20150361507 | TERT PROMOTER MUTATIONS IN GLIOMAS AND A SUBSET OF TUMORS - We surveyed 1,230 tumors of 60 different types and found that tumors could be divided into types with low (<15%) and high (≧15%) frequencies of TERT promoter mutations. The nine TERT-high tumor types almost always originated in tissues with relatively low rates of self renewal, including melanomas, liposarcomas, hepatocellular carcinomas, urothelial carcinomas, squamous cell carcinomas of the tongue, medulloblastomas, and subtypes of gliomas (including 83% of primary glioblastoma, the most common brain tumor type). TERT and ATRX mutations were mutually exclusive, suggesting that these two genetic mechanisms confer equivalent selective growth advantages. In addition to their implications for understanding the relationship between telomeres and tumorigenesis, TERT mutations provide a biomarker for the early detection of urinary tract and liver tumors and aid in the classification and prognostication of brain tumors. | 12-17-2015 |

20110311500 | COMBINATION BACTERIOLYTIC THERAPY FOR THE TREATMENT OF TUMORS - Current approaches for treating cancer are limited, in part, by the inability of drugs to affect the poorly vascularized regions of tumors. We have found that spores of anaerobic bacteria in combination with agents which interact with microtubules can cause the destruction of both the vascular and avascular compartments of tumors. Two classes of microtubule inhibitors were found to exert markedly different effects. Some agents that inhibited microtubule synthesis, such as vinorelbine, caused rapid, massive hemorrhagic necrosis when used in combination with spores. In contrast, agents that stabilized microtubules, such as the taxane, docetaxel, resulted in slow tumor regressions that killed most neoplastic cells. Remaining cells in the poorly perfused regions of tumors could be eradicated by sporulated bacteria. Mechanistic studies showed that the microtubule destabilizers, but not the microtubule stabilizers, radically reduced blood flow to tumors, thereby enlarging the hypoxic niche in which spores could germinate. A single intravenous injection of spores plus selected microtubule-interacting agents was able to cause regressions of several tumors in the absence of excessive toxicity. | 12-22-2011 |

We tested these samples to detect somatic mutations present in rare tumor cells that might accumulate in the cervix once shed from endometrial and ovarian cancers. A panel of commonly mutated genes in endometrial and ovarian cancers was assembled and used to identify mutations in all 46 endometrial or cervical cancer tissue samples. We were able also able to identify the same mutations in the DNA from liquid Pap smears in 100% of endometrial cancers (24 of 24) and in 41% of ovarian cancers (9 of 22). We developed a sequence-based method to query mutations in 12 genes in a single liquid Pap smear without prior knowledge of the tumor's genotype. | 10-15-2015 |

20150227628 | RECURSIVE UNIQUE USER METRICS IN REAL TIME - A system can provide unique user metrics associated with a node in a hierarchy and the node's decedents in real time. This can occur by merging sketches of the node and its decedents to form a merged sketch, and retrieving the unique user metrics from the merged sketch. The sketches and the merged sketch may each be a separate data form, such as a hash. The hierarchy may include an online content taxonomy and the sketches of each node may include unique user metrics associated with the node, such as user interaction metrics associated with a category of content of the node. The system may build sketches for the nodes of a hierarchy, associate each sketch with its ancestor sketches, invert the associations, tie corresponding descendant sketches of an ancestor sketch based on the inversions, and merge the descendant sketches with their ancestor sketches to generate the merged sketches. | 08-13-2015 |

20080281815 | OPTIMAL STORAGE AND RETRIEVAL OF XML DATA - A document management system manages a large number of XML documents on an efficient and cost-effective basis. Storage requirements are reduced, because compressed versions of the XML documents, which are much smaller in size than the XML documents themselves, are used when processing queries. Processing requirements are reduced, because parsing is not a required step when processing queries. Instead of parsing, the query is processed by unpacking the compressed version of the document identified in the query, node by node until enough information has been decoded to satisfy the query. Processing speed is improved in two ways. First, unpacking as carried out according to the invention is a much faster process than parsing. Second, the entire document need not be unpacked. | 11-13-2008 |
