Oxygen-derived free radicals have been shown to play a role in many forms of cell injury. A role for free radicals has recently been demonstrated in the mortality of a rat/sepsis model. The purpose of ...

Accumulation of misfolded oxidant-damaged proteins is characteristic of many diseases and aging. To understand how cells handle postsynthetically damaged proteins, we studied in Saccharomyces ...
