Objective(s): Recently, bone-avid radiopharmaceuticals have been shown to have potential benefits for the treatment of widespread bone metastases. Although 177Lutriethylene tetramine hexa methylene phosphonic acid (abbreviated as 177Lu- TTHMP), as an agent for bone pain palliation, has been evaluated in previous studies, there are large discrepancies between the obtained results. In this study,...

Objective(s): Adipose derived stem cells (ADSCs) can be engineered to express bone specific markers. The aim of this study is to evaluate repairing tibia in animal model with differentiated osteoblasts from autologous ADSCs in alginate scaffold. Materials and Methods: In this study, 6 canine’s ADSCs were encapsulated in alginate and differentiated into osteoblasts. Alkaline phosphatase assay (A...

background: diabetes has become the next most widespread disease after cancer. recent studies have found that diabetes and moderate to severe vitamin d defi ciency are associated with reduced bone mineral content; therefore administration of vitamin d may correct these conditions. the purpose of this research is to compare the effect of vitamin d administration on bone to implant contact in dia...

Alteration of the geometrical surface configuration of cortical bone allografts may improve incorporation into host bone. A porous biodegradable coating that would maintain immediate structural recovery and subsequently allow normal graft healing and remodeling by promoting bony ingrowth could provide an osteoconductive surface scaffold. We investigated the feasibility of augmenting cortical bo...

abstract introduction : conjugated linoleic acid (cla) has been shown to positively influence on calcium and bone metabolism in experimental animals and cell culture, but there are limited human data available. material and methods : this double-blind, placebo-controlled trial study was done on 76 healthy post-menopausal women (aged 55.1) which randomly assigned to receive daily four cla capsul...

background: tumors involving the hand skeleton are rare. however, a basic knowledge of hand tumors is necessary for every clinician. this is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. methods: this study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, imam khomeini hospital in tehr...

Currently available non-invasive clinical methods for diagnosing osteoporosis are mainly associated with ionizing radiation. Ultrasonic assessment of bone disease is a more recent technology. A theoretical explanation for the relationship between ultrasonic parameters and bone structure is necessary. Thus, two types of bone samples of perspex (HAP) and perspex-glass beads were produced. Ea...

introduction radiographs provide unique information about the status of periodontium and permanent records of condition of bone throughout the course of the disease. interproximal images record the distance between the cementoenamel junction and the crest of the interradicular alveolar bone, more accurately. the aim of this study was to investigate the effect of different vertical angles of x-r...
