| 20110045470 | PATHOGEN DETECTION IN LARGE-VOLUME PARTICULATE SAMPLES - Methods and filter systems for detecting microorganisms in a sample, such as a food sample, are disclosed. The filter is configured to attract the microorganism, for example by electrostatic charge. The filter containing the microorganism is incubated to grow the microorganism so that it may be detected. The filter may be degradable and the detection may involve extracting the microorganism or the molecular marker of the microorganism from the filter for detection. The filter system may also include a porous microbead component selected to trap dirt and other contaminants from the sample while allowing the microorganisms to pass among the microbeads. Methods are disclosed for detecting microorganisms in samples using the filter systems described. The methods may also include adding a polymer and/or a microorganism detection reagent to the filter to localize microorganism growth and prevent evaporation of reagents. | 02-24-2011 |

| 20090215064 | QUANTITATIVE ASSESSMENT OF INDIVIDUAL CANCER SUSCEPTIBILITY BY MEASURING DNA DAMAGE-INDUCED MRNA IN WHOLE BLOOD - Heparinized human whole blood from patients with invasive breast cancer, with (multiple primary) and without (single primary) a second primary cancer, and from unaffected controls was stimulated with 0.1-10 Gy of radiation and incubated at 37° C. for 2 hours. P21 and PUMA mRNA were then quantified. The results suggest that cancer susceptibility represented by the multiple primary cases was significantly related to over-reaction of p21 mRNA, and not PUMA. | 08-27-2009 |

| 20090111128 | METHOD FOR PREDICTING IMMUNE RESPONSE TO NEOPLASTIC DISEASE BASED ON mRNA EXPRESSION PROFILE IN NEOPLASTIC CELLS AND STIMULATED LEUKOCYTES - Tumor necrosis factor (TNF) is capable of inducing apoptosis by interacting with specific TNF receptors on the surface of cancer cells. Because multiple members of TNF ligand and receptor are present within each superfamily, over 300 different ligand-receptor combinations exist. Activated blood leukocytes produce TNF as part of the immune response to cancer, as well as producing chemokines to attract other leukocytes to the site. A method is disclosed of detecting significant induction of a variety of TNF superfamily subtype and chemokine mRNAs in blood leukocytes when whole blood is exposed to heat-aggregated IgG or anti-T cell receptor antibodies as a model of immune system interactions. Substantial individual-to-individual variation is observed in TNF subtypes and chemokines induced. Since peripheral blood leukocytes are the supply of anti-cancer immune cells, the quantitation of ex vivo inducibility of appropriate TNF ligands and chemokines in blood will be useful in individualized cancer immunotherapy. If the tumor mass is small, such as with early invisible metastatic lesions, appropriate TNF assaults may be sufficient to prevent relapse. | 04-30-2009 |
