However, metal-oxide nanoparticles (NPs), such as cerium oxide (CeO2) and yttrium oxide (Y2O3), with the property of free radical scavenging demonstrated beneficial effects in the alleviation of oxidative stress biomarkers. The aims of this study include evaluating beneficial effects of CeO2 NPs, Y2O3 NPs, and their combination against diazinon-induced oxidative stress in different tissues of brain, heart, lung, kidney, liver, and spleen. Eight randomized groups of 6 adult male Wistar rats were formed. Each group of rats administered a different combination of diazinon, CeO2 and Y2O3 NPs daily and levels of oxidative stress markers, such as reactive oxygen species (ROS), lipid peroxidation (LPO), total thiol molecules (TTM) and total anti-oxidant power (TAP) and catalase enzyme, were measured after 2 weeks of the treatment. Measurements of the mhese nanoparticles reduce oxidative stress, it should be borne in the design of the study that additional doses of these substances reverse the beneficial effects. Cinnamic acid (CA), also known as 3-phenyl-2-propenoic acid, is a naturally occurring aromatic fatty acid found commonly in cinnamon, grapes, tea, cocoa, spinach and celery. Various studies have identified CA to have anti-proliferative action on glioblastoma, melanoma, prostate and lung carcinoma cells. Our objective was to investigate the molecular mechanism underlying the cytotoxic effect of CA in killing MDA-MB-231 triple negative breast cancer cells. We performed MTT assay and trypan blue assay to determine cell viability and cell death, respectively. Comet analysis was carried out to investigate DNA damage of individual cells. Furthermore, AO/EtBr assay and sub-G1 analysis using flowcytometry was used to study apoptosis. Protein is
