We have used the light-cone formulation of the chiral-quark soliton model to investigate the vector and axial content of octet, decuplet, and hypothetical antidecuplet in the flavor $SU(3)$ symmetry limit. We have extended previous works by computing the 7Q contribution to vector and axial charges for the octet and antidecuplet but stayed at the 5Q sector for the decuplet where the full computation needs much more time. As expected, the 7Q component has a weaker impact on the quantities but still changes them by a few percent. We give also a detailed decomposition of those charges into flavor, valence quark, sea quark, and antiquark contributions. Many of them are of course not (yet) measured or estimated and constitute then a theoretical estimation. Among the different interesting observations made in this work are the explicit quadrupole deformation of decuplet baryons due to the pion field and the sum of quark spins larger than the pentaquark one.

The deformation and 40Ar-39Ar dating of recent volcanism that remarkably sits across the North Anatolian Fault eastern termination in Turkey, together with previous studies, put strong constraints on the long- term evolution of the fault. We argue that after a first phase of 10 Ma, characterized by a slip rate of about 3 mm/yr, and during which most of the trace was established, the slip rate jumped to about 20 mm/yr on average over the last 2.5 Ma, without substantial increase of the fault length. The transition correlates with a change in the geometry at the junction with the East Anatolian Fault that makes the extrusion process more efficient. [less ▲]

BACKGROUND: The aim of this study was to evaluate the contribution of bronchial epithelium to airway inflammation, with focus on mRNA and protein expression of cytokines of innate immunity IL-6, IL-10 and TNF-alpha, in horses with Recurrent Airway Obstruction (RAO) during exacerbation and in remission. RESULTS: Despite marked clinical and physiologic alterations between exacerbation and after remission in the RAO horses no differences were detected in either cytokine mRNA or protein levels. Moreover, the expression of investigated cytokines in RAO horses on pasture did not differ from controls.In comparing real-time PCR analysis to results of immunohistochemistry only IL-10 mRNA and protein levels in RAO horses on pasture were significantly correlated (rs = 0.893, p = 0.007). Curiously, in controls examined on pasture the TNF-alpha protein level was positively correlated to IL-10 mRNA expression (rs = 0.967, p = 0.007) and negatively correlated to IL-6 mRNA expression (rs = -0.971, p = 0.001). CONCLUSION: Given the complementary relationship of assessing cytokines directly by immunohistochemistry, or indirectly by PCR to mRNA, the lack of significant changes in either mRNA or protein levels of IL-6, IL-10 or TNF-alpha mRNA in RAO horses in exacerbation suggests that these particular cytokines in bronchial tissue may not play a substantive role in the active inflammation of this disease. To support this contention further studies examining time dependency of expression of IL-6, IL-10 or TNF-alpha are needed, as is expansion of the range of cytokines to include other key regulators of airway inflammation.

By the way of a case study, this paper aims at evaluating the innovative dimension of a training service mediated through Information and Communication Technology (ICT): the so-called e-WOCCQ. The originality of this article is twofold: (1) to question innovation, and (2) to consider the training more commonly as a service, whose major particularity is the implication of the user in the process. The theoretical framework emphasises on the definition of a service and on the concept of added-value. As this experience took place at the very beginning of the project development, an empirical methodology was developed. We assume that the so-called e-WOCCQ is an innovation as it represents an added value for the users. Results show that e-WOCCQ generates costs and benefits of different order, and that the ratio is influenced by factors mostly linked either with the user. Practical (improvements and targeting) and theoretical (modelisation) implications are discussed. [less ▲]

A large number of publications have been devoted to the ultrasonography and hormonal follow-up of the follicular growth. This alteration of the normal follicular growth may concern the recruited, growing or preovulatory follicles mainly during the puberty and post-partum periods. Cyst development results (i) in an endocrine inbalance of the hypothalamo-hypophysial axis: the positive feedback of oestradiol on LH is altered because of a lack in progesterone impregnation of hypothalamic receptors;(ii) in a follicular wall dysfunction. However, data on this mechanism are still lacking; (iii) in animal properties like age, milk production, energetic balance, genetics, post-partum and calving pathologies as endometritis or lameness; (iv) in environnemental factors like nutrition, season, stressfull conditions. This different factors shoud be able to disturbe the hypothalamo-hypophysial complex functions. [less ▲]

Depuis longtemps utilisé pour le suivi sanitaire et la gestion technique des troupeaux laitiers, le résultat du comptage cellulaire de tank et donc indirectement du comptage cellulaire individuel est devenu un critère officiel pour le paiement du lait et le contrôle laitier. L’étude est consacrée à l’évaluation d’un compteur à particules : le Coulter Counter® modèle Z2. Après calibrage primaire et étalonnage de l’appareil, une évaluation de ses performances a été réalisée par la détermination de la justesse, de la fidélité et des critères d’appréciation des analyses sur des échantillons de laits de quartiers. Pour l’appréciation de la justesse, les échantillons de lait ont été dénombrés au préalable par numération microscopique selon la méthode de Prescott et Breed (1910). Les résultats obtenus ont révélé une bonne corrélation (CC = 0,94) avec un coefficient de variation de 3,17 %. La fidélité, évaluée sur la base de la répétabilité (0,2 %) et de la reproductibilité (0,8 %) est de 1 %. Ces valeurs sont nettement inférieures aux normes préconisées par la Fédération Internationale de Laiterie (1995). La valeur diagnostique du matériel utilisé se trouve confirmée par les valeurs de 0,96 et 0,87 % obtenues respectivement pour la sensibilité et la spécificité. La confirmation de la qualité du matériel employé laisse entrevoir son utilisation possible à large échelle dans la Wilaya de Blida. À ce titre il constitue un outil irremplaçable de contrôle de la qualité et de valorisation du lait. [less ▲]

BACKGROUND: During their blood meal, ticks secrete a wide variety of proteins that can interfere with their host's defense mechanisms. Among these proteins, lipocalins play a major role in the modulation of the inflammatory response. METHODOLOGY/PRINCIPAL FINDINGS: We previously identified 14 new lipocalin genes in the tick Ixodes ricinus. One of them codes for a protein that specifically binds leukotriene B4 with a very high affinity (Kd: +/-1 nM), similar to that of the neutrophil transmembrane receptor BLT1. By in silico approaches, we modeled the 3D structure of the protein and the binding of LTB4 into the ligand pocket. This protein, called Ir-LBP, inhibits neutrophil chemotaxis in vitro and delays LTB4-induced apoptosis. Ir-LBP also inhibits the host inflammatory response in vivo by decreasing the number and activation of neutrophils located at the tick bite site. Thus, Ir-LBP participates in the tick's ability to interfere with proper neutrophil function in inflammation. CONCLUSIONS/SIGNIFICANCE: These elements suggest that Ir-LBP is a "scavenger" of LTB4, which, in combination with other factors, such as histamine-binding proteins or proteins inhibiting the classical or alternative complement pathways, permits the tick to properly manage its blood meal. Moreover, with regard to its properties, Ir-LBP could possibly be used as a therapeutic tool for illnesses associated with an increased LTB4 production. [less ▲]

C’est donc un mécanisme qui se suffit à lui-même que nous avons voulu décrire dans ce texte, sans nous préoccuper des suites vécues par les acteurs de nos deux cas d’étude, la production des deux objets qu’ils mobilisent nous apparaissant comme des moments de cristallisation de l’action collective qu’ils esquissent. L’efficacité de ces objets va rester limitée dans le temps et l’espace, ils sont en effet impossibles à utiliser dans d’autres contextes ou par d’autres acteurs. Mais en même temps, ils produisent « quelque chose » que nous avons cherché à expliciter dans les trois séquences de « convention », « représentation » et « transformation ». Ces trois séquences peuvent aussi être retraduites dans les questions suivantes : qu'est-ce qui permet un accord de départ dans un groupe qui n’est pas vraiment constitué et autour d’un problème qui n’est pas défini précisément ? Comment ce problème peut-il être représenté ? Et qu’est que la saisie de cette image provoque ou permet ? La première séquence rend compte d’un arrangement préalable à l’émergence de l’objet. Il traduit l’articulation entre la mobilisation d’une légitimité extérieure au groupe, toujours suspecte, et d’un engagement qui ne fait qu’émerger dans ce groupe. Et ce qui rend possible cette première convention est le format de la scène sur laquelle elle s’exprime, format que choisissent ou acceptent les acteurs. La convention de départ est donc un arrangement de composantes qui apportent des connaissances et un mode de relations utiles à l’action. La seconde séquence est celle de la représentation et du basculement qu’elle rend possible. Les images produites permettent en effet de saisir en un seul coup d’œil les tensions présentes dans le problème qui se découvre. Tenant ensemble individu et collectif, ici et ailleurs, elles opèrent un travail qui lie et délie, concentre et élargit, et qui ouvre la porte à la troisième séquence, qui est de l’ordre de la transformation. Ces images permettent en effet d’explorer, de tester, de questionner, de recomposer, soit autant d’actions qui s’appliquent aux connaissances mobilisées par les acteurs et aux relations qui se créent ou se renforcent. La première et la troisième de ces séquences sont passagères dans des histoires plus longues, mais elles s’inscrivent cependant dans la temporalité des projets que les acteurs cherchent à construire. C’est le temps que nécessite l’exploration des légitimités qui caractérise les connaissances et les relations, légitimités qui s’imposent autant qu’elles s’exposent et qui apportent des occasions d’ouverture et de fermeture. Mais l’efficacité du mécanisme que nous mettons en évidence tient aussi dans la force du basculement qu’il permet et qui s’exprime le mieux dans la deuxième séquence, celle où prédomine la forme et qui est de l’ordre de l’instant : la découverte collective et simultanée d’une image est le moment éphémère de ce mécanisme éphémère. Ainsi, à l’inverse d’une approche qui insisterait sur le caractère structurant des objets, nous soulignons ici leur caractère fugace ou évanescent. Ces intermédiaires ne sont pas des articulations solides, mais des points de basculement dont le degré de réversibilité est variable : ils ne tiennent que par les engagements des acteurs qui les mobilisent et les attachements aux contextes qui les ont produits. Prétextes pour accompagner les explorations et les transformations, ces objets libèrent des ressources nouvelles, qui restent cependant empreintes de toute leur fragilité. En ne disant pas ce qu’il y a à faire, leur force réside avant tout dans leur caractère souple, dans leur capacité à capter l’hétérogène et à le représenter. Or cet hétérogène, nous pouvons le voir à un premier niveau, quand il concerne l’ici et l’ailleurs, ou encore l’individuel et le collectif, soit des changements d’échelles qui constituent un premier enjeu du développement durable. Mais ces objets éphémères nous suggèrent des changements que l’on pourrait qualifier de second ordre, quand ils saisissent simultanément et « en tension » des éléments aussi différents que la quiétude de riverains ou la gestion du patrimoine foncier de propriétaires et un objectif de protection d’un bien commun, ou encore les exigences d’un distributeur à satisfaire au jour le jour son marché national et les préoccupations d’un petit groupe d’éleveurs qui recherchent une conduite « bio » de leur troupeau. Ces objets se situent dans des trajectoires qu’ils ont la capacité d’infléchir, de faire bifurquer, par un travail d’intégration paradoxal qu’ils réalisent en un seul coup d’œil, une force qui produit le basculement dans le changement de relations et de connaissances. Or ces changements nous intéressent puisque nous les voyons au cœur de ces dynamiques d’action collective vers plus de durabilité. Ces objets apparaissent alors comme des appuis stratégiques pour de nouveaux apprentissages collectifs. Et proposant de véritables esquisses de cartes maritimes de mers et d’océans jusqu’alors inconnus, ils apportent, selon nous, des ressources dépassant de loin ce que pouvaient offrir les portulans.

Ovarian cyst treatment and its efficacy imply to make the diagnosis as early as possible during the end of waiting period or period of reproduction of cows potentially concerned. Moreover, we must keep in mind that during the early postpartum period 38 to 80% of cysts spontaneously regress. The choice of a treatment also depends on criteria and sensitivity level of the identified (follicular or luteinized) cyst. Cysts treatment can be curative or preventive. Give an adequate level of nutrition and reduce the frequency of puerperal diseases during the postpartum period can contribute to reduce the risk of ovarian cysts. Curatively, it's possible manually to rupture or to puncture the ovarian cyst by transvaginal way using or not an ultrasonographic control. Such method can be associated with an hormonal therapy. It's also possible to treat the cyst with hormones. Classically, follicular and luteinised cysts are respectively treated by luteotrope hormones (GnRH, hCG) and by PGF2alpha. As the goal of treatment is to assume a new follicular growth, both cysts can be also treated with progestagens given by intravaginal way. During the last years, different hormonal protocols have been used. Ovsynch has been evaluated and compared with others protocols. Until now, such hormonal associations have a rather limited effect on the pregnancy rates. Moreover, they appear rather expensive. [less ▲]

Purpose – Fair trade organisations (FTOs) have been taken quite early as examples of Social Enterprises (SE) and have contributed to the shaping of the SE concept. The purpose of this paper is to examine more deeply the link between FTOs and SE, both at a conceptual and at an empirical level. Design/methodology/approach – First, different theoretical frameworks of SE are introduced and confront FT to each of these frameworks. The second step is an empirical study of FTOs across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTOs. Findings – All the FTOs combine in some way economic, social and sometimes also political goals. FTOs are thus coherent to the “hybrid goals” nature of SEs. FTOs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTOs are closer to the European – participatory – approach while others are closer to US – individual – approaches. Finally, the governance structures of FTOs seem to reflect quite well their goal mix. Research limitations/implications – This paper provides a more solid basis for the often implicit link between FT and SE. Future researches could use this work to explore specific topics of the SE literature in the context of FT (e.g. stakeholders' involvement). The FT example could also be used to examine further the shifting boundaries of the SE reality. Originality/value – The originality of this paper is to apply the SE concept to a specific field and to show how, within this field, there is at the same time a diversity of organisations, reflecting the diversity of SE approaches; and a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations.

In the Kivu region located in east of the Democratic Republic of the Congo, malnutrition and malaria is a major cause of morbidity and mortality. The relationship between malaria and malnutrition is unclear and has never been studied in the Kivu region. This report presents an analysis of data from 5695 children aged 0 to 5 years, admitted to the paediatric ward of Lwiro hospital between November 1992 and February 2004. The weight/age (W/A) index and weight/height (W/H) index expressed with standard deviation in relation to the reference median were calculated (Z score). The association between protein-energetic malnutrition and malaria infection and nutritional indicators was measured based on prevalence ratios determined by univariate analysis and adjusted Odds Ratio (OR) derived using a multivariate model. The prevalence of malaria at the time of admission was 35.8 % (n=5695). The W/A and W/H indexes and serum albumin level were correlated with malaria-related morbidity. Logistic regression showed that high malaria OR was associated with both anthropometric nutritional indicators [WHZ > -2: OR (CI 95 %) 1.7 (1.4-2.2)] [WAZ > -2: OR (CI 95 %) 1.3 (1.1-1.6)] and biological nutritional indicators [serum albumin > or = 23 g/L: OR (CI 95 %) 1.6 (1.2-2.1)]. Our findings indicate that malnourished children at admission have a lower risk of malaria infection. [less ▲]
