1. Influence of Oxidative Stress on Muscle and Bone
Abstract : Reactive oxygen species (ROS) induce oxidative stress and although are primarily recognized for playing a deleterious biological role, they can be beneficial to cell systems. ROS are extremely short-lived and normally tightly regulated by antioxidant defence systems. READ MORE

2. Determination of biomarkers for lipid peroxidation and oxidative stress : Development of analytical techniques and methods
Abstract : Oxidative stress can be defined as a state of disturbance in the pro-oxidant/antioxidant balance in favour of the former, leading to potential damage. Processes associated with oxidative stress involve reactive oxygen species and radicals and can result in elevated levels of oxidatively modified or toxic molecules that can cause cellular malfunction, and even cell death.

3. Measuring degradation in cable insulation material under realistic operation conditions
Abstract : One of the challenges in laboratory investigation of degradation and ageing of HVDC cable insulation is related to securing, or in other words, imitating the real service environment of the material specimens. So far, the published data refer to experiments conducted in thermo-oxidative conditions, which is not the case during normal cable operation. READ MORE

4. Inborn errors in the metabolism of glutathione
Abstract : Glutathione (GSH) is a tripeptide present in all mammalian cells. It takes part in several fundamental biological functions, including handling of reactive oxygen species (ROS), detoxification of xenobiotics and carcinogens, redox reactions, biosynthesis of DNA and leukotrienes, as well as neurotransmission/neuromodulation.
