Viruses, including corona viruses such as COVID-19, are often present in the mouth or nose of a person before they infect the body. The disclosed electrochemical device destroys or denatures viruses in the mouth or nose rendering the viruses ineffective to cause infection by applying a low voltage potential to the mucus. The device has a potentiostat powered by a small battery embedded in a plastic frame that fits in a person's mouth. The device has electrodes to contact the mucus of the mouth or nose. The mucus serves as electrolyte, conducting ions as well as viruses with their protein “skin” towards the electrode. The viruses are adsorbed onto the metal probes where the electrical current denatures the protein skin of the virus rendering the virus ineffective to cause infection.

The present disclosure provides methods and compositions for determining whether a patient exhibiting acute gastroenteritis will benefit from treatment with therapeutic agents that inhibit Norovirus genogroup I (GI) or Norovirus genogroup II (GII). The methods disclosed herein are based on detecting Norovirus genogroup I (GI) and Norovirus genogroup II (GII) in a stool sample without extracting viral nucleic acids from a clinical specimen prior to performing real-time reverse transcription PCR. Kits for use in practicing the methods are also provided.

Methods, devices, systems, and kits for use in detecting and measuring infectious diseases are provided. In particular embodiments, methods, devices, systems, and kits for detecting and measuring Ebola virus, including Ebola Zaire strain virus, are provided. Devices and systems may be used within regions suffering from Ebola or other infections, providing local, rapid, and effective diagnosis of infectious diseases such as Ebola, improving treatment and reducing or preventing spread of such infectious diseases.

Diagnostic devices test markers for viral infection and markers for bacterial infection to effectively assist in the rapid differentiation of viral and bacterial infections, to differentiate between colonization and active infection, and to better diagnose microbiologically unconfirmed patients. In other embodiments, detecting a presence of MxA in combination with either the bacterial biomarker C-reactive protein or the bacterial biomarker procalcitonin increases the specificity of the bacterial biomarker with a concurrent improvement in sensitivity.

Test devices are provided for determining the presence of a first ligand in a sample. In some embodiments depletion conjugates are used to deplete the ligands different from but related to the first ligands from the sample.

A system for providing immunoassay test results for multiple medical conditions, comprising a testing device having thereon an alignment target and having a plurality of immunoassay test strips, the plurality of immunoassay test strips each including a sample pad capable of receiving a biologic sample, a conjugate pad containing particles for conjugating with antibodies or antigens present in the biologic sample, and a membrane strip having a test line and a control line, wherein the test line and the control line are viewable, and a mobile device having a camera, a viewing screen, and a software application stored thereon, wherein the software application provides executable instructions to capture an image of the testing device, process an image to determine pixel count and line intensity of the test line of each of the plurality of immunoassay test strips, and present test results on the viewing screen.

Chimeric proteins that comprise one or more amino acid sequences of an insect-specific flavivirus and one or more other immunogenic proteins are provided. The chimeric proteins are suitably capable of forming virus particles. The chimeric protein and/or virus particle may be suitable for delivery to a subject to elicit an immune response to a pathogen and/or for diagnosis or detection of a pathogen. Also provided are nucleic acids and vectors encoding the chimeric proteins, and isolated chimeric insect-specific flaviviruses comprising the chimeric proteins and/or nucleic acids.

Provided herein are, inter alia, antibodies, antigen-binding antibody fragments, cells, polynucleotides, compositions, kits, and methods relating to the detection of HBV protein X (HBx), e.g., in vitro and in vivo. Included are antibodies and fragments thereof that bind HBx, as well as kits, cells, and compositions comprising such antibodies and fragments.

The invention relates to polynucleotide agents targeting programmed cell death 1 ligand 1 (PD-L1) gene, and methods of using such polynucleotide agents to inhibit expression of PD-L1 and to treat subjects having a PD-L1-associated disorder.

A fabric top for a convertible vehicle includes, in sequence: an outer cover layer, an insulating layer, an absorber layer and an inner cover layer. The absorber layer at 500 hz has an absorption coefficient of 10 to 65%, at 1000 hz has an absorption coefficient of 15 to 110%, at 2000 hz has an absorption coefficient of 33 to 115%, at 4000 hz has an absorption coefficient of 60 to 110% at 8000 hz has an absorption coefficient of 85 to 120%.
