Many environmental contaminants are introduced via the diet and may act as neurotoxins and endocrine disrupters, especially influencing growing organisms in early life. The purpose of this study was to examine whether dietary exposure of dams to fish naturally contaminated with xenobiotics, especially with polychlorinated biphenyls (PCBs) and heavy metals (e.g. mercury and lead), resulted in cognitive function deficits in adult offspring mice. Daily, four groups of dams (n = 10/group) ingested standard diet plus paste with/without eels, during gestation and lactation, from gestational day (GD) six until post natal day (PND) 21 (weaning). Dams orally ingested a standardized amount of eel (0.8 mgkg-1 d-1) containing the six non-dioxin-like (NDL) PCBs (σ6 NDL-PCBs: 28, 52, 101, 138, 153, and 180) at 0, 85, 216, and 400 ngkg-1 d-1. Results showed that early-life exposure to contaminated eels did not (compared to non-exposed controls) impair immediate working memory in the Y-maze in the offspring assessed at PND 38. Furthermore, it did not significantly impact spatial learning and retention memory as measured in the Morris water maze in adult offspring mice (PND 120-123). Our results suggest that perinatal exposure to contaminated eels does not affect spatial cognitive performances, as assessed by the Y-maze and Morris water maze at adult age. Adverse effects of xenobiotics reported earlier might be camouflaged by beneficial eel constituents, such as n-3 fatty acids. However, additional studies are needed to differentiate between potential positive and negative effects following consumption of food items both rich in nutrients and contaminants. © 2014 Elsevier Inc.

INTRODUCTION: Cardiopathies are the world's leading cause of mortality and morbidity. Although rare, cardiovascular accidents can occur during intense and infrequent sporting activity, particularly among those who are unaware of their heart condition. The development of cardiospecific biochemical markers has led to a reconsideration of the role of biology in the diagnosis of cardiovascular illnesses. The aim of this study therefore was, through the use of cardiac biomarker assays, to highlight the impact of sustained physical effort in the form of intense and prolonged concentric isokinetic exercise and to research potential cardiovascular risks. MATERIALS AND METHODS: Eighteen subjects participated in a maximal concentric isokinetic exercise involving 30 knee flexion-extensions for each leg. Five blood tests were taken to study the kinetics of the cardiac biomarkers. Haemodynamic parameters were measured continuously using a Portapres, and respiratory parameters were measured using a Sensormedics Vmax 29C. RESULTS: The results showed significant increases in the creatine kinase, myoglobin, homocysteine and haemoglobin cardiac markers. Evolutionary trends were also observed for the following biomarkers: NT-proBNP, myeloperoxydase and C-reactive protein. All the physiological parameters measured presented statistically significant changes. CONCLUSION: Isokinetic effort leads to the release of cardiac markers in the blood, but these do not exceed the reference values in healthy subjects. Maximal concentric isokinetic exercise does not, therefore, lead to an increased risk of cardiovascular pathologies. [less ▲]

This paper aims at studying the effect of corporate disclosures on information asymmetry and stock-market liquidity in France. Specifically, the purpose of this paper is to highlight the importance of information included in the annual reports on investor’s behavior. This is proxied by the information asymmetry component of the bid-ask spread and stock market liquidity. Our sample includes 196 French listed firms over a period ranging from 2004 to 2007. We opt for an explanatory study using OLS regressions to examine the nature of the relationship between information disclosed in annual reports and bid-ask spreads a proxy for information asymmetry and stock market liquidity. The results show that the extent of corporate disclosures in annual reports positively influences the liquidity of the French market and negatively affects the adverse selection component of the bid-ask spread. This effect is further confirmed by the commitment to IFRS by French-listed firms from 2005. The decomposition of the total score in the sub-indices shows that non-financial and financial information are important in trading decisions while strategic information may be attractive only for long-term positions [less ▲]

En 140/39 av. J.-C., une mission romaine composée, entre autres, de Scipion Emilien et du philosophe Panétios visita les alliés orientaux de Rome et se rendit notamment à Alexandrie. Le roi Ptolémée VIII y accueillit officiellement ces hôtes prestigieux, vêtu d’un habit étrange : un chiton long et subtil, dont les auteurs anciens réfèrent unanimement l’effet efféminé et caricatural, au point de susciter le rire des Romains et une condamnation du luxe effréné et décadent du royaume égyptien par comparaison avec la sobriété romaine. Il a fallu attendre une étude de H. Heinen en 1983 pour reconnaître, d’une part, l’envergure idéologique du lien entre la tenue de Ptolémée VIII – en fait empruntée à l’iconographie hellénistique de Dionysos – et la mise en scène officielle de la tryphè et du pouvoir royal et, de l’autre, le sens politique de la représentation caricaturale qu’en donna probablement déjà Panétios, représentation qui fut relayée et amplifiée par toute une tradition historiographique philo-romaine, qui se développa tout au long de la conquête romaine de la Méditerranée et ensuite à l’occasion du conflit entre Octavien et Antoine. Cette tradition nous a transmis, par le biais des auteurs de l’époque impériale, un discours fondé sur l’opposition entre Rome (et l’Italie), vertueuse source de citoyens et de soldats, et l’Orient dégénéré. Dans un tel cadre, Dionysos et le dionysisme sont sollicités pour servir à la construction d’un modèle accusatoire contre les ennemis de Rome, incarnant le désordre dans une dimension à la foi individuelle et institutionnelle. Mais est-ce que cette vision idéologique nous donne un portrait satisfaisant des rapports réels entre Rome et Dionysos / Bacchos / Liber Pater ? En partant de cette question, je propose dans ma contribution une approche visant à analyser, à l’aide de sources aussi littéraires que documentaires, les contextes de contact entre Rome et Dionysos de l’époque hellénistique au début du Principat, pour essayer de mettre en relief les relations entre, d’une part, la répulsion et le refus idéologiques du dionysisme, de l’autre les démarches d’appropriation et d’adaptation, à la culture romaine, de traits caractérisant les cultes hellénistiques de Dionysos et leurs utilisation dans la mise en forme des pratiques du pouvoir et de leurs représentations.

This article proposes to apply Steen’s (2008) 3D model of metaphor analysis in communication to a corpus of political discourse, in this case citizen discourse. Our corpus has accordingly been analysed by making a distinction between three layers of metaphor, respectively at the linguistic (direct vs. indirect metaphors), conceptual (novel vs. conventional metaphors) and communicative levels (deliberate vs. non-deliberate metaphors). Our results suggest that making the distinction between deliberate and non-deliberate metaphors lead to meaningful political insights, notably pointing to differences in saliency of the source domains in terms of which citizens make sense of Belgian federalism. In this regard, the family domain, and more especially the metaphor BELGIAN FEDERALISM IS A LOVE RELATIONSHIP appears to function as an important conceptual reference point for the citizens’ understanding of the political relations in the Belgian context.

Scientists in many fields of research have developed models, theories and concepts attempting to grasp and manage dangers that are often difficult to imagine. Among the different perspectives, the Science and Technology Studies (STS) Vulnerability Approach seems very promising. Relying on a constructivist paradigm, it is based on an inductive collection and analysis of a wide range of factors, with a particular focus on cultural factors and actual day-to-day practices. In this paper, we present the roots of this approach and we display findings based on three case studies exploring emergency planning in three different contexts (a city near a SEVESO plant, a school near a nuclear plant, and a city confronted to multiple catastrophic scenarios). The cases studies were realized by conducting three Focus Groups with different types of stakeholders (citizens, teachers, firemen, decision makers, etc.). After presenting the results of the case studies, we discuss how stakeholders’ participation can inform such type of vulnerability analysis in the context of emergency planning. We argue that participation fosters a deep understanding of actual safety governance practices which allows innovative results to emerge as well as it initiates a learning process among the participants. It contributes to questioning the relations between decision-makers, experts and citizens. It has the potential of bypassing the positivist and quantitative rationale of safety, and thus, of redefining the vulnerability governance. As a conclusion, we question the role of such STS vulnerability approach within the actual vulnerability governance. [less ▲]

We report bulk gas concentrations of O2, N2 and Ar, as well as their transport coefficients, in natural landfast subarctic sea ice in southwest Greenland. The observed bulk ice gas composition was 27.5% O2, 71.4% N2 and 1.09% Ar. Most previous studies suggest that convective transport is the main driver of gas displacement in sea ice and have neglected diffusion processes. According to our data, brines were stratified within the ice, so that no convective transport could occur within the brine system. Therefore, diffusive transport was the main driver of gas migration. By analysing the temporal evolution of an internal gas peak within the ice, we deduced the bulk gas transport coefficients for oxygen (DO2), argon (DAr) and nitrogen (DN222 ). The values fit to the few existing estimates from experimental work, and are close to the diffusivity values in water (10-5 cm2 s-124 ). We suggest that gas bubbles escaping from the brine to the atmosphere - as the ice gets more permeable during melt could be responsible for the previously reported high transport coefficients. These results underline that when there is no convective transport within the sea ice, the transport of gas by diffusion through the brines, either in the liquid or gaseous phases, is a major factor in controlling the ocean–atmosphere exchange.

This book provides a cultural and social history of the rise and legitimation of the concept of dynastic continuity in the early history of the Ptolemaic Empire. The scope of the study is therefore neither to provide a general overview of third-century Ptolemaic history, nor to discuss in detail the administrative and economic structures of the Ptolemaic state. Rather, its purpose is to investigate the ways by which the first Ptolemies negotiated and constructed a representation of their power as a dynastic house aspiring to universal dominion, protected by the gods and legitimately continuing the heritage of the Macedonian and Egyptian monarchies. It is argued that they managed to do so by operating within different socio-cultural and ethnic milieus and by pursuing their strategies on a two-fold level: on the one hand, by continuously reshaping the relationship between the present events of the ruling house and its historical and mythical past, so as to adapt it to new political and cultural agendas; on the other hand, by shifting the border between the spheres of human and divine power in order to ensure themselves the legitimacy and loyalty stemming from religious thought and practice. Discussed evidence comprises Greek and Egyptian sources, literary and documentary texts, iconographic and archaeological evidence from the Macedonian conquest of Egypt under Alexander to the ascension of Ptolemy III Euergetes. Whenever possible, a new, encompassing evaluation of old evidence has gained new impetus from the intensive analysis of newly published sources. Secondly, the complex cultural and social factors operating in the construction and legitimation of the Ptolemaic dynasty have been discussed by drawing on the contribution of up-to-date scholarship in cultural and religious history as well as in sociology. The rooting of Ptolemaic power in Egypt and the Eastern Mediterranean is studied as the movement from the immediate but unstable right of conquest established by Alexander, and subsequently claimed by the satrap Ptolemy, to the development of a mature and coherent system of power practices and representations. The structure of the book is meant to provide readers with a chronological and thematic discussion ranging from Alexander’s conquest of Egypt to the first years of Ptolemy III. However, the six chapters that constitute this study can also be read separately as they are conceived as the monographic treatment of major moments or aspects of the cultural, political, and religious history of the early Hellenistic period. Chapter 1 deals with the premises of Ptolemaic power in Egypt by focusing on the time of Alexander’s conquest. The implications of Alexander’s sonship to Zeus Ammon in propaganda and in religion are reviewed by drawing attention to the plurality of audiences (Macedonians, Greeks, Egyptians) for which this motif was conceived and used. Chapter 2 discusses the conflicting patterns of legitimation in the age of the Successors and how Ptolemy exploited them in his rise from satrap to king. Some seminal moments of Ptolemy’s career are re-examined: the acquisition of Alexander’s corpse as a source of embodied legitimacy; the interactions between the leader and pre-existing Macedonian and Egyptian elites as they appear in assembly scenes of Greek historiography and in the hieroglyphic Satrap stele; Ptolemy’s help to the Rhodians against Antigonus and Demetrius and the entanglement between royal charisma and religious honours. Chapter 3 focuses on the figure of Dionysus in Ptolemaic religion and culture from a twofold perspective. Firstly, the chapter provides an innovative analysis of the religious and ideological role of Dionysus in Ptolemy II’s Alexandrian procession described by Callixeinus of Rhodes. Secondly, it aims at offering a contribution for a reappraisal of the figure of Dionysus, of his cults and of the role of his figure within the larger context of the Ptolemaic Empire in the third century BC. Chapter 4 discusses the patterns of divinization of Arsinoe II within the royal couple through the most complete documentary dossier collected thus far on the subject. Rather than constituting the aim of the research, the debate concerning the chronology of Arsinoe’s death and divinization has provided the rough framework for a new investigation of how the image of a solid royal couple was invented and spread in religious life and in propaganda. Diachronic developments in the configurations of the dynastic couple are traced through Greek and Egyptian evidence and discussed in relation to the changing of political agendas during the reign of Ptolemy II. Chapter 5 studies the contribution of Ptolemy III to the construction of Ptolemaic dynastic continuity through old and new evidence, notably by providing fresh observations concerning the recently published decree of Alexandria (243 BC) for the understanding of Ptolemaic royal festivals in general and, more in particular, for the history of the festival Ptolemaia in the second half of the 3rd century BC. Chapter 6 breaks with chronological continuity to trace, through literary and documentary evidence from the Roman period, the development of the tradition envisaging Alexander’s body as a talismanic relic protecting the city of Alexandria. The purpose of this epilogue is to provide a methodological essay of interpretation of cultural traditions in the longue durée, when patterns of continuity developed under the Ptolemies were separated from their original context of diffusion and consequently were re-used to shape the civic identity of Alexandria within the new and broader framework of the Roman Empire. Although focus on the construction of a dynasty as a sequence of legitimate, kindred holders of monarchic power makes Ptolemaic kings and queens the central object of this study, it is argued that sovereigns cannot be considered as the sole holders of the initiative in the political, ideological and religious processes relating to the construction of royal and dynastic imagery. On the contrary, it appears that social agents other than the holders of supreme leadership not only reacted to top-down stimulation, but they also constructed, for their own use, representations of the monarchs that interacted with the message issued by the central power. From this perspective, therefore, dynastic continuity results from the intertextual combination of a variety of ideological and religious motifs stemming from different agents and occasions of communication.

Capgras delusion is characterized by the misidentification of people and by the delusional belief that the misidentified persons have been replaced by impostors, generally perceived as persecutors. Since little is known regarding the neural correlates of Capgras syndrome, the cerebral metabolic pattern of a patient with probable Alzheimer’s disease (AD) and Capgras syndrome was compared with those of 24 healthy elderly subjects and 26 AD patients without delusional syndrome. Compared to the healthy and AD groups, the patient had significant hypometabolism in frontal and posterior midline structures. In light of current neural models of face perception, our patient’s Capgras syndrome may be related to impaired recognition of a familiar face, subserved by the posterior cingulate/precuneus cortex, and impaired reflection about personally relevant knowledge related to a face, subserved by the dorsomedial prefrontal cortex.
