Residential Proximity to Major Roadways Is Associated With Increased Levels of AC133+ Circulating Angiogenic Cells.

Objectives: Previous studies have shown that residential proximity to a roadway is associated with increased cardiovascular disease risk. Yet, the nature of this association remains unclear, and its effect on individual cardiovascular disease risk factors has not been assessed. The objective of this study was to determine whether residential proximity to roadways influences systemic inflammation and the levels of circulating angiogenic cells.

Acrolein exposure is associated with increased cardiovascular disease risk.

Background: Acrolein is a reactive aldehyde present in high amounts in coal, wood, paper, and tobacco smoke. It is also generated endogenously by lipid peroxidation and the oxidation of amino acids by myeloperoxidase. In animals, acrolein exposure is associated with the suppression of circulating progenitor cells and increases in thrombosis and atherogenesis.

College students' exposure to tobacco marketing in nightclubs and bars.

Objective: to examine whether a college student's exposure to tobacco marketing in nightclubs and bars was affected by the presence of a smoke-free law.

Participants: a random sample (N = 478) of students participated in the survey (no smoke-free law, n = 240; smoke-free law, n = 238). The analysis was limited to students who reported being in nightclubs and bars (n = 171).
