Percentile levels are divided into categories with descriptive labels based on prior test findings from different populations, normal and impaired.
Among a pool of four purchased siRNAs against ROCK2 and LIMK1 (Qiagen, Hilden, Germany), the most effective siRNAs were chosen based on prior testing in cell culture.
We chose a phosphate buffering system to set pH of the sample to 7.4 based on prior testing and in accordance with other published buffering methods [ 4, 31].
The value of N for a given shape, designated as the skip factor, was based on prior testing that established what spacing would provide equally recognizable shape patterns.
The investigators determined the dominant pollutant for each site based in part on prior testing or historical use of a site, then took samples to measure levels of the pollutant, typically in only one environmental medium.
The mutation profiles of these samples were known based on prior testing using the Ion Torrent Personal Genome Machine (46-gene hotspot panel), Sanger sequencing, or fluorescence in situ hybridisation (FISH).
The principal investigator and study administrator will review the existing patients' database for hemoglobin level and ejection fraction on prior test results, existing chronic obstructive pulmonary disease (COPD), angina, and history of heart-attack, before contacting the patients.
In 31.8% of discordant couples the infected partner reported being HIV-uninfected based on a prior test.
Patients were identified as likely sporadic hemangioblastomas based on (1) prior testing that was negative for germline VHL mutations by sequencing of the coding regions (exons 1 3), (2) lack of family history of hemangioblastomas or VHL disease, and/or (3) lack of other stigmata of VHL disease, such as renal cancer, pheochromocytoma, or retinal angiomas.
We also obtained information on prior diagnostic tests leading to CRC diagnosis including colonoscopy and other screening tests.
