Patent number: 7297539Abstract: This disclosure provides an improved system for culturing human pluripotent stem cells. Traditionally, pluripotent stem cells are cultured on a layer of feeder cells (such as mouse embryonic fibroblasts) to prevent them from differentiating. In the system described here, the role of feeder cells is replaced by components added to the culture environment that support rapid proliferation without differentiation. Effective features are a suitable support structure for the cells, and an effective medium that can be added fresh to the culture without being preconditioned by another cell type. Culturing human embryonic stem cells in fresh medium according to this invention causes the cells to expand surprisingly rapidly, while retaining the ability to differentiate into cells representing all three embryonic germ layers. This new culture system allows for bulk proliferation of pPS cells for commercial production of important products for use in drug screening and human therapy.Type: GrantFiled: June 21, 2004Date of Patent: November 20, 2007Assignee: Geron CorporationInventors: Ramkumar Mandalam, Chunhui Xu

Patent number: 7297551Abstract: Recombinant fragments of Factor C are disclosed. These proteins and peptides show great potency in recognizing, binding to, neutralizing and removing endotoxin. These molecules can thus be used for anti-microbial, anti-endotoxin, and anti-sepsis therapy. SSCrFCES is a 38 kDa protein representing the LPS-binding domain of Factor C. The ability of SSCrFCES to bind lipid A was analyzed using an ELISA-based assay as well as surface plasmon resonance. Surface plasmon resonance similarly carried out for SSCrFC-sushi-1,2,3-GFP, SSCrFC-sushi-1GFP, and SSCrFC-sushi-3GFP confirmed their superior affinity for endotoxin. The 50% endotoxin-neutralizing concentration of SSCrFCES against 200 EU of endotoxin is 0.069 ?M, suggesting that SSCrFCES is an effective inhibitor of LAL coagulation cascade. Although partially attenuated by human serum, as low as 1 ?M of SSCrFCES inhibits the LPS-induced secretion of hTNF-? and hIL-8 by THP-1 and human pheripheral blood mononuclear cells with a potency more superior than polymyxin B.Type: GrantFiled: August 7, 2003Date of Patent: November 20, 2007Assignee: National University of SingaporeInventors: Jeak L.

Patent number: 7297571Abstract: The field of the invention is that of microsystems of the electrostatically actuated microswitch type that are used in electronics to carry out switching functions, especially in the microwave field for mobile telephony and radars. The object of the invention is to improve the performance of the switch by reducing the response time of the device and by increasing the radiofrequency or microwave power supported, while still maintaining low switching voltages. This improved performance is obtained by using thick membranes and by placing a material of high relative permittivity between said membrane and the associated electrode. The switch is obtained by a novel production process, the membrane being produced on an independent substrate and then joined to the base substrate of the switch. Examples of processes for producing devices according to the invention with the materials that can be used, the possible geometries and the various production steps are given.Type: GrantFiled: September 26, 2003Date of Patent: November 20, 2007Assignee: ThalesInventors: Afshin Ziaei, Thierry Dean, Jean-Philippe Polizzi

Patent number: 7297572Abstract: This specification describes techniques for manufacturing an electronic system module. The module includes flexible multi-layer interconnection circuits with trace widths as narrow as 5 microns or less. A glass panel manufacturing facility, similar to those employed for making liquid crystal display, LCD, panels is preferably used to fabricate the interconnection circuits. A multi-layer interconnection circuit is fabricated on the glass panel using a release layer. A special assembly layer is formed over the interconnection circuit comprising a thick dielectric layer with openings formed at input/output (I/O) pad locations. Solder paste is deposited in the openings using a squeegee to form wells filled with solder. IC chips are provided with gold stud bumps at I/O pad locations, and these bumps are inserted in the wells to form flip chip connections. The IC chips are tested and reworked. The same bump/well connections can be used to attach fine-pitch cables.Type: GrantFiled: November 5, 2003Date of Patent: November 20, 2007Assignee: Hynix Semiconductor, Inc.Inventor: Peter C. Salmon
