One likely reason for the poor development of IVP embryos is the excessive exposure of oocytes and embryos to reactive oxygen species (ROS). These molecules are produced as a normal by-product of energy generation; however, excess accumulation of ROS during the IVP of oocyte and embryo culture...
2.5Reactive oxygen species Reactive oxygen speciesare oxygen-containing chemicals with reactive properties. Some examples include O2•-, H2O2, and HO•. An accumulation of reactive oxygen species is consideredoxidative stress. This accumulation can either occur by an overproduction of reactive oxygen ...
7.6.4Increase in Reactive Oxygen Species ROS are derivatives of oxygen that arise in oxygenated conditions and comprise hydrogen peroxide (H2O2), hydroxyl ions (OH−), and superoxide anions (O2−) (Yang et al., 2009). ROS production andoxidative stressinitiation is the crucial biomarker of ...
During the infection process of bacteria, type III effectors are secreted into the plant cell (Büttner and He2009). These effectors primarily interrupt the host’s defense pathways and/or activate theSgenes for disease development (Yang et al.2006; Zaidi et al.2018). Therefore, bothSgenes an...
general idea lies on the functional property of hormones for regulation of reactive oxygen species (ROS). It is found that ROS can induce the pro-coagulant process and the increase of the ROS level can induce SMS proliferation which causes thrombosis. β-Estradiol is a female hormone which has...
In plants, immunogenic cell death has been broadly termed hypersensitive response (HR). HR involves generation of reactive oxygen species (ROS) and elevation of intracellular Ca2+levels (Fig.1) and is often caused by activation of members of the intracellular nucleotide-binding domain leucine-rich ...

Molecular agents may link the events of tendon degeneration and ineffective tendon healing with the production and persistence of reactive oxygen species within both the intra- and extra-cellular milieu of the tendon tissue [40]. The reactive oxygen production is strongly influenced by lifestyle facto...
Introduction Production of reactive oxygen species (ROS) is one of the fundamental characteristics of oxygen metabolism across the tree of life. As a consequence, cells have evolved mechanisms, which in normal circumstances efficiently limit the damage these chemicals can cause. However, the balance ...
