Spatially-Resolved Eigenmode Decomposition of Red Blood Cells Membrane Fluctuations Questions the Role of ATP in Flickering

Pierre Magistretti, Dimitri Nestor Alice Van De Ville, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Daniel Boss, Annick Hoffmann

Red blood cells (RBCs) present unique reversible shape deformability, essential for both function and survival, resulting notably in cell membrane fluctuations (CMF). These CMF have been subject of many studies in order to obtain a better understanding of ...

Detecting particles flowing through interdigitated 3D microelectrodes

Carlotta Guiducci, Enrico Accastelli, Samuel Kilchenmann, Elena Bianchi, Enrica Rollo

Counting cells in a large microchannel remains challenging and is particularly critical for in vitro assays, such as cell adhesion assays. This paper addresses this issue, by presenting the development of interdigitated three-dimensional electrodes, which ...

Automated statistical quantification of three-dimensional morphology and mean corpuscular hemoglobin of multiple red blood cells

Pierre Marquet, Daniel Boss

In this paper, we present an automated approach to quantify information about three-dimensional (3D) morphology, hemoglobin content and density of mature red blood cells (RBCs) using off-axis digital holographic microscopy (DHM) and statistical algorithms. ...

Multiscale Hemodynamics Using GPU Clusters

Efthimios Kaxiras

The parallel implementation of MUPHY, a concurrent multiscale code for large-scale hemodynamic simulations in anatomically realistic geometries, for multi-GPU platforms is presented. Performance tests show excellent results, with a nearly linear parallel s ...

Design of a blood pump for a wearable artificial kidney device

Yves Perriard, Miroslav Markovic, Michaël Rapin

The aim of a European project Nephron+ is design of a wearable artificial kidney device (WAKD). This paper is focused on design of the corresponding ultralow-hemolysis continuous-operation blood pump. Accurate specifications and operating principle of the ...

Continuous arterial spin labeling of mouse cerebral blood flow using an actively-detuned two-coil system at 9.4T

Rolf Gruetter, Hongxia Lei, Yves Pilloud

Among numerous magnetic resonance imaging (MRI) techniques, perfusion MRI provides insight into the passage of blood through the brain's vascular network non-invasively. Studying disease models and transgenic mice would intrinsically help understanding the ...

Increase of arginase activity in old apolipoprotein-E deficient mice under Western diet associated with changes in neurovascular unit

Rafaela Fernandes Da Silva, Jean-Christophe Copin

Aging and atherosclerosis are well-recognized risk factors for cardiac and neurovascular diseases. The Apolipoprotein E deficient (ApoE-/-) mouse on a high-fat diet is a classical model of atherosclerosis, characterized by the presence of atherosclerotic p ...

Early Cell Death Detection with Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Nicolas Pavillon, Pierre Marquet, Pascal Jourdain, Corinne Moratal

Background: Digital holography provides a non-invasive measurement of the quantitative phase shifts induced by cells in culture, which can be related to cell volume changes. It has been shown previously that regulation of cell volume, in particular as it r ...

Cell viability assessment by flow cytometry using yeast as cell model

Philippe Renaud, Niccolo Piacentini, Raphaël Tornay, Nina Buffi

This paper reports the new combination of cell sorting and counting capabilities on a single device. Most state-of-the-art devices combining these technologies use optical techniques requiring complicated experimental setups and labeled samples. The use of ...

Separation of platelets from other blood cells in continuous-flow by dielectrophoresis field-flow-fractionation

Philippe Renaud, Niccolo Piacentini, Raphaël Tornay

We present a microfluidic device capable of separating platelets from other blood cells in continuous flow using dielectrophoresis field-flow-fractionation. The use of hydrodynamic focusing in combination with the application of a dielectrophoretic force a ...
