Reactive oxygen species formed in organic lithium–oxygen batteries

Reactive oxygen species formed in organic lithium-oxygen batteries.

Li-oxygen batteries with organic electrolytes are of general interest because of their theoretically high gravimetric energy density. Among the great challenges for this storage technology is the generation of reactive oxygen species such as superoxides and peroxides that may react with the organic solvent molecules and other cell components. The generation of such species has been assumed to o...

Reactive oxygen species are formed in cell culture media.

When studying the effects of oxidative stress on mammalian and yeast cells, we observed that the media without cells generated reactive oxygen species. Mammalian cell media such as RPMI 1640 medium with Glutamax-I (GibcoBRL, Cat. No. 31996) and Dulbecco’s Modified Eagle Medium with Glutamax-I, sodium pyruvate and pyridoxine (GibcoBRL, Cat. No. 31966; DMEM), as well as the yeast extract-peptone-...

Oxidized lipids formed non-enzymatically by reactive oxygen species.

O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

I-3: Reactive Oxygen Species: A Dilemma for

Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
