Non digestible carbohydrates in the diet determine toxicity of irinotecan (CPT-11)/5-fluorouracil in rats independently of β-glucuronidase activity in intestinal lumen
DownloadFall 2012
Aim of this study was to assess effects of non-digestible carbohydrates on the pathobiology of mucosal injury after chemotherapy. Rats bearing colon tumor (n=6/diet) were fed diets including 8% (w/w) as either cellulose, inulin, fructo-oligosaccharide (OligoF), 50:50 (w/w) inulin and oligoF...

Petrophysical properties of bitumen from the Upper Devonian Grosmont reservoir, Alberta, Canada
DownloadFall 2009
The Upper Devonian Grosmont reservoir in Alberta, Canada, is the single largest carbonate bitumen reservoir in the world, with an estimated 400 billion barrels of bitumen in place. The Grosmont bitumen formed from light crude oil via extensive biodegradation, which produced extremely high in-situ...

The evaluation of toxic effects induced by exposure of mammals to oil sands process-affected water and its organic fraction
DownloadSpring 2018
Oil sands process-affected water (OSPW) produced by the surface-mining oil sands industry in Alberta, has been shown to be toxic to a variety of organisms. Much of this toxicity has been attributed to the dissolved organic compounds, primarily naphthenic acids (NAs). Under a no-release practice,...

The impact of various ozone pretreatment doses on the performance of endogenous microbial communities for the remediation of oils sands process-affected water
DownloadFall 2015
In this study, the effects of different ozone pretreatment doses on the performance of endogenous microbial populations in degrading naphthenic acids (Nash and Traver) for the treatment of oil sands process-affected water (OSPW) were evaluated. The results showed that ozonation enhanced the...

Uptake of waterborne selenite, and its toxic effects, in the water flea (Daphnia magna), Westslope cutthroat trout (Oncorhynchus clarkii lewisi) and rainbow trout (Oncorhynchus mykiss)
DownloadSpring 2024
Selenium is an essential element, playing an important role in many physiological processes. However, it possesses a narrow margin between essentiality and toxicity. In aquatic systems, selenium is increasingly identified as a trace element of major concern with levels exceeding regulatory...
