On the other hand, the existing specimens are exposed to wear and tear.
Then, the optimal biopsy locations are determined in a feature selection formulation, so that biopsy outcomes (either cancer presence or absence) at those locations could be used to differentiate, at the best rate, between the existing specimens having different (high vs. low) CV/GS values.
The two existing specimens were originally preserved in alcohol, but though this can discolour specimens, it is not probable that it could turn green to blue.
From a mechanistic point of view, viral infections can very well explain many of the hallmark features of early diabetes, the difficult task is now to focus on novel methodologies that are capable of dissecting the few existing specimens in depth and establish conclusive associations between pathology and viral presence or traces thereof.
The trial protocol or observational study plan sets out the research hypothesis, existing specimens, and new assays that are required, as well as data analysis and delivery expectations.
For this reason, we focus here on ancillary studies that involve simply the analysis of frozen, existing specimens.
Existing specimens at the CDC Poxvirus Laboratory (tissues from Egypt, Italy, and England) were reexamined by using modern molecular techniques.
Future investigations, based upon either existing specimens from the last outbreak or newly collected specimens from any future outbreak, should focus on whether an association exits between SARS superspreading events and coinfection with other respiratory viruses.
Existing specimens of mathematics represent all the major eras the Sumerian kingdoms of the 3rd millennium bc, the Akkadian and Babylonian regimes (2nd millennium), and the empires of the Assyrians (early 1st millennium), Persians (6th through 4th centuries bc), and Greeks (3rd century bc to 1st century ad).
Palæontologist Martin Glaessner finally, in 1959, made the connection between this and the earlier finds and with a combination of improved dating of existing specimens and an injection of vigour into the search many more instances were recognised.
Amplification and sequencing of the extended 1.5-kb fragment of the matK gene, encompassing the standard barcode regions, from these additional plant samples and our existing specimens confirmed our earlier conclusions derived using the matK56F and matK1027R primers.
