Cell mechanisms of gustatory lipids perception and modulation of the dietary fat preference.
2014
Dietary lipids are usually responsible of several metabolic disorders. Recent compelling evidences suggest that there is a sixth taste modality, destined for the detection of oro-gustatory fats. The lipid-binding glycoprotein CD36, expressed by circumvallate papillae (CVP) of the mouse tongue, has been shown to be implicated in oro-gustatory perception of dietary lipids. We demonstrate that linoleic acid (LA) by activating sPLA2, cPLA2 and iPLA2 via CD36, produced arachidonic acid (AA) and lyso-phosphatidylcholine (Lyso-PC) which triggered Ca(2+) influx in CD36-positive taste bud cells (TBC), purified from mouse CVP. LA induced the production of Ca(2+) influx factor (CIF). CIF, AA and Lyso-…
CD36 and taste of fat.
2012
Purpose of review This review explores the recent literature on the role of CD36 in the taste of fat, eating behavior and obesity risk in rodents and humans. Recent findings During the last decade, evidence was accumulated supporting the existence of a taste of fat responsible for the spontaneous preference for lipid-rich foods. Surprisingly, the multifunctional membrane-associated protein CD36 appears to play a significant role in this system in rodents. Recently, another plausible gustatory lipid sensor, the GPR120, was also identified in mice, revealing that the mechanism involved in oral fat detection is more complex than initially expected. Interestingly, lingual CD36 and GPR120 displa…
Effect of Choice Feeding in the Pre-weaning Period on the Growth Performance of Calves during the Pre- and Post-weaning Periods
2017
The aim of this study was to investigate the effects of choice feeding in the pre-weaning period on the growth performance of calves during the pre- and post-weaning period. It is possible that high Crude protein (CP) intake during the pre-weaning period may improve post-weaning performance of calves. Currently, there is insufficient data available on the effect of pre-weaning feeding method on post-weaning performance of calves; therefore the aim of this study was to examine the effect of choice feeding on growth performance of calves during the pre and post-weaning period. Results: Twenty eight male and 28 female Holstein calves were assigned to two different feeding systems. After weanin…
Assessing Preferences in Patients with Head and Neck Squamous Cell Carcinoma: Phase I and II of Questionnaire Development.
2020
Shared-decision making for head and neck squamous cell carcinoma (HNSCC) is challenged by the difficulty to integrate the patient perception of value within the framework of a multidisciplinary team approach. The aim of this study was to develop a questionnaire to assess the preferences of HNSCC patients with respect to the disease trajectory, expected treatment, and toxicities. In accordance with the standardized EORTC Quality of Life Group&rsquo
Car sharing demand estimation and urban transport demand modelling using stated preference techniques
2008
The research deals with the use of the stated preference technique (SP) and transport demand modelling to analyse travel mode choice behaviour for commuting urban trips in Palermo, Italy. The principal aim of the study was the calibration of a demand model to forecast the modal split of the urban transport demand, allowing for the possibility of using innovative transport systems like car sharing and car pooling. In order to estimate the demand model parameters, a specific survey was carried out inside the urban area of Palermo. The survey focused on the morning rush hour and involved mainly employees, self-employed workers and students (about 500 respondents) whose final destination was lo…
Comparison of relaxation techniques in virtual reality for breast cancer patients
2019
A number of studies demonstrated that virtual reality (VR) featuring pleasant scenarios and relaxing narratives is effective in promoting relaxation in users, both in healthy and pathological contexts. One important field for application of relaxing VR is breast cancer, because of therapy-related distress and changes in body imagine experienced by patients during the care process. However, comparisons between different relaxation techniques adapted to virtual reality are rare. In the present study, the same virtual environment has been integrated with audio narratives designed according to two different relaxation techniques (respiration control and body scan). As initial exploration, 16 br…
Poly-Victimization in Polish Adolescents: Risk Factors and the Moderating Role of Coping.
2018
This study aimed to investigate the prevalence of poly-victimization in Polish adolescents and assess factors associated with poly-victimization risk across different ecological levels. This study further examined whether coping styles could moderate the impact of poly-victimization on emotional well-being. Participants were 454 adolescents, aged between 13 and 19 years, from an urban region of Poland. Adolescents completed self-report measures assessing community, school, and family risks, along with a peer nomination task measuring social preference. Teachers also completed a measure assessing adolescent problem behaviors. Findings revealed that the majority of the sample (70%) experience…
STUDY ON CONSUMERS' BEHAVIOR CONCERNING BERRIES CONSUMPTION IN ITALY
2014
In Italy, the cultivated land of berries shows a positive trend, nevertheless berries still remain a productive segment of niche and luxury in the Italian agri-food system. In the world, the interest for these productions is high for their healthy aspects that have a strong appeal to the consumers. The objectives of this study are to know the consumers behavior of berries and the determinants of purchase in Italy in order to improve the management of the producing and retailers companies for increase the competitiveness of the supply chain. The results obtained through a multivariate analysis show some difference among the consumers interviewed. The most important results of this study is t…
COVID-19 Drives Consumer Behaviour and Agro-Food Markets towards Healthier and More Sustainable Patterns
2020
This study examines the extant state of research into our understanding of the impact of the coronavirus pandemic in its early stages on food-purchasing behaviour. As such, it includes a summary and categorisation of the findings, extending to consumption preferences worldwide. After the indiscriminate stockpiling of food, which was witnessed in many countries following the implementation of the lockdown, the impact of COVID-19 (COronaVIrus Disease-2019) on consumer habits has inversely varied in function of personal attitudes, individual and household experiences, and characteristics. Specific contexts, and the financial, economic, and logistic nature of these contexts, have also been foun…
What Does It Mean to Be Popular in Spain? Mixed-Method Analysis of Popularity as Perceived by Teenagers and Their Teachers
2019
A great part of the research in adolescent popularity is based on sociometric methods, not always distinguishing between social preference (acceptance or likeability) and perceived popularity (visibility or salience), which has practical and theoretical implications. The aim of this work was to analyze the features that a sample of 406 Spanish adolescents (53.2% girls, M = 16.76 years) and their teachers (n = 26, 50% women) associated with perceived popularity. The data analysis established three main themes that categorize perceived popularity: behaviors, developmental traits, and other resources, which include both peer-valued and not valued characteristics. Qualitative and quantitative c…
