Measurement of energy expenditure: the doubly-labelled-water method in clinical practice.
The doubly-labelled-water method is now being regularly exploited to measure energy expenditure in human studies. Initial differences of opinion relating to the fine details of the methodology have to a large extent been resolved, and we have arrived at a stage where it is likely that researchers unschooled in mass spectrometry and the use of stable isotopes may wish to apply the method to prob...
متن کاملEnergy requirements assessed using the doubly-labelled water method.
Energy requirements of animals and man were originally determined in intake–balance studies, measuring the energy intake to maintain energy balance. Nowadays energy requirements are preferably determined by measuring energy expenditure. During growth, energy expenditure is combined with a figure for energy deposition. The reasons for the switch from intake to expenditure measurements are twofol...
متن کاملLabelled Propositional Modal Logics: Theory and Practice
We show how labelled deductive systems can be combined with a logical framework to provide a natural deduction implementation of a large and well-known class of propositional modal logics (including K, D, T, B, S4, S4:2, KD45, S5). Our approach is modular and based on a separation between a base logic and a labelling algebra, which interact through a xed interface. While the base logic stays xe...
متن کاملDoubly labelled water: Multi-point and two-point methods in pre-school children.
OBJECTIVE We compared the multi-sample and two-sample methods for measuring total energy expenditure (TEE) using doubly labelled water (DLW) in pre-school children to establish whether taking multiple samples provides any advantage in free-living conditions. METHODS Sixty-five children (32 boys; aged 2-6 years) were recruited from Aberdeen, UK. TEE was measured over 7 and 14 days using the mu...
متن کاملMilk intake and carbon dioxide production of piglets determined with the doubly labelled water technique.
The present study was undertaken to study different methodological aspects of quantifying CO2 production and milk intake of suckling piglets using the doubly labelled water (DLW) technique. In total, 37 piglets were enriched intraperitoneally with DLW to study equilibration time of 18O (n = 3), to validate the estimation of milk intake and CO2 production (n = 10) of piglets fed milk replacer an...
