Human salivary proteome and sensitivity to bitterness
2012
Bitterness is present in every day beverages (e.g. coffee) and foods (e.g. vegetables such as cruciferous plants). However, bitterness is perceived differently among individuals and some foods considered as healthy may be rejected due to their bitter taste. Several genetic (eg. genetic polymorphism of bitter taste receptors) or environmental (eg. age, medications) factors partly explain the interindividual variability in bitterness perception. However, other peri-receptor factors may intervene, in particular salivary composition. First, in order to investigate the link between salivary proteome and sensitivity to bitterness, the detection threshold to the bitter taste of caffeine was measur…
A novel Usher protein network at the periciliary reloading point between molecular transport machineries in vertebrate photoreceptor cells.
2008
Contains fulltext : 69178.pdf (Publisher’s version ) (Closed access) The human Usher syndrome (USH) is the most frequent cause of combined deaf-blindness. USH is genetically heterogeneous with at least 12 chromosomal loci assigned to three clinical types, USH1-3. Although these USH types exhibit similar phenotypes in human, the corresponding gene products belong to very different protein classes and families. The scaffold protein harmonin (USH1C) was shown to integrate all identified USH1 and USH2 molecules into protein networks. Here, we analyzed a protein network organized in the absence of harmonin by the scaffold proteins SANS (USH1G) and whirlin (USH2D). Immunoelectron microscopic anal…
MPP1 links the Usher protein network and the Crumbs protein complex in the retina.
2007
Contains fulltext : 53571.pdf (Publisher’s version ) (Closed access) The highly ordered distribution of neurons is an essential feature of a functional mammalian retina. Disruptions in the apico-basal polarity complexes at the outer limiting membrane (OLM) of the retina are associated with retinal patterning defects in vertebrates. We have analyzed the binding repertoire of MPP5/Pals1, a key member of the apico-basal Crumbs polarity complex, that has functionally conserved counterparts in zebrafish (nagie oko) and Drosophila (Stardust). We show that MPP5 interacts with its MAGUK family member MPP1/p55 at the OLM. Mechanistically, this interaction involves heterodimerization of both MAGUK mo…
Small-Scale Sport Events and Local Community Perceptions
2020
With issues related to overtourism and, more specifically, tourismphobia, the impacts of any tourism-related activities are being scrutinised. Events falling under this category are therefore being scrutinised. Community events having been hailed to contribute to bridge the gap between locals and visitors, this chapter is going to look at small scale events and, more specifically, community sport event in Winchester (UK). Research carried by Seraphin et al. provided evidence that locals are overall very supportive of events going on in the city. That said, the research did not look at types of events, but events overall. This chapter is therefore going to provide a close up on a specific ty…
A Mlp-Based Digit And Uppercase Characters Recognition System
1997
A simple software solution for digit and uppercase handwritten characters recognition is presented. The proposed solution is based on a two-layer Multi Layer Perceptron (MLP) trained by a conjugate gradient descent (CGD) optimization algorithm. This neural network is embedded in a software tool for automatic processing of forms achieved using a scanner. The chosen solutions allow us to obtain good results both in terms of recognition rate and speed. In the paper are fully described design details and experimental results.
Meta-analysis of time perception and temporal processing in schizophrenia: Differential effects on precision and accuracy
2016
Numerous studies have reported that time perception and temporal processing are impaired in schizophrenia. In a meta-analytical review, we differentiate between time perception (judgments of time intervals) and basic temporal processing (e.g., judgments of temporal order) as well as between effects on accuracy (deviation of estimates from the veridical value) and precision (variability of judgments). In a meta-regression approach, we also included the specific tasks and the different time interval ranges as covariates. We considered 68 publications of the past 65years, and meta-analyzed data from 957 patients with schizophrenia and 1060 healthy control participants. Independent of tasks and…
Psychometric analysis of the Scale of Teacher's Perception of School Adjustment (PROF-A)
2015
La percepción del profesor del ajuste escolar de sus alumnos puede ser un importante indicador de su bienestar psicosocial y aportar información útil para el desarrollo de intervenciones encaminadas a mejorar su ajuste psicosocial. No obstante, para ello es fundamental considerar dentro del ajuste escolar no sólo el rendimiento académico del alumno sino también su nivel de integración social en el aula, la calidad de su relación con el profesor y el grado de implicación familiar en su educación. El objetivo de esta investigación es aportar un instrumento fiable para una medición completa del ajuste escolar y analizar su relación con dos importantes indicadores de ajuste psicosocial, el auto…
Clumsiness in Adolescence: Educational, Motor, and Social Outcomes of Motor Delay Detected at 5 Years
1994
This paper reports the follow-up at age 15 of a group of children who were diagnosed at age 5 as having delayed motor development. The group of children who were clumsy and the control group still differed in motor performance 10 years later: 46% of the members of the early motor delay group were classified as different from the control group on motor and perceptual tasks. The remainder made up an intermediate group that could not be clearly distinguished from the other groups. Adolescents with stable motor problems had fewer social hobbies and pastimes and had lower academic ambitions for their future than the controls, although the lower academic ambitions also reflect their lower academi…
Gli strumenti di monitoraggio e controllo e l’analisi quali-quantitativa dei dati sulla percezione del cyber-bullismo da parte degli insegnanti
2019
In the last ten years it happens less frequently to hear teachers talk about "pranks" when debating about the trend that shows a small number of teenagers and very young students, to put aggressive, violent discriminating, and, in general, victimizing behaviors are taking place. At least, we register this trend in the perception of the teachers we interviewed. It is certainly a sign, or even a consequence, of the fact that the entire educational institution, from the top management to the teachers, for over twenty years now, has become aware not only of the fact that that weren’t "pranks", but seriously aggressive behaviors, but also of the fact that, in addition to pro-sociality and non-ag…
A multinational study exploring adolescent perception of school climate and mental health.
2021
School climate is a topic of increasing importance internationally. The current study investigated the established measurement invariance of an eight-factor school climate scale using a multinational sample of secondary students. School climate factor means across 14 international groups were compared and findings on the association between school climate factors and mental health were also investigated. Findings, from this study, illustrate several cross-national similarities regarding the ways in which secondary students perceive school climate and the influence of school climate on student mental health. These findings can support school psychologists' efforts to identify strategies and …
