AbstractChanges in bone architecture and metabolism with aging increase the likelihood of osteoporosis and fracture. Age‐onset osteoporosis is multifactorial, with contributory extrinsic and intrinsic factors including certain medical problems, specific prescription drugs, estrogen loss, secondary hyperparathyroidism, microenvironmental and cellular ...

Skeletal bone age assessment is a common clinical practice to investigate endocrinology, and genetic and growth disorders of children. However, clinical interpretation and bone age analyses are time-consuming, labor intensive, and often subject to inter ...

Baillière's Clinical Rheumatology, 1993
Bone can be divided into two kinds of tissue, cortical and trabecular bone. The skeleton comprises approximately 80% cortical bone, mainly in peripheral bones, and 20% trabecular bone, mainly in the axial skeleton. Bone density increases with skeletal growth to a peak in late adolescence or early adulthood.

Pediatrics In Review, 1993
Skeletal maturation is expressed as bone age or skeletal age. Bone age is based on the orderly appearance of the ossification centers and, therefore, on the successive stages of the development (or maturity) of the skeleton as seen on radiographs. This is not a measure of size, but rather of shape and position.

Current Pharmaceutical Biotechnology, 2017
The decline of tissue function in ageing is a consequence of many changes in the gene expression and other extrinsic factors. The molecular mechanisms underlying these changes are heavily investigated with focus on regulation of time-lapse gene expression.

Osteoporosis International, 2007
We investigated whether the age of the bones endogenously exerts control over the bone resorption ability of the osteoclasts, and found that osteoclasts preferentially develop and resorb bone on aged bone. These findings indicate that the bone matrix itself plays a role in targeted remodeling of aged bones.Osteoclasts resorb aging bone in order to ...

Gerodontology, 1998
AbstractChanges in bone structure as a function of age have been studied by simple inspection, x‐ray imaging, stereo‐photography, deep field optical microscopy, circularly polarised light microscopy, and scanning electron microscopy (SEM), including both topographic and compositional backscattered electron (BSE) imaging modes.

Besides mechanical and protective function, bone serves as a keeper for marrow cells and an organ for regulation of calcium ion homeostasis. During aging, significant amounts of the bone are lost due to the loss of this delicate balance toward increased bone resorption coupled with decreased formation, which leads to net bone loss of the aging people ...

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 ...

Experimental Gerontology, 1991
Bone changes occur during normal aging in both men and women. Changes are both quantitative and qualitative in nature, and include: 1) alterations in the dynamics of bone cell populations, resulting in uncoupling of the normal process of bone resorption and formation; 2) changes in bone architecture (e.g., rearrangement of trabecular struts) and cross ...
