The kinetic constant kos a for outer-sphere nanoparticle-metal association is obtained from the sum of the contributions stemming from all reactive sites, each evaluated from the corresponding incoming flux of metal ions derived from steady-state Poisson-Nernst-Planck equations. Illustrations are provided to capture the basic intertwined impacts of particle size, overall particle charge, spatial heterogeneity in site distribution, type of particle (hard, core-shell or porous) and concentration of the background electrolyte on k(a)(os). As a limit, kos a converges with predictions from previously reported analytical expressions derived for porous particles with low and high charge density, cases that correspond to coulombic and mean-field (smearedout) electrostatic treatments, respectively. The conditions underlying the applicability of these latter approaches are rigorously identified in terms of (i) the extent of overlap between electric double layers around charged neighbouring sites, and (ii) the magnitude of the intraparticulate metal concentration gradient.

During the Amundsen scientific cruise, eight sites distributed across the Canadian Arctic and sub-Arctic regions were selected to highlight sensitive areas affected by either atmospheric deposition, ocean current, river drainage, or anthropogenic activities. As part of the Canadian-led ArcticNet research program, this study aims to monitor and to better understand potential changes likely to impact the Arctic. Materials and methods Surface sediments were investigated with bioanalytical tests to assess sediment toxicity. Testing of sediment elutriates was undertaken with the ARTOXKIT M, Microtox liquid phase (MLPA), and ROTOXKIT M toxicity assays, while whole sediment testing was carried out with the Microtox solid phase assay (MSPA) toxicity test procedure. Sediment mercury (Hg) content was also determined in each sample since Hg transport and toxicity is specifically an important issue in the Arctic and is generally a key indicator of the pollution status in many aquatic ecosystems. Results and discussion Based on bioassay results and sediment granulometric criteria, these Arctic sediments must be considered nontoxic. However, based on MSPA half maximal inhibitory concentrations (IC50s) and/or MLPA threshold effect concentration (TEC) values, some degree of toxicity may be measureable particularly in the sediments located in southern and northeast Hudson Bay. The Hudson Bay watershed drains 30% of Canadian rivers and extends to northern USA. Despite the large Hg concern in the Arctic, the input of local or long-range Hg sources does not appear to be a contributing factor to sediment toxicity. Conclusions These initial results are valuable in that they set baseline quality levels for these sediments as of 2005. As such, future comparisons can be made to assess temporal and spatial trends. Human activity and climate change is expected to impact these regions in the future, resulting in further reduction of sea ice extent, access to new Arctic seaways, and drilling associated with the exploitation of natural resources.", "publicationTitle": "JOURNAL OF SOILS AND SEDIMENTS", "publisher": "", "place": "", "date": "janvier 2014", "volume": "14", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "196-203", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1007/s11368-013-0792-1", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1439-0108", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Canadian Arctic" }, { "tag": "Hudson Bay" }, { "tag": "Mercury" }, { "tag": "Northwest Passage" }, { "tag": "Sediments" }, { "tag": "Toxicity" } ], "collections": [ "GH7VBWMX" ], "relations": {}, "dateAdded": "2014-10-23T13:06:25Z", "dateModified": "2014-10-23T13:06:25Z" } }, { "key": "9EAIKA7N", "version": 6, "library": { "type": "group", "id": 275388, "name": "LIEC", "links": { "alternate": { "href": "https://www.zotero.org/groups/liec", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275388/items/9EAIKA7N", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/liec/items/9EAIKA7N", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Duval and Rotureau", "parsedDate": "2014", "numChildren": 0 }, "data": { "key": "9EAIKA7N", "version": 6, "itemType": "journalArticle", "title": "Dynamics of metal uptake by charged soft biointerphases: impacts of depletion, internalisation, adsorption and excretion", "creators": [ { "creatorType": "author", "firstName": "Jerome F.

The formalism integrates the interplay over time between bulk metal depletion, metal adsorption, metal excretion (efflux) and transport of metals by conductive diffusion toward the metal-consuming biomembrane. The model further involves the basic physicochemical features of the microbial interphase in terms of size, distribution of electrostatic charges and thickness of peripheral soft surface appendage. A generalization of the Best equation is proposed and leads to the expression of the time-dependent concentration of metal ions at the active membrane surface as a function of bulk metal concentration. Combination of this equation with the metal conservation condition over the sample volume allows a full evaluation of bulk metal depletion kinetics and the accompanying time-dependent uptake and excretion fluxes as a function of metal-microorganism electrostatic interaction, microbe concentration and relevant biophysicochemical features of the interphase. Practically tractable expressions are derived in the limit where the Biotic Ligand Model (BLM) is obeyed and in situations where conductive diffusion transport of metals significantly determines the rate of biouptake. In particular, the plateau value reached at sufficiently long times by bulk metal concentration is rigorously expressed in terms of the key parameters pertaining to the adsorption process and to the kinetics of metal uptake and excretion.

Among colloidal matters of interests, clay minerals play a major role in metal complexes formation and sorption. The aim of this study is to analyze the dynamic speciation of metal in the presence of clay as colloidal ligand. This work is achieved by means of two complementary electroanalytical techniques: Absence of Gradients and Nernstian Equilibrium Stripping (AGNES) is used for the direct determination of the free metal in solution and stripping chronopotentiometry at scanned deposition potential (SSCP) is applied for the dynamic speciation analysis. The measured response of SSCP reflects the flux properties (limiting transport or kinetic fluxes) of metallic species and allows the determination of thermodynamic constants and analytical lability features of metal complexes. In addition to that, one of the main interests of using such a technique lies in the fact that analyses are achieved in metal concentrations of environmental relevance (from millimolar to nanomolar). For anisotropic and chemically heterogeneous particles such as clay particles, this study demonstrates the possibility to obtain useful information as the determination of diffusion coefficients of particles as well as the description of dynamic behavior of metal species as a function of physicochemical conditions of the suspension. In this regard, this study shows that the sorption of cadmium by clays can be described as a chemically homogeneous and labile system along a large range of pH whereas lead sorption shows some heterogeneity aspects, while remaining SSCP-labile.

Chemical analysis using inductively coupled plasma mass spectrometry (ICP-MS) was carried out on three compartments-waters, suspended materials, and sediments-along the river linear. The variations of metallic trace element concentrations along the river were shown to be partially related to external inputs (industrial and domestic wastewaters and urban surfaces leaching). However, some discrepancies of element partitioning were evidenced. Pb, Cu, and Mn tend to concentrate in suspended particulate and in dissolved fraction, while Cr and As follow the trend of Fe and concentrate within sediments of the most downstream station, just before the junction with Moselle waters. Zn appears strongly associated to iron-rich particles, resulting in a decrease of its concentration in waters for the last station. Along the Fensch linear, the variation of metal partitioning between water and particulate phases is accompanied with strong modifications of the nature and mineralogy of iron-rich particles, as evidenced by microanalyses using electron and X-ray beams. The combination of bulk analyses using ICP-MS and microanalyses applied to the three compartments allowed us to propose a three-step process “settling-weathering-resuspension” to explain Zn partitioning.", "publicationTitle": "ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH", "publisher": "", "place": "", "date": "février 2014", "volume": "21", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "2744-2760", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1007/s11356-013-2192-x", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0944-1344", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Iron" }, { "tag": "Metallic contaminants" }, { "tag": "Microanalyses" }, { "tag": "Microspectroscopy" }, { "tag": "River particles" } ], "collections": [ "GH7VBWMX" ], "relations": {}, "dateAdded": "2014-10-23T13:06:25Z", "dateModified": "2014-10-23T13:06:25Z" } }, { "key": "FJRI7N73", "version": 6, "library": { "type": "group", "id": 275388, "name": "LIEC", "links": { "alternate": { "href": "https://www.zotero.org/groups/liec", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275388/items/FJRI7N73", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/liec/items/FJRI7N73", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Decarreau et al.", "parsedDate": "2014-06", "numChildren": 0 }, "data": { "key": "FJRI7N73", "version": 6, "itemType": "journalArticle", "title": "STUDY OF LOW-PRESSURE ARGON ADSORPTION ON SYNTHETIC NONTRONITE: IMPLICATIONS FOR SMECTITE CRYSTAL GROWTH", "creators": [ { "creatorType": "author", "firstName": "Alain", "lastName": "Decarreau" }, { "creatorType": "author", "firstName": "Sabine", "lastName": "Petit" }, { "creatorType": "author", "firstName": "Pauline", "lastName": "Andrieux" }, { "creatorType": "author", "firstName": "Frederic", "lastName": "Villieras" }, { "creatorType": "author", "firstName": "Manuel", "lastName": "Pelletier" }, { "creatorType": "author", "firstName": "Angelina", "lastName": "Razafitianamaharavo" } ], "abstractNote": "Because relatively little information about the crystal-growth process of smectite is available, the process was assessed here by studying the size and shape of nontronite particles synthesized at six different temperatures from 75 to 150 degrees C over a period of 4 weeks.

However, the degree of specialisation of a given taxon for a particular resource (a convenient proxy for studying functional homogenisation) is often described simply as uses the resource' or does not', despite there being an obvious continuum of degrees of specialisation by species for many different resources. Moreover, the non-randomness of the relationship between resource specialisation by the species making up a community and anthropogenic stress has been rarely tested. In this study, a framework based on fuzzy-coded traits is proposed to calculate a new continuous index of potential specialisation for a variety of taxa in a wide range of ecosystems. The use of this index is illustrated using 10 Eltonian and 11 Grinnellian traits of stream macroinvertebrate assemblages. We tested (i) the significance of the relationships between the average degree of specialisation among the taxa of a community and two types of anthropogenic stress (acidification and organic contamination) at the local scale and (ii) the non-randomness of these relationships. Stress gradients explained, through non-random effects, a rather high proportion of the variability observed in the degree of taxon specialisation, with significant relationships for eight of the 21 traits studied with regard to acidification and for 18 of the 21 traits with regard to organic contamination. Although most of these relationships described functional homogenisation (i.e. decreasing specialisation with increasing stress), increasing specialisation with increasing stress was demonstrated for a few Eltonian traits. We confirmed the importance of indicators of functional homogenisation calculated at the community level when studying the loss of biodiversity due to anthropogenic stress. The assessment of ecological specialisation seems to be a very promising strategy for understanding the effects of habitat impairment on community and ecosystem processes. Moreover, we show that the intensity of functional homogenisation depends on a trade-off between direct' and indirect' effects of stressors, and we consider that more attention should be paid to the mechanisms by which anthropogenic stressors act on taxa.", "publicationTitle": "FRESHWATER BIOLOGY", "publisher": "", "place": "", "date": "mars 2014", "volume": "59", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "584-600", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1111/fwb.12289", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0046-5070", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "biotic homogenisation" }, { "tag": "community ecology" }, { "tag": "conditional inference trees" }, { "tag": "freshwater macroinvertebrate traits" }, { "tag": "null models" } ], "collections": [ "GH7VBWMX" ], "relations": {}, "dateAdded": "2014-10-23T13:06:25Z", "dateModified": "2014-10-23T13:06:25Z" } }, { "key": "D2RUWCS5", "version": 6, "library": { "type": "group", "id": 275388, "name": "LIEC", "links": { "alternate": { "href": "https://www.zotero.org/groups/liec", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/275388/items/D2RUWCS5", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/liec/items/D2RUWCS5", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1721057, "username": "pya", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/pya", "type": "text/html" } } }, "creatorSummary": "Cornut et al.", "parsedDate": "2014-03", "numChildren": 0 }, "data": { "key": "D2RUWCS5", "version": 6, "itemType": "journalArticle", "title": "Aquatic Hyphomycete Species Are Screened by the Hyporheic Zone of Woodland Streams", "creators": [ { "creatorType": "author", "firstName": "Julien", "lastName": "Cornut" }, { "creatorType": "author", "firstName": "Eric", "lastName": "Chauvet" }, { "creatorType": "author", "firstName": "Florian", "lastName": "Mermillod-Blondin" }, { "creatorType": "author", "firstName": "Fiona", "lastName": "Assemat" }, { "creatorType": "author", "firstName": "Arnaud", "lastName": "Elger" } ], "abstractNote": "Aquatic hyphomycetes strongly contribute to organic matter dynamics in streams, but their abilities to colonize leaf litter buried in streambed sediments remain unexplored.

Our field study showed that spore abundance and species diversity were consistently reduced in the interstitial water compared with surface water within three differing streams. Significant differences occurred among aquatic hyphomycetes, with dispersal efficiency of filiform-spore species being much higher than those with compact or branched/tetraradiate spores. This pattern was remarkably consistent with those found in laboratory experiments that tested the influence of sediment pore size on spore dispersal in microcosms. Furthermore, leaves inoculated in a stream and incubated in slow-filtration columns exhibited a fungal assemblage dominated by only two species, while five species were codominant on leaves from the stream-simulating microcosms.

rates from ash and element release rate from the plant litter, as well as quantification of the specific ash contribution to stream water chemistry. The main objective of the study was to provide such knowledge through combination of experimental modelling, field data and end-member mixing analysis (EMMA) of wildfire impact on a watershed scale. The study concerns watershed effects of fire in the Indian subcontinent, a region that is typically not well represented in the fire science literature. In plant litter ash, major elements are either hosted in readily-soluble phases (K, Mg) such as salts, carbonates and oxides or in less-soluble carrier-phases (Si, Ca) such as amorphous silica, quartz and calcite. Accordingly, elemental release rates, inferred from ash leaching experiments in batch reactor, indicated that the element release into solution followed the order K > Mg > Na > Si > Ca. Experiments on plant litter leaching in mixed-flow reactor indicated two dissolution regimes: rapid, over the week and slower over the month. The mean dissolution rates at steady-state (R-ss) indicated that the release of major elements from plant litter followed the order Ca > Si > Cl > Mg > K > Na. R-ss for Si and Ca for tree leaves and herbaceous species are similar to those reported for boreal and European tree species and are higher than that from the dissolution of soil clay minerals. This identifies tropical plant litters as important source of Si and Ca for tropical surface waters. In the wildfire-impacted year 2004, the EMMA indicated that the streamflow composition (Ca, K, Mg, Na, Si, Cl) was controlled by four main sources: rainwater, throughfall, ash leaching and soil solution. The influence of the ash end-member was maximal early in the rainy season (the two first storm events) and decreased later in the rainy season, when the stream was dominated by the throughfall end-member. The contribution of plant litter decay to the streamwater composition for a year not impacted by wildfire is significant with estimated solute fluxes originating from this decay greatly exceed, for most major elements, the annual elemental dissolved fluxes at the Mule Hole watershed outlet. This highlighted the importance of solute retention and vegetation back uptake processes within the soil profile. Overall, the fire increased the mobility and export of major elements from the soils to the stream. It also shifted the vegetation-related contribution to the elemental fluxes at the watershed outlet from long-term (seasonal) to short-term (daily to monthly). (C) 2014 Elsevier B.V.

Spatial and seasonal variations in a battery of seven biomarkers were analyzed in relation to environmental parameters (temperature, salinity, and pH), physiological status (condition and gonad indexes), stress on stress (SoS), and chemical contaminant levels (heavy metals, polycyclic aromatic hydrocarbons (PAHs), and PCBs) in digestive glands. Integrated biological response (IBR) was calculated using seven biomarkers (acetylcholinesterase (AChE), benzo[a]pyrene hydroxylase (BPH), multixenobiotic resistance (MXR), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA), and metallothioneins (MT). Seasonal variations in biological response were determined during a critical period between spring and summer at two sites, where chemical contamination varies by a factor of 2 for heavy metals and a factor 2.5 for PAHs. The analysis of a battery of biomarkers was combined with the measurement of physiological parameters at both sites, in order to quantify a maximum range of metabolic regulation with a temperature increase of 11 A degrees C between May and August. According to our results, the MT, MDA, CAT, and AChE biomarkers showed the highest amplitude during the 11 A degrees C rise, while the BPH, GST, and MXR biomarkers showed the lowest amplitude. Metabolic amplitude measured with the IBR at Menzel Abdelrahmen-the most severely contaminated station-revealed the highest metabolic stress in Bizerte lagoon in August, when temperatures were highest 29.1 A degrees C. This high metabolic rate was quantified for each biomarker in the North African lagoon area and confirmed in August, when the highest IBR index values were obtained at the least contaminated site 2 (IBR = 9.6) and the most contaminated site 1 (IBR = 19.6). The combined effects of chemical contamination and increased salinity and temperatures in summer appear to induce a highest metabolic adaptation response and can therefore be used to determine thresholds of effectiveness and facilitate the interpretation of monitoring biomarkers.

Their concentrations were assessed in the liquid and solid phases (sewage particulate matter and wasted activated sludge (WAS)) by liquid chromatography-tandem mass spectrometry. The analysis of sewage from two different urban catchments connected to the WWTP showed a specific use of ofloxacin in the mixed catchment due to the presence of a hospital, and higher concentrations of sucralose in the residential area. The WWTP process removed over 90% of ibuprofen and triclosan from wastewater, while only 25% of ofloxacin was eliminated. Erythromycin, sucralose and PFOA were not removed from wastewater, the influent and effluent concentrations remaining at about 0.7 mu g/L, 3 mu g/L and 10 ng/L respectively. The behavior of PFOS and 4-nonylphenol was singular, as concentrations were higher at the WWTP outlet than at its inlet. This was probably related to the degradation of some of their precursors (such as alkylphenol ethoxylates and polyfluorinated compounds resulting in 4-NP and PFOS, respectively) during biological treatment. 4-NP, ofloxacin, triclosan and perfluorinated compounds were found adsorbed on WAS (from 5 ng/kg for PFOA to 1.0 mg/kg for triclosan). The statistical methods (principal component analysis and multiple linear regressions) were applied to examine relationships among the concentrations of micropollutants and macropollutants (COD, ammonium, turbidity) entering and leaving the WWTP. A strong relationship with ammonium indicated that some micropollutants enter wastewater via human urine. A statistical analysis of WWTP operation gave a model for estimating micropollutant output from the WWTP based on a measurement of macropollution parameters. (C) 2014 Elsevier B.V.

In response to the small, isolated nature of these forests, ideas have emerged around the re-creation of a “new European wilderness” as a nature conservation strategy. Indeed, since the end of the 19th century, traditional land use practices have been in steady decline throughout many of Europe's rural landscapes, particularly in mountainous regions and areas with poor soils and harsh climates. These very recent ecosystems have been identified as “emerging,” “novel” or “feral,” but given enough time these areas could grow into mature forests. A conservation strategy based upon letting ecosystems evolve out of human control is, as one might expect, a controversial one for Europeans. Indeed, many people enjoy the diverse and small-scale structured landscape shaped by milennia of sustainable practices by farmers, and their loss is usually seen negatively. In this essay I argue the necessity for such a re-wilding strategy and provide examples in unmanaged forests and natural successions of the Mediterranean basin, temperate Europe and floodplains with regard to the ecological benefits that they may bring to in terms of wildlife and social values. Advocating such a perspective may have broader value in diminishing the self-centred tendencies of modern societies in how they manage ecosystems.

Indeed, the thiophene ring is often considered as a structural moiety that may be involved in toxic effects in humans. We primarily focus on the genotoxic/mutagenic and carcinogenic potentials of the methyl 3-amino-4-methylthiophene-2-carboxylate (1), a precursor of the articaine local anesthetic (4) which falls within the scope of the European REACH (Registration, Evaluation, Authorisation and restriction of CHemicals) legislation. To discern some structure-toxicity relationships, we also studied two related compounds, namely the 3-amino 4-methylthiophene (2) and the 2-acetyl 4-chlorothiophene (3). Techniques employed to assess mutagenic and DNA-damaging effects involved the Salmonella mutagenicity assay (or Ames test) and the single-cell gel electrophoresis assay (or Comet assay). In the range of tested doses, none of these derivatives led to a positive response in the Ames tests and DNA damage was only observed in the Comet assay after high concentration exposure of 2. The study of their carcinogenic potential using the in vitro SHE (Syrian Hamster Embryo) cell transformation assay (CTA) highlighted the activity of compound 2. A combination of experimental data with in silico predictions of the reactivity of thiophene derivatives towards cytochrome P450 (CYP450), enabled us to hypothesize possible pathways leading to these toxicological profiles.

Organic chemicals were likely to exert acute lethal and chronic long-term effects on sensitive fish, invertebrate, or algae species in 14% and 42% of the sites, respectively. Of the 223 chemicals monitored, pesticides, tributyltin, polycyclic aromatic hydrocarbons, and brominated flame retardants were the major contributors to the chemical risk. Their presence was related to agricultural and urban areas in the upstream catchment. The risk of potential acute lethal and chronic long-term effects increased with the number of ecotoxicologically relevant chemicals analyzed at each site. As most monitoring programs considered in this study only included a subset of these chemicals, our assessment likely underestimates the actual risk.

Aquastella attenuata was specific to K. taurocephala and Aquastella acicularis was specific to P. vulgaris and P. truncatum. The occurrence of infections correlated with peak host population densities and rotifers were infected in the upper layers of the water column. Sequencing of 18S rRNA and phylogenetic analysis of both species placed them within the order Saprolegniales, in a clade closely related to Aphanomyces. The Aquastella species were morphologically distinct from other rotifer parasites as the developing sporangia penetrated out through the host body following its death to produce unique tapered outgrowths. Aquastella attenuata produced long, narrow, tapering, finger-like outgrowths, whilst A. acicularis produced shorter, spike-like outgrowths. We hypothesize that the outgrowths serve to deter predation and slow descent in the water column. Spore cleavage was intrasporangial with spore release through exit tubes. Aquastella attenuata produced primary zoospores, whereas A. acicularis released spherical primary aplanospores, more typical of other genera in the Aphanomyces clade.

Methods: This was a nationwide survey among 65 private gastroenterologists treating patients with inflammatory bowel disease in France in 2012. Results: A total of 375 inflammatory bowel disease patients were analysed: 48% had ulcerative colitis. One third of inflammatory bowel disease patients had a history of hospitalisation, and 40% of Crohn's disease patients had prior surgery. Two thirds of inflammatory bowel disease patients had active disease. Significantly fewer ulcerative colitis patients were treated with anti-tumour necrosis factor therapy than Crohn's disease patients (18.9% vs. 38.9%; p < 0.0001). Among patients treated with anti-tumour necrosis factor, only 4.5% were receiving concomitant immunomodulators. Half of inflammatory bowel disease patients had undergone a colonoscopy within the past year. For colorectal cancer screening, random biopsies and chromoendoscopy were performed in 75% and 40% of cases, respectively. An endoscopic score was used for only 10% of inflammatory bowel disease patients. About one third of inflammatory bowel disease patients had imaging studies within the past year (magnetic resonance enterography in 65%). An abdominal computed tomography scan was prescribed for 12% of inflammatory bowel disease patients. Conclusions: Many patients still have active disease in the biologics era, and the number of patients receiving combination therapy is low in private practice. Chromoendoscopy and endoscopy scores are not often used. (C) 2014 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Using the algal growth inhibition test, the green algae median Effective Concentration (EC50) values ranged from 0.341 mu M for PCB28 to more than 100 mu M for PCBs 101 and 153. Considering the MTT viability test, the abalone EC50 values ranged from 1.67 mu M for PCB153 to 89 mu M for PCB28. Our results in contrast to previous observation in vertebrates did not show significant differences between the dioxin like- and non dioxin like-PCBs toxicities regardless of the model used. However, our results demonstrated that the toxicities of PCBs were species dependent. For example, PCB28 was the most toxic compound for P. subcapitata whereas PCBs 1, 180 and 153 were less toxic for that species. On the contrary, PCB153 was reported as the most toxic for H. tuberculata haemocytes and PCB28 the least toxic. To investigate the mode of action of these compounds, we used an in silico method. Our results suggested that PCBs have a non-specific mode of action (e.g., narcosis) on green algae, and another mode of action, probably more specific than narcosis, was reported for PCBs on the abalone haemocytes.

In detritus-based headwater streams, litter accumulations constitute both a habitat and a resource for detritivorous macroinvertebrates. Because litter edibility (which promotes trophic cascades) is usually inversely correlated with its structural complexity (which weakens trophic cascades), there is a great scope for stronger trophic cascades in litter accumulations that are dominated by easily degradable litter species. However, it remains unclear how mixing contrasting litter species (conferring both habitat complexity and high quality resource) may influence top-down controls on communities and processes. In enclosures exposed in a second-order stream, we manipulated litter species composition by using two contrasting litter (alder and oak), and the presence-absence of a macroinvertebrate predator (Cordulegaster boltonii larvae), enabling it to effectively exert predation pressure, or not, on detritivores (consumptive versus non-consumptive predation effects). Leaf mass loss, detritivore biomass and community structure were mostly controlled independently by litter identity and mixing and by predator consumption. However, the strength of predator control was mediated by litter quality (stronger on alder), and to a lesser extent by litter mixing (weaker on mixed litter). Refractory litter such as oak leaves may contribute to the structural complexity of the habitat for stream macroinvertebrates, allowing the maintenance of detritivore communities even when strong predation pressure occurs. We suggest that considering the interaction between top-down and bottom-up factors is important when investigating their influence on natural communities and ecosystem processes in detritus-based ecosystems.", "publicationTitle": "OECOLOGIA", "publisher": "", "place": "", "date": "septembre 2014", "volume": "176", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "225-235", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1007/s00442-014-2990-y", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0029-8549", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Cordulegaster boltonii" }, { "tag": "Litter mixing" }, { "tag": "Shredder" }, { "tag": "Trophic cascades" }, { "tag": "litter decomposition" } ], "collections": [ "GH7VBWMX" ], "relations": {}, "dateAdded": "2014-10-23T13:06:25Z", "dateModified": "2014-10-23T13:06:25Z" } } ]
