Detection of Mitochondrial Dysfunction by EPR Technique in Mouse Model of Dilated Cardiomyopathy
Free Radical Biology and Medicine, 2008 Tgalphaq44 mice with targeted overexpression of activated Galphaq protein in cardiomyocytes mimic many of the phenotypic characteristics of dilated cardiomyopathy in humans. However, it is not known whether the phenotype of Tgalphaq44 mice would also involve dysfunction of cardiac mitochondria.

In vivo EPR studies of the metabolic fate of nitrosobenzene in the mouse
Magnetic Resonance in Medicine, 1994AbstractWe report the first demonstration of EPR spectroscopy to study free radical reactions in live mice and excised muscle tissue resulting from the metabolism of nitrosobenzene. A broad three‐the EPR spectrum (aN = 11.6 G) appeared in the buttocks region of a mouse place in an L‐band loop gap resonator after intramuscular or intraperitoneal ...

Stratum Corneum Lipid of Hairless Mouse Investigated by EPR
Applied Magnetic Resonance, 2011Electron paramagnetic resonance (EPR) in conjunction with a slow-tumbling simulation was utilized for examining the effect of diluted detergent-treated stratum corneum (SC) lipid structure. SC from the back of hairless mouse (HOS:HR-1) was stripped consecutively from one to three times using a glass plate coated with a cyanoacrylate resin.

Glutathione (GSH) is an important antioxidant that can protect cells under oxidative stress. Thus, a non-invasive method to measure and map the distribution of GSH in live animals is needed. To image the distribution of GSH levels in specific brain regions, a new method using electron paramagnetic resonance (EPR) imaging with a nitroxide imaging probe ...

In Vivo EPR Imaging of a Perfluoroalkyl Radical in Mouse Abdomen
Applied Magnetic Resonance, 2007Although it is thought that perfluoro-2,4-dimethyl-3-isopropyl-3-pentyl (PFR-2) is a candidate for electron paramagnetic resonance (EPR) imaging agents because of its high stability, no study has been made yet on the EPR imaging of PFR-2. In this study, EPR imaging of a phantom including PFR-2 and mice that had received PFR-2 was performed by an in ...

This article describes a method for reducing the acquisition time in three-dimensional (3D) continuous-wave electron paramagnetic resonance (CW-EPR) imaging. To visualize nitroxyl spin probes, which have a short lifetime in living organisms, the acquisition time for a data set of spectral projections should be shorter than the lifetime of the spin ...
