introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

We report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. A 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with Tc-99m hydroxymethylene diphosphonate (HMDP) and single-photon emission computed tomography/computed tomography (SPECT/CT). The lesion was rich in blood flow acc...

background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

Introduction: The physiological process of sternum surgical fracture consolidation in patients undergoing cardiac surgery could be prolonged by the invasion of gram-positive saprophytic bacteria which perpetuates the local inflammatory process despite the standardized aseptic and antiseptic measures in cardiac surgery. In this regard, the topical application of Vancomycin can e...

Introduction: Nasal bone fractures are one of the most common problems in patients who are referred to otolaryngology centers. We aimed to evaluate physical examination, sonography and conventional lateral nasal bone radiography in patients with nasal bone trauma and its relation to intra-operative findings. Methods: This prospective study was performed on 200...

Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).Design- Experimental study.Animals- four mongrel dogs.Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were...

background: for tissue engineering of bone, anatomical and operational reconstructions of damaged tissue seem to be vital. this is done via reconstruction of bone and appropriate biological joint with bone tissues of damaged areas. in this study the condition of biodegradable bed nano fiber phbv and ussc cells were used to accelerate bone repair of damaged area. methods: hollow nanofabrication ...

background osteoporosis and chronic kidney disease are common conditions in older adults, and often occur concurrently. bone disease is caused by increased bone turnover accompanying secondary hyperparathyroidism, and by factors such as bone metabolic disorder accompanying kidney disease and postmenopausal or age-related osteoporosis, even in hemodialysis patients. raloxifene is commonly used f...

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 bone ceme...
