Evidence for alternative quaternary structure in a bacterial Type III secretion system chaperone
(BioMed Central, 2010-07-15)
Background: Type III secretion systems are a common virulence mechanism in many Gram-negative bacterial pathogens. These systems use a nanomachine resembling a molecular needle and syringe to provide an energized conduit ...
The utility of direct-current as compared to frequency domain measurements in spectrally-constrained diffuse optical tomography toward cancer imaging
(SAGE Publications, 2011-10-01)
This work investigates, by means of analytical and simulation studies, the performance of spectrally-constrained image reconstruction in Continuous-Wave or Direct-Current (DC) and Frequency Domain (FD) near-infrared optical ...
Response of mid-rotation loblolly pine (Pinus taeda L.) physiology and productivity to sustained, moderate drought on the western edge of the range
(MDPI, 2016-09-14)
The productivity of the approximately 11 million ha of loblolly pine plantations in the southeastern USA could be threatened by decreased water availability in a future climate. To determine the effects of sustained drought ...
Sigma factor n, liaison to an ntrC and rpoS dependent regulatory pathway controlling acid resistance and the LEE in enterohemorrhagic Escherichia coli
(Public Library of Science (PLoS), 2012)
Enterohemorrhagic Escherichia coli (EHEC) is dependent on acid resistance for gastric passage and low oral infectious dose, and the locus of enterocyte effacement (LEE) for intestinal colonization. Mutation of rpoN, encoding ...
Low seroprevalence of antibodies to Toxoplasma gondii in blood donors in central Namibia
(Informa UK Limited, 2014)
Although emphasis has been placed on research relating to human immunodeficiency virus (HIV), tuberculosis and malaria, several researchers in Africa are focusing on other threats to human health, such as neglected tropical ...
Serodetection of Ehrlichia canis amongst dogs in central Namibia
(AOSIS, 2015-06-01)
Ehrlichia canis is a major pathogen in dogs throughout Africa, yet it has not been reported in Namibia. The aim of this study was to determine the seroprevalence of canine ehrlichiosis in central Namibia using the ImmunoComb ...
Limits on anomalous trilinear gauge boson couplings from WW, WZ and Wgamma production in pp[over ¯] collisions at √s=1.96 TeV
(2012-10-26)
We present searches for the anomalous γWW and ZWW trilinear gauge boson couplings from WW and WZ production using lepton plus dijet final states and a combination with results from Wγ, WW, and WZ production with leptonic ...
Spatial heterogeneity increases diversity and stability in grassland bird communities
(Ecological Society of America, 2015)
Grasslands are inherently dynamic in space and time, evolving with frequent disturbance from fire and herbivores. As a consequence of human actions, many remaining grasslands have become homogenous, which has led to reduced ...
New design of a lentiviral shRNA vector with inducible co-expression of ARGONAUTE 2 for enhancing gene silencing efficiency
(BioMed Central, 2015-12-08)
Background: RNA interference (RNAi) is a robust tool for inhibiting specific gene expression, but it is limited by the uncertain efficiency of siRNA or shRNA constructs. It has been shown that the overexpression of ARGONAUTE ...
Libraries, long lives, and...Louis L'Amour? Oklahoma 100 year life oral history project
(Oklahoma State University, 2015-06)
