Intense emission peaks of Eu(DBM)3Phen (DBM and Phen are dibenzoylmethane and 1,10phenanthroline, respectively) in the microcapsules containing molecules of quaternary ammonium chitosan (QACS) and sodium alginate are observed. The microcapsules are assembled by using CaCO3 particles as template cores by the layer-by-layer (LbL) technique. Observation of microcapsules by the fluorescence mode an...

We demonstrate a flip-chip bonded modified uni-traveling carrier (MUTC) photodiode with an RF output power of 0.75 W (28.8 dBm) at 15 GHz and OIP3 as high as 59 dBm. The photodiode has a responsivity of 0.7 A/W, 3-dB bandwidth > 15 GHz, and saturation photocurrent > 180 mA at 11 V reverse bias.

Introduction RTI Biologics, Inc. (RTI) currently produces allograft demineralized bone matrix (DBM) paste products that are manufactured under strict aseptic conditions using single donors. All donors are subjected to rigorous screening, prior to processing, to ensure that no transmissible pathogens are present in donor material. In addition, a terminal sterilization procedure has been introduc...

Study Design Prospective, cohort, non-inferiority study. Purpose This study evaluated the clinical and radiological outcomes of interbody fusion using a combination of demineralized bone matrix (DBM) and hydroxyapatite (HA). Overview of Literature The use of autografts remains a gold standard in lumbar interbody fusion, but the limited availability and donor site morbidity encourages the us...

Denial-of-Service (DDoS) attack is a serious threat in Internet. We propose a bit marking concept to identify and drop the DDoS attack packets. Bit marking is a variation of the packet marking technique that modifies packet headers at each router. However instead of storing the router information in the packets, bit marking alters one or more bits in the marking field. The bit marking process d...

OBJECTIVE Solid bone fusion is an essential process in spinal stabilization surgery. Recently, as several minimally invasive spinal surgeries have developed, a need of artificial bone substitutes such as demineralized bone matrix (DBM), has arisen. We investigated the in vivo bone growth rate of DBM as a bone void filler compared to a local autologous bone grafts. METHODS From April 2014 to A...

The aim of the present study was to compare the radiographic and clinical outcomes of DBM injection and conventional treatment during tibial lengthening over an intramedullary nail in adult patients with short stature. Twenty-nine patients were randomized to receive DBM injection (n = 14) or conventional treatment without any injection (n = 15) and evaluated. The outcome was measured on the bas...

A bone defect resulting from open bone trauma may easily become infected; however, the administration of efficacious systemic antibiotics cannot be performed at safe levels. Previous studies have investigated anti-infective biomaterials that incorporate into bone and facilitate the direct application of high-concentration local antibiotics. In the present study, the effect of a novel porous com...

OBJECTIVE The high risk of nonunion represents a challenge in vertebral surgery, thus stimulating new strategies to improve fusion rates. We investigated the effect of 2 different bone grafts and amniotic fluid application on radiologically and histologically evaluated vertebral fusion in an experimental rat model. MATERIALS AND METHODS Forty-eight 24-week-old Sprague Dawley rats were include...
