Introduction: Various therapeutic options such as Calcitonin are suggested for patients with low bone density. However, the efficacy remains uncertain in all patients. C-telopeptide of type I collagen (CTx) is the authentic bone marker which is recently used to assess the bone turnover. This study aimed at revealing the therapeutic effects of Calcitonin on osteopenic women via ...

hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).however, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. hereby, authors report a w...

PURPOSE A 3-dimensional finite element analysis was performed to evaluate the influence of implant type and length, as well as that of bone quality, on the stress/strain in bone and implant. MATERIALS AND METHODS Two types (screw and cylinder) and 4 lengths (9.2, 10.8, 12.4, and 14.0 mm) of titanium implants were buried in 4 types of bone modeled by varying the elastic modulus for cancellous ...

We used a bone marrow transplantation approach to distinguish the activities of bone marrow-derived macrophages from the activities of central nervous system-resident microglia in phenomena associated with axon demyelination and remyelination. We transplanted wild type or germline NG2 null beta-actin-EGFP expressing bone marrow into irradiated wild type or NG2 null recipient mice, followed by a...

Primary hyperparathyroidism associated with multiple endocrine neoplasia type I (hyperparathyroidism/multiple endocrine neoplasia type 1) differs in many aspects from sporadic hyperparathyroidism, which is the most frequently occurring form of hyperparathyroidism. Bone mineral density has frequently been studied in sporadic hyperparathyroidism but it has very rarely been examined in cases of hy...
