objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...

background: bone-specific alkaline phosphatase (bap) is synthesized by the osteoblasts and is presumed to be involved in the calcification of bone matrix, though its precise role in the formation process is unknown. the aim of the present study was to measure the bap activity in paget's and normal specimens by two different techniques. methods: total alp (tap) as well as bap activity-measu...

objective: florid cemento-osseous dysplasia (fcod) is a rare bone lesion that predominantly involves the women’s jaws in middle age. this condition is usually asymptomatic and has a benign course.   case: this paper presents a rare case of fcod in a white middle aged woman, which had affected mandible bilaterally and was diagnosed after tooth extraction and treated conservatively.   we believed...

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 bo...

Effective regeneration of adsorbents is considered as one the essential qualities for commercial use. However, most studies have only reported adsorption properties and overlooked reuse adsorbents. In this study, we determined regenerability reusability fly-ash derived zeolite (FADZ) NaP1. These become popular to remove pollutants from water, including toxic metals, since they are less expensiv...

In this research, chitosan–magnetite composites (CS-MNPs) were successfully synthesized using a rapid and easy technique. The materials characterized by FTIR, XRD, EDX, TEM, VSM, BET methods. removal of the antibiotics ciprofloxacin (CFX) levofloxacin (LFX) from aqueous solutions CS-MNPs adsorbent was investigated. influencing factors in single adsorption system studied, including pH (1–11), in...

objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

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...
