Electronic detection of ligand-receptor interactions

Technology OverviewThis biosensor technology enables the direct electrical detection of molecules in solution. Detection is accomplished by the simultaneous monitoring of several dielectric parameters – including capacitance, dissipation factor, conductance, impedance, and phase – over a selected alternating current frequency range. The res...

Rapid Test for Dental Caries Risk

Technology OverviewResearchers at the OHSU School of Dentistry have developed methods and kits to rapidly detect the presence of dental cavity causing bacteria in dental plaque and/or saliva and to assess the risk in a patient of developing dental cavities based upon the presence of one or more species of cavity causing bacteria. This method is...

Ultrasound Based Approach to Diagnosing Heart Failure

Technology Overview Right ventricular (RV) function has prognostic significance in heart failure, and RV dysfunction has been shown to predict reduced exercise capacity and survival. Current non-invasive methods to evaluate RV function include echochardiography (the most common), MRI, high frequency thermodilution, contrast ventriculography, a...

Profiling circulating fragments of fibrillin-1, fibrillin-2, and fibulin-4 as biomarkers for disease

Technology Overview Fibrillin-1, fibrillin-2, and fibulin-4 are molecular components of elastic fibers and microfibrils. Elastic fibers and microfibrils are stable structures especially abundant in the connective tissues of blood vessels, lung, skin, ligaments and tendons, and the eye. As a result of disease processes, these structures can be ...

Contrast-Enhanced Magnetic Resonance Imaging for Detection and Quantification of Fibrosis in Human Myocardium

Technology Overview Myocardial fibrosis is a morphologic change common to multiple cardiac disease conditions. In addition to replacement (scar) fibrosis, there is increasing recognition of interstitial (reactive) fibrosis acting as an important player in structural remodeling of the diseased heart, as well as the genesis of fatal arrhythmia l...

Algorithm For Automated Detection of Melanoma

Technology Overview Comprehensive diagnosis of melanoma typically requires both reliable histopathology and the trained eye of a clinician for assessment. With optical (as opposed to physical) sectioning of tissue and OHSU created software to process confocal images, it is possible to distinguish the diagnostic traits of malignancy, such as ...

Gene Polymorphisms Associated with Increased Risk of Hyponatremia

Technology Overview: This technology provides methods of diagnosing an increased risk for hyponatremia by assessing the presence of at least one hypofunctioning allele of TRPV4. Abundant evidence suggests that the transient receptor potential channel TRPV4 comprises an element of the central sensor of low osmolality. A large cohort of patients...

Mold Infections Diagnosis

In the past two years, a new disease Jejunal Hemorrhage or Dead gut Syndrome has appeared in dairies across the United States. Often this disease affects only adults and cows are dead within 24 hours. A precise method has not been developed and symptoms of gastrointestinal disorders in ruminants overlap. This new invention will allow rapid dia...
