Various versions of the fables have substituted species and adapted animals, but Aesop mentioned at least a few cicadas.
By determining the moments of inertia of a sufficient number of isotopically substituted species, it is possible to obtain sufficient data from which to completely determine the structure.
On the other hand, it has been demonstrated that, the through- bond interactions in 2-spiropropane-1,3-diyl and Cl, F, OH substituted species cause the triplet state to be more stable than singlets.
Although acknowledging that threatened species shouldn't be used for dissection, Kambadur Muralidhar, a professor of endocrinology at South Asian University in New Delhi, says that substituting species in dissections for example, using the common walking catfish instead of endangered Scoliodon fish would have addressed the issue.
In order to find contaminated or substituted species in COM1 and COM2, DNA barcoding is one of the best solutions.
Interestingly the lack of CB1R binding observed for N-benzoyl substituted species 72 was in contrast to the data obtained for its N-benzyl substituted counterpart 59 (Ki = 61 nM, Table 4).
We have previously highlighted the deficiencies of directly amine-coupling dansyl groups onto the Dab side chains in semisynthetic preparations of dansyl-polymyxin B. Analysis of these semisynthetic dansyl-polymyxin B preparations revealed the existence of mono-, di-, tri-, and tetra-dansyl substituted species.
One hundred-fold dilutions of serum samples were tested for anti-HEV of the IgG and IgM isotypes as reported previously, substituting species-specific secondary antibodies where necessary.
However, it would be difficult to substitute those species for annual grain commodities, because they are much more difficult to harvest, transport, store and process mechanically.
