Among the 131 confirmed DR, 73.3% were background/nonproliferative DR, 2.3% were proliferative DR, and 24.4% had no specification on DR grading.
Yet Nortel's agreement has no such specifications.
The addition of DSL peptide to differentiated cells cultured on collagen substrata (Fig. 1c) had no effect on lineage specification, as shown by flow-cytometry analysis using lineage-specific markers (Fig. 3k).
Injection of the lacZ tracer had no effect on precursor specification (P>0.05, n=4) (Fig. 2F,F′,J).
SOX17 acts cell autonomously, and the presence of mutant cells in embryoids had no effect on hPGCLC specification from wild-type cells.
Removal of Vret from somatic cells had no effect on oocyte specification or localization, or the morphology of the follicle cell epithelium (Fig. 2B).
Expression of XDvl2 increased the number of precursors (P<0.001, n=14) (Fig. 6C,C′,E), whereas Ds1 had no effect on precursor specification (P>0.05, n=13) (Fig. 6D,D′,E).
The current tally doesn't make for easy reading; just 16 of 156 GCSE and A-level specifications due to be taught next September have been signed off, while 14 of 21 subjects have no approved specification at all.
It is also the "reference implementation" of PHP, as PHP has no formal specification, and so the semantics of Zend PHP define the semantics of PHP itself.
The Python language has no formal specification and in fact evolves together with its principal implementation.
