Characterization of the altered gene expression profile in early porcine embryos generated from parthenogenesis and somatic cell chromatin transfer
Download2014
Dobrinsky, John, Zhou, Chi, Dixon, Walter T., Dyck, Michael K., Stothard, Paul, Foxcroft, George R., Tsoi, Stephen, Verstegen, John
The in vitro production of early porcine embryos is of particular scientific and economic interest. In general, embryos produced from in vitro Assisted Reproductive Technologies (ART) manipulations, such as somatic cell chromatin transfer (CT) and parthenogenetic activation (PA), are less...

Characterization of the cold stress-induced cyanobacterial DEAD-box protein CrhC as an RNA helicase
Download2000
Owttrim, George W., Yu, Esther
We have shown previously that CrhC is a unique member of the DEAD-box family of RNA helicases whose expression occurs specifically under conditions of cold stress. Here we show that recombinant His-tagged CrhC, purified from Escherichia coli, is an ATP-independent RNA binding protein possessing...

Characterization of Type-2 Diacylglycerol Acyltransferases in the Green Microalga Chromochloris zofingiensis
Download2018-12-13
Xu, Yang, Falarz, Lucas, Chen, Guanqun
Diacylglycerol acyltransferase (DGAT) catalyzes the last and committed step of the acyl-CoA-dependent TAG biosynthesis and thus is a key target for manipulating oil production in microalgae. The microalga Chromochloris zofingiensis can accumulate substantial amounts of triacylglycerol (TAG) and...

The THEMIS five-probe constellation was launched in 17 February 2007 to study substorms; however its instrumentation and the alignment at distances <1RE among some of the THEMIS probes, particularly in the first period of its mission, provides unique opportunities to study ULF pulsations in the...

CHARACTERIZATION OF X80 AND X100 MICROALLOYED PIPELINE STEEL USING QUANTITATIVE X-RAY DIFFRACTION
Download2018-01-01
Wiskel, J.B., Li, X., Ivey, D.G., Henein, H.
Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic...

Adeeb, Samer, El-Rich, Marwan, Lewicke, Justin, Carey, Jason P., Schofield, Jonathon, Parent, Eric
Sit-to-stand transfer (STS) is a common yet critical prerequisite for many daily tasks. Literature conducted on healthy STS often assume the body to behave symmetrically across the left and right side; yet only a few studies have been conducted to investigate this supposition. These studies have...

Mager, Diana R., Chan, Catherine B., Ambler, Kathryn, Salawi, Hebah, Padwal, Rajdeep S., Ball, Geoff D. C.
Background Severe obesity (SO) in pediatrics has become increasing prevalent in recent decades. The objective of our study was to examine differences in demographic, anthropometric, cardiometabolic, and lifestyle variables in children and youth with SO versus their less overweight/obese (OW/OB)...

Characterizing the performance of ecosystem models across time scales: A spectral analysis of the North American Carbon Program site-level synthesis
Download2011
Black, T.A., Izaurralde, R.C., Lokupitiya, E., Munger, J.W., Schaefer, K., Weng, E., Richardson, A.D., Altaf Arain, M., Luo, Y., Ciais, P., Ricciuto, D.M., Stoy, P.C., Dietze, M.C., Poulter, B., Barr, A.G., Liu, S., Hollinger, D., Tian, H., Suyker, A.E., Verbeeck, H., Price, D.T., Grant, R.F., Peng, C., Baker, I.T., Vargas, R., Anderson, R.S., Tonitto, C., Sahoo, A.K., Chen, J.M., Flanagan, L.B., Riley, W.J., Wang, W., Lafleur, P., Gough, C.M., Verma, S.B., Kucharik, C.J.
Ecosystem models are important tools for diagnosing the carbon cycle and projecting its behavior across space and time. Despite the fact that ecosystems respond to drivers at multiple time scales, most assessments of model performance do not discriminate different time scales. Spectral methods,...

Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgression
Download2012-01-01
Coltman, David W., James, Patrick M. A., Cullingham,Catherine I., Cooke, Janice E. K.
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...
