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 ...

SABRE: Chemical kinetics and spin dynamics of the formation of hyperpolarization.

Progress in nuclear magnetic resonance spectroscopy, 2019
In this review, we present the physical principles of the SABRE (Signal Amplification By Reversible Exchange) method. SABRE is a promising hyperpolarization technique that enhances NMR signals by transferring spin order from parahydrogen (an isomer of ...

Hyperpolarized 13Carbon MR

Current Pharmaceutical Biotechnology, 2010
Hyperpolarized (HP) (13)C labeled compounds can be used as MR contrast agents to investigate metabolic pathways in vivo in almost real time. To date, a high proportion of reported studies have utilized HP 1-(13)C pyruvate to investigate intracellular metabolism in tumors and other tissues. The long T(1) relaxation time of the carboxylate carbon enables

ENDOTHELIUM‐DERIVED HYPERPOLARIZING FACTOR

Clinical and Experimental Pharmacology and Physiology, 1996
SUMMARY1. Not all endothelium‐dependent relaxation can be full explained by the release of either nitric oxide (NO) and/or prostacyclin. Another unidentified substance(s) that hyperpolarizes the underlying vascular smooth muscle cells (endothelium‐derived hyperpolarizing factor; EDHF) contributes to endothelium‐dependent relaxations.2. In blood vessels

Endothelium-Derived Hyperpolarizing Factor

Journal of Vascular Research, 1990
Although nitric oxide appears to be the major endothelium-derived relaxing factor (EDRF), it cannot explain all endothelium-dependent responses of isolated arteries. Thus, acetylcholine causes an endothelium-dependent, transient hyperpolarization, which is due to the release from the endothelial cells of a diffusible substance (endothelium-derived ...
