The diversity of sources and long timeframe of accumulation of pollutants creates a jigsaw puzzle for environmental scientists.
The 7-day time point of NGF treatment was selected for further analysis to explore p53 transcriptional activity at the time of highest p53 protein accumulation representing a stable timeframe of p53-DNA occupancy following NGF exposure.
This defines the average time between reproductive events in a lineage, and the timeframe for the accumulation of errors generated during such events.
This behavior was not as prevalent in M. sexta that fed on leaves elicited 2 h prior to the experiment, suggesting that the caterpillars could be responding to a cue specifically associated with the early plant defense response; this timeframe coincides with peak accumulation of JA and JA-Ile.
However, diurnal RBCS expression and light/dark oscillation of RBCS mRNA in an inverse timeframe to the normal daytime accumulation and night mobilisation of leaf carbohydrates previously reported [ 78- 81].
We believe the lack of resolution in the topology of the OC1 phylogeny, both within (Additional file 2: Figure S1) and between species, reflects the fact that HTT events involving this element took place within a relatively short timeframe preventing sufficient time for accumulation of diagnostic mutations.
During a one year timeframe, partial As III) oxidation to As V) and accumulation on poorly crystalline Fe (oxyhydr oxides were promoted by increasing As III) contents, which hindered the transformation of less into more crystalline materials.
The branch lengths separating the major subtypes exceed 100 SNPs, suggesting there were likely at least eight separate introduction events into Canada, as the accumulation of this number of SNPs is unlikely within the timeframe of Holstein-Friesian dairy farming in Canada (1881 to the present) [ 35].
Five sources contributed >4 % to the total ash accumulation for this site in Tokyo across all magnitudes for this timeframe (Isu-Tobu, Hakone, Fuji, Akagi and Oshima; Fig. 10).
It seems clear that as for the cases analysed by Ho et al., we must use data appropriate to the timeframe involved rather than assume a constant rate for accumulation of SNPs.
This supports streamlining nanoparticle internalization in the cell and accumulation of nanoparticle into a certain compartment of interest depending on the timeframe.
