Benign-by-Design: Synthesis of Engineered Silicon Nanoparticles and their Application to Oil Sands Water Contaminant Remediation
Download2013-11-29
Iqbal, M., Veinot, J.G.C., Purkait, T.K., Goss, G.G.
Oil sands are naturally occurring mixtures of sand or clay, water, fine silts, and bitumen. The oil sands extraction process consumes large volumes of water (i.e., ca. 3 barrels of fresh water for every 1 barrel of oil). Following the extraction of bitumen from the oil sands, a tailings slurry...

Development of a Novel Engineered Bioprocess for Oil Sands Process-Affected Water and Tailings Fines/Bitumen/Water Separation
Download2014-12-09
Gamal El-Din, M., McPhedran, K., Islam, M.S.
The oil sands bitumen extraction process results in the creation of waste products including oil sands process-affected water (OSPW) and mature fine tailings (MFT). Many technologies are currently under investigation to treat these waste products that are currently contained in vast storage...

Freshwater Sponges Have Functional, Sealing Epithelia with High Transepithelial Resistance and Negative Transepithelial Potential
Download2010
Leys, S.P., Goss, G.G., Adams, E.D.M.
Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum [1], [2], are generally believed to lack true...

Iqbal, M., Gamal El-Din, M., Aghajamali, M., Veinot, J.G.C., Purkait, T.K., Goss, G.G., Hadidi, L.
There are many candidate technologies that could be applied to the treatment of oil sands process-affected water (OSPW). Advanced oxidation processes (AOPs) are particularly useful for degrading biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents,...

Mannitol at clinical concentrations activates multiple signaling pathways and induces apoptosis in endothelial cells
Download1998
Vandorpe, D.H., Izumo, S., Malek, A.M., Goss, G.G., Jiang, L., Alper, S.L.
Background and Purpose—Hyperosmotic mannitol therapy is widely used in the clinical setting for acute and subacute reduction in brain edema, to decrease muscle damage in compartment syndrome, and to improve renal perfusion. Though beneficial rheological effects commonly are attributed to...

Na+/H+ exchange activity during phagocytosis in human neutrophils: Role of Fc7 receptors and tyrosine kinases
Download1996
Downey, G. P., Orlowski, J., Goss, G.G., Grinstein, S., Waddell, T. K., Fukushima, T.
Abstract. In neutrophils, binding and phagocytosis facilitate subsequent intracellular killing of microorganisms. Activity of Na+/H ÷ exchangers (NHEs) participates in these events, especially in regulation of intracellular pH (pHi) by compensating for the H ÷ load generated by the respiratory...

Liang, J., Gamal El-Din, M., Estrada, L.P., Tumpa, F., Liu, Y.
The accumulation of mature fine tailings (MFT) in tailings ponds with very slow natural consolidation rate has been a concern for decades. Previous studies and current practices for tailings consolidation focus on the addition of various inorganic and organic additives to reduce MFT production...

Background: The MS4A gene family in humans includes CD20 (MS4A1), FcRb (MS4A2), Htm4 (MS4A3), and at least 13 other syntenic genes encoding membrane proteins, most having characteristic tetraspanning topology. Expression of MS4A genes is variable in tissues throughout the body; however, several...

Review of Health Effects of Naphthenic Acids: Data Gaps and Implications for Understanding Human Health Risk
Download2012-04-11
Gamal El-Din, M., Kindzierski, W., Jin, J.
Oil sands mining involves removal of water from the Athabasca River basin in northeastern Alberta. Water produced during the extraction of bitumen from oil sands is referred to as oil sands process water (OSPW). Information on the likelihood of human exposure to OSPW derived naphthenic acids...
