La vérification de programmes consiste à analyser les comportements possibles de programmes en vue de déterminer s’ils seront toujours conformes à ce qui est attendu. Pour ce faire, les caractéristiques souhaitées des comportements sont exprimées formellement et confrontées, par des techniques mathématiques rigoureuses, à l’ensemble des comportements du programme à analyser. Dans ce contexte, les automates jouent un triple rôle. Tout d’abord, ils sont fréquemment utilisés en tant que langage de programmation simplifié pour décrire les programmes à analyser. Ensuite, ils servent de formalisme de description de propriétés de comportements, soit directement, soit par traduction à partir d’un langage logique. Finalement, ils s’avèrent très utiles en tant que formalisme de description d’ensembles infinis de valeurs. [less ▲]

Background. Chronic alcohol abuse is associated with a wide range of cognitive deficits. However, little is known about memory for real-life events (autobiographical memory) in non-amnesic alcoholic patients. The purpose of this study was to investigate (a) non-amnesic alcoholics' ability to recall specific autobiographical memories and (b) their subjective experience when they access specific memories.Method. Twenty non-amnesic (without Korsakoff syndrome) recently detoxified alcoholics and 20 healthy controls completed the Autobiographical Memory Test (AMT), which assesses the frequency of specific (versus general) memories recalled in response to cue words, and the Memory Characteristics Questionnaire (MCQ), which assesses subjective experience (e.g. the amount of sensory and contextual details experienced) when remembering specific events.Results. Alcoholic patients recalled specific memories less frequently and general memories more frequently than healthy controls. Nevertheless, when a specific past event was accessed, alcoholic patients subjectively experienced as many sensory and contextual details as controls.Conclusions. These findings suggest that non-amnesic alcoholics have difficulties strategically accessing event-specific autobiographical knowledge, which might result from changes in frontal lobe function that are associated with alcoholism.

The polled locus has been mapped by genetic linkage analysis to the proximal region of bovine chromosome 1. As an intermediate step in our efforts to identify the polled locus and the underlying causative mutation for the polled phenotype, we have constructed a BAC-based physical map of the interval containing the polled locus. Clones containing genes and markers in the critical interval were isolated from the TAMBT (constructed from Angus and Longhorn genomic DNA) and CHORI-240 (constructed from horned Hereford genomic DNA) BAC libraries and ordered based on fingerprinting and the presence or absence of 80 STS markers. A single contig spanning 2.5 Mb was assembled. Comparison of the physical order of STSs to the corresponding region of human chromosome 21 revealed the same order of genes within the polled critical interval. This contig of overlapping BAC clones from horned and polled breeds is a useful resource for SNP discovery and characterization of positional candidate genes. [less ▲]

The smallness of the observed neutrino masses might have a radiative origin. Here we revisit a specific two-loop model of neutrino mass, independently proposed by Babu and Zee. We point out that current constraints from neutrino data can be used to derive strict lower limits on the branching ratio of flavour changing charged lepton decays, such as μ→eγ. Non-observation of Br(μ→eγ) at the level of 10^(−13) would rule out singly charged scalar masses smaller than 590 GeV (5.04 TeV) in case of normal (inverse) neutrino mass hierarchy. Conversely, decay branching ratios of the non-standard scalars of the model can be fixed by the measured neutrino angles (and mass scale). Thus, if the scalars of the model are light enough to be produced at the LHC or ILC, measuring their decay properties would serve as a direct test of the model as the origin of neutrino masses.

Purpose of the study : The aim of this study was to evaluate the impact of 3D and 2D vision on performance of novice subjects using da Vinci robotic system. Methods : 224 nurses without any surgical experience were divided into two groups and executed a motor task with the robotic system in 2D for one group and with the robotic system in 3D for the other group. Time to perform the task was recorded. Results : Our data showed significant better time performance in 3D view (24.67 +/- 11.2) than in 2D view (40.26 +/- 17.49, P < 0.001). Conclusions : Our findings emphasized the advantage of 3D vision over 2D view in performing surgical task, encouraging the development of efficient and less expensive 3D systems in order to improve the accuracy of surgical gesture, the resident training and the operating time.

The aim of concrete surface preparation prior to repair is to obtain a surface with properties close to that of the bulk concrete. In this paper, the results of an investigation intended to evaluate the mechanical degradation induced by different surface preparation techniques are presented. Optical microscope observations clearly show that more cracking is induced with jack-hammers than with the other investigated techniques and that the cracking density increases with the hammer weight. While more information is needed to evaluate quantitatively the effects of concrete removal operations, it appears from the reported results that techniques such as sandblasting, scarifying and water jetting are preferable, as they clearly leave much less defects in the substrate.

Nowadays, the management of ectopic pregnancy should be codified as often as possible. Two types of treatment are possible. One surgical and the other medical. Our study is concerned with a series of 97 patients hospitalized for suspicion of ectopic pregnancy for whom the risk factors and treatment were analyzed. Our conclusion is that the medical treatment should be more frequently proposed and surgery should prefer the conservative treatment whenever it is still possible. [less ▲]

A study is presented on the crystallization of ornithine acetyltransferase from yeast, which catalyzes the fifth step in microbial arginine synthesis. The use of the counter-diffusion technique removes the disorder present in one dimension in crystals grown by either the batch or hanging-drop techniques. This makes the difference between useless crystals and crystals that allow successful determination of the structure of the protein. The crystals belong to space group P4, with unit-cell parameters a = b = 66.98, c = 427.09 angstrom, and a data set was collected to 2.76 angstrom. [less ▲]

We propose a multi-dimensional strategy, associating immunodetection to a protein fractionating two-dimensional liquid chromatography tool, for serological characterization of microbial antigens. The originality of such immunoproteomic approaches resides in their application in large-scale studies for rapid serotyping of micro-organisms, evaluation of immunomes and could be proposed in the development and monitoring of vaccines.

Successful embryo development requires an extensive endometrial angiogenesis in proximity of implantation site. The glycoprotein hCG is produced even before implantation by trophoblast in normal pregnancy. In this manuscript, we demonstrate an angiogenic effect of hCG in several in vivo (chick chorioallantoic membrane, matrigel plug assay, aortic ring assay) and in vitro experimental models. In contrast, human placental lactogen (hPL) did not display angiogenic properties. LH/hCG receptor was detected in endothelial cells by reverse-transcriptase polymerase chain reaction (RT-PCR) and by Western blotting. In mice aortic ring assay, angiostimulation by hCG was abrogated by deletion of LH/hCG receptor (LuRKO mice). Use of recombinant hCG and anti-hCG antibody (Ab) further confirmed the specificity of this angiogenic activity. By using dibutyryl cAMP, adenylate cyclase, or protein kinase A inhibitors, we demonstrate that hCG-mediated angiogenesis involves adenylyl-cyclase-protein kinase A activation. Addition of hCG to endometrial epithelial epithelial cells, but not to cultured endothelial cells, stimulated vascular endothelial growth factor (VEGF). VEGF and hCG also displayed additive activities. Altogether, these data demonstrate that peritrophoblastic angiostimulation may result from a paracrine dialogue between trophoblast, epithelial, and endothelial cells through hCG and VEGF. [less ▲]

Les changements causés par le vieillissement se déroulent à un rythme différent pour chaque personne et dépendent de facteurs comme le style de vie, les activités et l'environnement ainsi que des facteurs comme le bagage génétique et l'état de santé.La presbyphonie est le terme employé pour définir le vieillissement de la voix. Elle s'observe le plus souvent après 60 ans et touche les deux sexes. Ce trouble vocal est la conséquence d'altérations morphologiques et fonctionnelles des systèmes pneumo-phono-articulatoires qui résultent d'une modification hormonale (thyroïdienne et sexuelles), d'une altération de l'état musculaire, vasculaire, nerveux ou respiratoire, ou encore d'un manque d'exercice vocal.
