Image- and Fluorescence-Based Test Shows Oxidant-Dependent Damages in Red Blood Cells and Enables Screening of Potential Protective Molecules

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

An increase of oxygen saturation within blood bags and metabolic dysregulation occur during storage of red blood cells (RBCs). It leads to the gradual exhaustion of RBC antioxidant protective system and, consequently, to a deleterious state of oxidative st ...

Inkjet Printed Carbon Nanotube Electrodes for Measuring Pyocyaninand Uric Acid in a Wound Fluid Simulant and Culture Media

Hubert Girault, Andreas Stephan Lesch, Milica Jovic

Polyacrylamide-coated, carbon nanotube (PA/CNT)electrodes were prepared by an ink-jet printing process and used to measure pyocyanin and uric acid in a wound fluid simulant at 37 oC.These two moleculesare potential indicators of infection and therefore the ...

The antioxidant capacity of erythrocyte concentrates is increased during the first week of storage and correlated with the uric acid level

Hubert Girault, Fernando Cortes Salazar, Andreas Stephan Lesch, Niels Erik Lion, Michel Prudent, Sunny Isaïe Maye, Manon Sandra Bardyn

Background and Objectives: Red blood cells (RBCs) suffer from lesions during cold storage, depending in part on their ability to counterbalance oxidative stress by activating their antioxidant defence. The aim of this study was to monitor the antioxidant p ...

A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Puppo

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists o ...

Antioxidant Assay Based on Quenching of Photocatalytically Generated Reactive Oxygen Species

Hubert Girault, Mohamad Hojeij

A method based on photogeneration of OH radicals in water from TiO2 nanoparticles was developed to study the kinetics of oxidation of organic molecules which were used as biological antioxidants. The kinetics of oxidation of terephthalic acid as a referenc ...

An Innovative System of Membranes for the Monitoring of Endogenous and Exogenous Metabolites

Giovanni De Micheli, Sandro Carrara, Camilla Baj-Rossi, Seyedeh Sara Ghoreishizadeh

The development of a low-cost, robust, and versatile biosensors for the rapid detection of endogenous and exogenous metabolites in small animals is of great interest for health-care, pharmaceuticals, and in translational medicine. This work presents a comp ...

Efficient voltammetric discrimination of free bilirubin from uric acid and ascorbic acid by a CVD nanographite-based microelectrode

Giovanni De Micheli, László Forró, Sandro Carrara, Arnaud Magrez, Irene Taurino

We report a novel electrochemical sensor based on nanographite grown on platinum microelectrodes for the determination of bilirubin in the presence of normal concentrations of albumin. The albumin is a protein with an intrinsic ability to bind the bilirubi ...

Reaction Mechanism and Catalytic Fingerprint of Allantoin Racemase

Matteo Dal Peraro, Marco Stenta, Matteo Thomas Degiacomi, Thomas Lemmin, Christophe Bovigny

The stereospecific oxidative decomposition of urate into allantoin is the core of purine catabolism in many organisms. The spontaneous decomposition of upstream intermediates and the nonenzymatic racemization of allantoin lead to an accumulation of (R)-all ...

Highly Dynamic Cellular-Level Response of Symbiotic Coral to a Sudden Increase in Environmental Nitrogen

Anders Meibom, Duncan Thomas Lindsay Alexander, Isabelle Domart-Coulon, Christophe Kopp

Metabolic interactions with endosymbiotic photosynthetic dinoflagellate Symbiodinium spp. are fundamental to reef-building corals (Scleractinia) thriving in nutrient-poor tropical seas. Yet, detailed understanding at the single-cell level of nutrient assim ...
