Résumé : Croton urucurana Baillon (Euphorbiaceae), plant species popularly known in Brazil as “sangra-d’água”, is commonly found in Mato Grosso do Sul State (midwestern Brazil), where its latex is popularly used to treat several types of cancer. Despite the ethnopharmacological significance of the species, no phytochemical or cytotoxic studies of its latex have been published. In this context, the aim of the present study was to assess the cytotoxic activity of crude extracts, fractions and isolated compound from the latex of C. urucurana and to investigate the effects of crourorb A1 on the viability, apoptosis, cell cycle and cell migration of human hepatocarcinoma cell lines (Huh-7). Also, we have evaluated the viability of Huh-7 cells treated with crourorb A1 in 3D collagen gels. The cytotoxicity was detected using the sulforhodamine B (SRB) assay against six human cancer cells lines and one nontumor NIH/3T3 cell line (murine fibroblast). Studies on the mechanism of cell death of crourorb A1 were conducted in different test systems in vitro. The bioactive ethyl acetate phase obtained from the latex of C. urucurana afforded a novel cyclic peptide, [1−9-NαC]-crourorb A1, that proved active against NCIADR/ RES (ovary, multidrug-resistance phenotype) cells with the same potency as doxorubicin (positive control) and inactive up to the highest concentration tested against nontumor NIH/3T3 cells (GI50 = > 250 μg/mL). Crourorb A1 treatment decreases the cell viability of Huh-7 at dose and time dependent manner associated with induction of apoptosis by caspase 3/7 activation and increasing expression of pro-apoptotic proteins: Bak, Bid, Bax, Puma, Bim, and Bad and clived-caspase3 protein. The JNK/MAP pathway is involved in this induced cell death. Crourorb A1 effect is also associated with G2/M phase cell cycle arrest. In parallel, we observed that crourorb A1 treatment resulted in an increase of cyclin-dependent kinase (CDK1), cyclin B1 and cyclin D1 expressions. A significant reduction of Huh-7 cells migration by crourorb A1 can be assessed and we also show that cells grown on 3D collagen gels exhibited increased resistance to crourorb A1 when compared to 2D cell culture.
Croton urucurana Baillon (Euphorbiaceae), est une plante très connue et utilisée en médecine traditionnelle au Brésil, la «sangra-d’água» retrouvée dans l'État du Mato Grosso do Sul (région Centre-Ouest du Brésil). Son latex est abondamment utilisé en médecine traditionnelle dans le traitement de plusieurs types de cancer. En dépit de son importance ethnopharmacologique, on ne trouve aucune étude sur sa composition chimique ou sur sa potentielle activité anti-cancéreuse. L’objectif de ce travail a été d'évaluer l'activité cytotoxique des extraits totaux, fractions d’extraits et de molécules purifiées, isolées du latex de C. urucurana. Nous avons étudié plus particulièrement les effets du crourorb A1 sur la viabilité, l'apoptose, le cycle cellulaire et la migration de cellules issues de carcinome hépatocellulaire humaine (Huh-7). Nous avons également évalué l’effet du crourorb A1sur la viabilité des cellules Huh-7 cultivées dans les gels de collagène en 3D. L' activité cytotoxique ont été réalisées par le test à la sulforhodamine B sur six lignées cellulaire cancéreuses et sur une lignée cellulaire non cancéreuse de fibroblastes murins, les cellules NIH/3T3. L'étude phytochimique de la fraction ‘acétate d'éthyle’ du latex de C. urucurana bioguidé a permis d’obtenir un nouveau cyclopeptide que nous avons nommé [1-9-NαC]-crourorb A1. Le crourorb présente une cytotoxicité puissante sur la lignée cellulaire cancéreuse NCI-ADR/RES (ovaire, le phénotype de multirésistance) à un niveau équivalent à celle de la doxorubicine (témoin positif). Ce composé est de plus pratiquement inactif (GI50 = >250 μg/mL) sur la lignée non cancéreuse NIH/3T3. L'évaluation de la cytotoxicité in vitro du crourorb A1 (test wst1) sur les cellules Huh-7 a démontré que la viabilité des cellules est inhibée de manière dose et temps-dépendant. Nous avons mesuré une forte activation des caspases 3 et 7 et une nette augmentation de l’expression des protéines pro-apoptotiques (Bak, Bid, Bax, Puma, Bim et Bad) ainsi que de la caspase 3 clivée par le crourorb A1. Nous avons également déterminé que la voie de signalisation JNK-MAPkinase semble nécessaire à l’induction de la mort cellulaire des cellules Huh-7 traitées au crourorb A1. Le crourob A1 induit un arrêt du cycle cellulaire en phase G2/M. En parallèle, les expressions de la cycline-dépendante kinase CDK1, des cyclines B1 et D1 sont augmentées après traitement au crourorb A1. De plus, le crourorb A1 a un effet inhibiteur significatif de la migration des cellules Huh-7, en présence ou absence de mitomycine C. Nous avons également confirmé, l’effet inhibiteur du crourob A1 sur la viabilité des cellules Huh7 cultivées en 3D dans les gels de collagène 1 et démontré que les cellules cultivées en 3D semblent plus résistantes au crourorb A1 par rapport aux cultures en monocouche 2D.
Croton urucurana Baillon (Euphorbiaceae) é uma espécie arbórea conhecida popularmente no Brasil como “sangra d´água”, comumente encontrada no estado de Mato Grosso do Sul, onde seu látex tem sido utilizado na medicina popular no tratamento de vários tipos de câncer. Apesar de sua importância etnofarmacológica, não há relatos de estudos relacionados à sua composição química ou atividades anticâncer na literatura. Nesse contexto, o objetivo do presente estudo foi avaliar a atividade citotóxica de extratos, fases, frações e da substância isolada do látex de C. ururucurana e investigar os mecanismos celulares e moleculares in vitro responsáveis pela citotoxicidade da substância isolada considerando seu potencial apoptótico e influência sobre a progressão do ciclo celular em uma linhagem de hepatocarcinoma celular humano (Huh-7), bem como, os efeitos desta substância sobre a migração e viabilidade de células Huh-7 cultivadas em geis de colágeno em 3D. O ensaio de citotoxicidade in vitro foi realizado com o corante sulforrodamina B (SRB) em seis linhagens de células neoplásicas humanas e uma linhagem de células não neoplásicas NIH/3T3 (fibloblasto murinho). Os estudos de mecanismos de ação com crourorb A1 foram conduzidos em diferentes sistemas-teste in vitro. O estudo fitoquímico biomonitorado da fase bioativa acetato de etila do látex de C. urucurana resultou no isolamento de um novo ciclopeptídeo denominado [19-NαC]-crourorb A1, que apresentou potente atividade citotóxica frente à linhagem de células neoplásicas NCI-ADR/RES (ovário com fenótipo de resistência a múltiplos fármacos), com a mesma potência que a doxorrubicina (controle positivo), e foi inativa até a maior concentração testada (GI50 = >250 μg/mL) frente à linhagem de células não neoplásicas 3T3. A exposição de células Huh-7 ao crourorb A1 resultou em uma diminuição da viabilidade celular de maneira dose e tempo-dependentes. Nós observamos um aumento da atividade de caspases 3 e 7 e um aumento da expressão de proteínas próapoptóticas (Bak, Bid, Bax, Puma, Bim e Bad) e caspase 3 clivada após tratamento com crourorb A1. Além disso, observamos que a via de sinalização celular MAP/JNK foi necessária para induzir a morte celular em células Huh-7 tratadas com crourorb A1. Os efeitos de crourorb A1 foram também associados com o acúmulo de células na fase G2/M do ciclo celular. Em paralelo, as expressões da cinase dependente da ciclina (CDK1), ciclina B1 e ciclina D1 foram aumentadas após tratamento com crourorb A1. Foi demonstrado também o envolvimento de crourorb A1 na redução da migração de células Huh-7 cultivadas na presença e ausência de mitomicina C. A avaliação da viabilidade de células Huh-7 cultivadas em geis de colágeno em 3D apontou uma maior resistência destas células ao crourorb A1 quando comparadas com a cultura de células em 2D.

Résumé : International audience
A versatile sol-gel route has been developed for the preparation of hierarchical porous silica membrane material with highly dispersed platinum nanoparticles (Pt-NPs). The outstanding feature of the "one pot" synthesis developed in this work lies in the successful preparation of a stable complex suspension made of silica sol, multi-scale porogens and Pt nanoparticles. The multi-scale porogens were based on non-ionic triblock copolymers and aqueous latex suspension to create mesopores and macropores, respectively, with finely tuned pore size and organization. For further functionalization of the membranes, Pt nanoparticles of about 4 nm in diameter were prepared by irradiating with microwaves (MW) the Pt precursors added in the starting suspension. This original path is suggested to enable a pre-organization of Pt nanoparticles in the ordered mesoporous structure. The suspensions were then deposited as thin films on either dense or macroporous supports, and further thermally treated at 450°C to remove the porogen units. Hierarchical porous layers composed of micropores (<2 nm), ordered mesopores (∼4 nm) and macropores (∼70 nm) with or without Pt were prepared and characterized. The resulting membranes are foreseen to exhibit great potential as multifunctional membranes for gas separation coupled with catalytic reaction. © The Royal Society of Chemistry 2008.

We propose a theoretical framework within which information on the vocabulary of a given corpus can be inferred on the basis of statistical information gathered on that corpus. Inferences can be made on the categories of the words in the vocabulary, and on their syntactical properties within particular languages. Based on the same statistical data, it is possible to build matrices of syntagmatic similarity (bigram transition matrices) or paradigmatic similarity (probability for any pair of words to share common contexts). When clustered with respect to their syntagmatic similarity, words tend to group into sublanguage vocabularies, and when clustered with respect to their paradigmatic similarity, into syntactic or semantic classes. Experiments have explored the first of these two possibilities. Their results are interpreted in the frame of a Markov chain modelling of the corpus' generative processe(s): we show that the results of a spectral analysis of the transition matrix can be interpreted as probability distributions of words within clusters. This method yields a soft clustering of the vocabulary into sublanguages which contribute to the generation of heterogeneous corpora. As an application, we show how multilingual texts can be visually segmented into linguistically homogeneous segments. Our method is specifically useful in the case of related languages which happened to be mixed in corpora.

Résumé : International audience
The objective of this study was to examine the water relations and hydraulic architecture and vulnerability to cavitation in Virola surinamensis and V. michelii and to compare to similar measurements in Eperua falcata. In several previous reports Virola was seen to have a rather narrow range of xylem pressure potentials (Ψx) near zero in the course of a wet-season day while having water fluxes quite close to Eperua. We tested the hypothesis that the narrow range of Ψx might be consistent with very high hydraulic conductivities of stems, roots and shoots and high vulnerability to cavitation in Virola compared to Eperua. When this hypothesis proved false we concluded that the previous determinations of Ψx might be wrong in Virola due to latex. We re-examined the determination of Ψx in Virola by the pressure chamber technique and compared results to determination of Ψleaf by the thermocouple psychrometer technique and found that the likely range of Ψx are more negative than previously reported. Problems concerning the determination of Ψx in species with latex are discussed.

Without prior knowledge, distinguishing different languages may be a hard task, especially when their borders are permeable. We develop an extension of spectral clustering -- a powerful unsupervised classification toolbox -- that is shown to resolve accurately the task of soft language distinction. At the heart of our approach, we replace the usual hard membership assignment of spectral clustering by a soft, probabilistic assignment, which also presents the advantage to bypass a well-known complexity bottleneck of the method. Furthermore, our approach relies on a novel, convenient construction of a Markov chain out of a corpus. Extensive experiments with a readily available system clearly display the potential of the method, which brings a visually appealing soft distinction of languages that may define altogether a whole corpus.

In this article, some first elements of a computational modelling of the grammar of the Martiniquese French Creole dialect are presented. The sources of inspiration for the modelling is the functional description given by Damoiseau (1984), and Pinalie's & Bernabe's (1999) grammar manual. Based on earlier works in text generation (Vaillant, 1997), a unification grammar formalism, namely Tree Adjoining Grammars (TAG), and a modelling of lexical functional categories based on syntactic and semantic properties, are used to implement a grammar of Martiniquese Creole which is used in a prototype of text generation system. One of the main applications of the system could be its use as a tool software supporting the task of learning Creole as a second language.
Nous présenterons dans cette communication les premiers travaux de modélisation informatique d'une grammaire de la langue créole martiniquaise, en nous inspirant des descriptions fonctionnelles de Damoiseau (1984) ainsi que du manuel de Pinalie & Bernabé (1999). Prenant appui sur des travaux antérieurs en génération de texte (Vaillant, 1997), nous utilisons un formalisme de grammaires d'unification, les grammaires d'adjonction d'arbres (TAG d'après l'acronyme anglais), ainsi qu'une modélisation de catégories lexicales fonctionnelles à base syntaxico-sémantique, pour mettre en oeuvre une grammaire du créole martiniquais utilisable dans une maquette de système de génération automatique. L'un des intérêts principaux de ce système pourrait être son utilisation comme logiciel outil pour l'aide à l'apprentissage du créole en tant que langue seconde.
