Can the odours modulate salivation? Impact of the nature of the odorant

2015

Introduction :Saliva plays numerous roles in the oral cavity, especially in digestion and taste perception. It is well admitted that tastants are effective stimuli of salivation and that the salivary response (flow and composition) depends on the nature of the tastant. However, the impact of odours on salivation is poorly known and not consensual. Odours are the first chemical signal informing about food palatability before ingestion. In this context, it is necessary to understand if the salivary secretions are modulated in function of this sensory signal. The aim of this study is to compare the salivary flow response after stimulation by different odours having different hedonic values.Mat…

Taste Bud Density and Composition of Saliva in Patients Suffering from Taste Disorders Compared to Healthy Individuals

2016

Aim: Previous studies have shown a correlation between fungiform papillae density and acuity of taste. In addition changes of salivary composition in oral sensation complaints were observed as well. Aim of this prospective investigation was to determine correlations between the fungiform papillae density, salivary composition and taste acuity of healthy individuals and patients with idiopathic taste disorders.Material & Methods: The present study was performed in 81 patients with a mean age of 58±13 years complaining of gustatory dysfunctions and groups of 20 younger (age 24±3 years) and 20 older healthy subjects (age 55±10 years).Taste perception was measured using taste strips and electro…

Biopsychosocial approach to caregiving burden: Why should we care about caregivers’ health?

2018

There are 11 million family caregivers in France and some estimates indicate that there will be 17 million in 2020.Caregiving is a source of chronic stress that requires adaptation and coping strategies.Caregiving may benefit the health of a caregiver with a positive coping style and altruistic goals.However, the caregiver's burden is frequently associated with negative effects in terms of biopsychosocial imbalance and medical conditions, with frequent anxiety and depression.The management of the caregiving burden starts with the recognition of health professionals – caregivers may benefit from consultation-liaison psychiatry and multidisciplinary medico-social strategies, in addition to co…

I Cannot Read Your Eye Expression: Suicide Attempters Have Difficulties in Interpreting Complex Social Emotions

2020

International audience; Background: The ability to differentiate emotions in social contexts is important for dealing with challenging social situations. Suicide attempters show some difficulties in emotion recognition that may result in hypersensitivity to social stress. However, other studies on the recognition of social complex emotions found that suicide attempters have similar performances as depressed non-attempters. Objectives: To investigate differences in social emotion recognition in patients with current Major Depressive Episode (MDE) with and without history of suicide attempt. Methods: Two hundred and ten patients with MDE were recruited among whom 115 had lifetime history of s…

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018…

2018

Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean dia…

Eukaryotic rRNA Modification by Yeast 5-Methylcytosine-Methyltransferases and Human Proliferation-Associated Antigen p120.

2015

International audience; Modified nucleotide 5-methylcytosine (m(5)C) is frequently present in various eukaryotic RNAs, including tRNAs, rRNAs and in other non-coding RNAs, as well as in mRNAs. RNA: m(5)C-methyltranferases (MTases) Nop2 from S. cerevisiae and human proliferation-associated nucleolar antigen p120 are both members of a protein family called Nop2/NSUN/NOL1. Protein p120 is well-known as a tumor marker which is over-expressed in various cancer tissues. Using a combination of RNA bisulfite sequencing and HPLC-MS/MS analysis, we demonstrated here that p120 displays an RNA:m(5)C-MTase activity, which restores m(5)C formation at position 2870 in domain V of 25S rRNA in a nop2 Delta …
