Two Compartment Model for Detecting the Toxicity of Liver Metabolites

Overview Liver toxicity is a significant reason many new drugs fail in clinical trials. Primary human hepatocytes (PHHs) are the current gold standard for in vitro liver models; however, they have a number of limitations. We have invented an easy-to-use two-compartment device that provides in vitro 3D high-throughput prediction for safety assessments...

DNA Methylation Barriers

In normal differentiated cells, most of the genome is densely methylated, except CpG islands near promoters of actively transcribed genes. Maintaining this boundary between unmethylated promoter-associated and adjacent methylated regions is crucial as loss of segregation can lead to disease. Unfortunately, it is not clear where these boundaries are,...

Self-Expanding Stent for Valve Replacement

Aortic stenosis and aortic regurgitation are the most common types of aortic valvular diseases. Such diseased aortic valves in the body are traditionally replaced with valve prosthesis by an open surgical implantation. Available for licensing and commercial development is intellectual property covering stents for use with valve prostheses. As illustrated...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids

The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

JobViz: User Interface for Visualization of Majors & Jobs

Invention Summary: University (and industry) career search portals and web-based job search engines allow users to search on many items (e.g., education, location, level, etc.) and then present a text based list of potential job opportunities. University career portals are not as conductive to exploration by job and career searchers as they could...

Reconfigurable DNA Nano-Tweezer

Nanotechnology has grown by leaps and bounds in the past few decades. One of the main goals of nanotechnology is to build machines, switches or devices at the subatomic level that operate in a stimulus-responsive manner. Because DNA, via Watson-Crick pairing, is so precisely programmable, it is an ideal building block for creating such systems. In fact,...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers

Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices

Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...

Synthesize Highly Reactive Subnano-Sized Zero-Valent Iron using Smectite Clay Templates

IntroductionZero-valent iron is a reactive and powerful reducing agent capable of breaking down toxic compounds. More recently, nanoscale ZVI has emerged as a remediation technology used to degrade toxic chemicals. The nanoscale material (10-100 nanometer particle size) is often preferred because it has significantly more surface area than standard...
