A range of potential chemoprotective agents, most of them natural dietary constituents, has been examined for ability to modulate both phase I (cytochrome P450 1A1, 1A2, 2B1/2, 2C11, 2E1, 3A, 4A) and phase II drug metabolizing enzymes (glutathione S-transferases, in particular subunits Yc2 and P, aflatoxin B1-aldehyde reductase and quinone reductase) in rat(More)
Indole-3-carbinol (I3C) was examined for its ability to inhibit aflatoxin B1 (AFB1)-induced hepatocarcinogenesis in male Fischer rats when administered either before or after the carcinogen. After 13 weeks, animals pretreated with I3C (0.5% in the diet) for 2 weeks prior to administration of AFB1 and with continuing treatment during exposure to the(More)
Reduced intestinal CD4 T cell numbers and gastrointestinal disease are common features of acquired immunodeficiency syndrome (AIDS). Duodenal lymphocyte densities and mucosal addressin cell adhesion molecule (MAdCAM)-1 expression were analyzed in patients with AIDS after highly active antiretroviral therapy (HAART). Compared with human immunodeficiency(More)
gamma-Glutamyl transpeptidase (GGT) is normally absent from adult rat hepatocytes but is induced by a range of xenobiotics, including carcinogens and chemoprotective agents. As many as six mRNA species for this enzyme have been described in both rat and mouse, with various degrees of tissue specificity. These originate from one gene and have separate(More)
This study showed that nonsearchers and searchers are different from each other on almost every measure that was applied. Research on and experience with searching adult adoptees should not be applied to nonsearching adult adoptees. Likewise, research on and experience with nonsearching adult adoptees should not be generalized to searchers . The results of(More)
The purpose of this study was to describe the career patterns and job satisfaction of Ontario university and college nurse educators. A descriptive survey design was employed using mailed questionnaires. The sample comprised 60 nurse educators, 30 from three universities and 30 from three colleges. Forty-four returned the completed questionnaire, giving a(More)
The purpose of this study was to determine if the Dalhousie University School of Nursing's curriculum enabled its graduates to meet the terminal objectives of the programme and to determine if these objectives were consistent with the requirements of their employers. An explorative, descriptive design using qualitative and quantitative data were employed(More)
