(A) In CA1, after adjusting for injury, uptake of the dendrimer varied as a function of time (p < 0.05), with decreased uptake in mice injected 6 h after HI. (B) No significant differences in uptake were observed in CA3. (C) In DG, uptake by neurons showed an interaction of injection time and temperature (p < 0.05); uptake of Cy5-D-NAC was greater in hypothermic animals when administered 6 h after HI, at the onset of rewarming (p < 0.05, estimated marginal means ± s.e.m.).
