However, the strength and generalizability of the inferences drawn from this pilot work were constrained by presentation of a small number of scenes that did not vary independently along all four dimensions of theoretical interest and by inclusion of women displaying only neutral and positive affect.
Immobilization of cytokines such as LIF and stem cell factor (SCF) to maleic anhydride copolymer thin-film coatings proposed by Alberti and coworkers [ 8] investigated control over stem cell fate through spatially constrained ligand presentation that provides quantitative control of the signaling ligands at material-cell interfaces.
Since capsule formation may occlude or otherwise constrain the presentation of cell wall proteins and inhibit the interaction of plasminogen with surface receptors, we compared the plasminogen-binding activities for capsular, hypocapsular, and acapsular cells.
These data, together with results from Figures 4C and D, suggest that capsule formation may occlude or otherwise constrain the presentation of cell wall proteins and inhibit the interaction of plasminogen with surface receptors, although factors other than capsule formation may compromise the ability of stationary phase cells to interact with plasminogen.
This speed instruction was constrained by the rapid presentation of the targets.
The language of those presentations is constrained by the language on the F.D.A.-approved label -- in other words, all the battles over efficacy and sedation at those obscure F.D.A. meetings in the 1980's define the sales vocabulary of the 1990's.
That no objective gold standard exists for the diagnosis of SpA, which is instead based on a composite clinical presentation, constrains the possibilities for the evaluation of the diagnostic accuracy of MRI.
These results suggest that the effect of protective HLAs is not necessarily the result of presentation of particularly constrained epitopes.
During the planning of the museum's exhibits, the foundation had felt constrained by this single line ("a factual presentation of what is known of the terrorists, including their methods and means of preparation").
MHC-II self-antigen presentation by lymph node stromal cells allowed the non-proliferative maintenance of antigen-specific Tregs and constrained antigen-specific immunity.
