Resolution Enhancement for Light Sheet Microscopy Systems

The invention pertains to a technique for enhancing the resolution of images in light sheet microscopy by adding additional enhanced depth-of-focus optical arrangements and high numerical aperture objective lenses. The technique employs an arrangement of three objective lenses and a processor for combining captured images. The image composition utilizes the greater resolving power of the third high numerical aperture objective lens by imaging the light sheet and enhanced depth-of-focus arrangement resulting in improved overall resolution of the light sheet system.

High-Titer, Fast-Growth Chimeric Dengue/West Nile Viruses for Vaccine and Diagnostics Development

Mosquito-transmitted dengue virus is one of the leading causes of illness in the tropics and subtropics. There is currently no vaccine available and a number of DENV diagnostic and research applications depend on the production of large amounts of these viruses. However, due to the slow growing nature of DENVs these protocols are very time-consuming.

Heterocyclic Compounds for the Treatment of Hepatitis C Virus

The vast majority of people infected with Hepatitis C Virus (HCV) will have chronic infection. Over decades, this can lead to liver disease and liver cancer. In fact, HCV infection is the leading cause of liver transplants in the U.S. Several new drugs have recently come into the market that have changed the HCV treatment paradigm. However, the effectiveness of these new drugs can vary depending on the HCV genotype. Furthermore, all oral, interferon free therapeutic regimens for HCV infection will need combinations of drugs that target different aspects of the HCV life cycle.

Novel Method and Kit Using Monoclonal Antibodies for More Sensitive Detection of Dengue Virus

Following primary dengue virus (DENV) infection, non-structural protein 1 (NS1), a dengue-specific glycoprotein, is present in blood and is easily detected by various assays. However, for any infection thereafter (secondary infection), bioavailability of the glycoprotein greatly reduces sensitivity of DENV detection. Since secondary DENV infection is a risk factor for developing hemorrhagic fever, there is increasing need for more sensitive detection at this stage.

Ultra-sensitive Diagnostic Detects fg/mL-pg/mL Pathogen/Disease Protein by Visual Color Change

This technology is an ultra-sensitive colorimetric assay, based on an enzyme-catalyzed gold nanoparticle growth process, for detection of disease-associated proteins (biomarkers) and disease diagnosis. Current detection methods, such as ELISA immunoassays, measure concentrations above 0.1 ng/mL in a sample. PCR, although more sensitive than ELISA, requires expensive and specialized equipment and reagents, skilled labor, and complex analysis techniques. This assay detects fg/mL to pg/mL concentrations, allowing detection and diagnosis in the earliest stage of disease or infection.

LRRK2 Inhibitors: Novel Treatment for Intestinal Bowel Disorders

Use of Leucine Rich Repeat Kinase 2 (LRRK2) inhibitors for the treatment of Intestinal Bowel Disorders (IBD) is disclosed. IBD is a broad term that describes conditions with chronic or recurring immune response and inflammation of the gastrointestinal tract. Crohn's disease and ulcerative colitis, two common forms of idiopathic IBD, are chronic, relapsing inflammatory disorders of the gastrointestinal tract.

Highly Sensitive Tethered-Bead Immune Sandwich Assay

This technology is a highly sensitive tethered-bead immune sandwich assay. Analyte molecules are captured between two antibodies, a capture antibody and a detection antibody. The capture antibody on a micron-size bead binds analyte from a sample fluid. The bead-captured analyte is then exposed to a “detection” antibody that binds to the bead-captured analyte, forming a “sandwich”. The sandwiched analyte-bead complex then connects to a flexible polymer (such as DNA) anchored on a solid surface to form tethered particles.

CXCR4 Reduction Leads to Enhancement of Engraftment of Hematopoietic Stem Cells

Methods of enhancing engraftment of donor hematopoietic stem cells (HSCs) by reducing expression or activity of CXCR4 in HSCs is described. HSC are the only cells in the bone marrow that are both pluripotent and long lived. Bone marrow transplantation (BMT) using HSC is an increasingly common medical therapy for severe hematologic cancers and primary hematologic immunodeficiencies. However, for significant HSC engraftment to occur there must usually be pre-transplant conditioning with either irradiation or chemotherapy or both.

T Cell-Based Adoptive Transfer Immunotherapy for Polyomavirus-Associated Pathologies

Available for licensing are methods to generate T cells responsive to multiple polyomaviruses. The resulting T cell populations could be useful in treating immunosuppressed individuals with polyomavirus infections or polyomavirus-associated pathologies such as Merkel cell carcinoma (MCC), polyomavirus-associated nephropathy (PVAN), hemorrhagic cystitis, progressive multifocal leukoencephalopathy (PML), and trichodysplasia spinulosa (TS). The methods could also be used to restore polyomavirus-specific immunity in immunocompromised individuals.
