But, if simply increasing the concentration of Er3+ in the NPs, the luminescence shows a nonlinear relationship with the concentration of Er3+ and sometimes the luminescence intensity even decrease with the augment of Er3+, due to the influence of energy migration and concentration-quenching effects at higher concentrations.
Element migration and concentrations are observed with SIMS imaging.
Above all, the negative contributions from the electro-migration and concentration diffusion to the acid-recovery process were firstly isolated by means of a series of well-designed experiments.
The paper gives landscape-geochemical characteristics (processes of migration, dispersion and concentrations of elements in soils) of the Russian part of the Amur Basin.
Importantly, the effects of glutamate on NG2 cell proliferation, migration and differentiation are concentration dependent.
However, it blocked migration and invasion at concentrations that inhibited FGFR and PDGFR signaling.
E7080 does not significantly affect tumor cell proliferation but can inhibit their migration and invasion at concentrations that both inhibit its known targets and are achievable clinically.
Although the evidence for direct effects of E7080 on tumor proliferation are not compelling we did see significant effects of E7080 on tumor cell migration and invasion at concentrations that both inhibit its known targets and are achievable clinically.
Positive correlations between individual changes in chemotactic activity (peak neutrophil migration) and blood neutrophil concentrations (% change from baseline) 5 h after exercise were found after both TW1 (r = 0.630, p = 0.13, n = 7 subjects) and TW2 (r = 0.655, p = 0.056, n = 9 subjects).
The results of this study suggest that these novel conjugates are able to affect the metastatic potential of this breast cancer cell line by inhibiting both migration and adhesion at concentrations at which DHA, EPA or propofol alone are not effective.
Overall, these results show that acidic or alkaline co-contaminant disposal with uranium can result in complex depth- and time-dependent changes in uranium dissolution/precipitation reactions and uranium sorption, which alter the uranium migration mass, concentration, and velocity.
