Parahydrogen‐Based Hyperpolarization for Biomedicine

Angewandte Chemie - International Edition, 2018
AbstractMagnetic resonance (MR) is one of the most versatile and useful physical effects used for human imaging, chemical analysis, and the elucidation of molecular structures. However, its full potential is rarely used, because only a small fraction of the nuclear spin ensemble is polarized, that is, aligned with the applied static magnetic field ...

Hyperpolarizing Factors

Biochemical Pharmacology, 1997
There is now overwhelming evidence for factors, other than nitric oxide (NO), that mediate endothelium-dependent vasodilation by hyperpolarizing the underlying smooth muscle via activation of Ca2+-activated K+ channels. Although the identity of endothelium-derived hyperpolarizing factor (EDHF) remains to be established, cytochrome P450 (CYP)-dependent ...

Parahydrogen‐Induced Hyperpolarization of Gases

Angewandte Chemie - International Edition, 2020
AbstractImaging of gases is a major challenge for any modality including MRI. NMR and MRI signals are directly proportional to the nuclear spin density and the degree of alignment of nuclear spins with applied static magnetic field, which is called nuclear spin polarization.

Adaptation by Hyperpolarization

Science, 1997
Adaption to external stimuli prevents us from being overwhelmed by the constant bombardment of our senses: A noxious odor, immediately repulsive, becomes hardly noticeable; after a time, the sound of traffic is no longer annoying. A report in this week's issue by Carandini and Ferster (p.
