We observed that flowing helium at moderate pressures accelerated DNA-coated microprojectiles to velocities suitable for penetration of cells in intact plant tissues. The flowing helium principle… (More)
The effect on dentinal hypersensitivity from the use of a dentifrice containing 5.0% potassium nitrate, 1.3% soluble pyrophosphate, 1.5% PVM/MA copolymer, and 0.243% sodium fluoride in a silica base… (More)
BACKGROUND
We conducted a 3-year, double-blind, randomized, placebo-controlled study to determine whether the positive effects of hormone/estrogen replacement therapy (H/ERT) on postcranial bone… (More)
The hydrolysis of ATP was measured in the presence of schistosome homogenates and various cations. The enzyme was stimulated strongly by either Ca2+ or Mg2+. Na+ added to the activation by Ca2+. A… (More)
BACKGROUND
Our objective was to test the association between cemento-enamel junction, alveolar-crest distance (CEJ-AC, as measured on digitized vertical bite-wing radiographs) and postcranial bone… (More)
OBJECTIVE
To determine the correlations among morphologic operations (MO) values and the correlations among gray-level values for regions of interest (ROIs) placed at various locations on digital… (More)
BACKGROUND
We set out to determine whether morphologic measurements extracted from digitized images of bite-wing radiographs correlated with lumbar and femoral bone mineral density (BMD) measurements… (More)
BACKGROUND
The relationship between loss of radiographic alveolar bone height and probing attachment loss has been studied by a number of investigators, with mixed results. Recent studies have found… (More)
Every organization must monitor and evaluate the performance of its marketing strategies. The health care marketer must continually develop effective measures related to outcomes so that marketing… (More)
