Race and Superfund site remediation.

Superfund is a federal program established in 1980 to manage the cleanup of hazardous waste sites across the United States. Given the health and economic costs borne by people living near these sites, any demographic disparities within the Superfund program are issues of environmental justice. We investigate whether racial demographics local to a Superfund site are associated with its cleanup status, and if so, how.

Comparative study of the interaction of some meso-substituted anionic cyanine dyes with human serum albumin.

Spectral-fluorescent properties of the meso-substituted anionic cyanine dye 3,3'-di-(γ-sulfopropyl)-4,5,4',5'-dibenzo-9-methylthiacarbocyanine betaine (DMC) were studied in solutions and in the presence of human serum albumin (HSA). The properties of DMC were compared with those of the previously studied meso-substituted anionic dyes 3,3'-di(γ-sulfopropyl)-4,5,4',5'-dibenzo-9-ethylthiacarbocyanine betaine (DEC), 3,3'-di-(γ-sulfopropyl)-9-methylthiacarbocyanine betaine (MTC) and 3,3'-di-(γ-sulfopropyl)-5,5'-diphenyl-9-ethyloxacarbocyanine betaine (OCC), which were studied here in more detail. In aqueous solutions, DMC, like DEC, is prone to dimerization; it also forms H- and J-aggregates.

[Hemostasis in influenza and acute respiratory viral infections in the middle-aged and elderly].

Hemostasis was examined over time in 168 patients with influenza and ARVI. There were 53 elderly patients, 54 senile patients and 4 long-livers. 57 patients under 60 years made up a reference group.
