The results reported here provide insight into the mechanism underlying the assembly of the sealing zone, the adhesion apparatus and diffusion barrier of bone resorbing osteoclasts.
To improve this numerical solution, in this work, as the main novelty, we include the diffusion of the bone remodelling into the model.
Therefore, the only indication of possible diffusion of the disease to bone was increased serum alkaline phosphatase.
Whole body diffusion MRI appears accurate for detection of bone metastases [7], even if non-specific and relying on differential vascularization and density of benign vs. cancer tissues [5].
We found that using the thermal diffusion analogy to control the modulus of bone throughout its structure provides a simple and effective method of spatially varying modulus.
Clues for diagnosis include a rapid progression of symptoms with permeative growth pattern with large soft tissue component in galeal and extradural compartment, restricted diffusion on MRI, and the presence of bone lytic lesions on CT, limited periosteal reaction and an angiographically avascular lesion except for blush or vascular encasement,.
A much more concentrated staining solution could potentially enhance diffusion through bone because of the increased concentration gradient; this suggestion should be adopted with caution while considering the serious shrinkage effect caused by more highly concentrated iodine solutions [ 6, 9].
The amorphous nature of fibrin glue makes it a candidate to control diffusion of BMP and possibly limit bone formation by limiting BMP diffusion to areas where such bone is not desired.
In vivo implantation of adenoviral osteoprogenitor constructs on PLGA biodegradeable scaffolds, using diffusion chambers, also demonstrated bone cell differentiation and production of bone tissue.
We have observed at most a very limited increase in CT values for bone over the staining process using low-concentration iodine and report that well-ossified adult bone may block diffusion of contrasting agent into the bird brain (Fig. 4).
