Analysis of covariance revealed significant differences between the slopes (b) of the regression lines (p < 0.001) for nanoparticle exposures of different concentrations.
The growth inhibition of the cell biomass of Raphidocelis subcapitata during 72 hrs of exposure to different concentrations of AgNWs and AgNPs are shown in Figure 7.
The viability of cells was evaluated after 24 h of exposure to different concentrations of DOX.
Open image in new window Fig. 1 The percentage mortality of different instar larvae of Agrotis segetum, following exposure to different concentrations of infective juveniles (IJs) of nematodes under laboratory conditions (Petri plate bioassay).
Open image in new window Fig. 3 The percentage mortality of fourth-instar larvae of Agrotis segetum following exposure to different concentrations of infective juveniles (IJs) of nematodes under laboratory conditions (soil inoculation method).
Generally the larvicidal activity increased slightly with the increase in the time of exposure except for CMAD which was found to be inactive even after 72 h of larvae exposure to different concentrations of this extract.
Additionally, the literature reviewed does not provide any clear tendency as to the effects of different concentrations of exposure: epidemiological studies using linear models did not provide an exposure effect threshold.
In this study, we synthesized novel Ca7Si2P2O16 ceramic powders for the first time by the sol gel method and investigated the biological performance of PDLCs after exposure to different concentrations of Ca7Si2P2O16 extracts.
It appears worthwhile to develop quantification tools that indicate, on the basis of the transcriptome as phenotypic descriptor, how big a developmental insult is, and that allow the ranking of unknown drugs, or of different concentrations or exposure times of one given drug (Waldmann et al. 2014).
