Exploring the diversity of listeria monocytogenes biofilm architecture by high-throughput confocal laser scanning microscopy and the predominance of …

2015

ABSTRACT Listeria monocytogenes is involved in food-borne illness with a high mortality rate. The persistence of the pathogen along the food chain can be associated with its ability to form biofilms on inert surfaces. While most of the phenotypes associated with biofilms are related to their spatial organization, most published data comparing biofilm formation by L. monocytogenes isolates are based on the quantitative crystal violet assay, which does not give access to structural information. Using a high-throughput confocal-imaging approach, the aim of this work was to decipher the structural diversity of biofilms formed by 96 L. monocytogenes strains isolated from various environments. Pr…

Population Structure and Comparative Genome Hybridization of European Flor Yeast Reveal a Unique Group of Saccharomyces cerevisiae Strains with Few G…

2014

Wine biological aging is a wine making process used to produce specific beverages in several countries in Europe, including Spain, Italy, France, and Hungary. This process involves the formation of a velum at the surface of the wine. Here, we present the first large scale comparison of all European flor strains involved in this process. We inferred the population structure of these European flor strains from their microsatellite genotype diversity and analyzed their ploidy. We show that almost all of these flor strains belong to the same cluster and are diploid, except for a few Spanish strains. Comparison of the array hybridization profile of six flor strains originating from these four co…

Rbt1 Protein Domains Analysis in Candida albicans Brings Insights into Hyphal Surface Modifications and Rbt1 Potential Role during Adhesion and Biofi…

2013

Cell wall proteins are central to the virulence of Candida albicans. Hwp1, Hwp2 and Rbt1 form a family of hypha-associated cell surface proteins. Hwp1 and Hwp2 have been involved in adhesion and other virulence traits but Rbt1 is still poorly characterized. To assess the role of Rbt1 in the interaction of C. albicans with biotic and abiotic surfaces independently of its morphological state, heterologous expression and promoter swap strategies were applied. The N-terminal domain with features typical of the Flo11 superfamily was found to be essential for adhesiveness to polystyrene through an increase in cell surface hydrophobicity. A 42 amino acid-long domain localized in the central part o…

Intimacy in Cinema: Critical Essays on English Language Film

2014

International audience; Though intimacy has been a wide concern in the humanities, it has received little critical attention in film studies. This collection of essays investigates both the potential intimacy of cinema as a medium and the possibility of a cinema of intimacy where it is least expected. As a notion defined by binaries--inside and outside, surface and depth, public and private, self and other--intimacy, because it implies sharing, calls into question the boundaries between these extremes, and the border separating mainstream cinema and independent or auteur cinema. Following on Thomas Elsaesser's theories of the relationship between the intimacy of cinema and the cinema of int…

Cinémas libertaires : au service des forces de transgression et de révolte

2015

International audience; Les contributeurs, parmi lesquels de nombreux cinéastes et plasticiens, explorent le corpus méconnu des films issus des idéaux libertaires, depuis la lutte armée jusqu'aux pensées de la non-violence. Cet ouvrage décrit la diversité des pratiques inventées par les réalisateurs engagés ; les formes spécifiques nées de films revendiquant une action concrète, que celle-ci soit d'ordre révolutionnaire, pédagogique ou simplement émancipatrice ; les puissances de déplacement, de destruction et de proposition théorique dynamisées par l'esprit anarchiste. Il met en circulation des documents rares ou inédits concernant l'histoire des cinémas libertaires et la parole de certain…

Gas sensors arrays (electronic noses) : a study about the speed/accuracy ratio

2000

Abstract New Fingerprint Mass Spectra (FMS) systems claim for a higher precision, a reduced analysis time, and a lower drift, compared with Gas Sensors Arrays ‘Electronic Noses’. We demonstrated in this study that metal oxide gas sensors may have highly improved performances for both accuracy and run time, when used in optimum conditions. The different noise components were quantified referring to popular words (equivalent of ethanol concentration) using the transfer function of the sensor. It was pointed out that sample surrounding greatly affects the noise level, and that the signal-to-noise ratio may be dramatically increased, reducing the distortion generally assessed between sensor and…

Electronic noses : specify or disappear

2000

Abstract When the quality control is achieved by using GC or GC/MS, the apparatus must comply with the applicable norms, but what about “electronic noses”? End users demand for formal specifications for selectivity, sensitivity, repeatability and sample throughput. The behavioural modelling of electronic olfactometers may provide specifications for these required parameters. This will allow both the measure itself, and evaluate the influence of the experimental errors on the sample classification. Users may expect to find a methodology allowing the performances of systems to be checked before any final decision and during routine use. We have demonstrated that the system sensitivity and log…
