Key Players

Our common knowledge on oxidative stress has evolved substantially over the years, being focused mostly on the fundamental chemical reactions and the most relevant chemical species involved in human pathophysiology of oxidative stress-associated diseases. Thus, reactive oxygen species and reactive nitrogen species (ROS and RNS) were identified as key players in initiating, mediating, and regulating the cellular and biochemical complexity of oxidative stress either as physiological (acting pro-hormetic) or as pathogenic (causing destructive vicious circles) processes. The papers published in this particular Special Issue of Cells show an impressive range on the pathophysiological relevance of ROS and RNS, including the relevance of second messengers of free radicals like 4-hydroxynonenal, allowing us to assume that the future will reveal even more detailed mechanisms of their positive and negative effects that might improve the monitoring of major modern diseases, and aid the development of advanced integrative biomedical treatments.

Ionizing Radiations

Objective: In the living organisms, deleterious effects produced by ionizing radiations. Human exposure to ionizing radiations increased enormously because of rapid technological advancements. There is a need to protect humans against such effects of ionizing radiation. Protection against the deleterious effects of ionizing radiations by radioprotectors was studied, which may be of great help for human application. Present study was conducted to evaluate the modulating efficacy of prolonged administration of Aloe vera extract against gamma irradiation-induced toxicity in mice. Methods: Animals were given Aloe vera leaf extract orally 1000 mg/kg body weight/d for 15 consecutive days before radiation exposure (0.5, 3 and 5.5 Gy gamma radiation). Results: Mice were autopsied at day ¼, 1, 3, 5, 10 and 20 after irradiation to evaluate the radio modulator effect in terms of the hepatosomatic index. Conclusion: Aloe vera extract has a beneficial protective effect against radiation-induced oxidative stress.

Pathological Conditions

: Increased applications of pesticides mainly in agriculture and public health has resulted in increased chances of human exposure to pesticides. Chronic exposure to pesticides has been implicated in several human diseases including cardiovascular diseases. Cardiovascular diseases are broadly used for various heart pathological conditions including defect blood vessels, and they include myocardial infarction, atherosclerosis, stroke, cardiomyopathy, coronary heart disease etc. In this review, the association between human exposure to pesticides and development of cardiovascular diseases was discussed using epidemiological and laboratory data. The toxicokinetics of pesticides in humans was reviewed, as well as the risk factors for cardiovascular diseases. The important role of oxidative stress, and principally the induction of reactive oxygen species as the signaling molecules for various signaling pathways involved in pesticidesinduced cardiovascular disease was discussed.

Acid Toxicity

Abiotic stresses cause plant growth inhibition, damage, and in the most severe cases, cell death, resulting in major crop yield losses worldwide. Many abiotic stresses lead also to oxidative stress. Recent genetic and genomics studies have revealed highly complex and integrated gene networks which are responsible for stress adaptation. Here we summarize the main findings of the papers published in the Special Issue “ROS and Abiotic Stress in Plants”, providing a global picture of the link between reactive oxygen species and various abiotic stresses such as acid toxicity, drought, heat, heavy metals, osmotic stress, oxidative stress, and salinity.
