Patent CA-2137878-A1 (CA)
Title: Photosensor with multiple light sources
Inventor: GRATTON ENRICO
IPC: A61B5/00
Filed: 1994-12-12
Abstract: The quantitative determination of various materials in highly scattering media such as living tissue may be determined in an external, photometric manner by the use of a plurality of light sources positioned at differing distances from a sensor. The light from said sources is amplitude modulated, and, in accordance with conventional frequency domain fluorometry or phosphorimetry techniques, the gain of the sensor is modulated at a frequency different from the frequency of the light modulation. Data may be acquired from each of the light sources at differing distances at a frequency which is the difference between the two frequencies described above. From these sets of data from each individual light source, curves may be constructed, and the slopes used to quantitatively determine the amount of certain materials present, for example oxyhemoglobin and deoxyhemoglobin in living tissue, or to determine at least the relative concentration of a material such as glucose.

Title: Dna profiles as an indicator of cellular redox potential and cancer risk
Inventor: MALINS DONALD C
IPC: C12Q1/68
Filed: 1994-04-29
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 pathways, 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. Also disclosed are methods for modulating the cellular redox potential so as to decrease the likelihood of oxidatively derived modified base formation and cancer formation. Methods for monitoring the efficacy of such therapy are additionally disclosed.
