combine the advantages of the two prediction methods, and the prediction results are more reasonable.
« La mémoire au féminin : Lecture de C’est le soleil qui m’a brûlée de Calixthe BEYALA et de Déchoucaj’ œuvre photographique de Myriam MIHINDOU »
Authors: ALLOGHO MANTWANI Canissius
Published: October 2019

Ce travail : «la mémoire au féminin : Lecture de C’est le soleil qui m’a brûlée de Calixthe Beyala et de Déchoucaj’ œuvre photographique de Myriam Mihindou » interroge la question de la représentation de la femme par la femme dans le monde ancestral et phallocratique. À travers les notions de corps, d’écriture et d’évocation mémorielle, politique et historique, cet article décline les enjeux d’une implication féministe dans l’acte de représentation de la mémoire de la femme. Ainsi, cette étude montre comment nos deux auteurs, à travers un univers photographique et un espace littéraire au féminin, travaillent à une certaine réhabilitation ontologique et sociale de l’être féminin notamment, par une déconstruction des dominations et des violences de la société sur les femmes.
“The Breath of Flowers That Perished”: Imperial Ecologies in Mark Twain's Early Letters
Authors: Heryford Ryan
Published: October 2019

This article will trace Mark Twain's early notes and letters to the Sacramento Union and Alta California during his four-month stay on the Hawaiian Island in 1866 and his subsequent trip down the Rio San Juan in Nicaragua later that year, considering his poetic meditations on a diversity of flora and fauna alongside his occasionally direct and sometimes elusive commentaries on territorial annexation, missionization, and settler occupation in the Pacific and beyond. Reading across a colonial archive of nineteenth-century environmental surveys of the Pacific atolls and the Central American isthmus, this article will highlight Twain's alignment toward and departure from a tradition of writing about non-European ecologies as bound within the exotic picturesque. Twain's ambivalent, non-Western ecologies mark a politics that extends well beyond his familiar satires and pointed expositions, offering pathways for reimagining the place of nonhuman environments throughout his subsequent literary canon.
Mark Twain and the Conflicted Metaphor of Nature
Authors: Bird John
Published: October 2019

In 1978, William Rueckert coined the term “ecocriticism,” defining it as “the application of ecology and ecological concepts to the study of literature.” He proposed three postulates about literature, which are all metaphors. Taking a cue from Rueckert, this article examines the metaphorical nature of Mark Twain's nature writing, looking at the way his works function as stored energy, as energy pathways, and as both fossil fuel and renewable resources, using passages from The Adventures of Tom Sawyer, “Old Times on the Mississippi,” and Adventures of Huckleberry Finn. Unlike Rueckert's rather sunny postulates, this article sees a darker side in Twain's works, a recognition that is revealed in his conflicted metaphors of nature. Just as Samuel Clemens and Mark Twain have long been considered divided, we as humans are divided: we are both a part of and apart from nature, a bifurcation and conflict that is contained in Twain's metaphorical language.
Nature as Travel Guide: Mark Twain and Hawaii in Writing the American Frontier
Authors: Vandenbossche Lisa
Published: October 2019

This article traces the evolution of Mark Twain's early travel writing by comparing intersections between recorded travel and nature writing in Twain's 1866 letters for the Sacramento Union and his 1872 full-length book about the America West, Roughing It. In his twenty-five published letters, Twain critiques past travel guides and histories that distract visitors—and by extension readers—from what is in front of them, forcing their attention away from the reality of the people and places they encounter. In Twain's first full-length travel account, 1869's The Innocents Abroad, this critique is more fully realized, as Twain articulates an even stronger lament against tour guides and books that script a travelers' experiences with new spaces. When Twain returns to writing about the American frontier in Roughing It, he condenses the narration of his Pacific travel for his second full-length account, employing nature as a narrative structure that enables him to direct a reader's attention to travel experiences as they unfold. Here nature serves as a witness that preserves stories and a phenomenon that punctuates Twain's experiences uncovering these stories, thus working to frame human action in the text, drawing the attention of both travelers and readers to what is immediately in front of them. This article argues that, in employing this model, Roughing It insists on the importance of natural descriptions in travel writing, and that Twain's work ultimately illustrates the essential role that nature plays in shaping the human experience of travel on the unscripted frontiers of the Pacific and American West, for travelers and readers alike.

Published: October 2019

The objective of this study was to evaluate different pre-germination treatments, histochemical characteristics and physiological performance of Sapindus saponaria L. seeds as a function of temperature and the germination substrate. The S. saponaria seeds were collected in the municipality of Rio Verde, GO, and analysed through the execution of 2 tests (dormancy breakage and germination tests). Test 1 consisted of 10 treatments for overcoming dormancy, whereas test 2 consisted of a 35-day evaluation of germination on several substrates (paper and sand) under the following 4 temperature conditions: 20, 25, 30°C and alternating 20-30°C (± 0.5°C). The results of the dormancy breakage and germination tests were submitted to analysis of variance (ANOVA), and the means were compared by the Tukey test. Scarifying S. saponaria seeds with concentrated sulfuric acid for 90 min provided a relatively high speed and percentage of emergence, without causing anatomical damage. Pre-germination treatments using high- (42 °C) or low-(10 °C) temperature stress caused cellular damage in the endosperm region of S. saponaria seeds. The greatest percentage of S. saponaria seeds germinated on a paper substrate at 30°C.

The growing need to increase food production constitutes a serious scientific-technological challenge, requiring the expansion of cultivated sites also with the utilization of degraded areas, such as soils affected by salts. In order to achieve that, alternatives to mitigate such limitations have been pursued, such as the use of biofertilizers in the formation process of neem seedlings. In the pursuit for alternative and ecological control methods considered healthy and sustainable, the use of the neem tree (Azadirachta indica) associated with organic inputs in semiarid regions is highlighted, since this species possesses azadirachtin as the main bioactive compound, capable of acting against more than 418 plague species due to its insecticidal properties. An experiment was conducted in a screened plant nursery in the municipality of Areia – PB, in the period from January to July 2016, to evaluate the effects of the supplemental irrigation with saline waters on the absolute growth of neem seedlings in soil with biofertilizer. The substrate was a Dystrophic Red- Yellow Latosol. The experimental design was in randomized blocks, in a 5x2x3 factorial scheme, with four replications. The treatments were irrigated with five levels of water salinity (0.5; 1.5; 3.0; 4.5; 6.0 dS m-1), in the soil without and with common fermented bovine biofertilizer, and evaluated after three periods: 30, 60, and 90 days after the emergence of the plantlets, for the determination of the absolute growth in AP, DC, IAF, MSR, MSPA, and MST. The liquid fermented biofertilizer, after diluted, was applied a single time in a 1:3 proportion, two days before sowing, at the level of 10% the volume of the substrate. The treatments with fermented bovine biofertilizer provided better conditions for the growth and development of the neem through osmotic effect than in the soil without the input as a function of the time.

Published: October 2019

The climatic influence in minerals content of peach palm heart (Bactris gasipaes Kunth) was studied and a quick method was assessed to determine Mg, Cl, K and S in the basal portion of peach palm heart based on multivariate predictive model using agro-meteorological data. A total of 24 samples of B. gasipaes Kunth were collected along 14 to 18 months of cultivation, growing in two types of terrain: hillside and lowland. Principal component analysis (PCA) was used to select principal components. The data were modeled using partial least squares regression (PLS). Low average relative prediction errors (4.60%) confirm the good predictability of the models. The factors that most influence the minerals content prediction model were the rain precipitation and solar radiation. The results show that predictive model can be used as rapid method to determine the mineral content in the basal portion of peach palm heart factories and may help to choose geographical regions suitable for the establishment of new peach palm plantations. The models can provide reductions of cost and time analysis to palm heart without generating laboratory effluents. This is the first time in which multivariate analysis is used to generate models to predict minerals concentration in the basal portion of peach palm hearts, quantifying numerically the intensity of climatic factors in the minerals content.

Considering the hypothesis that laminitic horses display changes in the kinematics of their forelimbs and clog type orthopedic devices can be beneficial in such cases, the objectives of this study were to compare the stride pattern of healthy horses versus that of horses with chronic laminitis and to assess the kinematic effects of three types of clog shoes on the stride of laminitic horses. Six healthy and six laminitic mares were subjected to a kinematic evaluation at a walk. The horses with laminitis were evaluated before and after the use of three different models of clog type orthopedic shoes on the hooves of both their forelimbs. The treatment types that were administered were the application of no shoes, wooden shoes, leather and ethylene-vinyl acetate (EVA) shoes, and wooden and EVA shoes. The horses with laminitis have a stride length that is reduced by 11% (P = 0.03), and in the swing phase, by 18% (P = 0.004), and the relative stance phase of each limb is prolonged by 6% (P = 0.02) when compared with the healthy group. However, values associated with the stride duration, stance phase duration, breakover duration, speed, and frequency were not significantly different among the laminitic groups. Further, no statistical differences were found in the comparison of the outcomes among the treatments administered to the horses with laminitis, except in their stride length, which was longer in the horses shod with wooden clogs when compared with in the unshod laminitic horses (P = 0.04). It was concluded that horses with stable chronic laminitis display changes in the kinematics of their forelimbs while walking. Immediate and remarkable beneficial effects were not observed with the use of all the types of orthoses; however, the wooden clog resulted in a significant improvement in the length of the stride. Further studies are needed to verify the prolonged effects of clog shoe-type ortheses in the different phases of equine laminitis.

Leptospirosis is a zoonosis of worldwide distribution in which the agent can infect several animal species and accidentally humans. In view of the limited number of studies on anti-Leptospira antibodies in wild animal species, especially those living in aquatic environments, we sought in this study to investigate the presence of these antibodies in the spot-legged turtle (Rhinoclemmys punctularia) maintained in captivity in the Rodrigues Alves Botanical Garden–Amazon Zoobotanical Park, located in Belém, Pará State, Brazil. Serum samples were collected from 31 turtles, and identification of anti-Leptospira antibodies was performed using the microscopic agglutination test, using a collection of 31 live antigens which represent 19 serogroups of Leptospira. Among the analyzed samples, 54.83% (17/31) were observed to be reactive, and co-agglutination was detected in a further six samples which were not accounted for in the frequency of serogroups. The most frequently detected serogroups were Tarassovi 72.72% (8/11), Celledoni 18.18% (2/11), and Pomona 9.09% (1/11)], with titers ranging from 200 to 400, being this the first study to report infection of these serogroups in this species of chelonios. The animals were kept in water tanks, which probably favored the transport of the agent and allowed its transmission to the spot-legged turtle. We thus confirmed presence of anti-Leptospira antibodies in chelonians maintained in the Rodrigues Alves Botanical Garden.

Published: October 2019

This case study describes the cytological and histopathological findings of cutaneous masses in a bovine, including a peripheral nerve sheath tumor (PNST), vaccine-associated granulomatous inflammation, and eosinophilic inflammation due to parasitosis. A six-year-old undefined cow (SRD) presented with heterogeneous cutaneous lesions including multiple nodules in the left paralumbar fossa, bilaterally at the withers, and scattered along the dorsum, limbs and near the tail; some lesions were associated with ticks. Cytology of these nodules showed benign mesenchymal neoplasia (paralumbar fossa), granulomatous and pyogranulomatous inflammation (withers) and keratin (dorsum). Histopathology, in this order, confirmed PNST, post-vaccination granuloma, and eosinophilic dermatitis. A peripheral nerve sheath tumor was suspected based on the histological findings, showing a well-delineated proliferation of fusiform cells arranged in plexiform structures, which appeared red by Masson's Trichrome stain. The diagnosis was confirmed by immunohistochemistry (anti-S100 antibody). Vaccine reaction often occurs in cattle, and cytological examination is sufficient to determine the inflammatory process. Eosinophilic dermatitis is usually accompanied by perivascular inflammation and reflects the exfoliative process by the oral apparatus of the parasite.

Crossing a border: Dutch foundlings migrating from or to another country

Within the group of Dutch foundlings, 28% are migratory foundlings: children coming from abroad to the Netherlands (inbound foundlings), and children going abroad from the Netherlands (outbound foundlings). According to the rational choice theory, there is at some point a rational decision behind human action, based on consideration of costs and benefits – terminology reminiscent of the origins within economic science. When viewed from that perspective, cross-border abandonment may be regarded to be a conscious effort to hinder detection. After all, abandonment of foundlings has been a criminal offence in the Netherlands since at least the Middle Ages. There is therefore also a vested interest in not attracting attention. Anyone abandoning a child and wishing to protect their identity will be attracted to locations that lack effective supervision, defined as guardianship within the criminological routine activities theory. However, the less familiar a location, the trickier it is to avoid visibility. Does the rational consideration of costs and benefits result in migratory foundlings being abandoned just over the border (in order that the perpetrators attract the least possible attention) or actually further inland (in order to detract from the cross-border activity, for example)? Is there a comparable choice in terms of distance when people abandon native foundlings – children found in their country of birth? Relevant questions indeed, as greater insight into such variables can support the direction taken by detection activities. This study is an exploratory analysis of the distance between the domicile or birth location and the abandonment location of cross-border foundlings. The results will then be compared with the distances in the case of domestic foundlings.
DIZER DEUS E O HUMANO NO CONTEXTO DA PÓS-MODERNIDADE
Authors: CALDEIRA CLEUSA
Published: October 2019

O contexto pós-moderno está marcado pela forte crise de sentido que experimenta os indivíduos, depois do colapso do sujeito moderno e a emergência da vulnerabilidade. Existem inúmeras interpretações desta vulnerabilidade, da mesma forma que multiplicam os contextos e seus sujeitos. Esta nova subjetividade, marcada pela aguda consciência da finitude, da culpabilidade e da possibilidade de redenção que chega pela alteridade amorosa, torna-se o novo o solo fecundo para pensar e dizer a experiência de Deus e do humano no coração da pós-modernidade. Nesse horizonte, este texto se propõe a apresentar duas versões de narrativas da experiência cristã em tempos de fragmentos, que nos coloca em contato com a pluralidade de aproximação ao mistério humano-divino em tempos pós-modernos.
LAS IGLESIAS EVANGÉLICAS EN PANAMÁ
Authors: Nevache Claire
Published: October 2019

En 2016, surgieron en Panamá, señales de una mayor injerencia de las Iglesias Evangélicas en la política, especialmente en razón de su movilización en oposición al proyecto de ley 61 que promovía la educación sexual en centros educativos. Dicha movilización logró frenar el proyecto, y en los meses posteriores, diversos proyectos de políticas públicas orientados a la igualdad de género fueron igualmente frenados. En este contexto, esta investigación busca determinar si estamos frente a un nuevo actor político, y en caso tal, estudiar sus características. Para ello, hacemos un breve recuento histórico de la presencia de los evangélicos en Panamá y de sus tentativas anteriores de entrada a la política. A continuación, estudiamos la incorporación actual de los evangélicos a la política panameña. Finalmente, buscamos caracterizar este nuevo actor y determinar el significado del surgimiento del mismo para la democracia panameña.
Alterar limites e categorias de áreas protegidas é necessariamente ruim? Um estudo de caso em duas unidades de conservação estaduais da Amazônia brasileira
Authors: Borges Sérgio , Souza Francisco , Moreira Marcelo , Camargo Yara
Published: October 2019

A revisão de limites e categorias de unidades de conservação têm se tornado comum na Amazônia brasileira. Entretanto, poucos estudos caracterizaram os eventos históricos e os papéis desempenhados por distintos atores regionais nos processos técnicos e políticos associados a estes eventos. Neste estudo foram investigados os eventos históricos subjacentes à reconfiguração de limites e categorias de dois Parques Estaduais no Estado do Amazonas. Foram registrados 56 eventos históricos e identificados 26 atores institucionais relevantes na gestão das duas unidades de conservação. A revisão dos limites e categoria se concretizou no Parque Estadual Rio Negro – Setor Sul. Por outro lado, as demandas sociais pouco estruturadas e um contexto desfavorável na política ambiental do Amazonas impediram a conclusão do processo no Parque Estadual do Rio Negro – Setor Norte. A revisão de limites e categorias pode ser uma estratégia válida de resolução parcial dos conflitos fundiários em unidades de conservação. Propostas desta natureza, no entanto, não devem ser banalizadas, mas baseadas em detalhadas análises técnico-científicas negociadas entre as comunidades locais, gestores e representantes políticos a fim de se evitar prejuízos na proteção da biodiversidade.
As iniciativas de desenvolvimento em comunidades agroextrativistas na Amazônia
Authors: Felizardo Alciene Oliveira , Rocha Carla Giovana Souza
Published: October 2019

Este trabalho analisa o enfoque orientador de iniciativas de desenvolvimento e sua relação com o estilo de agricultura dos agroextrativistas na Amazônia, em particular nas ilhas de Abaetetuba, estado do Pará. Foram adotados recursos metodológicos de pesquisa qualitativa por meio da realização de entrevistas semiestruturadas e análise documental. Verificou-se que as iniciativas foram orientadas por uma matriz agroindustrial caracterizada por ações pré-determinadas, promoção de relações de dependência e incompatibilidade com as condições ambientais locais. Esse conjunto de características revela que as ações se pautaram em um enfoque programático marcado pela introdução de repertório técnico padronizado nos sistemas produtivos. Diante disso, as iniciativas de desenvolvimento limitaram a autonomia das famílias beneficiárias ao se distanciarem do enfoque estratégico que orienta o estilo de agricultura dos agroextrativistas.

A organização temática da sentença da jurisprudência como mecanismo de construção da identidade social/profissional do juiz do STF
Authors: Bortoluzzi Valeria Iensen
Published: October 2019

O presente trabalho tem como objetivo apresentar uma análise da metafunção textual (Halliday e Matthiessen, 2004) de um texto de jurisprudência, discutindo como a escolha dos elementos que servirão como tema da oração contribui para a construção da identidade social/profissional de um juiz do Supremo Tribunal Federal, (de acordo com Fairclough, 2001). Os resultados demonstram uma preferência pelo uso de temas marcados, acarretando em apagamento do sujeito (ou colocação do mesmo em segundo plano). Tal atitude revela a construção da identidade do juiz como um ser que se confunde com o Direito, como se ambos formassem um só ser.

Doblemente desaparecidos: servicio militar, pobreza y represión en la frontera patagónica durante la última dictadura argentina
Authors: Mereb Marina Ayelen
Published: October 2019

En las últimas décadas, la lucha de los organismos de derechos humanos en Argentina ha logrado importantes avances judiciales y de políticas públicas vinculadas a la memoria, la verdad y la justicia respecto de las atrocidades cometidas bajo el terrorismo de Estado. Actualmente, asistimos a la pretensión oficial de reinstalar el discurso negacionista, ante lo cual, desde el campo académico, la historia oral y los estudios sobre memorias permiten iluminar aspectos novedosos que demuestran la falacia de dicho discurso, a la vez que enriquecen la mirada sobre ese pasado que no pasa. Desde esta perspectiva, y basado en testimonios orales y documentos de archivo, este artículo aborda el caso de Héctor Domingo Inalef, detenido en El Bolsón por supuesta deserción al servicio militar en 1976 y desde entonces “desaparecido” hasta reencontrarse con su familia en 2014. Hijo mayor y principal sostén económico de una familia mapuche tradicionalmente dedicada al acopio y acarreo de leña, su historia abona la reflexión sobre la desaparición forzada en nuestro país, la superposición de la represión con las marcas de la desigualdad social, y las implicancias políticas y memoriales de la pobreza y la ruralidad en la frontera patagónica, tanto en tiempos dictatoriales como democráticos. Palabras clave: Desaparecidos Políticos.

Este artigo analisa o caso dos jornalistas saneados do jornal Diário de Notícias, no verão de 1975. Iniciado em agosto desse ano, o chamado «caso dos 24» coincide com um dos momentos mais “quentes” do período revolucionário português, em que se intensificam as tentativas de controlo político-ideológico dos meios de comunicação social. Verificamos, entre outras coisas, que, efetivamente, este caso não foi apenas um problema laboral, mas antes um problema que se inseriu num contexto mais vasto: uma luta política que marcou o país entre 1974 e 1975.Palavras-chave: Diário de Notícias.

Memórias, subjetivação e educação no tempo presente: como as representações de violência sexual são abordadas nos livros didáticos de História?
Authors: Oliveira Susane Rodrigues de
Published: October 2019

Este artigo tem como tema as representações de violência sexual nas narrativas de 6 coleções de livros didáticos de História, aprovados pelo Programa Nacional do Livro e do Material Didático (PNLD) de 2018, para o Ensino Médio. Trata-se de representações do passado que se apoiam em um conjunto de memórias de violência sexual, especialmente de estupros em cenários de guerra, colonialismo, escravidão e outros conflitos sociais. Com base em estudos feministas interseccionais, busca-se desvelar a historicidade dessas representações, atentando para abordagens, sentidos, discursos e implicações político-pedagógicas nos processos de subjetivação (de gênero/sexualidade) e na educação dos modos de ver, sentir, interpretar e tratar a violência sexual contra mulheres no tempo presente. Com esse intuito, o artigo também apresenta alguns questionamentos e orientações que podem subsidiar os processos de elaboração dos livros didáticos, bem como as formas de abordagem do tema violência sexual no ensino de História.Palavras-chave: Livros Didáticos.

There is currently a need for proxy measures of the HIV rebound competent reservoir (RCR) that can predict viral rebound after combined antiretroviral treatment (cART) interruption. In this study, macaques infected with a barcoded SIVmac239 virus received cART beginning between 4- and 27 days post-infection, leading to the establishment of different levels of viral dissemination and persistence. Later treatment initiation led to higher SIV DNA levels maintained during treatment, which was significantly associated with an increased frequency of SIV reactivation and production of progeny capable of causing rebound viremia following treatment interruption. However, a 100-fold increase in SIV DNA in PBMCs was associated with only a 2-fold increase in the frequency of reactivation. These data suggest that the RCR can be established soon after infection, and that a large fraction of persistent viral DNA that accumulates after this time makes relatively little contribution to viral rebound.

Background

Because of the complex mechanisms of injury, conventional surgical treatment and early blood pressure control does not significantly reduce mortality or improve patient prognosis in cases of intracerebral hemorrhage (ICH). We aimed to identify the hub genes associated with intracerebral hemorrhage, to act as therapeutic targets, and to identify potential small-molecule compounds for treating ICH.

Methods

The GSE24265 dataset, consisting of data from four perihematomal brain tissues and seven contralateral brain tissues, was downloaded from the Gene Expression Omnibus (GEO) database and screened for differentially expressed genes (DEGs) in ICH, with a fold change (FC) value of (|log2FC|) > 2 and a P-value of <0.05 set as cut-offs. The functional annotation of DEGs was performed using Gene Ontology (GO) resources, and the cell signaling pathway analysis of DEGs was performed using the Kyoto Encyclopedia of Genes and Genomes (KEGG), with a P-value of <0.05 set as the cut-off. We constructed a protein-protein interaction (PPI) network to clarify the interrelationships between the different DEGs and to select the hub genes with significant interactions. Next, the DEGs were analyzed using the CMap tool to identify small-molecule compounds with potential therapeutic effects. Finally, we verified the expression levels of the hub genes by RT-qPCR on the rat ICH model.

Result

A total of 59 up-regulated genes and eight down-regulated genes associated with ICH were identified. The biological functions of DEGs associated with ICH are mainly involved in the inflammatory response, chemokine activity, and immune response. The KEGG analysis identified several pathways significantly associated with ICH, including but not limited to HIF-1, TNF, toll-like receptor, cytokine-cytokine receptor interaction, and chemokine molecules. A PPI network consisting of 57 nodes and 373 edges was constructed using STRING, and 10 hub genes were identified with Cytoscape software. These hub genes are closely related to secondary brain injury induced by ICH. RT-qPCR results showed that the expression of ten hub genes was significantly increased in the rat model of ICH. In addition, a CMap analysis of three small-molecule compounds revealed their therapeutic potential.

Conclusion

In this study we obtained ten hub genes, such as IL6, TLR2, CXCL1, TIMP1, PLAUR, SERPINE1, SELE, CCL4, CCL20, and CD163, which play an important role in the pathology of ICH. At the same time, the ten hub genes obtained through PPI network analysis were verified in the rat model of ICH. In addition, we obtained three small molecule compounds that will have therapeutic effects on ICH, including Hecogenin, Lidocaine, and NU-1025.

Published: October 2019

During the last decade, severalBohaiornis-like enantiornithine species—and numerous specimens—have been recognized from the celebrated Jehol Biota of northwestern China. In this paper, we describe the anatomy of another “bohaiornithid” species from the 125 million-year-old Yixian Formation of Liaoning Province, China. The new taxon differs from previously recognized “bohaiornithids” on a number of characters from the forelimb and shoulder girdle. We also provide a new phylogenetic framework for enantiornithine birds, which questions the monophyly of the previously recognized bohaiornithid clade and highlights ongoing challenges for resolving enantiornithine interrelationships. Additionally, we offer the first assessment of the flight properties ofBohaiornis-like enantiornithines. Our results indicate that while “bohaiornithids” were morphologically suited for flying through continuous flapping, they would have been unable to sustain prolonged flights. Such findings expand the flight strategies previously known for enantiornithines and other early birds.

Background

The canine transmissible venereal tumor (CTVT) or Sticker’s sarcoma is a neoplastic disease affecting dogs. This disease is presented as a tumoral mass in the genital organs of both, male and female individuals. Up to date, there is no clear evidence indicating a viral agent as the causative mediator for CTVT development.

Purpose

The present work aims to analyze 21 samples from canines with CTVT for molecular identification of Papillomavirus DNA sequences. In addition, microbiological analysis, cytologic and histopathologic evaluations were also performed.

Results

All patients showed no biochemical and microbiological alterations. Molecular analysis demonstrated the viral DNA presence in the samples using different primer sets. The MY primers amplified a 450 bp band in seven out of 21 samples (33%). The PVF and Fap64 primer set, targeting the L1 sequence of Canine Papillomavirus (CPV), showed positivity in 16 out of 21 samples (76%).

Conclusion

These results support the possible causative association between CPV and CTVT; nevertheless, additional studies are required to uphold such statement. This work presents evidence indicating that a viral agent might be involved in the pathogenesis of CTVT and set the bases for a better understanding of the CTVT pathobiology.

Published: October 2019

Here, an environmentally‐friendly and scalable process is reported to synthesize reduced graphene oxide (RGO) thin films for printed electronics applications. The films are produced by inkjet printing GO flakes dispersed binder‐free in aqueous solutions followed by treatment with a nonthermal, radio‐frequency (RF) plasma containing only argon (Ar) gas. The plasma process is found to heat the substrate to temperatures no greater than 138 °C, enabling RGO to be printed directly on a wide range of temperature‐sensitive substrate materials including photo paper. Unlike other low‐temperature methods such as electrochemical reduction, plasma reduction is friendly to moisture absorbent materials. Moreover, the plasma treatment can be performed on nonconducting substrates, eliminating the need for film transfer. From an applications perspective, the printed, plasma‐reduced RGO exhibits excellent electrical, mechanical, and electrochemical properties. As a technology demonstrator, the working electrodes of hydrogen peroxide (H2O2) sensors fabricated from plasma‐reduced GO show a sensitivity of 277 ± 80 µA mm−1 cm−2, which is comparable to RGO working electrodes made by electrochemical reduction.
EnantioselectiveLCanalysis and determination of selective serotonin reuptake inhibitors
Authors: Sethi Sonika , Bhushan Ravi
Published: October 2019

LC separation of biologically and pharmaceutically important enantiomers (from racemic or non‐racemic mixtures) remains a subject of importance. The present review article deals with the liquid chromatographic enantioseparation of chiral selective serotonin reuptake inhibitors (SSRIs), namely citalopram, paroxetine, sertraline and fluoxetine. It is now known that the enantiomers of numerous psychotropic drugs exhibit distinct pharmacodynamics, pharmacokinetic patterns and receptor binding properties, and psychiatric patients are frequently taking more than one medication. Therefore, monitoring of the levels of these analytes in biological fluids is important to determine the levels of enantiomer concentrations; the present paper may be helpful in understanding the present state of available methods (along with a critical discussion of applicability of the methods) and in developing the new ones for this purpose. Different approaches using LC discussed herein may be applied for determining the enantiomeric composition (and enantiomeric purity) of SSRIs and numerous other racemic drugs, of current/future pharmaceutical importance and utility, using simple separation methods, instrumentation, inexpensive reagents and potentially significant analytical approaches. The contents cover the essential data to understand the various separation techniques and associated issues, if any, with documented examples.
