This paper outlines a risk assessment of a lead-contaminated residential site in Lake Macquarie, New South Wales, near the Pasminco Metals-Sulphide lead and zinc smelter. The assessment includes a hazard identification and a dose-response assessment based on recent research findings; an exposure assessment based on two interrelated indicators, soil/dust(More)
Purified prostaglandin endoperoxides (PGG2 and PGH2) and hydroperoxides (15-OOH-PGE2) as well as fatty acid hydroperoxides (12-OOH-20:4, 15-00H-20:4, and 13-OOH-18:2) were examined as effectors of soluble splenic cell guanylate cyclase activity. The procedures described (in the miniprint supplement) for the preparation, purification, and characterization of(More)
OBJECTIVE To determine the incidence, clinical characteristics, and risk factors associated with the first culture-proven episode of sepsis among neonates in a neonatal intensive care unit (NICU).

Enzyme replacement therapy for lysosomal storage disorders has made an important contribution to improving the quality of life of affected patients. The treatment, however, is invasive and onerous, involving weekly or biweekly intravenous infusions of product over a 3-4 h period. Such therapy can be extremely disruptive of normal family life and the(More)
The hydrolysis of cGMP by phosphodiesterase was conducted in [18O]water to determine the site of bond cleavage and the stoichiometry of 18O incorporation into 5'-GMP. Three different forms of phosphodiesterase including a calmodulin-calcium-dependent enzyme in its basal and activated states were examined. The hydrolysis of cGMP catalyzed by each of the(More)
