Academic journals are periodicals in which researchers publish their findings, mostly the recent ones. Academic journals are typically peer-reviewed journals that publish theoretical discussions and articles that critically review already published work. Academic journals serve as an important forum for researchers and academicians from where they can access important information about recent developments in their field. These journals are the first choice for any in-depth examination of an issue related to science. Science as we know is scarcely imaginable without the academic journal. OMICS Group International Journals fall under the academic category as they strictly adhere to peer-review process and follow the format by publishing mostly the original work. OMICS International journals publish periodically and contain a series of articles in each published issue.
Reactive oxygen species (ROS) including superoxide anion (O2-.) hydrogen peroxide, and hydroxyl radical (OH.), are generated naturally in vivo during metabolic processes and keeps in a balance level in normal living organisms. However, when a body is subject to the environmental or behavioral stressors (pollution, sunlight exposure, cigarette smoking, excessive alcohol consumption, etc,), excess ROS are generated. If the excess ROS cannot be scavenged in time, they would attack and induce DNA, proteins and lipids damage, and impede normal cell functions. In living systems, the deleterious effects of ROS can be neutralized by the endogenous and exogenous antioxidant systems.Antioxidants are synthetic or natural substances that prevent or delay the oxidative damage by scavenging the free radicals. Fruits and vegetables are good sources of high amounts of known antioxidants. Therefore, overproduction of ROS is associated with numerous diseases like cancer and Alzheimerâs disease, as well as aging. The antioxidant capacity was evaluated, by coupling an amperometric sensor for H2O2 detection, obtained by modification of paste carbon graphite electrode with copper, with xanthine oxidase (XOD) immobilized at siliceâxanthine (XA) enzymatic system, as generator of O2- Radicals. The antioxidant capacities of three synthesized molecules were investigated based on an electrochemical sensor using copper modified carbon paste electrode as work electrode.(NgonoThÃ©rÃ¨se Rosie Lauriane, JamilaBouali, RachidaNajih, MostafaKhouili, AbderrafiaHafid and AbdelilahChtaini, Synthesis and Electrochemical Evaluation of Some Organic Molecules as an Antioxidant Agents)
