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…

In search of the taste of terroir: a challenge sensory science

2020

International audience; The definition of terroir has evolved throughout history, from something clearly negative in the XVIth-XVIIIth century to a complex multi-parametric construct with positive connotations but also with many scientific unknowns. Terroir has always been linked more or less explicitly to the sensory properties of the resulting products. Wine consumers have little access to objective terroir information and even if they had, it would be very difficult for them to interpret in terms of wine quality. In Europe, the proxy for terroir is the Protected Designations of Origin (PDO) system, which is what consumers have come to know. According to INAO “It is the notion of soil (te…

L'influence de l'origine sociale sur les performances scolaires : par où passe-t-elle ?

2006

Using PISA 2000 data, this study presents an international comparison of the way social origin influences reading comprehension performances, looking at a variety of variables, some external to the school system, others internal. A variable's effect is strong in proportion to the strength of its association to father's occupation and degree to which it favors performance. The study uses the method of path analysis to distinguish between these two aspects. The French situation is presented, then compared to twelve other European Union countries. In all countries, social origin influences performance much more strongly through external variables than variables internal to the educational syst…

Holden Lori with Hass Crystal: The open-hearted way to open adoption. Helping your child growing up whole

l'Italia degli "ancora no": la ricerca delle origini e l'adozione aperta

2017

L’apertura e il diritto dei bambini a sapere sulla loro provenienza genetica sono diventate questioni chiave nei dibattiti circa l'adozione e un significativo cambiamento verso la trasparenza ha preso luogo nel contesto politico italiano. Ma l'ipotesi sulla possibilità di adozione aperta trova ancora vincoli e limitazioni evidenti nella legge di adozione italiana, che tutela il diritto della madre all'anonimato, anziché il diritto di origine e l'identità dei bambini. Tuttavia, recenti ricerche hanno dimostrato l'importanza di parlare attraverso l'apertura in caso di adozione, vale a dire l'atteggiamento della vita familiare a comunicare con onestà e sincerità riguardo la biologia e biografi…
