Summary: The Omicron variant of the SARS-CoV-2 virus has caused global panic due to its high infectivity and ability to escape vaccines. A comprehensive analysis using an artificial intelligence model and antibody structure analysis reveals that Omicron may be over 10 times more contagious than the original virus and has an 88% likelihood of vaccine escape. This study highlights the importance of developing mutation-proof vaccines and antibodies.

Summary: Reactive oxygen species (ROS) are highly reactive and dangerous by-products that can cause oxidative cell death, but they also play a beneficial role in regulating biological processes. ROS are generated in various cell compartments of plants and require the action of antioxidants to scavenge them. This review provides a comprehensive overview of the fate of ROS in plants, their role in stress response, and their interaction with other signaling molecules/pathways.

Summary: Curcumin, isolated from Curcuma longa, has potent tumor-suppressor activity and can decrease the adverse impacts of cisplatin (CP) while enhancing its antitumor activity. Curcumin reduces ROS levels to prevent apoptosis in normal cells, inhibits inflammation, and reduces various toxicities caused by CP. Additionally, curcumin potentiates CP cytotoxicity and suppresses tumor-promoting pathways to prevent drug resistance.
