Arsenic-induced changes in the gene expression of lung epithelial L2 cells: Implications in carcinogenesis
(BioMed Central, 2008-03-03)
Background: Arsenic is a carcinogen that is known to induce cell transformation and tumor formation. Although studies have been performed to examine the modulation of signaling molecules caused by arsenic exposure, the ...
Prevalence of Escherichia coli O157 in cattle feeds in Midwestern feedlots
(American Society for Microbiology, 2003-09)
Comparisons of enrichment methods (with or without antibiotics and with or without a preenrichment step) using gram-negative (GN) broth or tryptic soy broth (TSB) were conducted with feeds inoculated with Escherichia coli ...
Prevalence and genotypes of Anaplasma species and habitat suitability for ticks in a Mediterranean ecosystem
(American Society for Microbiology, 2008-12)
Anaplasma species are tick-transmitted pathogens that impact veterinary and human health. Sicily is one of the locations where these pathogens are endemic. Sicily represents a typical Mediterranean ecosystem to study ...
New Mycobacterium avium antifolate shows synergistic effect when used in combination with dihydropteroate synthase inhibitors
(American Society for Microbiology, 2005-11)
Mycobacterium avium complex (MAC) is resistant to trimethoprim, an inhibitor of bacterial dihydrofolate reductase (DHFR). A previously identified selective inhibitor of MAC DHFR, SRI-8858, was shown to have synergistic ...
Inseparability inequalities for higher order moments for bipartite systems
(IOP Publishing, 2005-10-07)
There are several examples of bipartite entangled states of continuous variables for which the existing criteria for entanglement using the inequalities involving the second-order moments are insufficient. We derive new ...
Nonclassical correlation of polarization-entangled photons in a biexciton-exciton cascade
(IOP Publishing, 2008-11-07)
We develop a theoretical model to study the intensity–intensity correlation of polarization-entangled photons emitted in a biexciton–exciton cascade. We calculate the degree of correlation and show how polarization ...
Time resolved synthetic aperture terahertz impulse imaging
(AIP Publishing, 2001-12-31)
Using a well characterized terahertz (THz) impulse ranging system we demonstrate broad bandwidth imaging at THz frequencies using an inverse synthetic aperture deconvolution technique. The system demonstrates millimeter ...
dc-field-induced enhancement and inhibition of spontaneous emission in a cavity
(American Physical Society, 2004-08-20)
We demonstrate how spontaneous emission in a cavity can be controlled by the application of a dc field. The method is specially suitable for Rydberg atoms. We present a simple argument based on Stark shifts for the control ...
Factors associated with the presence of coliforms in the feed and water of feedlot cattle
(American Society for Microbiology, 2005-10)
The objective of this study was to investigate coliform counts in feedlot cattle water and feed rations and their associations with management, climate, fecal material, and water Escherichia coli O157 using a cross-sectional ...
Generation of Werner states via collective decay of coherently driven atoms
(American Physical Society, 2006-02-08)
We show deterministic generation of Werner states as a steady state of the collective decay dynamics of a pair of neutral atom coupled to a leaky cavity and strong coherent drive. We also show how the scheme can be extended ...
