And that, even before Dimon's comment yesterday, always seemed improbable, because all of the accounts of the banks' behavior in the years leading up to the crisis suggest that most of them were swept up in housing-market hysteria like everyone else.
It was, however, improbable because virulence of the experimental F. tularensis strain was tested by inoculation of BALB/c mice and provided results standard for this highly susceptible laboratory species [ 19].
In this case, the late Quaternary extinction event might have influence on this pattern only if there was a selective extinction of extreme eurybiomic species (BSI ≥ 5), which seems improbable because most of the extinct South American large mammals were adapted to open environments instead of being very generalist species.
Limitation of current generation by external resistance was improbable because of high anode potential (−221 ± 275 mV) compared to open cell potential (−369 ± 97 mV).
Although Bao et al. [ 12] suggested that the CODH could also be utilized to fix carbon throughout the Wood-Ljungdahl pathway in C. subterraneus subsp. tengcongensis, it is improbable, because the genome of this strain does not present a gene putatively encoding for the key enzyme acetyl coenzyme A synthase (acsB) [ 4].
A possible interaction of pyruvate and βHB with AMPA to explain the protection is improbable, because, judging from the structure of these molecules it is difficult to envisage the possibility of such interaction, especially considering that it should be occurring with both substrates and these molecules differ considerably.
