Prevalence, antimicrobial resistance and genetic diversity of Campylobacter coli and Campylobacter jejuni in Ecuadorian broilers at slaughter age

Thermotolerant Campylobacter spp. are a major cause of foodborne gastrointestinal infections worldwide. The linkage of human campylobacteriosis and poultry has been widely described. In this study we aimed to investigate the prevalence, antimicrobial resistance and genetic diversity of C. coli and C. jejuni in broilers from Ecuador. Caecal content from 379 randomly selected broiler batches originating from 115 farms were collected from 6 slaughterhouses located in the province of Pichincha during 1 year. Microbiological isolation was performed by direct plating on mCCDA agar. Identification of Campylobacter species was done by PCR. Minimum inhibitory concentration (MIC) values for gentamicin, ciprofloxacin, nalidixic acid, tetracycline, streptomycin, and erythromycin were obtained. Genetic variation was assessed by RFLP-flaA typing and Multilocus Sequence Typing (MLST) of selected isolates. Prevalence at batch level was 64.1%. Of the positive batches 68.7% were positive for C. coli, 18.9% for C. jejuni, and 12.4% for C. coli and C. jejuni. Resistance rates above 67% were shown for tetracycline, ciprofloxacin, and nalidixic acid. The resistance pattern tetracycline, ciprofloxin, and nalidixic acid was the dominant one in both Campylobacter species. RFLP-flaA typing analysis showed that C. coli and C. jejuni strains belonged to 38 and 26 profiles respectively. On the other hand MLST typing revealed that C. coli except one strain belonged to CC-828, while C. jejuni except 2 strains belonged to 12 assigned clonal complexes (CCs). Furthermore 4 new sequence types (STs) for both species were described, whereby 2 new STs for C. coli were based on new allele sequences. Further research is necessary to estimate the impact of the slaughter of Campylobacter positive broiler batches on the contamination level of carcasses in slaughterhouses and at retail in Ecuador

O trabalho em perspectiva: identidade e subjetividade

O trabalho “moderno” foi construído no jogo de força entre dominantes e dominados e manifestou-se sob três tendências: a racionalidade econômica; a procura de integração normativa ao modo de produção capitalista mediante a instrumentalização dos trabalhadores; o surgimento de uma identidade operária por via da ação coletiva. A partir da segunda metade do séc. XX, aparecem novos modos de produção e de gestão que provocam mudanças significativas no mundo do trabalho em nível global. O trabalho e (ou) sua falta tornam-se objetos de insatisfação, até mesmo de sofrimento. O trabalho entra em crise. As mesmas tendências podem ser observadas no Brasil. Nos últimos trinta anos, desenvolvem-se formas variadas de trabalho informal, inclusive no campo da economia solidária, como forma de resposta ao “apartheid” social dos trabalhadores e à profunda fratura econômica da sociedade brasileira. A preocupação, neste artigo, é procurar saber em que medida o trabalho, hoje, pode construir o trabalhador como sujeito social e se tornar a experiência fundadora de identidade social e de ação coletiva, debate que abrange aspectos históricos, teóricos e empíricos. http://dx.doi.org/10.5902/223667257929

Regulation of nestin expression by thrombin and cell density in cultures of bone mesenchymal stem cells and radial glial cells

BACKGROUND: Bone marrow stromal cells and radial glia are two stem cell types with neural phenotypic plasticity. Bone marrow mesenchymal stem cells can differentiate into osteocytes, chondrocytes and adipocytes, but can also differentiate into non-mesenchymal cell, i.e. neural cells in appropriate in vivo and in vitro experimental conditions. Likewise, radial glial cells are the progenitors of many neurons in the developing cortex, but can also generate astrocytes. Both cell types express nestin, an intermediate filament protein which is the hallmark of neural precursors. RESULTS: In this study, we demonstrate that thrombin, a multifunctional serine protease, stimulates the growth of radial glial cells (RG) and mesenchymal stem cells (MSCs) in a dose-dependent manner. In RG, the mitogenic effect of thrombin is correlated with increased expression of nestin but in MSCs, this mitogenic effect is associated with nestin down-regulation. Both cell types express the PAR-1 type receptor for Thrombin and the effect of Thrombin on both cell types can be mimicked by its analogue TRAP-6 activating specifically this receptor subtype or by serum which contains various amount of thrombin. Moreover, we also demonstrate that serum deprivation-induced expression of nestin in MSCs is inhibited by high cell density (> 50,000 cells/cm2). CONCLUSION: This work shows that thrombin stimulates the growth of both RG and MSCs and that nestin expression by MSCs and RG is regulated in opposite manner by thrombin in vitro. Thrombin effect is thus associated in both cell types with a proliferating, undifferentiated state but in RG this involves the induction of nestin expression, a marker of immaturity for neural progenitors. In MSCs however, nestin expression, as it corresponds to a progression from the mesenchymal "undifferentiated", proliferating phenotype toward acquisition of a neural fate, is inhibited by the mitogenic signal

« Littéradanse », Quand la danse contemporaine s’empare du texte littéraire

L’ouvrage de Mélanie Mesager, publié en 2018 et intitulé Littéradanse, Quand la chorégraphie s’empare du texte littéraire. Fanny de Chaillé, Daniel Dobbels, Antoine Dufeu et Jonah Bokaer est issu d’un travail mené en 2015 dans le cadre d’un Master 2 dirigé par Julie Perrin à l’Université Paris 8. Il s’agit d’une étude menée à partir de quatre spectacles de danse contemporaine à la croisée du mouvement dansé et du texte littéraire. L’auteur entend ici donner corps au concept de « littéradanse » en s’attachant à des œuvres chorégraphiques qui ne se réduisent ni au texte énoncé ni à la partition dansée, mais qui naissent de leur mise en présence. Elle propose plusieurs façons d’appréhender les inflexions réciproques de la littérature et de la danse, tout en cherchant à décrypter comment un sens mouvant se construit dans le temps du spectacle.Mélanie Mesager’s book, published in 2018 and entitled Littéradanse, Quand la chorégraphie s’empare du texte littéraire. Fanny de Chaillé, Daniel Dobbels, Antoine Dufeu et Jonah Bokaer is the result of a work carried out in 2015 as part of a Master 2 program led by Julie Perrin at the University of Paris 8. This is a study based on four contemporary dance performances at the crossroads of dance and literary text. The author intends here to give substance to the concept of “littéradanse” by focusing on choreographic works that are not to be reduced to the text, nor to the dance performed. She proposes several ways of understanding the reciprocal inflections of literature and dance, while seeking to figure out how a moving meaning is constructed during the performance

A Rotating Fluidized Bed in a Static Geometry: Experimental Proof of Concept

The new concept of a rotating fluidized bed in a static geometry (RFB-SG) is presented (1). The rotating motion of the particle bed and the tangential fluidization of the solids are obtained by the tangential injection of the fluidization gas via multiple gas inlet slots in the outer cylindrical wall of the fluidization chamber. The new fluidization concept is experimentally investigated and proven using either large diameter, low density polymer particles or small diameter, higher density Alumina particles

Interprétation géométrique de la capacité et des performances de systèmes à diversité

- Notre étude a pour cadre les systèmes de transmission à diversité. Nous analysons tout d'abord l'influence d'une erreur d'estimation du canal, et déduisons l'expression analytique de la capacité ainsi dégradée d'un système OPRA (Optimal Power and Rate Adaptation). Ensuite, nous proposons une interprétation géométrique de cette capacité en nous basant sur la théorie des courbes dites de Bézier. Après avoir passé en revue certaines propriétés héritées de cette structure particulière, nous proposons alors une expression matricielle de cette capacité, ainsi qu'une méthodologie de construction graphique. Pour conclure, nous présentons une application concernant le dimensionnement de motif de pilotes, pour des systèmes multi-porteuse à étalement fréquentiel (Multi-Carrier Spread-Spectrum)

Nouveau décodeur à complexité réduite pour codes convolutifs de rendement 1/2

Les codes convolutifs peuvent être décodés de façon optimale à l'aide l'algorithme de Viterbi (VA). Nous proposons un décodeur à entrée souple dans lequel l'algorithme de Viterbi est employé pour identifier le vecteur d'erreur plutôt que le message d'information avec une métrique appropriée. Ce type de décodage permet d'éviter la mise en oeuvre d'un nombre important d'opérations ACS (Add Compare Select). Nous montrons que les performances atteintes sont proches de l'optimum tout en bénéficiant d'une réduction de la complexité qui est d'autant plus importante que le rapport signal à bruit (SNR) est favorable. Par exemple, pour des SNR supérieurs à 3 dB et dans le cas d'une transmission avec la modulation BPSK sur canal gaussien, au moins 88% des ACS peuvent être évités
