Techniques developed at the Harwell Laboratory for the determination of the biopersistence of man-made mineral fibers (MMMF) in vivo are described. Results obtained with samples of glass fiber with a range of compositions, and with a sample of rockwool, are summarized. With glass fibers the rate of dissolution of fibers in vivo depends not only on their chemical composition, but also on their l...

Turner syndrome (TS) is associated with decreased bone mineral density and increased fracture rate. However, the developmental trajectory of bone density or body composition in patients with TS is still unclear. The present study tested the hypothesis that different karyotypes and/or age contributes to abnormal body composition and decreased bone mineral status parameters in patients with TS. T...

Mineral composition of dry Tamarindus indica LINN pulp and seeds was evaluated on samples collected from three different agro-ecological zones of Uganda (Lake Victoria Crescent, and Eastern and West Nile). The objective of the study was to evaluate the mineral composition of T. indica pulp and seed samples from across Uganda's different agro-ecological zones and land use types. Separately groun...

OBJECTIVE To investigate whether a postoperative weight-bearing regimen affects changes in bone mineral density and body composition after uncemented total hip arthroplasty, and to investigate the changes over a 5-year period after the surgical procedure. DESIGN Secondary analysis of a previous randomized controlled trial. METHODS A total of 39 patients were randomized to immediate full wei...

The purpose of this study was to examine associations among bone mineral density, osteopenia/osteoporosis, body mass index (BMI), and body composition in patients with heart failure (HF). A total of 119 patients (age = 61 ± 12 years, 65% male) underwent dual-energy X-ray absorptiometry scans to determine bone mineral density and body composition. In multivariable linear regressions, BMI, relati...

Body weight is positively associated with bone mineral density but the relationship between obesity and bone mineral density is unclear. Leptin and adiponectin are potential independent contributors to bone mineral density. We assessed the correlations of body composition, leptin and adiponectin with bone mineral density, and whether leptin, adiponectin and body composition determine bone miner...

An understanding of the calcification process requires exact. knowledge of the nature and variations of composition of the mineral phase of calcified tissues. Other investigators have continued the study, begun years ago, of the composition of the inorganic salts of bone, but a comprehensive study of the results of analysis of enamel and. dentin by modern methods has not been described. Crowell...
