The concept of bone quality describes the sets of the characteristics of the osseous tissue that influence bone strength. The aim was to explore the influence of anthropometric parameters and age on the parameters of the bone architecture and bone mineral properties in the lumbar vertebral bone of men and women. Vertebral bone samples underwent bone histomorphometry, bone densitometry and atomi...

Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve calcium phosphate (Ca-P), ferric phosphate (Fe-P) and aluminium phosphate (Al-P) efficiently. STMPSB 8 (Klebsiella pneumoniae) could be design...

Details are given of the techniques used in the analysis of asbestiform fibers in the water systems of Duluth, Minnesota and other cities. Photographic electron diffraction and electron microprobe analyses indicated that the concentration of verified amphibole mineral fibers ranged from 20 x 10(6) to 75 x 10(6) fibers/l. Approximately 50-60% of the fibers were in the cummingtonite-grunerite ser...

The bark of some medicinal trees (Alstonia boonei, Pycnanthus angolensis, Anacardium occidentale, Mangifera indica, Khaya iroresis, Nauclea diderichii, Morinda lucida and Bridelia micrantha) found in Nigeria were analysed for mineral composition and phytochemical screening. The mineral composition were determined and found to contain some elements such as sodium, potassium, calcium, magnesium, ...

Lead in bone can be measured in vivo using gamma-rays from a 109Cd source to excite lead K X-rays. Normalization of lead X-ray amplitudes to that of the elastically backscattered 88 keV gamma-rays produces a determination of the concentration of lead in bone mineral that is accurate and insensitive to variations in measurement or bone geometry. For in vivo tibia measurements, a typical precisio...
