Introduction: The low regeneration of bone in defective bones causes therapeutic problems. Various strategies to assess the healing of bone defects have been used which they include histological and histo-chemical analysis in an invasive study. The purpose of this study was to determine the ultrasonic parameters of bone as a promising noninvasive technology for assessing bone repair process. Ma...

Objective(s): BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN) and bone scan index (BSI) values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, t...

background mandibular continuity defects occur after tumor resection, maxillofacial injury, or osteomyelitis. despite the current availability of a plethora of treatment modalities, bone substitutes, and various clinical adjuncts, an exact reconstructive recapitulation of large bony defects continues to be beyond reach. in this clinical pilot study, we report a novel method for reconstruction o...

the present study assessed the real life therapeutic effects of weekly doses of alendronate in treating a group of osteoporotic patients in iran. the present historical cohort was conducted on patients who had undergone two or more bone mineral densitometry within an interval of 1.5-2 years in shariati hospital bone mineral density department between 2002 and 2010.patients were asked by phone a...

osteoporosis is a major public health problem in iran. bone densitometry is used to diagnose osteopenia and osteoporosis and if necessary, prevent bone fractures, especially that of femoral neck. bone density is related to several factors including race, age, sex, environmental factors and nutrition. no comprehensive study has been performed in iran, yet. among the 10 to 75 year-old population ...

Background: Hypothyroidism is associated with dysfunction of the bone turnover with reduced osteoblastic bone formation and osteoclastic bone resorption. Mesenchymal stem cells (MSCs) secrete various factors and cytokines that may stimulate bone regeneration.  The aim of this study was to determine the effects of MSCs-conditioned medium (CM) in hypothyroidism male rats after inducing bone ...

Objective(s): Alcohol consumption induces oxidative stress on bone, which in turn increases the risk of osteoporosis. This study determined the effects of vitamin E on bone strength and bone mineral content in alcohol-induced osteoporotic rats. Materials and Methods: Three months old Sprague Dawley male rats were randomly divided into 5 groups: (I) control group; (II) alcohol (3 g/kg) + normal ...
