Journal ArticleDOI
Assessment of fat-free mass using bioelectrical impedance measurements of the human body
TL;DR: Data indicate that the bioelectrical impedance technique is a reliable and valid approach for the estimation of human body composition and further validation of this method is recommended in subjects with abnormal body composition.
Journal ArticleDOI
A simple, inexpensive method of determining total body water using a tracer dose of D2O and infrared absorption of biological fluids.
TL;DR: An improved infrared spectrophotometric method using tracer doses of D2O for determination of total body water (TBW) is described, showing low cost and a simple analysis that permits repeated TBW measurements over brief periods without an undue buildup of background deuterium levels in the body.
Journal ArticleDOI
Detection of labile zinc-binding ligands in biological fluids by modified gel filtration chromatography.
Journal ArticleDOI
Boron isotope ratios in commercial produce and boron-10 foliar and hydroponic enriched plants
Journal ArticleDOI
Use of inductively coupled plasma-mass spectrometry in boron-10 stable isotope experiments with plants, rats, and humans.
TL;DR: To measure boron transport in animal systems, 20 micrograms of 10B were fed to a fasted rat and 95% of the 10B was recovered from the urine and 4% from the feces.
