Resveratrol has been shown to reverse some of the detrimental effects of metabolic syndrome (MetS). We sought to define the impact of supplemental resveratrol on normal myocardium remote from an ischemic territory in a swine model of MetS and chronic myocardial ischemia. ⋯ Resveratrol supplementation improves regional left ventricular function and preserves perfusion to myocardium remote from an area of ischemia in an animal model of metabolic syndrome and chronic myocardial ischemia.

Studies examining patterns of cancer care before 2000 have shown underuse of postmastectomy breast reconstruction as well as racial and socioeconomic disparities in its delivery. These findings prompted legislation designed to broaden use at the turn of the millennium. However, little is known about trends in these findings over the past decade. ⋯ Although the use of breast reconstruction has increased from 1998 to 2007, it is still underused among many patient populations. Furthermore, racial and socioeconomic disparities in its delivery have persisted or widened. Additional effort is necessary to broaden the use of breast reconstruction and to ensure equitable access to it.

It is hypothesized that activation of extracellular signal-related kinase (ERK) is critical in activating matrix metalloproteinases (MMPs) during abdominal aortic aneurysm (AAA) formation. ⋯ The MAPK (mitogen-activated protein kinase)/ERK pathway is an important modulator of MMPs during AAA formation. Targeting the ERK pathway by reagents that inhibit either the expression or phosphorylation of ERK isoforms could be a potential therapy to prevent AAA formation.
