Imatinib has drastically changed the outcome of patients with chronic myeloid leukemia (CML), with the majority of them showing a normal life span. Recently, the development of second and third generation tyrosine kinase inhibitors (TKIs) and the possibility of treatment discontinuation made the management of these patients more challenging. In this review, practical management guidelines of CML are presented, adapted to the Belgian situation in 2014. In first line chronic phase patients, imatinib, nilotinib and dasatinib can be prescribed. While second generation TKIs give faster and deeper responses, their impact on long-term survival remain to be determined. The choice of the TKI depends on CML risk score, priority for a deep response to allow a treatment-free remission protocol, age, presence of comorbid conditions, side effect profile, drug interactions, compliance concerns and price. Monitoring the response has to be made according the 2013 ELN criteria, and is based on the bone-marrow cytogenetic response during the first months and on the blood molecular response. Molecular follow-up is sufficient in patients with a complete cytogenetic response. For patients who fail frontline therapy, nilotinib, dasatinib, bosutinib and ponatinib are an option depending of the type of intolerance or resistance. T315I patients are only sensitive to ponatinib, which has to be carefully handled due to cardiovascular toxicity. Advanced phase diseases are more difficult to handle, with treatments including allogeneic stem cell transplantation, which is also an option for patients failing at least two TKIs. The possibility of treatment-free remission and pregnancy are also discussed. [less ▲]

We used three IPCC climate change scenarios (A1B, A2 and B1) in a dynamic vegetation model (CARAIB), to determine the potential future distribution of 75 tree species used by two endemic primate species from the Brazilian Atlantic Forest (BAF). Habitat conservation is a vital part of strategies to protect endangered species, and this is a new approach to understanding how key plant species needed for survival of golden lion tamarins (Leontopithecus rosalia) and golden-headed lion tamarins (L. chrysomelas) might be affected by climate change and what changes to their distribution are likely. The model accurately predicted the current distribution of BAF vegetation types, for 66 % of the individual tree species with 70 % agreement obtained for presence. In the simulation experiments for the future, 72 out of 75 tree species maintained more than 95 % of their original distribution and all species showed a range expansion. At the biome level, we note a substantial decrease in the sub-tropical forest area. There is some fragmentation of the savannah, which is encroached mostly by tropical seasonal forest. Where the current distribution shows a large sub-tropical forest biome, it has been replaced or encroached by tropical rainforest. The results suggested that the trees may benefit from an increase in temperature, if and only if soil water availability is not altered significantly, as was the case with climate simulations that were used. However, these results must be coupled with other information to maximise usefulness to conservation since BAF is already highly fragmented and subject to high anthropic pressure. © 2014 Springer-Verlag Berlin Heidelberg.

Cet article est consacré à la qualification de la maladie de Lyme en France. Principale pathologie vectorielle de l’hémisphère nord, la maladie de Lyme est transmise par une tique du genre Ixodes (Ixodes ricinus en Europe ; Ixodes persulcatus en Asie ; Ixodes scapularis aux États-Unis et au Canada). Les médecins et les malades ont d’abord développé un cadrage infectieux, ancré dans la santé humaine, réservé à Lyme et soumis à une vive controverse. Progressivement, un second cadrage vectoriel s’est structuré autour des entomologistes médicaux puis des écologues, généralement étrangers à la problématique des maladies humaines. Axé sur le vecteur, ce cadrage englobe les autres maladies transmises par Ixodes ricinus en Europe qui, durant les 30 dernières années, n’ont cessé d’être découvertes : bartonnelles, babésioses, tularémie, encéphalite à tiques, etc. Combinée à ces nouvelles pathologies, la notoriété de Lyme a finalement contribué à ouvrir la catégorie « transmission vectorielle » – traditionnellement associée aux moustiques des pays tropicaux – aux tiques et aux maladies de l’hémisphère nord qu’elles véhiculent. Un troisième cadrage axé sur les réservoirs et qualifié de zoonotique commence enfin à se dessiner. Il faut reconnaître dans cette juxtaposition des cadrages – infectieux, vectoriel et zoonotique – une forme d’écologisation des problèmes sanitaires. [less ▲]

This case study analyses how far donors implement aid effectiveness principles at health district level in Mali, and why. It shows that not all aid effectiveness principles are implemented at a similar degree. Most projects have limited impact on health services, but many programmes supported by donors offer positive opportunities for health system strengthening. The representations of different categories of stakeholders diverge – notably, regarding the role of different actors in service provision. A number of consistent strategic logics influence actors’ behaviour. We show that while many donors have committed at global level to respect aid effectiveness principles, implementation lags behind.

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.

Freeplay in aircraft control surface actuators is a common source of nonlinearity that can cause undesirable aeroelastic phenomena and, as a consequence, certification authorities place strict limits on the size of the deadband gaps of actuators. In recent years many authors have worked on determining the effects of freeplay on the dynamic behavior of aeroelastic systems; these efforts have yielded significant improvements in the understanding of the phenomena, but have concentrated on simple models. Investigations of industry-relevant aeroelastic models of complete aircraft with freeplay in the actuators have been much rarer, the main difficulty being the selection of an appropriate modal basis that can represent the full range of possible dynamic phenomena. This work presents a novel implementation of the residual vectors approach to create consistent and numerically stable reduced order models suitable for industrial-standard aeroelastic models of aircraft. The methodology relies on the piecewise linear nature of freeplay to create a single reduction basis that represents the dynamics of the system both inside and outside the freeplay deadband gap. The method is demonstrated on an Embraer generic test bench aircraft, showing that the resulting reduced order model is efficient and effective. Nonlinear analysis is carried out using equivalent linearization as well as time integrations of the full nonlinear system. It is shown that, while equivalent linearization is an indispensable tool for a preliminary mapping of the main aeroelastic instabilities, the time integration-based nonlinear analysis is an essential complementary tool to confirm the characteristics of the system behavior.

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 ▲]

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]

The Jauf Formation miospore succession is synthesized in terms of paleoenvironments and sequence stratigraphy. The data set for this study is obtained from four overlapping, continuously cored, and extensively sampled, boreholes that for a 940 ft composite section. The Jauf Formation ranges in age from late Pragian to latest Emsian. The palynological assemblages, recognized herein, provide the basis for recognizing depositional environments present in the Early Devonian of northern Saudi Arabia. Transgressive – regressive cycles are indicated, not only by lithology but by marked changes in the marine to terrestrially dominated palynological assemblages. Flooding events are recognized by the replacement of spore dominated assemblages by organic-walled microphytoplankton. The maximum flooding interval for the Jauf is reinterpreted based on a correlative event consisting of diverse acritarchs and abundant chitinozoans. [Add details on the paly and sequence stratigraphy here. No.cycles and order.] The new northern Gondwanan biozonation developed by Breuer and Steemans (2012) and used here allows a high-resolution regional biozonation for the Arabian Plate and more intercontinental [?] correlation of the Jauf Formation with other Gondwanan and Euramerican localities. One new spore genus (Zonohilates) and four spore species (Insculptospora maxima, Camarozonotriletes alruwailii, Devonomonoletes crassus and Zonohilates vulneratus) are newly proposed. [less ▲]

Diffusion kurtosis imaging (DKI) is a promising extension of diffusion tensor imaging, giving new insights into the white matter microstructure and providing new biomarkers. Given the rapidly increasing number of studies, DKI has a potential to establish itself as a valuable tool in brain diagnostics. However, to become a routine procedure, DKI still needs to be improved in terms of robustness, reliability, and reproducibility. As it requires acquisitions at higher diffusion31 weightings, results are more affected by noise than in diffusion tensor imaging. The lack of standard procedures for post-processing, especially for noise correction, might become a significant obstacle for the use of DKI in clinical routine limiting its application. We considered two noise correction schemes accounting for the noise properties of multichannel phased-array coils, in order to improve the data quality at signal-to-noise ratio (SNR) typical for DKI. The SNR dependence of estimated DKI metrics such as mean kurtosis (MK), mean diffusivity (MD) and fractional anisotropy (FA) is investigated for these noise correction approaches in Monte Carlo simulations and in in vivo human studies. The intra-subject reproducibility is investigated in a single subject study by varying the SNR level and SNR spatial distribution. Then the impact of the noise correction on inter-subject variability is evaluated in a homogeneous sample of 25 healthy volunteers. Results show a strong impact of noise correction on the MK estimate, while the estimation of FA and MD was affected to a lesser extent. Both intra- and inter-subject SNR related variability of the MK estimate is considerably reduced after correction for the noise bias, providing more accurate and reproducible measures. In this work, we have proposed a straightforward method that improves accuracy of DKI metrics. This should contribute to standardization of DKI applications in clinical studies and making valuable inferences in group analysis and longitudinal studies. [less ▲]

Over the past two decades, major advances have been made in the number and range of agents available for the treatment of osteoporosis, all with proven anti-fracture efficacy. Unfortunately, compliance with these treatments is not optimal, and a number of patients could be considered as non-responders. Consequently, monitoring anti-osteoporotic therapy could be part of successful osteoporosis management. Currently, no formal well-accepted clinical practice guidelines are available for monitoring anti-osteoporosis therapies. Changes in bone mineral density and bone turnover markers, while on therapy, have potential value in monitoring treatment but their assessment and, consequently, their benefits could be limited by metrological and clinical issues. Moreover, their effectiveness is probably drug dependant. Recommendation for the standardisation of the methodology when analysing the potential relevance of tools for the monitoring of osteoporosis therapy is needed. [less ▲]

We conducted a questionnaire survey of the 565 European Society for Blood and Marrow Transplantation centers to analyze the outcome of allogeneic hematopoietic stem cell transplantation (alloSCT) in recipients of solid organ transplantation (SOT). We investigated 28 patients with malignant (N=22) or nonmalignant diseases (N=6), who underwent 31 alloSCT procedures: 12 after kidney, 13 after liver, and three after heart transplantation. The incidence of solid organ graft failure at 60 months after first alloSCT was 33% (95% confidence interval [CI], 16–51%) for all patients, 15% (95% CI, 2–40%) for liver recipients, and 50% (95% CI, 19–75%) for kidney recipients (p = 0.06). The relapse rate after alloSCT (22%) was low following transplantation for malignant disorders, despite advanced stages of malignancy. Overall survival at 60 months after first alloSCT was 40% (95% CI, 19–60%) for all patients, 51% (95% CI, 16–86%) for liver recipients, and 42% (95% CI, 14–70%) for kidney recipients (p = 0.39). In summary, we show that selected SOT recipients suffering from hematologic disorders may benefit from alloSCT and experience enhanced long-term survival without loss of organ function. [less ▲]

The influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin - BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10 to 30 µm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC). The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The interpretation of XPS data allowed the complexity due to the ubiquitous presence of organic contaminants to be coped with, and the surface composition to be expressed in terms of both the amount of adlayer and the mass concentration of adlayer constituents. When soiled with a suspension of particles in water, glass was much less cleanable than polystyrene, which was attributed to its much lower water contact angle, in agreement with previous observations on starch soil. Dextran was easily desorbed and did not affect the cleanability. The presence of BSA at the interface strongly improved the cleanability of glass while the contact angle did not change appreciably. In contrast, soiling polystyrene with quartz particles suspended in a BSA solution instead of water did not change markedly the cleanability, while the contact angle was much lower and the aggregates of soiling particles were more flat. These observations are explained by the major role of capillary forces developed upon drying, which influence the closeness of the contact between the soiling particles and the substrate and, thereby, the adherence of particles. The capillary forces are proportional to the liquid surface tension and depend in a more complex way on contact angles of the particles and of the substrate. The dependence of cleanability on capillary forces, and in particular on the liquid surface tension, is predominant as compared with its dependence on the size and shape of the soiling aggregates, which influence the efficiency of shear forces exerted by the flowing water upon cleaning.

In the context of the reduction of greenhouse gas emissions caused by deforestation and forest degradation (the REDD+ program), optical very high resolution (VHR) satellite images provide an opportunity to characterize forest canopy structure and to quantify aboveground biomass (AGB) at less expense than methods based on airborne remote sensing data. Among the methods for processing these VHR images, Fourier textural ordination (FOTO) presents a good potential to detect forest canopy structural heterogeneity and therefore to predict AGB variations. Notably, the method does not saturate at intermediate AGB values as do pixelwise processing of available space borne optical and radar signals. However, a regional scale application requires to overcome two difficulties: (i) instrumental effects due to variations in sun-scene-sensor geometry or sensor-specific responses that preclude the use of wide arrays of images acquired under heterogeneous conditions and (ii) forest structural diversity including monodominant or open canopy forests, which are of particular importance in Central Africa. In this study, we demonstrate the feasibility of a rigorous regional study of canopy texture by harmonizing FOTO indices of images acquired from two different sensors (Geoeye-1 and QuickBird-2) and different sun-scene-sensor geometries and by calibrating a piecewise biomass inversion model using 26 inventory plots (1 ha) sampled across very heterogeneous forest types. A good agreement was found between observed and predicted AGB (RSE=15%; R²=0.85; p-value<0.001) across a wide range of AGB levels from 26 Mg/ha to 460 Mg/ha, and was confirmed by cross validation. A high-resolution biomass map (100 m pixels) was produced for a 400 km² area, and predictions obtained from both imagery sources were consistent with each other (r=0.86; slope=1.03; intercept=12.01 Mg/ha). These results highlight the horizontal structure of forest canopy as a powerful descriptor of the entire forest stand structure and heterogeneity. In particular, we show that quantitative metrics resulting from such textural analysis offer new opportunities to characterize the spatial and temporal variation of the structure of dense forests and may complement the toolbox used by tropical forest ecologists, managers or REDD+ national monitoring, reporting and verification bodies.

Depuis les travaux de Jean-Louis FOURNEL et Jean-Claude ZANCARINI, notamment, il est établi que les auteurs florentins qui vécurent à l’époque des guerres d’Italie identifièrent immédiatement la nouveauté et le caractère extraordinaire des faits qui bouleversèrent leur époque. Parmi ceux-ci, le célèbre Nicolas Machiavel mais aussi son ami et contemporain, Francesco Guicciardini, qui, si l’histoire littéraire ne lui a pas toujours fait la part belle, retrouve ces dernières années la place qui lui revient dans celle des idées. Auteur, historiographe mais aussi lieutenant des troupes pontificales lors de la Ligue de Cognac et, donc, acteur de l’histoire en train de se jouer, Francesco Guicciardini est en prise directe avec les événements ; dans sa volumineuse correspondance se mêlent petite et grande Histoire. Or, si le substantif et l’adjectif « contemporaneo » existent en italien depuis Dante au moins, Guicciardini n’en fait l’usage ni dans ses œuvres, ni dans ses lettres qui ne comptent aucune occurrence du terme. Partant de ce constat, je me propose, dans mon article, de relever et d’analyser le langage utilisé par Guicciardini pour nommer le moment auquel il vit, en cerner les contours et la façon dont celui-ci se distingue de ce qui précède pour former un moment à part : les expressions qui disent le présent (tempo presente/tempi presenti, questi tempi, medesimi tempi) et celles qui le caractérisent (conditione de' tempi, extraordinario, tempi strani) ou qui expriment le moyen de l’affronter (remedii conformi a’ tempi) seront, dès lors, au centre de mon attention.

In this paper, we argue that an expanded conception of the distinction between speaker-oriented and subject-oriented inferences is crucial for understanding the motivations and mechanisms of semantic change in grammaticalization and subjectivation, on the one hand, and for clarifying the links between semantic change and reductive formal changes. Speaker-oriented inferences have significant consequences, leading to the relaxation of selectional restrictions on a construction. In turn, the relaxation of selectional restrictions can create conditions in which the type- and token-frequency of a construction can rise considerably. Furthermore, changes in the selectional restrictions on a construction can themselves catalyze semantic change by coercing listeners into new form-function pairings. This framework is applied to the grammaticalization of allative futures, a typological comparative concept developed in order to compare structurally diverse future tenses. A small typological study allows us to reconsider some problematic pathways of grammaticalization and to suggest some alternative analyses. Following the typological discussion, a detailed diachronic case study of a verbless allative future in Ancient Egyptian is presented. [less ▲]

This consensus article reviews the diagnosis and treatment of osteoporosis in geriatric populations. Specifically, it reviews the risk assessment and intervention thresholds, the impact of nutritional deficiencies, fall prevention strategies, pharmacological treatments and their safety considerations, the risks of sub-optimal treatment adherence and strategies for its improvement. INTRODUCTION: This consensus article reviews the therapeutic strategies and management options for the treatment of osteoporosis of the oldest old. This vulnerable segment (persons over 80 years of age) stands to gain substantially from effective anti-osteoporosis treatment, but the under-prescription of these treatments is frequent. METHODS: This report is the result of an ESCEO (European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis) expert working group, which explores some of the reasons for this and presents the arguments to counter these beliefs. The risk assessment of older individuals is briefly reviewed along with the differences between some intervention guidelines. The current evidence on the impact of nutritional deficiencies (i.e. calcium, protein and vitamin D) is presented, as are strategies to prevent falls. One possible reason for the under-prescription of pharmacological treatments for osteoporosis in the oldest old is the perception that anti-fracture efficacy requires long-term treatment. However, a review of the data shows convincing anti-fracture efficacy already by 12 months. RESULTS: The safety profiles of these pharmacological agents are generally satisfactory in this patient segment provided a few precautions are followed. CONCLUSION: These patients should be considered for particular consultation/follow-up procedures in the effort to convince on the benefits of treatment and to allay fears of adverse drug reactions, since poor adherence is a major problem for the success of a strategy for osteoporosis and limits cost-effectiveness.

Virus-like particles (VLPs) of human papillomavirus (HPV) are used as a vaccine against HPV-induced cancer, and recently we have shown that these VLPs are able to activate natural killer (NK) cells. Since NK cells collaborate with dendritic cells (DCs) to induce an immune response against viral infections and tumors, we studied the impact of this crosstalk in the context of HPV vaccination. NK cells in the presence of HPV-VLPs enhanced DC maturation as shown by an upregulation of CD86 and HLA-DR and an increased production of IL-12p70, but not of the immunosuppressive cytokine IL-10. This activation was bi-directional. Indeed, in the presence of HPV-VLPs, DCs further activated NK cells by inducing the upregulation of cell surface activation markers (CD69 and HLA-DR). The function of NK cells was also improved as shown by an increase in IFN-gamma secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent.

Les ouvrages de Frédéric Lordon ont offert ces dernières années un éclairage nouveau des mécanismes de la finance et du capitalisme en régime néolibéral, en vertu de la place centrale qu’ils accordent aux affects. Il est frappant que cette entreprise – qui est triple: analyse de la finance, analyse du capitalisme, analyse de la domination – soit doublée d’une attention portée au discours même qui la développe. On peut repérer une telle attention dans la pluralité des genres de discours qu’investit Frédéric Lordon : ouvrages « savants » ou « universitaires », mais aussi courts essais engagés aux éditions Raisons d’agir, articles de presse dans Le Monde Diplomatique notamment, tenue du blog « La pompe à phynance » sur le site du même journal, et même pièce de théâtre récemment adaptée au cinéma, D’un retournement l’autre. Comédie sérieuse sur la crise financière. En quatre actes, et en alexandrins . Diversité de genre entre les différents types de textes, donc. Diversité interne à chacun de ces textes, aussi : le lecteur de Frédéric Lordon se trouve toujours à cheval sur plusieurs codes rhétoriques dont joue l’auteur dans un même ouvrage. On pourrait bien sûr tenir cette double diversité pour la simple conséquence du talent d’écriture de Lordon, ou d’un plaisir pris par l’auteur à jouer du langage et des ethos qu’il construit. Le présent article propose au contraire de considérer cette diversité comme le résultat d’un véritable travail sur les modalités rhétoriques du discours critique sur le capitalisme financiarisé, qu’il faut articuler aux principaux postulats de sa théorie sociale. L’hypothèse défendue sera, précisément, de considérer qu’il y a une construction rhétorique qui participe de l’entreprise critique et, du même coup, qui s’inscrit comme un geste politique dans une « société des affects ».

Les gammapathies monoclonales de signification indéterminée (GMSI) sont fréquentes dans la population générale. Leur potentiel évolutif malin impose une surveillance clinique régulière et prolongée. Cependant, les GMSI forment un groupe très hétérogène et tous les patients n’ont pas le même risque de transformation maligne. Plusieurs critères biologiques simples, disponibles en routine ont été identifiés comme facteurs prédictifs de la transformation. Les scores prédictifs de transformation maligne combinant plusieurs de ces facteurs permettront probablement la classification des patients en fonction de leur risque évolutif. La prise en charge pourra ainsi être adaptée au risque individuel de chaque patient [less ▲]

« Savourer la nourriture et respirer la culture marocaine deviennent une expérience et une émotion unique, à découvrir et à vivre grâce à la combinaison d’arômes, goûts, couleurs, formes et musiques ». Au travers de ce slogan, un renommé restaurant d’inspiration marocaine de la ville de Milan en Italie, invitait ses clients à voyager au travers de leur sensorialité dans une culture alimentaire (et par synecdoque, une culture tout court) autre. Le goût les aurait amenés à expérimenter un exotisme, qui était néanmoins contrôlé, car certaines conditions imposées par les normes locales faisaient en sorte que le déplacement vécu ne fût pas excessivement déstabilisant. Le résultat de ces négociations consistait d’un menu qui accostait les gastronomies marocaine et italienne (ou les procédures de l’une et de l’autre) dans certains plats décrits comme « fusion », qui satisfaisaient (ou non) les exigences des clients. Dans cet article, je vise à mettre en évidence les mécanismes de production discursive et matérielle de ces plats, ainsi comme les opinions des consommateurs. Pour ce faire, j’analyserai le matériel ethnographique collecté auprès du local en question en le comparant avec les pratiques observés dans d’autres restaurants milanais. En ce qui concerne les effets obtenus, j’appuierait mon analyse sur une plateforme de médias sociaux consacrée aux recensions d’endroits et locaux touristiques.

Jatropha curcas oil has an insecticidal activity harnessed by the farmers in Niger. In this study, we compared the insecticidal activity of two batches of oil conserved during 70 days, one exposed to light and the other kept in the dark. The insecticidal efficacy was evaluated in a field with three concentrations (5, 10 and 15%) trial on the main pests of Cowpea (Vigna unguiculata (L.) Walp) and in a laboratory test on Megalurothrips sjostedti Trybon (Thysanoptera: Thripidae) with different concentrations of crude oil (50; 100; 150 and 200 µl). No difference in insecticidal effect was found between the two modes of oil conservation, both in the laboratory and in the field. In the field, regardless of the mode of conservation, the concentrations of 10% of J. curcas oil enables a reduction of over than 80% of thrips, aphids, and bugs compared to the control. Its increased seeds yield more than 50%. The concentration of 15% gives an insecticidal effect comparable to that of the reference treatment (deltaméthrine) but induces phytotoxicity symptoms on the leaves of Cowpea. [less ▲]

We numerically investigate the one-dimensional transport of Bose-Einstein condensates in the context of guided atom lasers using a mean-field description of the condensate in terms of a spatially discretized Gross-Pitaevskii equation. We specifically consider a waveguide configuration in which spatial inhomogeneities and nonvanishing atom-atom interactions are restricted to a spatially localized scattering region of finite extent. We show how the method of smooth exterior complex scaling can be implemented for this particular onfiguration in order to efficiently absorb the outgoing flux within the waveguide. A numerical comparison with the introduction of a complex absorbing potential as well as with the analytically exact elimination of the dynamics of the free non-interacting motion outside the scattering region, giving rise to transparent boundary conditions, clearly confirms the accuracy and efficiency of the smooth exterior complex scaling method.

In 1994, during the International Conference on Population and Development convened by the United Nations in Cairo, a shocking video was shown, realized by an operator of CNN and depicting the circumcision of a ten-year-old child living in this very same city. Discourses around female circumcision were not new in Egypt and in the international community, but what was considered as a new episode of a recurrent scandal (not the last one indeed) led to enhance the "war against bad government"[1]. A war fought by means of ideological weapons produced by expert knowledges among which the medical and the feminist ones. The assignment of a value to the state of integrity of the female body and to the women freedom of choice, both designed according to Western canons, led to different actions to “save” Egyptian women. In this context, development agencies fosters a widespread representation of the victim, constituted by the woman mutilated body. Such representation is functional to put in place programs which do not guarantee a freedom of choice, but rather require adherence to another female model, one that defines the "modern" woman. My article, based on ethnographic experience, aims at highlighting the complexity of such dynamics and the role played by humanitarianism within them. Female body becomes the arena where local and international economic powers operate, disregarding a real understanding of the practice, its meanings and its eventual change. ________________________________________ [1] Foucault, Michel.

During the past 2 decades, many interventions were proven effective in the management of postmenopausal osteoporosis. The objective of an anti-osteoporosis treatment is to reduce fracture rates, ideally at all skeletal sites (i.e. spine, hip, and other non-spine). The armamentarium against osteoporosis includes anti-resorptive agents (i.e. bisphosphonates, selective estrogen receptor modulators and denosumab), bone-forming agents (i.e. peptides from the parathyroid hormone family) and one agent with a dual mechanism of action (i.e. strontium ranelate). All these medications combine anti-fracture efficacy with a reasonable benefit/risk profile. However, the choice of a particular chemical entity, in one individual patient is based on the knowledge and expertise of the physician. Prioritization of drugs should be based on the individual profile of the patient, the severity of osteoporosis and the specific contraindications, warnings and precautions of use of the various available medications.

Burkitt lymphoma (BL) is a rare but very aggressive non-Hodgkin’s lymphoma characterized by an isolated translocation t(8;14)(q24;q32). The sporadic form is the subentity most frequently encountered in our country. Diagnosis and initial work-up must be completed rapidly to start treatment as soon as possible. Positron emission tomography (PET) scan is useful for initial staging and to evaluate the chemosensitivity of the tumor during and after treatment. After debulking, it is recommended to add rituximab to chemotherapy. Currently intensive short-cycle chemotherapies (ISCC) and low intensity chemotherapies (LIC) are two valuable options. Radiotherapy is not indicated except in case of central nervous system involvement. Patients achieving complete remission must be followed carefully during the first year to detect recurrence of the disease. More than 80% of patients sustain their remission one year following initial treatment and are considered cured. For patients in partial remission or with chemosensitive relapse, autologous stem cell transplantation is recommended following re-induction with non-cross-resistant polychemotherapy. Monitoring complete blood counts and cognitive functions is important to detect late toxicity of the applied therapies. [less ▲]

This study aimed to develop sex reversal procedures targeting the embryonic period as tools to study the early steps of sex differentiation in Nile tilapia with XX, XY and YY sexual genotypes. XX eggs were exposed to masculinizing treatments with androgens (17α-methyltestosterone, 11-ketotestosterone) or aromatase inhibitor (Fadrozole), whereas XY and YY eggs were subjected to feminizing treatments with estrogen analog (17α-ethynylestradiol). All treatments consisted of a single or double 4-h immersion applied between 1 and 36 h post-fertilization (hpf). Concentrations of active substances were 1000 or 2000 µg l-1 in XX and XY, and 2000 or 6500 µg l-1 in YY. Masculinizing treatments of XX embryos achieved a maximal sex reversal rate of 10 % with an exposure at 24 hpf to 1000 µg l-1 of 11-ketotestosterone or to 2000 µg l-1 of Fadrozole. Feminization of XY embryos was more efficient and induced up to 91 % sex reversal with an exposure to 2000 µg l-1 of 17α-ethynylestradiol. Interestingly, similar treatments failed to reverse YY fish to females, suggesting either that a sex determinant linked to the Y chromosome prevents the female pathway when present in two copies, or that a gene present on the X chromosome is needed for the development of a female phenotype.

This paper proposes a novel approach to detect differential item functioning (DIF) among dichotomously scored items. Unlike standard DIF methods that perform an item-by-item analysis, we propose the “LR lasso DIF method”: logistic regression (LR) model is formulated for all item responses. The model contains item specific intercepts, an effect of the sum score and item-group interaction (i.e. DIF) effects, with a lasso penalty on all DIF parameters. Optimal penalty parameter selection is investigated through several known information criteria (AIC, BIC and cross-validation) as well as through a newly developed alternative. A simulation study was conducted to compare the global performance of the suggested “LR lasso DIF” method to the logistic regression and Mantel-Haenszel methods (in terms of false alarm and hit rates). It is concluded that for small samples the LR lasso DIF approach globally outperforms the logistic regression method, and also the Mantel-Haenszel method, especially in the presence of item impact, while it yields similar results with larger samples.

Depression is one of the most important mental health problems and a leading cause of disability. Selective serotonin reuptake inhibitors (SSRIs) are considered as first-line therapy for the treatment of depressive symptoms among older adults because of their presumed favorable adverse effect profile. However, they could have deleterious effects on the bone. Evidence from longitudinal, crosssectional, and prospective cohort studies suggests that the use of antidepressants at therapeutic doses is associated with decreased bone mineral density and increased fracture risk. The association between SSRIs use and fracture risk could potentially differ depending on dose, exposure duration, time of exposure, age, or sex. However, the risk of fracture declined rapidly after discontinuation of use of SSRIs. The evidence now seems sufficient to consider adding SSRIs to the list of medications that contribute to osteoporosis. In practice, assessment of risk factor for osteoporosis or fractures could be made taking into account age, gender, duration, and severity of depression, length of SSRI treatments, and other concurrent risk factors.

Organometallic-mediated radical polymerization (OMRP) has seen a significant growth in the last years notably due to the development of new metal complexes, especially cobalt derivatives. Despite of this, none of the reported complexes offers optimal control for monomers with very different reactivity, which somewhat limits the synthesis of copolymers. In order to expand the scope of cobalt-mediated radical polymerization (CMRP), we investigated an in situ ligand exchange reaction for modulating the properties of the cobalt complex at the polymer chain-end and adjusting the C-Co bond strength involved in the control process. With the aim of improving the synthesis of poly(vinyl acetate)-b-poly(n-butyl acrylate) copolymers, bidentate acetylacetonate ligands, which impart high level of control to the polymerization of vinyl acetate (VAc), were replaced in situ at the PVAc-cobalt chain-end by tetradentate Salen type ligands that are more suited to acrylates.

Perception results from a combination of actual data and interpretative schemata based on pre-existing knowledge. Thus, ensuing subjective experience depends on the dynamic interplay between data-driven and conceptually-driven processing. A chronic imbalance between these two sources of stimulus encoding is likely to be maladaptive and could underlie cognitive and behavioral disturbances similar to that observed in schizotypy, especially if the balance is tipped too far towards conceptually-driven processing (i.e., Internal encoding style). This study aimed to examine the relationships between encoding style and various dimensions of schizotypy, by using a questionnaire that evaluates the extent to which pre-existing schemata (versus cues from the outside world) affect encoding processes. Consistent with previous findings, our results revealed that both Cognitive-Perceptual and Disorganization dimensions were related to an internal mode of encoding, suggesting that individuals with these features may be characterized by a disposition to biases at early stages of encoding.

A systematic study on the presence of bottlenose dolphins (Tursiops truncatus) in the Río Negro Estuary (RNE), Patagonia Argentina, was carried out between the months March – July from 2008 to 2011. Data on the dolphin’s activity patterns were gathered via an Ad Libitum focal group sampling mode accompanying dorsal fin images taken for identification and re-identification of individuals. A total effort of 188 h resulted in 58 h of positive observation of 124 dolphin groups (sightings per unit effort (SPUE) = 0.66 groups/h). Data analysis showed two main activity states for the observed groups, travelling (65%) and foraging (26%). The remaining 9% of the groups were involved in other activity states. The photo-identification effort, which started opportunistically in 2006, resulted in a catalogue of 21 individual dolphins, with a total mean re-identification rate of 9 days (max = 24 days). When comparing these pictures to the existing catalogue of Bahía San Antonio (approximately 200 km west from the study area) dorsal fins of 20 individuals could be positively matched and most (n = 17) could be subsequently re-identified in both areas, indicating their long distance movements along the North Patagonian coast during the austral autumn months. This season coincides with the lowest amount of feeding activity observed in Bahía San Antonio. This study suggests that bottlenose dolphins enter RNE, mainly during autumn, to forage. It appears that the search for food resources may be the trigger for their movement patterns along the North Patagonian coast during this season, at least for certain individuals. More research is needed to accurately confirm this hypothesis. [less ▲]

Analogical mapping is a domain-general cognitive process found in language development, and more particularly in the abstraction of construction schemas. Analogical mapping is considered as the general cognitive process which consists in the alignment of two or several sequences in order to detect their common relational structure and generalize it to new items. The current study investigated analogical mapping across modalities in children with specific language impairment (SLI). Nineteen children with SLI and their age-matched peers were administered two tasks: a linguistic analogical reasoning task (composed of syllables) and a similar non-linguistic analogical reasoning task (composed of pictures). In the two tasks, the items presented were divided into two groups: items with perceptual cues and items without perceptual cues. Children had to complete a sequence sharing the same relational structure as previously presented sequences. Results showed an expected group effect with poorer performance for children with SLI compared to children with typical language development (TLD). Results corroborate hypotheses suggesting that children with SLI have difficulties with analogical mapping, which may hinder the abstraction of construction schemas. Interestingly, whereas no interaction effect between group and modality (linguistic vs. non-linguistic) was revealed, a triple interaction Group*Modality*Perceptual support was observed. In the non-linguistic task, the performance of children with SLI was the same for items with and without perceptual clues, but in the linguistic task they performed more poorly for items without perceptual cues compared to items with perceptual cues. The results and limits of the study are discussed. [less ▲]

Perfectly Matched Layers (PMLs) are widely used for the numerical simulation of wave-like problems defined on large or infinite spatial domains. However, for both the time-dependent and the time-harmonic cases, their performance critically depends on the so-called absorption function. This paper deals with the choice of this function when classical numerical methods are used (based on finite differences, finite volumes, continuous finite elements and discontinuous finite elements). After reviewing the properties of the PMLs at the continuous level, we analyse how they are altered by the different spatial discretizations. In the light of these results, different shapes of absorption function are optimized and compared by means of both one- and two-dimensional representative time-dependent cases. This study highlights the advantages of the so-called shifted hyperbolic function, which is efficient in all cases and does not require the tuning of a free parameter, by contrast with the widely used polynomial functions.

The pre-eminence of the realistic conception has long locked the field of study of the power in International Relations, which is nowadays highly questioned. The analysis of some “new powers” emergence is as such a tremendous learning experience. In order to go beyond the classical antagonism between the institutional perspectives (cooperation) and the realistic ones (rivalry), this paper deals with the power in an alternative way, from a heterodox approach of hegemony, which allows us to make out the phenomena of insidious and not felt so domination. Following the example of China, committed to building a status of world power, sustained by a self-legitimizing discourse abounding with Third-World overtones (anti-hegemonism, multipolarization of the world, South-South cooperation, etc.), the increase in its global influence does not only depend on the availability of its – tangible and intangible – resources, nor on its ability to mobilize them adequately (smart power). China also values the image that it has of itself (self-perception), the image that it tends to convey on the international stage (representation), as well as the perception of its status by the other actors of the international system (external recognition). The power of China is measured through its capacity to “assert itself as a reference” for its emerging peers, or even for Western powers. [less ▲]

The aphid–ant mutualistic relationships are not necessarily obligate for neither partners but evidence is that such interactions provide them strong advantages in terms of global fitness. While it is largely assumed that ants actively search for their mutualistic partners namely using volatile cues; whether winged aphids (i.e. aphids’ most mobile form) are able to select ant-frequented areas had not been investigated so far. Ant-frequented sites would indeed offer several advantages for these aphids including a lower predation pressure through ant presence and enhanced chances of establishing mutuaslistic interactions with neighbour ant colonies. In the field, aphid colonies are often observed in higher densities around ant nests, which is probably linked to a better survival ensured by ants’ services. Nevertheless, this could also result from a preferential establishment of winged aphids in ant-frequented areas. We tested this last hypothesis through different ethological assays and show that the facultative myrmecophilous black bean aphid, Aphis fabae L., does not orientate its search for a host plant preferentially towards ant-frequented plants. However our results suggest that ants reduce the number of winged aphids leaving the newly colonized plant. Thus, ants involved in facultative myrmecophilous interactions with aphids appear to contribute to structure aphid populations in the field by ensuring a better establishment and survival of newly established colonies rather than by inducing a deliberate plant selection by aphid partners based on the proximity of ant colonies.

Mismatched unrelated donor (MMUD) or umbilical cord blood (UCB) can be chosen as alternative donors for allogeneic stem cell transplantation but might be associated with long lasting immune deficiency. Sixty-six patients who underwent a first transplantation from either UCB or 9/10 MMUD (n= 36) and who survived beyond 3 months were evaluated. Immune reconstitution was prospectively assessed at sequential time points after transplantation. NK, B, CD4+ and CD8+T cells and their subsets as well as regulatory T cells (Treg) were studied. Detailed analyses on infections occurring after 3 months were also assessed. The 18-month cumulative incidences of infection-related death were 8 and 3%, and of infections were 72 and 57% after MMUD and UCB transplantation, respectively. Rates of infection per 12 patient-month were roughly 2 overall (1 for bacterial, 0.9 for viral and 0.3 for fungal infections). Memory, naïve CD4+ and CD8+T cells, naïve B cells and Treg cells reconstitution between the 2 sources was roughly similar. Absolute CD4+T cells hardly reached 500 per μL by one year posttransplantation and most B cells were of naïve phenotype. Correlations between immune reconstitution and infection were then performed by multivariate analyses. Low CD4+ and high CD8+T cells absolute counts at 3 months were linked to increased risks of overall and viral (but not bacterial) infections. When assessing for the naïve/memory phenotypes at 3 months among the CD4+ T cell compartment, higher percentages of memory subsets were protective against late infections: central memory CD4+T cells protected against overall and bacterial infections; late effector memory CD4+T cells protected against overall, bacterial and viral infections. At the opposite, high percentage of effector- and late effector-memory subsets at 3 months among the CD8+ T cell compartment predicted higher risks for viral infections. Patients transplanted from alternative donors represent a population with very high risk of infection. Detailed phenotypic analysis of immune reconstitution may help to evaluate infection risk and to adjust infection prophylaxis. [less ▲]

Ni–Cu/SiO2 xerogel catalysts have been synthesized by cogelation of industrial tetraethoxysilane (Dynasil) and chelates of Ni and Cu with industrial 3-(2-aminoethylamino)propyltrimethoxysilane (Dynasylan DAMO) in industrial ethanol denatured with diethyl phthalate. Despite the use of industrial grade reagents, highly dispersed bimetallic Ni–Cu/SiO2 xerogel catalysts were obtained. These samples are composed of completely accessible Ni–Cu alloy crystallites with sizes of 1.6–3.4 nm located inside silica particles exhibiting a monodisperse microporous distribution. It appears that the bimetallic complex acts as a nucleation agent in the formation of silica particles. The combination of results obtained from the calculation of the metal ratio in catalysts, H2 chemisorption and transmission electron microscopy allowed calculating the surface composition of the nickel–copper particles in Ni–Cu/SiO2 cogelled xerogel catalysts. Values obtained indicate a very pronounced surface enrichment with copper. While 1,2-dichloroethane hydrodechlorination over pure nickel mainly produces ethane, increasing copper content in bimetallic catalysts results in an increase in ethylene selectivity. The specific consumption rate of 1,2-dichloroethane decreases when copper loading increases. The turnover frequency, that is, the number of catalytic cycle per active site (nickel atom and its surrounding copper atoms) and per second, seems to be independent of surface composition of alloy particles.

Despite H. scabra’s wide distribution and status as one of the best candidates for sustaining the development of tropical sea cucumber aquaculture, very few data are available regarding the organic fraction it assimilates in practice. In this study we report experimental results where H. scabra’s diet was supplemented with various 15N-labelled organic fractions of sediment. We used juveniles weighing between 38- 88 mg at the beginning of the experiment (ca. 2 cm long and 30 days old). Their growth was measured over a four week period and their 15N composition recorded. The results showed that H. scabra juveniles assimilated all added organic components from both dissolved and particulate fractions of the sediment. Bacteria seem to be an important food source for juveniles, even more so than microphytobenthos (diatoms). [less ▲]

BACKGROUND: General recommendations for a reference case for economic studies in rheumatic diseases were published in 2002 in an initiative to improve the comparability of cost-effectiveness studies in the field. Since then, economic evaluations in osteoarthritis (OA) continue to show considerable heterogeneity in methodological approach. OBJECTIVES: To develop a reference case specific for economic studies in OA, including the standard optimal care, with which to judge new pharmacologic and non-pharmacologic interventions. METHODS: Four subgroups of an ESCEO expert working group on economic assessments (13 experts representing diverse aspects of clinical research and/or economic evaluations) were charged with producing lists of recommendations that would potentially improve the comparability of economic analyses in OA: outcome measures, comparators, costs and methodology. These proposals were discussed and refined during a face-to-face meeting in 2013. They are presented here in the format of the recommendations of the recently published Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement, so that an initiative on economic analysis methodology might be consolidated with an initiative on reporting standards. RESULTS: Overall, three distinct reference cases are proposed, one for each hand, knee and hip OA; with diagnostic variations in the first two, giving rise to different treatment options: interphalangeal or thumb-based disease for hand OA and the presence or absence of joint malalignment for knee OA. A set of management strategies is proposed, which should be further evaluated to help establish a consensus on the "standard optimal care" in each proposed reference case. The recommendations on outcome measures, cost itemisation and methodological approaches are also provided. CONCLUSIONS: The ESCEO group proposes a set of disease-specific recommendations on the conduct and reporting of economic evaluations in OA that could help the standardisation and comparability of studies that evaluate therapeutic strategies of OA in terms of costs and effectiveness.

This study investigates the meteorological variation in revealed preference travel data. The main objective of this study is to investigate the impact of weather conditions on daily activity participation (trip motives) and daily modal choices in the Netherlands. To this end, data from the Dutch National Travel Household Survey of 2008 were matched to hourly weather data provided by the Royal Dutch Meteorological Institute and were complemented with thermal indices to indicate the level of thermal comfort and additional variables to indicate the seasonality of the weather conditions. Two multinomial logit–generalised estimation equations (MNL-GEE) models were constructed, one to assess the impact of weather conditions on trip motives and one to assess the effect of weather conditions on modal choice. The modelling results indicate that, depending on the travel attribute of concern, other factors might play a role. Nonetheless, the thermal component, as well as the aesthetical component and the physical component of weather play a significant role. Moreover, the parameter estimates indicate significant differences in the impact of weather conditions when different time scales are considered (e.g. daily versus hourly based). The fact that snow does not play any role at all was unexpected. This finding can be explained by the relatively low occurrence of this weather type in the study area. It is important to consider the effects of weather in travel demand modelling frameworks because this will help to achieve higher accuracy and more realistic traffic forecasts. These will in turn allow policy makers to make better long-term and short-term decisions to achieve various political goals, such as progress towards a sustainable transportation system. Further research in this respect should emphasise the role of weather conditions and activityscheduling attributes. [less ▲]

We conducted a prospective randomized trial to assess hemoglobin (Hb) response to recombinant human erythropoietin (rhEPO) therapy after hematopoietic cell transplantation (HCT). Patients (n=131) were randomized (1:1) between no treatment (control arm) or erythropoietin (Neorecormon®) at 500 U/kg/week (EPO arm). Patients were also stratified in 3 cohorts: patients undergoing myeloablative HCT with rhEPO to start on day 28, patients given nonmyeloablative HCT (NMHCT) with rhEPO to start on day 28, and patients also given NMHCT but with rhEPO to start on day 0. The proportion of complete correctors (i.e. achieving Hb ≥ 13 g/dL) before day 126 post-transplant (primary endpoint) was 8.1% in the control arm (median not reached) and 63.1% in the EPO arm (median time 90 days) (p<0.001). Hb levels were higher and transfusions requirements decreased (p<0.001) in the EPO arm, but not during the first month in the nonmyeloablative cohort starting rhEPO on day 0. There was no difference in rates of thrombo-embolic events or other complications between the 2 arms. This is the first randomized trial to demonstrate that rhEPO therapy hastens erythroid recovery and decreases transfusion requirements when started one month after allogeneic HCT. There was no benefit to start rhEPO earlier after NMHCT. [less ▲]

Herpesviruses have mainly co-evolved with their hosts for millions of years. However, bovine herpesvirus 1 (BoHV1) and related ruminant alphaherpesviruses have been reported to cross the species barrier. Bubaline herpesvirus 1 (BuHV1) is an alphaherpesvirus closely related to BoHV1 and BoHV5. According to the serological cross-relationships between ruminant alphaherpesviruses, several surveys have studied the occurrence of BoHV1-related virus infection in wild and domestic ruminant species. Recent studies in Argentina showed an increase in serological prevalence against BoHV1 related viruses in water buffaloes (Bubalus bubalis) population. The aim of this study was to investigate the presence of related ruminant alphaherpesvirus in the Argentinean water buffalo population. BuHV1 was successfully isolated from 5 out of 225 buffaloes analyzed. One isolate was obtained from nasal secretions, and the others were from vaginal swabs. The buffaloes belonged to four different farms located in northeastern Argentina. The isolates were characterized as alphaherpesvirus by direct immunofluorescence using FITC-anti-BoHV1 IgG. Restriction analysis performed with BamHI and BstEII on the complete genome showed differences between the isolates and those from BoHV1 and BoHV5 subtypes. Phylogenetic analysis on both UL27 and US6 showed similarity in tree topology. While three of the isolates grouped together with sequences of BoHV5, two other isolates clustered separately. Genetic analysis of eight concatenated sequences from all isolates and references strains showed high nucleotide sequence identity between BuHV1 and BoHV5. While three of the isolates clustered together with the BoHV5 reference strain, the last two isolates were closely related to an Australian BuHV1 strain. To our knowledge, this is the first report on the isolation and molecular characterization of BuHV1 in South America. Phylogenetic analysis suggested that two different BuHV1 lineages circulate in the Argentinean water buffalo population. [less ▲]

Despite the proven predictive ability of bone mineral density, Fracture Risk Assessment Tool (FRAX(R)), bone turnover markers, and fracture for osteoporotic fracture, their use as targets for treatment of osteoporosis is limited. INTRODUCTION: Treat-to-target is a strategy applied in several fields of medicine and has recently become an area of interest in the management of osteoporosis. Its role in this setting remains controversial. This article was prepared following a European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) working group meeting convened under the auspices of the International Osteoporosis Foundation (IOF) to discuss the feasibility of applying such a strategy in osteoporosis in Europe. METHODS: Potential targets range from the absence of an incident fracture to fixed levels of bone mineral density (BMD), a desired FRAX(R) score, a specified level of bone turnover markers or indeed changes in any one or a combination of these parameters. RESULTS: Despite the proven predictive ability of all of these variables for fracture (particularly BMD and FRAX), their use as targets remains limited due to low sensitivity, the influence of confounders and current lack of evidence that targets can be consistently reached. CONCLUSION: ESCEO considers that it is not currently feasible to apply a treat-to-target strategy in osteoporosis, though it did identify a need to continue to improve the targeting of treatment to those at higher risk (target-to-treat strategy) and a number of issues for the research agenda. These include international consensus on intervention thresholds and definition of treatment failure, further exploration of the relationship between fracture and BMD, and FRAX and treatment efficacy and investigation of the potential of short-term targets to improve adherence.

Saccharomyces cerevisiae C8-5 and Candida tropicalis F0-5 isolated from traditional sorghum beer were tested for kinetic parameters on barley malt extract, YPD (863 medium) and for alcohol production. The results showed that C. tropicalis has the highest maximum growth rate and the lowest doubling time. Values were 0.22 h-1 and 0.32 h-1 for maximum growth rate, 3 h 09 min and 2 h 09 min for doubling time respectively on barley malt extract and YPD. On contrary, glucose consumption was the fastest with S. cerevisiae (-0.36 g/l/h and -0.722 g/l/h respectively on barley malt extract and YPD). When these two yeasts were used as starters in pure culture and co-culture at proportion of 1:1 and 2:1 (cell/cell) for barley malt extract fermentation, we noticed that maltose content increased first from 12.12 g/l to 13.62-16.46 g/l and then decreased. The highest increase was obtained with starter C. tropicalis + S. cerevisiae 2:1. On contrary, glucose content decreased throughout all the fermentation process. For all the starters used, the major part of the ethanol was produced at 16 h of fermentation. Values obtained in the final beers were 11.4, 11.6, 10.4 and 10.9 g/l for fermentation conducted with S. cerevisiae, C. tropicalis, C. tropicalis + S. cerevisiae 1:1 and C. tropicalis + S. cerevisiae 2:1. Cell viability measurement during the fermentation by using flow cytometry revealed that the lowest mean channel fluorescence for FL3 (yeast rate of death) was obtained with C. tropicalis + S. cerevisiae 2:1 after 48 h of fermentation.

The Banzhaf power and interaction indexes for a pseudo-Boolean function (or a cooperative game) appear naturally as leading coefficients in the stan- dard least squares approximation of the function by a pseudo-Boolean func- tion of a specified degree. We first observe that this property still holds if we consider approximations by pseudo-Boolean functions depending only on specified variables. We then show that the Banzhaf influence index can also be obtained from the latter approximation problem. Considering cer- tain weighted versions of this approximation problem, we introduce a class of weighted Banzhaf influence indexes, analyze their most important properties, and point out similarities between the weighted Banzhaf influence index and the corresponding weighted Banzhaf interaction index. We also discuss the issue of reconstructing a pseudo-Boolean function from prescribed influences and point out very different behaviors in the weighted and non-weighted cases. [less ▲]

The dominant shoulder of two populations of men and women composed of 11 subjects each were evaluated in three dimensions for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematics and range of motion were studied separately. For flexion and abduction and with regard to the scapular kinematic, external rotation were significantly larger for women than men. The differences were of at least 5° at 120° of humeral elevation. Upward rotations were identical. Women also showed larger average active humero-thoracic range of motion. The mean differences were of 13°, 7°, 12° and 5° for abduction, flexion, internal rotation and external rotation, respectively. No difference was observed between the scapular resting positions of both populations. The observed differences concerning both the scapular and humeral patterns would indicate that the shoulder behavior of men and women should not be expected to be similar. [less ▲]

Thiamine triphosphate (ThTP) was discovered over 60 years ago and it was long thought to be a specifically neuroactive compound. Its presence in most cell types, from bacteria to mammals, would suggest a more general role but this remains undefined. In contrast to thiamine diphosphate (ThDP), ThTP is not a coenzyme. In E. coli cells, ThTP is transiently produced in response to amino acid starvation, while in mammalian cells, it is constitutively produced at a low rate. Though it was long thought that ThTP was synthesized by a ThDP:ATP phosphotransferase, more recent studies indicate that it can be synthesized by two different enzymes: (1) adenylate kinase 1 in the cytosol and (2) FoF1-ATP synthase in brain mitochondria. Both mechanisms are conserved from bacteria to mammals. Thus ThTP synthesis does not seem to require a specific enzyme. In contrast, its hydrolysis is catalyzed, at least in mammalian tissues, by a very specific cytosolic thiamine triphosphatase (ThTPase), controlling the steady-state cellular concentration of ThTP. In some tissues where adenylate kinase activity is high and ThTPase is absent, ThTP accumulates, reaching ≥ 70% of total thiamine, with no obvious physiological consequences. In some animal tissues, ThTP was able to phosphorylate proteins, and activate a high-conductance anion channel in vitro. These observations raise the possibility that ThTP is part of a still uncharacterized cellular signaling pathway. On the other hand, its synthesis by a chemiosmotic mechanism in mitochondria and respiring bacteria might suggest a role in cellular energetics. [less ▲]

By screening 104 faecal samples from asymptomatic calves in Italy, bovine norovirus RNA was detected with a prevalence rate of 10.5 % (11/104). A continuous sequence spanning the RdRp region and the 50 end of the capsid gene was generated for 7 of the 11 strains. Upon phylogenetic analysis, five strains were grouped with GIII.2 Newbury2-like viruses, and one strain was grouped with GIII.1 Jena-like noroviruses. Interestingly, one strain (80TE/IT) was genetically related to the GIII.1/Jena/80/De in the RdRp but resembled the GIII.2/Newbury2/76/UK in the capsid gene, suggesting a recombination event occurring in the ORF1/ORF2 junction region.

In this study, we applied feminization treatments of 4 h on XY (17α-ethynylestradiol 2000 µg l-1) and YY (6500 µg l-1) Nile tilapia embryos on the first dpf. The mechanism of early sex reversal was investigated by searching for changes in the expression profiles of some sex-differentiating genes in the brain (cyp19a1b, foxl2 and amh) and in sexual steroids (testosterone, 17β-estradiol and 11-ketotestosterone) concentrations during embryogenesis and gonad differentiation. No sex reversal was observed in YY but sex reversal rates in XY progenies ranged from 0 to 60 %. These results, together with the clearance profile of 17α-ethynylestradiol confirmed the existence of an early sensitive period for sex determination encompassing embryonic and larval development, prior to any sign of gonad differentiation. The estrogen treatment induced an increased expression of cyp19a1b and a higher level of testosterone and 17β-estradiol at 4 dpf in XY and YY. Foxl2 and amh were repressed at 4 dpf and expression levels were not different between treated and control groups at 14 dpf suggesting that foxl2 did not control cyp19a1b in the brain of tilapia embryos. Increased cyp19a1b expression in treated embryos could reflect a sign of early brain sexualization but alone cannot account for the sex reversal effect as the treatment was ineffective in YY. The differential sensitivity of XY and YY genotypes to embryo induced-feminization suggests that a sex determinant on the sex chromosomes, either a Y repressor or an X activator may influence the sex reversal during the first steps of tilapia embryogenesis.

Understanding heat and mass transfers in porous materials is crucial in many areas of scientific research. Mathematical models have constantly evolved, their differences lying mainly in the choice of the driving potentials used to describe moisture flows, as well as in the complexity of characterizing the physical phenomena involved. Models developed in the field of Building Physics (HAM models) are used to describe the behavior of envelope parts and assess their impact on user comfort and energy performance. The water balance equation can be described in many ways; it is a function of the boundary conditions considered and the fact they induce high or low water content in the porous materials used. This paper gives an overview of various formulations for this equation that are found in the Building Physics literature. It focuses first on the physically based formulation of moisture balance, drawing on the Representative Elementary Volume (REV) concept, coupled with thermodynamic flow rates description. This is then reformulated in line with various main moisture state variables offering a wide variety of expressions that are compared with available models. This approach provides access to all secondary transport coefficients associated with the process of mathematical transformation. Particular emphasis is placed on the moisture storage function choice and its impact on the final mathematical formulations. [less ▲]

Hyperbranched and star shaped polymers have raised tremendous interests because of their unusual structural and photochemical properties which provide them potent applications in various domains, namely in the biomedical field. In this context, the development of adequate tools aiming to probe particular three-dimensional features of such polymers is of crucial importance. In this present work, ion mobility coupled with mass spectrometry was used to experimentally derive structural information related to cationized linear and star-shaped poly-ε-caprolactones as a function of their charge state and chain length. Two major conformations were observed and identified using theoretical modeling: (1) near spherical conformations whose size is invariant with the polymer topology for long and lightly charged chains and (2) elongated conformations whose size varies with the polymer topology for short and highly charged chains. These conformations were further confirmed by collisional activation experiments based on the ejection thresholds of the coordinated cations that vary according to the elongation amplitude of the polymer chains. Finally, a comparison between solution and gas-phase conformations highlights a compaction of the structure with a loss of specific chain arrangements during the ionization and desolvation steps of the electrospray process, fueling the long-time debated question related to the preservation of the analyte structure during the transfer into the mass spectrometer.

In the last three decades, the development of the artisanal and small-scale mining (ASM) sector has been increasing in the Democratic Republic of Congo (DRC), bringing more and more urban families into this flourishing business sector, and among them, children. At first glance, one could see children in the mining sector mainly as victims entangled in the flows of raw materials of unbridled capitalism. But this paper aims to look at the often unconceivable, and as a result neglected, social agency of children even when they are involved in stigmatized and prohibited types of child labour. To do so, it relies on the results of a socio-anthropological collective research project on children’s mining activities which was carried out in a small locality called La Ruashi in the city of Lubumbashi (Province of Katanga). The article aims to provide a more comprehensive understanding of what is often normatively only labelled as ‘child labour’ by looking at different spheres of social relations within which children are embedded. Examining the set of social interactions that children have with their families, the broader community and their ‘peers’, several ‘family portraits’ are offered, highlighting a heterogeneity of social interpretations regarding this ‘new’ form of child work. It will be shown that for families from middle-class background, this kind of work is often socially disruptive, at the forefront of inter-generational conflict. As for families from lower classes, social changes induced by children’s mining activities are often better incorporated into the family habitus. Common social changes encountered in all families irrespective of class belonging will also be portrayed, showing the transversal societal impact these ‘new’ forms of child economic activities can provoke at a micro level.

This paper offers a critical discussion of the so-called argument from the transparency of experience. We recall of the argument against the historical background of phenomenal anti-dualism (Natorp, Wundt, Russell) and identify three difficulties of it. Eventually, we propose an alternative view, which we call phenomenological dualism. On the proposed view, there is a sense in which our mental states may be said to appear to us, hence there is a sense to say that there are mental phenomena. [less ▲]

Context. GJ 436b is one of the few transiting warm Neptunes for which a detailed characterisation of the atmosphere is possible, whereas its non-negligible orbital eccentricity calls for further investigation. Independent analyses of several individual datasets obtained with Spitzer have led to contradicting results attributed to the different techniques used to treat the instrumental effects. Aims. We aim at investigating these previous controversial results and developing our knowledge of the system based on the full Spitzer photometry dataset combined with new Doppler measurements obtained with the HARPS spectrograph. We also want to search for additional planets. Methods. We optimise aperture photometry techniques and the photometric deconvolution algorithm DECPHOT to improve the data reduction of the Spitzer photometry spanning wavelengths from 3-24 {\mu}m. Adding the high precision HARPS radial velocity data, we undertake a Bayesian global analysis of the system considering both instrumental and stellar effects on the flux variation. Results. We present a refined radius estimate of RP=4.10 +/- 0.16 R_Earth, mass MP=25.4 +/- 2.1 M_Earth and eccentricity e= 0.162 +/- 0.004 for GJ 436b. Our measured transit depths remain constant in time and wavelength, in disagreement with the results of previous studies. In addition, we find that the post-occultation flare-like structure at 3.6 {\mu}m that led to divergent results on the occultation depth measurement is spurious. We obtain occultation depths at 3.6, 5.8, and 8.0 {\mu}m that are shallower than in previous works, in particular at 3.6 {\mu}m. However, these depths still appear consistent with a metal-rich atmosphere depleted in methane and enhanced in CO/CO2, although perhaps less than previously thought. We find no evidence for a potential planetary companion, stellar activity, nor for a stellar spin-orbit misalignment. [ABRIDGED] [less ▲]

This paper draws on vulnerability analysis as it emerged as a complement to classical risk analysis, and it aims at exploring its ability of nurturing risk and vulnerability governance actions. An analysis of the literature on vulnerability analysis allows us to formulate a threefold critique: first, vulnerability analysis has been treated separately in the natural and the technological hazards fields. This separation prevents vulnerability to unleash the full range of its potential, as it constraints appraisals into artificial categories and thus already closes down the outcomes of the analysis. Second, vulnerability analysis focused on assessment tools that are mainly quantitative, whereas qualitative appraisal is a key to assessing vulnerability in a comprehensive way and to informing policy-making. Third, a systematic literature review of case studies reporting on participatory approaches to vulnerability analysis allows us to argue that participation has been important to address the above, but it remains too closed down in its approach and would benefit from embracing a more open, encompassing perspective. Therefore, we suggest rethinking vulnerability analysis as one part of a dynamic process between opening-up and closing-down strategies, in order to support a vulnerability governance framework.

Cet article expose le développement d’une méthodologie automatique pour la détection des changements du bâti en vue d'une mise à jour semi automatique des cartes urbaines. L'approche est basée sur la comparaison entre une carte existante et une image à très haute résolution spatiale (THRS) récente. Elle s'enchaine sur 4 étapes. D'abord l'image est segmentée pour produire des primitives. Ces dernières sont caractérisées par 4 catégories d'attributs. Des classifieurs avancés par apprentissage supervisé (CAAS) ont été utilisés dans l'étape de la classification. Le paramétrage optimal de ces classifieurs est obtenu automatiquement par validation croisée en se référant au meilleur taux d'erreur. La prédiction finale des objets est déduite par un combineur de multiples classifieurs (CMC) conçu à partir des 3 meilleurs CAAS. Enfin, une étape de détection des changements permet d'identifier les primitives qui représentent les changements du bâti. Les données utilisées concernent la ville de Rabat (Maroc). Une image QuickBird a été utilisée avec un plan existant à l'échelle 1:10,000. Indépendamment de la qualité de la forme des bâtiments détectés, la méthode offre des meilleurs taux en exhaustivité (91.7%) et en exactitude (81.5%). [less ▲]

Objective: The objective of this paper is to propose, starting from the description of a clinical emblematic case, a theoretical synthesis of the work of phenomenological psychopathology dedicated to melancholia and typus melancholicus (TM), a clinical concept that describes the premorbid personality vulnerable to major depression (“melancholia” for the psychopathological tradition). Method: This is phenomenological analysis of a case study of melancolia, of its premorbid personality and pathogenic triggering situation. We adopt two main phenomenological keys to understanding the develpment of melancholia : role-identity theory and desynchronization theory. The former understands melancholia as a disorder of identity triggered by the loss of the social role with which one has previously over-identifed. The latter sees melancholia as the effect of the desynchronisation from the social environment that further develops into an inhibition of the conative–affective dynamics of life. We present the case of Jonas (64 years old), whose mother (94 years old) recently died. Before his mother’s death, Jonas’ life was entirely orchestrated by the caring for his mother and synchronized in time with this (e.g., he used to go to her house every 4 hours, took all his meals with her, etc.). Jonas, in addition to being hyper-synchronized and hyper-syntonic, fulfills all diagnostic criteria for TM, including “orderliness”, “conscientiousness”, “hyper/heteronomia” and “intolerance of ambiguity”. TM’s attach a disproportioned importance to their social roles (or external representations of identity) at the expense of their own ego-identity. Results: The passage from pre-morbid personality to melancholia is triggered by the death of Jonas’ mother that entails a profound depersonalization. Desynchronization and role loss cause Jonas fall into this severe depersonalization, whose core feature is the feeling of the loss of feeling. Conclusions: This original contribution demonstrates a clinical case can contribute to the construction and refinement of theoretical and conceptual frameworks (like princeps Tellenbach's studies). Over-synchronized tempo and over-identification with social role are emblematically in this case the two sides of the same coin. A parallelism can be established between synchronization (with the mother) and respect for the role at the expense of own identity. The clinical case of Jonas highlights a conceptual bridge between the model of melancholia as loss of social role and the model of melancholia as desynchronization. [less ▲]

The ocean’s continental margins face strong and rapid change, forced by a combination of direct human activity, anthropogenic CO2-induced climate change, and natural variability. Stimulated by discussions in Goa, India at the IMBER IMBIZO III, we (1) provide an overview of the drivers of biogeochemical variation and change on margins, (2) compare temporal trends in hydrographic and biogeochemical data across different margins (3) review ecosystem responses to these changes, (4) highlight the importance of margin time series for detecting and attributing change and (5) examine societal responses to changing margin biogeochemistry and ecosystems. We synthesize information over a wide range of margin settings in order to identify the commonalities and distinctions among continental margin ecosystems. Key drivers of biogeochemical variation include long-term climate cycles, CO2-induced warming, acidification, and deoxygenation, as well as sea level rise, eutrophication, hydrologic and water cycle alteration, changing land use, fishing, and species invasion. Ecosystem responses are complex and impact major margin services including primary production, fisheries production, nutrient cycling, shoreline protection, chemical buffering, and biodiversity. Despite regional differences, the societal consequences of these changes are unarguably large and mandate coherent actions to reduce, mitigate and adapt to multiple stressors on continental margins.

Objectives: Our objective is to achieve a phenomenological cross-study of melancholic and manic crises. To do this, we analyze the relationship between these two psychopathological states by means of the concepts of "narrative identity" and "intentionality". Method: From clinical cases and with reference to various theoretical models derived from phenomenological psychopathology, we discuss similarities and differences between mania and melancholia. Results: Narrative identity is based on a double movement: that of the enunciation of a speech focused on his history and that of an act of creation. From different clinical situations, we find that: (1) the melancholic retains the ability to elaborate a narrative about his history but the creative dimension of this narrative is absent, and (2) conversely, the manic experiences only the creative dimension. Discussion: Intentionality, as the tendency of consciousness to move toward something beyond itself, proves to be the center of the manic existence without being able to set itself within the boundaries of factual constraints. The melancholic, conversely, experiences an existence in which consciousness has lost its capacity to aim beyond itself. Conclusions: Melancholia and mania are quite specific forms of being-in-world with particular identity and temporal experiences. These two states share a fundamental psychopathological feature, that we named here “manque chiasmatique”: they are disorders of the intentional movement that constitutes narrative identity, that is, of the dialectics between the rootedness (“enracinenment”) of self in its past and the possibility of creation of a new identity.
