Aav-based gene therapy approaches for the treatment of canavan disease
2013
Background: The enzyme Aspartoacylase (ASPA) is normally expressed in oligodendrocytes, the myelin-forming cells in the central nervous system (CNS). ASPA gene mutations cause Canavan Disease (CD), a devastating neurological disorder characterized by psychomotor retardation, and spongiform degeneration of central white matter in affected children. The lack of ASPA leads to the enrichment in its substrate N-acetyl aspartate (NAA) which is a biomarker of CD. With no available treatment and a pathology restricted to the CNS CD has been trialled by gene therapy. However, gene replacement approaches using neurotropic recombinant adeno-associated viral (rAAV) vectors have proved unsuccessful. It …
SMOS REFLEX 2003: L-band emissivity characterization of vineyards
2005
The goal of the Soil Moisture and Ocean Salinity mission over land is to infer surface soil moisture from multiangular L-band radiometric measurements. As the canopy affects the microwave emission of land, it is necessary to characterize different vegetation layers. This paper presents the Reference Pixel L-Band Experiment (REFLEX), carried out in June-July 2003 at the Vale/spl grave/ncia Anchor Station, Spain, to study the effects of grapevines on the soil emission and on the soil moisture retrieval. A wide range of soil moisture (SM), from saturated to completely dry soil, was measured with the Universitat Polite/spl grave/cnica de Catalunya's L-band Automatic Radiometer (LAURA). Concurre…
On the Use of the Eddy Covariance Latent Heat Flux and Sap Flow Transpiration for the Validation of a Surface Energy Balance Model
2018
Actual evapotranspiration is assessed via surface energy balance at an hourly rate. However, a robust estimation of daily evapotranspiration from hourly values is required. Outcomes of surface energy balance are frequently determined via measures of eddy covariance latent heat flux. Surface energy balance can be applied on images acquired at different times and spatial resolutions. In addition, hourly actual evapotranspiration needs to be integrated at a daily rate for operational uses. Questions arise whether the validation of surface energy balance models can benefit from complementary in situ measures of latent heat flux and sap flow transpiration. Here, validation was driven by image ac…
Latent heat flux variability and response to drought stress of black poplar: A multi-platform multi-sensor remote and proximal sensing approach to re…
2022
Abstract High-throughput mapping of latent heat flux (λET) is critical to efforts to optimize water resources management and to accelerate forest tree breeding for improved drought tolerance. Ideally, investigation of the energy response at the tree level may promote tailored irrigation strategies and, thus, maximize crop biomass productivity. However, data availability is limited and planning experimental campaigns in the field can be highly operationally complex. To this end, a multi-platform multi-sensor observational approach is herein developed to dissect the λET signature of a black poplar (Populus nigra) breeding population (“POP6”) at the canopy level. POP6 comprised more than 4600 …

La carte, outil de diagnostic et de prospective pour les politiques scolaires
2006
ACL; International audience; Une étude de la localisation de nouveaux collèges dans le bassin de formation de Gap, en croissance démographique, montre que la carte constitue un robuste outil de diagnostic et de prospective pour les politiques scolaires. Tout d'abord, la carte, outil de recherche, mesure l'accessibilité des collèges et leurs aires de recrutement. Puis, vecteur de communication entre acteurs, elle "donne à voir", en le matérialisant, le territoire scolaire aux élus en charge des collèges, en modifiant leurs représentations de l'espace. Enfin, elle permet d'asseoir des scénarios.
Reseña a Rathmann, Michael: Tabula Peutingeriana. Die einzige Weltkarte aus der Antike. Philipp von Zabern Verlag, 2017, 112 pp., ISBN: 978-3-8053-51…

La Tabula Peutingeriana es un relevante documento gráfico que ha sido fechado mediante criterios paleográficos hacia el año 1200. En la actualidad se conserva en la vienesa Biblioteca Nacional de Austria, catalogado como Codex Vindobonensis 324, y debe su peculiar adjetivo al apellido del humanista alemán Konrad Peutinger (1465-1547), quien en 1511 obtuvo permiso del emperador Maximiliano I para im - primir las primeras copias de las hojas del pergamino. La importancia de esta obra viene dada por el hecho de recoger el contorno del Imperio romano (extendiéndo- se incluso más allá de sus fronteras orientales), con indicación mediante dibujos de sus principales ciudades y accidentes geográfic…
