Much of organic chemistry is based on the ability of suitably structured chemicals to bind together through the formation of covalent bonds. Biochemistry is replete with exam- ples of enzymatically catalyzed reactions in which normal body constituents can be linked through covalent bonds during the process of intermediary metabolism. The finding that xenobiotic chemicals that enter the body from the environment, are metabolized to highly reactive species, and then covalently react with cellular macromolecules to induce toxic and carcinogenic effects was an observation that spawned the...

This volume presents a discussion of the biological effects produced following the metabolism of xenobiotic chemicals to chemically reactive metabolites, that is, toxic and carcinogenic effects, which have been the basis of all five earlier volumes in this series. In particular, this volume devotes sections to structure-activity relationships, advances in the understanding of the chemistry of reactive metabolites, and the generation and activity of reactive oxygen species with special emphasis on nitric oxide. There are also segments on DNA damage by reactive metabolites and DNA repair,...

The recent surge in media mergers has set off a wave of stories that all hit very close to home. In some cases, the news organizations themselves become news. The formation of communication conglomerates raises profound questions for reporters' lives and work, such as: What is the best way to cover stories of high profile and complexity? Will the new giants broaden both the definition of journalism and the opportunities for journalists to practice their craft? What are the prospects for the new partnership of big news, new media, and big business? The consequences of consolidation vary by...
