  • Genomic markers of hepatitis B virus associated with hepatocellular carcinoma
    Patent number: 7871780
    Abstract: The present invention provides methods of predicting a pre-disposition of HBV-infected individuals to develop hepatacellular carcinoma (HCC).
    Type: Grant
    Filed: September 10, 2008
    Date of Patent: January 18, 2011
    Assignees: The Chinese University of Hong Kong, The Hospital Authority
    Inventors: Jao Yiu Joseph Sung, Lik Yuen Chan, Kwok Wing Stephen Tsui, Kwong Sak Leung, Shu Kam Tony Mok, Angeline Bartholomeusz, Wai Yee Nancy Leung, Kin Hong Lee
  • Generation and applications of negative dielectric constant materials
    Patent number: 7611969
    Abstract: A negative dielectric is induced by the application of a dc bias-electric field in aggregates of oxide nano-particles whose surfaces have been specially treated. The magnitude of the dielectric constant and the frequency where the negative dielectric constant occurs can be adjusted. Such material systems have profound implications in novel devices as well as in science development, e.g. unusual wave propagation, secured communication and ultra-high temperature superconductivity.
    Type: Grant
    Filed: February 17, 2006
