[Influence of Water Content on the Biotribological Behavior of Bone Tissue]
Abstract:
In the present study,swine thighbone samples with different water contents were prepared through process of dehydration.The influence of water content on the biotribological behavior of the bone tissue was studied with nanoindentation test,reciprocating sliding test and impact wear test.It is shown that the water contents had significant influence on the mechanical properties and biotribological behavior of the swine thighbone samples.In this experiment condition,with decreasing water content,the hardness and elastic modulus of the swine thighbone samples increased,while the tribological properties significantly decreased.The viscoelasticity of bone tissue decreased with decreasing water content,which mainly resulted in different wear mechanisms of the bone tissue samples under applied loading.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...
