چکیده سابقه و هدف بازسازی ضایعات استخوانی از اهداف ایده آل درمان های پریو دنتال و ایمپلنتهای دندانی می باشد.بیومتریالهای مختلفی به منظور دستیابی به این هدف استفاده شده و مطالعات زیادی سعی در مقایسه ومعرفی بهترین آن ها داشته است. تحقیق حاضر با هدف بررسی هیستولوژیک و هیستومورفومتریک کاربرد nanocrystalline hydroxyapatite silica gel ، fdba و pdfdb در بازسازی نقائص استخوانی کالواریای خرگوش انجام ...
Results HRs for overall mortality changed markedly over time, most notably for persons in same-sex marriage. In 2000–2011, opposite-sex married persons (reference, HR1⁄4 1) had consistently lower mortality than persons in other marital status categories in women (HRs 1.37–1.89) and men (HRs 1.37–1.66). Mortality was particularly high for same-sex married women (HR1⁄4 1.89), notably from suicide...
Gamma transparent materials are necessary to avoid detection Development of a small area (1-2 cm2) in situ beta imaging device includes optimization of the front end scintillation detector which is fiber optically coupled to a remote photon detector. Thin plastic scintillation detectors, which are sensitive to charged particles, are the ideal detectors due to the low sensitivity to ambient gamm...
Static bone scan was performed in 46 patients for evaluation of ocular Hydroxyapatite Vascularization. Study Findings indicated that bone scan, with TC-99m MDP is an appropriate method for evaluation of Hydroxyapatite Vascularization and for estimating the time For peg insertion into the Hydroxyapatite implant. Our study showed proper Hydroxyapatite Vascularization when the ratio of activ...
The aim of the present study was to examine the adsorption of bovine serum albumin (BSA) to hydroxyapatite surfaces by means of zeta potential. The electrophoretic mobility of both hydroxyapatite and BSA were negative, with BSA itself less negative than hydroxyapatite. The zeta potential of the surface of BSA-adsorbed hydroxyapatite was significantly more negative than that of hydroxyapatite al...
