Dans son film de montage Le fond de l’air est rouge, Chris Marker compile un ensemble de représentations hétérogènes issues d’une décennie de luttes (ouvrières, étudiantes, indépendantistes, etc.) dans le monde. Par l’assemblage de ces images, le cinéaste déploie une historiographie a priori mélancolique et défaitiste. Le présent texte entend dépasser cette interprétation unilatérale de la critique politique des images pour y identifier les traces d’un retour chronique à l’espoir militant. [less ▲]

A complete census of planetary systems around a volume-limited sample of solar-type stars (FGK dwarfs) in the Solar neighborhood (d ≤ 15 pc) with uniform sensitivity down to Earth-mass planets within their Habitable Zones out to several AUs would be a major milestone in extrasolar planets astrophysics. This fundamental goal can be achieved with a mission concept such as NEAT—the Nearby Earth Astrometric Telescope. NEAT is designed to carry out space-borne extremely-high-precision astrometric measurements at the 0.05 μas (1 σ) accuracy level, sufficient to detect dynamical effects due to orbiting planets of mass even lower than Earth's around the nearest stars. Such a survey mission would provide the actual planetary masses and the full orbital geometry for all the components of the detected planetary systems down to the Earth-mass limit. The NEAT performance limits can be achieved by carrying out differential astrometry between the targets and a set of suitable reference stars in the field. The NEAT instrument design consists of an off-axis parabola single-mirror telescope (D = 1 m), a detector with a large field of view located 40 m away from the telescope and made of 8 small movable CCDs located around a fixed central CCD, and an interferometric calibration system monitoring dynamical Young's fringes originating from metrology fibers located at the primary mirror. The mission profile is driven by the fact that the two main modules of the payload, the telescope and the focal plane, must be located 40 m away leading to the choice of a formation flying option as the reference mission, and of a deployable boom option as an alternative choice. The proposed mission architecture relies on the use of two satellites, of about 700 kg each, operating at L2 for 5 years, flying in formation and offering a capability of more than 20,000 reconfigurations. The two satellites will be launched in a stacked configuration using a Soyuz ST launch vehicle. The NEAT primary science program will encompass an astrometric survey of our 200 closest F-, G- and K-type stellar neighbors, with an average of 50 visits each distributed over the nominal mission duration. The main survey operation will use approximately 70% of the mission lifetime. The remaining 30% of NEAT observing time might be allocated, for example, to improve the characterization of the architecture of selected planetary systems around nearby targets of specific interest (low-mass stars, young stars, etc.) discovered by Gaia, ground-based high-precision radial-velocity surveys, and other programs. With its exquisite, surgical astrometric precision, NEAT holds the promise to provide the first thorough census for Earth-mass planets around stars in the immediate vicinity of our Sun. [less ▲]

Introduction : Le plasma riche en plaquettes (PRP) aurait des effets bénéfiques sur les symptômes des tendinopathies grâce à la libération locale de leurs nombreux facteurs de croissance. Le but de cette étude est d’évaluer les résultats d’une injection de PRP sur la symptomatologie des patients présentant une tendinopathie patellaire supérieure. Matériels et Méthodes : Vingt patients atteints d’une tendinopathie patellaire supérieure, rebelle aux traitements conservateurs classiques depuis au moins 3 mois, ont bénéficié d’une évaluation du statut algo-fonctionnel (EVA, algomètre de pression, VISA-P et IKDC) et des performances physqiues (isocinétique et optojump), ainsi que d’un bilan d’imagerie (échographie et IRM). Ces analyses ont été réalisées en pré-injection ainsi qu’aux 6èmeet 12èmesemaines post-injection. Le test isocinétique évaluait la force des quadriceps et des ischios-jambiers des deux membres suivant différentes modalités (C60°/sec, C240°/sec et E30°/sec). Le test Optojump évaluait la détente et la puissance musculaire par la mesure de la hauteur de saut via deux modalités («Counter Movement Jump » et « Drop Jump »). Le PRP est obtenue à l’aide d’une machine d’aphérèse (COM.TEC, Fresenius-Kabi), permettant d’obtenir une concentration plaquettaire reproductible d’un patient à l’autre, en l’absence quasi totale de globules rouges et blancs. L’infiltration intratendineuse de PRP (6mL) est réalisé à la pointe de la rotule in loco dolenti sans anesthésie locale. Résultats : Les résultats de notre expérimentation démontrent qu’une seule injection locale de PRP accompagnée d’un programme de rééducation excentrique améliore significativement la cicatrisation du tendon patellaire au niveau du score EVA, de l’algomètre de pression, des scores VISA-P et IKDC. Lors du test isocinétique, seuls l’augmentation du MFM des ischios jambiers en C240°/sec, de la différence bilatérale des ischios jambiers en C60°/sec ainsi que de l’EVA en E30°/sec était significative. Les résultats optojump en terme de détente et puissance musculaire ne montrent pas d’amélioration des performances. Néanmoins, l’EVA du « Counter Movement Jump » se voit significativement diminuée après l’infiltration. Enfin, les résultats de l’imagerie (échographie et IRM) ne démontrent pas de modification significative du tendon. Conclusions : L’injection locale de PRP dans le cadre de tendinopathies patellaires supérieure permet une diminution de la symptomatologie douloureuse à 6 semaines, se poursuivant à 12 semaines. La performance fonctionnelle et l’imageries, quant à elles, ne sont pas modifiées. [less ▲]

Bone marrow stromal cells are adult multipotent cells that represent an attractive tool in cellular therapy strategies. Several studies have reported that in vitro passaging of mesenchymal stem cells alters the functional and biological properties of those cells, leading to the accumulation of genetic aberrations. Recent studies described bone marrow stromal cells (BMSC) as mixed populations of cells including mesenchymal (MSC) and neural crest stem cells (NCSC). Here, we report the transformation of NCSC into tumorigenic cells, after in vitro long-term passaging. Indeed, the characterization of 6 neural crest-derived clones revealed the presence of one tumorigenic clone. Transcriptomic analyses of this clone highlighted, among others, numerous cell cycle checkpoint modifications and chromosome 11q down-regulation (suggesting a deletion of chromosome 11q) compared with the other clones. Moreover, unsupervised analysis such as a dendrogram generated after agglomerative hierarchical clustering comparing several transcriptomic data showed important similarities between the tumorigenic neural crest-derived clone and mammary tumor cell lines. Altogether, it appeared that NCSC isolated from adult bone marrow represents a potential danger for cellular therapy, and consequently, we recommend that phenotypic, functional and genetic assays should be performed on bone marrow mesenchymal and neural crest stem cells before in vivo use, to demonstrate whether their biological properties, after ex vivo expansion, remain suitable for clinical application.

Introduction : Le projet TADAM, une étude contrôlée randomisée, comparait un nouveau traitement assisté par héroïne avec des traitements existants par méthadone à Liège, en Belgique. Nous avons réalisé une étude qualitative sur l'attitude des personnes dépendantes de l'héroïne envers ce type de projet, ainsi que sur l'attitude des intervenants d'institutions de soins travaillant avec ces personnes Méthode : Avant qu'un patient ne soit inclus dans le projet TADAM, il lui était demandé d'expliquer pourquoi il souhaitait rentrer en traitement (n=80). Des interviews ont également été réalisées auprès de consommateurs d'héroïne non inclus dans le projet, avant la période d'inclusion (n=65), au milieu de celle-ci (n=30) et dans ses derniers mois (n=23). Pendant le projet, des interviews ont également été réalisées auprès d'intervenants travaillant dans des institutions de soins pour personnes dépendantes de substances, soit de manière individuelle (n=10), soit en groupe (n=6) pour connaître leur attitude face au projet TADAM. Résultats : De nombreux patients souhaitaient rentrer dans ce projet pour améliorer leurs conditions de vie. La raison principale de ne pas rentrer dans ce type de traitement était la peur de devenir plus dépendant. Cette raison était renforcée par le fait que le traitement par héroïne proposé ne durait que 12 mois et les patients s'inquiétaient de leur situation après ce traitement : ils avaient peur d'être plus dépendants et donc dans une situation plus difficile qu'avant le traitement. L'attitude des intervenants étaient plutôt favorable mais prudente. Conclusion : Contrairement aux craintes préalables, les usagers d'héroïne ne se précipitent pas en masse et sans réfléchir vers un traitement assisté par héroïne. Certains réfléchissent longtemps avant de s'y engager. Une information précise et un traitement sans durée minimum sont nécessaires. [less ▲]

The gonadosomatic index at spawning, absolute fecundity, and egg size for the female sexual products as well as the density and consistency of semen for the male sexual products were examined in cultured Abramis brama 9 Blicca bjoerkna F1 hybrids and compared with the parental species at their first sexual maturity. Females ovulated under environmental conditions, and their eggs were weighed, counted and measured. Semen of males was macroscopically examined and spermatozoa counted using a hemocytometer. Results revealed that hybridization affected the quality of female and male gametes but with an overlap between hybrids and parents. The gonadosomatic index and fecundity were significantly lower than those of parental species. Egg sizes in hybrids showed a parental effect but to the benefit of hybrids. Semen of hybrids was more diluted which was classified into two groups: the white semen overlapping slightly with parents and the aqueous without any overlap with parents. Overlapped areas between hybrids and parents in term of quality of sexual products could translate that females and males of these hybrids have the biological capacity to produce high quality gametes and thus, a greater chance to produce F2 and backcross generations in rivers.

Little by little, nanotechnology has emerged amid enormous anticipations and fantastic promises of new materials, aspiring to manipulate our world “atom by atom.” While these grand visions continue to capture the imaginations of various audiences—and continue to be contested, as well—nanotechnology has developed into more than that. During the last two decades, many research programs and industrial R&D expenditures have resulted in actual products and tangible innovations. Nanotechnology, it seems, is expanding. But what does it mean to say that nanotechnology is expanding? [less ▲]

This symposium proposes presentations related to nurse educators competencies and the challenges links to their new roles. The evolution of the nurses training at the European level asks the teacher to develop high-level disciplinary skills but also educational skills. There are lots of challenges to develop nurse educator competencies. The role of the teachers is not any more to transmit disciplinary knowledge but to become experts in group management, colleagues teamwork, reflective practice, and construction of active learning situations in a socio constructivist model. These changes of roles also have an impact on the professional identity of the teachers. The various presentations will approach successively these ideas: 1. A proposal for a Competencies Benchmarking of Nurse Educators The aim of this presentation is to characterize the nursing teachers concepts on their professionalism,roles, competences and their identities construction. 2. Educational knowledge in teaching in nursing This presentation examine the teachers conceptions about teaching nursing and professional knowledge about teaching in higher education. 3. Construction of teaching/learning to care from the perspective of nursing teacher This presentation analyses the facilities and difficulties of nurse teacher in their role. 4. The OSCE, an educational project who support the development of the nurse teacher competencies A model for the implementation of a reflexive approach for the nursing training: challenges for the nurse teachers [less ▲]

Aim. The objective of this study was to use in vivo PET/CT imaging as a validation tool for a novel human colorectal carcinoma model being developed in chicken chorioallantoic membrane (CAM). For this initial pilot study a cell line modeling colon cancer was selected and imaged using [18F]fluorodeoxyglucose (FDG). <br />Materials and methods. A window was made in the shell of fertilized chicken eggs and 3x106 SW1222 human colorectal carcinoma cells were implanted at day 10 post-fertilization. On day 17 the shell window was enlarged to allow direct injection of FDG (12.2 ± 4.5 MBq/egg) into a CAM blood vessel. During injection the egg was warmed on a heating pad. A mixture of ketamine/medetomidine (50 :1 mg/ml, 0.2 ml/egg) was injected into the albumin in some eggs to assess the effect of anesthesia. After FDG injection the egg was returned to the incubator for a 45 min uptake period before imaging. Imaging was performed on a Siemens Focus 120 microPET with structural CT on a General Electric eXplore CT120. A Minerve cell system allowed reproducible positioning between modalities. PET data was acquired in list mode before histogramming into a single 10 min frame for reconstruction using a 3D maximum a posteriori (MAP) method with all corrections except scatter. A standard 100 µm (theoretical) image resolution protocol (70 kV, 50 mA, 32 ms, 220 views) was used to obtain structural CT data. Image coregistration was performed in PMOD version 3.3. In a separate egg, the influence of added contrast on the CT data was investigated by adding iodinated contrast agent (Iobitridol 35 mgI/ml) to the albumin. <br />Results. FDG uptake was clear in chick and tumor, with notably high uptake at the major joints. Tumors were identified by localization of FDG uptake on the surface of the CAM. A lack of soft tissue contrast between tumor, CAM and albumin made precise structural identification of the tumor difficult. Anesthesia was crucial to image quality in both PET and CT. CT contrast between the soft tissues of the chick and surrounding albumin/structures was improved by addition of contrast agent. <br />Conclusion. For the first time we demonstrate successful imaging of FDG uptake in a human colorectal carcinoma chicken CAM model in ovo. Methods to improve structural data are under investigation and will be used in further studies. With such improvement, this model could be of great value to PET oncology imaging. [less ▲]
