Bi-sulphotellurides associated with Pb – Bi – (Sb ± Ag, Cu, Fe) sulphosalts: an example from the Stan Terg deposit in Kosovo
Authors: Kołodziejczyk Joanna , Pršek Jaroslav , Voudouris Panagiotis Ch. , Melfos Vasilios 
Published: August 2017

AbstractNew mineralogical and mineral-chemical data from the Stan Terg deposit, Kosovo, revealed the presence of abundant Bi-sulphotellurides associated with Bi- and Sb-sulphosalts and galena in pyrite–pyrrhotite-rich skarn-free ore bodies (ores without skarn minerals). The Bi-bearing association comprises Bi-sulphotellurides (joséite-A, joséite-B, unnamed phase A with a chemical formula close to (Bi,Pb)2(TeS)2, unnamed phase B with a chemical composition close to (Bi,Pb)2.5Te1.5S1.5), ikunolite, cosalite, Sb-lillianite, members of the kobellite series and Bi-jamesonite. Compositional trends of the Bi-sulphotellurides suggest lattice-scale incorporation of Bi–(Pb)-rich module and/or admixture with submicroscopic PbS layers in modulated structures, or complicated Bi–Te substitution. Cosalite is characterized by high Sb (max. 3.94 apfu), and low Cu and Ag (up to 0.72 apfu of Cu+Ag). Jamesonite from this mineralization has elevated Bi content, from 0.85 to 2.30 apfu. The negligible content of Au and Ag in the Bi-sulphotellurides, the low content of Ag in Bi-sulphosalts, together with the lack of Au–Ag bearing phases in the mineralization, indicate either ore deposition from fluid(s) depleted in precious metals, or physico-chemical conditions of ore formation preventing Au and Ag precipitation at the deposit site. The temperature of initial mineralization may have exceeded 400 °C as suggested by the lamellar exsolution textures observed in lillianite, which indicate breakdown textures from decomposition of high-temperature initial crystals. Non-stoichiometric phases among the Bi-sulphosalts and sulphotellurides studied at Stan Terg reflect modulated growth processes in a metasomatic environment.
Progress in Research on the Mechanism and Treatment of Post-stroke Infection
Authors: Zhang Hongtao 
Published: August 2017

AbstractPost-stroke infection hinders the recovery of stroke patients and can even cause death. The main mechanism of post-stroke infection is related with the post-stroke center, the activation of the peripheral immune system, and the release of inflammatory factors caused by the lesion area and pathophysiological changes in the body. Therefore, elucidating the body’s abnormal immune inflammatory responses after stroke is crucial for the prevention, treatment, and alleviation of post-stroke infection.
Identification of the Disrupted Pathways Associated with Periodontitis Based on Human Pathway Network
Authors: Sun Wen , Han Lin , Xu Wenmao , Sun Yazhen 
Published: August 2017

AbstractObjective: The objective of this work is to search for a novel method to explore the disrupted pathways associated with periodontitis (PD) based on the network level.Methods: Firstly, the differential expression genes (DEGs) between PD patients and cognitively normal subjects were inferred based on LIMMA package. Then, the protein-protein interactions (PPI) in each pathway were explored by Empirical Bayesian (EB) co-expression program. Specifically, we determined the 100th weight value as the threshold value of the disrupted pathways of PPI by constructing the randomly model and confirmed the weight value of each pathway. Meanwhile, we dissected the disrupted pathways under the weight value > the threshold value. Pathways enrichment analyses of DEGs were carried out based on Expression Analysis Systematic Explored (EASE) test. Finally, the better method was selected based on the more rich and significant obtained pathways by comparing the two methods.Results: After the calculation of LIMMA package, we estimated 524 DEGs in all. Then we determined 0.115222 as the threshold value of the disrupted pathways of PPI. When the weight value>0.115222, there were 258 disrupted pathways of PPI enriched in. Additionally, we observed those 524 DEGs that were enriched in 4 pathways under EASE=0.1.Conclusion: We proposed a novel network method inferring the disrupted pathway for PD. The disrupted pathways might be underlying biomarkers for treatment associated with PD.

Authors: Giraldo Liliana , Moreno-Piraján  , Hurtado John J. 
Published: August 2017

AbstractIn this work, the catalytic activity was investigated in the hydrogenation of anthracene by BaSO3and Cu(II), Zn(II) and Ni(II) complexes that contain the ligand bis(3,5-dimethyl-1-pyrazolyl) methane (L). The compounds were supported on activated carbon (AC) and studied as catalysts for the hydrogenation of anthracene over different temperatures and reaction times. The supported catalysts (Cat/AC) were prepared by direct impregnation on the support and characterized by surface area determination, FTIR spectroscopy, and X-ray powder diffraction and pore size distribution analysis. The results showed high conversions and selectivity toward hydrogenated products, where the highest value was obtained using LNiCl2/ACand the lowest with BaSO3/AC. It was established that the selectivity for Tetrahydroanthracene was more highest quantity as a product of hydrogenation using Cat/ACwhich is dependent of the temperature, reaching a peak at 450 °C. At this temperature and with very short reaction times, the catalytic activity is influenced mainly by the chemical characteristics of the metal in the complexes and theACsupport.

Published: August 2017

Abstract
The biological and photocatalytic activity of TiO2 and TiO2:Cu in relation to their structure, surface topography, wettability and optical properties of the thin films was investigated. Thin-film coatings were prepared by magnetron sputtering method in oxygen plasma with use of metallic targets (Ti and Ti-Cu). The results of structural studies revealed that addition of Cu into titania matrix (during the deposition process) resulted in obtaining of an amorphous film, while in case of undoped TiO2, presence of nanocrystalline anatase (with crystallites size of 20 nm) was found. Moreover, an addition of cooper had also an effect on surface diversification and decrease of its hydrophilicity. The roughness of TiO2:Cu film was 25 % lower (0.6 nm) as-compared to titania (0.8 nm). These modifications of TiO2:Cu had an impact on the decrease of its photocatalytic activity, probably as a result of the active surface area decrease. Antibacterial and antifungal properties of the thin films against bacteria (Enterococcus hirae, Staphylococcus aureus, Bacillus subtilis, Escherichia coli) and yeast (Candida albicans) were also examined. For the purpose of this work the method dedicated for the evaluation of antimicrobial properties of thin films was developed. It was revealed that Cu-additive has a positive impact on neutralization of microorganisms.

The Visegrád Group as a Vehicle for Promoting National Interests in the European Union: The Case of the Czech Republic
Authors: Neuman Marek 
Published: August 2017

Abstract
This contribution asks whether sub-regional integration projects such as the Visegrád Group may be understood as mechanisms for pursuing one Group member’s national interests while it stands at the European Union’s helm. I assess this question based on the case of the first Visegrád Group member to assume the EU Council presidency: the Czech Republic. Examining three specific policy areas – the reinvention of the EU’s Eastern neighbourhood policy; the strengthening of EU energy security; and the incorporation of a stronger human rights and external democratisation approach into EU foreign policy – this case study presents a mixed picture. It confirms the potential of the Visegrád Group to be a vehicle for furthering the national preferences of one Group member while it holds the rotating EU Council presidency. Whether or not this potential is fully realised will depend primarily on the degree to which the interests of the four Visegrád countries converge.

AbstractEncapsulation offers broad scope of applications. It can be used to deliver almost everything from advanced drugs to unique consumer sensory experiences; it could be also employed as a protection system or a sensing material. This cutting-edge technology undergoes rapid growth in both academic and industrial conditions. Research in this matter is continuing to find a new application of microcapsules as well as to improve the methods of their fabrication. Therefore, in this review, we focus on the art of the encapsulation technology to provide the readers with a comprehensive and in-depth understanding of up-to-day development of microcapsule preparation methods. Our goal is to help identify the major encapsulation processes and by doing so maximize the potential value of ongoing research efforts.
Natural and synthetic polymers in fabric and home care applications
Authors: Paderes Monissa , Ahirwal Deepak , Fernández Prieto Susana 
Published: August 2017

AbstractPolymers can be tailored to provide different benefits in Fabric & Home Care formulations depending on the monomers and modifications used, such as avoiding dye transfer inhibition in the wash, modifying the surface of tiles or increasing the viscosity and providing suspension properties to consumer products. Specifically, the rheology modification properties of synthetic and natural polymers are discussed in this chapter. The choice of a polymeric rheology modifier will depend on the formulation ingredients (charges, functional groups), the type and the amount of surfactants, the pH and the desired rheology modification. Natural polymeric rheology modifiers have been traditionally used in the food industry, being xanthan gum one of the most well-known ones. On the contrary, synthetic rheology modifiers are preferably used in paints & coats, textile printing and cleaning products.
After Nerve Injury, Lineage Tracing Shows That Myelin and Remak Schwann Cells Elongate Extensively and Branch to Form Repair Schwann Cells, Which Shorten Radically on Remyelination

Published: August 2017

There is consensus that, distal to peripheral nerve injury, myelin and Remak cells reorganize to form cellular columns, Bungner's bands, which are indispensable for regeneration. However, knowledge of the structure of these regeneration tracks has not advanced for decades and the structure of the cells that form them, denervated or repair Schwann cells, remains obscure. Furthermore, the origin of these cells from myelin and Remak cells and their ability to give rise to myelin cells after regeneration has not been demonstrated directly, although these conversions are believed to be central to nerve repair. Using genetic lineage-tracing and scanning-block face electron microscopy, we show that injury of sciatic nerves from mice of either sex triggers extensive and unexpected Schwann cell elongation and branching to form long, parallel processes. Repair cells are 2- to 3-fold longer than myelin and Remak cells and 7- to 10-fold longer than immature Schwann cells. Remarkably, when repair cells transit back to myelinating cells, they shorten ∼7-fold to generate the typically short internodes of regenerated nerves. The present experiments define novel morphological transitions in injured nerves and show that repair Schwann cells have a cell-type-specific structure that differentiates them from other cells in the Schwann cell lineage. They also provide the first direct evidence using genetic lineage tracing for two basic assumptions in Schwann cell biology: that myelin and Remak cells generate the elongated cells that build Bungner bands in injured nerves and that such cells can transform to myelin cells after regeneration.SIGNIFICANCE STATEMENTAfter injury to peripheral nerves, the myelin and Remak Schwann cells distal to the injury site reorganize and modify their properties to form cells that support the survival of injured neurons, promote axon growth, remove myelin-associated growth inhibitors, and guide regenerating axons to their targets. We show that the generation of these repair-supportive Schwann cells involves an extensive cellular elongation and branching, often to form long, parallel processes. This generates a distinctive repair cell morphology that is favorable for the formation of the regeneration tracks that are essential for nerve repair. Remyelination, conversely, involves a striking cell shortening to form the typical short myelin cells of regenerated nerves. We also provide evidence for direct lineage relationships between: (1) repair cells and myelin and Remak cells of uninjured nerves and (2) remyelinating cells in regenerated nerves.
Polycomb and Trithorax Group Genes in Drosophila
Authors: Kassis Judith A , Kennison James A , Tamkun John W 
Published: August 2017

Abstract
Polycomb group (PcG) and Trithorax group (TrxG) genes encode important regulators of development and differentiation in metazoans. These two groups of genes were discovered in Drosophila by their opposing effects on homeotic gene (Hox) expression. PcG genes collectively behave as genetic repressors of Hox genes, while the TrxG genes are necessary for HOX gene expression or function. Biochemical studies showed that many PcG proteins are present in two protein complexes, Polycomb repressive complexes 1 and 2, which repress transcription via chromatin modifications. TrxG proteins activate transcription via a variety of mechanisms. Here we summarize the large body of genetic and biochemical experiments in Drosophila on these two important groups of genes.
Educational Progress of Looked-After Children in England: A Study Using Group Trajectory Analysis
Authors: Sutcliffe Alastair G. , Gardiner Julian , Melhuish Edward 
Published: August 2017

BACKGROUND:
Looked-after children in local authority care are among the most disadvantaged, and measures of their well-being, including educational outcomes, are poorer than other children’s.

METHODS:
The study sample consisted of all children in England born in academic years 1993 to 1994 through 1997 to 1998 who were in local authority care at any point during the academic years 2005 to 2006 through 2012 to 2013 and for whom results of national tests in literacy and numeracy were available at ages 7, 11, and 16 (N = 47 500).

RESULTS:
Group trajectory analysis of children’s educational progress identified 5 trajectory groups: low achievement, late improvement, late decline, predominant, and high achievement. Being looked after earlier was associated with a higher probability of following a high achievement trajectory and a lower probability of following a late decline trajectory. For children first looked after between ages 7 and 16, having a longer total time looked after by age 16 was associated with a higher probability of following a high achievement trajectory. For children with poor outcomes at ages 7 and 11, being looked after by age 16 was associated with an increased chance of educational improvement by age 16.

CONCLUSIONS:
This study provides evidence that early entry into care can reduce the risk of poor educational outcomes. It also establishes group trajectory analysis as an effective method for analyzing the educational progress of looked-after children, with the particular strength that it allows factors associated with a late decline or improvement in educational progress to be identified.

Published: August 2017

An eco-epidemiological model consisting of a three-species food web model, with an
SIS epidemic disease in the intermediate predator, is proposed and analyzed. It is assumed that the disease transmitted between the individual of intermediate predator species only through an external factors as well as contact. The existence, uniqueness and boundedness of the solution of the system are studied. The existence of all possible equilibrium points are discussed. The local as well as global stability analysis of each equilibrium point is investigated. Finally further investigations for the global dynamics of the proposed system are carried out with the help of numerical simulations. It is observed that the system has one type of attractors, its approaches asymptotically to one of its equilibrium points.
A Teoria dos Blocos Semânticos em revisão
Authors: Machado Julio Cesar 
Published: August 2017

Resumo: A Teoria dos Blocos Semânticos ocupa lugar significativo nos trabalhos em Semântica, Argumentação e Enunciação, entre outros, em todo o mundo. Por isso sua pertinência para a Linguística reclama uma reflexão profunda. O presente trabalho analisa algumas reformulações feitas nessa teoria nas últimas duas décadas, a saber: (a) polifonia, (b) bloco semântico, e (c) quadrado argumentativo. Especificamente, trata das seguintes relações: (a’) da Teoria Polifônica da Enunciação à Teoria Argumentativa da Polifonia; (b’) do bloco semântico ao quase-bloco; e (c’) do quadrado argumentativo ao cubo argumentativo. A necessidade deste trabalho é duplamente justificada: (i) devido à constante revisão teórica do arcabouço deste saber, sobretudo na sua última década, característica de Marion Carel e de Oswald Ducrot; e (ii) pela falta de tradução/circulação no Brasil de obras fundamentais no que tange à reelaboração das noções chaves desta teoria.Palavras-chave: polifonia; quase-bloco; cubo argumentativo.Abstract: The Theory of Semantic Blocks occupies an internationally significant place in Semantics, Argumentation and Enunciation, among other fields. Therefore, its relevance to Linguistics should lead to some reflection. This study intends to evaluate some reformulations in the Theory of Semantic blocks that have taken place in the past two decades, namely on the following concepts: (a) polyphony, (b) Semantic block, and (c) argumentative square. Specifically, this paper approaches the following relationships: (a’) from the Polyphonic Theory of Enunciation to the Argumentative Theory of Polyphony; (b’) from the Semantic Block to the Semi-block; and (c’) from the argumentative square to the argumentative cube. The necessity for the reported research results is doubly justified given: (i) the constant theoretical review of this approach framework, especially in the last decade, by Marion Carel and Oswald Ducrot; and (ii) the lack of translations and widespread knowledge in Brazil of fundamental reference pieces dealing with the re-elaboration of key concepts in this theory.Keywords: polyphony; quasi-bloc; argumentative cube.
A morte estampada nas capas de jornais: uma análise semiótica do Massacre de Realengo
Authors: Gama Raiane Nogueira , Mancini Renata 
Published: August 2017

Resumo: A cobertura jornalística de fatos de forte apelo emocional, como mortes trágicas e/ou violentas, suscita uma importante reflexão acerca dos limites entre o que se considera um modo de noticiar moderado ou sensacionalista. O estabelecimento de categorizações duras entre os dois perfis editoriais pode ser frágil. A fim de verificar essa hipótese, este trabalho analisa como doze jornais impressos brasileiros repercutiram o caso conhecido como “Massacre de Realengo” nas capas do dia seguinte ao fato. No episódio, doze estudantes de uma escola municipal da cidade do Rio de Janeiro foram assassinados por um ex-aluno, que se matou em seguida. A análise semiótica permitiu a identificação de marcas textuais e apelos estéticos característicos do jornalismo dito sensacionalista em todos os veículos examinados. Além disso, possibilitou observar a proximidade de O Globo ao polo mais apelativo de um continuum traçado com as capas, em uma gradação qualitativa de efeitos de sentido. O posicionamento do veículo, reconhecido no mercado por adotar um perfil de maior sobriedade, configurou uma quebra de expectativa. Os resultados mostraram que as fronteiras nítidas entre os estilos enunciativos moderado e sensacionalista se desfazem na dimensão pragmática e complexa da práxis jornalística.Palavras-chave: Massacre de Realengo; semiótica francesa; jornalismo; sensacionalismo. Abstract: The press coverage of facts with strong emotional appeal, such as tragic and/or violent deaths, raises an important discussion about the limits between what is considered a moderated or a sensationalist mode of reporting. The establishment of clear-cut boundaries between both editorial profiles can be fragile. In order to verify this hypothesis, this article analyses twelve different approaches of Brazilian newspaper front pages depicting the case known as the “Realengo’s Massacre” in the next day of the fact. In the episode, twelve schoolchildren of a municipal school in the city of Rio de Janeiro were murdered by an ex-student who ended up shooting himself. The semiotic analysis here presented allowed the identification of text marks and aesthetic appeals of the journalism called sensationalist in all examined newspaper covers. It was surprising to observe the proximity of O Globo − a mainstream well established newspaper in Brazil − to the most appellative pole of the continuum traced with all front pages, in a qualitative gradation of meaning effects. This position set up an expectation break, since the newspaper is recognized by its somehow moderate profile. The results showed that the clear-cut boundaries between moderated and sensationalist enunciation styles fall apart in the pragmatic and complex dimension of the journalistic praxis.Keywords: Realengo’s Massacre; discursive semiotics; journalism; sensationalism.
