The selective activation of PDE4D splicing variants by β1AR and β2AR signaling confirms the selectivity observed in the physical association of β1AR with PDE4D8 and the preferential sequestration of PDE4D5 to the β2AR by β-arrestin (Baillie et al, 2003).
These channels have different shaped openings that determine the shape selectivity observed in H-ZSM-5.
This has potential implications for the life of the catalyst bed and the activity and selectivity observed.
The competitive adsorption between trans-C4H7 and cis-C4H7 also contributes to the unusual selectivity observed.
Compound 61 demonstrated JNK3 IC50 = 77 nM and retained the excellent broad kinase selectivity observed for the series.
The low O2/N2 selectivity observed in the composite membrane with 30% silicalite loading should be due to silicalite-PFA interfacial defects [30].
These adsorption properties are therefore considered to contribute to the high activity and selectivity observed on Co-ZSM-5.
The high selectivity observed at finer scales appeared to be the result of limited spatial perception and experience due to the species' characteristic slow mobility.
These counterions lower the apparent charge of the channel, which may underlie the decrease in selectivity observed experimentally with increasing salt concentrations.
The selectivity observed on the traditional full mushroom compost for the growth of A. bisporus is based on the presence of thermophilic fungi developed during phase II pasteurization (Straatsma et al. 1989, 1994; Wiegant et al. 1992).
Therefore, the improvement in C5+ selectivity observed for Ru-promoted catalysts as compared to unpromoted catalyst may be due to the Ru enrichment on the cobalt crystallite surface [4, 5].
