Objectives: To establish the correlations between the body composition, somatotypes and average bone mineral density (BMD) and bone mineral content (BMC) in young (17–18 y.o.) male living in Donbass region (Ukraine).Materials and methods: Anthropometric and skinfold measurements were carried out. Estimations of the calcaneal BMD (g/cm2) and BMC, (r), estimated on ALOKA-5.0 DXA machine among 156 male were done. Total body fat perc...

The selective cathepsin K inhibitor odanacatib (ODN) is currently in development for the treatment of postmenopausal osteoporosis. Our goal was to evaluate the effects of ODN vs alendronate (ALN) on bone mass and strength of lumbar vertebrae (LV) in orchiectomized (ORX) rabbits, a model of male osteoporosis. Adult male rabbits (11 months old) were subjected to sham- (n=20) or ORX-surgery (n=24/group) for 7.5 months before dosing initiated. ORX animals were ra...

Introduction: Genetic disorders are usually characterised by subjective morphological traits. Mouse models should represent the human situation but it is difficult to translate morphology traits from one species to another. Thus, there is a demand to objectively assess morphological traits. Geometric morphometrics is a mathematical tool to evaluate morphology based on normalised three-dimensional coordinates. Here we use geometric morphometrics to compare the morphology of <em...

It is unclear as to whether western dwelling South Asian (SA) postmenopausal women have a different fracture risk to that of the native Caucasian (C) population. Moreover, the WHO Fracture Risk Assessment Tool (FRAX) has not been used previously to compare predicted risk of fractures in western dwelling South Asian women with same-age Caucasian women. This analysis used data from n=35 SA [mean (S.D.) age=59 (6) years] and n=136 C [mean (...

Extreme high bone mass (HBM) may be monogenic (e.g. due to mutations in SOST or LRP5) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine the genetic cause underlying HBM in an extreme HBM population.258 unexplained HBM cases (defined as L1 Z-score ≥+3.2 plus total hip Z-score ≥+1.2, or total hip Z-score ≥+3.2 and L1 <...

Objective: Autism Spectrum Disorder (ASD) is associated with lower bone mass in children. Physical activity and nutrition influence bone pathophysiology, and differences in these lifestyle factors are observed between children with vs. without ASD; however, whether these factors contribute to bone differences is unknown. We examined if: 1) differences existed in bone mineral density (BMD), content (BMC), or bone geometry in boys with vs without ASD and 2) whether physical acti...

Study aim: Vertebral strength is determined by bone size, shape, bone mineral density, microarchitecture, and bone material properties. Despite its importance to vertebral mechanics, no studies have reported on the variation of bone microdamage present in the human vertebra. Thus, the aim of this study was to assess regional changes in trabecular bone microdamage in association with bone microarchitecture and resorption in whole human lumbar vertebrae.Me...

Study aim: The general assumption that changes in bone microstructure and material properties at the iliac crest are representative of skeletal sites that are susceptible to osteoporotic fracture has not yet been addressed. Therefore, our study aim was to perform a comparative analysis of bone microarchitecture, accumulated microdamage and osteocyte morphology between the iliac crest, proximal femur and vertebral body.Methods: Trabecular bone cores were ...
