Honeydew is the keystone upon which ants and aphids build their mutualistic relationship. We have investigated how sugar and volatile compounds from honeydew are involved in the discovery, the recognition and the exploitation of aphid colonies by the black garden ant Lasius niger. In addition to semiochemicals produced by aphids, honeydew volatile compounds are used by ant scouts to orient themselves and distantly recognize myrmecophilous species. Once discovered, aphid colonies producing sugars which are the most beneficial to the ants are preferentially tended. In this respect, the ways each sugar acts upon the feeding behavior of ant foragers and triggers the laying of a recruitment trail are essential to understand how their collective exploitation of aphid colonies proceeds and why mutualistic interactions between ants and aphids are maintained. Sensitivity of ant scouts to honeydew sugars was also investigated. Dose-response curves revealed between-sugar differences with foragers being very sensitive even to small amounts of melezitose, a sugar specifically produced by aphid colonies. We discuss about the relevance of honeydew cues used by ants in the selection of sugary resources, the recognition of their honeydew-producing partners as well as in the assessment of size and nutritive value of exploited aphid colonies.

Purpose Chemoradiotherapy has been considered standard treatment for patients with limited-stage aggressive lymphoma on the basis of trials conducted before the introduction of the International Prognostic Index. To evaluate this approach in elderly patients with low-risk localized lymphoma, we conducted a trial comparing chemoradiotherapy with chemotherapy alone. Patients and Methods Previously untreated patients older than 60 years with localized stage I or II histologically aggressive lymphoma and no adverse prognostic factors of the International Prognostic Index were randomly assigned to receive either four cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus involved-field radiotherapy (299 patients) or chemotherapy alone with four cycles of CHOP (277 patients). Results With a median follow-up time of 7 years, event-free and overall survival did not differ between the two treatment groups (P =.6 and P =.5, respectively). The 5-year estimates of event-free survival were 61% for patients receiving chemotherapy alone and 64% for patients receiving CHOP plus radiotherapy; the 5-year estimates of overall survival were 72% and 68%, respectively. In a multivariate analysis, overall survival was affected by stage II disease (P <.001) and male sex (P =.03). Conclusion In this large prospective study, CHOP plus radiotherapy did not provide any advantage over CHOP alone for the treatment of low-risk localized aggressive lymphoma in elderly patients.

Dans le cadre d'une discussion à la croisée de l'architecture et de la philosophie, cette contribution propose de s'attarder à un moment précis de l'histoire récente de l'architecture : la rencontre orchestrée entre Jacques Derrida et Peter Eisenman. Deux hommes auxquels on propose de se rencontrer. Mais surtout, deux disciplines auxquelles on impose de se croiser. Pour revenir sur cet échange aux ambitions interdisciplinaires, nous choisissons de nous concentrer sur un moment précis ; leur Choral Works comme scène (réduite) de cette rencontre ; leur Choral Works en tant que livre, projet et événement médiatique. Mais ils ne faut pas aller très loin dans l'analyse de ce « travail commun » pour que très vite une première difficulté apparaisse : comment parler d'une rencontre des savoirs quand les protagonistes prétendent d'eux-même qu'elle n'a jamais eu lieu ? L'éloquente violence de leur correspondance ne suffit-elle pas pour conclure d'un non-lieu ? Ne s'agit-il pas au final de tout simplement reconnaitre qu'ils ne se sont pas compris ? Peut-être ; mais ce serait si facile. Choisissons plutôt de croire que cette histoire ne peut pas s'en arrêter là. Rejouons la scène. Remettons en jeu leurs attentes et ré-écrivons la fin de leur rencontre manquée. L'objectif est ici de redécouvrir ce qui semblait construire leur intérêt commun, et le mettre à l'épreuve de leurs reproches réciproques. De représenter le décalage entre leur premières admirations et leurs dernières accusations. En marquer l'écart ; le mesurer pour en faire une source de savoir. Pour travailler cet écart, nous planterons le décor depuis l'arrangement de la rencontre ; avec Bernard Tschumi dans le rôle de l'entremetteur et le projet pour le parc de La Villette comme lieu de rendez-vous. Nous nous consacrerons également aux premiers textes de Derrida sur l'architecture (Point de folie – Maintenant l'architecture, Cinquante-deux aphorismes pour un avant-propos) ; au texte du philosophe sur l'architecte américain (Pourquoi Peter Eisenman écrit de si bon livre) ; et à leurs réflexions communes sur khôra et leurs esquisses respectives pour un Choral Works. Bien sur, donner de l'intérêt à une énième relecture de ces textes, même si remis en perpective à partir de leur contexte médiatique, n'est pas un exercice gagné d'avance. Loin de là. Toutefois, si nous acceptons de prendre encore ce risque, c'est qu'il s'agit d'y défendre une intuition : l'intuition qu'il existe aujourd'hui une ré-actualité de la pensée derridienne en architecture. Alors la première étape pour soutenir cette intuition est ici de mesurer l'écart de nos erreurs passées en vue d'ajuster nos attentes en devenir. [less ▲]

A seventeen year-old boy developed left sided chorea in a few days, subsequently involving the four limbs. Although he presented a marfanoid phenotype, genetic analysis of the Fibrillin 1 was normal. The genes for familial chorea and Huntington's disease were also negative. Biological tests showed normal serum homocystein, but revealed very high levels of anti-beta2-GP1 IgG, anticardiolipin and lupus anticoagulant, which remained at similar values for a period of over three months. Electroencephalogram and cerebral magnetic resonance imaging (MRI) showed no abnormalities. Brain PET-scan disclosed bilateral striatal hypermetabolism. The patient was treated with methylprednisolone and low dose of acetylsalicylic acid. He improved markedly after six weeks of treatment, and choreic movements disappeared completely after two months. A control PET-scan performed at this time showed reversion of striated hypermetabolism to a normal pattern. The pathogenic aspects of this relatively rare case of chorea are discussed. [less ▲]

Porcine PAG (pPAG) are placental products of a multigene family that is strongly expressed in the chorionic epithelium (trophoblast and trophectoderm). The objective of this study was to define a pattern of the pPAG proteins, secreted in vitro by chorionic explants harvested on 16-77 days of pregnancy. Trophoblastic and trophectodermal explants were collected from pregnant (PR) gilts (n = 27) and used for protein in vitro production (8-261 h). Endometrial explants of luteal-phase gilts (E10, n = 4) and pseudopregnant gilts (PsE, n = 2) were used as negative controls for protein immunoblotting. Proteins (PR, E10, PsE) were isolated mainly from incubation media, fractionated, dialysed and separated by SDS-PAGE. Heterogeneous Western blotting with various polyclonal anti-PAG sera raised against bovine or ovine antigens (anti-bPAG, or anti-oPAG) initially identified the pPAG proteins. Such blotting of fractionated chorionic proteins allowed for the isolation of porcine antigens that were employed as immunogens to raise several homologous antisera (anti-pPAG). Crude antisera were adsorbed on endometrial extracts or proteins of non-PR pigs, to remove non-relevant antibodies. The patterns of pPAG proteins secreted in Vitro varied throughout pregnancy (35-72 kDa). During implantation, similar to43 kDa (Day 16) or similar to68.1 kDa (Days 17-25) pPAG proteins were detected. During placentation and as pregnancy advanced (Days 31-77), similar to72.3 kDa pPAG proteins were observed. The secretions of parallel multiple smaller proteins (35.4-47.2 kDa), presumably, as forms of processed pPAG precursors, increased with the progress of gestation. In conclusion, the pPAG protein family plays a very important role during implantation, placenta formation and embryonic/foetal development in the pig. [less ▲]

During the periimplantation period, human chorionic gonadotropin (hCG) plays a key role by increasing the uterine blood flow through uterine vessel vasodilatation but also through angiogenesis. Indeed, we previously demonstrated that hCG contributes to endothelial cell recruitment and vessel formation. OBJECTIVE: In this study, hCG was proposed as an arteriogenic factor that could promote perivascular cell recruitment and vessel stabilization. DESIGN: The aortic ring assay, a three-dimensional ex vivo angiogenesis system mimicking all the steps of the angiogenesis process was used to study the impact of hCG on pericyte recruitment and vessel maturation. SETTING: The study was conducted at a university hospital laboratory. MAIN OUTCOME MEASURES: Perivascular cell proliferation, migration, and apposition were quantified by computerized image analysis. RESULTS: Physiological concentrations of hCG (10-400 IU/ml) significantly enhanced pericyte sprouting and migration and gave rise to the maturation and coverage of endothelial capillaries. In a three-dimensional coculture model of endothelial and perivascular cells, hCG enhanced vessel tube formation and endothelial/mural cell adhesion. In addition, hCG stimulated the proliferation of human umbilical vein endothelial cells and smooth muscle cells. The specificity of these effects was determined by using an anti-hCG blocking antibody. Signaling pathways implicated on this hCG effect is protein kinase A and phospholipase C/protein kinase C dependent for the proliferative effect but only phospholipase C/protein kinase C for the migrative process. CONCLUSIONS: Our findings highlight a novel paracrine role of this early embryonic signal in vessel maturation by stimulating perivascular cell recruitment, migration, and proliferation. [less ▲]

Placental PAG mRNA expression and N-glycodiversity of multiple PAG proteins secreted in vitro by trophectoderm (chorion epithelium) of wild pecoran Bovidae taxons was not examined previously. The study on European bison (Eb) aimed: (1) to determine placental PAG mRNA expression by in situ hybridisation; (2) to identify a profile of pecoran PAG protein family secreted in vitro by cotyledonary (CT) explants; (3) to examine N-glycodiversity of the PAG proteins in this wild taxon. In addition, we compared (4) a profile and N-glycodiversity of the PAG protein family secreted in vitro by CT and interCT-trophectoderm (intCT-TRD) explants of domestic ruminants. Cotyledonary sections of the Eb were used for in situ hybridisation (ISH) with S-35-labelled probes produced with porcine PAG cDNA as templates. Various CT and intCT-TRD explants were long-term cultured in vitro. Chorionic proteins were isolated from media, ultra-filtrated ( > 10 kDa MWCO) and analysed by PAGE-Western blotting with various polyclonal anti-PAG sera. Protein samples with or without enzymatic deglycosylation were examined after different times of explant cultures. Released chorionic proteins were deglycosylated by N-glycanase F (PNGase F+) and compared to glycosylated forms (PNGase F-). This is the first paper demonstrating the PAG-like mRNA transcript expression (by ISH) and N-glycodiversity of immuno-reactive PAG-like proteins (produced in vitro by chorionic explants) of European bison. Various PAG proteins of Eb (EbPAG) were secreted by CT explants during long-term in vitro studies. Major similar to 78, similar to 67 and similar to 65 kDa EbPAG-like proteins were reduced by enzymatic deglycosylation (at least by 10 kDa). Considerably smaller amounts of similar to 45 kDa EbPAG-like proteins were also observed. In addition, we have found that various PAG proteins (30-73 kDa) were secreted by bovine CT explants, during long-term in vitro cultures. Corresponding amounts of PAG proteins, similar in M-r, were also secreted by intCT-TRD explants, whose tissues were not utilised for PAG protein extraction during other scientists' previous studies. It seems that the M-r-heterogeneity and N-glycodiversity of the PAG protein family can play very important role during feto-placental interactions in Bovidae species. [less ▲]

This paper is the result of an ethnographic research conducted in the Turkish and Moroccan communities of the Hodimont neighborhood in Verviers. The analysis aims to highlight the matrimonial strategies and the influence of the community into these ones.   A triangular interaction between parents / child / community is at the hart of each wedding’s decision. The modality of this interaction – more or less flexible – seems to be crucial in the determination of the marriage’s form and in the constraining force that can weigh on young people for the choice of their partner. Moreover, every component of young people’s life within the community is influenced by the relations with the parents and the community members. Education, socialization, religious experience, gender perceptions, economic contingencies are dimensions that are crossed by parental and community recommendations. In this context, it can be hard for young people to find a right balance between the fulfillment of the family’s wills and the respect of their own desire. This situation might cause constraints or acts of violence but it might also produce reconciliations and self‐affirmations.   [less ▲]
