Multigenerational interstitial growth of biological tissues

Interstitial growth and remodeling of biological tissues: tissue composition as state variables.

Growth and remodeling of biological tissues involves mass exchanges between soluble building blocks in the tissue's interstitial fluid and the various constituents of cells and the extracellular matrix. As the content of these various constituents evolves with growth, associated material properties, such as the elastic modulus of the extracellular matrix, may similarly evolve. Therefore, growth...

Interstitial Cells Tissues

The plasma compartment, on which almost all routine analyses in clinical chemistry are performed, occupies only a small part of the body, most of which consists of cells. For most components the intracellular and extracellular comrn partments have a different composition in health, and change differently in disease. The readily available cells are erythrocytes, and although these can be used fo...

Mechanical Properties of Biological Tissues

The material response discussed in the previous chapters was limited to the response of elastic materials, in particular to linearly elastic materials. Most metals, for example, exhibit linearly elastic behavior when they are subjected to relatively low stresses at room temperature. They undergo plastic deformations at high stress levels. For an elastic material, the relationship between stress...

Microwave Imaging of Biological Tissues

Photon Diffusion in Biological Tissues

The use of laser-based optical techniques for medical imaging is an attractive alternative to other methods that utilize ionizing radiation. Beside being non-carcinogenic, it is non-invasive, the equipment is transportable, and the methodology can be used to examine properties of soft tissue. However, unlike x-ray photons, optical photons generated in the near-infrared suffer significant amount...
