Abstract:
Provided is a sustained release composition for sustained release of a pharmaceutical substance. The composition includes a biocompatible polymer that is highly amorphous and a pharmaceutical substance in a hydrophobic ion complex with an amphiphilic material. Also provided a compressed antisolvent method for manufacturing the composition, various product forms incorporating the composition and various uses for the composition.
Abstract:
Provided is a method for preparing a true, homogeneous solution of a pharmaceutical substance dissolved in an organic solvent in which the pharmaceutical substance is not normally soluble. Solubilization is obtained by forming a hydrophobic ion pair complex involving the pharmaceutical substance and an amphiphilic material. The resulting organic solution may be further processed to prepare pharmaceutical powders. A biodegradable polymer may be co-dissolved with the pharmaceutical substance and the amphiphilic material and may be incorporated into a pharmaceutical powder. A preferred method for preparing pharmaceutical powders is to subject the organic solution to gas antisolvent precipitation using a supercritical gas antisolvent such as carbon dioxide. Also provided is a method for making hollow particles having a fiber-like shape which would provide enhanced retention time in the stomach if ingested by a human or animal host. Further provided are novel biocompatible cationic surfactants and uses therefor, including the delivery, in vitro and in vivo, of nucleic acids into cells to transform the cells.
Abstract:
The present invention relates to stable HPV capsomeres which express at least one virus-neutralizing conformational epitope of a native HPV L1 protein which are substantially incapable of assembly into virus-like particles. These capsomeres, because of their smaller size, and immunogenic properties are well suited for use in HPV vaccines and as diagnostic agents. Moreover, because of their smaller size (relative to VLPs), these stable capsomeres may be easily purified and should result in HPV vaccines of enhanced homogeneity.
Abstract:
The present invention provides a method for growing atomic layer thin films on functionalized substrates at room temperature using catalyzed binary reaction sequence chemistry. Specifically, the atomic layer films are grown using two half-reactions. Catalysts are used to activate surface species in both half-reactions thereby enabling both half-reactions to be carried out at room temperature.
Abstract:
A programmable hologram generator comprises a layered structure of a pixelated VLSI chip, a reflective ferroelectric liquid crystal that is physically disposed on the VLSI chip, and a photorefractive crystal that is physically disposed on the liquid crystal. The VLSI chip is controlled by a computer wherein holograms are digitally stored. The reflective state of the individual pixel areas of the liquid crystal are controlled or selected by this computer control of the VLSI chip. A desired hologram is written into the photorefractive crystal by a reference beam that illuminates the photorefractive crystal, and by an illumination beam that is reflected from the selected pixels of the liquid crystal and thereafter interferes with the reference beam. The hologram that is written into the photorefractive crystal is a function of the control of the reflective state of the pixels of the liquid crystal, as this reflective state is in turn controlled by the pixels of the VLSI chip.
Abstract:
A condenser system for controlling vapor concentration contained in a flowing airstream is provided. The flowing airstream has an initial temperature upon entering the condenser system and a final temperature upon exiting the condenser system. The condenser system has a membrane member allowing mass transfer of the vapor therethrough with the airstream contacting the membrane member. A condensing member diffuses the vapor from the airstream through the membrane member. An insulating layer is positioned between the membrane member and the condensing member with the insulating layer inhibiting heat transfer between the flowing airstream and the condensing member wherein the final temperature of the airstream is substantially equal to the initial temperature of the airstream.

Abstract:
This invention provides a method and apparatus for analyzing the propagation of optical fields between arbitrarily oriented planes using full scalar diffraction theory. One aspect of the invention allows propagation between tilted planes. A second aspect allows propagation between offset planes. To analyze the propagation of an input optical field from a first plane to a second plane, the input field in the spatial domain is Fourier transformed to obtain the plane wave distribution in the spatial frequency domain. Within the spatial frequency domain the field is propagated from the first plane to the second plane by first multiplying the plane wave distribution by the spatial frequency domain phase accumulation between the first and second planes, and then converting the plane wave distribution from the coordinate system of the first plane to that of the second plane. Finally, the propagated plane wave distribution is inverse Fourier transformed to obtain the propagated optical field. This propagation sequence forms the building block for a numerical method to analyze optical systems using full scalar diffraction theory. To analyze optical systems, the input field is propagated from the plane of the source to the plane of the first optical element and the propagated optical field is multiplied by the transmittance function of the optical element. This invention further includes tolerance analysis of each parameter that affects the image quality and coupling efficiency of the optical system.
