Main individual and product characteristics influencing in-mouth flavour release during eating masticated food products with different textures: mech…
2013
Research Areas: Life Sciences & Biomedicine - Other Topics; Mathematical & Computational Biology; A mechanistic model predicting flavour release during oral processing of masticated foods was developed. The description of main physiological steps (product mastication and swallowing) and physical mechanisms (mass transfer, product breakdown and dissolution) occurring while eating allowed satisfactory simulation of in vivo release profiles of ethyl propanoate and 2-nonanone, measured by Atmospheric Pressure Chemical Ionization Mass Spectrometry on ten representative subjects during the consumption of four cheeses with different textures. Model sensitivity analysis showed that the main paramet…
What a New Model of Skeletal Homologies Tells Us About Asteroid Evolution1
2000
The Extraxial-Axial Theory (EAT) is applied to the body wall homologies of asteroids. Attempts to characterize major plate systems of asteroids as axial or extraxial, particularly those that are highly organized into series, can be problematic. However, the Optical Plate Rule (OPR) is instrumental in establishing that ambulacrals and terminals are axial. It is equally clear that the region aboral to the marginal frame is a part of the perforate extraxial body wall (with the possible exception of the centrodorsal, which is likely imperforate extraxial). Previously established EAT criteria, particularly those strongly rooted in the embryologically expressed boundary between axial and extraxia…
Familiarity and liking playing a role on the perception of trained panelists: A cross-cultural study on teas
2015
Consumers cultural background is known to influence their food choice. To better understand the sensory perception across cultures, it is helpful to work with both a descriptive panel and consumers. This study examined how tea products of differing fermentation levels were described and liked by different cultures. Seven tea samples were evaluated by Korean and French trained panels and consumers. The trained panels evaluated the samples on appearance, flavor, and mouthfeel. The consumers rated the samples on acceptability and familiarity. The result indicated that both descriptive panels experienced varying degrees of taste and odor cross-modal interaction. On the unfamiliar samples, Frenc…
From attachment to damage: defined genes of Candida albicans mediate adhesion, invasion and damage during interaction with oral epithelial cells.
2010
Candida albicans frequently causes superficial infections by invading and damaging epithelial cells, but may also cause systemic infections by penetrating through epithelial barriers. C. albicans is an unusual pathogen because it can invade epithelial cells via two distinct mechanisms: induced endocytosis, analogous to facultative intracellular enteropathogenic bacteria, and active penetration, similar to plant pathogenic fungi. Here we investigated the molecular basis of C. albicans epithelial interactions. By systematically assessing the contributions of defined fungal pathways and factors to different stages of epithelial interactions, we provide an expansive portrait of the processes an…
Treatment of recurrent aphtous stomatitis: A systematic review
2022
Background: Recurrent Aphtous Stomatitis (RAS) is the most common process affecting the oral mucosa. It is painful, multifactorial and generally recurrent. The aim of this systematic review is to know the last treatment approaches and their effectivity.Material and Methods: we compared the outcome of different kind of treatments in terms of the improvement of the lesions, reduction of the size of those lesions and the time needed for their healing. Inclusion criteria were: clinical trials, articles written in English or Spanish and published less than 5 years ago.Results: we used the following keywords: treatment, aphtous stomatitis, canker sores; combined with Bool-ean operators AND y OR. …

The Effect of Negative Electronic Word of Mouth on Switching Intentions: A Social Interaction Utility Approach
2016
The aim of this chapter is to gain insight on negative eWom about brands from a sender perspective, taking into account individual and social factors. We develop and test a conceptual model using a sample of 302 Spanish active users of social networks who have complained online in 2013. This study provides several theoretical implications. Firstly, using the Social Interaction Utility framework, we analyse the influence of social motivations on negative eWom. Our results show that social motivations are the primary antecedents leading consumers to communicate their negative experiences to other consumers. Successful network sites should identify the effect of social motivations and manage t…

A method for determining the position and size of optimal sequence regions for phylogenetic analysis.
1995
The availability of fast and accurate sequencing procedures along with the use of PCR has led to a proliferation of studies of variability at the molecular level in populations. Nevertheless, it is often impractical to examine long genomic stretches and a large number of individuals at the same time. In order to optimize this kind of study, we suggest a heuristic procedure for detection of the shortest region whose informational content can be considered sufficient for significant phylogenetic reconstruction. The method is based on the comparison of the pairwise genetic distances obtained from a set of sequences of reference to those obtained for different windows of variable size and posit…
The hypoxia-inducible factor-responsive proteins semaphorin 4D and vascular endothelial growth factor promote tumor growth and angiogenesis in oral s…
2012
Growth and metastasis of solid tumors requires induction of angiogenesis to ensure the delivery of oxygen, nutrients and growth factors to rapidly dividing transformed cells. Through either mutations, hypoxia generated by cytoreductive therapies, or when a malignancy outgrows its blood supply, tumor cells undergo a change from an avascular to a neovascular phenotype, a transition mediated by the hypoxia-inducible factor (HIF) family of transcriptional regulators. Vascular endothelial growth factor (VEGF) is one example of a gene whose transcription is stimulated by HIF. VEGF plays a crucial role in promoting tumor growth and survival by stimulating new blood vessel growth in response to suc…
