Nmp4/CIZ suppresses the response of bone to anabolic parathyroid hormone by regulating both osteoblasts and osteoclasts
c-fos Fra-2 osteoclastogenesis
2014/11/6
How parathyroid hormone (PTH) increases bone mass is unclear, but understanding this phenomenon is significant to the improvement of osteoporosis therapy. Nmp4/CIZ is a nucleocytoplasmic shuttling tra...
High Bone Mass in Mice Lacking Cx37 Due to Defective Osteoclast Differentiation
gap junctions connexin37 osteoclast
2014/11/6
Connexin (Cx) proteins are essential for cell differentiation, function and survival in all tissues with Cx43 being the most studied in bone. We now report that Cx37, another member of the connexin fa...
Decreased Autocrine EGFR Signaling in Metastatic Breast Cancer Cells Inhibits Tumor Growth in Bone and Mammary Fat Pad
autocrine signaling bone marrow cells breast cancer
2014/11/6
Breast cancer metastasis to bone triggers a vicious cycle of tumor growth linked to osteolysis. Breast cancer cells and osteoblasts express the epidermal growth factor receptor (EGFR) and produce ErbB...
Defective microtubule-dependent podosome organization in osteoclasts leads to increased bone density in Pyk2−/− mice
podosome organization bone density osteoclast functions
2014/11/6
The protein tyrosine kinase Pyk2 is highly expressed in osteoclasts, where it is primarily localized in podosomes. Deletion of Pyk2 in mice leads to mild osteopetrosis due to impairment in osteoclast ...
Selective cyclooxygenase-2 inhibition prevents bone resorption
Alveolar bone loss Anti-inflammatory agents,non-steroidal Cyclooxygenase inhibitors Periodontitis Radiography dental
2009/10/19
The aim of the present work was to evaluate the effect of a selective cyclooxygenase-2 (COX-2) inhibitor (meloxicam) on the alveolar bone loss progression in experimentally induced periodontitis. Fort...
Comparative therapeutic use of Risedronate and Calcarea phosphorica-allopathy versus homeopathy-in bone repair in castrated rats
Allopathy Homeopathy Calcarea phosphorica Fracture healing
2009/10/19
Osteoporosis, a disease characterized by progressive bone loss, has been the target of several studies in the past few years. It results in a much higher risk for fractures and might cause slower bone...
The influence of ovariectomy,simvastatin and sodium alendronate on alveolar bone in rats
Alendronate Models animal Osteoporosis Ovariectomy Simvastatin
2009/10/19
Bisphosphonates are currently used in the treatment of many diseases involving increased bone resorption such as osteoporosis. Statins have been widely used for the treatment of hypercholesterolemia a...
Comparison of histometric and morphometric analyses of bone height in ligature-induced periodontitis in rats
Histology Alveolar bone loss Periodontium
2009/10/19
The purpose of this study was to compare histologic and morphometric procedures of bone height measurement. Microscopic measurements are the most frequent methods in periodontal studies with animals, ...
Smoking enhances bone loss in anterior teeth in a Brazilian population: a retrospective cross-sectional study
Periodontitis Bone resorption Radiography Smoking
2009/10/16
The aim of the present study was to radiographically evaluate the effect of smoking on bone loss resulting from chronic periodontitis. Periapical radiographs were analyzed of 80 patients with chronic ...
Treatment of Periapical Dental Implant Pathology with Guided Bone Regeneration
dental implant peri-implantitis therapy apical inflammation
2009/6/19
Peri-implantitis is the inflammatory process that takes place around alveolar bone surrounding the dental implant. Unless treated, it may result with the loss of the implant. Another cause of the loss...
Three-dimensional Changes of the Mandible and Alveolar Bone in the Ovariectomized Rat Examined by Micro-focus Computed Tomography
alveolar bone micro-focus computed tomography (μCT) three dimension (3D) osteoporosis ovariectomy
2009/5/27
To clarify the changes of the mandible and alveolar bone in postmenopausal osteoporosis, we examined the changes of structure in mandible and alveolar bone of ovariectomized (OVX) rats. Twelve female ...
Influence of Streptozotocin-induced Diabetes on New Bone Formation by rhBMP-2
rhBMP-2 streptozotocin-induced diabetes bone formation insulin
2009/5/27
We studied bone formation induced by recombinant human bone morphogenetic protein-2 (rhBMP-2) combined with polylactate-polyglycolate-copolymer/gelatine sponge complexes (PGS) at palatal subperiosteal...
