Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.
Composite 3D scaffolds for bone tissue engineering based on nano-hydroxyapatite and poly-ε-caprolactone were designed. The 3D composite scaffolds showed good cytocompatibility and osteogenic potential, which is specifically recommended in applications when faster mineralization is needed, such as osteoporosis treatment.

Bone decalcification is the softening of bones due to the removal of calcium ions, and can be performed as a histological technique to study bones and extract DNA. [ 1 ] [ 2 ] This process also occurs naturally during bone development and growth, and when uninhibited, can cause diseases such as osteomalacia .
The case referred by Abulcasis. The patient was pregnant in two separate occasions but never gave birth. "A long time" after, she developed a large swelling in the navel area, that turned into a suppurating wound and would not heal despite receiving treatment. This continued until Abulcasis removed several fetal bones through the wound, which ...
What happens to the bones? While flesh starts to decompose quickly, “bones will survive for decades,” points out Viddal. However, some do get broken down into smaller fragments during the ...
The body's posture changes as the pregnancy progresses. The pelvis tilts and the back arches to help keep balance. Poor posture occurs naturally from the stretching of the woman's abdominal muscles as the fetus grows. These muscles are less able to contract and keep the lower back in proper alignment. The pregnant woman has a different pattern ...
The impairment of bone metabolism causes inadequate bone mineralization. Osteomalacia in children is known as rickets, and because of this, use of the term "osteomalacia" is often restricted to the milder, adult form of the disease. Signs and symptoms can include diffuse body pains, muscle weakness, and fragility of the bones.
A new study, published April 8 in The Proceedings of National Academy of Sciences found that pregnancy can accelerate aging in young women. Researchers from the Columbia University Mailman School ...
