Background: No scientific evidence exists regarding the amount of bone cement used and discarded in primarycemented Total knee arthroplasty (TKA). The aim of this study was to identify the exact amount of bone cement utilizedfor component fixation in primary TKA.Methods: In a prospective study carried out at five centers, 133 primary cemented TKAs were performed. One packof 40g Palacos bone cem...

Osteoporosis is a systemic skeletal disease and there is a close relationship between the sympathetic nervous system (SNS) and bone metabolism. Leptin has been shown to regulate bone formation and bone resorption via the SNS. However, the effect of SNS on leptin signaling has not been clearly understood. In the present study, we studied the effect of propranolol on ovariectomy-induced osteoporo...

Introduction: To achieve the best esthetic and functional results of implantation and patient satisfaction, different protocols of implant therapy have been recommended. Immediate implantation can provide the outcome faster than other protocols making it the treatment of choice. The rate of peri-implant bone resorption should be measured clinically and radiographically as bone support is a key ...

background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...

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 ...

in order to study the normal hematopoiesis, cellular components and myeloid/erythroid (m/e) ratio in the bone marrow of the pheasant (phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. the bone marrow smears were stained using the giemsa stain. the results indicated that the development and formation of blood cell...

Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and relatively routine imaging technique in dentistry; it could provide an opportunistic chance for screening osteoporosis. In this regard, numerous...
