Genotypic and allelic frequencies of SULT1A1 polymorphisms in women receiving adjuvant tamoxifen therapy.

Human sulfotransferase 1A1 (SULT1A1) is involved in the metabolism of a number of substances including 4-hydroxytamoxifen. It has been shown that patients who are homozygous for the variant SULT1A1 *2/*2 have lower catalytic activity. Previous data has suggested that patients with this particular genotype may be at a greater risk of developing breast cancer or not responding to tamoxifen therapy.

Smallpox: residual antibody after vaccination.

Of all the microorganisms and toxins, poxviruses (Orthopoxvirus) have the greatest potential for use by terrorists. These viruses can spread rapidly through the environment following initial infection. In 1980, the World Health Organization Eradication Program discontinued vaccination for smallpox and declared that the disease had been eliminated.

Viral infections of nonhuman primates.

Approximately 53,000 serologic tests and viral isolation studies were performed on 1,700 nonhuman primate specimens for evidence of past and/or current viral infection. Information, other than the requested test, generally was not provided with the specimen. This lack of information does not permit any attempt at interpretation of results.

Detection of Ebola-Reston (Filoviridae) virus antibody by dot-immunobinding assay.

Thirty human and nonhuman primate sera tested at the Centers for Disease Control by enzyme-linked immunosorbent assay (ELISA), immunofluorescent antibody assay (IFA), and Western blotting were retested at the Virus Reference Laboratory, Inc. by the dot-immunobinding assay (DIA). The Ebola-Reston strain of virus received from the Centers for Disease Control was prepared into a suitable DIA antigen as described for other antigens.
