He emphasizes the role of oxidative stress and contends that most diseases caused by oxidative stress are caused by chemicals and other factors.
Oxidative stress and reactive oxygen species like superoxide anion and hydrogen peroxide, decrease sperm motility as well as membrane integrity due to increase in membrane lipid peroxidation (LPO).
This is referred to as oxidative stress.3,4 Oxidative stress is thought to take part in the etiopathogenesis of many systemic diseases, including cardiovascular diseases.5,6 Limited studies have investigated the association between slow flow and oxidative stress so far.7-9 In this study in patients with CSF, we intended to evaluate the concentrations of total oxidative status (TOS), oxidative stress index (OSI) and lipid hydroxyperoxide (LOOH) which have antioxidant properties; paraoxonase (PON1), ceruloplasmin (CP), free sulphydryl (SH) groups, and total antioxidant capacity (TAS) levels which have oxidant properties.
Being a metabolic factory of the body, liver is highly vulnerable to oxidative stress induced damage6.
The research suggests that oxidative stress leads to sleep and is also believed to be a reason why we age.
The present study was done to evaluate oxidative stress in GDM by estimating serum levels of MDA (oxidant), serum ceruloplasmin (antioxidant), and uric acid (antioxidant).
Individuals with SCD have high levels of oxidative stress due to the formation of reactive oxygen species such as hydrogen peroxide.
In order for cells to be respond appropriately to oxidative stress and possibly regulate ROS production they need to be able to tell if there are too many ROS being produced; they need to be able to sense the presence of oxidative stress.
Oxidative stress is defined as increase in the intracellular concentration of reactive oxygen species (ROS).
In this study, our goal was to determine the relation between oxidative stress and acute pancreatitis.
New strategies designed to attenuate diabetes-induced oxidative stress, through the blockage of reactive oxygen species (ROS) generation and the enhancement of antioxidant-scavenging activity, are revealed in the original research articles published in this special edition.
