Desmosomes are large, complex protein assemblies which, at the most fundamental level, facilitate cellular adhesion. On a grander scale, desmosomes, and more specifically desmosomal networks, are critical for the maintenance of tissue integrity. They link the cytoskeletons of adjacent cells...

Genotoxicity and Mutagenicity of Extractable Organics from Oil Sands Process-Affected Water
DownloadFall 2015
Oil sands process-affected water (OSPW) is produced in the surface mining industry during the hot-water extraction of bitumen from oil-sands ore. Its acid extractable organic (AEO) fraction is known to be acutely toxic, but few studies have addressed its genotoxicity or mutagenicity. Here, the in...

Degradation of Recalcitrant Organics in Oil Sands Process Water (OSPW) Using Combined Electro-Oxidation and Electrochemically Activated Peroxymonosulfate (EO-PMS)

Abdelrahman, Ali Satti Abdellatif
In northern Alberta, the bitumen extraction process from oil sands ores consumes large amounts of water, resulting in the generation of huge volumes of oil sand process water (OSPW). Currently, the treatment of OSPW is considered a major challenge facing the oil sands industry. Moreover, among...

Pyranopterin Coordination Controls Molybdenum Electrochemistry in Escherichia coli Nitrate Reductase
DownloadFall 2015
Molybdenum is an essential trace element for most species on the earth. Molybdoenzymes (enzymes containing Molybdenum) play diverse roles in human health, global geochemical cycles, and bacterial metabolism. Interestingly, nitrate reductase (NarGHI) isolated from the common gut bacterium...

Protein kinases are critical players in cell signaling processes and their activity leads to the phosphorylation of substrates, often regulating enzymatic activity. 518 protein kinases are encoded in the human genome, however, there are many features within the catalytic domain of these proteins...

The extraction, transport and refining of crude oil generates a diverse group of contaminants that pose a risk to both fresh and saltwater fishes. Adult fish can detect and actively avoid exposure to these pollutants; however, the embryonic and larval fish cannot outswim a toxic plume and are...

Caspases are a family of enzymes that regulate biological processes, such as inflammation and programmed cell death, through proteolysis. For example, in the intrinsic pathway of apoptosis, cell death signaling involves cytochrome c release from the mitochondria, which leads to the activation of...

Anthropogenic contaminants can impair olfactory responses to natural odorants. In fishes, these impairments may be used as a metric of sub-lethal toxicity. My studies aimed to determine the effects of two contaminant sources on fish olfaction as measured by electro-olfactography (EOG). The...

The oil sands landscape in northern Alberta is interspersed with large tailings ponds that hold wastewater from bitumen mining and extraction processes. Recent monitoring results indicate that annually many thousands of birds, mostly migrating waterfowl, land on the ponds associated with this...

Analysis of goldfish innate immunity following exposure to oil sands process affected water
DownloadFall 2013
The acute and sub chronic effects of oil sands process affected water (OSPW) and its toxic component, naphthenic acids (NAs) were examined. I exposed goldfish for one (acute), or 12 (sub chronic) weeks and examined immune gene expression, macrophage function, the ability of exposed fish to...
