A Preclinical Orthotopic Model for Glioblastoma Multiforme that Represents Key Pathways Aberrant in Human Brain Cancer

Current therapies for glioblastoma multiforme (GBM), the highest grade malignant brain tumor, are mostly ineffective, and better preclinical model systems are needed to increase the successful translation of drug discovery efforts into the clinic. Scientists at the National Cancer Institute (NCI) have developed and characterized an orthotopic genetically engineered mouse (GEM)-derived model of GBM that closely recapitulates various human GBM subtypes and is useful for preclinical evaluation of candidate therapeutics.

Human Monoclonal Antibodies That Target the RH5 Complex of Blood-Stage Plasmodium Falciparum

249 million people were afflicted with malaria in 2022. There are five Plasmodium parasite species that cause malaria in humans. Of the five, Plasmodium falciparum causes most of the incidence of human disease. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. The pathogenesis of malaria is associated with blood-stage infection and antibodies specific to the parasite blood-stage antigens may be able to control parasitemia.

General-purpose Deep Learning Image Denoising Based on Magnetic Resonance Imaging Physics

This technology includes a novel method to train deep learning convolution neural network model to improve the signal-noise-ratio for the magnetic resonance (MR) imaging. The novelty lies on the fact that actual MR imaging physics information is used in the deep learning training. The resulting model achieves significant signal-to-noise ratio (SNR) improved for different acceleration factors in MR imaging. The resulting model can be used for many body anatomies (e.g., brain, heart, liver, spine, etc.) to significantly improve the SNR.

Encapsulation of Fluorescent Nanodiamonds into Poly-dopamine (PDA) Shell and Further Covalent Functionalization of the PDA Shell for Diagnostic Imaging Applications

This technology includes a new class of nanoparticles in the carbon family, fluorescent nanodiamonds (FNDs), exhibiting superb physical and chemical properties for diagnostic imaging applications. We have developed a simple, fast, and robust method to encapsulate FNDs in polydopamine that can be further functionalized. By integrating anatomical and molecular based imaging capabilities, multimodal nanoparticle probes are becoming important in the paradigm shift from conventional to future imaging technologies.

Engineered Human Induced Pluripotent Stell Cell (iPSC) Lines for Multiple Therapeutic and Diagnostic Uses

This technology includes ten engineered human induced pluripotent stem cell (iPSC) lines with reported genes inserted into safe harbor sites for use in therapy and diagnostic screening assay development as well as basic stem cell biology research. These cell lines have the potential to differentiate into all cells in the body, and theoretically can proliferate/self-renew indefinitely.

A Rapid Method for Producing Antibodies

Antibodies are specialized proteins produced by the immune system which target and neutralize foreign materials, such as viruses or bacteria. Antibodies have a variety of useful applications in diagnostics, therapeutics, and as research reagents. Despite their widespread use there is no standard method to produce antibodies, and currently available methods are labor and time intensive.

Novel System for HIV-1 Vaccine Development

The available technologies describe specific immunogenic peptides, peptide modifications and methods for identifying additional immunogens against HIV-1 surface proteins, gp120 and gp41. Additionally, detailed methods for use of the described immunogenic peptides in the development of vaccines and diagnostics for HIV-1 are disclosed. The current technologies further include a comprehensive system for immunogen design, comprising in silico design coupled to feedback from X-ray crystallography, antigenic analysis, and immunization.

Device and Method for Protecting Against Coronary Artery Compression During Transcatheter Mitral Valve Annuloplasty

Catheter-based mitral valve regurgitation treatments that use a coronary sinus trajectory or coronary sinus implant can have unwanted effects because the coronary sinus and its branches have been found to cross the outer diameter of major coronary arteries in a majority of humans. As a result, pressure applied by any prosthetic device in the coronary sinus (such as tension on the annuloplasty device) can compress the underlying coronary artery and induce myocardial ischemia or infarction.

Inhibition of HIV Infection through Chemoprophylaxis Using Emtricitabine and Tenofovir

The invention is directed to prophylactic administration of emtricitabine (FTC) in combination with tenofovir or its prodrug, tenofovir disoproxil fumarate (TDF), to protect against transmission of human immunodeficiency virus (HIV) infection. Also disclosed are other nucleoside reverse transcriptase inhibitors (NRTIs) and nucleotide reverse transcriptase inhibitors (NtRTIs) that, when administered in combination, protect against HIV infection.

Intralipid as a Contrast Agent to Enhance Subsurface Blood Flow Imaging

This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.
