Since spontaneous diffusion of RFP did not occur in non-infected, RFP-transfected (not shown) and, most importantly, in rA75/17red Hko/Hcomp-infected canine brain cell cultures, pre-existing channels between normal astrocytes, if such exist at all, are presumably not employed for nucleocapsid transfer from one cell to another.
Chemical studies on still-heavier elements await the discovery of longer-lived isotopes (if such exist and can be synthesized).
Where public pressure would be useful is targeting wavering Democratic senators and those few Republicans willing to listen to reason, if any such exist.

Ideas are the direct "objects" of perception, whereas it is via our ideas that we only indirectly perceive extra-mental objects (assuming such exist) (Kenny 1968, Wilson 1978, Chappell 1986).
However, we consider the dynamically generated RDF graph an advantage of OpenTox services, and, moreover, it does not preclude linking dynamically generated resources with equivalent resources that have stable identifiers, if such exist.
Physicians, the courts, parents, and caretakers need to be aware of the latest medical and surgical options available, the current applicable laws in each state if such exist, and the ethical guidelines to determine what treatment option is in the best interests of the patient.
More to the point, comparatively few bans, moratoria, or even talk of such exist in most of the state.
