Recently the time frame for standard treatment of acute stroke with IV tissue plasminogen activator was expanded from 3 h to 4.5 h from ictus onset [4].
Whole blood specimens were shipped at ambient temperature to ICON Central Laboratories within the previously established 48-hour stability time frame for standard hematology assessment and flow cytometry determinations [data on file].
5 Because cancers may not show up until a rodent's third year of life, corresponding to the time when cancers also are more likely to appear in humans, the two-year time frame for standard bioassays may reduce the likelihood a carcinogenic chemical will be identified, says James Huff, associate director for chemical carcinogenesis at the National Institute of Environmental Health Sciences.
The lag time between when such decisions are taken and when their effect on earnings is evident exceeds the time frames of standard financial models, so the potential for damage to the company and future shareholders, not to mention society more broadly, can easily go unnoticed.
Moreover, these differences were detectable in the time frame of a standard OGTT and correlated with the differences in glucose kinetics between the two groups.
After a baseline sample, the optimal time for breath collection was between 1 and 3 h after the oral glucose load, similar to the time frame of a standard OGTT.
The comparison of similarities among groups for a long-term evaluation was performed by using the type strain of each PFGE profile of each time frame as internal standard.
Over this time frame, according to the standard data, methane scores 25 (meaning that one tonne of methane will cause the same amount of warming as 25 tonnes of CO2), nitrous oxide comes in at 298 and some of the super-potent F-gases score more than 10,000.
Because individuals could have submitted more than one grant application during our sample time frame, we estimated all standard errors used in test statistics by treating the data for each applicant as a cluster.
Since many employers don't want or can't afford to pay overtime, work hours have come to fall within a standard time frame of 9 a.m.-ish to 5 p.m.-ish, give or take.
