13CO2 breath tests in non-invasive hepatological diagnosis
In liver diagnostics, a simple, non-invasive test with high sensitivity and specificity is permanently being sought in order to assess the degree of liver damage. In addition to liver biopsy, algorithms using blood parameters or elastometry are used in clinical practice. However, these methods do not provide information about the true liver reserve, so the liver breath test seem to be a promisi...
متن کاملBreath tests with stable isotopes: have they a role in liver transplantation?
Evaluation of liver function is crucial in the overall management of patients with liver disease. In particular, patients with end-stage liver disease need accurate prognostic indicators to plan liver transplantation, and in this case, to manage their presence in the waiting list. Availability of predictors of clinical outcome is further essential after liver transplant, mainly to correctly dia...
متن کاملStable carbon isotopes in exhaled breath as tracers for dietary information in birds and mammals.
The stable carbon isotope ratio of exhaled CO(2) (delta(13)C(breath)) reflects the isotopic signature of the combusted substrate and is, therefore, suitable for the non-invasive collection of dietary information from free-ranging animals. However, delta(13)C(breath) is sensitive to changes in ingested food items and the mixed combustion of exogenous and endogenous substrates. Therefore, experim...
متن کاملforaminifera and stable isotopes
Foraminiferal stable isotopes and assemblages from Franz Victoria and St. Anna troughs provide a valuable record of freshwater and Atlantic Water flows to the northern Barents and Kara seas from deglaciation to present. The dO and dC of planktonic Neogloboquadrina pachyderma (s) and benthic Elphidium excavatum were up to 1.4% lower than present at ca 13, 11.5, and 10 Cka (global sea-level corre...
متن کاملTurnover of stable carbon isotopes in the muscle, liver, and breath CO2 of alpacas (Lama pacos).
Stable carbon isotope analysis of animal liver and muscle has become a widespread tool for investigating dietary ecology. Nonetheless, stable carbon isotope turnover of these tissues has not been studied in large mammals except with isotopically labelled tracer methodologies, which do not produce carbon half-lives analogous to those derived from naturalistic diet-switch experiments. To address ...
