Abstract: Methods and systems for measuring and using the oxidation-reduction characteristics of a biological sample are provided. The system generally includes a test strip and a readout device. A fluid sample is placed in the test strip, and the test strip is in turn operatively connected to the readout device. The readout device provides a controlled current that is sent across the fluid in the sample chamber. In addition, the readout device identifies an inflection point or transition time at which the voltage between contacts of the test strip is changing at the highest rate. The oxidation-reduction capacity of the sample is taken as the integral of the current profile from the time at which current begins to be supplied to the sample to the identified transition time.

Abstract: The invention discloses diagnostic techniques based on single cell genomics, consisting of obtaining a blood sample, enriching a sub-population of cells present in the blood sample, sequestering individual cells or group of cells from the blood sample, obtaining sequencing data from the sequestered cells or group of cells, using genetic variant information to determine the provenance of the cells, and genetically analyzing the cells of the correct provenance to provide a diagnostic readout. Using the cell-based testing techniques of the invention, the number of false positives is greatly reduced when compared to cell-free DNA (cfDNA) based traditional testing techniques. The invention may be effectively employed for non-invasive prenatal (NIPT) diagnostics, oncological testing and other diagnostic procedures.

Abstract: A method for controlling infections in a facility such as a hospital or foodservice establishment is provided. The method comprises tagging assets, monitoring asset location and pathogen contamination for each asset over time, analyzing data sets to identify which assets are the critical control points for pathogen transfer, and coating a residual self-sanitizing coating composition on each asset identified as a critical control point. The infection control method shuts down pathogen transfer routes by mitigating or eliminating pathogen growth on the critical control points.
Abstract: An apparatus is provided for controlling hospital acquired infections by targeting critical control points for pathogen transfer. An infection control apparatus comprises an asset tagging unit; a spraying unit; a power supply unit; optionally a DNA/RNA sequencing unit; and a computing unit comprising a non-transitory computer-readable medium encoded with program instructions for controlling the asset tagging unit and the spraying unit to perform a method of infection control in the facility. In general, the apparatus is used to identify which assets are critical control points for pathogen transfer and to treat those assets with a residual self-sanitizing coating.
Abstract: The invention provides a method for determining whether a human immunodeficiency virus is likely to be have enhanced ability to enter a cell expressing CD4 and CXCR4 relative to a reference HIV. In certain aspects, the methods comprise detecting one or more amino acids in an envelope protein of the HIV associated with enhanced ability to enter CD4- and CXCR4-expressing cells and determining that the HIV's ability to enter such cells is enhanced relative to a reference HIV, e.g., an HIV that does not comprise such amino acid(s).
