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 ...

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 ...

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. ...

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 ...

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 ...

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 ...

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 ...

Paraquat (PQ), one of the most commonly used herbicides worldwide, is hightly toxic to humans and exposure can result in severe clinical situations with no effective treatments available. The toxicity of PQ has been ...

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 ...

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 ...
