Effects of energy density on the liking for sweet drinks and on caloric adjustment conditioning after exposure in children

2014

The contribution of energy density from sweet drinks to energy intake in children needs clarification. The objective was to study the influence of energy conditioning on liking and on caloric adjustment after sweet drinks exposure. Children aged 8 to 11 (n=44) were exposed to distinctly flavored sweetened drinks: a high-energy (HE: 150kcal) and a no-energy version (NE: 0kcal). They received either 2 or 7 exposures to each drink during a 4-wk conditioning period; no exposure during a 3-wk stability period; 3 exposures to both drinks, for which the association between the flavor and the energy density was switched, during a 4-wk extinction period. Flavor liking and food intake during the meal…

Détermination et transmission du goût. Importance des expériences précoces

2013

Compte tenu que les préférences et habitudes alimentaires sont acquises très précocement il est important de mieux comprendre l’impact des expériences précoces sur l’acceptation des fruits et légumes lors de la diversification alimentaire et pendant les premières années de vie. Au cours de cette présentation, des résultats d’études expérimentales ou observationnelles portant sur l’impact de l’allaitement, des pratiques de diversification (variété de l’offre, exposition répétée) et des pratiques éducatives sur l’acceptation des fruits et légumes seront présentées. La transmission des préférences alimentaires peut commencer au cours de la vie intra-utérine. Il a été montré que des nouveau-nés…

Characterisation and distribution of deposited trace elements transported over long and intermediate distances in north-eastern France using Sphagnum…

2015

Abstract Trace elements in the form of particulate matter can be transported downwind from their emission sources and may have negative effects on human health and ecosystems. The transport of trace elements is often studied by monitoring their accumulation in mosses. The aim of this study was to characterise and describe the distribution of deposited trace elements transported over long and intermediate distances in north-eastern France, a location far from the main emission sources. We analysed the trace element accumulation in Sphagnum capillifolium in 54 ombrotrophic peatlands distributed in six regions of France (Alps, Jura, Massif Central, Morvan, Rhone corridor and Vosges). The conce…

Assessing short- and long-term repeatability and stability of personality in captive zebra finches using longitudinal data

2012

11 pages; International audience; Assessing behavioural consistency is crucial to understand the evolution of personality traits. In the present study, we examined the short- and long-term repeatability and stability of two unrelated personality traits - exploratory tendencies and struggling rate - using captive female zebra finches (Taeniopygia guttata). We performed two experimental sessions of behavioural tests with a 7-mo interval, which represents up to one quarter of a zebra finch's life expectancy. We showed that, overall, exploratory tendencies and struggling rate were significantly repeatable in the short term. However, only exploratory tendencies were repeatable in the long term. …

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…

Pentamidine rescues contractility and rhythmicity in a Drosophila model of myotonic dystrophy heart dysfunction

2015

Up to 80% of individuals with myotonic dystrophy type 1 (DM1) will develop cardiac abnormalities at some point during the progression of their disease, the most common of which is heart blockage of varying degrees. Such blockage is characterized by conduction defects and supraventricular and ventricular tachycardia, and carries a high risk of sudden cardiac death. Despite its importance, very few animal model studies have focused on the heart dysfunction in DM1. Here, we describe the characterization of the heart phenotype in a Drosophila model expressing pure expanded CUG repeats under the control of the cardiomyocyte-specific driver GMH5-Gal4. Morphologically, expression of 250 CUG repeat…

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…
