Reactive Oxygen/Nitrogen Species and Antioxidant Defenses in Lotus japonicus
Reactive oxygen/nitrogen species (ROS/RNS) are potentially cytotoxic molecules because they can generate oxidative/nitrosative stress. However, ROS and RNS, at concentrations tightly regulated by antioxidants, serve also useful purposes in processes such as organ development, abiotic and biotic stress response and redox signaling. Antioxidant enzymes and metabolites are abundant in plants and p...
متن کاملMorphological Changes in Response to Drought Stress in Cultivated and Wild Almond Species
This study was undertaken to identify morphological changes in young seedlings of 5 Iranian almond species (Prunus dulcis, P. eburnea, P. eleagnifolia, P. haussknechti, and P. scoparia) under polyethylene glycol-induced drought stress. Drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...
متن کاملReactive Oxygen Species and Antioxidant in Seminal Plasma and Their Impact on Male Fertility
Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...
متن کاملRole of Caspases and Reactive Oxygen Species in Rose Bengal-Induced Toxicity in Melanoma Cells
Objective We have previously shown that Rose Bengal (RB) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. To clarify RB-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ROS) were studied in melanoma cells. Material and Methods Human melanoma cell lines, Me 4405 and Sk-Mel-28 were cultured in DM...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
