Abstract:
The present invention relates to immunogenic compositions comprising a recombinant Neisseria gonorrhoeae OpcA and methods of eliciting an immune response in a mammal by administering a formulation comprising N. gonorrhoeae OpcA or a portion or fragment of N. gonorrhoeae OpcA. The invention also provides for methods and kits for diagnosing N. gonorrhoeae infection using said recombinant N. gonorrhoeae OpcA.
Abstract:
Methods to fabricate high aspect ratio powder composite microstructures is provided by filling a molding composition containing a powdered material and a binder into a patterned mold, and releasing the cured composite microstructures from the mold. An alternate method is by filling a mix of powdered dense metals and low-melt alloys into a patterned mold, and releasing the melted and solidified composite microstructures from the mold. The mold is derived from lithographically defined parent mold. One example of the application is in the field of x-ray anti-scatter grids and nuclear collimators.
Abstract:
The invention provides a mixing flow apparatus. The mixing flow apparatus consists of a waveguide and a mixing flow chamber; the waveguide having a higher index of refraction material than its surroundings for propagation of a signal, and the mixing flow chamber having a body forming a flow chamber with an inlet, an outlet, a radiation transmissive wall and a surface positioned to disrupt flow regularity of a sample fluid, the body of the mixing flow chamber surrounding at least a portion of the waveguide, wherein constituents of a sample fluid entering the inlet are mixed by disruption of sample fluid flow regularity prior to discharge at the outlet. Also provided is a detection apparatus. The detection apparatus consists of a waveguide, a mixing flow chamber and a radiation detector; the waveguide having a higher index of refraction material than its surroundings for propagation of a signal; the mixing flow chamber having a body forming a flow chamber with an inlet, an outlet, a radiation transmissive wall and a surface positioned to disrupt flow regularity of a sample fluid, the body of the mixing flow chamber surrounding at least a portion of the waveguide, wherein constituents of a sample fluid entering the inlet are mixed by disruption of sample fluid flow regularity prior to discharge at the outlet, and the radiation detector being disposed facing the direction of oncoming propagated signal from the waveguide. The detection apparatus can include an illumination source.

Abstract:
Grids (30) and collimators, for use with electromagnetic energy emitting devices (61), include at least a metal layer that is formed, for example, by electroplating/electroforming or casting. The metal layer includes top and bottom surfaces, and a plurality of solid integrated walls (32). Each of the solid integrated walls extends from the top to bottom surface and has a plurality of side surfaces. The side surfaces of the solid integrated walls are arranged to define a plurality of openings (31) extending entirely through the layer. At least some of the walls (32) also can include projections extending into the respective openings formed by the walls (32). The projections can be of various shapes and sizes, and are arranged so that a total amount of wall material intersected by a line propagating in a direction along an edge of the grid (30) is substantially the same as another total amount of wall material intersected by another line propagating in another direction substantially parallel to the edge of the grid (30) at any distance from the edge. Methods to fabricate these grids (30) using copper, lead, nickel, gold, any other electroplating/electroforming materials or low melting temperature metals are described.
Abstract:
Means for predicting treatment response in a subject having cancer are disclosed, where the predictions are based comparing the number and size of circulating cancer associated macrophage-like cells (CMLS) and circulating tumor cells (CTCs) found in biological samples at baseline and after induction of therapy, such as blood, from the subject.
Abstract:
A microfilter having a hydrophilic surface and suited for size-based capture and analysis of cells, such as circulating cancer cells, from whole blood and other human fluids is disclosed. The filter material is photo-definable, allowing the formation of precision pores by UV lithography. Exemplary embodiments provide a device that combines a microfilter with 3D nanotopography in culture scaffolds that mimic the 3D in vivo environment to better facilitate growth of captured cells.
Abstract:
Means for predicting overall survival (OS) and progression free survival (PFS) of subjects having cancer are disclosed, where the predictions are based on the number arid size of circulating cancer associated macrophage-like cells (CAMLs) found in a biological sample, such as blood, from the subject.
