... tested on older users, because the behaviour of older users is richer and more complex. But do older and younger users constitute two separate groups, or are there older users that be- have like younger ... due to the lack of corpora for different types of users. In this paper we focus on the behaviour of older vs. younger adults. Most of the wor...

... procedure. The finding that the effect of CoASH depends on the presence of ATP (although not of other NTPs such as GTP and UTP; not shown) suggests that it is indirectly mediated via the formation of ... because of the presence of saccharo- 1,4-lactone, an inhibitor of b-glucuronidase, in the samples where b-glucuronides had to be determined, the amount of b-glucu...

... propionyl-CoA in the DmcsA-strain, the activity of methylisocitrate lyase is twice as high than that of the wild-type. The addition of acetate to these media not only lowered the propionyl-CoA ... elegant way to bypass the inhibition of this synthetase is the transfer of the CoA- moiety from succ inyl-CoA to either acetate or p ropionate. We were able to show the e...
