Hydrogen sulfide, bacteria, and fish: a unique, subterranean food chain
(Ecological Society of America, 2011)
Photoautotrophs are generally considered to be the base of food webs, and habitats that lack light, such as caves, frequently rely on surface-derived carbon. Here we show, based on analysis of gut contents and stable isotope ...
Transrectal ultrasound-integrated spectral optical tomography of hypoxic progression of a regressing tumor in a canine prostate
(SAGE Publications, 2011-12-01)
The objective of this study was to evaluate if transrectal optical tomography implemented at three wavelength bands for spectral detection could monitor changes of the hemoglobin oxygen saturation (SₜO₂) in addition to ...
Terahertz two-cylinder waveguide coupler for transverse-magnetic and transverse-electric mode operation
(AIP Publishing, 2011-02-18)
We report the coupling and guiding of broadband terahertz radiation using a two-cylinder waveguide coupler. For the transverse electromagnetic TEM (TM0) geometry, the two opposing metal cylinders exhibit an amplitude ...
Genetic modification of alternative respiration in Nicotiana benthamiana affects basal and salicylic acid-induced resistance to potato virus X
(BioMed Central, 2011-02-28)
Background: Salicylic acid (SA) regulates multiple anti-viral mechanisms, including mechanism(s) that may be negatively regulated by the mitochondrial enzyme, alternative oxidase (AOX), the sole component of the alternative ...
In vitro efficacy of antibiotics commonly used to treat human plague against intracellular Yersinia pestis
(American Society for Microbiology, 2011-08)
Yersinia pestis initiates infection as a facultative intracellular parasite in host macrophages; however, little is known about the efficacy of antibiotics commonly used to treat human plague against intracellular Y. pestis. ...
