In vitro-transfusional model for red-blood-cell study: the advantage of lowering hematocrit
Gerardo Turcatti, David Crettaz, Michel Prudent, Manon Sandra Bardyn
Background - Thequalityof red blood cells (RBCs) stored in red cell concentrates (RCCs) is influenced by processing, storage and donor characteristics, and can have a clinical impact on transfused patients. To evaluate RBC properties and their potential im ...
Simtipro Srl2023Image- and Fluorescence-Based Test Shows Oxidant-Dependent Damages in Red Blood Cells and Enables Screening of Potential Protective Molecules
Gerardo Turcatti, Benjamin Rappaz, David Crettaz, 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 s ...
2021Rhesus Blood Typing within a Few Seconds by Packing-Enhanced Nanoscattering on Individual Erythrocytes
Aleksandra Radenovic, Sebastian James Davis, Po-Ling Chang
A method for the ABO and Rhesus (Rh) blood group typing from individual erythrocytes is proposed in this study. Blood-group-specific antibodies immobilized to gold nanoparticles (BG-AuNP) were utilized for the identification of blood groups from individual ...
AMER CHEMICAL SOC2021Inhibition of influenza virus activity by the bovine seminal plasma protein PDC-109
A number of viruses causing sexually transmissible diseases are transmitted via mammalian seminal plasma. Several components of seminal plasma have been shown to influence those viruses and their physiological impact. To unravel whether components of semin ...
SPRINGER2019Identification of Oxidative Stress in Red Blood Cells with Nanoscale Chemical Resolution by Infrared Nanospectroscopy
Giovanni Dietler, Giovanni Longo, Francesco Simone Ruggeri
During their lifespan, Red blood cells (RBC), due to their inability to self-replicate, undergo an ageing degradation phenomenon. This pathway, both in vitro and in vivo, consists of a series of chemical and morphological modifications, which include devia ...
2018Quantification 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 ...
OPTICAL SOC AMER2018Erythrocyte's aging in microgravity highlights how environmental stimuli shape metabolism and morphology
Giovanni Dietler, Giovanni Longo
The determination of the function of cells in zero-gravity conditions is a subject of interest in many different research fields. Due to their metabolic unicity, the characterization of the behaviour of erythrocytes maintained in prolonged microgravity con ...
2018Automated tracking of temporal displacements of a red blood cell obtained by time-lapse digital holographic microscopy
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 ...
