Non-Canonical Roles of Cytosolic Phosphoenolpyruvate Carboxykinase in Small Intestine Metabolism
… perfusion model, isolated enterocytes, 13C stable isotope tracers, GC-MS, LC-MSMS, 13C NMR spectroscopy, and mathematical modeling. The functions of PEPCK in small intestine enterocytes largely recapitulate known roles in other tissues. Although, intestinal gluconeogenesis was ablated in the …

Mercury methylation potentials in sediments an ancient cypress wetland using species-specific isotope dilution-GC-ICP-MS: Analytical method development and the effect of sorbent amendments
… Unlike AAS, the ICP-MS is capable of individual isotope measurements allowing for accurate quantitation by isotope dilution mass spectrometry (IDMS) and for isotope tracer experiments. The method was validated using certified reference materials including sediment (NIST 2709), leaves (NIST 1547), …

Water Transport in the Vadose Zone and Hydrological Processes in Soil-Plant-Atmosphere Continuum (SPAC) in West Texas, USA
… of meteorological and soil water data, isotope tracers, numerical simulations, and remote sensing at a natural rangeland in West Texas. Possible sources of atmospheric moisture in west Texas were studied by the isotope tracers at different seasons and weather conditions. The summer …

Preliminary investigations for studying the effects of low carbohydrate high fat diets on gluconeogenesis in type 2 diabetes patients
… 2 (Chapter 3 of this thesis) piloted the use of stable isotope tracers for the quantification of endogenous glucose production and gluconeogenesis in the early postabsorptive state (5 hours after a meal). For methodological reasons, prior investigations have usually measured gluconeogenesis after …

An integrated approach to understanding the metabolic rewiring of cancer cells
… of metabolic engineering, most notably stable isotope tracers, can be used to study metabolism in cancer cells. Next, using a published account of hybridoma composition, we analyzed the metabolic requirements of proliferation through reducing mammalian cell biomass needs to a small …
