  • Method for removing contaminants from water using ruthenium based contaminant sorbents and oxidizers
    Patent number: 7335307
    Abstract: Ruthenium compounds, either alone or in combination with other remediating compounds, can be used to oxidize, remove and sequester contaminants in water and soil or sediments.

  • Genetic testing for male factor infertility
    Publication number: 20060199204
    Abstract: RNA in sperm can be used as a diagnostic to distinguish between normal and affected individuals. A list of specific diagnostic transcripts is provided which is compared with transcripts obtained from the sperm of a subject. Correlation between the two transcripts is used to identify normal sperm or affected sperm. Addition, genetic testing for male infertility or damage to spermatozoa is accomplished by providing a microarray of DNA probes with a sample of spermatozoa to determine the mRNA fingerprints of the sample, and comparing the mRNA fingerprints of the sample with the mRNA fingerprints of normal fertile male spermatozoa.
