Abstract: Systems and methods of assessing significance of metabolites in diseases are provided. A multi-omics downstream analysis pipeline can represent lung microbiome ecology as a heterogeneous network of microbes and metabolites. Such an analysis can demonstrate the significance of a particular metabolite in the microbiome of a patient (e.g., a human patient).

Abstract: A method of determining the presence of Pseudomonas involves establishing a gaseous headspace over a surface suspected of containing at least one Pseudomonas strain and contacting at least a portion of the gaseous headspace with a capillary microextraction of volatiles (CMV) sampling device to absorb at least one component of the headspace by the CMV sampling device. The component loaded CMV sampling device is coupled to an injection port of an analytical device where the components are desorbed into the analytical device, where components are separated, detected, and identified to determine if one or more of the identified components is a biomarker for at least one Pseudomonas strain.

Abstract: Compounds of Formula (I) are disclosed herein and their use in inhibiting quorum sensing in bacteria.

Abstract: A method and system for detecting a DNA strand using carbon nanotubes or nanowires. A specific single strand of template DNA serves as a probe for its complementary strand in a solution containing DNA segments to be tested. The single-stranded sequence-specific DNA probe segment, whose ends are modified with amine, is attached between two carbon nanotubes/nanowires. When complementary strands representing DNA segments under test are brought near the probe strands, a dielectrophoresis (DEP) field may enhance the probability of selective hybridization between the complimentary target DNA and probe DNA. A change in electrical conductance in the probe strand occurs upon hybridization of the complementary target DNA with the single probe strand. This conductance change may be measured using the two carbon nanotubes or nano-dimensional electrodes. By exploiting nano-dimensional electrodes and single strand probe DNA, the proposed system is capable of accurately detecting a single molecule of DNA.
