Body composition-derived BMI cut-offs for overweight and obesity in ethnic Indian and Creole urban children of Mauritius

Ramuth, Harris ; Hunma, Sadhna ; Ramessur, Vinaysing ; Ramuth, Magalutcheemee ; Monnard, Cathriona ; Montani, Jean-Pierre ; Schutz, Yves ; Joonas, Noorjehan ; Dulloo, Abdul G.

In: British Journal of Nutrition, 2020, vol. 124, no. 5, p. 481–492

It is increasingly recognised that the use of BMI cut-off points for diagnosing obesity (OB) and proxy measures for body fatness in a given population needs to take into account the potential impact of ethnicity on the BMI–fat % relationship in order to avoid adiposity status misclassification. This relationship was studied here in 377 Mauritian schoolchildren (200 boys and 177 girls, aged...

Social (un-)learning and the legitimization of marginalized knowledge: How a new community of practice tries to ‘kick the grain habit’ in ruminant livestock farming

Vetter, Thomas

In: Journal of Rural Studies, 2020, vol. 79, p. 11-23

This paper presents a qualitative case study analysis of the Pasture-Fed Livestock Association (PFLA), which seeks to ‘kick the grain habit’ in ruminant farming by promoting and certifying purely pasture-fed production systems. Reading through a social learning perspective, the article first traces back how this association has become established as a new and distinct community of practice...

VAPYRIN-like is required for development of the moss Physcomitrella patens

Rathgeb, Ursina ; Chen, Min ; Buron, Flavien ; Feddermann, Nadja ; Schorderet, Martine ; Raisin, Axelle ; Häberli, Gabrielle-Yasymi ; Marc-Martin, Sophie ; Keller, Jean ; Delaux, Pierre-Marc ; Schaefer, Didier G. ; Reinhardt, Didier

In: Development, 2020, vol. 147, no. 11, p. dev184762

The VAPYRIN (VPY) gene in Medicago truncatula and Petunia hybrida is required for arbuscular mycorrhizal (AM) symbiosis. The moss Physcomitrella patens has a close homolog (VPY-like, VPYL), although it does not form AM. Here, we explore the phylogeny of VPY and VPYL in land plants, and study the expression and developmental function of VPYL in P. patens. We show that VPYL is expressed ...

New material of “Eurysternidae” (Thalassochelydia, Pan-Cryptodira) from the Kimmeridgian of the Swiss Jura Mountains

Püntener, Christian ; Anquetin, Jérémy ; Billon-Bruyat, Jean-Paul

In: Palaeovertebrata, 2020, vol. 43, no. 1, p. e2

The region of Porrentruy (Swiss Jura Mountains) is known for its rich and diverse assemblage of Late Jurassic coastal marine turtles (Thalassochelydia). Dominated by the “Plesiochelyidae”, this assemblage also includes representatives of the two other thalassochelydian groups, the “Thalassemydidae” and “Eurysternidae.” In this study, we present new shell-based material from Porrentruy...

Treating the Gibbs phenomenon in barycentric rational interpolation and approximation via the S-Gibbs algorithm

Berrut, Jean-Paul ; Marchi, S. De ; Elefante, Giacomo ; Marchetti, F.

In: Applied Mathematics Letters, 2020, vol. 103, p. 106196

In this work, we extend the so-called mapped bases or fake nodes approach to the barycentric rational interpolation of Floater–Hormann and to AAA approximants. More precisely, we focus on the reconstruction of discontinuous functions by the S-Gibbs algorithm introduced in De Marchi et al. (2020). Numerical tests show that it yields an accurate approximation of discontinuous functions.

Impact of an intra-abdominal cooling device during open kidney transplantation in pigs

Longchamp, Alban ; Meier, Raphael P. H. ; Colucci, Nicola ; Balaphas, Alexandre ; Orci, Lorenzo A. ; Nastasi, Antonio ; Longchamp, Grgoire ; Moll, Solange ; Klauser, Antoine ; Pascual, Manuel ; Lazeyras, Franois ; Corpataux, Jean-Marc ; Bühler, Leo

In: Swiss Medical Weekly, 2019, vol. 149, no. 5152, p. -

Transplantation of kidneys from deceased donors is still associated with a high rate of postoperative renal dysfunction. During implantation into the recipient, the kidney rewarms. This second warm ischaemia time, which is not monitored, is harmful especially if prolonged. We recently developed an intra-abdominal cooling device that efficiently prevents kidney rewarming during robotic...

LCO receptors involved in arbuscular mycorrhiza are functional for rhizobia perception in legumes

Girardin, Ariane ; Wang, Tongming ; Ding, Yi ; Keller, Jean ; Buendia, Luis ; Gaston, Mégane ; Ribeyre, Camille ; Gasciolli, Virginie ; Auriac, Marie-Christine ; Vernié, Tatiana ; Bendahmane, Abdelhafid ; Ried, Martina Katharina ; Parniske, Martin ; Morel, Patrice ; Vandenbussche, Michiel ; Schorderet, Martine ; Reinhardt, Didier ; Delaux, Pierre-Marc ; Bono, Jean-Jacques ; Lefebvre, Benoit

In: Current Biology, 2019, vol. 29, no. 24, p. 4249-4259.e5

Bacterial lipo-chitooligosaccharides (LCOs) are key mediators of the nitrogen-fixing root nodule symbiosis (RNS) in legumes. The isolation of LCOs from arbuscular mycorrhizal fungi suggested that LCOs are also signaling molecules in arbuscular mycorrhiza (AM). However, the corresponding plant receptors have remained uncharacterized. Here we show that petunia and tomato mutants in the LysM ...

A biologically-inspired model to predict perceived visual speed as a function of the stimulated portion of the visual field

Solari, Fabio ; Caramenti, Martina ; Chessa, Manuela ; Pretto, Paolo ; Bülthoff, Heinrich H. ; Bresciani, Jean-Pierre

In: Frontiers in Neural Circuits, 2019, vol. 13, p. -

Spatial orientation relies on a representation of the position and orientation of the body relative to the surrounding environment. When navigating in the environment, this representation must be constantly updated taking into account the direction, speed, and amplitude of body motion. Visual information plays an important role in this updating process, notably via optical flow. Here, we...
