A surprisal analysis has been applied to the translational energy distribution (TED) of CH3++F from CH3F giving rise to a new and deeper insight into the dissociation dynamics involved in the process. For both the 16.5 eV and 21.22 eV photon energies used, the direct population at different energy levels of the B2E state of CH3F+ which is radiationlessly coupled to the repulsive CH3F+(A2A1) state, gives rise to wide and negatively surprised total TEDs. At both energies they have to be ascribed to severe limitations in the vibrational excitation of CH3+. Additionally, in the case of 21.22 eV photons, a non-statistical expression has to be used to account for the density of translational states. At both photon energies, the population of the CH3F+ electronic states through autoionization of Rydberg states accounts for (i) the concurrent appearance of TEDs governed by a pure RRKM behavour and (ii) the positively surprised TEDs where the angular momentum conservation plays an important role. At 16.85 eV photon energy the distributions are assigned to CH3F+ (X2E)->CH3+ (X1A'1)+F. At 21.22 eV photon energy, doubly excited electronic states of CH3F+ are assumed to take part and they are correlated with CH3+ (3A")+F channel. [less ▲]

The immune system may be considered as a sensory organ able to respond to different kinds of danger signals that are not detected by nervous cells. The immune response is not autonomous but also regulated by central and peripheral nervous system, as well as by neuropeptides, vitamin D and neuroendocrine axes such as the corticotrope, somatotrope, thyrotrope and gonadotrope axes. During evolution, the thymus emerged concomitantly with recombinase-dependent adaptive immunity as an ‘immune brain’ or a ‘master class’ highly specialized in the orchestration of central immunological self-tolerance. This was an absolute requirement for survival of species because of the high risk of autotoxicity inherent to the stochastic generation of extreme diversity characterizing this novel adaptive type of immune defenses against non-self. The thymus now appears to be an obligatory intersection for the integrated evolution of the major systems of cell-to-cell signaling, the nervous, endocrine and immune systems. The presentation of many self-peptides by thymic major histocompatibility complex (MHC) proteins is controlled by the autoimmune regulator (AIRE) gene/protein and is responsible for the clonal deletion of self-reactive T cells. In the same time, by still unexplained mechanisms, MHC presentation of the same self-peptides in the thymus promotes the generation of self-specific FOXP3+ CD4+CD25+ natural regulatory T cells (nTreg) that are able to inhibit in periphery self-reactive CD4+ and CD8+ T cells having escaped the thymus censorship. Moreover, a thymus dysfunction is more and more established as the primary event driving the development of organ-specific autoimmunity, which is the tribute paid, mainly by mankind, for the preservation of self against non-self. Our novel knowledge about thymus physiology and physiopathology already serves as the basis for the development of various innovative and efficient immunomodulating strategies in pharmacology.

Par rapport à d'autres productions culturelles ou scientifiques, la particularité des médias de masse est qu'ils font quelque chose au peuple en faisant quelque chose du peuple, c'est-à-dire en le représentant à lui-même. La construction mass-médiatique du "peuple" a donc une dimension pragmatique que les études de réception doivent intégrer. C'est à quoi s'attache cette communication, notamment à travers la notion d'adresse, issue du travail de J. Derrida, et celle de "partage du sensible" formalisée par Jacques Rancière. [less ▲]

Le colloque "L'Appel de l'Italie. Les échanges artistiques en France à l'époque moderne. Les Français et les Flamands en Italie", organisé en étroit partenariat par le Département d'Histoire de l'art de l'Université Grenoble 2 et le Musée de Grenoble, a complété et accompagné l'exposition "L'Appel de l'Italie. Français et Nordiques aux XVIIe et XVIIIe siècles dans la Péninsule", qui a fait partie d'une série de manifestations réalisées dans de grands musées français souhaitant montrer un panorama de la création artistique dans les centres politiques italiens à partir des collections publiques françaises. Les textes réunis à l'occasion de cette publication contribuent à faire le point sur les découvertes scientifiques liées au domaine graphique, mais elles soulignent aussi le formidable impact des maîtres italiens et de l'art de la Péninsule sur les artistes du Nord. Les différentes contributions permettent de mettre l'accent sur la dimension européenne des échanges artistiques et culturels et soulignent l'enrichissement mutuel des foyers nationaux. [less ▲]

Epiploic appendagitis is the term used to describe the inflammation of an epiploic appendage. These small masses of fat distributed along the colon, from the caecum to the recto-sigmoid junction can inflammate by torsion, spontaneously or secondarily with the inflammation of an anatomical structure in the neighbourhood. Symptomatology may mimic retro-caecal appendicitis or diverticulitis and the diagnosis by CT avoids unnecessary surgery or hospitalization. Indeed, under conservative treatment by AINS and analgesics, symptomatology regresses in about five days. In this article, we relate the case of a patient with a typical clinical presentation, to remind the elements of this pathological entity. [less ▲]

La compatibilité – ou appétence - entre un système de réparation et le béton support est définie à partir des propriétés du support et de la couche d’apport – essentiellement dans sa phase non liée – ainsi que de l’environnement dans lequel le contact est créé. Elle s’exprime habituellement en termes de variations dimensionnelles, de perméabilité et de propriétés chimiques et électrochimiques. Ces propriétés sont évoquées ou développées pour chacun des matériaux mis en présence : rugosité, porosité, cohésion superficielle et eau interstitielle pour le béton ; retrait, fluage, rigidité, absorption capillaire pour les produits de réparation. Trois conditions fondamentales nécessaires et suffisantes au développement de l’adhérence en tant que signe de la compatibilité entre matériaux sont évoquées et illustrées pour le cas particulier de la préparation de surface : sablage, burinage, hydro démolition, marteau-piqueur, … ont un effet spécifique non seulement sur la rugosité, et donc l’accrochage mécanique du système de réparation, mais aussi sur la cohésion de la couche superficielle du béton [less ▲]

The definition of the adhesion itself presents a duality : on the one hand, adhesion is understood to be a process through which two bodies are brought together and attached (bonded) to each other, in such a manner that external force or thermal motion is required to break the bond. The term "adhesion" (or "sticking") is usually applied in this sense in colloid research on coagulation phenomena. On the other hand, we may examine the process of breaking a bond between bodies that are already in contact; and here, as a quantitative measure of the intensity of adhesion, we can take the force or energy required to separate the two bodies. We studied this problem in the context of repairing mortars laid down on a concrete support; we focused our research on the behaviour of a cementitious slurry applied on two types of concrete support, characterised by their surface preparation (sandblasted and polished surface). We measured and observed the penetration of this slurry into the concrete support. [less ▲]

Central testosterone aromatization is required for the activation of both appetitive (ASB) and consummatory (CSB) male sexual behavior in Japanese quail. There are two major clusters of aromatase immunoreactive (ARO-ir) cells in the rostral forebrain; these outline the nucleus preopticus medialis (POM) and the nucleus striae terminalis (BST). We investigated the role of these nuclei in the regulation of ASB and CSB. Appetitive male sexual behavior was measured with the use of a learned social proximity procedure that quantified the time spent by a male in front of a window with a view of a female who was subsequently released into the cage, providing an opportunity for CSB. Males first acquired the response and then received bilateral electrolytic lesions aimed at the POM or BST, followed by retesting for ASB and CSB. Brain sections were stained for ARO-ir, and lesions to the two ARO-ir cell groups were quantitatively characterized. Lesions damaging the POM completely abolished CSB and also significantly decreased ASB. Lesions of the rostral BST had no effect on ASB, but moderately decreased CSB. Detailed anatomical analysis revealed that lesions of a subdivision of the POM just rostral to the anterior commissure specifically impair CSB, whereas lesions that are more rostral to this subdivision induce a severe deficit in ASB. These data indicate that different subregions of the POM regulate ASB and CSB in a somewhat independent manner, whereas the BST is only important in the regulation of CSB. [less ▲]

Appetitive male sexual behavior was measured in male quail with the use of a learned social proximity procedure that quantified the time spent by a male in front of a window providing a view of a female that was subsequently released into the cage, providing an opportunity for copulation. The learned response is not acquired by castrated males but can be acquired when castrates are treated with testosterone (T) or with the synthetic estrogen diethylstilbestrol or with the endogenous estrogen 17 beta-estradiol. Only birds that become sexually active acquire the response. Conversely, birds in which the consummatory copulatory behavior is disrupted by treatment with the antiestrogen tamoxifen lose the anticipatory response. These results demonstrate that appetitive sexual behavior is, like copulation, activated by T and by estrogens. This suggests that intracerebral aromatization of T also plays a critical role in the activation of this behavior. [less ▲]
