A multiscale study of the role of dynamin in the regulation of glucose uptake

Johan Auwerx, Martinus Gijs, Kristina Schoonjans, Laurent Mouchiroud, Raphaël Etienne Jean Trouillon, Keir Joe Menzies, Maria Cristina Letizia

Glucose uptake in muscle cells in response to insulin is a fundamental mechanism for metabolism. The inability of cells to mobilize the specific glucose transporter GLUT4 is believed to be at least partially accountable for diseases, like diabetes, where c ...

Changes in Heart Rate Variability Recorded in Natural Situation with T-Shirt Integrated Sensors and Level of Observed Behavioral Excitation: A Pilot Study of Patients with Intellectual Disabilities and Psychiatric Disorders

Michel Akselrod

Background: The present study investigates the possibilities of using heart rate variability (HRV) parameters as physiological markers that precede increase in observed behavioral excitation of intellectually disabled individuals. The ability to recognize ...

Swimming with a cage: low-Reynolds-number locomotion inside a droplet

François Gallaire, Lailai Zhu

Inspired by recent experiments using synthetic microswimmers to manipulate droplets, we investigate the low-Reynolds-number locomotion of a model swimmer (a spherical squirmer) encapsulated inside a droplet of a comparable size in another viscous fluid. Me ...

Optospintronics in Graphene via Proximity Coupling

Andras Kis, Oriol López Sánchez, Ahmet Avsar, Dmitrii Unuchek

The observation of micrometer size spin relaxation makes graphene a promising material for applications in spintronics requiring long-distance spin communication. However, spin dependent scatterings at the contact/graphene interfaces affect the spin inject ...

A multimodal framework for the design and the assessment of robotic-assisted treatments for motor disorders

Elvira Pirondini

Robotic devices represent an undeniable alternative method to traditional therapy. However, the clinical use of robot-assisted rehabilitation for patients with hemiplegia after stroke has been restricted for decades by i) limited functional characterisatio ...

Fluid structure interaction in straight pipelines with different anchoring conditions

Anton Schleiss, Pedro Filipe De Almeida Manso, David Ferràs Segura

This investigation aims at assessing the fluid-structure interaction (FSI) occurring during hydraulic transients in straight pipeline systems fixed to anchor blocks. A two mode 4-equation model is implemented incorporating the main interacting mechanisms: ...

Optimization of thin-film highly-compliant elastomer sensors for contractility measurement of muscle cells

Herbert Shea, Cristina Martin Olmos, Matthias Imboden, Samuel Rosset, Alexandre Poulin, Mélanie Favre, Oluwaseun Adelowo Araromi, Francesca Sorba

Test assays capable of providing quantitative characterization of the contraction of cardiac and smooth muscle cells are of great need for drug development and screening. Several methodologies have been proposed for achieving measurement of cell contractil ...

Muscle activation variability is inversely correlated with walking speed

Auke Ijspeert, Florin Dzeladini, Cole Stewart Simpson, Amandine Grappe

Individuals with motor impairments typically walk at much slower speeds than their unimpaired counter- parts, yet their gait data is still evaluated against the relatively faster gait of healthy subjects. Therefore a good understanding of unimpaired gait a ...

An agonist-antagonist pitch production model

Philip Neil Garner

Prosody is a phenomenon that is crucial for numerous fields of speech research, accenting the importance of having a robust prosody model. A class of intonation models based on the physiology of pitch pro- duction are especially attractive for their inhere ...

Intercellular ultrafast Ca2+ wave in vascular smooth muscle cells: numerical and experimental study

Jean-Jacques Meister, Niccolo Piacentini, Franck Claude Raynaud, Jairo Camilo Quijano Perez

Vascular smooth muscle cells exhibit intercellular Ca2+ waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca2+ wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave w ...
