Collateral Damage from Antigen Receptor Gene Diversification

Chromosomal translocations that juxtapose antigen receptor genes and oncogenes are frequently associated with lymphoid malignancies. In this issue, Robbiani et al. (2008) show that activation-induced deaminase (AID), an enzyme involved in antigen receptor gene diversification, generates DNA double-strand breaks (DSBs) in oncogenes, and Tsai et al. (2008) propose that AID and the recombinase-act...

Understanding Cyber Collateral Damage

INTRODUCTION In conventional (kinetic) U.S. warfare, there exists a standard methodology for identifying and assessing collateral damage (i.e. accidental damage to civilian targets). Indeed, the U.S. Department of Defense (DoD) relies on a governing document that defines the policy regarding unlawful military targets (no-strike targets), and methods for estimating collateral damage from kinetic...

Coronary Collateral Blood Flow

Background. Although aspirin exerts beneficial antiplatelet activity in patients with coronary artery disease, cyclooxygenase blockade produced by aspirin causes a potentially deleterious effect by interrupting endothelial production of prostacyclin. Collateral vessels that develop in response to coronary occlusion display prominent endothelial cell proliferation and undergo vasoconstriction in...
