A new nanofiber composite membrane morphology and fabrication scheme has been developed at Vanderbilt University to be used for alkaline anion-exchange membrane fuel cells (AAEMFCs). This membrane has high hydroxyl ion conductivity, good mechanical properties, long term chemical stability and low water swelling. Additionally it is well suited for harsh conditions including high temperature and low humidity.
Researchers at Vanderbilt University have developed a novel material with high adsorbent capacity for toxic industrial chemicals of low concentrations in air. Due to the broad range of chemicals that can be adsorbed at these capacities, this technology will replace existing commercial and research grade materials serving as respirator adsorbents and single pass filters for a variety of military and non-military applications.
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.
Elastography is the direct imaging of tissue elasticity parameters. The invention is a widely-applicable framework for determining elastic properties of tissue called Modality Independent Elastography (MIE). The technology is an adaptable framework which augments existing technologies (i.e. optical, magnetic resonance, computed tomographic, ultrasound) and creates image distributions of elastic parameters. It does not require any special sequences other than routine anatomical images.
Scientists at Vanderbilt developed a method of identifying of genes, which are necessary for viral growth in cells but nonessential for cellular survival, as well as the methods of treating viral infections based on modification of the function of such genes. The identification of such genes involves the creation of random mutations in single cellular genes by a method which allows the subsequent identification of the mutated gene; selection of cells which remain virus-free after exposure to virus by a method for selectively eliminating persistently infected cells; and subsequent identification of the single mutated gene which precluded viral infection. This invention can be used for identification of host proteins critical for single or multiple virus infection, identification of new molecular targets for antiviral agents and screening of novel antiviral agents.
It is estimated that approximately 30% of men have reduced fertility and 2% are totally infertile. Despite these large numbers relatively little is know about the molecular bases of male infertility. On the flip side of male infertility is the need for male contraception. Currently there are no reversible, convenient male contraceptives available. In order to develop male contraceptives and acquire a greater understanding of male fertility there is a need to develop animal models to study the molecular basis and pathways that regulate and control male fertility. Vanderbilt researchers have developed a model mouse system to study male fertility. There research focuses on the epididymus, which is the area that spermatozoa acquire the ability to move and fertilize. For this region to be functional tissue and cell specific gene regulation must occur. These investigators have discovered one such gene regulated within this area, mEP17. These researchers can fuse either mouse or human EP17 or just the regulatory regions of either EP17 to reporter genes and the resulting fusion can be used to screen for substances that regulate this gene and affect male fertility. This system becomes a powerful tool to identify drugs which affect this gene and be potential male contraceptives. In addition polypeptides generated to this gene may be used as vaccines for male contraceptives.
The Adventures of Jasper Woodbury™ consists of 12 videodisc-based adventures that focus on mathematical problem finding and problem solving. In particular, each adventure provides multiple opportunities for problem solving, reasoning, communication and making connections to other areas such as science, social studies, literature and history. Jasper adventures are designed for students in grades 5 and up. Each videodisc contains a short (approximately 17 minute) video adventure that ends in a complex challenge. The adventures are designed like good detective novels where all the data necessary to solve the adventure (plus additional data that are not relevant to the solution) are embedded in the story. Jasper adventures also contain "embedded teaching" episodes that provide models of particular approaches to solving problems.
Vanderbilt researchers have developed an optical system for the differentiation of normal and cancerous skin lesions. The system combines the diagnostic prowess of two separate techniques to provide non-invasive, real-time, in-situ evaluation of lesions.
A Vanderbilt team led by anesthesiologist Dr. Rajnish Gupta has developed a rapidly adjustable flexible positioning arm that can precisely position the ultrasound probe in such a way that it can be adjusted and fine-tuned with the flip of a switch. Upon fixing the probe in position, both of the clinician's hands are free to perform ultrasound guided procedures without the need for a second person to hold the probe.
We produced a plasmid containing the Fc portion of mouse IgGl (Fc) coupled to human fibroblast growth factor 1 (FGF-1). The plasmid was transformed into E. coli to express the fusion protein. The fusion protein was purified on a heparin sepharose column which has high affinity for the FGF portion of the fusion protein. The purpose of making this protein was to be able to identify cells that express receptors for FGF using flow cytometry.There are multiple fluorochrome labeled antibodies to mouse IgGl. When the fusion protein is bound to FGF receptors on cells, the Fc portion is on the surface of the cells and can be detected by fluorochrome labeled antibodies to mouse IgGl. Therefore, cells that express FGF receptors and bind the fusion protein can be detected by flow cytometry or immunofluorescence.
The invention is a cell line (Human embryonic kidney 293) stably expressing a recombinant human chloride channel (hClC-4). The cells enable high throughput screening of compounds that modulate chloride channel activity.
