Quantification of stored red blood cell fluctuations by time-lapse holographic cell imaging

Gerardo Turcatti, Benjamin Rappaz, Pierre Marquet, Michel Prudent, Manon Sandra Bardyn

We propose methods to quantitatively calculate the fluctuation rate of red blood cells with nanometric axial and millisecond temporal sensitivity at the single-cell level by using time-lapse holographic cell imaging. For this quantitative analysis, cell me ...

Permeability and capillary effects in a channel-wise non-crimp fabric

Véronique Michaud, Damiano Salvatori, Baris Çaglar, Helena Luisa Teixido Pedarros

Flow properties are investigated for a non-crimp glass fabric with large meso-channels designed for high-permeability, as compared to glass twill woven fabric. Saturated and unsaturated permeability are measured through in-plane, unidirectional, constant-p ...

Image-Derived Input Function from the Vena Cava for 18F-FDG PET Studies in Rats and Mice

Rolf Gruetter, Bernard Lanz, Carole Poitry-Yamate

Measurement of arterial input function is a restrictive aspect for quantitative 18F-FDG PET studies in rodents because of their small total blood volume and the related difficulties in withdrawing blood. METHODS: In the present study, we took advantage of ...

Translation of biomechanical concepts in bone tissue engineering: from animal study to revision knee arthroplasty

Dominique Pioletti, Alexandre Terrier, Brigitte Jolles-Haeberli, Alireza Roshan Ghias

Bone defects in revision knee arthroplasty (RKA) are often located in load-bearing regions. The goal of this study was to determine if a physiologic load could be used as an in situ osteogenic signal to the scaffolds filling the bone defects. In order to a ...

Flow simulation and hemolysis modeling for a blood centrifuge device

Mark Sawley, Michel Deville, Patric Hagmann

A common blood separation technique is to accelerate the sedimentation of blood constituents by centrifugation and then collect these constituents separately. When subjected to conditions of excessive stress, hemolysis can however occur, whereby the membra ...

Measurement of absolute cell volume, osmotic membrane water permeability, and refractive index of transmembrane water and solute flux by digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Pascal Jourdain, Daniel Boss

A dual-wavelength digital holographic microscope to measure absolute volume of living cells is proposed. The optical setup allows us to reconstruct two quantitative phase contrast images at two different wavelengths from a single hologram acquisition. When ...

Theoretical bounds for the influence of tissue-level ductility on the apparent-level strength of human trabecular bone

Frédéric Edouard Juillard

The role of tissue-level post-yield behavior on the apparent-level strength of trabecular bone is a potentially important aspect of bone quality. To gain insight into this issue, we compared the apparent-level strength of trabecular bone for the hypothetic ...

Significant Molecular and Systemic Adaptations after Repeated Sprint Training in Hypoxia

Jean-Marc Vesin, Grégoire Millet

While intermittent hypoxic training (IHT) has been reported to evoke cellular responses via hypoxia inducible factors (HIFs) but without substantial performance benefits in endurance athletes, we hypothesized that repeated sprint training in hypoxia could ...

Quantitative Measurement of absolute cell volume and intracellular integral refractive index (RI) with Dual-wavelength Digital Holographic Microscopy (DHM)

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Daniel Boss

Quantitative Phase Imaging techniques including DHM have been applied recently in the field of cell imaging to monitor and quantify non-invasively dynamic cellular processes modifying cell morphology and/or content. Concretely, the DHM phase signal is high ...

One- and two-dimensional UVP velocity sampling in a cuboidal basin subject to in- and outflow sequences

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of an experimental study on the influence of in- and outflow sequences on flow patterns and suspended sediment behavior in reservoirs, flow fields and inflowing jet were sampled by Ultrasonic Velocity Profilers (UVP). The laboratory set-up ...
