This higher polarity is partially compensated for by an excess of aromatic amino acids (Hegemann et al., 2001; Sineshchekov et al., 2002; Suzuki et al., 2003). 2. Transport activity To study the transport activity of ChR1 and ChR2, both proteins were expressed in Xenopus laevis oocytes...
并给定这些形式工具,Ladusaw就可以去论证像“any”、“every”、“at all”这样的负极词(negative polarity items)出现的可能性将最好用语义来解释:复极词可以出现在向下蕴含(单调递减)函数的论元中,这个洞见在早先由Fauconnier (1975a,b)提出,更多细节见第19章。 在Ladusaw的工作之后,Ladusaw与Linebarger间进行...

The syn thesized compound (4) has a low boundary value of polarity but within the normal range of flexibility, as well as low saturation (Figure 3). Thus, compound 4 corresponds to Lipinski's rule (Table 1) but has limited oral bioavailability. The BOILED-Egg is a graphical display of ...
In consideration of solubility, an organic solvent having relatively high polarity (e.g., ethanol or methanol) may be appropriately added to such a water-insoluble solvent, and the thus-prepared organic solvent mixture may be employed. No particular limitation is imposed on the mixing proportions ...
