BACKGROUND Bone morphogenetic proteins (BMPs) were first described for their roles in bone formation, but they now also are known to possess additional activities, including those relating to embryogenesis. The objectives of this work were to 1) determine if peri-attachment bovine conceptuses and bovine trophoblast cells (CT1) contain transcripts for BMP2 and 4, an innate inhibitor noggin (NOG)...

Background: After tooth extraction, alveolar bone resorption occurs naturally, followed by remodeling. Alveolar formation is characterized an increase in density and expansion of the trabecular bone. Socket preservation using a combination Moringa oleifera leaf extract demineralized freeze-dried bovine xenograft (DFDBBX) expected to area trabeculae thus accelerate process formation. Purpose: Th...

To take advantage of the by-product catfish bone, gelatin is made as a value added fishery industry, because Gelatin using sapa bovine fish bone has same characteristics gelatin. main ingredient in manufacture marshmallows to improve texture and ebilite. The purpose this study was determine panelists' preference for with addition into conduct chemical quality tests (water content ash content) o...

many materials have been introduced for apexification each having their own advantages and disadvantages. this case report aims to present a new method of apexification using a combination of deproteinized bovine bone mineral (dbbm) and enamel matrix derivative (emd). after irrigating the canal of the maxillary right canine with 2.5 % sodium hypochlorite, a mixture of bio-oss and emd was packed...

in this paper, preparation, bioactivity, and osteoblast cell behavior of cortical bone derived nanobiphasic calcium phosphate (nano-bcp) are presented. the calcined bovine bone samples with the addition of di-ammonium hydrogen phosphate were heated at 700°c for 100 min, and thus nano-bcp with the composition of 63/37 hydroxyapatite (ha)/β-tricalcium phosphate (β-tcp) was produced. scanning elec...

To measure the speed of sound (SOS), most quantitative ultrasound (QUS) devices use the transmission mode, whereby two transducers are placed on opposite sides of the sample. This mode is limited to a few specific skeletal sites because of the varying configuration of bone geometry and varying amounts of overlying soft tissue at most other sites. The aim of this study was to address the depende...

The purpose of this work was to study the influence of screw length and bone thickness on the stability of temporary implants. A total of 96 self-drilling temporary screws with two different lengths were inserted into polyurethane blocks (n = 66), bovine femurs (n = 18) and rabbit tibia (n = 12) with different cortical thicknesses (1 to 8 mm). Screws insertion in polyurethane blocks was assiste...

1,25-Dihydroxyvitamin D3 (1,25-(OH)2D3), the biologically active form of vitamin D3, has been shown to inhibit proliferation and promote monocytic differentiation of leukemic cell lines. In the present communication, we extend these observations to normal bone marrow macrophage precursors, and 1) identify the stage of monocytic maturation wherein the steroid exerts its antiproliferative effect,...

PURPOSE Different biomaterials have been suggested for guided bone regeneration (GBR). These might show the ideal properties to let a new bone formation in the grafted area. Among these ideal features, it is essential their controlled resorption in order to be replaced for new vital bone. Bovine bone has been used widely as a good biomaterial for GBR, however there is still an interesting contr...
