Microfluidic characterisation reveals broad range of SARS-CoV-2 antibody affinity in human plasma

Didier Trono, Priscilla Turelli, Marc Emmenegger

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in p ...

A functional model of adult dentate gyrus neurogenesis

Wulfram Gerstner, Olivia Gozel

In adult dentate gyrus neurogenesis, the link between maturation of newborn neurons and their function, such as behavioral pattern separation, has remained puzzling. By analyzing a theoretical model, we show that the switch from excitation to inhibition of ...

Rhesus 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 ...

Electrical Signal Modeling in Cochlear Implants. Study of Temperature and Humidity Effects

Maria-Alexandra Paun

The present paper discusses the climatic effects of humidity and temperature on cochlear implant functioning and the quality of the electrical sound signal. MATLAB Simulink simulations were prepared, offering insights into signal behavior under such climat ...

Susceptibility to infection in early life: a growing role for human genetics

Jacques Fellay, Alessandro Borghesi

The unique vulnerability to infection of newborns and young infants is generally explained by a constellation of differences between early-life immune responses and immune responses at later ages, often referred to as neonatal immune immaturity. This devel ...

Music processing in preterm and full-term newborns: A psychophysiological interaction (PPI) approach in neonatal fMRI

Dimitri Nestor Alice Van De Ville, Serafeim Loukas, François Lazeyras

Neonatal Intensive Care Units (NICU) provide special equipment designed to give life support for the increasing number of prematurely born infants and assure their survival. More recently NICU's strive to include developmentally oriented care and modulate ...

An electrochemical sensor for quantitative analysis of Rhesus D antibodies in blood

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Criscuolo, Tugba Kilic

The Hemolytic Disease of the Fetus and Newborn (HDFN), if untreated, can have severe consequences on baby’s health, eventually causing death. Prevention and diagnosis of pregnancies at risk of HDFN consists in quantitative analysis in hospital every 2-4 we ...

Intestinal NCoR1, a regulator of epithelial cell maturation, controls neonatal hyperbilirubinemia

Johan Auwerx

Severe neonatal hyperbilirubinemia (SNH) and the onset of bilirubin encephalopathy and kernicterus result in part from delayed expression of UDP-glucuronosyltransferase 1A1 (UGT1A1) and the inability to metabolize bilirubin. Although there is a good unders ...

Neonatal Group B Streptococcal Disease in Otherwise Healthy Infants: Failure of Specific Neonatal Immune Responses

Jacques Fellay, Alessandro Borghesi

Only a small proportion of newborn infants exposed to a pathogenic microorganism develop overt infection. Susceptibility to infection in preterm infants and infants with known comorbidities has a likely multifactorial origin and can be often attributed to ...

Engineered cell instructive matrices for fetal membrane healing

Martin Ehrbar

Iatrogenic preterm prelabour rupture of fetal membranes (iPPROM) occurs in 6-45% of the cases after fetoscopic procedures, posing a significant threat to fetal survival and well-being. The number of diagnostic and therapeutic prenatal interventions availab ...

Genetic engineering of cell lines using lentiviral vectors to achieve antibody secretion following encapsulated implantation

Patrick Aebischer, Bernard Schneider, Marc Moniatte, Aurélien Lathuilière

The controlled delivery of antibodies by immunoisolated bioimplants containing genetically engineered cells is an attractive and safe approach for chronic treatments. To reach therapeutic antibody levels there is a need to generate renewable cell lines, wh ...

Superior sensing performance of multi-walled carbon nanotube-based electrodes to detect unconjugated bilirubin

Giovanni De Micheli, Sandro Carrara, Irene Taurino

The direct electrochemical behaviour of bilirubin in the physio-pathological concentration range and at physio- logical pH was investigated by cyclic voltammetry. Nanostructured electrodes with a thin film of multi-walled carbon nanotubes exhibited a highe ...

TLR4- and TRIF-dependent stimulation of B lymphocytes by peptide liposomes enables T cell-independent isotype switch in mice

Pedro Miguel Nunes Pereira de Almeida Reis, Andrea Pfeifer, Marija Vukicevic, Andreas Muhs, Valérie Gafner, Anna Lucia Buccarello

Immunoglobulin class switching from IgM to IgG in response to peptides is generally T cell-dependent and vaccination in T cell-deficient individuals is inefficient. We show that a vaccine consisting of a dense array of peptides on liposomes induced peptide ...

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 ...

High-field diffusion tensor imaging characterization of cerebral white matter injury in lipopolysaccharide-exposed fetal sheep

Yohan Van de Looij, François Lazeyras

BACKGROUND: In gyrencephalic species such as sheep, precise anatomical and microstructural characterization of the consequences of fetal inflammation remains scarce. The goal of this study was to characterize changes in white matter (WM) structure using ad ...

Immunoisolated cell implants for intracerebral delivery of anti-Aß single chain Fv antibodies in the APP23 Alzheimer's mouse model

Osiris Marroquin Belaunzaran

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the elderly population. AD currently affects approximately 27 million people worldwide. A pathological hallmark of AD is the accumulation and deposition of the amyloid beta (Aβ) pe ...
