To demonstrate the feasibility of using DNP hyperpolarized [1-(13)C]-pyruvate to measure early response to temozolomide (TMZ) therapy using an orthotopic human glioblastoma xenograft model. Twenty athymic rats with intracranial implantation of human glioblastoma cells were divided into two groups: one

Hyperpolarized (13)C magnetic resonance spectroscopy provides a unique opportunity to detect real-time metabolic fluxes as a means to measure metabolic treatment responses in vivo. Here, we show that pharmacologic inhibition of lactate dehydrogenase-A suppressed the conversion of hyperpolarized (13)C-pyruvate to

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.
