Contactless Respiration Monitoring in Real-Time via a Video Camera

Until today, vital signs monitoring in neonatal intensive care units (NICUs) is based on wired sensors, known to cause discomfort and false alarms. In view of overcoming such issues we investigate a contactless method for respiration monitoring by means of ...

Tomographic in vivo microscopy for the study of lung physiology at the alveolar level

Goran Lovric, Marco Stampanoni

Lungs represent the essential part of the mammalian respiratory system, which is reflected in the fact that lung failure still is one of the leading causes of morbidity and mortality worldwide. Establishing the connection between macroscopic observations o ...

Probing whole-stream metabolism: influence of spatial heterogeneity on rate estimates

Janine Rüegg

Whole-stream metabolism has been estimated by measuring in-stream oxygen (O2) concentrations since the method was introduced over 50 years ago. However, the influence of measurement location and estimation method on metabolism rates is understudied. We ...

Automated computer-assisted quantitative analysis of intact murine lungs at the alveolar scale

Goran Lovric, Marco Stampanoni

Using state-of-the-art X-ray tomographic microscopy we can image lung tissue in three dimensions in intact animals down to a micrometer precision. The structural complexity and hierarchical branching scheme of the lung at this level of details, however, re ...

Effect of PpIX photoproducts formation on pO2 measurement by time-resolved delayed fluorescence spectroscopy of PpIX in solution and in vivo

Georges Wagnières, Emmanuel Louis Arthur Gerelli, Matthieu Philippe Emmanuel Zellweger, Veronika Huntosova

The measurement of Protoporphyrin IX delayed fluorescence lifetime is a minimally invasive method for monitoring the levels of oxygen in cells and tissues. The excitation of Protoporphyrin IX during this measurement can lead to the formation of photoproduc ...

A screening-based platform for the assessment of cellular respiration in Caenorhabditis elegans

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper

Mitochondrial dysfunction is at the core of many diseases ranging from inherited metabolic diseases to common conditions that are associated with aging. Although associations between aging and mitochondrial function have been identified using mammalian mod ...

Dehalobacter – a genus of anaerobic bacteria dedicated to organohalide degradation

Christof Holliger, Julien Maillard

Abstract The genus Dehalobacter embraces bacterial populations that seem to exclusively degrade organohalides. All isolates in pure culture and highly enriched strains are obligate organohalide-respiring bacteria that use hydrogen as energy and electron so ...

Mechanistic Studies on the Stereoselectivity of the Serotonin 5-HT1A Receptor

Horst Vogel, Shuguang Yuan

G-protein-coupled receptors (GPCRs) are involved in a wide range of physiological processes, and they have attracted considerable attention as important targets for developing new medicines. A central and largely unresolved question in drug discovery, whic ...

Portable oxidative stress sensor: Dynamic and non-invasive measurements of extracellular H2O2 released by algae

Olivier Martin, Christian Santschi, Volodymyr Koman

Reactive oxygen species (ROS) generated by aerobic organisms are essential for physiological processes such as cell signaling, apoptosis, immune defense and oxidative stress mechanisms. Unbalanced oxidant/antioxidant budgets are involved in many diseases a ...
