Russell E Ericksen et al.
Cell metabolism, 29(5), 1151-1165 (2019-01-22)
Tumors display profound changes in cellular metabolism, yet how these changes aid the development and growth of tumors is not fully understood. Here we use a multi-omic approach to examine liver carcinogenesis and regeneration, and find that progressive loss of

¹³ C MRS to Probe Brain Metabolism Using Hyperpolarized Pyruvic Acid

We present an article about the hyperpolarization of 13C labeled metabolites, especially pyruvic acid, using dynamic nuclear polarization (DNP) that allows real-time magnetic resonance spectroscopy.

MRI/MRS: Use of Isotopes in Hyperpolarization

Sigma-Aldrich.com presents an article concerning MRI/MRS and the use of isotopes in hyperpolarization.

Dynamic Nuclear Polarization

Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically enhanced NMR signals for detection.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
