Abstract 119: The Effect Of Neuroprotectant NA1 On Early Infarct Growth Following Endovascular Therapy: The REPERFUSE-NA1 Study

Stroke, 2022
Background: Early infarct growth after endovascular therapy (EVT) may lead to unfavorable outcomes despite successful reperfusion. The REPERFUSE-NA1 study replicated the preclinical NA1 experiment by investigating the effect of NA1 on early DWI ...

Correlation between enhanced lattice distortion and volume fraction of polar nanoregions in quenched Na1/2Bi1/2TiO3–BaTiO3 ceramics

, 2021
Quenching has been established as a viable method to increase the depolarization temperature in (100-x) Na1/2Bi1/2TiO3–xBaTiO3 (NBT–xBT). The proposed hypothesis of a stabilized ferroelectric order would entail changes in the polarized volume.
