Investigation of the Antioxidant and Cellular Toxicity Activities of Gold Nanoparticles Synthesized Using Extract on a Liver Cancer Cell Line.

Background: Liver cancer is increasing in different parts of the world and is the fourth leading cause of cancer death globally.

Objectives: The present study aims to synthesize and analyze the characterization of gold nanoparticles (AuNPs) synthesized by extract and evaluate their antioxidant and cellular toxicity activity against liver cancer cells (HepG2).

Methods: The synthesized AuNPs were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and fourier-transform infrared spectroscopy (FTIR).

Pulsed electromagnetic field attenuated PTSD-induced failure of conditioned fear extinction.

Objectives: This study aimed to determine whether exposure to pulsed electromagnetic field (PEMF) can impair behavioral failure as induced by PTSD, and also its possible effects on hippocampal neurogenesis. PEMF was used as a non-invasive therapeutic tool in psychiatry.

Materials And Methods: Male rats were divided into Control-Sham exposed, Control-PEMF, PTSD-Sham exposed, and PTSD-PEMF groups.
