Brain dysmyelination and recovery assessment by noninvasive in vivo diffusion tensor magnetic resonance imaging.
Laura A. Harsan,Patrick Poulet,Blandine Guignard,Jérôme Steibel,Nathalie Parizel,Paulo Loureiro de Sousa,Nelly Boehm,Daniel Grucker,M. Said Ghandour +8 more
TL;DR: It is shown clearly that myelination and axonal changes play a role in the degree of diffusion anisotropy, because FA was significantly decreased in dysmyelinated brain.

Recovery from Chronic Demyelination by Thyroid Hormone Therapy: Myelinogenesis Induction and Assessment by Diffusion Tensor Magnetic Resonance Imaging
Laura A. Harsan,Jérôme Steibel,Anita Zaremba,Arnaud Agin,Rémy Sapin,Patrick Poulet,Blandine Guignard,Nathalie Parizel,Daniel Grucker,Nelly Boehm,Robert H. Miller,M. Said Ghandour +11 more
TL;DR: Injection of triiodothyronine (T3) hormone over a 3 week interval after cuprizone withdrawal progressively restored the normal DT-MRI phenotype accompanied by an improvement of clinical signs and remyelination, establishing a role for T3 as an inducer of oligodendrocyte progenitor cells in adult mouse brain following chronic demyelinations.

NMR relaxation rates and blood oxygenation level.
TL;DR: A linear relationship between the proton relaxation rates and the fraction of deoxyhemoglobin of circulating whole blood has been established in vitro and the Luz‐Mei‐boom relation applied to this interpulse delay dependence of R2 suggests a two‐site chemical exchange rather than a diffusion mechanism.

Left Ventricular Ejection Fraction in Obstructive Sleep Apnea: Effects of Long-term Treatment with Nasal Continuous Positive Airway Pressure
TL;DR: It is shown that long-term nasal CPAP treatment results in improved left ventricular function in OSA, and changes were not different when subgroups of medicated and unmedicated patients were considered separately.

Dynamic nuclear polarization with nitroxides dissolved in biological fluids.
Daniel Grucker,Thierry Guiberteau,Bernard Eclancher,Jacques Chambron,R Chiarelli,A. Rassat,G Subra,Bernard Gallez +7 more
TL;DR: The most widely used free radicals for dynamic nuclear polarization (DNP) experiments or related Overhauser imaging are nitroxides, and the DNP parameters in biological fluids were measured in order to provide guidelines for the design of new nitroxided, adapted to the biological applications of DNP.
