Development of new food and pharmaceutical products: Nutraceuticals and food additives
2020
The market of nutraceuticals and foods elaborated with natural additives are constantly growing and leading researchers and professionals of pharmaceutical and food industry to develop new products and reconsider the formulation of processed food. However, these products can only be insert into the market after extensive and well-performed scientific studies that clarify the mechanisms by which bioactive compounds can improve health status beyond nutrition or can replace conventional food additives perceived as "unhealthy" or "unfamiliar" by consumers. Therefore, scientific evidence regarding the actual health benefits and preservation/enhancement of food attributes are the crucial step in …
Monod-based ‘single-data’ strategy for biodegradation screening tests
2020
Environmental contextObtaining biodegradation data over time can be difficult, especially when dealing with environmental compartments of increasing complexity. We evaluated the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time experimental measurement, and found that environmental information related to potential chemical persistence can be derived. The applicability of this ‘single-data’ strategy is illustrated using simulated and experimental data for several compounds. AbstractInformation obtained from biodegradability tests, e.g. half-life (t50) or kinetics parameters, is relevant in environmental risk assessment of new chemicals. In thes…
Neuronal inhibition of the autophagy nucleation complex extends lifespan in post-reproductive C. elegans
2017
AbstractAutophagy is a ubiquitous catabolic process, which causes cellular bulk degradation of cytoplasmic components and thereby regulates cellular homeostasis. Inactivation of autophagy has been linked with detrimental effects to cells and organisms. The antagonistic pleiotropy theory postulates that fitness promoting genes during youth are harmful during aging (Williams 1957). On this basis we examined genes mediating post-reproductive longevity using an RNA interference screen. From this screen we identified 30 novel regulators of post-reproductive longevity including pha-4. Through downstream analysis of pha-4 we identify that genes governing the early stages of autophagy up until the …
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.
Quality and volatile compounds in red wine at different degrees of dealcoholization by membrane process
2019
This study investigated the effect of different degrees of dealcoholization on volatile compounds, phenols and sensory characteristics of red wine (cv. Montepulciano d’Abruzzo). The wine with an initial alcohol content of 13.2% v/v was partially dealcoholized by membrane process with a decrease of alcohol degree as follows: − 4.9; − 6.3; − 7.8, − 9.2 and − 10.5% v/v. Osmotic distillation has proved effective in preserving a satisfactory odorous profile, as samples with an alcohol residue of 8.3% v/v (− 4.9%) and 6.9% v/v (− 6.3%) showed good esters retention: more than 84% and 82%, respectively. Similarly, colour and taste, evaluated by flavonoids and phenolic compounds, remained almost unc…
Evaluación participativa del territorio con enfoque de equidad: adaptación y validación de la Place Standard al contexto español
2022
OBJECTIVE Translation and cross-cultural adaptation to the Spanish context of the Place Standard tool to undertake participatory evaluations in place-based communities. METHOD A back-translation method was used to obtain an adapted version of the original Place Standard tool. The translated version was reviewed by a multidisciplinary committee of experts and validated using the Delphi method. RESULTS The final version of the adapted Place Standards tool (Entornos de Vida in Spanish) consists of 14 dimensions and 99 items. 21% of the items presented semantic difficulties during the translation. Total consensus through the Delphi panel was reached on 72% of the items. The analysis resulted in…
Health-related messages about physical activity promotion: an analysis of photographs on social networking sites of universities
2016
ABSTRACTThe main aim of this study was to examine how different physical activity domains are represented on the official social media sites of Spanish universities, through a content analysis of the photographs. Our results show that the representation of different physical activity domains is not balanced. While the analysed images do promote a message of gender equality in sedentary and leisure time physical activity behaviour, pictures illustrating active commuting and disabled groups were under-represented. We conclude that Internet-based physical activity promotion in university settings must to be guided by the principles of ‘health-promoting universities’ in the sense of promoting a…
RELACIÓN ENTRE ESTRÉS PARENTAL Y HABILIDADES LINGÜÍSTICAS EN NIÑOS CON TEA
2016
Abstract:The objectives of this study were: 1) Compare the perceived parental stress between a group of parents of children with ASD and a group of parents of children with typical development. The rest of the objectives are focused on the analysis of the ASD group.2) Compare the perceived parental stress between the parents of the ASD children with language and the parents of the ASD children without language. 3) Analyze the relationship between the perceived parental stress and the child’s receptive linguistic skills. 4) Analyze the relationship between the perceived parental stress and the child’s expressive linguistic skills. The Parenting Stress Index scale (the child domain) was used …
In the shadow of threatening norms: How students with visual impairment contest and reproduce institutional positions
2020
This article focuses on semi-narrative guided interviews with students with visual impairment (VI) who attend a state-approved special school for students with VI at the time of the interview, although they had different previous experiences in both segregated and inclusive schools. We are conducting a qualitative analysis from the perspective of teenagers concerning how they negotiate institutional ascriptions of (dis)abilities. We have selected interview sequences of two young people: (a) Kai: self-confidence and internalized self-doubt and (b) Felix: between fighting and claiming ableist divides. Our analyses reveal the different ways of how Kai and Felix each contest the ableist divide…
Enhancement of Anticipatory Postural Adjustments by Virtual Reality in Older Adults with Cognitive and Motor Deficits: A Randomised Trial.
2021
Background: Postural activities involved in balance control integrate the anticipatory postural adjustments (APA) that stabilize balance and posture, facilitating arm movements and walking initiation and allowing an optimal coordination between posture and movement. Several studies reported the significant benefits of virtual reality (VR) exercises in frail older adults to decrease the anxiety of falling and to induce improvements in behavioural and cognitive abilities in rehabilitation processes. The aim of this study was thus to test the efficiency of a VR system on the enhancement of the APA period, compared to the use of a Nintendo Wii system. Methods: Frail older adults (n = 37) were i…
