MRI may be a noninvasive and alternative tool for skeletal age assessment in children, although few studies have reported on this topic. In this article, skeletal age was assessed over a wide range of ages using an open, compact MRI optimized for the imaging of a child's hand and wrist, and its validity was evaluated. MR images and their three-dimensional segmentation visualized detailed skelet...
Advanced glycation end products (AGE) are formed in long-lived matrix proteins by a nonenzymatic reaction with sugar. The presence of AGE in beta 2-microglobulin-amyloid fibrils of dialysis-related amyloidosis, one of the characteristic features of which is an accelerated bone resorption around amyloid deposits, was recently demonstrated. This suggested a potential link of AGE in bone resorptio...
Objective(s): Prostate cancer (PC) is the most common cancer in men over 50 years of age. Bone scintigraphy is still performed in many institutions at the time of primary diagnosis. We aimed to evaluate the role of bone scan in the primary staging of PC in regard of different risk groups. Methods: A retrospective analysis of bone scans i...
تقسیم بندی مطالعات عصر سنگ و فلز در ایران، بدلیل آنکه شروع ذوب فلز و استفاده از آن در ایران) با توجه به آنکه در بسیاری از محوطه های مهم استقراری آثار فلزی از بین رفته و چیزی از آنها باقی نمانده است(، نامشخص است؛ در این مطالعه از ترکیبات شیمیایی موجود در استخوانهای باقی مانده از محوطه های باستانی ایران کمک گرفته شده است، تا بتوانیم با توجه به میزان غلظت عناصر نادر موجود در استخوان، به طبقه بندی ...

OBJECTIVE The purpose of this study was to investigate whether skeletal maturation using cephalometric radiographs could be used in a Brazilian population. MATERIAL AND METHODS The study population was selected from the files of the Oral Radiological Clinic of the Dental School of Piracicaba, Brazil and consisted of 128 girls and 110 boys (7.0 to 15.9 years old) who had cephalometric and hand...
mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...
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...
