Relations between mineralisation and mechanical properties have been investigated in human femoral compacta. Evidence of age-related changes in physical properties of bone, independent of mineral density, is provided by significant (P less than 0.05) partial correlation between ultimate tensile stress and age. However, 75 per cent of variance in ultimate(More)
Tensile and compressive strength of human femoral compacta have been shown to be related (P is greater than 0.005) to the average bone apatite crystallite length (D002) as determined by X-ray diffraction line breadth measurement. However, statistical variance of crystallite length was not sufficient to explain observed differences in mechanical properties,(More)
When assessing the mineral content of the skeleton investigators customarily make either radiographic or photon absorption measurements at one particular site on the assumption that the site selected is representative of the remainder of the skeleton. Unfortunately few of the established techniques for bone mineral quantification actually provide(More)
Green fluorescent protein (GFP) was first isolated in the early 1970s for experimental use from coelenterates or the Pacific jellyfish. Aequorea victoria (Morin and Hastings, 1971). GFP has since become a favored biomarker in the photophysical analysis of molecular and cell biology because of its strong intrinsic visible fluorescence and the feasibility of(More)
Positive correlation between the mineral content of the mid site of right third metacarpal and neck of femur has been established using the psi-ray absorption technique described by Shimmins et al. (1972b) to make measurements on excised human bones. An X-ray method (Anderson, Shimmins and Smith, 1966; Shimmins et al. 1972a) was used to measure the mineral(More)
Detection and analysis of bacteria from environmental samples (e.g. water, air, and food) are usually accomplished by standard culture techniques or by analyses that target specific DNA sequences, antigens or chemicals. For large cell numbers in aqueous suspensions, an alternative technique that has proven useful is total luminescence spectroscopy (TLS).(More)
