Protein Corona: Impact of Lymph Versus Blood in a Complex In Vitro Environment

Heinrich Hofmann, Ulrich Aschauer, Marc Moniatte, Diego Chiappe, Marijana Mionic Ebersold, Duncan Thomas Lindsay Alexander, Débora Bonvin

In biological environments, the surface of nanoparticles (NPs) are modified by protein corona (PC) that determines their biological behavior. Unfortunately, in vitro tests still give different PC than in vivo tests causing in vitro-in vivo discrepancy; hen ...

Study of cortical energy metabolism during sensory stimulation-induced brain activity by ¹³C magnetic resonance spectroscopy in vivo

Sarah Catherine Sonnay

Cerebral function is associated with high metabolic activity that is supported by continuous supply of oxygen and glucose from the blood. Coupling between brain energy metabolism and neuronal activity has been studied extensively during the past decades. N ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Michel Prudent, Niels Erik Lion, Benjamin Rappaz, Manon Sandra Bardyn, David Crettaz

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

Thiazolium carbene catalysts for the fixation of CO2 onto amines

Paul Joseph Dyson, Safak Bulut, Felix Daniel Bobbink, Mylène Soudani, Shoubhik Das

The catalytic N-formylation and N-methylation of amines using CO2 as the carbon source represents a facile and sustainable approach for the synthesis of pharmaceuticals and natural products. Herein, we describe highly effective and inexpensive thiazolium c ...

Modelling of a Dielectric Electroactive Polymer Tubular Shape Sensor for Pressure Measurements

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne

The variation of pressure of the blood is a key parameter in the development of ventricular assist device. This latter is useful in order to synchronize the behavior of the actuator with the cardiac frequency. This paper presents a sensor made of a dielect ...

Automated tracking of temporal displacements of a red blood cell obtained by time-lapse digital holographic microscopy

Benjamin Rappaz

Red blood cell (RBC) phase images that are numerically reconstructed by digital holographic microscopy (DHM) can describe the cell structure and dynamics information beneficial for a quantitative analysis of RBCs. However, RBCs investigated with time-lapse ...

Study of the influence of over-the-counter vitamin supplement intake on urine fluorescence to optimize cancer detection by fluorescence cystoscopy

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Carla Martoccia

Fluorescence cystoscopy (FC) efficiently enhances the detection and improves the therapeutic management of early bladder cancer. During an FC, about 150 ml of water is needed to inflate the bladder. The water is quickly diluted by urine which can be fluore ...
