Inbred Strain-Specific Response to Biglycan Deficiency in the Cortical Bone of C57BL6/129 and C3H/He Mice
Description :
Inbred strain-specific differences in mice exist in bone cross-sectional geometry, mechanical properties, and indices of bone formation. Inbred strain-specific responses to external stimuli also exist, but the role of background strain in response to genetic deletion is not fully understood. Biglyca...

Repeated freeze-thawing of bone tissue affects Raman bone quality measurements
Description :
The ability to probe fresh tissue is a key feature to biomedical Raman spectroscopy. However, it is unclear how Raman spectra of calcified tissues are affected by freezing. In this study, six transverse sections of femoral cortical bone were subjected to multiple freeze/thaw cycles and probed using ...

Exercise Alters Mineral and Matrix Composition in the Absence of Adding New Bone
Author(s) :
Kohn, David H.

Morris, Michael D.
Description :
The mechanical properties of bone are dictated by its amount, distribution and ‘quality’. The composition of the mineral and matrix phases is integral to defining ‘bone quality’. Exercise can potentially increase resistance to fracture, yet the effects of exercise on skeletal fragility, and how alte...

Multichannel diffuse optical Raman tomography for bone characterization in vivo: a phantom study
Description :
Raman spectroscopy is used to gather information on the mineral and organic components of bone tissue to analyze their composition. By measuring the Raman signal of bone through spatially offset Raman spectroscopy the health of the bone can be determined. We’ve customized a system with 8 collection ...

Description :
Hydrogen-bearing species in the bone mineral environment were investigated using solid-state NMR spectroscopy of powdered bone, deproteinated bone, and B-type carbonated apatite. Using magic-angle spinning and cross-polarization techniques three types of structurally-bound water were observed in the...

Description :
Polarized Raman spectroscopy allows measurement of molecular orientation and composition and is widely used in the study of polymer systems. Here, we extend the technique to the extraction of quantitative orientation information from bone tissue, which is optically thick and highly turbid. We discus...
