Direct calculation of the surface-to-volume ratio for human cancellous bone.
There are many diseases which cause detrimental changes in the trabecular structure of cancellous bone, leading to mechanical failure of the tissue. One approach to understanding the mechanisms of these diseases is to create idealized models that recreate the morphology of the tissue. This paper presents a partial development of such a model. Further histological methods must be developed befor...
متن کاملeffect of hyperglycemic condition on observed surface area to volume ratio of human cancerous cells
the human blood basal glucose level is a completely controlled range. information on the relationship between culture glucose concentration and changes in the cell's surface area, volume and surface area to volume (s/v) ratio are lacking. cancerous epithelial-like cell lines sw480, sw742 and t-47d were cultured in mediums nourished with 4.7 mm per liter of glucose as the control group and three...
متن کاملSurface-to-volume ratio with oscillating gradients.
Restrictions to diffusion result in the dispersion of the bulk diffusion coefficient. We derive the exact universal high-frequency behavior of the diffusion coefficient in terms of the surface-to-volume ratio of the restrictions. This frequency dependence can be applied to quantify structure of complex samples with NMR using oscillating field gradients and static-gradient CPMG. We also demonstr...

Direct perfusion measurements of cancellous bone anisotropic permeability.
More extensive characterization of trabecular connectivity and intertrabecular space will be instrumental in understanding disease states and designing engineered bone. This project presents an experimental protocol to define the directional dependence of transport properties as measured from healthy cancellous bone when considered as a biologic, porous medium. In the initial design phases, mat...
