introduction one of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. metastatic bone disease is the most common form of malignant bone tumors. samarium-153-ethylene diamine tetramethylene phosphonate (153sm-edtmp) as a radiopharmaceutical is used for pain palliation. this radiopharmaceutical usually emits beta particles, which...

background: recently, tissue engineering has developed approaches for repair and restoration of damaged skeletal system based on different scaffolds and cells. this study evaluated the ability of differentiated osteoblasts from adipose‑derived stem cells (adscs) seeded into hydroxyapatite/ tricalcium phosphate (ha‑tcp) to repair bone. methods: in this study, adscs of 6 canines were seeded in ha...

background and aims. recent literature shows that accelerated portland cement (apc) is a non-toxic material that may have potential to promote bone healing. the objective of this study was to histologically evaluate periodontal healing focusing on new bone regeneration following implantation of apc into intra-bony defects in dogs. materials and methods. three-wall intra-bony periodontal defects...

background and aims. autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. the complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (hbmg). the present study was conducted to compare the efficacy of hbmg and autograft on the reconstruction of bone defects in rats. materials and methods. in ...

in this session, we will discuss 7 cases in pediatric musculoskeletal field. these cases will include different aspects of bone and msk disorders in pediatrics such as bone tumors (benign and malignant), bone involvement in metabolic and hematologic disorders, infectious diseases and soft tissue vascular lesions. during this session, we will ask some volunteered radiology residents to explain t...

Dental implants have been studied over the years to replace missing teeth. One of conditions for success is their stability and resistance under applied forces minimal tension in surrounding bone. The purpose this dissertation numerical three-dimensional analysis jaws with mechanical thermal loading by finite element method. For purpose, implant simulations (including ceramic crown, titanium ro...

Objective(s) Bone marrow is the traditional source of human multipotent mesenchymal stem cells (MSCs), but adipose tissue appears to be an alternative and more readily available source. In this study, rat adipose-derived stem cells (ADSCs) were induced to differentiate into Schwann-like cells and compared with rat bone marrow stem cells (BMSCs) for their Schwann-like cells differentiation pote...

The old wishes of people were to regenerate lost tissues of periodontium that this fact is achieved by gen and cell therapy .Periodontal disease is a chronic inflammation around the tooth by microbes that causes destruction of supporting structure of tissue of tooth such as alveolar bone, cementum and periodontal ligament. For treatment of periodontal diseases we can use the biomaterials which ...

the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...

The purpose of this study was to explore the effectiveness combined one-stage reconstruction extensive complex defects lower limb tissues and analyze postoperative complications. Material methods . research involved 25 patients with bone soft tissue extremities. first group included 16 patients, where replacement soft-tissue leg carried out one bone-skin graft. second consisted 9 who, along maj...
