Abstract: The invention provides the use of a formulation containing cyclodextrine, quercetin and zinc at appropriate concentrations to mitigate infections by enveloped viruses, such as COVID-19 virus (SARS-CoV-2), influenza and HIV. While the different forms of cyclodextrin prevent the entry of coated viruses into host cells by extracting and sequestering cholesterol molecules at the virus envelope and at the host cell plasma membrane, the natural plant-based ionophore quercetin in the formulation enables cellular entry of zinc, inhibiting viral replication by altering polymerase activity in the host cell. SUBSTANCE: This formulation is adapted for both surface use and introduction to a subject by dispersal, utilizing the known methods of measured nasal sprays or inhalers, wet wipes and medicated masks. The formulation is introduced in the form of an aqueous phosphate buffered saline pH 7.5 solution, containing 0.

Abstract: The invention provides a method for preparing an expanded renal (kidney) tissue sample suitable for microscopic analysis. Expanding the kidney sample can be achieved by binding, e.g., anchoring, key biomolecules to a polymer network and swelling, or expanding, the polymer network, thereby moving the biomolecules apart as further described herein. As the biomolecules are anchored to the polymer network, isotropic expansion of the polymer network retains the spatial orientation of the biomolecules resulting in an expanded, or enlarged, kidney sample.

Abstract: A method for diagnosing cancer in an expanded biological tissue sample of a patient comprising providing at least one sample image of the expanded biological tissue sample; providing a computer configured to analyze the sample; analyzing, with the computer, the sample detect and segment nuclei; calculating, with the computer, molecular characteristics of those nuclei; and determining, with the computer, a diagnosis of cancer of the sample by comparing the sample with a benign normal tissue reference.

Abstract: The invention provides a method for preparing an expanded biological specimen suitable for microscopic analysis. Expanding the biological sample can be achieved by binding, e.g., anchoring, key biomolecules to a polymer network and swelling, or expanding, the polymer network, thereby moving the biomolecules apart as further described below. As the biomolecules are anchored to the polymer network isotropic expansion of the polymer network retains the spatial orientation of the biomolecules resulting in an expanded, or enlarged, biological specimen.
