Consommation alimentaire des nourrissons et des enfants en bas âge en France en 1997
1999
Resume En 1981 et 1989, deux enquetes nationales decrivaient l'evolution de la consommation alimentaire des nourrissons francais. En 1997, une troisieme enquete a ete realisee par les memes equipes suivant la meme methode. Population et methodes L'echantillon, representatif, est constitue de 660 enfants de 1 a 30 mois. La quantite de chaque aliment ingere par chaque enfant a ete relevee pendant 3 jours. On a calcule la valeur energetique de la ration, l'apport en protides, lipides, glucides, mineraux, vitamines et acide linoleique, la repartition des apports entre les repas de la journee et le pourcentage de l'energie provenant des differents aliments. Resultats De 1989 a 1997, la part des …
Apports nutritionnels en France en 2005 chez les enfants non allaités âgés de moins de 36 mois
2008
Resume Contexte Malgre l’interet scientifique de sa connaissance, le statut nutritionnel des enfants francais en bas âge n’a ete que peu etudie. Objectifs Evaluer les apports energetiques, macro- et micronutritionnels des enfants francais âges de un a 36 mois. Procedure experimentale Une enquete alimentaire transversale a ete realisee de janvier a mars 2005 sur un echantillon representatif des nourrissons et enfants francais en bas âge, tenant compte de l’âge des enfants, de l’activite professionnelle de la mere, de la categorie socioeconomique de la famille, mais en excluant les enfants totalement ou partiellement nourris au sein. Sujets Sept cent six enfants ont ete repartis en 11 groupes…
Emerging Immnunohistochemical evidence for Direct Peripheral Control of Endocannabinoids on the Gastrointestinal Tract and Pancreas of Obese (fa/fa)a…
2012
This research has the objective to investigate immunohistochemical expression of CB1 receptor and its probable changes in Gastroenteropancreatic system (GEP) of obese and lean Zucker rats and understand the endocannabinoid pathophysiological implications in the obesity. Male obese (fa/fa) and lean Zucker rats 6 weeks old were obtained from Harlan Italy Srl; the rats were sacrificed at 8, 12 and 16 weeks old. Normal rats also were sacrificed. Specimens of stomach, jejunum-ileum and pancreas were fixed in Bouin’s mixture and embedded in paraffin; obtained sections were processed with anti-CB1 (Biosource Europe SA) by Streptavidin-Biotin-Complex Method. The findings show that CB1 receptor is e…
Assessment of test-meal induced autonomic arousal in anorexic, bulimic and control females
1998
This study attempted to measure three different physiological responses to food intake in eating disordered subjects. Skin conductance level (SCL), heart rate and electroencephalogram were recorded before, during and after a test-meal in 42 females (14 anorexic inpatients, 10 bulimic outpatients and 18 control subjects). Significant increase in SCL during the meal was found in anorexics only. Pre-meal SCL was lower in bulimics than in controls and anorexics. No changes were found on heart rate or electroencephalogram in all groups of subjects. This suggests that anorexic inpatients may display a measurable arousal when confronted with a meal, whereas bulimic outpatients and control subjects…

Different Behaviour of Plasma Antioxidant Status after Red Wine Consumption in Subjects of the Same Sex: A Preliminary Report
2012
<p>Several studies report that the plasma antioxidant capacity (PAC) increases after a single ingestion of red wine. However, data on the different behaviour of PAC after food intake in subjects of the same sex are still lacking. On the basis of these observations some investigations were undertaken in order to evaluate the effects of red wine intake on PAC in a homogeneous groups of healthy female volunteers (n=18). Additionally, the possible correlation between increase of PAC values and increase in uric acid levels was also assessed. PAC and uric acid concentrations were determined before wine intake and 50, 120 and 240 minutes thereafter. The results obtained following these studi…
Vigilance and food intake rate in paired and solitary Zenaida DovesZenaida aurita
2011
We quantified vigilance during feeding in the Zenaida Dove Zenaida aurita, a tropical species with stable pair-bonds and year-round territoriality. Both males and females decreased the proportion of time spent vigilant by 30% when feeding with their partner compared with when feeding alone. This reduction was achieved through increasing the length of inter-scan duration, while scan duration remained constant. No evidence was found for coordination of vigilance between pair members. The equal investment in vigilance by male and female Zenaida Doves might be related to the mutual benefits of long-term pair-bonding.
Role of polysialic acid (PSA) in the control of food intake and body weight
2013
Hypothalamus plays a major role in the regulation of energy homeostasis by the presence of neural circuits controlling food intake. These circuits are plastic and can be rewired during adulthood. We hypothesized that synaptic plasticity can occur during physiological conditions. We have shown that synaptic contact on hypothalamic anorexigen POMC neurons are rewired in mouse upon high fat diet (HFD). This synaptic process is mandatory to adjust energy intake and requires the glycan PSA (polysialic acid). PSA promotes synaptic plasticity in the brain by the weakening of cell-to-cell interaction by addition on NCAM (neural cell adhesion molecule). We hypothesized that a defect in brain synapti…
Parasite-induced alteration of plastic response to predation threat: increased refuge use but lower food intake in Gammarus pulex infected with the a…
2014
6 pages; International audience; Larvae of many trophically-transmitted parasites alter the behaviour of their intermediate host in ways that increase their probability of transmission to the next host in their life cycle. Before reaching a stage that is infective to the next host, parasite larvae may develop through several larval stages in the intermediate host that are not infective to the definitive host. Early predation at these stages results in parasite death, and it has recently been shown that non-infective larvae of some helminths decrease such risk by enhancing the anti-predator defences of the host, including decreased activity and increased sheltering. However, these behavioura…
