Mechanical validation of a tomographic (pQCT) index for noninvasive estimation of rat femur bending strength.
Cross-sectional moment of inertia (CSMI) and volumetric cortical bone mineral density (vCtBMD) were assessed by peripheral quantitative computed tomography (pQCT) at femur midshafts from 103 Wistar… Expand

This study analyses the evaluation of tomographic indicators of tibia structure, assuming that the usual loading pattern shifts from uniaxial compression close to the heel to a combined compression,… Expand
A DXA study of muscle-bone relationships in the whole body and limbs of 2512 normal men and pre- and post-menopausal women.
A whole-body DXA study of 1450 healthy Caucasian individuals [Bone 22 (1998) 683] found that mineral mass, either crude (BMC) or statistically adjusted to fat mass (FM-adjusted BMC), correlated… Expand

This observational study analyzes Ca-P metabolism and its impact on bone mass accrual and density and the muscle-bone mass/mass relationships in male and female children and adolescents who were… Expand
Absorptiometric assessment of muscle-bone relationships in humans: reference, validation, and application studies
This report summarizes some preliminary absorptiometric (DXA, QCT/pQCT) studies from our laboratory, supporting the following assumptions. 1. InHomo sapiens at all ages, natural proportionality… Expand
Z-scoring of pQCT-assessed, reference distribution/quality curves in the human tibia to evaluate the efficiency of bone mechanostat
The efficiency of bone mechanostat to control bone stiffness/strength could be assessed as the adequacy of the spatial distribution of bone tissue as a function of its stiffness at any given skeletal… Expand
