Ethics and practice in organ transplantation in patients infected with human immunodeficiency virus.

In sum, much more needs to be known about the issue of transplantation in HIV-infected patients before the current state of extremely limited access to transplantation for these patients can be medically and ethically justified.

Nurses can effect change in this area as informed clinicians, patients' advocates, researchers, and policy makers.

Effects of subsurface heterogeneity on natural bioremediation at a gasoline spill site.

A test cell of 3-m by 6-m located at the mid-point of a gasoline spill site was selected to test the hypothesis that the rate of hydrocarbon biodegradation is influenced by the spatial distribution of the electron acceptors, aqueous geochemistry, and microbial population. Multilevel samplers (MLSs) were installed at four corners of the test cell for groundwater sampling. Sampling ports were placed at 0.
