Historical and contemporary stable isotope tracer approaches to studying mammalian protein metabolism. [PDF]
Mass Spectrom Rev, 2018 Over a century ago, Frederick Soddy provided the first evidence for the existence of isotopes; elements that occupy the same position in the periodic table are essentially chemically identical but differ in mass due to a different number of neutrons ...

Physiologic requirement for iron in pregnant women, assessed using the stable isotope tracer technique [PDF]
Nutrition & Metabolism, 2020 Background Knowledge of the physiologic requirement for iron, the core index for the formulation of a dietary reference intake (DRI), is of great importance for the health of a pregnant woman and her fetus, and can help a mother accurately plan her iron ...

A novel stable isotope tracer method to simultaneously quantify skeletal muscle protein synthesis and breakdown [PDF]
Metabolism Open, 2020 Background/aims: Methodological challenges have been associated with the dynamic measurement of muscle protein breakdown (MPB), as have the measurement of both muscle protein synthesis (MPS) and MPB within the same experiment.

AccuCor2: isotope natural abundance correction for dual-isotope tracer experiments [PDF]
Laboratory Investigation, 2021 Stable isotope labeling techniques have been widely applied in the field of metabolomics and proteomics. Before the measured mass spectral data can be used for quantitative analysis, it must be accurately corrected for isotope natural abundance and ...

Response of Summer Maize Photosynthate Accumulation and Distribution to Shading Stress Assessed by Using 13CO2 Stable Isotope Tracer in the Field. [PDF]
Front Plant Sci, 2017 Maize is one of the most important crops globally that provides food, feed, and bioenergy. However, shading stress threatens maize production. In this study, we investigated the effects of shading on photosynthate accumulation and distribution of summer ...

Stable and radiogenic isotopes as tracers for soil degradation [PDF]
, 2008 Soil erosion seriously threatens mountain slopes. Direct measurement of soil erosion in the field is difficult and needs long term recording. However, stable and radiogenic isotopes are potential tracers for soil erosion estimation and would enable a quick and easy estimation of soil erosion. Soil degradation of upland soils influences nutrient content
