Patents by Inventor Donald C. Malins

Donald C. Malins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040089809
    Abstract: Methods of screening for a tumor or tumor progression to the metastatic state are disclosed. The screening methods are based on the characterization of DNA by principal components analysis of spectral data yielded by Fourier transform-infrared spectroscopy of DNA samples. The methods are applicable to a wide variety of DNA samples and cancer types. A model developed using multivariate normal distribution equations and discriminant analysis is particularly well suited for distinguishing primary cancerous tissue from metastatic cancerous tissue.

  • Patent number: 5665553
    Abstract: Methods for determining the genotoxic or carcinogenic status of a subject by analyzing the cellular redox potential of a test specimen where an increased risk of, or presence of, genotoxic injury or cancer is indicated when the cellular redox potential favors oxidatively derived modified nucleotide bases. A sensitive method is disclosed wherein DNA is isolated from a test specimen obtained from a test subject and assayed for modified nucleotide bases that have formed either stable reductively formed derivatives or stable oxidatively formed derivatives. By identifying and comparing those modified nucleotide bases derived via reductive pathways to those modified nucleotide bases derived via oxidative patwhays, a determination as to the cancer status of the test specimen can be made wherein a greater cancerous state exists when the ratio between the two species of modified nucleotide bases indicates that oxidatively formed derivative are favored over reductively formed derivatives.
