International Classification:

C07K 1447

US Classification:

530300, 530350

Abstract:

FAST-1 and Smad2 or Smad3 form a complex that is specifically induced by signals generated by a TGF- superfamily member. We have shown that a domain of FAST-1 directly interacts with Smad2 or Smad3, and that this interaction is mediated by specific domains of the two interacting molecules, namely, the MH2 domain of Smad2 or Smad3 and the Smad Interaction Domain (SID) of FAST-1. This result allows the development of methods and reagents for the isolation of compounds that are involved in, and/or modulate, TGF- superfamily signalling.

Abstract:

A combined X-ray and laser 3D imaging system for food safety inspection, which uses a 3D laser subsystem to get accurate depth information, which is further combined with an x-ray image to achieve accurate physical contamination detection in poultry and other meat products. A unique calibration model is used to calibrate the x-ray and laser 3D imaging systems at the same time. And a nested multi-thread software structure is implemented to prevent data conflict and ensure fully use of system resources during the physical contamination detection of the poultry and other meat products.

International Classification:

US Classification:

514013000, 514014000

Abstract:

Novel methods and compositions are provided for inhibiting interactions between human immunodeficiency viruses (HIVs) and viral coreceptors, including CXCR4 and/or CCR5 coreceptors. The anti-coreceptor binding agent includes a novel peptide portion of the gp120 envelope protein of HIV-1, as well as peptide analogs and mimetics of this peptide, that specifically binds to, or modulates activity of, the coreceptors(s). The anti-coreceptor binding agent is useful as a prophylactic or therapeutic treatment to prevent or inhibit HIV binding to a susceptible cell and thereby reduces infection and/or moderates or treats related diseases. In alternative embodiments, the peptides, analogs and mimetics are effective to inhibit direct co-receptor binding by HIV virus, coreceptor binding by HIV gp120 proteins or peptides, HIV fusion with target host cells, HIV virion entry into host cells, HIV replication, and HIV transmission between cells and hosts. In more detailed embodiments, the anti-coreceptor binding agents of the invention are multi-tropic by exhibiting activity against HIV interactions with multiple, CXCR4 and CCR5, coreceptors.

Abstract:

Microfluidic, electrochemical devices are described. The microfluidic, electrochemical device comprises one or more electrode(s) on a substrate and a patterned porous, hydrophilic layer having a fluid-impermeable barrier which substantially permeates the thickness of the porous, hydrophilic layer and defines boundaries of one or more hydrophilic channels within the patterned porous, hydrophilic layer, wherein the hydrophilic channel(s) comprises a hydrophilic region which is in fluidic communication with the electrode(s). In some embodiments, the electrodes comprise a working electrode, a counter electrode, and a reference electrode. In some embodiments, the microfluidic, electrochemical device further comprises a fluid sink. The method of assembling the microfluidic, electrochemical device is described. The method of using the device for electrochemical analysis of one or more analytes is also described.

International Classification:

B01J 19/00

US Classification:

60409, 422129, 422187

Abstract:

Self-regulating pressure source. The pressure source includes a chamber enclosing a chemical monopropellant. A moveable boss is attached to a deformable membrane sealing an air chamber, the moveable boss and air chamber being disposed within the chamber. A catalyst is disposed around the membrane so as to be covered by the boss in a retracted position so that the monopropellant is broken down by the catalyst to produce a gas. The gas pressure will increase within the chamber causing air in the air chamber to compress thereby to pull the boss into the retracted position to cover the catalyst thereby to regulate the pressure within the chamber. The self-regulating pressure source is particularly suited to power fluidic elastomeric actuators.

International Classification:

US Classification:

101288

Abstract:

A method of printing on a release layer of linerless label material including the step of advancing linerless label material and a thermal transfer ribbon coated with ink through a thermal printer. The ribbon is moved over a heated transfer element of the printer. The heated transfer element is located on an edge or on a corner of an edge of the thermal printer. The ribbon is then heated to cause the ink to reach a molten or fluid state. The ink transfers in its molten or fluid state to the release layer of the linerless label material. Certain wax/resin and resin based thermal transfer ribbons and silicone release coatings have been found to be particularly effective for increasing the ink transfer and anchorage during corner edge and true edge printing on linerless label material.
