Salt and Aroma Compound Distributions Influence Flavour Release and Temporal Perception While Eating Hot-Served Flans.
2021
International audience; To counteract the negative effect of salt overconsumption on health, strategies have been developed to reduce the salt content in food products. Among them, two promising strategies based on odour-induced saltiness enhancement and the heterogeneous distribution of flavour compounds were combined and assessed in four-layer cream-based snacks. To investigate the relationship between saltiness enhancement, temporal release and perception of flavour compounds in hot snacks with heterogeneous distribution of salt and aroma compounds, complementary techniques were used: nose space PTR-Tof-MS (Proton Transfer Reaction-Time of Flight–Mass Spectrometry) to assess the release …
Geometry of conjugated double bonds of CLA isomers in a commercial mixture and in their hepatic 20∶4 metabolites
1999
Rats were fed a fat-free diet for 2 wk. After this period, while maintaining the animals on the same diet, the rats were given intragastrically 180 mg per day of a mixture of conjugated linoleic acids (CLA) as triacylglycerols. Gas chromatography mass spectrometry (GC-MS) analyses of this mixture, as well as hydrazine reduction and GC-MS and GC-Fourier transform infrared analyses of the resulting monoenes, revealed the presence of two major isomers, the 9c,11t- and the 10t,12c-18:2 accompanied by smaller amounts of the 8t, 10c and the 11c, 13t-18:2 isomers. Minor quantities of cis,cis and trans,trans conjugated isomers also were detected. The total fatty acid methyl esters from the liver li…
A detailed identification study on high-temperature degradation products of oleic and linoleic acid methyl esters by GC–MS and GC–FTIR
2012
GC-MS and GC-FTIR were complementarily applied to identify oxidation compounds formed under frying conditions in methyl oleate and linoleate heated at 180ºC. The study was focused on the compounds that originated through hydroperoxide scission that remain attached to the glyceridic backbone in fats and oils and form part of non-volatile molecules. Twenty one short-chain esterified compounds, consisting of 8 aldehydes, 3 methyl ketones, 4 primary alcohols, 5 alkanes and 1 furan, were identified. In addition, twenty non-esterified volatile compounds, consisting of alcohols, aldehydes and acids, were also identified as major non-esterified components. Furanoid compounds of 18 carbon atoms form…
Exploring the profiles of children with autism spectrum disorder: association with family factors.
2019
This study aimed to identify different profiles of children with autism spectrum disorder (ASD) without intellectual disability (ID) and maternal factors characteristic of these profiles. Participants were 89 children between 7 and 11 years old and their mothers, distributed in two groups, 52 children with ASD and 37 with typical development (TD). Based on the children’s adaptive, behavioral, and pragmatic manifestations, three clusters were obtained in the ASD group. Children with the most serious difficulties in all the domains assessed were assigned to Cluster 1, whereas the children in Cluster 3 were characterized by relatively minor problems. Cluster 2 comprised children with moderate …
Enhancing daily living skills in four adults with autism spectrum disorder through an embodied digital technology-mediated intervention
2019
Abstract Background The acquisition of daily living skills is fundamental in the education of people with Autism Spectrum Disorder (ASD), especially of those with Intellectual Disability (ID), because this can significantly contribute to their autonomy, self-confidence and overall life satisfaction. The purpose of this study was to assess the impact of an embodied Digital Technology (DT)-mediated intervention, compared to a Treatment-As-Usual (TAU) intervention, for enhancing two daily living skills: washing dishes and doing laundry. Method Four males of between 25 and 37 years old with ASD and ID participated in the study. The two interventions were based on audio and picture prompting ins…
A Review of the State-of-the-Art of Assistive Technology for People with ASD in the Workplace and in Everyday Life
2019
Part 8: Digital Divide and Social Inclusion; International audience; Autism, also known as autism spectrum disorder (ASD), is an incurable brain-based disorder that refers to a wide range of complex neurodevelopment disorders characterised by marked difficulties in communication and social skills, repetitive behaviour, highly focused interests and sensory sensitivity. Autism can present challenges for affected people at the work environment and in everyday life. The barrier for individuals with ASD increases further with changing environmental situations. Individuals with ASD have limited abilities to isolate their Five senses and often experience over- or under-sensitivity to sounds, touch…
A framework of evidence-based practice for digital support, co-developed with and for the autism community
2020
A wide array of digital supports (such as apps) have been developed for the autism community, many of which have little or no evidence to support their effectiveness. A Delphi study methodology was used to develop a consensus on what constitutes good evidence for digital supports among the broader autism community, including autistic people and their families, as well as autism-related professionals and researchers. A four-phase Delphi study consultation with 27 panel members resulted in agreement on three categories for which evidence is required: reliability, engagement and effectiveness of the technology. Consensus was also reached on four key sources of evidence for these three categor…
Metaphor comprehension in children with and without autism spectrum disorder
2020
Abstract Metaphor comprehension was studied in three groups of children from 6 to 12 years old: a group with autism spectrum disorder with level 2 severity (ASD, n = 22) and two comparison groups with typical development: one matched with the ASD group on chronological age (TCD group, n = 22) and the other matched on linguistic age (TLD group, n = 22). The TCD group performed better than the TLD group, which performed better than the ASD group, on the comprehension of both conventional and novel metaphors, with better performance found on conventional metaphors than on novel ones. We suggest that both linguistic and extralinguistic competencies (usually limited in level 2 ASD) would be nece…
DESARROLLO EVOLUTIVO Y SEVERIDAD DEL TRASTORNO DEL ESPECTRO AUTISTA EN NIÑOS: RELACIÓN CON EL CI
2016
El Trastorno del Espectro Autista (TEA) es un trastorno del neurodesarrollo que se caracteriza principalmente por la alteración en el área de la comunicación social. Es importante su identificación temprana para su intervención. Nuestro estudio pretende estudiar qué áreas del desarrollo están más afectadas y su relación con la severidad del diagnóstico. Para ello participaron 51 familias con niños con diagnóstico clínico de Trastorno del Espectro Autista. Se administraron pruebas de CI verbal y no-verbal, el test Gars-2 y el Inventario de Desarrollo de la Battelle. Los resultados mostraron que las áreas de comunicación expresiva y personal/social estaban más deterioradas en los sujetos de l…
Evaluation of a French parent-training program in young children with autism spectrum disorder
2018
Abstract Parent training programs (PTs) in young children with autism spectrum disorders (ASDs) are known to reduce parenting stress and improve child's behavior and parent-child interactions. Few PTs are available to French speaking families. In order to provide them with this type of intervention, we developed a French parent-training program of 12 bimonthly sessions and three individual home visits based on applied behavior analysis. The purpose of this study is to evaluate the social validity and efficacy of this new PT on eighteen parents who have a child with ASD and developmental delay. For 16 parents, the PT was considered effective, the objectives targeted important and the strateg…
