MINI-SYMPOSIUM Free radicals and redox signalling in cardiovascular disease
T he generation of reactive oxygen species (ROS) is an inevitable consequence of life in an aerobic environment. ROS are characterised by their high chemical reactivity and include both free radicals (that is, species with one or more unpaired electrons, such as superoxide (O2 ) and hydroxyl radicals (OH)), and non-radical species such as hydrogen peroxide (H2O2). In health, there is a balance ...

متن کاملImmuno-spin trapping of protein and DNA radicals: "tagging" free radicals to locate and understand the redox process.
Biomolecule-centered radicals are intermediate species produced during both reversible (redox modulation) and irreversible (oxidative stress) oxidative modification of biomolecules. These oxidative processes must be studied in situ and in real time to understand the molecular mechanism of cell adaptation or death in response to changes in the extracellular environment. In this regard, we have d...

متن کاملFormation of Redox Active Nanoselenium on Reactions of Oxidizing Free Radicals with Selenourea
Reaction of reactive oxygen and nitrogen species with selenourea were studied using different fast reaction techniques. In all these cases elemental selenium were produced as one of the reaction product. The size of the elemental selenium can be controlled to nanometer size by addition of bovine serum albumin or sodium dodecyl sulphate (SDS). The particle size, determined by dynamic light scatt...
