BACKGROUND & AIMS: For adequate nutritional support of critically ill children, knowledge of the patient's energy expenditure is required. Steady state measurement by a metabolic monitor are defined as resting energy expenditure and may underestimate

We describe a GC-MS and GC-c-IRMS method for the determination of labeled urea tracer enrichments in plasma as a result of combined 13C- and 15N(2)-urea infusion experiments in piglets. Urea was converted into 2-methoxypyrimidine, a stable derivative

Determination of extracellular and intracellular enrichments of [1-13C]-α-ketoisovalerate using enzymatically converted [1-13C]-valine standardization curves and gas chromatography–mass spectrometry

Autor: Willem Kulik, K. de Meer, C. Jakobs

Publikováno v: Journal of Chromatography B: Biomedical Sciences and Applications. 729:211-216

We report a validated method for the determination of extra- and intracellular [1-(13)C]-alpha-ketoisovalerate ([1-(13)C]-KIV) enrichments by gas chromatography-mass spectrometry. Standardization curves were prepared by enzymatic oxidation of [1-(13)
