Capacités d'ajustement énergétique à court terme chez le nourrisson entre 10 et 15 mois : premiers résultats (prix SFN 2015)
2016
Introduction et but de l’etude L’equilibre de la balance energetique est maintenu soit par l’ajustement des depenses energetiques soit par l’ajustement des apports energetiques. L’enquete americaine « 2002 Feeding infants and toddlers » laisse penser qu’une diminution des capacites d’ajustement energetique se produirait autour de 11 mois. Ces capacites se deterioreraient sous l’effet des pratiques de nourrissage notamment au cours de la diversification alimentaire. Aucune etude n’a mesure les capacites d’ajustement energetique a court terme chez des nourrissons entre 10 et 15 mois. L’objectif principal de ce projet etait donc d’evaluer les capacites d’ajustement energetique a court terme a …

Short-term caloric compensation ability in infants below 15 months old
2020
International audience; Background and aims In infancy, a too rapid weight gain is a risk factor associated with overweight. Growth is linked to the infant's ability to adjust energy intake depending on the energy density of foods. Evidence regarding the behavioral aspects of appetite control ability in infancy is sparse. The objective was to study the short-term energy adjustment ability of, first, exclusively milk fed infants before the onset of complementary feeding (CF) and, second, of infants at 11 mo and 15 mo. Methods Caloric compensation ability was assessed in infants by adapting a preload paradigm. Before CF, the ‘preload' was a feed with formula made more or less caloric by conce…
Rapid odorant release in mammalian odour binding proteins facilitates their temporal coupling to odorant signals.
2010
; We have measured the effect of rat odorant-binding protein 1 on the rates of ligand uptake and liquid-to-air transfer rates with a set of defined odorous compounds. Comparison of observed rate constants (k(obs)) with data simulated over a wide range of different kinetic and thermodynamic regimes shows that the data do not agree with the previously held view of a slow off-rate regime (k(off) <0.0004 s(-1)). We propose that a rapid koff would be a necessary requirement for such a system, since slow odorant-release rates would result in significant decorrelation between the olfactory world and odour perception.

Application of seaweeds to develop new food products with enhanced shelf-life, quality and health-related beneficial properties
2017
International audience; Edible seaweeds are a good source of antioxidants, dietary fibers, essential amino acids, vitamins, phytochemicals, polyunsaturated fatty acids, and minerals. Many studies have evaluated the gelling, thickening and therapeutic properties of seaweeds when they are used individually. This review gives an overview on the nutritional, textural, sensorial, and health-related properties of food products enriched with seaweeds and seaweed extracts. The effect of seaweed incorporation on properties of meat, fish, bakery, and other food products were highlighted in depth. Moreover, the positive effects of foods enriched with seaweeds and seaweed extracts on different lifestyl…
Alkylated Aromatic Thioethers with Aggregation‐Induced Emission Properties—Assembly and Photophysics
2019
In this contribution, we present the synthesis and self-assembly of alkylated thioethers with interesting photophysical properties. To this end, the emission, absorption and excitation spectra in organic solvents and as aggregates in water were measured as well as the corresponding photoluminescence quantum yields and lifetimes. The aggregates in aqueous media were visualized and measured using transmission electron microscopy. Besides that, crystal structures of selected compounds allowed a detailed discussion of the structure–property relationship. Furthermore, the mesomorphic behavior was investigated using polarized optical microscopy (POM) as well as differential scanning calorimetry (…
Telerilevamento e GIS per la valutazione e il monitoraggio delle isole di calore in ambiente urbano
2017
The techniques of spatial analysis and Remote Sensing represent an useful tool for the knowledge and the study of the Urban Heat Island phenomenon (English acronym UHI). In this study, among the different causes that lead to the generation of the event, those regarding physical features of the surface and the presence of different land use/cover such as: the high cover of urban areas and the lack of green areas have been examined. The Remote Sensing techniques allow to create maps of the land use/cover, then, in order to estimate the different in temperature due to the distance to the vegetation, the temperature of the bodies already tested have been compared with a thermal map. In detail t…
The complementary structural studies of the double metal cyanide type catalysts for the ring opening polymerization of the oxiranes
2016
Przeprowadzono badania strukturalne katalizatorów dimetalocyjankowych (DMC) z dwoma rodzajami ligandów organicznych. Zaproponowano wyjaśnienie etapów przebiegu krzywych otrzymanych metodą analizy termograwimetrycznej i różnicowej kalorymetrii skaningowej (TG/DSC) badanych katalizatorów. Wykazano obecność kilku stopni związania ligandów w kompleksach DMC. Na podstawie wyników badań z wykorzystaniem absorpcji rentgenowskiej (XAS) stwierdzono, że centrum aktywne katalizatora stanowi atom cynku. W bezpośrednim sąsiedztwie atomów Zn wykryto obecność atomów Cl, natomiast w najbliższych sferach koordynacyjnych atomu Zn nie wykryto atomów tlenu.
