Clinical assessment of extrinsic stain removal efficacy with a new Pulsonic toothbrush.
A highly significant reduction (p < 0.001) in mean Lobene composite scores after two weeks was found for both the Pulsonic treatment group and the FlexCare treatment group (median reduction of 94.4% and 90.7%, respectively). Both treatment groups also showed a highly significant (p < 0.001) reductio...
Dermal permeation of biocides and aromatic chemicals in three generic formulations of metalworking fluids.
Comparison of a dentifrice containing 0.243% sodium fluoride, 0.3% triclosan, and 2.0% copolymer in a silica base, and a dentifrice containi...
One-thousand, three-hundred, and fifty-seven subjects (1,357) completed the study. Regarding root caries, at termination of the study the Colgate Total group presented a mean score of 1.14 +/- 1.75 and a +5.6% change from baseline, while the sodium fluoride toothpaste presented a mean of 1.25 +/- 1....
Microwave spectra of mixtures of non-absorbing solid particles and absorbing liquids
We show that microwave spectra can also be sensitive to sample structure at fixed composition which has implications for analytical applications involving samples which are multi-phase mixtures. We have measured microwave spectra for samples containing a constant volume fraction of non-absorbing gla...

Evaluating the similarity of complex drinking-water disinfection by-product mixtures: overview of the issues.
Humans are exposed daily to complex mixtures of environmental chemical contaminants, which arise as releases from sources such as engineering procedures, degradation processes, and emissions from mobile or stationary sources. When dose-response data are available for the actual envir...
Self-assembly of two-component gels: stoichiometric control and component selection.
We investigated the ability of the gel network structure to evolve from mixtures of different aromatic diamines present in excess. We found that these two-component gels assembled in a component-selective manner, with the dendron preferentially recognising 1,4-diaminobenzene (>70 %), when similar co...
Mechanisms of action of two different natural mixtures of persistent organic pollutants (POPs) in ovarian follicles.
These results suggest that: (1) 'Marine mix' is a mixed-type CYP inducer; (2) 'Mjosa mix' is an inducer of ERbeta and CYP2B; and (3) both 'Marine mix' and 'Mjosa mix' stimulate aromatase activity as a consequence of oestradiol secretion through activation of CYP19....
New human data versus estimates of effects of inhaling fission product mixtures.
Recently, data on exposures of humans as well as animals to fission products in plumes emitted by underground Soviet tests have been declassified by the Khazakhstan government and published in English. Similar human intakes of gross fission product mixtures that caused acute prodromal symptoms have...
Determinants of whether or not mixtures of disinfection by-products are similar.
Reactive chemicals have been used to disinfect drinking waters for over a century. In the 1970s, it was first observed that the reaction of these chemicals with the natural organic matter (NOM) in source waters results in the production of variable, complex mixtures of disinfection b...
