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.

Thrombosis is the formation of a blood clot inside a blood vessel, which may cause reduced blood flow to a tissue, or even tissue death. Thrombosis, inflammation, and infections are responsible for >70% of all human mortality. Thrombosis is also the major factor for heart disease and stroke. 500,000 die from thrombosis every year in Europe. Inhibitory treatment of these conditions may also improve the outcomes of several non-fatal diseases. Researchers from Vanderbilt University and Oregon Health & Science University have jointly discovered new monoclonal antibodies that potently inhibit the blood coagulation protein factor XII (FXII), a critical player in the pathway, and anticoagulate blood. This invention provides foundation for commercial development of anti-thrombotic drugs based on new molecular entities.
Heart valve disease is the 3rd most prevalent source of cardiovascular disease, leading to approximately 20,000 deaths per year in the U.S. alone. Moreover, there are an estimated 41,000 mitral valve procedures performed in the U.S. each year. The only effective, long-term treatment for mitral valve disease is open-chest valve replacement surgery, which is highly undesirable for elderly patients. Thus, there is a pressing need to develop novel percutaneous strategies for treatment that will reduce the number of open-chest surgeries. David Merryman and colleagues have developed a new, combined catheter that uses cryo temperatures to adhere to moving mitral valve leaflets and radiofrequency ablation to alter the compliance of the leaflet tissue to prevent prolapse and regurgitation.
This invention relates generally to a method of identifying an individual having an increased susceptibility to developing Familial Primary Pulmonary Hypertension (FPPH), as well as to a method for diagnosing an individual suffering from FPPH. The invention also relates to a method of identifying an individual having an increased susceptibility to developing (non-familial) Primary Pulmonary Hypertension (PPH), as well as to a method for diagnosing an individual suffering from PPH.
This technology facilitates the discovery and design of novel agents for either repelling or otherwise controlling insects that have important economic or medical significance. In particular, mosquitoes are responsible for transmitting a number of diseases, including malaria, West Nile, dengue and yellow fevers. The Zwiebel laboratory has identified human odorants and the protein receptors in mosquitoes that allow female mosquitoes to identify their hosts when they need blood to satisfy their reproductive needs. With funding from the Gates Foundation's Grand Challenge in Global Health initiative, the Zwiebel laboratory, along with collaborators at Yale, Wageningen University in the Netherlands, and researchers in Africa, developed biological and behavioral assays to screen and test numerous agents as potential repellants and attractants for the Anopholes gambiae mosquito. These methods have been applied to include agricultural pests, disease vectors and nuisance insects (important for many tourist-based economies).
Phosphodiesterase-5 (PDE5) is an enzyme which degrades cyclic guanosine monophosphate (cGMP) in smooth muscle cells. The common known drug Viagra is similar in molecular structure to cGMP and acts as a competitive binding agent of PDE5. Thus in the presence of Viagra unbound cGMP levels increase which results in smooth muscle relaxation or vasodilation leading to an increased inflow of blood. Vanderbilt researchers have developed a method for assaying compounds which bind PDEs. Not only will this method be useful in identify other PDE inhibitors but due to the high affinity of this system this method could be used to identify and isolate PDEs from various crude tissue fractions.
