Nearly two-thirds of patients with known epilepsy were documented as being on either no therapy or monotherapy, so it seems likely there are additional treatment possibilities that could have prevented many of these seizures.
Lastly, the presence of a novel hemoplasma species infecting rats suggests the possibility that there are additional strains or possibly other species of hemotropic mycoplasmas yet to be described.
We can not exclude the possibility that there are additional amino acids that have phospho- or some other post-translational modifications that regulate Sso protein function.
Therefore, while there are clearly contact-independent factors secreted by the VE that enhance myocardial differentiation, our data cannot rule out the possibility that there are additional contact-dependent effects of VE as well.
These findings raise the possibility that there are additional candidate genes that regulated CD133.
Our failure to observe any adult males suggests that the D. melanogaster genome does not harbor additional major-effect HI loci within the regions screened, but this does not exclude the possibility that there are additional factors of minor effect that contribute to hybrid lethality.
A second possibility is that there are additional factors contributing to the minus-end force operating on chromosomes (for example, poleward flux or other minus-end directed motors).
There are additional challenges.
There are additional exceptions.
