2007 ). A large number of industries other than oil and gas are associated with the emission of S compounds that include food production, artificial fiber synthesis, paper and pulp manufacture, and sewage treatment. Both inorganic and organic reduced S are notorious for foul-smelling air pollution. Hence, the elimination of the sulfide species is highly important. The typically used method for this purpose in oil and gas industries employs sulfide scavengers ( Yang et al. 2014 , Groysman 2017 , Gat-2014–04 ). Scavengers are of different types and can be applied to

Efficacy of antioxidants in scavenging ROS in different cell death models Having shown that ROS are generated in all four cell death models, though with different kinetics and intensities, we next investigated the capacity of four ROS scavengers with different mechanisms of action to scavenge ROS. As

Introduction We have recently identified several bioactive compounds that act as radical scavengers from a microorganism culture and from a vegetable [1–3]. Free radicals cause oxidative stress in various organs in the human body and also induce inflammatory diseases, whereas those present in food can cause deterioration of the nutrient factor as a result of lipid peroxidation [4, 5]. We have focused on the identification of new bioactive compounds based on their radical scavenging activity. Our screening program involves high-performance liquid chromatography
