Storing and querying general data type documents in SQL relational databases
Many types of data files can only be stored in SQL databases as Blobs—Binary Large Objects, that the database can only handle as a whole. This limits searches within the Blob. Here improved methods are taught for automatically analyzing potential Blob files, and assigning at least certain classes of potential Blob files to General Data Type documents. In some cases, the potential Blob may be automatically analyzed and mapped to a JSON document type, and this JSON document type then automatically mapped into appropriate lists of JSON-document-nodes and tables that can be stored in the SQL database, and subsequently queried. This enables much data within the (to prior art) Blob to be queried at more detailed granularity. This data can then be retrieved and used to reconstruct some or all of the original General Data Type document, which would otherwise be a Blob to prior art methods. |

The query to the data store is passed to the data store, and a handle to memory location is received from the data store at which the data store has temporarily stored a message including the opaque objects. The opaque objects are added to the cache by treating the memory location as a cache entry for the opaque objects. Cache metadata for the cache entry is generated, and along with the handle is stored within a metadata cache entry of a metadata cache structure separate from the message. The handle and the cache metadata can be returned to the application, where the cache metadata can be returned as an opaque context of the cache entry. |

Monoclonal antibody neo-201 for the treatment of human carcinomas
NEO-201 is a humanized IgG1 monoclonal antibody (mAb) that is highly reactive against the majority of tumor tissues from many different carcinomas, including colon, pancreatic, stomach, lung, breast, and uterine cancers, but the overwhelming majority of normal tissues are not recognized by this antibody. Functional assays revealed that NEO-201 is capable of mediating both antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) against tumor cells. Furthermore, the growth of human pancreatic xenograft tumors in vivo was largely attenuated by treatment with NEO-201 both alone and in combination with human peripheral blood mononuclear cells (PBMC) as an effector cell source for ADCC. In vivo biodistribution studies in human tumor xenograft-bearing mice revealed that NEO-201 preferentially accumulates in the tumor but not organ tissue. A single-dose toxicity study in non-human primates demonstrated safety and tolerability of NEO-201, as a transient decrease in circulating neutrophils was the only related adverse effect observed. |
