Control organisms were sampled at several time points during embryonic and larval development until 33 days post-fertilization.
Fig. 1 shows the cortisol content of the fertilized eggs before exposure to air and several time points during recovery.
Membrane samples were imaged by scanning electron microscopy at several time points during in vitro degradation to assess any changes in pore structure.
Levels of BOEs for ten selected cigarette smoke constituents (nicotine, carbon monoxide (CO), benzene, 1,3-butadiene, acrolein, hydrogen cyanide, crotonaldehyde, 4- methylnitrosamino -1- 3-pyridyl -1-butanone [NNK], pyrene, 4- methylnitrosamino -1- 3-pyridyl -1-butanonemeasured at several time points during the study period.
To determine the optimal cycle length, cell numbers were counted at several time points during primary and secondary expansion cycles.
By drawing composite immunological profiles of the different infection groups, our analyses demonstrate that these profiles do indeed distinguish groups at several time points during the first weeks of infection with virulent FIVC.
Aliquots of the spores in either sterile deionized water or germination solution were also transferred into an anaerobic chamber at several time points during a 24 hour period and quantitative cultures were performed.
Ten µl aliquots were transferred into an anaerobic chamber at several time points during a 24 hour period and inoculated into 90 µl of absolute ethanol or sterile deionized water.
However, the increase of explorative activities shortly before the light-dark transition was much more pronounced and advanced by some hours in HR mice compared to the other two lines, resulting in significant differences at several time points during the light phase (KWH-tests: N = 12 for each line, experimental time points: 6, 7, 8, 9, 10, H = 6.1 12.6, df = 2, all p<0.05; see Fig. 3).
Plots from several time points during the course of incubation are presented.
All infants carried S. pneumoniae, H. influenzae and M. catarrhalis at several time points during infancy.
