Quantification of land-atmosphere exchanges of water, energy and carbon dioxide in space and time over the heterogeneous Barrax site

2008

International audience; To advance our understanding of land-atmosphere exchanges of water, energy and carbon dioxide (CO2) in space and time over heterogeneous land surfaces, two intensive field campaigns were carried out at the Barrax agricultural test site in Spain during 12-21 July 2004 (SPARC 2004) and 8-14 July 2005 (SEN2FLEX 2005) involving multiple field, satellite and airborne instruments for characterizing the state of the atmosphere, the vegetation and the soil from the visible to the microwave range of the spectrum. Part of the experimental area is a core site of area 25 km2, within which numerous crops are grown, on both irrigated and dry land, alongside fields of bare soil. Th…

Differential responses of bacterial and archaeal groups at high taxonomical ranks to soil management

2010

Little is known about abundances of the major bacterial taxa in agricultural soils and how they are affected by fertilization or other agricultural practices. Our aim was to determine the abundance and relative distribution of several bacterial phyla and one class, as well as the archaeal and crenarchaeal communities, and how they were affected by different fertilization regimes to examine whether specific responses of microorganisms could be identified at these high taxonomic ranks. We used real-time PCR with taxa specific primers to quantify the abundance of the Actinobacteria, Acidobacteria, Bacteriodetes, Firmicutes, Gemmatimonadetes, Verrucomicrobia, Alphaproteobacteria and Crenarchaeo…

Systemic risk factors for peri-implant bone loss: a systematic review and meta-analysis

2014

The aim of this study was to determine the influence of patient-related systemic risk factors (systemic disease, genetic traits, chronic drug or alcohol consumption, and smoking status) on peri-implant bone loss at least 1 year after implant installation and prosthetic loading. An electronic search was performed of MEDLINE, EMBASE, and The Cochrane Central Register of Controlled Trials up to January 2012. One thousand seven hundred and sixty-three studies were identified. After applying a three-stage screening process, 17 articles were included in the qualitative analysis, but only 13 in the quantitative analysis, since smoking was a common exposure. The meta-analysis of these 13 studies (4…

Puente a trasplante cardiaco con oxigenación de membrana extracorpórea

2012

PUENTE A TRASPLANTE CARDIACO CON OXIGENACIÓN DE MEMBRANA EXTRACORPÓREA Objetivos: Los nuevos sistemas de Oxigenación de Membrana Extracorpórea (ECMO) han presentado un desarrollo tecnológico notable, fundamentalmente debido a la incorporación de oxigenadores y bombas centrífugas de larga duración, lo cual ha conducido a una importante mejoría en la supervivencia de los pacientes en shock cardiogénico refractario tratados con este tipo de asistencia mecánica circulatoria de corta duración. La implantación de este dispositivo por vía periférica de forma sencilla, rápida y poco agresiva en estos pacientes en shock cardiogénico con signos incipientes de fracaso multiorgánico puede mejorar su su…

Carbohydrates in plant immunity and plant protection: roles and potential application as foliar sprays.

2014

International audience; Increasing interest is devoted to carbohydrates for their roles in plant immunity. Some of them are elicitors of plant defenses whereas other ones act as signaling molecules in a manner similar to phytohormones. This review first describes the main classes of carbohydrates associated to plant immunity, their role and mode of action. More precisely, the state of the art about perception of "PAMP, MAMP, and DAMP (Pathogen-, Microbe-, Damage-Associated Molecular Patterns) type" oligosaccharides is presented and examples of induced defense events are provided. A particular attention is paid to the structure/activity relationships of these compounds. The role of sugars as…
