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 ...
Reconstructing childhood and adulthood diets from a Caribbean population using stable carbon and nitrogen isotope analysis of dentin and bone collagen
(2012-11-10)
The purpose of this study was to establish stable carbon (C) and nitrogen (N) isotope signatures for the 43 individuals in this study population using bone and dentin collagen, and extrapolate the isotopic data to dietary ...
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. ...
Aspects of infectious agents and cancer : effects of human Papillomavirus 16 and Escherichia coli on the innate immune defense of human keratinocytes
(2012-11-10)
Persistent human papillomavirus (HPV) is the causative agent of cervical cancer and bacterial vaginosis (BV) caused by Escherichia coli (E. coli ) has been implicated as a contributing factor. The innate immune system is ...
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 ...
Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
(2011-07-19)
Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ...
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 ...
