1H-[13C]-NMR investigation of brain energy metabolism in zebrafish: Impact of acute ethanol

open access: yesJournal of Magnetic Resonance Open, 2022
Zebrafish has emerged as an excellent model organism for understanding the biology of the central nervous system. There is limited data pertaining to neurotransmitter energetics in the zebrafish brain.

Molecular orientational dynamics of the endohedral fullerene Sc$_{3}$N@C$_{80}$ as probed by $^{13}$C and $^{45}$Sc NMR [PDF]

open access: yes, 2006
We measure 13C and 45Sc NMR lineshapes and spin-lattice relaxation times (T1) to probe the orientational dynamics of the endohedral metallofullerene Sc3N@C80.

Synthesis of Methacetin-Methoxy-13C and its Analogue

open access: yesJournal of Isotopes, 2021
In the current research on 13C-labeled compounds breath test of liver function, methacetin-methoxy-13C is the most potential substrate. To study a new method for synthesis methacetin-methoxy-13C, methanol-13C was used as the labeled material, methacetin-

13C-direct detected NMR experiments for the sequential J-based resonance assignment of RNA oligonucleotides [PDF]

open access: yes, 2010
We present here a set of 13C-direct detected NMR experiments to facilitate the resonance assignment of RNA oligonucleotides. Three experiments have been developed: (1) the (H)CC-TOCSY-experiment utilizing a virtual decoupling scheme to assign the ...

NMR chemical shifts of carbon atoms and characteristic shift ranges in the oil sample

open access: yesPetroleum Research, 2022
Application of high resolution 13C nuclear magnetic resonance (NMR) spectroscopy to characterize crude oil was demonstrated. The chemical shifts of 13C NMR functional groups that determine the composition of the oil sample were determined.

Near infrared spectroscopy of M dwarfs. IV. A preliminary survey on the carbon isotopic ratios in M dwarfs

open access: yes, 2016
Based on the medium resolution near infrared spectra of 13CO (3,1) band, carbon isotopic ratios are estimated in 48 M dwarfs, for which we had determined the carbon and oxygen abundances from CO and H2O lines, respectively. We find clear evidence for the

Assessment of Rapid Hepatic Glycogen Synthesis in Humans Using Dynamic 13C Magnetic Resonance Spectroscopy

open access: yesHepatology Communications, 2020
Carbon‐13 magnetic resonance spectroscopy (MRS) following oral intake of 13C‐labeled glucose is the gold standard for imaging glycogen metabolism in humans. However, the temporal resolution of previous studies has been >13 minutes.
