Resumen

The determination of the positive effects of exogenous enzymes is essential to ensure their inclusion in poultry feed formulation. This study was conducted to determine the effect of enzymes on the apparent metabolisable energy (AME) value of brewers? dried grain (BDG). Xylanase, phytase and multipurpose enzymes were used in a completely randomised design to determine the effects of individual exogenous enzymes and their cocktails on poultry metabolisable energy using adult cockerels. There were eight treatments comprising a control and seven experimental treatments with BDG and one, two or three enzymes. The AME values were determined using the intubation method. Data collected were analysed using the statistical analysis system. Enzymes individually and as a cocktail improved the AME value of BDG compared to the control. An increase in the AME value was 3.48%, 5.39%, 5.92%, 14.29%, 18.13%, 23.21% and 29.58% respectively for phytase, xylanase, cocktail of xylanase and phytase, multipurpose enzyme, cocktail of multipurpose enzyme and phytase, cocktail of xylanase and multipurpose enzyme and cocktail of xylanase, phytase and multipurpose enzyme. Cocktails of enzymes were significantly better (P?0.05) than individual enzymes in their effects on apparent metabolisable energy of BDG. Phytase gave a marginal increase in AME of the studied feedstuff. It has been concluded that the cocktail of enzymes is better than individual enzymes in their effects on AME of BDG. If different enzymes are available, it is recommended that the enzyme with higher units should be used.

Resumen

Le traitement des eaux destinées à la consommation humaine (EDCH) est un vrai défi puisqu’une grande diversité de molécules contamine les eaux et ces molécules ont des propriétés qui diffèrent et qui rendent l’adaptation du traitement compliqué et très onéreux. La connaissance des contaminations a été rendue possible grâce à l’essor et à l’amélioration des techniques analytiques permettant de détecter de plus en plus de molécules présentes à de faibles concentrations. À ce jour, l’effet de ces molécules sur la santé et l’impact des potentiels effets cocktails sont toujours inconnus et peu étudiés. Dans cette étude, le couplage des techniques analytiques et biologiques (bioessais) a permis la détection d’effet sur des organismes vivants et une investigation a été menée pour trouver les molécules impliquées dans leur apparition. Ainsi, un effet fongicide très marqué a été observé sur les champignons mis en contact avec l’eau du site étudié, alors même que les analyses ciblées (recherche de plus de 850 molécules) montraient une absence de molécule. Les analyses non ciblées réalisées ont, quant à elles, montré la présence de 476 molécules dont uniquement 164 ont pu être identifiées avec une forte probabilité. Parmi ces molécules, trois fongicides ont été trouvés : l’oxadixyl, le fenpropimorphe et la fénamidone. Des études approfondies sont nécessaires pour déterminer si l’effet observé est provoqué par l’un de ces fongicides ou par une interaction synergique entre plusieurs molécules. Ces résultats appuient l’importance de préserver les zones de captages afin d’éviter de retrouver des molécules indésirables dans l’eau de consommation.

Resumen

Background Mixtures (‘cocktails’) of various analgesics are more effective in controlling post-operative pain because of potential synergetic effects. Few studies have investigated such effects in large combinations of analgesics and no studies have determined the probabilities of effectiveness. Methods We used one-hot encoding of the categorical variables reported pain levels and the administered cocktails (from a total of eight analgesics) and then applied an unsupervised neural network and then the unsupervised DBSCAN algorithm to detect clusters of cocktails. We used Bayesian statistics to classify the effectiveness of these cocktails. Results Of the 61 different cocktails administered to 750 patients, we found that four combinations of three to four analgesics were by far the most effective. All these cocktails contained Metamizole and Paracetamol; three contained Hydromorphone and two contained Diclofenac and one Diclofenac-Orphenadrine. The ML probability that these cocktails decreased pain levels ranged from 0.965 to 0.981. Choice of a most effective cocktail involves choosing the optimum in a 4-dimensional parameter space: maximum probability of efficacy, confidence interval about maximum probability, fraction of patients with increase in pain levels, relative number of patients with successful pain level decrease. Conclusions We observed that administering one analgesic or at most two is not effective. We found no statistical indicators that interactions between analgesics in the most effective cocktails decreased their effectiveness. Pairs of most effective cocktails differed by the addition of only one analgesic (Diclofenac-Orphenadrine for one pair and Hydromorphone for the other). We conclude that the listed cocktails are to be recommended.

Resumen

Some drugs candidates for treatment of Ebola virus disease (EVD), have been studied, monoclonal antibody (mAb) cocktails have shown great potential as EVD therapeutics. The advantages of mAb therapy include low toxicity, high specificity and versatility, with the range of biological effects being dependent upon the Fc region. Functions of mAbs include pathogen opsonisation, complement activation, antibody-dependent cell cytotoxicity and virus neutralization characteristics. The most known mAb cocktail, used as therapeutic, is ZMapр, manufactured by «Leaf Biopharmaceutical» from 2004. The elaborated mAb cocktails, structures and properties s of mAbs, the protective characteristics of mAbs and development of new pan-ebolavirus mAbs are reviewed in this article.

Resumen

This study was conducted to quantify the effects of enzymes and their cocktails on the apparent metabolisable energy (AME) value of palm kernel cake to maximise enzymes’ advantages. There were eight treatments, each with three replicates in a completely randomised design with T1 as control. The experimental treatments had Xylanase, Multipurpose and phytase enzymes respectively for T2, T3 and T4, and a cocktail of xylanase and multipurpose, a cocktail of xylanase and phytase, cocktail of multipurpose and phytase, and cocktail of xylanase, multipurpose and phytase for T5, T6, T7 and T8. The feeding trial was done using the intubation method. Gross energy values were determined with calorimeter while calculated AME values were subjected to analysis of variance using Statistical Analysis System and treatment means separated by Duncan Multiple Range Test. Results show that individual enzymes, apart from phytase, significantly (p>0.05) improved the AME value of palm kernel cake. Treatment T8 was significantly (p>0.05) better than the other treatments. Each cocktail was significantly better than its respective individual enzymes except cocktail of multipurpose enzyme and phytase that was not significantly different from multipurpose enzyme but significantly (p>0.05) better than phytase. It was concluded that enzymes and cocktail of enzymes could be used to enhance the energy content of nonconventional feedstuffs thereby serving as a replacement to conventional energy feedstuffs.

Resumen

The effects of soil solarization, with and without a Pseudomonas spp. cocktail or wheat rotation as alternatives to chemical control of Mesocriconema xenoplax, were investigated from 2004 to 2011. Preplant solarization and soil fumigation (67% methyl bromide + 33% chloropicrin mixture; henceforth, referred to as MBr) was initiated in 2004 in an orchard infested with M. xenoplax and a history of peach tree short life (PTSL). Plots consisted of nine treatments: (i) nonsolarized soil-alone, (ii) nonsolarized soil with bacteria cocktail (nonsolar-bacteria), (iii) nonsolarized soil with wheat (nonsolar-wheat), (iv) nonsolarized soil with bacteria cocktail and wheat (nonsolar-bacteria-wheat), (v) solarized soil-alone, (vi) solarized soil with bacteria cocktail solar-bacteria), (vii) solarized soil with wheat (solar-wheat), (viii) solarized soil with bacteria cocktail and wheat (solar-bacteria-wheat), and (ix) preplant MBr fumigation. Peach trees were planted into all plots in 2005. Nematode populations were suppressed 20 months longer after orchard establishment in solar-alone and solar-wheat plots than solar-bacteria and solar-bacteria-wheat plots. Pseudomonas spp. cocktails did not have a pronounced effect in suppressing M. xenoplax in this study. Fumigation effect on M. xenoplax population density dissipated 24 months after application. Solar-wheat-treated soil was as effective as preplant MBr fumigation in increasing tree survival from PTSL for at least 6 years after orchard establishment.

Resumen

Anesthetized preparations have been widely used to study odor-induced temporal dynamics in the olfactory bulb. Although numerous recent data of single-cell recording or imaging in the olfactory bulb have employed ketamine cocktails, their effects on networks activities are still poorly understood, and odor-induced oscillations of the local field potential have not been characterized under these anesthetics. Our study aimed at describing the impact of two ketamine cocktails on oscillations and comparing them to awake condition. Anesthesia was induced by injection of a cocktail of ketamine, an antagonist of the N-methyl-d-aspartate receptors, combined with one agonist of α2-adrenergic receptors, xylazine (low affinity) or medetomidine (high affinity). Spontaneous and odor-induced activities were examined in anesthetized and awake conditions, in the same mice chronically implanted with an electrode in the main olfactory bulb. The overall dynamic pattern of oscillations under the two ketamine cocktails resembles that of the awake state. Ongoing activity is characterized by gamma bursts (>60 Hz) locked on respiration and beta (15–40 Hz) power increases during odor stimulation. However, anesthesia decreases local field potential power and leads to a strong frequency shift of gamma oscillations from 60–90 Hz to 100–130 Hz. We conclude that similarities between oscillations in anesthetized and awake states make cocktails of ketamine with one α2-agonist suitable for the recordings of local field potential to study processing in the early stages of the olfactory system.

Resumen

Erwinia amylovora is a plant pathogen that causes fire blight on apples and pears. Bacteriophages, which are viruses that selectively infect specific species of bacteria and are harmless to animal cells, have been considered as biological control agents for the prevention of bacterial pathogens. In this study, we aimed to use bacteriophages that infect E. amylovora as biocontrol agents against fire blight. We isolated bacteriophages Fifi044 and Fifi318 infecting E. amylovora, and characterized their morphology, plaque form, and genetic diversity to use as cocktails for disease control. The stabilities of the two phages were investigated at various temperatures and pH values and under sunlight, and long-term storage experiment was conducted for a year. To evaluate whether the two phages were suitable for use in cocktail form, growth curves of E. amylovora were prepared after treating the bacterial cells with single phages and a phage cocktail. In addition, a disease control test was conducted using immature apples and in vitro cultured apple plantlets to determine the biocontrol effects of the phage cocktail. The two phages were morphologically and genetically different, and highly stable up to 50°C and pH value from 4 to 10. The phages showed synergistic effect when used as a cocktail in the inhibition of host bacterial growth and the disease control. This study demonstrated that the potential of the phage cocktail as a biocontrol agent for commercial use.

Resumen

Abstract Background Multidrug-resistant (MDR) Pseudomonas aeruginosa infections are increasing in prevalence and cause significant mortality. The MexAB-OprM efflux system confers resistance to a wide range of drugs, including β-lactams, fluoroquinolones, tetracyclines, and macrolides. Obligately lytic bacteriophages (phages) are viruses that infect and kill bacteria. Phage therapy has been suggested as an alternative treatment option in combination with traditional antibiotics. The objective of this study was to determine the ability of a phage cocktail in combination with ciprofloxacin (CIP) to improve bacterial killing and/or prevent the emergence of phage resistance in MDR P. aeruginosa. Methods Initial bacterial susceptibility to phage was evaluated with three newly isolated phages (phages EM, LL, and A6) against ten clinical MDR P. aeruginosa isolates. Theoretical multiplicity of infection (tMOI) optimization was performed with two phages with the broadest initial susceptibility (tMOI: 1.0 chosen for further analysis). A preliminary evaluation was performed with P. aeruginosa R9316 (carbapenem-resistant clinical strain with MexAB-OprM overexpression, as determined previously by quantitative real-time PCR). Synergy for phage cocktail combinations (≥ 2-log10 CFU/mL kill compared to most effective single agent at 24 h), bactericidal activity for all samples (≥ 3-log10 CFU/mL reduction at 24 h compared to starting inoculum), and phage resistance development were evaluated in time kill analyses (TKA). Results R9316 is a MDR P. aeruginosa isolate with a CIP MIC of 2 mg/L. Phage cocktails as monotherapy had little impact on bacterial eradication (reduction: 1.19 log10 CFU/mL). However, the addition of CIP to phage cocktails of EM and LL phages led to synergistic and bactericidal effects (reduction: 3.92 log10 CFU/mL). Furthermore, phage resistance was observed in the phage monotherapy regimens. Whereas the addition of CIP was shown to prevent the emergence of phage resistance in some regimens. Conclusion Our results show synergistic activity and prevention of phage resistance with phage cocktail-antibiotic combinations against MDR P. aeruginosa. Further research is needed to determine the impact of phage cocktail therapy on additional strains and clinical outcomes. Disclosures Michael J.

Resumen

To investigate the effects of sublethal stress on Salmonella thermal inactivation kinetics, an eight-strain Salmonella cocktail was subjected to heat shock (30 min at 54°C), cold shock (2 h at 4°C), and starvation stress (10 days in phosphate buffer at 4°C), harvested by centrifugation, and inoculated into irradiated comminuted turkey. Immediately after stressing, the Salmonella cocktails contained 89.1% heat-injured, 44.7% cold-injured, and 67.7% starvation-injured cells, as determined by plating on selective and nonselective media. D60°C-values for the heat-shocked cocktail (0.64 min on Trypticase soy agar containing 0.6% yeast extract [TSAYE], 0.35 min on xylose lysine desoxycholate [XLD] agar) were higher (P < 0.05) than those for the unshocked control (0.41 min on TSAYE, 0.17 min on XLD), whereas D60°C-values for the cold-shocked cocktail (0.38 min on TSAYE, 0.17 min on XLD) were not significantly different from those for the control. Starved cells had the same D60°C-value on TSAYE as did the unshocked cocktail, but the D60°C-value on XLD was significantly lower (0.14 min). Although starvation and cold shock were not thermally protective, heat shock increased thermal resistance, indicating that product history and the physiological state of the Salmonella cells should be considered when developing and validating thermal processes. D60°C-values observed on selective media were significantly lower than those observed on nonselective media for all stress treatments and for the control. Therefore, nonselective culture media should be used to assess the response of microorganisms to a thermal challenge when developing performance standards for lethality.

Resumen

Les changements climatiques et l'émission de polluants dans l'environnement sont susceptibles d'entrainer des effets croisés sur les communautés et le fonctionnement des écosystèmes. Les changements de température sont notamment susceptibles de modifier le comportement et la toxicité des polluants, et de sensibiliser les organismes aux stress chimiques. Inversement, l'exposition à des polluants peut diminuer la tolérance thermique des espèces ectothermes comme les poissons. Dans ce contexte, nous avons étudié la réponse d'une espèce modèle de poissons en toxicologie aquatique, le Carassin doré (Carassius auratus), soumis à des stress chimique et thermique individuels et combinés. Pour cela, le carassin doré a été exposé à un cocktail d'herbicides et de fongicides à des concentrations réalistes d'un point de vue environnemental à deux températures pendant 96h ou 16 jours. Les réponses ont été observées de l'échelle moléculaire à l'échelle individuelle par des approches omiques (protéomique et métabolomique), biochimiques (cortisol, biomarqueurs de stress oxydant et allocation cellulaire énergétique), indicielles (indices somatiques et de condition) et comportementales (remaniement sédimentaire, activité, exploration et comportement alimentaire). Les résultats montrent que l'exposition des poissons aux stress chimique et thermique individuels entraine une réponse générale de stress impliquant des compensations biochimiques, énergétiques, physiologiques et comportementales. L'absence d'effets sur la santé générale des carassins suggère la mise en place d'une réponse de stress efficace et adaptée, bien que l'hypoactivité observée chez les poissons exposés aux cocktails de pesticides soit susceptible d'entrainer une diminution de leurs performances et de leur fitness. A l'inverse, les carassins exposés aux stress chimique et thermique combinés montrent une inhibition de la réponse générale de stress, avec des effets antagonistes sur la sécrétion de cortisol, l'induction de certains systèmes de défense antioxydants et la compensation énergétique. Des effets plus importants sont en revanche observés au niveau comportemental ainsi qu'une diminution significative de la condition générale des poissons. Ces résultats montrent que l'augmentation de la température sensibilise les poissons à la contamination de l'eau par les pesticides. L'inhibition de la réponse de stress chez des poissons exposés à des mélanges complexes de pesticides dans un écosystème soumis à de multiples contraintes pose de nombreuses questions pour la conservation des espèces dans l'environnement
Crossed-effects between climate change and chemical pollutions were identified on community structure and ecosystem functioning. Temperature rising affect the toxic properties of pollutants and the sensitiveness of organisms to chemicals stress. Inversely, chemical exposure may decrease the thermal tolerance of ectothermic species, as fish. In this context, we studied the response of a biological model in aquatic toxicology, the goldfish (Carassius auratus), to individual and combined chemical and thermal stresses. In this aim, we exposed the goldfish to environmental relevant concentrations of herbicide and fungicide mixtures at two temperatures for 96 hours or 16 days. The fish responses were assessed from the molecular level to individual endpoints, including omic approaches (proteomic and metabolomic), biochemical analyses (cortisol, antioxidant defenses, cellular energy allocation), indexes (somatic and condition factors) and behavioral assays (sediment reworking, activity, exploration and feeding). Our results showed that individual chemical or thermal stresses induced a general stress response including biochemical, metabolic, physiological and behavioral compensations. The absence of deleterious effect on the global condition of fish suggested the implementation of an efficient and adaptive stress response, while the hypoactivity of fish exposed to pesticide mixtures could entrain a decreased performance and fitness into the wild. At the opposite, the combined chemical and thermal stresses induced reciprocal inactivation of the stress response, with antagonism effect on cortisol secretion, antioxidant defense induction and metabolic compensation. However, increased effect on behavioral traits and decreased global condition of fish were observed. Our study showed that temperature rising sensitized fish to pesticide exposure. Finally, inhibited stress response in fish exposed to pesticide cocktails raises concerns about species conservation an ecosystem under multiple pressures

Resumen

Depuis plusieurs décennies, le déclin des oiseaux spécialistes des milieux agricoles anime le monde scientifique à travers une large documentation sur les causes et les conséquences de ce phénomène. Une des questions clefs porte sur la part de responsabilité des pesticides dans cette tendance, car les études menées jusqu’ici indiquent des relations de cause à effet sans pour autant identifier clairement les mécanismes sous-jacents. L'un des défis majeurs est donc de fournir des faits pertinents sur le plan biologique pour une meilleure évaluation des risques liés aux pesticides pour les oiseaux des champs. Ainsi, le but de cette thèse était d’appréhender les effet sublétaux des pesticides sur les traits d’histoire de vie de la perdrix grise (Perdix perdix) à la fois à l’aide d’expérimentations en conditions contrôlées mais aussi de suivi d’individus sauvages. Associée à la survie et à la reproduction, l’approche multi-trait réalisée ici a permis d’appréhender (1) les effets négatifs des pesticides sur plusieurs traits d’histoire de vie des perdrix, à la fois en captivité mais aussi in natura, (2) l’omniprésence de cocktails de pesticides dans le sang des oiseaux et leurs liens avec les effets sublétaux, (3) l’importance de prendre en compte les processus évolutifs dans les effets à long terme des pesticides en considérant les effets parentaux et la plasticité phénotypique des individus et enfin (4) la nécessité d’utiliser le biomonitoring des espèces sentinelles pour un meilleur suivi de la contamination des agroécosystèmes à l’échelle locale mais aussi comme outil de développement et de mise en place de zones refuges à l’exposition aux pesticides
For several decades, the farmland bird decline has been the subject of much scientific attention, with a large body of literature on the causes and consequences of this phenomenon. One of the major issue is whether pesticides are responsible for this trend, as studies conducted so far indicate cause and effect relationships without clearly identifying the underlying mechanisms. A major challenge is thus to provide biologically relevant evidences for a better assessment of pesticide-related risks to farmland birds. The aim of this thesis was to study the sublethal effects of pesticides on the life history traits of the grey partridge (Perdix perdix) using both experiments under controlled conditions and monitoring of free-living birds. In combination with survival and reproduction, the multi-trait approach carried out here allowed us to understand (1) the deleterious effects of pesticides on several life history traits of partridges, both in captivity and in natura, (2) the ubiquity of pesticide cocktails in the blood of birds and their links with sublethal effects, (3) the importance of considering evolutionary processes in the long-term effects of pesticides by considering parental effects and phenotypic plasticity of individuals and finally (4) the need to use biomonitoring of sentinel species for a better monitoring of the contamination of agroecosystems at the local scale but also as a tool for the development and implementation of refuge areas to pesticide exposure

Resumen

Les micropolluants, dont les pesticides et les résidus pharmaceutiques, constituent une menace pour les écosystèmes aquatiques. Dans ces écosystèmes, les micropolluants rencontrent l'interface sédiment-eau (SWI), une zone biogéochimiquement active pour leur dissipation. Cette thèse examine les facteurs environnementaux impliqués dans la dégradation des micropolluants emblématiques, tels que le (S)-métolachlore (herbicide agricole), le terbutryn (biocide urbain) et la metformine (médicament antidiabétique), dans des microcosmes de laboratoire mimant l'interface eau-sédiment. Elle explore comment les communautés procaryotes répondent à l'exposition à des mélanges de micropolluants, à des événements de contamination successifs et à des conditions variables d'oxygène. La metformine et le métolachlore se sont dissipés, tandis que la terbutryne persiste. La metformine se dégrade aussi en anoxie. L'analyse de séquence des amplicons du gène 16S ARNr a mis en évidence des réponses distinctes des communautés microbiennes dans les expériences avec des micropolluants individuels ou en mélanges, ainsi qu'un effet combiné de l'exposition à la metformine et des alternances des conditions d'oxygène. Un nouveau modèle a mis en évidence des effets non additifs, antagonistes et synergiques des micropolluants sur des taxons spécifiques. Enfin, des expériences exploratoires de marquage isotopique stable avec du glucose 13C et de la metformine 13C2-méthylée permettent d’identifier les procaryotes assimilant potentiellement la metformine-diméthylamine. Cette thèse fournit un cadre pour l’étude des dynamiques régissant le comportement des micropolluants et souligne la diversité des interactions potentielles entre les micropolluants, les communautés procaryotes et les facteurs environnementaux dans l'étude de l'interface eau-sédiment multi-contaminée
Micropollutants, including pesticides and pharmaceuticals, pose a growing threat to aquatic ecosystems. In aquatic ecosystems, micropollutants encounter the sediment-water interface (SWI), a crucial biogeochemical hotspot for their dissipation. This PhD thesis examines the effects of environmental factors on the degradation of emblematic micropollutants, such as (S)-metolachlor (agricultural herbicide), terbutryn (urban biocide) and metformin (antidiabetic drug) in laboratory microcosms mimicking the sediment-water interface. Additionally, it explores how prokaryotic communities respond to exposure to micropollutant mixtures, successive contamination events, and varying oxygen conditions. Dissipation of metformin and metolachlor occurred while terbutryn persisted. Metformin dissipation also occurred under anoxic conditions. Sequence analysis of 16S rRNA gene amplicons evidenced distinct responses of prokaryotic communities in experiments with individual micropollutant or mixtures thereof, and a combined effect of metformin exposure and alternances of oxygen conditions. A newly developed model highlighted non-additive antagonistic and synergistic effects of micropollutants on specific taxa across taxonomic levels. Finally, exploratory Stable Isotope Probing experiments with 13C-glucose and methyl-labelled 13C2-metformin were designed to identify potential metformin-dimethylamine assimilating prokaryotes. Altogether, this thesis provides a framework to investigate dynamics governing the behaviour of micropollutant mixtures and underscores the diversity of potential interactions between micropollutants, prokaryotic communities, and environmental factors in the study of multi-contaminated SWI

Le glyphosate, l’atrazine, et leurs principaux produits de dégradation (la déséthyl-atrazine ou DEA, et l’amino methyl phosphoric acid ou AMPA) sont parmi les pesticides les plus utilisés dans le monde et en France. Ils sont retrouvés en grande quantité dans plusieurs matrices environnementales dans les denrées alimentaires et les eaux de boisson.L’objectif de notre travail a été d’évaluer le potentiel génotoxique et mutagène in vitro et in vivo de ces quatre pesticides seuls et en mélanges, puis d’étudier les effets protecteurs d’un mélange d’extrait de plantes anti-mutagènes (Berberis vulgaris, Arctium lappa et Taraxacum officinalis) (DIG) sur la génotoxicité du mélange des quatre pesticides.Les résultats de notre étude in vitro ont montré que le potentiel génotoxique des pesticides dépend de leur environnement physico-chimique, et que les mélanges de pesticides peuvent révéler des propriétés génotoxiques bien plus importantes que celles prévisibles lors de l’exposition aux molécules individuelles avec survenue d’un effet cocktail. Les résultats de notre étude in vivo ont établi la puissante activité génotoxique et mutagène du mélange composé de quatre pesticides. Ils ont mis en évidence les effets cocktails qui peuvent se produire dans les mélanges de pesticides soulignant les limites des stratégies toxicologiques habituelles. Nous avons montré que les cellules cérébrales sont la principale cible des pesticides, probablement en rapport avec une importante sensibilité au stress oxydatif. Dans une troisième partie, nous avons démontré les effets protecteurs de DIG sur la génotoxicité/mutagénicité du mélange des quatre pesticides
Glyphosate, atrazine, and their main degradation products (desethyl-atrazine or DEA, and the amino methyl phosphoric acid or AMPA) are among the most widely used pesticides in the world and in France. They are found in large quantities in several environmental matrices but also in food and drinking water.The aim of our work was to evaluate the genotoxicity and mutagenicity in vitro and in vivo of these four pesticides, alone and in mixtures, and to study the protective effects of a mixture composed with extracts of anti-mutagenic plants (Berberis vulgaris, Arctium lappa and Taraxacum officinalis) (DIG) on the genotoxicity of the mixture of four pesticides.The results of our in vitro study showed that the genotoxic potential of pesticides depends on their physico-chemical environment, and that mixtures of pesticides can reveal genotoxic properties more important than those predictable during the exposure to individual molecules, with occurrence of a cocktail effect. The results of our in vivo study clearly established the powerful genotoxic and mutagenic activity of the mixture of four pesticides. They highlighted the cocktail effects that may occur in mixtures of pesticides, underlining the limits of conventional toxicological strategies based on an individual assessment of the molecules. We have shown that brain cells are the main target of pesticides, probably related to a significant sensitivity to oxidative stress. In the third part, we demonstrated the protective effects of DIG on the genotoxicity and mutagenicity of the mixture of four pesticides

Resumen

Ce travail de thèse a pour objectif d'étudier le comportement de produits pharmaceutiques dans l’environnement aux interfaces sédiment/sol-eau afin de mieux comprendre les processus mis en jeu suite à leur rejet, leur devenir et leur impact. Ainsi la rétention de quatre produits pharmaceutiques a été étudiée sur différents solides (sol/sédiment). La capacité d’échange cationique a été identifiée comme le paramètre prépondérant gouvernant la rétention du propranolol, le pH gouvernant celle du sotalol. Dans le cas des mélanges de contaminants, une compétition pour les sites de surface a pu être mise en évidence avec notamment une diminution de l’adsorption du sotalol et du furosémide. L’influence du cuivre, métal ubiquiste dans l’environnement, sur la rétention des produits pharmaceutiques a également été étudiée. Si celui-ci n’a pas eu d’influence sur la rétention du propranolol, du sotalol et du furosémide, il a par contre augmenté la mobilité du sulfaméthoxazole dans l’environnement en diminuant son adsorption. Enfin, il a été montré que la présence de ces polluants dans l’environnement induit des effets toxiques sur des organismes aquatiques
This thesis aims at studying the behaviour of pharmaceuticals in the environment at sediment/soil-water interfaces in order to better understand the involved processes following their release, their fate and their impact. Thus, the retention of four pharmaceuticals was investigated on different solids (soil/sediment). The cation exchange capacity has been identified as the parameter governing the propranolol retention and the pH value governing sotalol adsorption. In the case of contaminant mixtures, a competition for the surface sites was evidenced with in particular a decrease of sotalol and furosemide adsorption.The influence of copper, a ubiquitous metal in the environment, on pharmaceutical retention was also studied. Although copper did not influence the retention of propranolol, sotalol and furosemide, its presence increased the mobility of sulfamethoxazole in the environment by decreasing its adsorption. Finally, it has been shown that the presence of these pollutants in the environment induced toxic effects on aquatic organisms

Resumen

"American cranberry (Vacciniumm macrocarpon) has been long known for its benefits in maintaining urinary tract health. Clinical trials have shown that drinking cranberry juice can prevent urinary tract infections (UTIs) in various subpopulations that are prone to UTIs, especially women, but the mechanisms by which cranberry acts against uropathogenic bacteria are still unclear. Studies showed that when exposed to cranberry juice or A- PACs, a group of tannins that are unique to cranberry, the adhesion activity and biofilm formation of uropathogenic bacteria were reduced. However, the metabolism of cranberry juice has not be elucidated, therefore further study is needed to find out whether the anti-bacterial components in cranberry could survive the digestive system and reach the urinary tract, and how the components or metabolites remaining in urine act against uropathogenic bacteria. We used atomic force microscopy (AFM) to study the surface adhesion force of uropathogenic E. coli incubated with urine samples that were collected from volunteers after drinking 16 oz. of cranberry juice cocktail (CJC) or water. The urine samples were collected at 0, 2, 4, 6, and 8 hours after CJC or water consumption. When incubated with post-water urine, the adhesion forces of pathogenic bacteria that have fimbriae (E. coli B37, B73, B78, BF1023, CFT 073, and J96) did not change; whereas the adhesion forces of these strains decreased over the 8 hour period after CJC consumption. The control strain that does not have frimbriae, E. coli HB101, showed low adhesion force when incubated with post-water and post-CJC urine. In a human red blood cell agglutination (HRBC) assay, the attachment of pathogenic E. coli to red blood cells was significantly lower after exposed to post-CJC urine, compared to those exposed to post-water urine. These results indicate the anti-bacteria components or metabolites of CJC stay active in urine, and these compounds prevent adhesion of E. coli by reducing fimbriae-mediated adhesion. We also examined the effects of drinking CJC on biofilm formation of uropathogenic bacteria. Female volunteers were given 16 oz. of CJC or placebo, and their urine was collected at 0, 2, 8, 24, and 48 hours after consumption. Bacteria (E. coli B37, CFT073, BF1023, HB101, and S. aureus ATCC43866) were cultured in a mixture of urine and growth media in 96 well microtiters. The biofilm formed was quantified by staining the biofilm dissolved in a solvent with crystal violet and measuring the absorbance at 600 nm. The results showed that biofilm formation was reduced within 24 hours after CJC consumption, and it started to increase after 48 hours, possibly due to the washout of CJC in the system. These studies suggest that CJC can be an effective preventive measure for UTIs as it inhibits adhesion and biofilm formation of uropathogenic bacteria."

Resumen

Les données scientifiques actuelles suggèrent un déclin de la diversité et de l’abondance des insectes, y compris les abeilles domestiques Apis mellifera. Ces dernières sont confrontées à de fortes pertes de colonies dans plusieurs régions du monde telles que l’ouest de l’Europe et les États-Unis. De nombreuses études suggèrent que l’origine du déclin des colonies d’abeilles est multicausale et identifient les pesticides et les agents pathogènes comme étant les principaux contributeurs à ce déclin. La co-exposition des abeilles à de multiples pesticides et l’infection par plusieurs pathogènes constituent un phénomène courant. Cependant, les recherches sur les effets des mélanges de pesticides n’ont pas fait l’objet d’un intense développement. Ainsi, les travaux conduits dans le cadre de cette thèse ont été focalisés sur la détermination de la toxicité des mélanges de pesticides, appliqués à des niveaux d’exposition environnementaux, en présence d’un agent pathogène. Le choix s’est porté sur l’étude des interactions entre un insecticide néonicotinoïde, l’imidaclopride, un fongicide azole, le difénoconazole, et un herbicide, le glyphosate, en présence de l’agent pathogène Nosema ceranae. Les résultats des différentes études effectuées durant cette thèse, révèlent la complexité des études sur les mélanges de pesticides. Ces travaux nous ont permis de constater que les effets d’un mélange de pesticides peuvent fortement varier en fonction des concentrations des pesticides constituant le mélange. L’augmentation du nombre de substances et du niveau d’exposition, n’induit pas nécessairement une augmentation de la toxicité du mélange. De plus, les effets du mélange peuvent varier en fonction de la séquence d’exposition aux pesticides et de l’état sanitaire des abeilles. Les mélanges de pesticides affectent l’état physiologique des abeilles suite à une réponse systémique liée à des perturbations de mécanisme généraux tels que le stress oxydant. Cependant, ces trois pesticides, seuls et en mélanges n’ont aucun effet sur l’installation du microbiote intestinal à des niveaux d’exposition environnementaux
Current scientific findings suggest a decline in the diversity and abundance of insects, including the honey bee Apis mellifera. The latter are facing high colony losses in several regions of the world such as Western Europe and the United States. Numerous studies suggest that the origin of bee colony decline is multi-causal and identify pesticides and pathogens as the main contributors to this decline. Co-exposure of honey bees to multiple pesticides and infection by multiple pathogens are common phenomena. However, research on the effects of pesticide mixtures has not been extensively developed. Thus, the thesis work has focused on determining the toxicity of pesticide mixtures, applied at environmental exposure levels, in the presence of pathogens. The choice was made to study the interactions between a neonicotinoid insecticide, imidacloprid, an azole fungicide, difenoconazole, and a herbicide, glyphosate, in the presence of the pathogen Nosema ceranae. The results of the different studies, carried out during this thesis, reveal the complexity of the studies on pesticide mixtures. The work allowed us to notice that the effects of a pesticide mixture can vary according to the concentrations of the pesticides constituting the mixture. The increase of the number of substances and the level of exposure does not necessarily induce an increase of the toxicity of the mixture. Furthermore, the effects of the mixture may vary depending on the sequence of exposure to the different pesticides and the health status of the honey bees. Pesticide mixtures affect the physiological state of individuals as a result of a systemic response related to disturbances of general mechanisms such as oxidative stress. However, these three pesticides, alone and in mixtures, have no effect on the installation of the intestinal microbiota at environmental exposure levels

Resumen

This book describes and explains the failure of the federal courts of the United States to act and to provide remedies to individuals whose constitutional rights have been violated by illegal state coercion and violence. This remedial vacuum must be understood in light of the original design and historical development of the federal courts. At its conception, the federal judiciary was assumed to be independent thanks to an apolitical appointment process, a limited supply of adequately trained lawyers (which would prevent cherry-picking judges), and the constraining effect of laws and constitutional provision. Each of these checks failed. A first consequence was that the early federal judicial system was highly dependent on Congress. Not until the last quarter of the nineteenth century did a robust federal judiciary start to emerge. And it was only in the first quarter of the twentieth century that the federal courts took something like their present form. The book then charts how pressure from Congress and the White House has continued to shape courts’ behavior—first eliciting a mid-twentieth-century explosion in individual remedies, and then driving a five-decade-long collapse. Judges themselves have not avidly resisted this decline, in part because of ideological reasons and in part out of institutional worries about a ballooning docket. Today, as a result of these trends, the courts are stingy with individual remedies, but aggressively enforce the so-called structural constitution of the separation of powers and federalism. This cocktail has highly regressive effects. It is in clear need of reform.

Resumen

This book rights the widespread myth that Romania was a reluctant member of the Axis during World War II. In correcting this fallacy, the book shows that, of an estimated 300,000 Jews who perished in Romania and Romanian-occupied Ukraine, more than 64,000 were, in fact, killed by Romanian soldiers. Moreover, the Romanian Army conducted a brutal campaign in German-occupied Ukraine, resulting in the deaths of thousands of Soviet prisoners of war, partisans, and civilians. Investigating why Romanian soldiers fought and committed such atrocities, the book argues that strong ideology—a cocktail of nationalism, religion, antisemitism, and anticommunism—undergirded their motivation. The book integrates the Holocaust into the narrative of military operations to show that most soldiers fully supported the wartime dictator, General Ion Antonescu, and his regime’s holy war against “Judeo-Bolshevism.” The army perpetrated mass reprisals, targeting Jews in liberated Romanian territory; supported the deportation and concentration of Jews in camps or ghettos in Romanian-occupied Soviet territory; and played a key supporting role in S.S. efforts to exterminate Jews in German-occupied Soviet territory. The book proves that Romania became Nazi Germany’s most important ally in the war against the U.S.S.R. because its soldiers were highly motivated, thus overturning much of what we thought we knew about this theater of war. The book provides the first complete history of why Romanian soldiers fought on the Eastern Front.

Resumen

Abstract In critically ill patients with circulatory shock, rapid identification of hemodynamic derangements and targeted therapy to reverse underlying pathophysiology are required. Current guideline recommendations often suggest first- and second-line choices for vasopressor and inotropic therapy. However, each vasoactive medication has a therapeutic profile that can benefit but can also potentially harm a patient based on their underlying pathophysiology and comorbidities. It is important for the clinician to be prepared to choose alternative therapies if first-line medications are unavailable or lead to undesirable effects. Balancing the effects of inotropy and vasomotor tone through combinations of medications is necessary when multiple shock states are present (vasodilatory, hemorrhagic/ hypovolemic, LV vs. RV cardiogenic shock).

Resumen

Although herbicides are designed to remove or control weeds, pollution of water ecosystems with herbicides could have adverse effects on aquatic animals such as fish. The effect of herbicides on nontarget organisms may be different than expected, as herbicides may interact with another environmental contaminant. Since there are different contaminants in the water, fish may live in the cocktail of xenobiotics, including herbicides. Therefore, herbicides alone and in combination with other pollutants could affect fish physiology. Thus, the interaction of environmental contaminants with pesticides may create a situation in which a chemical affects the activity of a pesticide; that is, its effects increase or decrease or produce a new effect that neither of them creates on its own. These interactions may occur due to accidental misuse or lack of knowledge about the active ingredients in the relevant materials. This study aimed to review the effects of herbicides alone and in combination with other xenobiotics on various aspects of fish biology. In this study, different biomarkers were reviewed in fish exposed to herbicides.

Resumen

Pesticides used prophylactically in intensive farming negatively affect non-target organisms, contributing to the acceleration of species extinction. This chapter considers key issues of pesticide toxicity that harm biodiversity and the natural world, including the adjuvant problem and the cocktail effect. The chapter examines these issues and the pesticide authorisation process, and asks whether these mechanisms provide the protection necessary for wildlife, the soil and the wider natural environment. The case study explores the effect of pesticide use on endangered hedgehog.

Resumen

Abstract Birds are hosts of an incredibly variable cocktail of microparasites. In terms of the combined effect of the infections on the individual (let alone at the population level), we recognize very little of what is going on. Indeed, most of our information is based on single pathogenic (i.e. disease producing) infections of domesticated avian species. This represents knowledge accumulated over a few thousand years at most, barely a fraction of the more than 100 000 000 years in which microparasites have been associated with birds.

Texto completo

Resumen

Using a sample of 32 developed and developing countries we analyze the empirical characteristics of Sudden Stops in capital flows and the relevance of balance-sheet effects in the likelihood of their occurrence. We find that large real exchange rate (RER) fluctuations accompanied by Sudden Stops are basically an emerging market (EM) phenomenon. Sudden Stops seem to come in bunches, grouping together countries that are different in many respects. However, countries are similar in that they remain vulnerable to large RER fluctuations. This may be the case because countries are forced to make large adjustments in the absorption of tradable goods, and/or because the size of dollar liabilities in the banking system (i.e., domestic liability dollarization, or DLD) is large. Openness, understood as a large supply of tradable goods that reduces leverage over the current account deficit, in combination with DLD, is a key determinant of the probability of Sudden Stops. The relationship between Openness and DLD in the determination of the probability of Sudden Stops is highly non-linear, implying that the interaction of high current account leverage and high dollarization may be a dangerous cocktail.
