Abstract: Methods for modification of abnormal protein interactions manifested as excessive PACT-mediated PKR activation within cells are described. Methods include administration of luteolin to cells that exhibit dysregulation in PACT-mediated PKR activation. Methods can decrease or prevent excessive non-viral PACT-mediated PKR activation in a cell as may occur due to expression by the cell of a mutant PACT protein. Methods can decrease an abnormal prolonged stress response as may occur in the absence of a stress-inducing activity or agent.

Abstract: Methods are provided for using a combination of nanomaterials and oil-degrading bacteria to detoxify a multiphasic liquid (e.g., an oil-water mixture) and to ameliorate the toxicity of oil to local organisms, e.g., meiobenthos, in or near the area of the multiphasic liquid. The methods can be utilized for oil recovery and environmental clean-up and detoxification after spills and discharges. Through synergistic combination of the nanomaterials with oil degrading bacteria, methods can ameliorate environmental damage due to the presence of oil in an area through increased activation of the bacteria as well as through removal of the oil.
Abstract: Described herein are devices and methods for performing automated and minimally invasive intramyocardial injections for cardiac repair that eliminate the need for opening the chest cavity for injections of therapeutics to the heart muscle to address heart attack, cardiomyopathy or myocardial diseases and can detect diseased tissue and deliver a specified volume of a therapeutic injectate to the region of interest.

Abstract: Described herein are diagnostic methods and systems employing a sensor added to an ultrasound probe to measure the pressure/force being applied to the patient by the probe during ultrasound scanning, feedback of the probe contact pressure measurement will provide sonographers an opportunity to make probe pressure adjustments to both capture a quality image and minimize discomfort to the patient, as well as enhance the diagnostic capability of other forms of ultrasound.
Abstract: Novel markers that can be attached physically to a tensile specimen with a center guide to allow for measuring correct strain, as well as a binder that fixes and holds a pin guide to its location on the specimen during the test.
Abstract: A connector for joining concrete structures such as double tee beams to one another. The connector includes a curved bolt that is formed with a shape memory alloy. Through utilization of the bolt, a joint can be post-tensioned following assembly through application of heat to the joint. Post-tensioning can be reapplied following loosening of the joint through application of heat. When considering a super elastic shape memory alloy, the bolt can be a smart bolt that can self-correct following deformation due to excessive load.
Abstract: Disclosed are redox flow battery membranes, redox flow batteries incorporating the membranes, and methods of forming the membranes. The membranes include a polybenzimidazole gel membrane that is capable of incorporating a high liquid content without loss of structure that is formed according to a process that includes in situ hydrolysis of a polyphosphoric acid solvent. The membranes are imbibed with a redox flow battery supporting electrolyte such as sulfuric acid and can operate at very high ionic conductivities of about 100 mS/cm or greater. Redox flow batteries incorporating the PBI-based membranes can operate at high current densities of about 100 mA/cm2 or greater.

Abstract: Disclosed are methods for forming a supported catalyst and catalysts formed according to disclosed methods. Methods include contacting a catalyst support with a precursor solution and displacing the solvent of the precursor solution (e.g., water) with a second solvent that has a lower surface tension than the first solvent. The second solvent displaces the first solution according to the Marangoni effect. Methods also include activation of the precursor to form a catalyst, e.g., a supported platinum group metal catalyst or the like.
