Calcitonin and postmenopausal bone loss
Experimental Gerontology, 1990In order to establish the role of calcitonin (CT) in postmenopausal bone loss, we studied CT metabolism in 25 pre- and postmenopausal women. Postmenopausal women presented a highly significant reduction of CT basal levels compared to premenopausal females (p less than 0.01). Also, production rates of CT in osteoporotics were significantly lower than in

The skeleton has two major functions: it provides structural support and acts as a mineral reservoir. It responds dynamically to hormones and mechanical stress, homeostatic factors that control serum calcium and skeletal architecture, geometry and bone mineral content.

Clinical Orthopaedics and Related Research, 1982
A survey was done of aging changes in compact and trabecular bone. During the past decade, noninvasive methods have demonstrated similar results for compact bone in large samples. Aging decreases of 3%/decade begin at about age 40 in both sexes and continue, but in women, an additional loss occurs after menopause, bringing their total rate of decrease ...

The pathophysiology of bone loss
Clinics in Geriatric Medicine, 2003Aging is associated with a decline in cancellous and cortical bone mass and with a deterioration of microarchitecture in both skeletal compartments. These changes are more marked in women than men and are exaggerated in patients with fracture. With the insight gained from histomorphometry, we are beginning to understand the cellular mechanisms that ...

When Garn et al. (1967) concluded that aging bone loss is universal, they were referring to the human species. Subsequent research has shown that this conclusion extends to all other species of vertebrates so far examined, from laboratory rodents to non-human species living in the wild.

Assessment of bone density and bone loss
Osteoporosis International, 1996Dual-energy X-ray absorptiometry has become the standard for the evaluation of osteoporosis. It is useful both for identifying those people who are going to be at risk of fracture in the future, and for monitoring therapy when the measurements are made at the lumbar spine.

Bone Cell Precursors and the Pathophysiology of Bone Loss
Annals of the New York Academy of Sciences, 2006Abstract: In health, changes in bone formation and degradation rates are coupled and adequate cellular resources are available in the bone so that a change in bone formation rate occurs with an opposing change in resorption. On the other hand, the regulation of bone volume, particularly in pathological conditions, is dependent not only on the ...

The Role of Autoantibodies in Bone Metabolism and Bone Loss
Calcified Tissue International, 2017Many autoimmune diseases are associated with deranged bone metabolism. The resulting localized or systemic bone loss can compromise the quality of life of patients by causing local bone deformities or fragility fractures. There is emerging evidence that antibodies have a direct impact on key players of bone homeostasis, in particular osteoclasts ...

Vertebral bone loss in menopause
Experimental Gerontology, 1990A direct correlation between loss of ovarian function and reduction of bone mass is well established. The incidence of fractures sharply increases with age starting from the menopause. Therefore, it is very important to know the rate of bone loss occurring after menopause, at both trabecular and cortical levels.
