The use of stable isotopes combined with mass spectrometry (MS) provides insight into
metabolic processes within the body. Herein, an overview on the relevance of stable isotope …

Population viability is driven by individual survival, which in turn depends on individuals
balancing energy budgets. As carnivores may function close to maximum sustained power …

Background Assessment of hydration status in patients with chronic kidney failure treated by
dialysis is crucial for clinical management decisions. Dilution techniques are considered the …

Background: High protein intake in early life is associated with an increased risk of
childhood obesity. Dietary protein intake may be a key mechanistic modulator through …

Objectives: To assess validity evidence of TracmorD to determine energy used for physical
activity in 3‐4‐year‐old children. Design and Methods: Participants were randomly selected …

Purpose Despite the significant interest in molecular hydrogen as an antioxidant in the last
eight years, its quantitative metabolic parameters in vivo are still lacking, as is an …

Less invasive protocols are necessary to study energy expenditure (EE) of cats living in
homes for expressing their normal living conditions. The present study compared sampling …

Saliva and urine are the two main body fluids sampled when breast milk intake is measured
with the 2H oxide dose-to-mother technique. However, these two body fluids may generate …

Rationale The doubly labelled water (DLW) method is a stable isotopic technique for
measuring total energy expenditure (TEE). Saliva is the easiest sampling fluid for assessing …

BACKGROUND & AIMS: Information is lacking on the comparability of the outcomes of the
doubly labeled water method using urine and saliva samples in children with severe …
