Now-a-days, there is an increased occurrence of various diseases like cardiovascular disease, neurological disorders, cancer, diabetes and autoimmune disease due to the presence of free radicals. Bandyopadhyay et al. [1]. Antioxidant is defined as the agent that neutralizes the effect produced by free radical Fang Y et al. [2]. The antioxidant can be classified into two categories, namely enzym...

The purpose of the current study was to determine possible improvement in soybean plants’ tolerance against vanadium-induced stress response application olive solid waste (OSW) and selenium nanoparticles (Se-NPs), by assessing metabolites plant defense systems. Drawing upon this aim, a pot experiment performed where plants were grown with fertilization treatment (including, control, OSW, Se-NPs...

Abiotic stresses such as drought, cold, salt and heat cause reduction of plant growth and loss of crop yield worldwide. Reactive oxygen species (ROS) including hydrogen peroxide (H2O2), superoxide anions (O2 (•-)), hydroxyl radical (OH•) and singlet oxygen ((1)O2) are by-products of physiological metabolisms, and are precisely controlled by enzymatic and non-enzymatic antioxidant defense system...

Plants respond to various stresses during their lifecycle among which abiotic stress is the most severe one comprising heat, cold, drought, salinity, flooding, etc. take a heavy toll on crop yield worldwide in every corresponding year. ROS has dual role mechanisms where, at high levels, they are toxic cells while same time, molecule can function as signal transducer that activates local well sy...

Arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) are increasingly being used to enhance crop abiotic stress resistance. Common myrtle is an economically important essential oil-producing but knowledge about its drought resistance mechanisms the mitigation potential of AMF PGPR scant. Here, we investigated effects single dual (Funneliformis mosseae, Rhizophagus ...

Skin cells are constantly exposed to reactive oxygen species (ROS) and oxidative stress from exogenous and endogenous sources. UV radiation is the most important environmental factor in the development of skin cancer and skin aging. The primary products caused by UV exposure are generally direct DNA oxidation or generation of free radicals which form and decompose extremely quickly but can prod...

The atricle presents modern data on the composition and role of antioxidant system in human body.The stages components (enzymatic non-enzymatic) are considered, classifications given. Its participation pathogenesis diseases progression has been proven.
