The methodology and system can be applied to any commercially available MRI scanner.
Potential Commercial Applications:
* Early detection of vascular disease,
* Research in the field of vascular disease,
* Non-invasive assessment of the efficacy of medication and/or lifestyle changes in vascular health status in a particular subject, and
* Assessment of the efficacy of new medications or new uses of existing medications to treat vascular disease.
Competitive Advantages:Existing techniques suffer from image degradation due to aperiodic intrinsic cardiac, chest wall motions, or other bulk motion that often cause image blur and reduced wall sharpness. These techniques do not adequately address the time-dependent angular orientation of the arteries, whereby mispositioning of the imaged slice may cause disappearance of the lumen-wall interface altogether.
In the new technology time-resolved arterial wall imaging overcomes the loss of the orthogonality due to uncompensated residual motion.
* In vivo data available (human).

Topical Antibiotic With Immune Stimulating Oligodeoxynucleotide Molecules To Speed Wound Healing
Description of Technology:The present technology provides a mean of improving the activity of topical antibiotics. Currently available topical antibiotic formulations effectively eliminate bacteria at a wound site. But in eliminating bacteria in the wound, such antibiotics also eliminate the molecular signals present in bacterial DNA that stimulate to immune system's wound healing processes. Without these signals the rate of wound healing is diminished. It would be desirable for topical antibiotics to remove infectious bacteria but also provide the immune stimulating signals needed to promote and accelerate healing. The present formulation accomplishes these goals by supplementing the antibiotic formulation with immunostimulatory oligodeoxynucleotides (ODN). These ODN express the CpG motifs present in bacterial DNA and safely mimic the immune stimulation induced by bacterial DNA. The formulation may be applied directly to a wide variety of wounds to skin (such as traumatic, burn, or surgical wound), or the eyes (such as corneal abrasions) to effectively eliminate infection and stimulate rapid healing of the wound.
Potential Commercial Applications:Topical antibiotic.
Competitive Advantages:Eliminates wound site bacteria while retaining immune stimulating properties that promote faster wound healing.
* In vivo data available (animal).

Antimalarial Inhibitors That Target the Plasmodial Surface Anion Channel (PSAC) Protein and Development of the PSAC Protein as Vaccine Targets
Description of Technology:There are two related technologies, the first being small molecule inhibitors of the malarial plasmodial surface anion channel (PSAC) and the second being the PSAC protein itself as a vaccine candidate. The PSAC protein is produced by the malaria parasite within host erythrocytes and is crucial for mediating nutrient uptake. In vitro data show that the PSAC inhibitors are able to inhibit growth of malaria parasites, have high specificity, and low toxicity. Portions of the PSAC protein are found on the outer surface of infected host erythrocytes and the protein was recently shown to be encoded by the clag3 gene. This discovery opens the possibility of developing the PSAC protein as a potential vaccine candidate against malaria.
Potential Commercial Applications:
* Antimalarial Drugs.
* Malaria Vaccine.
* Novel target against malaria.
* Small molecule inhibitors of PSAC inhibit malarial parasite growth, have low toxicity, and high specificity.
* PSAC protein is exposed on the surface of the infected host erythrocytes, making it an attractive vaccine candidate.
* In vitro data available.

Fluorescent Magnesium Indicators
Description of Technology:A non-invasive approach in which Magnesium (Mg2+) ion levels can be measured in real-time. Mg2+ is essential to many physio-chemical processes and plays a central role in the biochemistry of all cells. Many epidemiological studies have established close association between plasma magnesium levels and various diseases including cardiovascular disease and hypertension. However, methods and tools to selectively measure cellular magnesium levels in the body with accuracy and reliability are still lacking in the market today. The present invention provides novel fluorescent indicators (carboxy-quinolizones) that are selective for Mg2+ and can be easily detected using fluorescence spectroscopy.
Current approaches used to measure intracellular magnesium in the body generally involve magnetic resonance spectroscopy, which is extremely expensive and subject to very poor accuracy. Unlike these other methods, the fluorescence indicators of this invention provide a more accurate way to measure intracellular and extracellular Mg2+ levels in a wide variety of biological settings and have potential to be developed into diagnostic reagents.
Potential Commercial Applications:
* Tool for measuring intracellular and extracellular magnesium levels.
* Diagnostic reagent for measuring magnesium levels in a human or animal.
* Increased accuracy compared to what is available on the market.
* Detection is noninvasive.
* Ease of use.
* In vitro data available.
