Methods for Controlled Recovery of Useful Materials from Nuclear Fuels
Invention SummaryThe methods would allow nuclear materials—lanthanides and actinides—to be dissolved directly into ionic liquid for electrochemical recovery, reducing the number of steps and the negative influence of water in the process. The same ionic liquid serves as an electrochemical bath for the plating of actinides and lanthanides...

Method for Predicting the Efficacy of Anti-Cancer Drugs
Invention SummaryThe invention provides the first efficient method for simultaneously measuring the anti-migratory effect and cytotoxic effect of drugs on biopsy cells without the need to expand the cells in culture. This assay is particularly useful for predicting the chemosensitivity of an individual patient's cancer to therapeutic drugs. Single cell...

DNA Molecules and Polypeptides of Pseudomonas Syringe Hypersensitive Response and Pathogenicity
Invention SummaryThe bacterium Pseudomonas syringae is noted for its diverse and host-specific interactions with plants. In host plants, the bacteria typically grow to high population levels in leaf intercellular spaces and then produce necrotic lesions. In non-host plants or in host plants with race-specific resistance, the bacteria elicit a hypersensitive...

Cancer Treatment by Phenyl Boric Acid
Invention SummaryThe technology relates to chemotherapeutics. Phenyl boric acid, its salts, and substituent derivatives (e.g., substituted phenyl) effectively inhibit the growth of several cancer cell lines and offer utility in the treatment/prevention of cancer. The material may be applied or injected into affected areas or applied topically, especially...

Decrease Toxic Metal Residues in Medicine (N-Heterocyclic Phosphines)
Invention SummaryThe invention is a new synthetic method for generation of P-C bonds (phosphorus-carbon bonds) with transition-metal-free reaction conditions. Phosphorus carbon bonds are often found in pharmaceuticals and antimicrobial natural products. Accordingly, creation of P-C bonds under metal-free reaction conditions would be highly desirable...
