Use of fatty acid methyl ester profiles for discrimination of Bacillus cereus T-strain spores grown on different media
(American Society for Microbiology, 2010-03)
The goal of this study was to determine if cellular fatty acid methyl ester (FAME) profiling could be used to distinguish among spore samples from a single species (Bacillus cereus T strain) that were prepared on 10 different ...
Maternal effects of herbivory in Impatiens capensis
(University of Chicago Press, 2010)
Maternal effects of herbivory for fitness-related traits of offspring, especially those traits that are expressed later in a plant's life, have rarely been studied. To better understand how herbivory to the maternal plant ...
Influence of religious affiliation and education on HIV knowledge and HIV-related sexual behaviors among unmarried youth in rural central Mozambique
(Informa UK Limited, 2010-10)
The interactions between religious affiliation, education, HIV knowledge, and HIV-related sexual behaviors among African church youth are poorly understood. In this socio-demographic study, 522 unmarried youth 12-28 years ...
Inhibition of antibiotic-resistant Staphylococcus aureus by the broad-spectrum dihydrofolate reductase inhibitor RAB1
(American Society for Microbiology, 2010-09)
The bacterial burden on human health is quickly outweighing available therapeutics. Our long-term goal is the development of antimicrobials with the potential for broad-spectrum activity. We previously reported phthalazine-based ...
Flare coupled metal parallel-plate waveguides for high resolution terahertz time-domain spectroscopy
(AIP Publishing, 2010-12-03)
We report on a new coupling scheme for high resolution terahertz spectroscopy of microcrystalline films using parallel-plate waveguides. Metal flares are used to couple the terahertz radiation into and out of the waveguide. ...
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 ...
Controlling metamaterial resonances via dielectric and aspect ratio effects
(AIP Publishing, 2010-11-09)
We study ways to enhance the sensitivity and dynamic tuning range of the fundamental inductor-capacitor (LC) resonance in split ring resonators (SRRs) by controlling the aspect ratio of the SRRs and their substrate thickness. ...
Population- and genome-specific patterns of linkage disequilibrium and SNP variation in spring and winter wheat (Triticum aestivum L.)
(BioMed Central, 2010-12-29)
Background: Single nucleotide polymorphisms (SNPs) are ideally suited for the construction of high-resolution genetic maps, studying population evolutionary history and performing genome-wide association mapping experiments. ...
Proboscis conditioning experiments with honeybees, Apis mellifera caucasica, with butyric acid and DEET mixture as conditioned and unconditioned stimuli
(Oxford University Press, 2010)
Three experiments are described investigating whether olfactory repellents DEET and butyric acid can support the classical conditioning of proboscis extension in the honeybee, Apis mellifera caucasica (Hymenoptera: Apidae). ...
Subolesin expression in response to pathogen infection in ticks
(BioMed Central, 2010-02-19)
Background: Ticks (Acari: Ixodidae) are vectors of pathogens worldwide that cause diseases in humans and animals. Ticks and pathogens have co-evolved molecular mechanisms that contribute to their mutual development and ...
