Study of common database feeding with results coming from different analytical methods in the framework of illicit drugs chemical profiling

Analytical results harmonisation is investigated in this study to provide an alternative to the restrictive approach of analytical methods harmonisation which is recommended nowadays for making possible the exchange of information and then for supporting the fight against illicit drugs trafficking. Indeed, the main goal of this study is to demonstrate that a common database can be fed by a range of different analytical methods, whatever the differences in levels of analytical parameters between these latter ones. For this purpose, a methodology making possible the estimation and even the optimisation of results similarity coming from different analytical methods was then developed. In particular, the possibility to introduce chemical profiles obtained with Fast GC-FID in a GC-MS database is studied in this paper. By the use of the methodology, the similarity of results coming from different analytical methods can be objectively assessed and the utility in practice of database sharing by these methods can be evaluated, depending on profiling purposes (evidential vs. operational perspective tool). This methodology can be regarded as a relevant approach for database feeding by different analytical methods and puts in doubt the necessity to analyse all illicit drugs seizures in one single laboratory or to implement analytical methods harmonisation in each participating laboratory.

Marco metodológico para la definición de un perfil profesional en educación superior = Methodological framework for the definition of a professional profile in higher education

En el marco del Espacio Europeo de Educación Superior 1 se inscriben innumerables acciones que están desarrollando todas las universidades europeas con la intención de llegar al 2010 con un bagaje lo suficientemente importante como para afrontar este cambio con entereza y sobretodo conservando (o incrementando) la calidad de los procesos de enseñanza- aprendizaje que hasta el momento han predominado. Dentro de este amplio proceso de transformación se encuentra el diseño de los nuevos Grados que brinda la oportunidad de replantear los planes de estudios, por tanto, la organización de las asignaturas, estructura de los contenidos, metodologías y sistemas de evaluación. Toda esta reflexión debe girar, a nuestro entender, alrededor de tres núcleos que se encuentran en estado deinterdependencia: los escenarios profesionales, los perfiles profesionales y las competencias que en ellos se inscriben.Para poder plantear los nuevos Grados en coherencia con la era del EEES debe hacerse un análisis minucioso de los perfil profesionales demandados por el mercado de trabajo que, al fin y al cabo será el destino de los profesionales que se forman en nuestras universidades, es por ello, que la tarea de definir el perfil profesional a priori del diseño de los nuevos Grados resulta una máxima para garantizar la calidad de estos. En este trabajo se presenta un ejemplo de metodología a seguir para la definición de un perfil profesional en Educación Superior, concretamente, el del Ingeniero TIC mediante el Análisis Funcional.

Sensing, uptake and response to c4-dicarboxylic acids in pseudomonas aeruginosa pao1

C4-dicarboxylates are one of the preferred carbon and energy sources for the growth of P. aeruginosa, a ubiquitous and metabolically versatile bacterium. However, despite their importance, C4-dicarboxylates sensing and uptake systems were poorly understood in P. aeruginosa and only little information was available in the literature. In our work, the C4-dicarboxylate transport (Dct) system in P. aeruginosa was found to be composed of a novel two-component system, called DctB/DctD, regulating together with the sigma factor RpoN the expression of two newly identified C4-dicarboxylate transporters: DctA and DctPQM. Inactivation of the dct A, dctB or dctD gene caused a growth defect of the strain in minimal media supplemented with succinate, fumarate or malate, indicating their major role in Dct. However, residual growth of the dctA mutant in these media suggested the presence of redundant C4-dicarboxylate transporter(s). Tn5 insertion mutagenesis of the kdctA mutant, combined with a screening for growth on succinate, led to the identification of a second Dct system, the DctPQM transporter, belonging to the tripartite ATP-independent periplasmic (TRAP) family of carriers. AdctAAdctPQM double mutant showed no growth on malate and fumarate albeit residual growth on succinate suggested that additional transporters for succinate are present. Competition experiments demonstrated that the DctPQM carrier was more efficient than the DctA carrier for the utilization of succinate at μΜ concentrations, whereas DctA was the major transporter at mM concentrations. For the first time, high- and low-affinity uptake systems for succinate (DctA and DctPQM) are reported to function co-ordinately to transport C4- dicarboxylates. Most probably, the presence of redundant uptake systems contributes to the versatility of this bacterium. Next, the regulation of the Dct system was investigated. While performing a parallel study about the carbon catabolite repression (CCR) phenomenon in P. aeruginosa, a link between the CCR cascade (CbrAB/CrcZ/Crc) and the Dct system was observed. Crc is a translational repressor acting when preferred carbon sources (like C4-dicarboxylates) are present. CrcZ is a small RNA acting as a functional antagonist of Crc and induced by the CbrA/CbrB two-component system when non preferred carbon sources (like mannitol) are utilized. Novel targets of the CbrAB/CrcZ/Crc system in P. aeruginosa were identified using transcriptome analysis; among them dctA and dctPQM were detected. CCR is regulating the dct transporter genes expression depending on the succinate concentrations in the medium of growth; this modulation of CCR is possible because, at the same time, succinate concentrations tune CCR. In a medium containing high succinate concentrations, CrcZ levels were low and therefore Crc inhibited the translation of mRNA targets. Whereas in a medium containing low succinate concentrations, the subsequent increase of CrcZ levels sequestered Crc, inhibiting its activity. This model shows for the first time that CCR possesses a feedback-based circuitry, a very important type of regulatory loop that confers the best adaptive response under changing environmental conditions. The expression of the dct transporter genes is also found to be regulated by the RNA chaperone protein Hfq. Hfq has the same post-transcriptional effect than Crc at high concentration of succinate, i.e. inhibiting dctP and dctR and indirectly favouring dctA expression. Moreover, an additional indirect positive regulation of dctP expression by Hfq was found. Finally, a metabolome approach was performed to investigate the internal signals modulating CCR via induction of CbrA activity in P. aeruginosa PAOl and P. putida KT2442. The results of the analysis are currently under study in the laboratory. - Les acides C4-dicarboxyliques font partie des sources de carbone et d'énergie préférés de P. aeruginosa, une bactérie versatile et ubiquitaire. Néanmoins, malgré leur importance, comment la présence des acides C4-dicarboxyliques dans le milieu est sentie par la bactérie et comment ils sont transportés dans la cellule chez P. aeruginosa n'étaient pas connus. De plus, peu d'informations sur ces procédés ont été répertoriées dans la littérature. Grace à notre travail, le système de transport des acides C4-dicarboxyliques (Dct) chez P. aeruginosa a pu être caractérisé. En effet, il est composé d'un nouveau système à deux composants, nommé DctB/DctD, qui régule, en combinaison avec le facteur sigma alternatif RpoN, l'expression des deux nouveaux transporteurs des acides C4-dicarboxyliques: DctA et DctPQM. L'inactivation des gènes dctA, dctB or dctD cause un défaut de croissance des souches mutantes dans un milieu minimum contenant du succinate, fumarate ou malate; confirmation de leur rôle dans le Dct. Cependant, une croissance résiduelle du mutant dctA dans ces milieux suggérerait une redondance des transporteurs d'acides Grdicarboxyliques. Une expérience de mutagenèse dans la souche AdctA, utilisant le transposon Tn5, combiné avec un criblage génétique sur la croissance dans le succinate, nous a permis d'identifier le deuxième transporteur DctPQM. DctPQM appartient à la famille des transporteurs TRAP (tripartite ATP-independent periplasmic). Un double mutant AdctAAdctPQM ne pousse pas dans du malate ou fumarate mais par contre présente une croissance résiduelle dans le succinate suggérant l'existence de transporteurs supplémentaires pour le succinate. En réalisant des expériences de compétitions nous avons démontré que le transporteur DctPQM est plus efficace que le transporteur DctA pour l'utilisation de succinate à une concentration de l'ordre du μΜ. Par contre, DctA est le transporteur le plus important pour une concentration de succinate de l'ordre du raM. Pour la première fois, deux systèmes de transport, un avec une forte- et un avec une faible-affinité (DctA et DctPQM) pour le succinate, sont coordonnés dans leur activité de transport des acides C4- dicarboxyliques, probablement contribuant à la versatilité de la bactérie. Ensuite, nous avons étudié la régulation du system Dct. En effectuant, en parallèle, une étude sur le phénomène de la répression catabolique (RC) chez P. aeruginosa, un lien entre la RC et le système Dct a été observé. La cascade des régulateurs formant la RC est composée de CbrA/CbrB, CrcZ et Crc. Crc est un répresseur traductionnel qui agit quand des sources de carbone préférées (comme les acides C4-dicarboxyliques) sont présentes dans le milieu. CrcZ est un petit ARN non-codant qui agit comme antagoniste de Crc. L'expression de CrcZ est induite par le système à deux composants CbrA/CbrB lorsque une source de carbone non-préférée est utilisée (comme le mannitol). Des nouvelles cibles du système CbrAB/CrcZ/Crc chez P. aeruginosa ont été identifiées grâce à une analyse du transcriptome des souches mutantes des régulateurs de la cascade. Parmi les cibles identifiées, les gènes dctA et dctPQM étaient présents. La RC régule l'expression des transporteurs dct en fonction de la concentration de succinate dans le milieu de croissance. Cette régulation est possible parce que, en même temps, les acides C4- dicarboxyliques régulent la RC. Dans un milieu contenant une grande concentration du succinate, le niveau d'expression de CrcZ est faible, donc Crc peut inhiber l'expression de ces ARN messagers cibles. Par contre, dans un milieu avec une faible concentration de succinate, l'augmentation de l'expression de CrcZ titre Crc et inhibe son activité. Ce modèle de régulation rétroactive est très important pour le phénomène de la RC, parce qu'il permet à la bactérie d'accorder une meilleure réponse à un changement environnemental. L'expression des gènes codant pour les transporteurs dct sont aussi régulés par la protéine chaperonne d'ARN Hfq. Hfq semble avoir le même effet traductionnelle que Crc, lorsqu'il y a une forte concentration de succinate. Nous avons ainsi observé une régulation négative de l'expression du gène dct Ρ et dctR, qui code pour un répresseur de la transcription de dctA. Nous avons aussi observé une régulation positive de la transcription de dctP par Hfq, probablement de façon indirecte. Enfin, une analyse du metabolome a était utilisée pour chercher les signaux internes modulant la RC et, en particulier, l'activité de la protéine senseur CbrA chez P. aeruginosa PAOl et P. putida KT2442. Les résultats de l'analyse sont en cours d'étude dans le laboratoire.

Excuse me, but your accent is very unusual. The complexity of establishing third languages in Inglourious Basterds. Applying a model of translation analysis to dubbing

The growing multilingual trend in movie production comes with a challenge for dubbing translators since they are increasingly confronted with more than one source language. The main purpose of this master’s thesis is to provide a case study on how these third languages (see CORRIUS and ZABALBEASCOA 2011) are rendered. Another aim is to put a particular focus on their textual and narrative functions and detect possible shifts that might occur in translations. By applying a theoretical model for translation analysis (CORRIUS and ZABALBEASCOA 2011), this study describes how third languages are rendered in the German, Spanish, and Italian dubbed versions of the 2009 Tarantino movie Inglourious Basterds. A broad range of solution-types are thereby revealed and prevalent restrictions of the translation process identified. The target texts are brought in context with some sociohistorical aspects of dubbing in order to detect prevalent norms of the respective cultures andto discuss the acceptability of translations (TOURY 1995). The translatability potential of even highly complex multilingual audiovisual texts is demonstrated in this study. Moreover, proposals for further studies in multilingual audiovisual translation are outlined and the potential for future investigations in this field thereby emphasised.

Spotting Translationese in two Corpora of Original and Translated Catalan Texts: an Empirical Approach

This research investigates the phenomenon of translationese in two monolingual comparable corpora of original and translated Catalan texts. Translationese has been defined as the dialect, sub-language or code of translated language. This study aims at giving empirical evidence of translation universals regardless the source language.Traditionally, research conducted on translation strategies has been mainly intuition-based. Computational Linguistics and Natural Language Processing techniques provide reliable information of lexical frequencies, morphological and syntactical distribution in corpora. Therefore, they have been applied to observe which translation strategies occur in these corpora.Results seem to prove the simplification, interference and explicitation hypotheses, whereas no sign of normalization has been detected with the methodology used.The data collected and the resources created for identifying lexical, morphological and syntactic patterns of translations can be useful for Translation Studies teachers, scholars and students: teachers will have more tools to help students avoid the reproduction of translationese patterns. Resources developed will help in detecting non-genuine or inadequate structures in the target language. This fact may imply an improvement in stylistic quality in translations. Translation professionals can also take advantage of these resources to improve their translation quality.

The influence of learning on evolution: a mathematical framework.

The Baldwin effect can be observed if phenotypic learning influences the evolutionary fitness of individuals, which can in turn accelerate or decelerate evolutionary change. Evidence for both learning-induced acceleration and deceleration can be found in the literature. Although the results for both outcomes were supported by specific mathematical or simulation models, no general predictions have been achieved so far. Here we propose a general framework to predict whether evolution benefits from learning or not. It is formulated in terms of the gain function, which quantifies the proportional change of fitness due to learning depending on the genotype value. With an inductive proof we show that a positive gain-function derivative implies that learning accelerates evolution, and a negative one implies deceleration under the condition that the population is distributed on a monotonic part of the fitness landscape. We show that the gain-function framework explains the results of several specific simulation models. We also use the gain-function framework to shed some light on the results of a recent biological experiment with fruit flies.
