The effect of continuous positive airway pressure on total cerebral blood flow in healthy awake volunteers

Nikolaos Stergiopoulos, Bryn Andrew Martin

Continuous positive airway pressure (CPAP) is the gold standard treatment for obstructive sleep apnea. However, the physiologic impact of CPAP on cerebral blood flow (CBF) is not well established. Ultrasound can be used to estimate CBF, but there is no wid ...

Methods for Molecular Magnetic Resonance Imaging and Magnetic Resonance Spectroscopy using Hyperpolarized Nuclei

Riccardo Balzan

Since the introduction 10 years ago of the dissolution method, Dynamic Nuclear Polarization (DNP) became a widely applied and powerful technique to enhance nuclear magnetic resonance (NMR) signals of low naturally abundant, insensitive nuclear spins for an ...

Biomimetic Oxygen Reduction by Cofacial Porphyrins at a Liquid-Liquid Interface

Hubert Girault, Pekka Eero Peljo

Oxygen reduction catalyzed by cofacial metalloporphyrins at the 1,2-dichlorobenzene-water interface was studied with two lipophilic electron donors of similar driving force, 1,1'-dimethylferrocene (DMFc) and tetrathiafulvalene (TTF). The reaction produces ...

Triplet imaging of oxygen consumption during the contraction of a single smooth muscle cell (A7r5)

Dimitri Nestor Alice Van De Ville, Theo Lasser, Kai Johnsson, Marcel Leutenegger, Boris Hinz, Iwan Märki, Thiemo Spielmann, Aurélie Formey de Saint Louvent

The measurement of tissue and cell oxygenation is important for understanding cell metabolism. We have addressed this problem with a novel optical technique, called triplet imaging, that exploits oxygen-induced triplet lifetime changes and is compatible wi ...

Determination of local optical properties of the rat barrel cortex during neural activation: Monte-Carlo approach to light propagation

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

Spatially-spectrally-resolved reflectance measurements allow in vivo measuring the optical coefficients of absorption and scattering within the cortical tissue. This method, if applied to neural tissue during enhanced activity, could allow a straightforwar ...

Glial Energy Metabolism: A NMR Spectroscopy Perspective

Rolf Gruetter

Oxygen metabolism is uniquely compartmentalized between neurons and glia, the latter comprising about 25% of neuronal energy metabolism. The consumption of acetate and fixation of CO2 in glutamine occur in astrocytes by oxygen-dependent reactions, which po ...

Critical Heat Flux During Flow Boiling in Microchannels: A Parametric Study

John Richard Thome, Rémi Revellin

The application of flow boiling in microchannels in copper cooling elements for very high heat flux dissipation from microprocessor chips is one of the promising technologies to replace air cooling and water cooling of these units, particularly in mainfram ...

Charge storage at Pt/YSZ interface as the origin of 'permanent' electrochemical promotion of catalysis

György Foti

Tuning of the catalytic reaction rate by electric polarization of the interface between an electron conducting catalyst and an ion conducting support, called electrochemical promotion of catalysis (EPOC), is most often fully reversible. Its state-of-the-ar ...
