An academic, business, and community alliance to promote evidence-based public health policy: the case of primary seat belt legislation.

An academic, business, and community alliance comprising 285 organizations, including 43 national groups represented on a Blue Ribbon Panel organized by the U.S. Secretary of Transportation, targeted Arkansas, Florida, Mississippi, Minnesota, Tennessee, and Wisconsin for high involvement/intervention consisting of community organization and other political action to support passage of primary seat belt laws.

Submicrometer spatial resolution of metal-enhanced fluorescence.

Enhanced fluorescence emission intensity from fluorescein was observed on glass slides covered with thin films of silver nanoparticles using a confocal laser-scanning microscope. The silver nanoparticle film increased the emission intensity of fluorescein by an average of at least three-fold in the area studied. Statistics are given on the enhancement of individual areas of the silver particle film with a resolution of approximately 210 nm.
