Sentence examples for half lives between from inspiring English sources

All four analogues were found to be stable in phosphate buffer at pH 7.4 and 37 °C and were good substrates of E. coli nitroreductase with half lives between 7 and 24 min at pH 7.0 and 37 °C.

Modelling process dynamics in all three tissues simultaneously allows us to use information in the brain and muscle data sets to increase the precision of the parameter estimates in the liver model beyond that which we would have using the liver data alone, and to assess the difference in liver mitochondrial half lives between control and DR mice more rigorously.

The other isotopes have much briefer half lives lasting between milliseconds to seconds.

The median half life of these transcripts was ∼2.9 hr with 80% of the transcripts decaying with half lives of between 1.6 and 5.0 hrs (Figure 1B).

Alfentanil and remifentanil are very fast equilibrating opioids with equilibration half-lives between plasma and effect site of about 1 minute.

The difference in the elimination half-lives between the test products was not significant, suggesting that the elimination of nicotine from blood is not affected significantly by the difference in the nicotine absorption sites.

Enzymatic hydrolysis was very fast in the case of 2-pyrrolidino-, 2-piperidino- and 2- 4-methylpiperazino -ethyl esters, whereas methyl, ethyl, morpholinoethyl and branched 2- 4-methylpiperazino -ethylre considerably more stable (half-lives between 41 and 116 min, compared to <5 min).

When injected into mice, SA129, SA138, and SACTR displayed plasma half-lives between 42 and 47 h, considerably longer than that of small synthetic compounds or antibody fragments, but still shorter than that of full-length monoclonal antibodies (Supplementary Fig. 11a and Supplementary Table 11).

Conclusions: The differences in calculated turnover rates may correspond to effects of feeding or differences in half-lives between exogenous and endogenous albumin.

The removal of progestagens was lower for both pairs (similar chemical structures) PROG and MEDRO than LEVO and NORE, i.e. 48 to 87% with half-lives between 2.1 and 44 min compared to 78 to 97% with half-lives between 2.7 and 5.6 min, in Milli-Q and wastewaters at pH 6.0-8.2, respectively.
