Both structures can be described as intercalates, since they present ac layers of polymer helices alternated to layers of contiguous guest molecules and a guest/monomeric-unit molar ratio of 1/2, as recently observed only for s-PS/norbornadiene molecular complex.
They lead social lives of a complexity that until recently had been observed only in primates.
However, a discordance between in vivo and in vitro immunological tests have been documented in subjects with latent tuberculosis [ 16, 17] and more recently we also observed only a weak concordance between the LST and IFN-gamma production to SLA in household contacts of CL patients [ 24].
Recently, a small but methodologically-rigorous trial focused on suicidal behavior prevention [ 50] observed only nonsignificant differences in suicidal behavior between lithium and valproate.
Recently Kantartzis and colleagues reported that the association between rs6666089 and insulin sensitivity is observed only in more obese, but not in lean individuals [ 25].
Although this species had long been observed, scientists were only recently able to confirm it was entirely separate to other similar dolphins.
Although the domesticated silkworm, Bombyx mori, has long been used in research and textile production, MIT researchers only recently observed that spatial and environmental conditions came into play with the silkworms. .
The eight-Cys framework XXII was only recently observed in conotoxins, but is quite prevalent in T. anilis transcripts and relatively abundant in T e. subulata transcripts, a finding that further supports while there may be commonalities between cone snail and terebrid venoms, the specific cocktail and complexity found in these groups are extremely variable.
Although waves of mitosis traveling at the predicted speed are apparent in a 1974 film of nuclear divisions in an acellular slime mold [ 32], mitotic waves were only recently observed and accurately quantified by Chang and Ferrell [ 33] in frog egg extracts.
Since slow earthquake migration has only recently been observed, we have not yet observed their migration process just before megathrust earthquakes in subduction zones.
