Using SIFT-MS for detection of beer spoilage bacteria and compounds causing off-flavour in beer
(2014-12-18)
Selected ion flow tube mass spectrometry (SIFT-MS) was used for detection of spoilage bacteria in wort and beer. Samples were analysed in triplicate using SIFT-MS Full Scan mode to identify volatile compounds in the headspace ...
In vitro antioxidant and antibacterial activity of twenty-one Northern Ontario medicinal plants
(2014-01-22)
Aboriginal communities in the northern Ontario region utilize an abundance of locally grown medicinal plants. However, no prior documentation or phytochemical studies on the northern Ontario medicinal plants existed in ...
The cumulative effects of hypoxia and hyperglycemia on cardiac oxidative stress
(2014-01-22)
Hyperglycaemia-induced oxidative stress plays an important role in cardiomyocyte
cell death leading to cardiac dysfunction. Autophagy is an intracellular bulk degradation
process and can be induced by stressors such as ...
Intra-lake and inter-lake variation in copper tolerance in Daphnia from clean and metal-contaminated lakes
(2014-01-22)
The freshwater invertebrate Daphnia can persist in historically metal-contaminated lakes
due to its ability to adapt to metal contamination. Since different Daphnia isolates have been
shown to have varying degrees of ...
The effect of Omega-3 polyunsaturated fatty acid supplementation on lipid composition, oxidative stress, and aldehyde concentrations in rat liver and brain
(2014-01-22)
Oxidative stress is caused by an imbalance between the production and removal of reactive oxygen species (ROS). Polyunsaturated fatty acids (PUFA), due to their multiple carbon-carbon double bonds, react readily with ROS ...
Testate amoebae (thecamoebian) based reconstruction of Lake Simcoe fringe wetland paleoenvironments
(2014-12-12)
Lake Simcoe, Ontario, Canada, a large southern Ontario
glacial lake, has been affected by multiple environmental
stressors throughout its history. This study uses testate
amoebae paleodistribution to reconstruct the ...
Lake trout and their egg predators' ability to locate spawning substrate using olfaction
(2014-01-22)
Lake trout spawning sites, and the substrate on these sites, are structurally unique
in many ways. These sites are generally at the end of the fetch of a lake, close to shore (1
m) and composed of small to medium sized ...
Functional niche differentiation in co-occurring congeneric plants
(2014)
Niche differentiation is argued as one of the mechanisms explaining species coexistence. Despite their sessile nature, similar resource needs and traits to acquire and utilize resources closely related plant species coexist. ...
Adaptive habitat selection by a single celled alga?
(2014-01-22)
Faculty and students in the Department of Biology are bound together by a common interest in explaining the diversity of life, the fit between form and function, and the distribution and abundance of organisms. The research ...
The antioxidant resveratrol down-regulates inflammation in an in vitro model of Pseudomonas aeruginosa infection of lung epithelial cells
(2014-01-22)
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen capable of infecting the lungs and causing severe pulmonary disease in immunocompromised individuals. During the infectious process, P. aeruginosa provokes ...
