Selected ion flow tube-mass spectrometry in plant volatile compound analysis
(2009-07-20)
Four monoterpenes and two monoterpenoids, (+)- and DL-limonene, (1S)-(3) carene, terpinolene, cineol and rose oxide, respectively, were studied using selected ion flow tube-mass spectrometry. Specifically, the reactions ...
Predicting mixing trends in mine-receiving waters using water quality modeling
(2016)
Complete mixing of the water column of lakes is important to ensure that nutrients and dissolved oxygen are replenished and equalized throughout the lake. This ensures that organisms within the lake at all trophic levels ...
Factors influencing thermal variability and fish distribution in small boreal steams / by Lisa McKee.
(2010)
The spatial variability of stream temperature is an important component of habitat within streams providing optimal temperatures for foraging and thermal refugia for sensitive species such as brook trout. Riparian shading ...
Extraction of phytochemicals betulin and betulinic acid from the chaga mushroom and their effect on MCF-7 Cells
(2018)
Chaga mushroom (Inonotus obliquus) grows on birch trees found mainly in temperate regions like
Canada, Northern United States and Siberia. It contains phytochemicals such as betulin and
betulinic acid, which are a ...
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)
Flavobacterium psychrophilum, the causative agent of Coldwater Disease, affects salmonid fish in aquaculture operations worldwide and causes skin lesions which if left untreated results in spinal deformities, spiral swimming ...
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 ...
