Effect of two xeno-hormones, genistein and vinclozolin on development and exocrines and endocrines functions of submandibular salivary glands of Wist…

2012

The salivary glands are mixed glands: saliva (exocrine product) is involved inmaintaining oral homeostasis whereas endocrine secretions (eg growth factors) have aphysiological role (gametogenesis, osteogenesis, hypertension ..). In mammals, they displaysexual dimorphism suggesting a possible susceptibility to xeno-hormones.This manuscript presents the action of genistein (phytoestrogen) and/or vinclozolin (antiandrogenic)on the submandibular gland (SM) rats when performing an early exposure via themother (pregnancy, lactation) or an exposure during the growth period (from weaning toadulthood). The SM glands, collected at immature and young adult ages, have been analyzedaccording histologica…

Unvolvement of calcium signaling and MAP kinases in lipid taste perception

2013

In this work, we demonstrate that stromal interaction molecule 1 (STIM1), a sensor of Ca2+ depletion in the endoplasmic reticulum, mediates fatty acid–induced Ca2+ signaling in the mouse tongue and fat preference. We showed that linoleic acid (LA) induced the production of arachidonic acid (AA) and lysophosphatidylcholine (Lyso-PC) by activating multiple phospholipase A2 isoforms via CD36. This activation triggered Ca2+ influx in lingual CD36-positive taste bud cells (TBCs) purified from mouse CVP. LA also induced the production of Ca2+ influx factor (CIF). STIM1 was found to regulate LA-induced CIF production and the opening of store-operated Ca2+ (SOC) channels. Furthermore, CD36-positive…

Retro-nasal aroma release is correlated with variations in the in-mouth air cavity volume after empty deglutition.

2012

International audience; We hypothesized that interindividual differences in motor activities during chewing and/or swallowing were determining factors for the transfer of volatile aroma from the in-mouth air cavity (IMAC) toward the olfactory mucosa. In our first experiment, we looked for changes in IMAC volume after saliva deglutition in 12 healthy subjects. The mean IMAC volume was measured after empty deglutition using an acoustic pharyngometer device. Based on the time course of the IMAC volume after swallowing, we discerned two groups of subjects. The first group displayed a small, constant IMAC volume (2.26 mL ±0.62) that corresponded to a high tongue position. The second group displa…

Alienation and nihilism in the “affluent society”: the topicality of Augusto Del Noce

2021

Del Noce’s thought unravels over several decades on the stimulation of the great historical events in the 20th century (Totalitarianism, the Second World War, the Cold War, the Second Vatican Council, the Historic Compromise in Italy, etc.). Del Noce tackles the major philosophers of his time in this long journey of meditation: from Maritain to Gilson, from Gentile to Gramsci, from Löwith to Lukács and from Voegelin to Croce, not forgetting the dialogue with the classics from Descartes to Rosmini, and Marx to Gioberti. In this paper, I will concentrate mainly on his reflections around the so-called “affluent society” where he has gathered together, prophetically, those nihilist and anti-Chr…

A quelles saveurs les nourrissons sont-ils exposés dans la première année de vie ?

2010

International audience; Résumé Les consommations alimentaires des jeunes enfants sont influencées par leurs préférences alimentaires, lesquelles sont en partie déterminées par l'attirance pour les différentes saveurs (sucrée, salée, acide, amère et umami). Les expériences alimentaires précoces pourraient moduler cette attraction. Or aucun travail n'avait jusqu'à présent décrit les saveurs de l'alimentation des nourrissons au cours de la première année. Tel est l'objectif de cette étude. Les caractéristiques de l'alimentation de 76 nourrissons ont été consignées par leurs parents pendant une semaine par mois au cours de la première année. Ce suivi a conduit à recenser 2902 aliments a priori …

Implication of an odorant-binding protein in precopulatory behaviour and interaction with the bacterial microbiota

2023

Chemoreception allows animals to detect nutritive food and avoid toxic compounds. Volatile and non-volatile chemical compounds, which are detected by olfactory and gustatory sensory organs, can trigger feeding and reproductive behaviours in animals such as Drosophila melanogaster. Inside chemosensory organs, perireceptor proteins like odorant-binding proteins (OBPs) serve to transport odorant and tastant molecule to dedicated receptors. OBPs are not only involved in chemoreception but also in several other functions. A recent study revealed an interaction between insect microbiota and OBP expression while another one showed that microbes can promote nutrient harvesting on food. In our proje…

The Role of Perceived Control in the Psychophysiological Responses to Disgust of Subclinical OCD Women

2019

Obsessive‒compulsive disorder (OCD), and especially contamination obsessions and washing compulsions, has been related to disgust. However, when its cardiovascular correlates have been studied, contradictory results have been found, including heart rate accelerations and decelerations. The aim of this study is to analyze emotional, cognitive, and cardiovascular responses in nonclinical (control) and subclinical participants with obsessive‒compulsive contamination/washing symptoms when confronted with a disgusting stimulus. Twenty-seven participants (14 subclinical OCD) completed a behavioral avoidance task with a contamination-based stimulus while their heart rate and subjective variables w…

The natural history of breast carcinoma in patients withor = 10 metastatic axillary lymph nodes before and after the advent of adjuvant therapy: a mu…

2005

BACKGROUND The majority of patients with breast carcinoma with ≥ 10 metastatic axillary lymph nodes (ALNs) develop recurrent disease within 5 years from diagnosis. The purpose of the current study, performed retrospectively, was to characterize the natural history of this subset of patients, both before and after the advent of adjuvant anthracycline-based chemotherapy and tamoxifen. METHODS Retrospectively, patients with primary breast carcinoma (N = 882) with ≥ 10 metastatic ALNs, treated between 1954 and 1998, were selected from 3 institutions: The University of Texas M. D. Anderson Cancer Center (Houston, TX); the Institut Gustave Roussy (Villejuif, France); and Hospital Clinico Universi…
