BACKGROUND AND PURPOSE Experimental models of osteoporosis in rabbits are useful to investigate anabolic agents because rabbits have an active Haversian remodeling and achieve skeletal maturity quickly. In this study, an experimental model of osteoporosis in rabbits induced by a combination of ovariectomy and glucocorticoid was characterized to provide a useful model for prevention and therapy ...

BACKGROUND Spinal anesthesia (SA) is the most common regional anesthesia (RA) conducted for many surgical procedures. OBJECTIVES The current study aimed to predict the difficulty score of SA, by which to reduce the complications and ultimately improve the anesthesia quality. MATERIALS AND METHODS Transurethral Lithotripsy (TUL) surgery candidates were enrolled in this observational study fr...

BACKGROUND Intervertebral disc (IVD) degeneration and pathological changes in the spinal cord are major causes of back pain. In addition to its well-established anti-resorptive effect on bone, calcitonin (CT) potentially exerts protective effects on IVD degeneration in ovariectomized rats. However, possible therapeutic effects of CT on lumbar fusion-induced adjacent-segment disc degeneration (A...

Background and Aim: Temporomandibular joint osteoarthritis (TMJOA) appears to be more common in osteoporotic patients. Fractal analysis is a mathematical method that can be used to assess trabecular bone. The aim of this study was to assess the correlation of bone mineral density (BMD) and fractal dimension (FD) of the condyles in women with TMJOA using cone-beam computed tomography (CBCT).   ...

The double S shape of the vertebral column is one of the most important evolutionary adaptations to human bipedal locomotion, providing an optimal compromise between stability and mobility. It is commonly believed that a six element long lumbar spine facilitated the critical adoption of lumbar lordosis in early hominins, which contrasts with five lumbars in modern humans and four in chimpanzees...

BACKGROUND Many studies have identified smoking as a risk factor for osteoporosis, but it is unclear whether passive smoking has an effect on bone mineral density and bone turnover and if such an effect could cause osteoporosis.The purpose of the study was to investigate the effect of passive smoking on bone mineral density (BMD) and bone turnover and the relationship between BMD and bone turno...
