osteoporosis (op) is a frequent complication of rheumatoid arthritis (ra) and longitudinal studies have documented increased rate of bone loss in ra patients. to determine the frequency of low bone mass as well as the influence of disease duration and corticosteroid use on bone mass in patients with ra, 88 patients with ra and 112 age matched controls were studied. bone densitometry was perform...

osteosarcoma (os) is the eighth common cancer of childhood and its incidence is 4 cases in one million in children younger than 14. facial os incidence is estimated between 8 and 10% of os cases. the main etiology of os is unknown, but various predisposing factors are proposed such as radiation, radiotherapy, some benign bone diseases like paget’s disease or fibrous dysplasia. there is a 5-year...

Waste materials have a great potential as sustainable and cheap sensible thermal energy storage material (STESM). There are number of previous studies on the use wastes STESM such Cofalit, coal fly ash electric arc furnace slags, by-products ilmenite mining industry potash production, municipal waste glass generated in steel industry. The aim this study is to assess demolition (DW) from urban r...

intraosseous ganglia can affect the carpal bones of the hand and must be considered in the differential diagnosis of wrist pain. a 38-year-old female presented with a 14-month history of left wrist pain and a radiolucent cystic lesion was seen computed tomography (ct) scanning. characteristic radiographic findings of a cyst in association with a fine sclerotic rim was apparent. we report an unu...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...
