Impact of PSMA Targeted Gold Nanoparticles on Prostate Cancer Radiation Bystander Effect
, 2021 Gold nanoparticles (GNPs) are effective radiosensitizers due to their ability to enhance ionizing radiation absorptance and deposit elevated dose in their vicinity. Radiation induced bystander effect (RIBE) expands radiation effects to non-targeted cells

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Subtotal hippocampal resection can leave residual hippocampal tissue, yet the immediate postoperative electrophysiologic evolution of such remnants is unknown. We describe a patient with drug‐resistant temporal lobe epilepsy in whom a hippocampal remnant was continuously monitored using a responsive neurostimulator (RNS) following subtotal ...
