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.

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.

Compatible 3-D Intracardiac Echography Catheter and System for Interventional Cardiac Procedures

This technology includes a versatile intravascular 3D intracardiac echocardiography (ICE) catheter that can operate under conventional X-ray and MRI for use during interventional cardiac procedures. The 3D MRICE and custom, GPU-based, real-time imaging system are also included. Structural heart disease affects more than 2.9% of the US population, and common interventional procedures can be difficult because of limitations in catheter devices and inadequate image guidance.

Vitamin C renal leak as a clinical diagnostic tool in the detection, monitoring, and management of acute and chronic diseases

This technology includes a clinical diagnostic tool for measuring vitamin C elimination by human kidneys that can be used for detecting, monitoring, and managing acute and chronic diseases. Findings revealed significant associations between vitamin C renal leak status and clinical variables affecting renal function and blood glucose. The technology uses vitamin C depletion-repletion kinetics and pharmacokinetic models to establish a physiological vitamin C renal threshold.

Locally Delivered Alkaline Phosphatase for Treatment of Periodontal Disease

This technology includes a product for local delivery of alkaline phosphatase for the treatment of periodontal disease. Our laboratory has discovered that factors regulating phosphate metabolism and specifically the appropriate balance between phosphate (Pi) and pyrophosphate (PPi) at local sites are needed for formation (development), maintenance and regeneration of the tooth root surface (cementum), periodontal ligament (PDL) and surrounding alveolar bone, i.e., the periodontal apparatus.

A Novel Rapid Point-of Care Diagnostic Method for Infectious and Autoimmune Diseases

Rapid point-of-care, antibody-based testing is not available for the diagnosis of autoimmune and most infectious diseases. For detecting autoantibodies associated with most autoimmune conditions, fluid-phase immunoprecipitation assays are required. However, these assays usually involve radioactivity and are not feasible for point-of-care applications. The subject invention describes methods of using neodymium magnet for diagnosis of infectious and autoimmune diseases including lupus, Sjögren's syndrome, type I diabetes, HIV and Lyme disease.

Apparatus for Cryogenic-Electron Microscopy Sample Preparation

Cryo-Electron Microscopy (cryo-EM) is used to obtain high-resolution structural images of macromolecular structures. Samples must be purified and loaded onto cryo-EM grids before imaging. The ideal cryo-EM grid consists of particles that are evenly and richly distributed in a broad distribution of orientations throughout the holes of the support film. Current techniques to prepare cryo-EM grids are performed manually and require trial and error, resulting in a bottleneck in cryo-EM workflows.

Polarimetric Accessory for Colposcope

In medical diagnostic procedures for examining the cervix and the tissues of the vagina and vulva, long working-distance (-30 cm) lighted binocular microscopes (colposcope) that provide up to 25x optical magnification are used to create an illuminated magnified view. Speculum dilations can give rise to specular reflections from the tissue surface, causing physicians to overlook possible abnormalities – thus decreasing the quality of a colposcopy. 

A Specialized Tissue Collection Device for the Preservation and Transportation of Needle Biopsies

The ability to hold and transport tissue, especially needle biopsies in a pre-defined and controlled environment is critical for the preservation of biopsy samples in downstream analytic applications. Currently, tissue specimens are placed in open containers with variable, poorly controlled solutions applied to them, often in less than sterile conditions.  Evaluation of the tissue by examination through a stereoscope or similar approaches to determine adequacy is limited and requires manipulation of the tissue that can further damage the tissue.

AngleNav: Micro-Electro-Mechanical Systems (MEMs) Trackers to Facilitate Computed Topography (CT)-Guided Needle Puncture

Conventional free-hand needle puncture procedures for biopsy and other procedures, often rely on unguided manual movements to guide a needle to its destination. Freehand procedures risk missing the tumor, or accidental injury, such as puncturing a vital organ. Needle guidance systems may improve accuracy and reduce risks but available guidance technologies are cumbersome and expensive and may carry other risks.
