Diagnostics Management Team

The sheer volume of medical information available to physicians today is overwhelming. Diagnostic Management Team provides a concise, accurate method for ordering the correct diagnostic tests every time, and it returns the results in a uniform report format, easily read by the physician. This has already been launched within Vanderbilt University, with a high adoption rate amongst physicians and has already shown significant savings.

'Coffee Ring' Diagnostic for Point-of-Care Biomarker Detection

Bright minds at Vanderbilt University have unveiled a breakthrough technology that could bring sophisticated biomarker diagnostics to the developing world. The point-of-care diagnostic is designed to be used in the field; no specialized equipment, expertise, or white lab coats are required. The diagnostic is based upon the ingenous observation that evaporating liquid droplets leave behind a characteristic ring pattern, which may be familiar to our readers in the form of a coffee-ring stain.

Porous Silicon Membrane Waveguide Biosensor

Vanderbilt researchers have developed a low-cost, high sensitivity sensor based on a porous silicon (PSi) membrane waveguide. This sensor is designed to be a cost-effective alternative to conventional fiber optic and SPR sensors for both biosensing and chemical sensing applications.

Simultaneous RNA and Gene Expression Profiling Using Mass Spectrometry

This technology allows the simultaneous detection of RNA transcript abundance (as an assay of gene expression) and protein abundance (as an assay of protein expression) from biological samples without RNA isolation, labeling or amplification. Existing technologies allow for very efficient determinations of protein abundance from a wide variety of biological samples. These methods are in widespread use and are based on mass spectrometry technologies. There are no available technologies that allow efficient and quantitative assessment of multiple RNA transcripts without a previous isolation followed by labeling and/or amplification. The most efficient technologies currently available make use of DNA microarrays to profile RNA abundance as a measure of gene expression. While very robust and useful, these technologies are very labor intensive and suffer from a number of technological drawbacks. This technology takes advantage of a number of existing methods and techniques and brings them together in a novel manner that greatly expands the state of the art for gene expression.

Filament Based Point-of-Care Platform

Vanderbilt engineers have developed a robust platform for point-of-care (POC) diagnostics applicable to infectious diseases, biowarfare agents and environmental and agricultural testing. This technology uses capture antibodies on a polyester filament, or DNA, on a gold wire that act as molecular hooks to troll for viral or bacterial protein antigens, RNA or capture DNA present in a small biological sample solution. It is envisioned that once the analytical POC device is purchased, a different single-use filament would be sold for each pathogen test of interest.

System and Method for Measuring of Lung Vascular Injury by Ultrasonic Velocity and Blood Impedance

The present invention is a method for assessing capillary permeability to determine vascular lung injury without requiring the injection of radioactive material or requiring the sampling of blood. The method includes measuring impedance and ultrasonic velocity of blood flow through a lung. A hypertonic bolus is injected into the blood flow, and measurements of the blood flow are taken to determine the ultrasonic velocity and the electrical impedance of the blood. These measurements are used to calculate the capillary transport quantity, which is the product of the reflection coefficient for movement of fluid across the capillary barrier and the filtration coefficient. The measured value of the capillary transport quantity can then be compared to a conventional capillary transport quantity for healthy lungs, and one can determine injury by a significant decrease in the measured capillary transport quantity as compared to the standard measurements. Furthermore, a comparison of the osmotic transient graphs of the plotted indicator curves can serve to acknowledge lung vascular injury. Lung injury can be determined from the measured data when the point of osmotic equilibrium (where the indicator curve crosses the baseline) is significantly delayed as compared to the point of osmotic equilibrium plotted for a healthy lung.

In Situ Proteomic Analysis in Tissue Microwells

This technology provides for the simultaneous assessment of multiple tissue regions or microregions, the benefit being homogeneity of the sampling, both in terms of tissue content and timing. Discrete regions of a tissue sample, such as those demarcated by microwells formed within the tissue itself or tissue plugs removed from the tissue in a spatially referenced fashion, can be treated with one or more physical or chemical treatments to liberate target molecules of interest. Subsequent analysis of said target molecules by, e.g., mass spectroscopy, permits identification of a variety of biological parameters, including those associated with disease or therapy.

Diagnosing and Grading Gliomas Using a Proteomics Approach

This technology provides for a proteomic approach to grading gliomas, and for predicting patient survival. In addition to employing global protein expression patterns, such as by mass spectrometry, particular target proteins whose expression is altered in various gliomas can be used to predict the stage/classification of a glioma, as well as to indicate whether a given patient will be a short- or long-term survivor.
