A multiomic approach to paleogenetic investigation of ancient North American bison
(2018)
Twelve ancient bison bone samples from north-central North America were examined using genetic and proteomic sequencing to determine relationships to other bison populations. Mitochondrial DNA sequences suggest a genetic ...
Algal mixotrophic metabolism for the production of lipids
(2018)
The challenges associated with the use of conventional sources of crude oil increase the
demand for alternative fuel sources. Biofuels offer the chance of replacing the depleting fossil
fuels. However, the food versus ...
Improved anti-melanoma and anti-melanogenic effects of birch bark triterpenes delivered in ethosomes
(2018)
North American birch species of the boreal forest contain significant amounts of pentacyclic triterpenes in their outer bark. Betulin (BE) and betulinic acid (BA), pentacyclic triterpenes readily extracted from outer birch ...
Studies on water quality of aquaculture farms with an emphasis on Flavobacterium psychrophilum and UV treatment
(2016)

Efficacy of bacteria and caffeine as indicators of anthropogenic waste in freshwater systems
(2018)
With urban sprawl and intensified agriculture, nutrient loading of waterways has become a pressing issue across southern Ontario. Domestic wastes are more likely than other wastewater sources to be associated with the ...
A combined method for establishing keratinocyte cultures from cervical biopsy specimens and creating patent-derived 3-dimensional organotypic raft cultures
(2018)
High-risk types of human papillomavirus (HPV) are responsible for nearly all instances of cervical cancer, and a significant proportion of head and neck cancers. Studying HPV in the laboratory requires the cultivation of ...
Secoisolariciresinol diglucoside reduces cell death and upregulates antioxidants in cardiac iron overload
(2016)
Iron is essential to many biological and metabolic processes used in all organisms, but excess iron can result in complications such as cirrhosis, diabetes, and heart failure. Cardiac iron overload has been linked to ...
Limnology of two proximal pit lakes after twenty years of intense flooding
(2001)
Two adjacent pit-lakes, Caland and Hogarth, formed after the flooding of open pit iron
mines near Atikokan, Ontario, Canada, were examined for their water quality relationships
and potential to support aquaculture. ...

This thesis synthesizes three papers on the ecology of the riparian zone vegetation found
along small coldwater streams in northwestern Ontario. The objectives of this thesis were
1 ) to describe the biodiversity and ...
Understorey plant regeneration after wildfire in the boreal borest of Northwestern Ontario / by Alexander J.A. Zeller.
(2007)
