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…

Minerality in wines: mental expectations of Swiss and French consumers
2014
Today the concept of minerality in wines is omnipresent. It appears in marketing discourses, in oenological critics and commercial communication. However, there is no common agreement on a general definition. This paper aims to study the different expectations that Swiss and French consumers have about minerality. The multidimensionality of the term is reflected through stereotypes like the odor of flint, the impression of "sucking a stone", or referring to acidity or to the Terroir. Thus, the term minerality appears as a unstable concept and providing a precise definition remains consequently difficult for many consumers.
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 …
Absolute quantification of noncoding RNA by microscale thermophoresis
2019
Abstract Accurate quantification of the copy numbers of noncoding RNA has recently emerged as an urgent problem, with impact on fields such as RNA modification research, tissue differentiation, and others. Herein, we present a hybridization‐based approach that uses microscale thermophoresis (MST) as a very fast and highly precise readout to quantify, for example, single tRNA species with a turnaround time of about one hour. We developed MST to quantify the effect of tRNA toxins and of heat stress and RNA modification on single tRNA species. A comparative analysis also revealed significant differences to RNA‐Seq‐based quantification approaches, strongly suggesting a bias due to tRNA modifica…
Diversity begets diversity: A global perspective on gender equality in scientific society leadership.
2018
Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …
Etude de l’implication de l'endocytose à clathrine dans les réactions de défense déclenchées par la cryptogéine chez le tabac
2012
La cryptogéine est un éliciteur protéique des réactions de défense chez le tabac sécrété par l’oomycète Phytophthora cryptogea. Son interaction avec un récepteur encore non identifié de la membrane plasmique déclenche une cascade d’événements de signalisation qui conduisent à une reprogrammation génique, à la diffusion d’un signal conférant une résistance systémique et, ultimement, à la mort des cellules directement exposées à cet éliciteur. Notre équipe avait précédemment mis en évidence une stimulation de la formation de vésicules d’endocytose quelques minutes après l’élicitation. Des études de microscopie électronique et d’inhibition pharmacologique avait permis d’émettre l’hypothèse que…
