the objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual x-ray and laser (dxl) in a cross-sectional study carried out in an osteoporosis clinic. measurements of bone mineral density (bmd) at proximal femur and spine were obtained by dual-energy photon x-ray absorptiometry (dexa). osteoporosis was defined by a dexa t-score <-2.5 at the femora...

Results As reported previously, with Micro-CT we can get better images because of the higher resolution. Micro-CT is a useful tool in defining bony morphology and the structure. Bone maturity such as distraction osteogenesis which results in increased bone mineral density (BMD) is one example of the effects of exposure to ultrasound. High BMD values are reported to increase the rate of bone agi...

Bone mineral density (BMD) and content (BMC) were measured in 208 institutionalised patients with refractory epilepsy. BMD was in the osteoporotic range in 43% of males and 21% of females. BMC was reduced only in male patients. Apart from age and gender, no other factor or specific AED was particularly associated with reduced BMD or BMC. This study indicates the magnitude of the problem of bone...

OBJECTIVE The links between osteoporosis and arteriosclerosis have been established by numerous epidemiological studies. Could arteriosclerosis induce bone mineral loss via ischemia or other pathological process? We carried out a comparative study of bone mineral density in both legs of patients with unilateral arterial disease of the lower limbs. METHODS We studied 25 patients, 22 men and 3 ...

Dual energy X-ray absorptiometry (DXA) measurements from different manufacturers provide different bone mineral density (BMD) values and derived T-scores and Z-scores. These differences result partly from technical differences in the algorithms for the determination of bone mineral content and bone area and partly from the use of different manufacturer-derived reference databases. The present s...

Daily subcutaneous administration of bovine parathyroid hormone (PTH)(1-34) stimulates bone formation and increases bone mass in rat tibiae, femora and lumbar spine. However, the effects of PTH on the whole body bone mineral content and density determined by dual energy x-ray absortiometry (DEXA) have not been previously reported in rats. Eighteen-month-old intact female rats were subcutaneousl...

BACKGROUND Bariatric surgery is the most effective treatment for achieving a significant weight loss. Morbidities present a significant reduction after bariatric surgery, but it may also result in several health complications, related to nutritional deficiencies, including bone metabolism. Several studies have reported a decrease in bone mineral density (BMD), but most of them referring to mala...

fracture. several chronic medical conditions, medications, and life style factors affect bone mineral accrual. this study aims to evaluate the bone mineral densities and hip axis lengths in the local population. materials and methods: 336 normal bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (bmds) by means of dual x-ray absorptiometry (dxa). results:...

BACKGROUND Maintaining and building healthy bones during the lifetime requires a complicated interaction between a number of physiological and lifestyle factors. Our goal of this study was to analyze the association between hand grip strength and the maximum peak expiratory flow with bone mineral density and content in adolescent students. METHODS The research team studied 1427 adolescent stu...

Introduction:There is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. This study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal Kurdish women. M...
