Design of Switch-Mode Amplifier to Transform Single Transmit Hardware for Multi-Nuclear MRI

This technology includes the design and implementation for 1H-nuclear magnetic resonance imaging (MRI) that allows single transmit hardware to be "transformed" for another nucleus excitation to perform multi-nuclear MR. A radiofrequency (RF) optically controlled switch-mode amplifier prototype is tuned for excitation of two nuclei. The amplifier received the nuclei carrier signals optically through a single fiber.

Longer-lived Mouse Models for Studying Gaucher Disease

The invention is a novel longer-lived mouse model for Gaucher disease. Gaucher disease is a genetic disorder that results from deficiencies in the enzyme glucocerebrosidase (GBA). The use of animal models to study how the disease progresses has been invaluable in research of this disorder. However, existing mouse models have been limited due to early mortality because the GBA enzyme plays an important role in lysosomal storage.

Human Salivary Gland Cell Lines for Propagation of Enteric Viruses

Enteric viruses like norovirus, rotavirus and astrovirus mainly transmit through fecal-oral route by ingestion of contaminated food and water and productively replicate in the intestines. Recently, researchers at National Heart, Lung, and Blood Institute (NHLBI) and National Institute of Dental and Craniofacial Research (NIDCR) identified a second route of enteric viral transmission by demonstrating that these viruses also productively and persistently infect salivary glands, reaching titers comparable to that in intestines.

Cyclopentane-modified FIT-PNAs as Highly Emissive and Selective RNA/DNA Sensors for Use in Clinical Diagnostics

This technology includes Cyclopentane-modified Peptide Nucleic Acids (cp-PNAs) which can be combined with (forced-intercalation) FIT-PNAs to create highly sensitive probes that detect the presence of complementary RNA sequences. We have studied the beneficial effects of incorporating cyclopentane groups into the backbone of PNAs, which leads to proper preorganization of the PNA backbone into the conformations needed to bind complementary RNA sequences. The cp-PNAs typically have improved thermodynamic stability for binding to complementary nucleic acids compared to unmodified PNAs.

microRNAs for the Improvement of Functional Protein Expression from HEK Cells

This technology includes five microRNA mimics which were identified to improve the functional expression of hard-to-express membrane protein. These miRNAs are: hsa-miR-22-5p; hsa-miR-18a-5p, hsa-miR-22-3p, hsa-miR-429 and hsa-miR-2110. Improving expression level of recombinant mammalian proteins is vital, as the adequate supply of correctly folded proteins is the prerequisite for all structure and function studies.

Luciferase Immunoprecipitation System (LIPS) for Point-of-care Diagnosis of COVID-19 Antibodies

This technology includes a sensitive and specific method to rapidly detect antibodies in biofluids. This assay has been used for the detection of antibodies in blood, urine, and saliva. Until now, no one has used LIPS to detect clinically relevant antibodies to SARS-CoV-2 Nucleocapsid (N) or Spike (S) in saliva. Briefly, LIPS employs recombinantly synthesized target proteins or peptides (e.g., S and N proteins) tagged with light-emitting proteins as targets to be captured by host produced immunoglobulins. These immunoglobulins can be captured by protein A/G beads and immobilized.

MicroRNAs for Cell Line Utilization and Future Therapeutic Application

This technology includes microRNAs for use in cell lines for protein production and potentially future treatments of cancer or diseases related to metabolism. Mmu-miR-466h was identified as a major apoptotic regulator in suspension adapted Chinese Hamster Ovary cells. Mmu-miR-466h was found to have the pro-apoptotic activity by targeting some anti-apoptotic genes for degradation during the exposure of CHO-S cells to the nutrients depleted media.

Nucleoside Agonists of Adenosine Receptors as Cardio- and Cerebroprotective Agents

This technology includes a compound for use as a selective agonist of the A1 adenosine receptor (AR) for therapeutic hypothermia and other conditions. We have examined various synthesized nucleosides in a model of mouse hypothermia, in conjunction with AR knockout mice, to characterize the biological profiles. In trying to identify novel highly selective A1AR agonists that have superior in vivo activities, we have adapted a means of rigidifying the ribose moiety of adenosine in the form of a bicyclic (N)-methanocarba ring.

Ionophores as Treatment for Sickle Cell Disease

This technology includes a method using ionophores to reduce sickling in patients with sickle cell disease. Sickle cell disease is caused by polymerization of a hemoglobin mutant, and the only approved treatment acts by replacing sickle hemoglobin with fetal hemoglobin, thereby increasing the delay time prior to polymerization. This drug is only partially successful because it does not induce fetal hemoglobin synthesis in all cells.

Synthetic Biotin-streptavidin Replacement for Use in the Development of Clinical Diagnostics

This technology includes an alternative synthetic biotin-streptavidin replacement system for use in the development of clinical diagnostics. Peptide nucleic acids (PNA) when functionalized onto the surface of microspheres are capable of targeting short RNA targets from solutions. However, when the target nucleic acid becomes longer and complicated in structure, the PNA no longer efficiently binds due to steric hindrance from the microspheres and/or slow hybridization kinetics of larger nucleic acid targets.
