MPRAGE to MP2RAGE UNI translation via generative adversarial network improves the automatic tissue and lesion segmentation in multiple sclerosis patients

Jean-Philippe Thiran, Meritxell Bach Cuadra, Thomas Yu, Cristina Granziera, Francesco La Rosa

Background and objective: Compared to the conventional magnetization-prepared rapid gradient-echo imaging (MPRAGE) MRI sequence, the specialized magnetization prepared 2 rapid acquisition gradient echoes (MP2RAGE) shows a higher brain tissue and lesion con ...

Toward catchment hydro-biogeochemical theories

Andrea Rinaldo, Paolo Benettin, Ilja van Meerveld, Li Li

Headwater catchments are the fundamental units that connect the land to the ocean. Hydrological flow and biogeochemical processes are intricately coupled, yet their respective sciences have progressed without much integration. Reaction kinetic theories tha ...

Identification of Abnormal Heart Sounds

Jean-Marc Vesin, Sasan Yazdani, Silas Schlatter, Seyyed Abbas Atyabi

As a part of 2016 Physionet/CinC callenge, this work aims at the detection of abnormal phonocardiogram (PCG) recordings. Heart sound signal analysis has been an active research topic over the past decades with various studies such as heart sound segmentati ...

Nanotopography induced contact guidance of the F11 cell line during neuronal differentiation: a neuronal model cell line for tissue scaffold development

Silvestro Micera

The F11 hybridoma, a dorsal root ganglion-derived cell line, was used to investigate the response of nociceptive sensory neurons to nanotopographical guidance cues. This established this cell line as a model of peripheral sensory neuron growth for tissue s ...

Characterization of Atrial Repolarization Alternans and Activation Time Kinetics based on Intracardiac Electrograms

Florian Jousset

Interdisciplinary collaboration between physicians and engineers is now widespread in fundamental and clinical studies, due to the increasing complexity of the physiological problems tackled, and the development of novel measurement devices and data analys ...

Decreased Excitability as a Protective Mechanism Against Repolarization Alternans-Induced Atrial Reentry

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: We recently observed in human left atrium periods of intermittent 2:1 and 1:1 atrial capture, preceded by atrial repolarization alternans (Re-ALT) during rapid pacing. It remains undetermined whether Re- ALT plays a role in preventing 1:1 atr ...

Rate-dependence of 2:1 atrial capture as a protective mechanism against atrial tachycardia-induced atrial fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

We recently observed periods of intermittent 2:1 atrial capture in the human left atrium (LA), preceded by atrial repolarization alternans during pacing-induced atrial tachycardia (PIAT). The mechanism involved in resumption of 1:1 atrial capture remains u ...

Long-term intermittent atrial tachycardia decreases activation recovery interval, flattens its kinetics and blunts its rate dependence before sustained atrial fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: We recently observed in an acute ovine model of pacing-induced atrial tachycardia (PIAT) that rapid atrial capture and fibrillatory conduction were prevented by 2:1 capture mediated by decreased excitability. We hypothesize that long-term int ...

The nodal precursor acting via activin receptors induces mesoderm by maintaining a source of its convertases and BMP4

Luca Pescatore, Felix Naef, Daniel Constam

During early mouse development, the subtilisin-like proprotein convertases (SPC) Furin and PACE4 pattern the primitive ectoderm and visceral endoderm, presumably by activating the TGFss-related Nodal precursor. Here, mutation of the SPC motif provides dire ...

A Drosophila pattern recognition receptor contains a peptidoglycan docking groove and unusual L,D-carboxypeptidase activity

Bruno Lemaitre

The Drosophila peptidoglycan recognition protein SA (PGRP-SA) is critically involved in sensing bacterial infection and activating the Toll signaling pathway, which induces the expression of specific antimicrobial peptide genes. We have determined the crys ...
