Renal Purge of Hemolymphatic Lipids Prevents the Accumulation of ROS-Induced Inflammatory Oxidized Lipids and Protects Drosophila from Tissue Damage

Bruno Lemaitre, Samuel Rommelaere, Xiaoxue Li

Animals require complex metabolic and physiological adaptations to maintain the function of vital organs in response to environmental stresses and infection. Here, we found that infection or injury in Drosophila induced the excretion of hemolymphatic lipid ...

Non-invasive pulmonary artery pressure estimation by electrical impedance tomography in a controlled hypoxemia study in healthy subjects

Jean-Philippe Thiran, Mathieu Lemay, Fabian Braun, Martin Proença

Pulmonary hypertension is a hemodynamic disorder defined by an abnormal elevation of pulmonary artery pressure (PAP). Current options for measuring PAP are limited in clinical practice. The aim of this study was to evaluate if electrical impedance tomograp ...

Reactive species monitoring and their contribution for removal of textile effluent with photocatalysis under UV and visible lights: Dynamics and mechanism

Sami Rtimi

In this study, the photocatalytic activities were investigated for the treatment of Reactive Green 12 (RG 12) solution under UV and visible irradiation using Cu doped TiO2, and TiO2 impregnated on (1) cellulose and (2) UV-C activated polyester catalysts. T ...

NOS2-deficient mice with hypoxic necrotizing lung lesions predict outcomes of tuberculosis chemotherapy in humans

Stewart Cole

During active TB in humans a spectrum of pulmonary granulomas with central necrosis and hypoxia exists. BALB/c mice, predominantly used in TB drug development, do not reproduce this complex pathology thereby inaccurately predicting clinical outcome. We fou ...

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 ...

Erythropoietin Restores Long-Term Neurocognitive Function Involving Mechanisms of Neuronal Plasticity in a Model of Hyperoxia-Induced Preterm Brain Injury

Yohan Van de Looij

Cerebral white and grey matter injury is the leading cause of an adverse neurodevelopmental outcome in prematurely born infants. High oxygen concentrations have been shown to contribute to the pathogenesis of neonatal brain damage. Here, we focused on moto ...

Applications of Nanoparticles for Reactive Oxygen Species (ROS) Scavenging in Photosynthetic Systems

Ardemis Anoush Boghossian

Under aerobic conditions, excessive illumination results in the photogeneration of reactive oxygen species (ROS) responsible for protein damage and photo-inhibition during photosynthesis. We explore the effects of nanoceria (NC), a regenerative ROS scaveng ...

Repeated Double-Poling Sprint Training in Hypoxia by Competitive Cross-country Skiers

Jean-Marc Vesin, Grégoire Millet

Purpose Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasodilation, and therefore, our hypothesis was that RSH is ev ...

In vivo electrochemical corrosion study of a CoCrMo biomedical alloy in human synovial fluids

Stefano Mischler

The present study was initiated with the aim to assess the in vivo electrochemical corrosion behaviour of CoCrMo biomedical alloys in human synovial fluids in an attempt to identify possible patient or pathology specific effects. For this, electrochemical ...

Evaluation of uptake and transport of ultrasmall superparamagnetic iron oxide nanoparticles by human brain-derived endothelial cells

Heinrich Hofmann

Aim: Ultrasmall superparamagnetic iron oxide nanoparticles (USPIO-NPs) are under development for imaging and drug delivery; however, their interaction with human blood brain barrier models is not known. Materials & Methods: The uptake, reactive oxygen spec ...

Interaction of inflammation and hyperoxia in a rat model of neonatal white matter damage

Yohan Van de Looij

Intrauterine infection and inflammation are major reasons for preterm birth. The switch from placenta-mediated to lung-mediated oxygen supply during birth is associated with a sudden rise of tissue oxygen tension that amounts to relative hyperoxia in prete ...

Photocatalytic and phototoxic properties of TiO2-based nanofilaments: ESR and AFM assays

László Forró, Arnaud Magrez, Andrzej Kulik, Andrzej Sienkiewicz, Katarzyna Pierzchala

There is uncertainty in understanding of the relationship between physico-chemical parameters of nanosized titanium dioxide (nano-TiO2) and its toxicity when brought into contact with living cells. This study provides a multidisciplinary experimental insig ...
