A non-invasive, on-line deuterium dilution technique for the measurement of total body water in haemodialysis patients.
BACKGROUND Despite its importance, total body water (TBW) is usually estimated rather than measured due to the complexity of isotope dilution methods. The aim of this study was to demonstrate the applicability in haemodialysis (HD) patients of a recently developed on-line breath test, previously validated in healthy subjects, that uses the gold standard deuterium dilution method to measure TBW....
متن کاملEvaluation of human allogeneic collagen gel for correction of nasolabial folds using non-invasive measurement techniques
Background: With aging, the facial folds, grooves, and sagging tissue become more prominent. It is haracterized by loss of the collagen mass in the dermis and an increased array of elastin whirls in the deeper dermis. The aim of this study was to determine whether correction of nasolabial folds could be achieved using an allogeneic collagen product. Methods: Nine healthy volunteers participated...

Measurement of total body water using H dilution: impact of different calculations for determining body fat
This study estimated total body water (TBW) in four groups (twelve per group; sedentary and highly trained men and women) at the time of H dosing (T0) and after a 3·5 h equilibration period (Teq). Standard TBW calculations were employed at T0 (no correction for disproportionate urinary tracer loss) and Teq (correction for urinary tracer loss only), plus those calculations that corrected for a d...
