These results, associated with a reduction in thigh skinfold measurements, we speculated may indicate an increase in muscle mass, although direct measurements of lean mass gains were not explored in this study.
For all clinic sites, the CVs were <1.7% for measurements of fat mass and <1.5% for measurements of lean mass.
To assess the accuracy of BIA-derived massle mass, this is compared to whole body DXA (Hologic Discovery A) measurements of lean tissue mass in a subgroup of patients (n = 20) (this is performed within 3 days of BIA).
Measurements of lean, fat, and fluid mass in live mice were acquired by nuclear magnetic resonance (NMR) using the Minispec LF90 (Bruker Optics, Billerica, MA, USA) (n = 15 SD, n = 13 SRT2104; 76 weeks age; 49 weeks diet).
In brief, six selected slices from the L2-L5 vertebral spaces (i.e. two each at L2 L3, L3 L4, and L4 L5) were obtained for measurement of abdominal lean muscle mass (in cm).
The Pearl Chain Manufacturing Organization (PCMO) is a concept for control and measurement the stability of lean activities.
This specific DXA unit provides a reliable and accurate measurement of distribution of lean and fat mass [ 59].
To optimize the efficiency and safety of mixtures of nonozone-depleting refrigerant replacements, precise measurements of the lean flammability limits of pure refrigerants and the critical flammability ratio of their mixtures are crucial.
The coefficients of variation of measurements of BMC, lean and fat mass were 0.9, 1.0 and 2.0%, respectively.
Indeed, BIA seems to overestimate ALM/ht compared to DXA and, consequently, it is important to use an adapted formula to obtain measurement of the appendicular lean mass by BIA close to that measured by DXA.
