The main weaknesses of PCR-based assays are that they do not preserve tissue morphology, may require sample macro- or microdissection to enrich for tumor content, heterogeneity can be missed and contamination with normal or ductal carcinoma in situ may lead to both false-negative and false-positive results.
Cardiac CTA is useful in non-coronary applications, including evaluation of the thoracic aorta, cardiac valves and other aspects of cardiac morphology that may require surgical or percutaneous repair.
Longer epochs tend to give more complex IF morphology and, therefore, may require more complex FM laws and computational power.
Both developmental and functional constraints limit the range of observed changes in morphology, and these limits may require more complex models than were implemented here.
The apparent clustering of swarm types suggests that krill biomass surveys and ecosystem investigations may require stratified survey design, in response to varying 3-D swarm morphology, variation that may be driven in turn by environmental characteristics such as bathymetry.
However, when analysing subgroups of nodules dependent on size and morphology, the cut-off of 25% may be challenged, as smaller size and irregular nodules may require a higher cut-off.
To this end, we reasoned whether the progression from LCIS to ILC may require an increase in c-Src activity and a concomitant dedifferentiation of epithelial morphology.
arcticola/ pacifica groups suggests, in part, that the taxonomic status of these subspecies may require revision, although we recognize that other factors are important for defining subspecies (e.g., morphology, behavior, etc.; Haig et al. 2006).
That may require legislation.
Cloning may require some horsepower.
