Synthesis of Methacetin-Methoxy-13C and its Analogue

Journal 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-

About the use of 13C-13C NOESY in bioinorganic chemistry

Journal of Inorganic Biochemistry, 2019
Herein we present examples of the application of the 13C-13C Nuclear Overhauser Effect Spectroscopy (NOESY) experiment to the study of metalloproteins and we critically discuss the advantages and drawbacks of the method as a function of the molecular size of the investigated systems.

Multi-criteria decision making in civil engineering. Part II – applications

Engineering Structures and Technologies, 2016
The first part of the paper shortly presented developments of multi-criteria decision making (MCDM) methods and general data about their use in civil engineering, i.e. distribution by years, countries, authors and journals (Zavadskas et al. 2015).

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

Petroleum 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.

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

Hepatology 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.

Clustering in 13C [PDF]

EPJ Web of Conferences
Measurement was conducted at the INFN-LNL, employing a Tandem accelerator to achieve a 95 MeV 14N beam focused on 10B target (201 µg/cm²) with the aim to explore the cluster structures of light carbon isotopes.

Variable responses of the soil microbial biomass to trace concentrations of 13C-labelled glucose, using 13C-PLFA analysis

, 2010
13C-labelled glucose was applied to arable (Broadbalk NPK) and permanent grassland (Woburn Grassland) soils to investigate the response of the soil microbial biomass (SMB) to carbon (C) applied at trace concentrations.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Cytosine ribose flexibility in DNA : a combined NMR 13C spin relaxation and molecular dynamics simulation study [PDF]

, 2008
Using (13)C spin relaxation NMR in combination with molecular dynamic (MD) simulations, we characterized internal motions within double-stranded DNA on the pico- to nano-second time scale.
