Owttrim, George W., Magee, Wendy C., Yu, Esther, Chamot, Danuta
The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock...

A LexA-related protein regulates redox-sensitive expression of the cyanobacterial RNA helicase, crhR
Download2006
Colvin, Kimberley R., Owttrim, George W. , Patterson-Fortin, Laura M.
Expression of the cyanobacterial DEAD-box RNA helicase, crhR , is regulated in response to conditions, which elicit reduction of the photosynthetic electron transport chain. A combination of electrophoretic mobility shift assay (EMSA), DNA affinity chromatography and mass spectrometry identified...

Chronic Fatigue Mechanisms in Autoimmune Diseases: Lessons from Primary Biliary Cholangitis and Systemic Sclerosis
DownloadFall 2023
Systemic sclerosis (SSc) is an autoimmune disease affecting the body's connective tissues, resulting in progressive fibrosis and vasculopathy. In some cases, individuals with SSc may also develop primary biliary cholangitis (PBC), another autoimmune disease characterized by damage to their...

Serpe, Michael J., Gao, Yongfeng, Zhang, Qiang M., Ahiabu, Andrews
A series of pyridine-functionalized poly (N-isopropylacrylamide)- based microgels were synthesized. Subsequently, a structured photonic device was fabricated by sandwiching the microgels between two thin Au layers, and their response to CO2 investigated. We show that devices show an optical...

Comparative analysis of two phenotypically-similar but genomically-distinct Burkholderia cenocepacia-specific bacteriophages
Download2012
Stothard, Paul, Dennis, Jonathan J., Lynch, Karlene H.
Background Genomic analysis of bacteriophages infecting the Burkholderia cepacia complex (BCC) is an important preliminary step in the development of a phage therapy protocol for these opportunistic pathogens. The objective of this study was to characterize KL1 (vBBceSKL1) and AH2 (vBBceSAH2),...

Conditional, temperature-induced proteolytic regulation of cyanobacterial RNA helicase expression
Download2014
Owttrim, George W., Tarassova, Oxana S., Chamot, Danuta
Conditional proteolysis is a crucial process regulating the abundance of key regulatory proteins associated with the cell cycle, differentiation pathways, or cellular response to abiotic stress in eukaryotic and prokaryotic organisms. We provide evidence that conditional proteolysis is involved...

Cyanobacterial RNA Helicase CrhR Localizes to the Thylakoid Membrane Region and Cosediments with Degradosome and Polysome Complexes in Synechocystis sptrain PCC 6803
Download2016
Fahlman, Richard P., Owttrim, George W. , Rosana, Albert R. R., Whitford, Denise S.
The cyanobacterium Synechocystis sp. strain PCC 6803 encodes a single DEAD box RNA helicase, CrhR, whose expression is tightly autoregulated in response to cold stress. Subcellular localization and proteomic analysis results indicate that CrhR localizes to both the cytoplasmic and thylakoid...

Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shock
Download2009
Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Carvalho, Wildemar S. P., Wei, Menglian, Ikpo, Nduka, Gao, Yongfeng, Serpe, Michael J.
Reports in the literature on the development of new chemical sensing technologies have been growing steadily in number for years. For example, a Web of Science topic search using the term “Chemical Sensing” revealed that over 8 000 papers were published in 2015–2017, with over 40 000 citations to...
