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.
Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
Osteomalacia is a disease characterized by the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium. The impairment of bone metabolism causes inadequate bone mineralization.
The ectopic pregnancy happened shortly after the birth of the patient's first child. Afterwards she was pregnant seven times more, giving birth to her last child just two months before the diagnosis. [27] Unknown (68) Northern Cape, South Africa 1986 2011; not extracted (25 years) Fourth pregnancy, when the patient was aged 44.
During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell concentration.
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 ...
[1] [2] The symptoms usually appear during or after a first pregnancy with the most common complaint being severe back pain [3] The exact causes of the disease are not yet known, and most women with PLO have no known predisposing cause of osteoporosis or bone fragility.
Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle.
