Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset

Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this cha ...

Deep learning parametric response mapping from inspiratory chest CT scans: a new approach for small airway disease screening

Jiancheng Yang, Zhiye Wang, Jun Lu, Zhigang Li, Lin Qi, Ming Li, Bo Du, Yuxuan Sun, Ziyi Liu

Objectives Parametric response mapping (PRM) enables the evaluation of small airway disease (SAD) at the voxel level, but requires both inspiratory and expiratory chest CT scans. We hypothesize that deep learning PRM from inspiratory chest CT scans can eff ...

A Machine-Generated View of the Role of Blood Glucose Levels in the Severity of COVID-19

Henry Markram, Daniel Keller, Jay Coggan, Cyrille Pierre Henri Favreau, Mohameth François Sy, Emmanuelle Logette, Samuel Claude Kerrien, Enrico Scantamburlo, Francesco Casalegno, Anna-Kristin Kaufmann, Pierre-Alexandre Fonta

SARS-CoV-2 started spreading toward the end of 2019 causing COVID-19, a disease that reached pandemic proportions among the human population within months. The reasons for the spectrum of differences in the severity of the disease across the population, an ...

Design of a bed load and driftwood filtering dam, analysis of the phenomena and hydraulic design

Giovanni De Cesare

Flood protection often calls on to the realization of retention works for bed load as well as wood and debris flow. Certain relatively recent arrangements did not perform according to their intended function, what shows the complexity of the design and the ...

High-resolution 3D condition survey of a masonry arch bridge using Ground Penetrating Radar

Eugen Brühwiler, Alexis Kalogeropoulos

Condition surveying is essential before rehabilitation and modification of a structure. It implies information collection and analysis for structural performance evaluation. Common condition surveying often requires obstructive and invasive techniques that ...

Endoscopic low coherence topography measurement for upper airways and hollow samples

Christian Depeursinge, Nicolas Pavillon, Florian Lang, Jonas Kühn, Etienne Shaffer, Yves Delacrétaz

To evaluate the severity of airway pathologies, quantitative dimensioning of airways is of utmost importance. Endoscopic vision gives a projective image and thus no true scaling information can be directly deduced from it. In this article, an approach base ...

Endoscopic low coherence interferometry in upper airways

Christian Depeursinge, Florian Lang, Daniel Boss, Yves Delacrétaz

We introduce Endoscopic Low Coherence Interferometry to obtain topology of upper airways through commonly used rigid endoscopes. Quantitative dimensioning of upper airways pathologies is crucial to provide maximum health recovery chances, for example in or ...

Endoscopic low coherence interferometry applied to tri-dimensional contouring of upper airways

Yves Delacrétaz

This thesis presents a novel approach for optical tri-dimensional contouring, requiring only one acquisition to extract a contour depth. It is based on an interferometric setup, using a reduced coherence light source, and is fully adaptable to endoscopic p ...

PPARalpha downregulates airway inflammation induced by lipopolysaccharide in the mouse

Johan Auwerx

BACKGROUND: Inflammation is a hallmark of acute lung injury and chronic airway diseases. In chronic airway diseases, it is associated with profound tissue remodeling. Peroxisome proliferator-activated receptor-alpha (PPARalpha) is a ligand-activated transc ...

Early death due to defective neonatal lung liquid clearance in alpha-ENaC-deficient mice

Friedrich Beermann

The amiloride-sensitive epithelial sodium channel, ENaC, is a heteromultimeric protein made up of three homologous subunits (alpha, beta and gamma) (1,2). In vitro, assembly and expression of functional active sodium channels in the Xenopus oocyte is stric ...
