Hyperpolarization in Medical Definition

Depolarization-induced suppression of inhibition

...opic , typically results in the influx of chloride ions into that target cell. This build-up of negative charge from the chloride ions results in the hyperpolarization of the target cell, making it less likely to fire an action potential . Accordingly, any ionic current that hyperpolarizes a cell is called an inhib...

Bruker Introduces HyperQuant™, a Unique Bench-Top NMR Reader to Quantify Hyperpolarization

At the 2008 World Molecular Imaging Congress (for details, see www.wmicmeeting.org ), Bruker BioSpin introduces HyperQuant™, a bench-top NMR reader for precisely quantifying both the magnetic hyperpolarization as well as the thermal polarization of a sample. The HyperQuant applies time-dom...

...here is a net excess in the para spin state even at room temperature and in the complete absence of a magnetic field. Under the right conditions, this hyperpolarization can be passed on to other nuclei and used to substantially boost the strength of their MRI/NMR signals by several orders of magnitude. Pines, Bouch...
