Inventor: RODRIGUEZ VIEYTES MERCEDES
IPC: G01N21/64
Filed: 2004-07-21
Abstract: The invention relates to a quantitative method for detecting yessotoxins in fish products based on the activation caused by the toxin in cellular phosphodiesterase and therapeutic usefulness of said activation. The cellular target of yessotoxin (YTX) and analogues is the activation of phosphodiesterases (PDEs). The PDEs-YTX union emits a measurable signal. The union can be quantified by means of an affinity biosensor or fluorescence. The biosensor detects bimolecular interactions and makes it possible to determine the presence of YTX due to its interaction with PDEs. Plate fluorescence makes it possible to determine variations in the speed of degradation of fluorescent derivative anthranyloil-AMPc. The speed with which the PDEs degrade this molecule increases in the presence of YTX. The YTX inhibits the immunological activation of rat mastocytese and induces a cytotoxic effect in human hepatocarcinoma cells, which provides two therapeutic utilities of YTXs as anti-allergic and anti-tumoral compound.

Filed: 2004-09-29
Abstract: In one aspect, the present invention is directed to an osmotic pump that automatically provides an ascending release rate of active agent as the osmotic pump functions in an environment of operation and may be designed for implantation within a desired animal or human subject. An osmotic pump according to the present invention includes a reservoir, a rate controlling membrane, an expandable osmotic composition, an active agent formulation and an exit orifice. Once administered to an environment of operation, water passes through the rate controlling membrane and into the osmotic composition, which causes the osmotic composition to expand and expel the active agent formulation through the exit orifice at a rate that is directly proportional to the rate at which water passes through the rate controlling membrane. An osmotic pump according to the present invention permits the flow of water through the rate controlling membrane to increase automatically without the need for manipulation of the osmotic pump after administration. As the flow of water through the rate controlling membrane increases, the rate at which active agent is delivered from the osmotic pump will also increase proportionally.

Title: Increasing tcp re-transmission process speed
Inventor: MAKHER-VAKS VADIM
IPC: G06F15/16
Filed: 2004-12-06
Abstract: An RNIC implementation that performs direct data placement to memory where all segments of a particular connection are aligned, or moves data through reassembly buffers where all segments of a particular connection are non-aligned. The type of connection that cuts-through without accessing the reassembly buffers is referred to as a "Fast" connection because it is highly likely to be aligned, while the other type is referred to as a "Slow"  connection. When a consumer establishes a connection, it specifies a connection type (S2). The connection type can change from Fast to Slow and back. The invention reduces memory bandwidth, latency, error recovery using TCP retransmit and provides for a "graceful recovery" from an empty receive queue. The implementation also may conduct CRC validation (S11, S6) for a majority of inbound DDP segments in the Fast connection before sending a TCP  acknowledgement (Ack) confirming segment reception.
