Effective segmentation of fresh post-mortem murine lung parenchyma in phase contrast X-ray tomographic microscopy images

Goran Lovric, Marco Stampanoni

The acinus represents the functional unit of the mammalian lung. It is defined as the small tree of gas-exchanging airways, which is fed by the most distal purely conducting airway. Different hypotheses exist on how the fine structure of the acinus changes ...

Sleep Disordered Breathing During Live High-Train Low in Normobaric Versus Hypobaric Hypoxia

Jean-Marc Vesin, Sibylle Fallet, Grégoire Millet, Mattia Bertschi

The present study aimed to compare sleep disordered breathing during live high-train low (LHTL) altitude camp using normobaric hypoxia (NH) and hypobaric hypoxia (HH). Sixteen highly trained triathletes completed two 18-day LHTL camps in a crossover design ...

Sleep Apnea Detection using Features from the Respiration and the ECG recorded with Smart-Shirts

Jean-Marc Vesin, Leila Mirmohamadsadeghi, Andréa Buttu, Grégoire Millet, Sibylle Fallet

The automatic detection of sleep apnea episodes, without the need of polysomnography and outside a clinical facility, could help facilitate the diagnosis of this disorder. In this work, features to detect sleep apnea events were computed from respiration a ...

Electrical impedance tomography system based on active electrodes

Peter Seitz

Electrical impedance tomography (EIT) can image the distribution of ventilated lung tissue, and is thus a promising technology to help monitor patient breathing to help selection of mechanical ventilation parameters. Two key difficulties in EIT instrumenta ...

Dye metachromasy on titanate nanowires: sensing humidity with reversible molecular dimerization

László Forró, Arnaud Magrez, Primoz Rebernik Ribic, Endre Horvath

We report on the reversible dimerization of methylene blue (MB) on titanate nanowires. The self-organizational properties of MB on the surface of this nanostructured material studied by spectroscopic means revealed that the light absorption properties of t ...

Validation of a one-dimensional model of the systemic arterial tree

Nikolaos Stergiopoulos, Fabrice Merenda, Philippe Reymond

A distributed model of the human arterial tree including all main systemic arteries coupled to a heart model is developed. The one-dimensional (1-D) form of the momentum and continuity equations is solved numerically to obtain pressures and flows throughou ...
