These growth factors modulate the differentiation of progenitor cells into osteoprogenitor cells, which are responsible for bone and cartilage formation. As a result of the demineralization process, DBM is more biologically active than undemineralized bone grafts; conversely the mechanical properties are significantly diminished. [citation needed]
Demineralization is the opposite process of mineralization; it is a process of reduction in the mineral content in tissue or an organism. Examples include bone demineralization or tooth demineralization. Demineralization can lead to serious diseases such as osteoporosis, rickets, or tooth decay. [1]
As a result of demineralization, the bones become less rigid. Physical signs include deformities like triradiate pelvis [14] and lordosis. The patient has a typical "waddling" gait. However, these physical signs may derive from a previous osteomalacial state, since bones do not regain their original shape after they become deformed.
Astronauts lose an average of more than 1% bone mass per month spent in space. [1] There is concern that during long-duration flights, excessive bone loss and the associated increase in serum calcium ion levels will interfere with execution of mission tasks and result in irreversible skeletal damage. [2]
Osteopenia, known as "low bone mass" or "low bone density", is a condition in which bone mineral density is low. [1] Because their bones are weaker, people with osteopenia may have a higher risk of fractures, and some people may go on to develop osteoporosis. [2] In 2010, 43 million older adults in the US had osteopenia. [3]
X-rays will also show bone features of renal osteodystrophy (subperiostic bone resorption, chondrocalcinosis at the knees and pubic symphysis, osteopenia and bone fractures) but may be difficult to differentiate from other conditions. Since the diagnosis of these bone abnormalities cannot be obtained correctly by current clinical, biochemical ...
The result is mineral formation not strongly controlled by the cellular processes of the animal host (i.e., remote mineralization); this may lead to unusual crystal morphologies. [ 10 ] Biologically influenced mineralization takes place when chemical conditions surrounding the site of mineral formation are influenced by abiotic processes (e.g ...
