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 ...
Macrophyte Community Dynamics in Lake Simcoe’s Fringe Wetlands: Potential use as Biological Indicators of Water Quality
(2016)
Indices have been developed using macrophytes and water quality parameters to detect
the impact of anthropogenic disturbance on coastal wetlands of the Great Lakes, but such an index
does not currently exist for Lake ...
Does fire severity difference create divergent plant communities in black spruce-Kalmia forests of eastern Canada?
(2009-06-25)
After fire, some conifer-ericaceous plant communities in Western Europe and eastern
North America have demonstrated divergent succession from traditional conifer stand
replacement to Ericaceae-dominated community states. ...
The effect of secoisolariciresinol diglucoside on oxidative stress and inflammation in cardiac iron overload
(2013-02-01)
Chronic cardiac iron overload directly correlates with cardiac dysfunction and
may ultimately cause heart failure. Although recent studies have suggested that altered
calcium homeostasis and increased reactive oxygen ...
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 ...
Safety from predators or competitors? Interference competition leads to apparent predation risk
(2013-02-01)
Prey often react to predation risk by foraging preferentially in safe, rather than risky, patches. Yet prey also must deal with the negative effects of competition for the same patches. The pattern of patch use can mimic ...
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 ...
Cystathionine γ-lyase and hypoxia : implicating hydrogen sulfide in the hypoxic stress response
(2012-11-10)
Hydrogen sulfide (H2 S) has emerged as a novel and important gasotransmitter for the cardiovascular system, where it is generated mainly by cystathionine γ-lyase (CSE). Abnormal metabolism and functions of the H2 S/CSE ...
