Gravitational Loading and Changes in Bone Metabolism.

Age related changes in indices of bone metabolism and oxidative stress in Postmenopausal women in Southern Nigeria

Background and Objectives: Oxidative stress (OS) associated with estrogen deficiency in menopause has been implicated in various complications of menopause. Some indices of OS, bone metabolism, and uric acid (UA) in postmenopausal women were assessed as possible predictors of gouty osteoarthritis. Materials and Methods: This case-control study enrolled 40 postmenopausal women and 60 premenopau...

Regulation of Bone Metabolism

Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...

Changes in Bone Metabolisim Around Osseointegrated Implants Under Loading

Clinical impact of bone and calcium metabolism changes in sarcoidosis.

Even before the introduction of X-rays, Besnier had noted the association of swelling of the fingers with lupus pernio. In 1904 Karl Kreibich, later Professor of Dermatology in Prague but at that time working in Vienna, described four patients with cystic changes in the bones of the hand in connection with lupus pernio and gave an excellent radiographic reproduction of the hands in one and sarc...

Changes in Bone Metabolism in Young Castrated Male Rats

PURPOSE To determine the window of time during which osteoporosis affects the management of spinal surgery and the mechanism of bone metabolism changes in males with osteoporosis by examining changes in bone metabolism in young castrated male rats. MATERIALS AND METHODS A total of 30 Sprague-Dawley rats were randomly allocated into two study groups. Group 1 (control) received a sham surgery a...
