... Arg-HCl in the absence of the chaperone precluded analysis of the effect of this concentration on the protective ability of aB-crystallin. Reduction-induced aggregation of the insulin B-chain Light ... incubated alone (Fig. 2A,C). Addition of Arg-HCl (up to 250 mm) had a negligible effect on the amount of precipitation. Similarly, low and intermediate con- centrations o...

Because nonpronominals contribute ... attentional function. Therefore pitch accented pronominals are mainly interpreted with respect to Cf, for their attentional content. (3) The specific attentional consequences of e...

Conclusions The comparison of apo- and holo-lMb by MD simu- lations reveals a dramatic effect of the heme cofactor, which is seen to stabilize native Mb-like folded confor- mations ... conceiv- ably also contribute to the conformational stability of holo-lMb. Consistently, they are maintained over the 1.5 ns of the simulation (Fig. 2). A comparison of th...
