Journal ArticleDOI
Oxygenation dependence of the transverse relaxation time of water protons in whole blood at high field
TL;DR: It is shown that the increase in T-1(2) with increasing blood deoxygenation arises from diffusion of water through these field gradients, which increases the volume magnetic susceptibility within the erythrocytes and thus creates local fieldgradients around these cells.
Journal ArticleDOI
Mapping of metabolites in whole animals by 31P NMR using surface coils.
TL;DR: The metabolic state of skeletal muscle and brain within intact rats is monitored using high resolution phosphorus nuclear magnetic resonance, indicating the diagnostic possibilities of the method.
Journal ArticleDOI
Observation of tissue metabolites using 31P nuclear magnetic resonance.
D. I. Hoult,Stephen J. W. Busby,D. G. Gadian,George K. Radda,Rex Edward Richards,P.J. Seeley +5 more
TL;DR: 31P NMR spectra of intact biological tissues can now be observed and the use of the spectra to study the course of reactions within the tissues is illustrated by experiments on muscle and its glycogen particle fraction.
Journal Article
Bioenergetics of intact human muscle. A 31P nuclear magnetic resonance study.
TL;DR: The dynamics of metabolic changes can now be observed with a time resolution of 10 to 60 seconds and thus disturbances in energy metabolism can be readily detected in several pathological states.
Journal ArticleDOI
Abnormal cardiac and skeletal muscle energy metabolism in patients with type 2 diabetes.
Michaela Scheuermann-Freestone,Per Lav Madsen,David Neil Manners,Andrew M. Blamire,Robin E. Buckingham,Peter Styles,George K. Radda,Stefan Neubauer,K Clarke +8 more
TL;DR: Type 2 diabetic patients with apparently normal cardiac function have impaired myocardial and skeletal muscle energy metabolism related to changes in circulating metabolic substrates.
