Ultrasonic Sensor for Non-intrusive Local Temperature, Transient Temperature and Heat Flux Measurements

An apparatus for measuring the temperature and heat flux of materials through the use of an ultrasonic sensor has been developed at Vanderbilt University. The sensor uses acoustic measurement techniques to determine the heat flux and temperature of material surfaces otherwise inaccessible in particular during system operation in order to enhance monitoring capabilities and reduce unsafe or impaired function due to extreme temperatures.

Near-Infrared Dye with Large Stokes Shift for Simultaneous Multichannel in vivo Molecular Imaging

Fluorescent labels having near-infrared (NIR) emission wavelengths have the ability to penetrate tissue deeper than other emission wavelengths, providing enormous potential for non-invasive imaging applications. However, advancement of optical imaging (particularly NIR imaging) is hindered by the limitation of narrow Stokes shift of most infrared dyes currently available in the market. Vanderbilt researchers have developed a novel NIR dye (4-Sulfonir) for multichannel imaging that enables in vivo imaging of multiple targets due to its large Stokes shift. 4-Sulfonir with its unique large Stokes shift (~150 nm) and wide excitation spectrum could be used in parallel with other NIR dyes for imaging two molecular events simultaneously in one target.

Molecular Profiles for Subtyping Triple Negative Breast Cancer

Personalized medicine is at the forefront of medical news and specialized diagnostics that can align patients with the correct treatment are the key to this type of medicine. Jennifer Pietenpol and colleagues have performed extensive research and discovered that triple negative breast cancer (TNBC) is a heterogeneous disease with at least six subtypes. These subtypes have differing biological behaviors and sensitivities to known therapeutics. Diagnostic assays will help guide personalized and more effective therapy.

FOXA1 as a Biomarker for Urinary Bladder Cancer

In 2009 over 70,000 American were diagnosed with urinary bladder cancer, and in that same year over 14,000 Americans died of bladder cancer. Low funding for bladder cancer helps explain the slow progress in both the identification of biomarkers and the development of new treatments for metastatic bladder cancer. Nonetheless, novel diagnostic biomarkers are needed to aid in the early identification of patients with bladder cancer, and also to determine which patients are likely to progress. Vanderbilt researchers have identified such a biomarker whose expression is reduced and lost during progression of bladder cancer.

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.

'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.

A System for Growing Small Populations of Living Cells and Monitoring Their Physiological State

This invention combines the microfluidic and microelectronic devices and techniques required for the microminiaturization of cell culture and cell measurement systems to allow monitoring the response of populations of 1 to several hundred living cells. The instrument(s) allows for the detection of extracellular, membrane, and intracellular parameters; and the incorporation of closed-loop control techniques to continuously monitor the health of the cell and adjust the environmental and pharmacological parameters that control the cell.

Methods and Compositions to Assess Oxidative Brain Injury

A method to assess oxidative stress in vivo includes the steps of measuring an amount of neuroprostanes in a biological sample before the ex vivo development of neuroprostanes in a sample, comparing the measured amount of neuroprostanes with a control and assessing oxidative stress in vivo based on this comparison. There is also provided a marker for oxidated stress by an increase of neuroprostanes in a biological sample compared to a control sample. A diagnostic tool for determining the presence of a neurodegenerative disease provides for determining an increased amount of neuroprostanes in a biological sample compared to that of a control sample.

Transcend: Qualitative Diagnosis System & Method

Transcend is a model-based diagnosis system for fault detection and isolation of abrupt faults in complex to very complex engineered systems. It applies models of dynamic system behavior to obtain accurate predictions for measured transients and compares predictions with actual observations to distill the true cause for the faulty behavior. To successfully perform diagnosis, Transcend needs a dynamic model of the system.

Improved Piezoimmunosensor

An apparatus comprising one or more piezoelectric mass sensors for use in diagnostic and analytic processes, in particular for immunochemical detection of diagnostically relevant analytes in real time. Each piezoelectric mass sensor comprises a piezoelectric crystal with a receptor surface which has immobilized thereon a lawn of recombinant antibodies comprising single V.sub.H chain or single-chain Fv (scFv) polypeptides specific for a particular antigen. Binding of antigen to the recombinant antibodies results in a change in mass on the receptor surface which is detected as a change in resonant frequency. In a preferred embodiment, the receptor layer is a precious metal such as gold which facilitates self-assembly of the recombinant antibodies into a lawn on the receptor surface via a cysteine residue at the carboxy terminus of the attachment polypeptide.
