Effect of the hydrogenation solvent in the PHIP-SAH hyperpolarization of [1-13C]pyruvate
Autor: Silvio Aime, Carla Carrera, Oksana Bondar, Francesca Reineri, Eleonora Cavallari
Publikováno v: Catalysis Today
ParaHydrogen Induced Polarization-Side Arm Hydrogenation (PHIP-SAH) is an inexpensive tool to obtain hyperpolarized pyruvate (and other metabolites) that can be applied to in vivo diagnostics, for the investigation of metabolic processes. This method

Synergies between Hyperpolarized NMR and Microfluidics: A Review
Autor: William J. Hale, Marcel Utz, James Eills
Publikováno v: Progress in Nuclear Magnetic Resonance Spectroscopy
Hyperpolarized nuclear magnetic resonance and lab-on-a-chip microfluidics are two dynamic, but until recently quite distinct, fields of research. Recent developments in both areas increased their synergistic overlap. By microfluidic integration, many

Significance Magnetic resonance imaging is hindered by inherently low sensitivity, which limits the method for the most part to observing water molecules in the body. Hyperpolarized molecules exhibit strongly enhanced MRI signals which opens the door

Parahydrogen‐Induced Polarization of Amino Acids
Autor: Pravdivtsev, Andrey N., Buntkowsky, Gerd, Duckett, Simon B., Koptyug, Igor V., Hövener, Jan‐Bernd
Publikováno v: Angewandte Chemie (International Ed. in English)
Nuclear magnetic resonance (NMR) has become a universal method for biochemical and biomedical studies, including metabolomics, proteomics, and magnetic resonance imaging (MRI). By increasing the signal of selected molecules, the hyperpolarization of

ChemPhysChem 22(24), 2526-2534 (2021). doi:10.1002/cphc.202100667
We introduce a Spin Transfer Automated Reactor (STAR) that produces continuous parahydrogen induced polarization (PHIP), which is stable for hours to days. We use the PHIP variant called signal amplification by reversible exchange (SABRE), which is p

We report on the utility of Radiofrequency Amplification by Stimulated Emission Radiation (RASER) for background-free proton detection of hyperpolarized biomolecules. We performed hyperpolarization of ≈0.3 M ethyl acetate via pairwise parahydrogen

Although hyperpolarization (HP) greatly increases the sensitivity of 13C MR, the usefulness of HP in vivo is limited by the short lifetime of HP agents. To address this limitation, we developed an echo-planar (EPI) sequence with spectral-spatial radi
