using15N isotope tracing and N2O isotopocules methods. Next, employing13C-DNA stable isotope probing (DNA-SIP) and sequencing of amplicons and metagenomes, we identify active nitrifier communities. Finally, we reveal the potential metabolic differences of these active nitrifiers between the plastispher...
NMR spectroscopy using 13C-isotope labelling, metabolomic and transcriptomic analyses identified a complete phytate degradation pathway in M. jalaludinii, including production of the intermediate Ins(2)P/myo-inositol. The major end product, 3-hydroxypropionate, was converted into propionate via a ...
(13)C stable isotope-labeled FA mixture(IFA-DM).The FA composition of adipocytes was analyzed by gas chromatography-mass spectrometry and gas chromatography-isotope ratio mass spectrometry.Quantitative PCR and western blotting were employed to detect expression of adipogenic genes in 3T3-L1 adipocytes ...
Lymph node metastasis (LNM) is recognized as an important factor in the progression of tumor malignancy. It is required to discover molecular markers for the prediction of LNM in gastric cancers (GCs).An isotope coded affinity tag (ICAT) method and mass spectrometry were used for the quantitativ...

After an overnight fast, all of them underwent ABT using 25 to 150 mg 13C-acetate. Breath samples were obtained at baseline and then every 10 minutes for 2 hours. The 13CO2 to 12CO2 ratio in breath samples was analysed by isotope ratio mass spectrometry. Data are expressed as follows: ...

We find significant variations in the 12CO/13CO intensity ratios and consequently in the abundance ratios. The average CO isotope abundance ratio is at least a factor three lower in the shell (~19) than that in the present-day (60). Additionally, variations in the ratio of more than an ...
