Application of Biomarkers for Risk Stratification in Patients with Atrial Fibrillation
Authors: Hijazi Ziad , Oldgren Jonas , Siegbahn Agneta , Wallentin Lars 
Published: November 2016

Abstract

BACKGROUND
Atrial fibrillation is the most common sustained arrhythmia and an important contributor to cardiovascular morbidity and mortality. Several strategies have been proposed for prediction of outcomes and individualization of treatments to better balance the benefits of stroke prevention and risks of bleeding during anticoagulation.

CONTENT
The availability of analytically more specific and sensitive methods to measure circulating biomarkers of cellular and organ stress and dysfunction has led to testing of their utility in several cardiovascular conditions. In patients with atrial fibrillation, biomarkers of myocardial injury (troponin) and cardiovascular stress and dysfunction (natriuretic peptides, growth differentiation factor 15), myocardial fibrosis (galectin-3), renal dysfunction (creatinine, cystatin C), inflammation (C-reactive protein, cytokines) and coagulation activity (d-dimer) have been found associated with underlying pathophysiology, clinical outcomes and effects of treatment. Measurements of these markers might therefore expand the understanding of the pathophysiology, improve risk assessment and optimize treatment in individual patients with atrial fibrillation.

SUMMARY
Biomarkers for risk stratification have potential roles as tools for evaluation of patients with atrial fibrillation and for selection of the best treatment strategies to prevent stroke, major bleeding, and mortality.

Abstract

BACKGROUND
We have previously demonstrated the utility of a rule-in/rule-out strategy for myocardial infarction (MI) using glycemic biomarkers in combination with cardiac troponin in the emergency department (ED). Given that the cost of assessing patients with possible MI in the ED is increasing, we sought to compare the health services cost of our previously identified early rule-in/rule-out approaches for MI among patients who present to the ED with symptoms suggestive of acute coronary syndrome (ACS).

METHODS
We compared the cost differences between different rule-in/rule-out strategies for MI using presentation cardiac troponin I (cTnI), high-sensitivity cTnI (hs-cTnI), high-sensitivity cardiac troponin T (hs-cTnT), glucose, and/or hemoglobin A1c (Hb A1c) in 1137 ED patients (7-day MI n = 133) as per our previously defined algorithms and compared them with the European Society of Cardiology (ESC) 0-h algorithm-cutoffs. Costs associated with each decision model were obtained from site-specific sources (length of stay) and provincial sources (Ontario Case Costing Initiative).

RESULTS
Algorithms incorporating cardiac troponin and glucose for early rule-in/rule-out were the most cost effective and clinically safest methods (i.e., ≤1 MI missed) for early decision making, with hs-cTnI and glucose yielding lower costs compared to cTnI and glucose, despite the higher price for the hs-cTnI test. The addition of Hb A1c to the algorithms increased the cost of these algorithms but did not miss any additional patients with MI. Applying the ESC 0-h algorithm-cutoffs for hs-cTnI and hs-cTnT were the most costly.

CONCLUSIONS
Rule-in/rule-out algorithms incorporating presentation glucose with high-sensitivity cardiac troponin are the safest and most cost-effective options as compared to the ESC 0-h algorithm-cutoffs.

Abstract

BACKGROUND
Rapid rule-out strategies using high-sensitivity cardiac troponin assays are largely supported by studies performed outside the US in selected cohorts of patients with chest pain that are atypical of US practice, and focused exclusively on ruling out acute myocardial infarction (AMI), rather than acute myocardial injury, which is more common and associated with a poor prognosis.

METHODS
Prospective, observational study of consecutive patients presenting to emergency departments [derivation (n = 1647) and validation (n = 2198) cohorts], where high-sensitivity cardiac troponin I (hs-cTnI) was measured on clinical indication. The negative predictive value (NPV) and diagnostic sensitivity of an hs-cTnI concentration &lt;limit of detection (LoD) at presentation was determined for acute myocardial injury and for AMI or cardiac death at 30 days.

RESULTS
In patients with hs-cTnI concentrations &lt;99th percentile at presentation, acute myocardial injury occurred in 8.3% and 11.0% in the derivation and validation cohorts, respectively. In the derivation cohort, 27% had hs-cTnI &lt; LoD, with NPV and diagnostic sensitivity for acute myocardial injury of 99.1% (95% CI, 97.7–99.8) and 99.0% (97.5–99.7) and an NPV for AMI or cardiac death at 30 days of 99.6% (98.4–100). In the validation cohort, 22% had hs-cTnI &lt;LoD, with an NPV and diagnostic sensitivity for acute myocardial injury of 98.8% (97.9–99.7) and 99.3% (98.7–99.8) and an NPV for AMI or cardiac death at 30 days of 99.1% (98.2–99.8).

CONCLUSIONS
A single hs-cTnI concentration &lt;LoD rules out acute myocardial injury, regardless of etiology, with an excellent NPV and diagnostic sensitivity, and identifies patients at minimal risk of AMI or cardiac death at 30 days. ClinicalTrials.gov Identifier: NCT02060760

Ser ou não ser bilíngue: Os posicionamentos subjetivos de uma professora de inglês diante do Outro
Authors: Franco Arabela Vieira dos Santos Silva 
Published: November 2016

As propostas da linguística para categorizar um indivíduo como bilíngue formam um espectro de possibilidades, e para torná-lo ainda mais extenso, uma abordagem psicanalítica nos oferece a possibilidade de tratarmos o tema pelo viés da singularidade, analisando como cada sujeito se inscreve discursivamente como sujeito bilíngue. Visto que me filio, aqui, ao pressuposto de que é no discurso, na relação com o Outro, que esse sujeito irá se constituir, temos que não haverá significantes que se esgotem para defini-lo como bilíngue. O corpus foi formado utilizando a metodologia dos Conversational rounds e a análise dos dizeres foi feita à luz das teorias da significação e dos quatro discursos esquematizadas por Lacan. Apresento alguns dizeres de uma professora a respeito do tema bilinguismo, destacando sua relação com a fala em língua inglesa. Pude observar giros discursivos, mas não constatei nenhum deslocamento subjetivo da professora em relação ao seu posicionamento como sujeito bilíngue, ou em relação à habilidade da fala. O principal resultado dessa pesquisa foi perceber que a definição de um sujeito bilíngue ultrapassa a singularidade de uma possível classificação para cada sujeito, uma vez que a cada giro discursivo o sujeito pode se dizer ou se colocar como sendo ou não bilíngue. Portanto, qualquer tentativa de significar o sujeito será tão evanescente quanto seus posicionamentos nos discursos. Este estudo contribui, assim, para que se considere o impossível na lida com as línguas e o modo singular como cada um lida com sua falta.
Development of a WSN for Greenhouse Microclimate Distribution Monitoring

Published: November 2016

Abstract
Precision greenhouse agriculture requires several measuring points in order to have a better overview of the whole cultivation area. Climate variability within the covered area of a greenhouse can result in a non-uniform plant development and reduced productivity. Therefore, a distributed system, capable of taking multi-point measurements would be able to catch the climatic gradients in order to provide growers with a more detailed depiction of the climate at any time and early warnings of potential threats. Furthermore, the distributed monitoring can offer the appropriate inputs to more sophisticated distributed or plant-based climate control algorithms. The significant price drop in embedded computer and wireless communication chips, as well as the overall maturity of the available, low-power platforms have made the deployment of Wireless Sensor Networks increasingly attractive in modern agricultural facilities. This paper presents a Wireless Sensor Network (WSN) deployed for long periods in commercial facilities, equipped with shading screens and cooling pads placed in different directions, namely vertically to the plantation and parallel to it. The evolution of the various climate parameters in both greenhouses and the effect of the climate on the plants and the wireless communications are analyzed and presented.

Researches About the Influence of Reducing the Assimilation Surface on Number of Grains/Cob Corn at Some Maize Hybrids
Authors: David Ivona 
Published: November 2016

Abstract
In this work it was analyzed the influence of reducing leaves surface on the number of grains/cob corn at four maize hybrids created at The National Institute for Researches and Development Fundulea. The results show that in the phenological phase of formation of stigmata, at studied hybrids, the most important factor which influenced the number of grains/cob corn were the last three leaves under panicle. On average, leaf removal produced losses in the number of grains /cob corn compared with the control values for all variants tested. Losses ranged between 12 and 26% compared to the control variant. The most obvious reduction in the number of grains / cob corn for analyzed hybrids were recorded in the variant where the leaves are removed from the top of the corn cob and remained only the leaf under the panicle. (74 % of control). In phenological phase of 15 days after stigmata formation, the lowest value of this character was recorded in experimental version which have been removed all the leaves above the cob corn, respectively 80 % of controls, and the maximum value of the analyzed hybrids was registered in experimental version which have been removed all the leaves below the corn cob.
Facilitation Fish Migration above the Discharge Sill Located on the Ialomiţa River Near Cave Ialomicioara
Authors: Voicu Răzvan , Dominguez Lawrence G. 
Published: November 2016

Abstract
Longitudinal connectivity restoration of watercourses is a major duty for scientists (biologists, hydro engineers, chemists etc.) that, by the means of technical exchange via conferences, projects, workshops, universities, and institutions demonstrate the major importance of a natural (non-anthropic) function of the lotic ecosystems. On the Ialomiţa River, the discharge sills located downstream from Padina chalet block the migration of some fish species, such as the brown trout (Salmo trutta) and the bullhead (Cottus gobio), prohibiting access to foraging areas and springs. Water Framework Directive 60/2000 / EC provides a legal framework for restoring “good status” of longitudinal and lateral connectivity of watercourses. Our proposed solution I can be applied to other discharge sills and dams sized between 3m and 6m high, and, where feasible can utilize existing power sources of some discharge sills. Solution II’s concepts allow the dimples inside the concrete plate to serve as a rest and recovery area for migratory species. Such benefits that ensure upstream/downstream fish migration while allowing discharge management to continue is unattainable in conventional systems. After solution II is applied the discharge sill does not lose any baseline characteristics while maintaining the original hydro-technical design objective, flood dissipation.
Socioeconomic Valences of the Human Settlements in Tecuci Plain in the Context of Sustainable Development
Authors: Stănilă Cristian , Barbu Oana Nicoleta 
Published: November 2016

Abstract
In conducting the scientific endeavor we started from the assumption that directing the efforts of local communities based on the principles of sustainable development, the degree of socio-economic development of the Tecuci Plain will be improved in a time span of 25-30 years. The development of the plain is below its potential but it presents viable resources that can lead to the shaping of sustainable development strategies applicable at territorial level. The various works consulted point out that the sustainable development of an area requires a complex precede that provides the analysis of all factors which can influence human settlements’ development of perspective. In this sense it entails identifying the natural conditions of the Tecuci Plain and how they are reflected by the socio-economic development of human settlements, knowing that this space is identified at regional and national level as an important agricultural center that utilizes rationally the land. The quintessence that can accelerate the sustainable development of the territory is given by the accessibility to the local and regional context of the Tecuci Plain. Accessibility is also a prerequisite in establishing a network of centers polarizing localities that maintain functional interdependencies and diffusion of services across sectors. The knowledge of space and disorders diagnosing are absolutely necessary for integrating development policies to implement the phenomenon of territorial, social and economic cohesion. Rural settlements of the Tecuci Plain radiate around the only urban center, the city of Tecuci, center that tries to regain its identity and its importance by channeling efforts to promote agricultural products in the region, given that the secondary and tertiary sectors fail to gain ground in front of the basic occupation of 60% of the administrative units that are part of the plain. The rural component from the Tecuci Plain is actually a whole scale (system) “built” on a macro scale with three elements (subsystems): the physical subsystem (environmental and natural conditions), the social subsystem (rural population and habitat rural) and economical subsystem (external physical environment transformed by the rural population).
Phototextuality as a Phenomenon of Present-Day British Prose
Authors: Sudliankova Volha 
Published: November 2016

Abstract
Like many other world literatures, the English literature of the last few decades has been marked by an intensive search for new narrative techniques, for innovative ways and means of arranging a plot and portraying characters. The search has resulted, among other things, into merging literature with visual arts like painting, film and photography. This phenomenon got the name of ekphrasis and has become a popular field of literary research lately.
Suffice it to cast a glance at several of the novels published around the year 2000 to see that incorporation of photographic images into fiction allows writers to use new means of organizing literary texts, to employ non-conventional devices of structuring a plot and delineating personages as well as to pose various problems of aesthetic, ethical, ideological nature.
We suggest to look briefly at seven novels published in the last three decades to see the various roles assigned to photography by their authors: Out of this World (1988) by Graham Swift, Ulverton (1992) by Adam Thorpe, Master Georgie (1998) by Beryl Bainbridge, The Dark Room (2001) by Rachel Seiffert, The Photograph (2003) by Penelope Lively, Double Vision (2003) by Pat Barker and The Rain Before It Falls (2007) by Jonathan Coe.
The scenes of the novels are set widely apart and have time spans of various duration. Ulverton and Master Georgie have a mid-19th century setting, The Dark Room is centered round WWII, Out of this World and The Rain before It Falls contain their heroes’ long life stories, while The Photograph and Double Vision are set at the end of the last century and their characters are our contemporaries. The novels also differ by the particular place photographs occur in the novels, by the roles they play there, as well as by the issues associated with them.
Popularization and/or Trivialization of Philosophy in Voltaire's Narrative Candide or Optimism
Authors: Majksner Ivana , Oswald Tina Varga 
Published: November 2016

Abstract
Voltaire produced his works within the literary-historical period of Classicism and Enlightenment, in which the prevalent role of literature was educational. The period also dictated what genre, theme, style and structure authors should follow. However, more and more changes of literary genres appear, and the process of stratification of literature into high and trivial takes place. The aim of this paper is to describe the polarization of two mutually different processes involved in the literary shaping of Voltaire's philosophical narrative Candide or Optimism. In Voltaire's narrative, the popularization of philosophy, in order to simplify and illuminate the philosophical writings of G. W. Leibniz, results in the changes of style and content that become understandable to the general readership since they work within the scheme of an adventure novel. In this process, trivialization does not affect only the genre, but is also present in other parts of literary analysis and interpretation such as the theme, motifs, structure, characterization, narrative techniques, stylistic features, and so on.

Abstract
It is shown that voting procedure in any authority
can be treated as Hopfield neural network analogue.
It was revealed that weight coefficients of neural network
which has discrete outputs −1 and 1 can be replaced by coefficients
of a discrete set (−1, 0, 1). This gives us the opportunity
to qualitatively analyze the voting procedure on the
basis of limited data about mutual influence of members. It
also proves that result of voting procedure is actually taken
by network formed by voting members.
Taxonomic diversity of cockroach assemblages (Blattaria, Insecta) of the Aptian Crato Formation (Cretaceous, NE Brazil)
Authors: Lee Shih-Wei 
Published: November 2016

AbstractA comprehensive revision of 981 specimens of fossil cockroaches from the Lower Cretaceous laminated limestones of the Crato Formation of Northeast Brazil shows that they belong to eleven taxa, includingPiniblattella limai,P. magnasp. n.,Perlucipecta santanensis.sp. n.,Raptoblatta waddingtonae;Ocelloblattula santanensissp. n.,Elisama brevis(=E. americana, syn.n.),E. hindwingniisp. n.,Ponopterix axelrodi(=P. maximasyn.n.),Umenopterix burkhardicomb. n., andCratovitisma oldreadi(Umenocoleidae = Cratovitismidae syn.n. = Ponopterixidae syn.n.). The family Ectobiidae is numerically most abundant in the assemblage of cockroaches of the Crato Formation (83 % of cockroaches), followed by Blattulidae (13 %) and Umenocoleidae (4 %). 79.2 % of specimens are complete and fully articulated. Members of the family Alienopteridae are probably also present. Representatives of a relatively common Mesozoic superfamily Caloblattinoidea are missing. With the exception of the endemic generaCratovitismaandRaptoblattaand the exclusively Gondwanan genusOcelloblattula, all other genera were cosmopolitan. Taxonomic richness of cockroaches of the Crato Formation is thus rather low, and consists of geologically long-ranging and geographically-widespread genera, genera restricted to Gondwana, and short-ranging endemic genera found in the Crato Formation only.
