(University of Waterloo, 2012-04-25)Bienertia sinuspersici is one of the three currently known land plants which perform C4 photosynthesis without the conventional dual-cell system, but rather through intracellular compartmentation of organelles and enzymes ... -
Characterization of the Conformation and Internal Backbone Dynamics of a-Polyglucans by Pyrene Excimer Fluorescence
(University of Waterloo, 2021-11-23)The conformation and internal backbone dynamics (IBD) of several pyrene-labeled polysaccharides (Py-PSs), namely Py-Amylopectin, Py-Glycogen, Py-Dextran, and Py-Pullulan, were successfully examined with a combination of ... -
A characterization of the controls of the nitrogen and oxygen isotope ratios of biologically-produced nitrous oxide and nitrate in soils
(University of Waterloo, 2011-08-02)Nitrous oxide (N₂O) is a potent greenhouse gas, an important driver of climate change, and its concentration in the atmosphere is rising at an unprecedented rate. Agriculture is the leading contributor of all the anthropogenic ... -
Characterization of the Distribution of Pyrene Molecules in Confined Geometries with the Model Free Analysis
(American Chemical Society, 2017-12-21)Evidence is provided showing that global Model Free Analysis (MFA) of monomer and excimer fluorescence decays of pyrene dissolved in aqueous solutions of sodium dodecyl sulfate (SDS) provides the same structural and dynamic ... -
Characterization of the Downstream Effects of the Rainbow Trout (Oncorhynchus mykiss) Chemokine, CK-2 on Macrophages
(University of Waterloo, 2010-05-25)Chemokines are chemotactic cytokines that have the ability to attract leukocytes and guide them via a concentration gradient to sites of injury/infection. These small, basic proteins are secreted when induced and act on ... -
Characterization of the expression and function of <em>Rana catesbeiana</em> HSP30 and <em>Xenopus laevis</em> HSP27
(University of Waterloo, 2006)Exposure of cells to environmental or chemical stressors will initiate the heat shock response, which is mediated by heat shock proteins. Heat shock proteins are molecular chaperones which are classified by size into six ... -
Characterization of the FHA domain involved in Saccharomyces cerevisiae dNTP regulation.
(University of Waterloo, 2018-04-26)Over 2000 Forkhead-associated (FHA) domain-containing proteins exhibiting diverse functions, such as kinases, phosphatases, and transcription factors, have been identified to date in both eukaryotic and prokaryotic organisms. ... -
Characterization of the Interactions Between DNA and Oppositely Charged Species by Fluorescence
