abstract = {Epidemiological studies suggest that maternal undernutrition sensitises to the development of chronic adult diseases, such as type 2 diabetes, hypertension and obesity. although the physiological mechanisms involved in this ‘perinatal programming’ remain largely unknown, alterations of stress neuroendocrine systems such as the hypothalamic-pituitary-adrenal (hpa) and sympathoadrenal axes might play a crucial role. despite recent reports showing that maternal perinatal undernutrition disturbs chromaffin cells organisation and activity in male rats at weaning, its long-term effects on adrenal medulla in adult animals are unknown. using a rat model of maternal perinatal 50% food restriction (fr50) from the second week of gestation until weaning, histochemistry approaches revealed alterations in noradrenergic chromaffin cells aggregation and in cholinergic innervation in the adrenal medulla of 8-month-old fr50 rats. electron microscopy showed that chromaffin cell granules exhibited ultrastructural changes in fr50 rats. these morphological changes were associated with reduced circulating levels and excretion of catecholamines. by contrast, catecholamine plasma levels were significantly increased after a 16 or 72 h of fasting, indicating that the responsiveness of the sympathoadrenal system to food deprivation was accentuated in fr50 adult rats. among 384 pituitary adenylate cyclase-activating polypeptide-sensitive genes, we identified 129 genes (33.6%) that were under expressed (ratio < 0.7) in fr50 animals. a large number of these genes are involved in cytoskeleton remodelling and vesicle trafficking. taken together, our results show that maternal perinatal undernutrition programmes adrenomedullary function and gene expression in adult male rats. because catecholamines contribute to metabolic homeostasis, as well as arterial blood pressure regulation, the alterations observed in the adrenal medulla of adult male fr50 rats may participate in the programming of chronic adult diseases},

abstract = {In orogenic systems, thrust faults play a major role in stacking different tectonic units and may act as conduits for the expulsion of large amounts of fluid of different origins (metamorphic, diagenetic, meteoric). this study focuses on the monte perdido thrust unit emplaced in the paleogene jaca thrust-sheet-top basin, in the sw-central pyrenees. we aim to decipher the mechanisms and p-t conditions of deformation in fault zones and characterize the related fluid involvement, through combined microstructural, geochemical and microthermometry analyses. two thrust faults cutting platform limestones, marls and siliciclastic turbidites of the lower part of the basin-fill (paleocene–lower eocene) have been studied. the fault zones are characterized by metre-thick shear zones with highly deformed, foliated clay-rich sediments. foliation is underlined by preferentially oriented phyllosilicates. several generations of shear and extension calcite, quartz and chlorite-bearing veins attest to fluid-rock interactions during a multi-stage deformation. microstructural observations and stable isotope analyses on calcite from veins and host sediments suggest that deformation was aseismic and dominated by diffusive mass transfer from pressure solution sites along cleavage and stylolites to the precipitation sites in veins, with mineralizing fluids in equilibrium with the host sediments. our results suggest an essentially closed hydrologic system, and imply the absence of significant fluid flow along the studied fault zones. microthermometric study on fluid inclusions present in calcite and quartz veins, and calcite-quartz oxygen isotopic fractionation determined for the first generation shear veins, allow a geothermal gradient of 34â â°c/km to be estimated. analytical results demonstrate an evolution of the fault zones in three stages. the first stage was related to the emplacement of the monte perdido thrust unit during the middle eocene at a temperature of ∼208â â°c and a burial depth of ∼5.7â km. the second stage corresponds to a fault reactivation at a temperature of ∼240â â°c and a burial depth of ∼6.5â km. the latter deformation may have been related to folding of the monte perdido thrust unit during the emplacement of the underlying gavarnie thrust unit during the late eocene–early oligocene, with deeper burial resulting from aggradation of the thrust-sheet-top basin-fill. the last event corresponds to the formation of a dilatant vein system likely related to the exhumation of the massif. %z acl %u http://www.sciencedirect.com/science/article/pii/s0191814111001039 %+ %^},

abstract = {In france and all over the world, there is no systematic data available on the quality (fertility and contamination) of garden soils. nevertheless, there is a growing need for a typology and for a method dedicated to national and international garden soil survey. this inventory is much needed in the context of environmental risk assessment, to predict the potential impact on human health of the direct contact with garden soils and of the consumption of vegetables from gardens. the state of the art on the international knowledge on garden soils, gardening practices and food production, shows that gardens remain poorly known and very complex ecological, economical and social systems. their global quality is the result of a wide number of factors including environment, history, specific characteristics of the gardens, gardeners and their practices, plant and/or animal productions and socio-economic context. the aim is then to better know the determinism of the agronomic, environmental and sanitary properties of gardens as a function of gardening practices and their impact on the quality of soils and plants. we propose a definition of “garden” and more generally of all the field “garden”. the system “garden” is represented by attributes (soil and plant characteristics) and factors with various impacts (e.g. environment > soil parent material > former land uses > age and sex of gardener > gardening practices > socio-professional group > type and proportion of productions > climate > age of the garden > size of the garden > education, information > cultural origin > functions of the garden > regulations). a typology of gardens including 7 selected factors and associated categories and a method for describing, sampling and characterizing a population of gardens representative (for a country) are proposed. based on the statistical analysis and data mining on regional databases, we have determined and proposed an optimum size for the collected population of garden soils. the analysis of a dataset of garden soils characteristics using data mining lead to regression tree models enabling us an easy understanding of the results on the “garden” system (e.g. predict total metal concentrations from agronomic parameters and land-use, percentage of coarse fraction and percentage of technogenic materials in garden soils). the discussion of the results of data mining highlights the main indicators of soil quality and the method for a survey of garden soils is proposed. these results and the resulting approach might be validated and used on a worldwide scale to collect garden soil samples with the objective of agronomic, environmental and sanitary studies adapted to this type of urban agriculture.},

abstract = {Aided phytostabilisation is a cost efficient technique to manage metal contaminated areas, especially in the case of extensive pollution. however, plant establishment and survival in highly metal-contaminated soils is crucial for phytostabilisation success, as metal toxicity for plants is widely reported. appropriate phytostabilisation technique should also limit metal transfer through the food chain. in this context, this study aimed at evaluating the long-term efficiency of aided phytostabilisation on former agricultural soils highly contaminated with cadmium, lead and zinc. the influence of afforestation and fly ash amendments to reduce metal phytoavailability was investigated as well as their effects on plant development. before being planted with a tree mix, the study site was divided into three plots: a reference plot with no amendment, the second amended with silico-aluminous fly ash and the third with sulfo-calcic fly ash. our data show that, unlike salix alba and quercus robur, alnus glutinosa, acer pseudoplatanus and robinia pseudoacacia have well grown on the site and accumulated overall quite small quantity of metals in their leaves and young twigs. this suggests that these three species are suitable for phytostabilisation of metal contaminated soils. after eight years, results also demonstrated that fly ash amendments strongly decreased te availability to a. glutinosa, a. pseudoplatanus and r. pseudoacacia, and translocation to above-ground parts. these decreases fit well together with the cacl2 extractability depletion of metal in amended soils. if both fly ashes are interesting to decrease cd, pb and zn concentrations in above-ground parts of trees, the sulfo-calcic ash is more efficient.},

abstract = {Sustainable management of large surface areas contaminated with trace elements is a real challenge, since currently applied remediation techniques are too expensive for these areas. aided phytostabilisation appears to be a cost efficient technique to reduce metal mobility in contaminated soils and contaminated particle spread. in this context, this study aimed at evaluating the long-term efficiency of aided phytostabilisation on former agricultural soils highly contaminated with trace elements. the influence of afforestation and fly ash amendments to reduce metal mobility was investigated. before being planted with a tree mix, the study site was divided into three plots: a reference plot with no amendment, the second amended with silico-aluminous fly ash and the third with sulfo-calcic fly ash. after eight years, some soil physico-chemical parameters, including cadmium (cd), lead (pb) and zinc (zn) extractability were modified. in particular, ph decreased on the whole site while organic carbon content increased. the alteration of these parameters influencing trace element mobility is explained by afforestation. over time, concentrations of cacl2-extractable metals increased and were correlated with the soil ph decrease. in the amended soils, extractable cd, pb and zn concentrations were lower than in the reference soil. the results indicated that the two fly ashes buffered natural soil acidification due to vegetation development and limited trace element mobility and thus could limit their bioavailability. for long-term phytostabilisation, special attention should be focused on the soil ph, metal mobility and phytoavailability analysis.

abstract = {New polymers were used as catalysts for the removal of dissolved oxygen in boiler water. these polymers, based upon hydroquinone-quinone redox system, were prepared by polymerization of methyl 4-(2,5- dimethoxybenzyl)cinnamate and copolymerization of this monomer with 4-(40-vinylphenethyl)-1,10-phenanthroline. the resulting product was used to synthesize polymers containing transition metal ions. nuclear magnetic resonance, infrared spectroscopy, and elemental analysis were achieved to characterize monomers and/or electron- transfer polymers. these polymers were used for the removal of oxygen from water. it was shown that the oxygen content was reduced to less than 0.1 mg l in 70 s. based on the obtained results, the redox capacity of two polymers were determined. it was established that the poly-4-(2,5-dihydroxybenzyl)cinnamic acid reached a redox capacity of 69.7 mg of o2 per gram of polymer.},

abstract = {Les teneurs en cadmium de solutions aqueuses contaminees a des teneurs croissantes en arsenic ont ete mesurees a l’aide d’un spectrophotome`tre d’absorption atomique equipe d’une flamme et d’un four electrothermique. pour chacune des techniques d’atomisation, a ete evaluee une me´thode de correction du bruit de fond base´e sur le renversement de spectre et connue sous le nom de « high-speed self-reversal method », au regard d’une autre methode plus couramment utilisee ne ne´cessitant qu’une lampe au deute´rium et une lampe au cadmium. en comparaison avec cette me´thode, les re- sultats ont montre que le mode de correction base´ sur le renversement spectral via l’utilisation d’une lampe au cadmium a` cathode creuse pulse´e a` courant variable etait une methode plus approprie´e pour corriger les phe´nome`nes d’interfe´rences causes par l’arsenic (as) lors du dosage du cadmium (cd). il a ete etabli que cette methode permettait de s’affranchir des interferences de l’arsenic pour des ratios [as]/[cd] infe´rieurs a` 50 000.},
