TBS discrimine les femmes avec ostéoporose fracturaire des femmes non ostéoporotiques indépendamment de la DMO, de l'âge et de l'IMC : Etude de la cohorte Ostéo-Mobile Vaud

Introduction. - « Ostéo-Mobile Vaud » est un projet pilote visant àinformer et promouvoir les mesures générales de prévention del'ostéoporose chez les femmes vaudoises de 60 ans et plus. Son butest également d'évaluer le risque de fracture dans cette populationen associant les facteurs de risque cliniques, la mesure de la DMOpar DXA de la colonne lombaire et du fémur proximal (Hologic Discovery),la recherche des fractures vertébrales préexistantes parVFA et une appréciation de la « qualité osseuse » par TBS. Une phaseprospective de 5 ans est prévue. Le Trabecular Bone Score (TBS) estun procédé qui consiste à appliquer un traitement informatique àl'image 2D de projection de la DXA basé sur la quantification desvariations locales de niveaux de gris. Un modèle mathématiquerelie le paramètre TBS avec des paramètres de microarchitecture 3Dtels la connectivité 3D, le nombre de travées et l'espace inter-trabéculaire.Ce modèle fait de TBS une mesure indirecte de microarchitectureosseuse.Résultats. - Fin juillet 2011, 510 femmes de ± 67 ans, IMC ± 26 kg/m2,ont été évaluées. Une ou plusieurs fractures de fragilité ont été rapportéeschez 72 femmes, parmi lesquelles 39 avec fractures vertébrales.TBS diminue avec l'âge (-0.005 par année, p < 0,001) etdiminue en fonction de l'IMC (- 0,011 par kg/m2, p < 0,001). La corrélationentre TBS et la DMO de la colonne lombaire est faible(r = 0,4, p < 0,001) et un grand pourcentage de la variabilité du TBSest indépendant de la DMO (> 84%). TBS discrimine les femmes avecfractures vertébrales des femmes sans fracture vertébrale et lesfemmes avec OP clinique (fractures de fragilité) de celles sans OPclinique. Ce pouvoir discriminatif est indépendant de la DMO de lacolonne lombaire ou du T-score le plus bas, après ajustement pourl'âge et l'IMC.Odd ratio (OR, 95 % IC) pour une diminution d'une déviation standarddu TBS, ajusté pour l'âge, l'IMC et la mesure de DMO :Conclusion. - TBS représente une plus-value par rapport à la DMOdans l'appréciation du risque de fracture chez les femmes vaudoisesde 60 ans et plus.

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae)

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae). The male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend, 1927) is described and illustrated for the first time based on material housed in the entomological collection of Museu Nacional, Rio de Janeiro (MNRJ). This monotypic subgenus has been recorded in the Brazilian Amazon Rainforest, first in the state of Amazonas and now in the state of Pará. The general structure of the male terminalia is similar that of other Lepidodexia, especially of the subgenus Lepidodexia, by the short distiphallus, juxta with apical projection, and vesica with a membranous spinous lobe.

Aspectos hidrológicos en el fondo marino peruano asociados a la Extensión Sur de la Corriente Cromwell (ESCC) entre 3° y 7°S

Para determinar la variabilidad estacional y espacial en el fondo marino del norte peruano, durante los últimos 30 años (1980-2009), se estudió la temperatura y el oxígeno disuelto entre las latitudes 3°-7°S. Se halló una mayor proyección latitudinal del oxígeno disuelto (OD), superior a 1,0 mL/L en la estación de otoño, delimitada por la isoterma de 15 °C al borde de la plataforma. Esta proyección estaría asociada a los flujos subsuperficiales hacia el sur, que constituyen la Extensión Sur de la Corriente de Cromwell (ESCC), a profundidades de 90-180 m. La oxigenación estaría influenciada por el incremento o repliegue de la ESCC presente en el área. La variación media de oxígeno registra valores de 0,7-1,3 mL/L en verano y 0,8-1,6 mL/L en otoño. Paita (5°S) presenta valores promedio de 1,0 mL/L en verano y de 1,4 mL/L en otoño. Los mayores valores de OD se asocian a latitudes menores en ambas estaciones; la estación de otoño presenta los mayores tenores de oxígeno, asociados a una mayor intensidad de la ESCC.

Differential transgene expression profiles in rat brain, using rAAV2/1 vectors with tetracycline-inducible and cytomegalovirus promoters.

The biodistribution of transgene expression in the CNS after localized stereotaxic vector delivery is an important issue for the safety of gene therapy for neurological diseases. The cellular specificity of transgene expression from rAAV2/1 vectors (recombinant adeno-associated viral vectors pseudotyped with viral capsids from serotype 1) using the tetracycline-inducible (TetON) expression cassette in comparison with the cytomegalovirus (CMV) promoter was investigated in the rat nigrostriatal pathway. After intrastriatal injection, although green fluorescent protein (GFP) was expressed mainly in neurons with both vectors, the relative proportions of DARPP-32-positive projection neurons and parvalbumin-positive interneurons were, respectively, 13:1 and 2:1 for the CMV and TetON vectors. DARP32-positive neurons projecting to the globus pallidus were strongly GFP positive with both vectors, whereas those projecting to the substantia nigra pars reticulata (SNpr) were efficiently labeled by the CMV vector but poorly by the TetON vector. Numerous GFP-positive cells were evidenced in the subventricular zone with both vectors. However, in the olfactory bulb (OB), GFP-positive neurons were observed with the CMV vector but not the TetON vector. We conclude that the absence of significant amounts of transgene product in distant regions (SN and OB) constitutes a safety advantage of the AAV2/1-TetON vector for striatal gene therapy. Midbrain injections resulted in selective GFP expression in tyrosine hydroxylase-positive neurons by the TetON vector whereas with the CMV vector, GFP-positive cells covered a widespread area of the midbrain. The biodistribution of GFP protein corresponded to that of the transcripts and not of the viral genomes. We conclude that the rAAV2/1-TetON vector constitutes an interesting tool for specific transgene expression in midbrain dopaminergic neurons.

Condiciones bio-oceanográficas en San José, islas Lobos de Afuera, Perú. 2010

En este estudio se muestra la variabilidad oceanográfica que se presenta en Lambayeque. Se evidenció con la generación del evento frío La Niña, después que se registrara el arribo de ondas Kelvin hacia la costa desde fines del 2009, lo que se llegó a considerar como la ocurrencia de un evento El Niño de intensidad moderada. Esta situación propició que los recursos pesqueros se ausentaran de sus áreas habituales de pesca, sumado a la presencia de oleajes anómalos y fuertes vientos que dificultaron las faenas de pesca. Durante el 2010, la Extensión Sur de la Corriente de Cromwell (ESCC) se presentó moderadamente fortalecida en marzo, evidenciada por la relativa alta concentración de oxígeno disuelto en las áreas más profundas de San José, situación inusual para la época en la zona. La proyección de la ESCC se vio intensificada en abril, pero comenzó a debilitarse en junio hasta ausentarse en noviembre, como se puede deducir de los valores de oxígeno encontrados cerca del fondo durante las prospecciones realizadas.

Émergence du moi cérébral de Theodor Meynert à Antonio Damasio = Emergence of the cerebral self, from Theodor Meynert to Antonio Damasio

Antonio Damasio's works have brought emotions into line with current trends in neuroscience. They are conceived as the addition, to a perception, of the somatic effects it has induced. Nevertheless, this continuous and relatively steady process of body perception has also led to the less-known hypothesis of the "neural self." Behind the explicit and apparently contradictory reference to William James and Sigmund Freud, there lies a common source: Theodor Meynert's conception of a "cortical self." Our aim is to enlight a stream unified around what we call here "cerebral self." The Self is thus considered as the cerebral projection or presentation of the body. The specificity of this notion is particularly highlighted by its confrontation to the closely, yet disembodied, notion of "cerebral subject.". Pour citer cette revue : Psychiatr. Sci. Hum. Neurosci. 9 (2011).

Au commencement était le Verbe: perpétuation de l'oralité du "muet" dans quelques incipit filmiques des premières années du parlant

Partant d'une perspective sémiotique appliquée aux débuts de film pour élargir l'approche à une réflexion historique sur l'intermédialité, cet article examine le postulat selon lequel les spectacles vivants qui précédaient la projection des films dans les années 1920 ont été en quelque sorte « happés » par le discours filmique. A travers l'examen d'un ensemble de films réalisés entre 1927 et 1937 qui accordent dans leurs génériques ou leurs prologues une place prépondérante à l'adresse vocale, l'auteur met en évidence certains phénomènes de résurgence de l'oralité propre à la période « muette », les speaker des premiers talkies endossant une fonction à certains égards similaire à celle du bonimenteur des premiers temps. L'accent est mis sur la production cinématographique de Guitry, dont la passion pour la « théâtralité » l'incite à proposer des formes singulières d'auto-mise en scène et d'adresse au spectateur. La question de la réflexivité des incipit passe également par la prise en compte de la dimension technologique, qui est parfois intégrée au film même, à l'instar de l'ouverture radiophonique de L'Atlantide de Pabst. Ces considérations s'inscrivent plus généralement dans une réflexion sur les diverses imitations de la voix vive à l'ère des technologies de l'audiovisuel.

My research in live drawing and new technologies uses a combination of a human figure in live in composition, overlaid with a digital projection of a second human figure. The aim is to explore, to amplify and thoroughly analyse the search for distinctive identities and graphic languages of representation for live and projected models.

Domain Adaptation in remote sensing: increasing the portability of land-cover classifiers

Among the types of remote sensing acquisitions, optical images are certainly one of the most widely relied upon data sources for Earth observation. They provide detailed measurements of the electromagnetic radiation reflected or emitted by each pixel in the scene. Through a process termed supervised land-cover classification, this allows to automatically yet accurately distinguish objects at the surface of our planet. In this respect, when producing a land-cover map of the surveyed area, the availability of training examples representative of each thematic class is crucial for the success of the classification procedure. However, in real applications, due to several constraints on the sample collection process, labeled pixels are usually scarce. When analyzing an image for which those key samples are unavailable, a viable solution consists in resorting to the ground truth data of other previously acquired images. This option is attractive but several factors such as atmospheric, ground and acquisition conditions can cause radiometric differences between the images, hindering therefore the transfer of knowledge from one image to another. The goal of this Thesis is to supply remote sensing image analysts with suitable processing techniques to ensure a robust portability of the classification models across different images. The ultimate purpose is to map the land-cover classes over large spatial and temporal extents with minimal ground information. To overcome, or simply quantify, the observed shifts in the statistical distribution of the spectra of the materials, we study four approaches issued from the field of machine learning. First, we propose a strategy to intelligently sample the image of interest to collect the labels only in correspondence of the most useful pixels. This iterative routine is based on a constant evaluation of the pertinence to the new image of the initial training data actually belonging to a different image. Second, an approach to reduce the radiometric differences among the images by projecting the respective pixels in a common new data space is presented. We analyze a kernel-based feature extraction framework suited for such problems, showing that, after this relative normalization, the cross-image generalization abilities of a classifier are highly increased. Third, we test a new data-driven measure of distance between probability distributions to assess the distortions caused by differences in the acquisition geometry affecting series of multi-angle images. Also, we gauge the portability of classification models through the sequences. In both exercises, the efficacy of classic physically- and statistically-based normalization methods is discussed. Finally, we explore a new family of approaches based on sparse representations of the samples to reciprocally convert the data space of two images. The projection function bridging the images allows a synthesis of new pixels with more similar characteristics ultimately facilitating the land-cover mapping across images.

Low-dose, simple, and fast grating-based X-ray phase-contrast imaging.

Phase sensitive X-ray imaging methods can provide substantially increased contrast over conventional absorption-based imaging and therefore new and otherwise inaccessible information. The use of gratings as optical elements in hard X-ray phase imaging overcomes some of the problems that have impaired the wider use of phase contrast in X-ray radiography and tomography. So far, to separate the phase information from other contributions detected with a grating interferometer, a phase-stepping approach has been considered, which implies the acquisition of multiple radiographic projections. Here we present an innovative, highly sensitive X-ray tomographic phase-contrast imaging approach based on grating interferometry, which extracts the phase-contrast signal without the need of phase stepping. Compared to the existing phase-stepping approach, the main advantages of this new method dubbed "reverse projection" are not only the significantly reduced delivered dose, without the degradation of the image quality, but also the much higher efficiency. The new technique sets the prerequisites for future fast and low-dose phase-contrast imaging methods, fundamental for imaging biological specimens and in vivo studies.
