Cobalt (Co)-doped ZnO nanoparticles have been synthesized at 100 °C using a simple chemical technique, without post-deposition annealing. These nanoparticles are of excellent crystallinity and show a significant reduction in defect density upon Co-doping. By varying the Co solution concentration, it is observed that oxygen-vacancy-related defects are suppressed at lower Co-doping, while the defect density shows an increasing trend at higher doping densities.

Transplants, besides providing neural replacement, also stimulate host regeneration, which could serve as a powerful means to establish functional recovery in CNS insults. Earlier, we have reported the H3-GFP transplant mediated recovery of cognitive functions in the ventral subicular lesioned rats. In the present study, we demonstrate the efficacy of a non-neural fibroblast transplants in mediating host regeneration and functional recovery in ventral subicular lesioned rats.

We have demonstrated in our previous studies that ventral subicular lesion induces neurodegeneration of the hippocampus and produces cognitive impairment in rats. In the present study, the efficacy of transplanted green fluorescent protein (GFP)-labeled hippocampal cell line (H3-GFP) cells in establishing functional recovery in ventral subicular lesioned rats has been evaluated. The survival of H3-GFP transplants and their ability to express trophic factors in vivo were also investigated.
