The Dynamics of Aroma Release during the Consumption of Candies with Different Structures

2014

This chapter aims at investigating the role of candy texture on the dynamics of aroma release using dynamic instrumental and sensory methods. The highest in vivo release, monitored using proton transfer reaction mass spectrometry (PTR-MS), was obtained for the 2% gelatin sample for all aroma compounds. The temporal dominance of sensations (TDS) method highlighted that the dominant sensation for the liquid product was the “strawberry” note. For other products, the temporal characteristics of perceptions were more complex. Data highlighted that aroma release resulted from interaction between product properties and oral behavior. Some relations with the dynamics of perception have been establi…

In midlife, women experience hormonal changes due to menopausal transition. A decrease especially in estradiol has been hypothesized to cause loss of muscle mass. This study investigated the effect of menopausal transition on changes in lean and muscle mass, from the total body to the muscle fiber level, among 47–55-year-old women. Data were used from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study, where 234 women were followed from perimenopause to early postmenopause. Hormone levels (estradiol and follicle stimulating hormone), total and regional body composition (dual-energy X-ray absorptiometry (DXA) and computed tomography (CT) scans), physical activity level (self-reported…

Hormone replacement therapy improves contractile function and myonuclear organization of single muscle fibres from postmenopausal monozygotic female …

2013

Ageing is associated with a decline in muscle mass and strength leading to increased physical dependency in old age. Postmenopausal women experience a greater decline than men of similar age in parallel with the decrease in female sex steroid hormone production. We recruited six monozygous female twin pairs (55-59 years old) where only one twin pair was on hormone replacement therapy (HRT use = 7.8 ± 4.3 years) to investigate the association of HRT with the cytoplasmic volume supported by individual myonuclei (myonuclear domain (MND) size,) together with specific force at the single fibre level. HRT use was associated with a significantly smaller (∼27%; P < 0.05) mean MND size in muscle fib…

Role of aroma–matrix interactions on perception of structured emulsions

2011

The impact of the composition of spreads on in vivo aroma release and aroma perception was investigated using online proton transfer reaction mass spectrometry (PTR-MS) and sensory methodologies. Consumption of model products spread on bread induced a significant increase in aroma release and better discrimination in aroma perception, compared to when the product was tasted pure from a spoon. Dynamic release of a series of 10 aroma compounds was slower with the increase in solid fat content, and the quantity decreased when proteins were added. Sensory ranking of model products mostly confirmed the release results.

Le bien-être alimentaire du quotidien à l’institution hospitalière : de nouveaux enjeux normatifs.

2020

Cet article interroge la façon dont les questions sanitaires jouent sur les normes en matière de santé. Dans une perspective diachronique et culturellement située, l’objectif de l’article sera, dans un premier temps, de montrer que le bien-être est une valeur évolutive aux prismes des attentes sociétales. D’un bien-être aux contours fermés et délimités, les enjeux sociaux et la forte médiatisation de la nutrition en font une valeur qui évolue, dont la qualification reste toujours difficile à saisir. Dans un second temps, l’article propose la construction d’un outil de mesure du bien-être alimentaire en contexte hospitalier afin d’intégrer des éléments subjectifs et actuels autour des attent…

Understanding the Influence of Eating Patterns on Binge Drinking: A Mediation Model

2020

Background: Binge drinking is an important health problem, and it has been related to binge eating and fat intake in animal models, but this relationship has not been tested in humans. The first objective of this study was to analyze whether binge eating and fat intake are related to binge drinking in a youth sample. The second objective was to analyze whether binge eating and fat intake mediate the relationship between individual factors associated with binge eating and fat intake (sex, body mass index (BMI), drive for thinness, body dissatisfaction, eating styles, impulsivity, and food addiction) and binge drinking. Methods: A sample of 428 undergraduate students filled out several questi…

Development and Validation of the Test of Orthorexia Nervosa (TON-17)

2021

This study aims to develop and validate a new self-report questionnaire to measure orthorexia nervosa (ON). Based on a current review of the scientific literature and interviews with people at risk of orthorexia, 40 items were selected to test orthorexia nervosa (TON-40). A total sample of 767 individuals (M = 26.49, SD = 9.66, 56.98% women) participated in the study. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and composite construct analysis (CCA) were performed to find an appropriate model of sufficient reliability and validity and stable construction. Convergent validation was performed regarding the correlation of the TON-17 with another measure of ON (OR…

Victim-Naming in the Murder Mystery Series Twin Peaks: A Corpus-Stylistic Study

2020

Corpus linguistics is advancing rapidly in the study of a wide variety of genres, but is still at its infancy in the study of TV series, a genre daily consumed by millions of viewers. Murder mystery series are one of the most popular and proliferous, but no studies, to date, have used corpus-stylistics methodologies in the analysis of the pivotal character of the victim in the whole narrative. This paper applied this methodology hoping to shed some light on the quantitative and qualitative relationship between the participation roles of the characters, and the frequency and distribution of victim-naming choices in the dialogue of the two first seasons of the acclaimed TV series Twin Peaks. …

Evidence for the production of three massive vector bosons with the ATLAS detector

2019

A search for the production of three massive vector bosons in proton–proton collisions is performed using data at TeV recorded with the ATLAS detector at the Large Hadron Collider in the years 2015–2017, corresponding to an integrated luminosity of 79.8 fb−1. Events with two same-sign leptons ℓ (electrons or muons) and at least two reconstructed jets are selected to search for . Events with three leptons without any same-flavour opposite-sign lepton pairs are used to search for , while events with three leptons and at least one same-flavour opposite-sign lepton pair and one or more reconstructed jets are used to search for . Finally, events with four leptons are analysed to search for and .…
