We modelled the population phenology of the diamondback moth (DBM), Plutella xylostella (L.) (Yponomeutidae) with a simple degree day model implemented using DYMEX, a population dynamics modelling program. Predicted and observed developmental periods of DBM reared under field conditions during the months of October 1999 to February 2000 at Forthside Research Station, Tasmania (which is in the t...

A fiber based bend sensor using a uniquely designed Bend-Sensitive Erbium Doped Fiber (BSEDF) is proposed and demonstrated. The BSEDF has two core regions, namely an undoped outer region with a diameter of about 9.38 μm encompassing a doped, inner core region with a diameter of 4.00 μm. The doped core region has about 400 ppm of an Er2O3 dopant. Pumping the BSEDF with a conventional 980 nm lase...

Bone marrow mononuclear cells (BMCs) are suitable for bone tissue engineering. Comparative data regarding the needs of BMC for the adhesion on biomaterials and biocompatibility to various biomaterials are lacking to a large extent. Therefore, we evaluated whether a surface coating would enhance BMC adhesion and analyze the biocompatibility of three different kinds of biomaterials. BMCs were pur...

STUDY DESIGN A case controlled study with prospective data collection. PURPOSE To evaluate the early influence and the final consequence of demineralized bone matrix (DBM) on auto-local bone as a graft enhancer in posterior lumbar interbody fusion (PLIF). OVERVIEW OF LITERATURE DBM is known as an osteoinductive material; however, it has not been clearly recognized to enhance auto-local bone...

The aim of the present study was to construct functional tissue-engineered bone with cell sheet technology and compare the efficacy of this method with that of traditional bone tissue engineering techniques. Canine bone mesenchymal stem cells (BMSCs) were isolated using density gradient centrifugation and then cultured. The BMSCs were induced to differentiate into osteoblasts and cultured in te...

Dibenzoylmethanate replaces the bridging triflate ligands in uranium triflate polyoxo-clusters and cleaves the U(12)O(20) core yielding the new [U(6)O(4)(OH)(4)(eta-dbm)(12)] dibenzoylmethanate (dbm(-)) cluster which slowly dissociates into a monomeric complex. This reactivity demonstrates the importance of bridging ligands in stabilizing uranium polyoxo-clusters.

The receiver operating characteristic curve is a popular tool to characterize the capabilities of diagnostic tests with continuous or ordinal responses. One common design for assessing the accuracy of diagnostic tests involves multiple readers and multiple tests, in which all readers read all test results from the same patients. This design is most commonly used in a radiology setting, where th...

STUDY DESIGN A randomized, controlled animal study. PURPOSE To investigate the effectiveness of fusion and new bone formation induced by demineralized bone matrix (DBM) strips with jelly strengths. OVERVIEW OF LITERATURE The form of the DBM can make a difference to the outcome. The effect of different jelly strengths on the ability of DBM to form new bone is not known. METHODS Forty-eight...

BACKGROUND Injectable calcium sulfate is a clinically proven osteoconductive biomaterial, and it is an injectable, resorbable and semi-structural bone graft material. The purpose of this study was to validate the clinical outcomes of injectable calcium sulfate (ICS) grafts as compared with those of a demineralized bone matrix (DBM)-based graft for filling in contained bony defects created by tu...

Orthopaedic surgeons continue to search for cost-effective bone graft substitutes to enhance bone repair. Teriparatide (PTH 1-34) and demineralized bone matrix (DBM) have been used in patients to promote bone healing. We evaluated the efficacy of PTH and DBM in healing a critical sized femoral defect in three lineage-specific transgenic mice expressing Col3.6GFPtopaz (pre-osteoblastic marker), ...
