Publication number: 20160206615Abstract: The invention provides pharmaceutical formulations of inhibitors for poly (ADP-ribose) polymerase (PARP) enzyme. The formulations can be used in the treatment and prevention of cancer as well as the treatment of neurotrauma and neurodegenerative diseases. The PARP inhibitor is delivered in the form of nanoparticles that provide efficient delivery of the inhibitor into cancer cells or other cells and release of the inhibitor within the cells. In treating cancer, the result is killing of tumor cells, whereas in treatment of neurotrauma and neurodegenerative disease, the result is preservation of cell function.Type: ApplicationFiled: August 27, 2014Publication date: July 21, 2016Inventors: Shifalika TANGUTOORI, Srinivas SRIDHAR

Publication number: 20110024719Abstract: Nanoelements such as single walled carbon nanotubes are assembled in three dimensions into a nanoscale template on a substrate by means of electrophoresis and dielectrophoresis at ambient temperature. The current-voltage relation indicates that strong substrate-nanotube interconnects carrying mA currents are established inside the template pores. The method is suitable for large-scale, rapid, three-dimensional assembly of 1,000,000 nanotubes per square centimeter area using mild conditions. Circuit interconnects made by the method can be used for nanoscale electronics applications.Type: ApplicationFiled: April 13, 2009Publication date: February 3, 2011Inventors: Srinivas Sridhar, Evin Gultepe, Dattatri Nagesha
