Abstract: Biodegradable polymer networks are provided which are useful in a variety of dental and orthopedic applications. The biodegradable polymer networks can be formed in one embodiment by polymerizing anhydride prepolymers including crosslinkable groups, such as unsaturated moieties. The anhydride prepolymers can be crosslinked, for example in a photopolymerization reaction by irradiation of the prepolymer with light in the presence of a free radical initiator. Suitable anhydride prepolymers include dianhydrides of a dicarboxylic acid and a carboxylic acid molecule comprising a crosslinkable group. For example, methacrylic acid dianhydrides of monomers or oligomers of a diacid such as sebacic acid or 1,3-bis(p-carboxyphenoxy)-hexane can be used. The anhydride prepolymers can be applied in vivo to a site where an orthopedic implant is needed, and then may be crosslinked, for example, by irradiation with U.V. light, to form a biodegradable implant such as a rods, pin or plate.

Abstract: An organic electroluminescent element ("organic EL element") capable of emitting light with high luminance by driving at a low voltage, and inhibiting deterioration in organic layers is provided. A surface treatment of an indiumtin oxide (ITO) transparent electrode with a titanate coupling agent containing phosphorus in the side chain thereof improves adhesion between the ITO transparent electrode and an organic hole transport layer. As a result, it is possible to increase the efficiency of injection of holes, improve low-voltage driving and luminance, and prevent deterioration in the organic layers.

Abstract: A value-added composition of matter containing plant matter from transgenic alfalfa which expresses exogenous phytase activity is disclosed. The phytase activity is a gene product of an exogenous gene encoding for phytase which has been stably incorporated into the genome of alfalfa plants. The transgenic alfalfa expresses phytase activity in nutritionally-significant amounts, thereby enabling its use in animal feeds to eliminate the need for phosphorous supplementation of livestock, poultry, and fish feed rations.

Abstract: The present application relates to an extruded cosmetic composition, provided in the form of a soft paste, comprising, in a fatty phase, at least one compound having a high melting temperature.The invention also relates to a process for preparing the composition by extrusion.
Abstract: Fine metallic particles-containing fibers with various fine metallic particles therein, which have fiber properties to such degree that they can be processed and worked, and which can exhibit various functions of the fine metallic particles, such as antibacterial deodorizing and electroconductive properties are provided, as well as a method for producing the same.
Abstract: A carrier web having at least one surface that is multiple, sequentially embossed, wherein depressions created from the prior embossing patterns(s) are preserved during the subsequent embossing pattern(s) even though the subsequent embossing pattern(s) are superimposed on the depressions from the prior embossing pattern(s). The patterns of embossing can be Euclidean or fractal created from machine tools produced using microreplication and other techniques. The carrier webs are useful for release liners for pressure sensitive adhesives and a number of other industrial and consumer applications.

Abstract: A method and apparatus for applying a material to a substrate. A material application station includes a shutter assembly having at least one horizontally extending blade which is rapidly displaceable from a closed configuration in which an outlet path of the shutter assembly is obstructed to an open configuration in which the outlet path is open. While the blade of the shutter assembly is in the closed configuration, a coating material is applied to a first predetermined area on an upper surface of the shutter assembly. A substrate is located beneath the shutter assembly in the outlet path. The blade of the shutter assembly is rapidly opened so that the coating material falls onto the substrate over a second predetermined area on an upper surface of the substrate. The second predetermined area is substantially equal to the first predetermined area. The resulting deposit is of a controlled diameter.
Abstract: The present invention provides a non-infectious immunotherapeutic containing retroviral particles devoid of outer envelope proteins or containing selected antigens isolated from a retrovirus. There is also provided a vaccine effective against HIV. In one aspect, the immunogen is useful for immunizing an individual previously infected by a retrovirus including HIV, so as to induce immunoprotective factors protective against progression of the infection. In another aspect, the vaccine is useful for vaccinating an individual not previously infected with HIV in order to prevent subsequently acquired infection. In another aspect, there is provided a method of rendering a viral immunogen non-infectious. The immunogen may also be used to produce is antibodies for passive immunotherapy, alone or in conjunction with active immunotherapy, in individuals infected with a retrovirus, including HIV, preferably those individuals exhibiting low levels of antibodies to retroviral gene products other than the outer envelope.
Abstract: Vitaminized air fresheners and room deodorizers are disclosed which permit occupants to directly receive and enjoy the benefits of vitamins with little or no effort intra-nasally.

Abstract: A novel surface exposed protein of Haemophilus influenzae or related Haemophilus species is described. The protein named protein D is an Ig receptor for human IgD and has an apparent molecular weight of 42,000. Protein D can be detected in all of 116 encapsulated and non-encapsulated isolates of H. influenzae studied. The protein from all strains shows in addition to the same apparent molecular weight immunogenic similarities since protein D from all strains interacts with three different mouse monoclonal antibodies and monoclonal human IgD. A method for purification of protein D is described. Cloning of the protein D gene from H. influenzae in E. coli is described as well as the nucleotide sequence and the deduced amino acid sequence.
Abstract: In a plasma processing method, a substrate is processed by placing the substrate on an electrode in a vacuum chamber, introducing a gas into the vacuum chamber while discharging gas from inside vacuum chamber, applying a high frequency voltage to a spiral discharge coil while keeping the vacuum chamber internally at a pressure to generate a plasma inside the vacuum chamber. At least one of the control parameters of gas type, gas flow rate, pressure, magnitudes of high frequency powers applied to the coil and the electrode, and their high frequency power frequencies is varied while the substrate is processed. The method includes a step of allowing a plasma density in-plane distribution to be controlled in accordance with the timing of varying any of the control parameters.
