With a focus on nutrition as well as on infectious and lifestyle-related diseases, the Institute uses stable isotope techniques for nutrition-related research and programme evaluation.
Both muscle and liver samples were freeze-dried to a constant weight, ground to a fine power, homogenized, and stored in a desiccator for stable isotope analysis.
Recently, stable isotope analyses have been used to elucidate ontogenetic changes such as diet shifts and habitat changes during the early developmental stages of several species, for example, energy sources of larval chironomids Chironomus acerbiphilus (Goedkoop et al.
Recent and ongoing advances in the application of stable isotope analysis include quantifying the extent of biodegradation within a contaminant plume using isotopic compositions and investigating biodegradation pathways for compounds and systems with unresolved reaction mechanisms.
His research focuses on stable isotope studies of natural waters and water-rock interactions.
A comparison between labile Cd measured using stable isotope dilution and Cd extracted using 1 [MU] Ca[Cl.
In this study, we evaluate the usefulness of stable isotope analysis in investigating foraging ecology of 2 northern herbivores, moose (Alces alces) and caribou (Rangifer tarandus), based on predictions derived from the interaction between plant isotopic ecology (Table 1), diet selection of the 2 herbivores, and seasonal changes in nutritional conditions of these 2 species (Figs.
The calibration curves consisted of injected amounts of native amino acids (x-axis) vs the ratio between native amount and fixed amount of the respective stable isotope (y-axis).
We used a Europa C/N continuous-flow isotope ratio mass-spectrometer (CFIRMS, Europa, Crewe, UK) to obtain the stable isotope ratios as well as values of percentage of carbon (C) and nitrogen (N).
As it turned out, the most nearly stable isotope of the element is francium-223, which has a half-life of only 22 minutes.
