A l'heure actuelle, le bioraffinage se présente de plus en plus comme une alternative prometteuse aux filières pétrochimiques puisqu'il vise à la fois le remplacement d'une partie du pétrole comme source d'énergie et le développement de produits chimiques issus de la biomasse (végétale principalement) tels que détergents, produits phytopharmaceutiques, dissolvants, matières plastiques, etc. La valorisation de carbohydrates provenant de matières premières renouvelables fait ainsi actuellement l'objet de nombreuses recherches. Dans ce cadre, la synthèse de nouveaux tensioactifs non ioniques dérivés des acides Dglucuronique et D-galacturonique a été effectuée. [less ▲]

BACKGROUND: Activation and coagulation biomarkers were measured within the Strategies for Management of Antiretroviral Therapy (SMART) trial. Their associations with opportunistic disease (OD) in human immunodeficiency virus (HIV)-positive patients were examined. METHODS: Inflammatory (high-sensitivity C-reactive protein [hsCRP], interleukin-6 [IL-6], amyloid-A, and amyloid-P) and coagulation (D-dimer and prothrombin-fragment 1+2) markers were determined. Conditional logistic regression analyses were used to assess associations between these biomarkers and risk of OD. RESULTS: The 91 patients who developed an OD were matched to 182 control subjects. Patients with an hsCRP level > or =5 microg/mL at baseline had a 3.5 higher odds of OD (95% confidence interval [CI], 1.5-8.1) than did those with an hsCRP level <1 microg/mL (P=.003, by test for trend) and patients with an IL-6 level > or =3 pg/mL at baseline had a 2.4 higher odds of OD (95% CI, 1.0-5.4) than did those with an IL-6 level <1.5 pg/mL (P=.02, by test for trend). No other baseline biomarkers predicted development of an OD. Latest follow-up hsCRP level for those with an hsCRP level > or =5 microg/mL (compared with a level <1 microg/mL; odds ratio [OR], 7.6; 95% CI, 2.0-28.5; [P=.002, by test for trend), latest amyloid-A level for those with an amyloid-A level > or =6 mg/L (compared with a level <2 mg/L; OR, 3.8; 95% CI, 1.1-13.4; P=.03, by test for trend), and latest IL-6 level for those with an IL-6 level > or =3 pg/mL (compared with a level <1.5 pg/mL; OR 2.4; 95% CI, 0.7-8.8; P=.04, by test for trend) were also associated with development of an OD. CONCLUSIONS: Higher IL-6 and hsCRP levels independently predicted development of OD. These biomarkers could provide additional prognostic information for predicting the risk of OD. [less ▲]

The consequences of Hymenoptera venom anaphylaxis are very severe but it is not obvious to predict which reactions will occur in one single patient when he is stung for the second time. For a couple of years, many new laboratory tests have been experimented and many studies published. CAST, BAT, WB, tryptase, sIgE and sIgG4 are the new valuable additional diagnostic tools that can help the decision to perform an immunotherapy or to discontinue this therapy after 3 years. The aim of our study was to determine which could be the profile of a desensitized patient and to screen for good candidates for venom immunotherapy. [less ▲]

In order to model the nitrate concentration of the recharge water in a spatially distributed way for the agricultural areas of the Walloon Region of Belgium, the EPIC model was first adapted to the specific soil description by modifying the reservoir sizes. It was also adapted to the regional crop production by modifying classcrop files in relation with observed data (both aerial and underground crop growth, yield) in wheat, sugar beet, and potato fields. As the vadose zone presents a depth between 1.5 and 104 m in this region, new reservoirs were added according to the geological descriptions available. Deep nitrate transfer was validated in a specific site where cropping history was known. Nitrate nitrogen after harvest in the root zone was validated for wheat within different crop rotations using the first results of a nitrate-monitoring program planned by the authorities to test the effectiveness of the mitigation measures in agriculture. This extended model was also linked to a GIS (geographical information system) using 1 km2-cells. All the required data were rasterised to allow HRU (hydrological response unit) identification within the cells. The cell’s daily water flows are weighted flows of each HRU depending on their relative area within the cell. Water balances at catchment scale allow us to validate the calculation. Taking into account the evolution of distributed land use and observed climatic data, we have built maps of fast indicators and long-term indicators. The first map represents nitrate concentration in the water leaving the root zone and the second one represents the time transfer for nitrate from 1.5 m depth to the groundwater table and nitrate concentration in recharge water. These maps constitute major tools for nitrogen management at a regional level. [less ▲]

Bottom friction modeling is an important step in river flows computation with 1D or 2D solvers. It is usually performed using empirical laws established for uniform flow conditions or a modern approach based on turbulence analysis. Following the definition of the flow validity field of the main friction laws proposed in the iterature, an original continuous formulation has been developed. It is suited to model river flows with a high variability of properties (water depth, discharge, roughness…). The efficiency of this new formulation, theoretically established and numerically adjusted, is demonstrated through various practical applications. [less ▲]

The objective of this paper is to examine nonlinear normal modes and their bifurcations in cyclic periodic structures. The nonlinear normal modes are computed using a numerical technique that combines shooting and pseudoarclength continuation. Unlike perturbation techniques, the resulting algorithm can investigate strongly nonlinear regimes of motion. This study reveals that modal interactions may occur without necessarily having commensurate natural frequencies in the underlying linear system. In addition, a countable infinity of such modal Q2 interactions are shown to exist in the system. [less ▲]

Bovine ghrelin, a 27 amino acid pepticle, has been identified in oxyntic glands of the abomasum. It is an endogenous ligand for growth hormone secretagogue receptor and stimulates food intake and growth hormone secretion. The bovine GHRL gene was completely sequenced and consists of five exons and four introns. Like mouse and human GHRL genes, we found that the bovine GHRL gene also contains a first non-coding exon of 21 bp. The bovine GHRL gene codes for 116 amino acid pepticle named preproghrelin which contains the ghrelin pepticle and another pepticle similar to obestatin. Sequence analysis revealed eight polymorphisms, which are located in the non-coding sequence of the gene. [less ▲]

In most aphid species, the volatile sesquiterpene (E)-beta-farnesene (E beta f) is released as an alarm pheromone in response to predation and is also emitted continuously at low levels. Some aphid predators use E beta f as a foraging cue, suggesting that the benefits to aphids of signaling via E beta f must be weighed against the cost of increasing apparency to natural enemies. To determine whether aphids vary E beta f production in response to features of their social environment, we compared the production of E beta f by Acyrthosiphon pisum (Harris) individuals reared in isolation with that of individuals reared among conspecifics or individuals of a different aphid species, Myzus persicae. Production of E beta f by A. pisum reared in isolation was significantly lower than that of aphids reared among conspecifics or among M. persicae individuals. When we reared A. pisum individuals in isolation but exposed them to odors from an aphid colony, E beta f production was similar to that of aphids reared among conspecifics, suggesting that aphids use a volatile cue to assess their social environment and regulate their production of alarm pheromone. It is likely that this cue is E beta f itself, the only volatile compound previously found in headspace collections of A. pisum colonies. Finally, we examined the attraction of a predatory hoverfly, which uses E beta f as a foraging cue, to groups of aphids reared in isolation or among conspecifics and found that groups comprising individuals reared in isolation were significantly less attractive to the predator, suggesting that the observed variation in E beta f production may be ecologically relevant.
