Comparative efficacy of Zataria multiflora Boiss., Origanum compactum and Eugenia caryophyllus essential oils against E. coli O157:H7, feline caliciv…

2013

Abstract Ready-to-eat salads using baby-leaf and multi-leaf mixes are one of the most promising developments in the fresh-cut food industry. There is great interest in developing novel decontamination treatments, which are both safe for consumers and more efficient against foodborne pathogens. In this study, emulsions of essential oils (EOs) from Origanum compactum (oregano), Eugenia caryophyllus (clove), and Zataria multiflora Boiss (zataria) were applied by spray (0.8 ml) after the sanitizing washing step. The aim was to investigate their ability to control the growth of potentially cross-contaminating pathogens and endogenous microbiota in commercial baby leaves, processed in a fresh-cut…

Translating culture: Charles Mungoshi's Waiting for the Rain

2008

In Waiting for the Rain Charles Mungoshi chose a western form, the novel, and a western language, English, to try and convey the deep changes at work in Zimbabwean society at the time. This paper focuses on both aspects: first, the adaptation of the novelistic genre to Zimbabwean culture, and second, the defamiliarization of the English language, which is not Mungoshi's mother tongue. What is questioned is whether the incorporation of essentially oral elements, belonging to and borrowed from a specific culture and language, which are initially peripheral and foreign to the dominant "English" culture, can transform both Zimbabwean culture and English culture – in other words, Waiting for the…

Drivers-Inspired Ants for Solving the Vehicle Routing Problem with Time Windows

2016

International audience; In our study, we develop a method that merges two information sources within ants colony optimization heuristic. Namely artificial ants which occurs for short term optimization and transporter's vehicles that occurs in long term and continuous optimization toward solving the real-world vehicle routing problem. This study is supported by a transporter (Upsilon) of the region of l'Yonne in France and a transport and logistics software development company (Tedies). Our method suits for transporters that use human planners to make decisions about their tours and intending to move to computer planners without drastically upsetting the drivers habits. Hence, the pledge of …

Caractérisation de la distribution spatiale des communautés microbiennes du sol et de ses déterminants à l’échelle du paysage

2014

International audience; Depuis plusieurs années, des approches biogéographiques ont été développées pour mieux caractériser la distribution spatiale des communautés microbiennes du sol, comprendre les processus écologiques mis en œuvre et identifier les filtres environnementaux déterminant leur diversité et leur structure. Ces approches ont été mises en œuvre à différentes échelles spatiales allant de celle de la parcelle agricole à celle d’un territoire et d’un continent. Elles ont permis de mettre en évidence que les communautés microbiennes du sol sont distribuées suivant des patterns biogéographiques non aléatoire et que ces dernières sont soumises à des processus déterministes (sélecti…

New perspectives and approaches in plant growth-promoting rhizobacteria research

2007

International audience; In the context of increasing international concern for food and environmental quality, use of Plant Growth-Promoting Rhizobacteria (PGPR) for reducing chemical inputs in agriculture is a potentially important issue. PGPR are root-colonizing bacteria that exert beneficial effects on plant growth and development, but they can be also employed in the control of plant pathogens, for enhancing the efficiency of fertilizers, and for degrading xenobiotic compounds. This book provides an update by renowned international experts on the most recent advances in the ecology of these important bacteria, the application of innovative methodologies for their study, their interactio…

Etude des mécanismes d'action d'une immunothérapie par un lipide A, seul ou associé à l'oxaliplatine, dans des modèles de cancers coliques

2013

Colorectal cancer is a major public health concern in France. Resistance to standard chemotherapy requires development of novel therapeutic approaches. In the past decades, our team showed the immunotherapeutic properties of lipid A in a model of colon cancer in rats. 95% of rats bearing small carcinomas were cured following treatment by lipid A. The study of mechanisms underlying this immunotherapy allowed us to show that the antitumor effect of lipid A was dependent on cytotoxicity induced by granzyme B produced by intratumoral neutrophils. Indeed, we have shown that, in the tumor microenvironment, neutrophils produced granzyme B and had a pro-tumorigenic N2 phenotype. When rats were trea…
