Various particle sizes of demineralized freeze-dried bone allograft (DFDBA) are currently used to treat patients with periodontal osseous defects. However, the effect of particle size on the healing of human intrabony periodontal defects is unknown since there have been no direct clinical comparisons. The purpose of this study was to compare the bony defect(More)
The purpose of this study was to compare the changes in clinical attachment when either a non-resorbable ePTFE membrane or an absorbable collagen membrane was used as a barrier during surgical treatment of class II molar furcation defects. Thirteen patients, mean age 43.2 years, with two comparable class II molar defects were treated using a split mouth(More)
In July of 1999, the department of Academic Technology at Drew University began the search for a trouble-ticket tracking package. After researching several commercially available products, we determined that none offered us the flexibility we needed at a price we could afford. Despite our lack of success in finding a commercially available product, our need(More)
Since the early 90s Drew University has provided basic email services to all students, faculty, and staff, standardizing on IMAP-based email in 1999.

The support structure has evolved with the technology, and now crosses several technology departments including Administrative Computing (AC), Telecommunications (Telecom), Instructional Technology Services (ITS), and Computing & Network(More)
The effect of Mg2+ on Ca2+ bound to glycerinated rabbit psoas muscle was studied by means of a double-isotope technique. The troponin-C content of the fibers was analyzed by quantitative sodium dodecyl sulfate polyacrylamide gel electrophoresis and found to be 0.5 mumol/g fiber protein. In the absence of Mg2+ the fibers bound a maximum of 3.5 mumol Ca2+/g(More)
