objective: biodegradable polycaprolactone/starch composites can be used for bone tissue engineering applications. the effect of the ratio of components on composite properties is of tremendous importance. methods: polycaprolactone/starch composite of 80/20 and 70/30 ratios were fabricated by dissolving them in chloroform followed by evaporation of the solvent. results: the composites were chara...
Objective: Alveolar ridge preservation in patients with inadequate bone volume is one treatment option for successful implant placement and can be done by using bone graft materials. On the other hand, Ceno Bone has been recently produced by Hamanand Saz Baft Kish Co. as a bone bioimplant of allograft origin. This study aimed to assess the clinical, histologic and histomorphometric results of...
The positive effect of Si and Zn ions on bone formation and metabolism has already been confirmed. The aim of this study was preparation and characterization of Willemite (Zn2SiO4) for the repair of bone defects. Willemite was prepared through solid state reaction. Phase analysis and chemical compositions were investigated. The zeta potential of the nanoparticles was determined in physiological...
Bone remodeling, comprising resorption of existing bone and de novo bone formation, is required for the maintenance of a constant bone mass. Prostaglandin (PG)E2 promotes both bone resorption and bone formation. By infusing PGE2 to mice lacking each of four PGE receptor (EP) subtypes, we have identified EP4 as the receptor that mediates bone formation in response to this agent. Consistently, bo...
Background: Osteoporosis is one of the uncomfortable postmenopausal symptoms. The risk of imbalanced nutrition especially traces elements and vitamins are high during post menopause and may lead to osteoporosis due to reduction of content of mineral bone. The aim of this study was to investigate the potential consequence of Selenium (Se) treatment in ovariectomized rat model with osteoporosis i...
