Design and Biological Activity of Novel Stealth Polymeric Lipid Nanoparticles for Enhanced Delivery of Hydrophobic Photodynamic Therapy Drugs

Nanoparticles such as lipid-based nanoparticles (LNPs) represent a relatively new era of targeted drug delivery systems wherein these biocompatible particles can carry the drug(s) of interest to a specific tumor site. The new generation of nanoparticles, known as stealth nanoparticles, are engineered to have a coating of polyethylene glycol polymer (PEG) or other glycolipids that enable them to evade the immune system and have a longer circulation lifespan as well as improved bioavailability to diseased tissue and reduced non-specific toxicity.
 

Real-time PCR Detection of <em>Streptococcus pneumoniae</em> with High Sensitivity and Specificity

Streptococcus pneumoniae is the leading cause of community-acquired pneumonia and is also a frequent cause of bloodstream, brain and spinal cord, ear, and sinus infections. According to 2015 CDC data, an estimated 900,000 Americans get pneumococcal pneumonia each year and approximately 5-7% die from it annually. Accurate diagnosis and early treatment are important for improving patient outcomes.

Immunoassay for the Simultaneous Detection of Functional Antibodies against Multiple Serotypes of <em>Streptococcus pneumoniae</em> and Other Bacteria Types

Streptococcus pneumoniae, or pneumococcus, is a type of bacteria that causes pneumococcal disease. Pneumococcal infections can range from ear and sinus infections to pneumonia and bloodstream infections. Children younger than 2 years old and adults 65 years or older are among those most at risk for disease.

Monoclonal Antibodies for Detection of Rabies Virus Antigen and Confirmatory Rabies Diagnosis

According to the World Health Organization (WHO), rabies causes greater than 59,000 deaths every year in over 150 countries as of 2017. A rapid and reliable diagnostic test for rabies is critical for prophylaxis considerations in humans bitten by animals as well as for basic surveillance and animal rabies control programs. The World Organization of Animal Health (OIE) and WHO Expert Committee on Rabies recently approved the direct rapid immunohistochemical test (DRIT) for rabies diagnostics.

High-Resolution and Artifact-Free Measurement and Visualization of Tissue Strain by Processing MRI Using a Deep Learning Approach

This technology includes a system for automatic artifact-free measurement and visualization of tissue strain by MRI at native resolution. The investigation of regional soft tissue mechanical strain can serve as a unique indicator for different related disorders. For example, measurement of myocardial tissue during contraction can help calculate, track, and assess cardiac stress. Currently, methods such as tagging MRI (tMRI) are used for imaging soft tissue deformation. Despite being well validated, methods such as tMRI suffer from low spatial and temporal resolution.

A Device to Measure Force Continuously During Handgrip Contraction and Relaxation for Myotonic Dystrophies

This invention relates to two devices that reliably, sensitively, and accurately measures force during handgrip contraction and subsequent relaxation. A delayed relaxation after a sustained and forceful handgrip is a cardinal symptom of myotonic dystrophies (DM). This delayed relaxation, handgrip myotonia, may be a therapeutic response biomarker in clinical trials.

Reducing Bloodstream Neutrophils as a Treatment for Lung Infection and Inflammation

During lung infection, bloodstream neutrophils (PMNs) responding to infection travel to the airspace lumen. Although successful arrival of microbicidal PMNs to the airspace is essential for host defense against inhaled pathogens, excessive accumulation of PMNs in the lung contributes to the pathogenesis of several prevalent lung disorders, including acute lung injury, bronchiectasis, and COPD. Unfortunately, there is no treatment for controlling PMN accumulation in the lung.

Improved Cell Survival and Differentiation of Human Pluripotent Stem Cells by Combining Small Molecules Chroman-1 and Emricasan

This technology includes the use of the combination of the compounds Chroman-1 and Emricasan to achieve virtually 100% cell survival during human pluripotent stem cell passaging, cryopreservation/thawing, and differentiation in 2D and 3D cultures. Human pluripotent stem cells, including ESCs and iPSCs, are highly sensitive cells and undergo apoptosis during these routine procedures. A screening approach was used to identify the combination of the two compounds in this invention.

A Highly Efficient Differentiation Protocol for Placental Cells Derived from Human Pluripotent Stem Cells

This technology includes a robust and highly efficient protocol that differentiates human pluripotent stem cells (hPSCs) into the developmental precursor of placental cells, the trophectoderm (TE), under chemically defined conditions. The in vitro generation of TE cells holds great promise for modeling diseases of the placenta, drug screening, and cell-based therapies.

Small Molecule Inhibitors of the Ferroptosis Programmed Cell Death Pathway

This technology includes the identification and use of small molecules to rescue cells undergoing ferroptosis, a type of programmed cell death. These small molecules can be used as treatments in situations where epithelial cells are being damaged, including respiratory disorders, brain injury (including traumatic brain injury), renal injury, radiation-induced injury, and neurodegenerative disorders. Ferroptosis is a type of programmed cell death that is triggered by an increased presence of oxidants.
