Method for modulating responsiveness to corticosteroids in a subject are provided. In the method of the invention, an agent which antagonizes a factor that regulates production of IFN-.gamma. in the subject is administered to the subject in combination with a corticosteroid such that responsiveness of the subject to the corticosteroid is modulated as compared to when a corticosteroid alone is administered to the subject. In one embodiment, the agent is an interferon-.gamma. inducing factor (IGIF) antagonist. In another embodiment, the agent is an interleukin-12 (IL-12) antagonist. In a preferred embodiment, the agent is an inhibitor of a caspase family protease, preferably an ICE inhibitor. In another preferred embodiment, the agent is an anti-IL-12 monoclonal antibody. Other preferred agents include phosphodiesterase IV inhibitors and beta-2 agonists. The methods of the invention can be used in the treatment of a variety of inflammatory and immunological diseases and disorders. Pharmaceutical compositions comprising an agent which antagonizes a factor that regulates production of IFN-.gamma. in a subject, a corticosteroid and a pharmaceutically acceptable carrier are also provided. A preferred composition comprises an ICE inhibitor, a corticosteroid and a pharmaceutically acceptable carrier.

Catalyst for complete oxidation of formaldehyde at room temperature

The invention provides a high selectivity catalyst used for catalyzing and completely oxidizing formaldehyde with low concentration at room temperature. The catalyst can catalyze formaldehyde completely so as to lead the formaldehyde to be converted into carbon dioxide and water at room temperature. In addition, the conversion rate of formaldehyde remains 100% within a long period of time, without complex auxiliary facilities such as light source, a heating oven and the like, and external conditions. The catalyst comprises three parts which are inorganic oxide carrier, noble metal component and auxiliary ingredient. Porous inorganic oxide carrier is one of cerium dioxide, zirconium dioxide, titanium dioxide, aluminium sesquioxide, tin dioxide, silicon dioxide, lanthanum sesquioxide, magnesium oxide and zinc oxide or the mixture thereof or composite oxide thereof, zeolite, sepiolite and porous carbon materials. The noble metal component of the catalyst is at least one of platinum, rhodium, palladium, gold and silver. The auxiliary ingredient is at least one of the alkali metals of lithium, sodium, kalium, rubidium and cesium. The loading of the noble metal component used in the catalyst of the invention is 0.1 to 10% according to weight converter of metal elements and the selective preference is 0.3 to 2%. The loading of the auxiliary ingredient is 0.2 to 30% according to weight converter of metal elements and the selective preference is 1 to 10%. When the loading of the auxiliary ingredient is lower than 0.2% or higher than 30%, the activity of the catalyst for catalyzing and oxidizing formaldehyde at room temperature is decreased remarkably.

Special biological fish-fertilizer for aquaculture and preparation method thereof

The invention discloses a special biological fish fertilizer and a preparation method for the fertilizer used in aquiculture; wherein, the biological fish fertilizer mainly comprises raw materials as follows: microbiological preparation, inorganic fertilizers, fermentation organics, micro-mineral amino acid chelate, mineral composites, and water quality improver. The preparation method for the special biological fish fertilizer in aquiculture comprises steps as follows: microbiological preparation is produced; fermentation organics is then produced, and the micro-mineral amino acid chelate is produced, eventually the finished products are made. The special biological fish fertilizer has the advantages of limiting the growth and reproduction of the harmful algae, promoting the large-scale growth and reproduction of the suitable food for fish, effectively improving the water quality and purifying the water environment, strengthening the fish immunity, reducing the diseases, reducing cost due to the small use level, convenient use, mild odor, no pollution to the water, and environment protection. By combining the modern bioengineering technique, low-temperature drying technique, spray-drying technique, and super-fine crushing techniques, the preparation method has the advantages of stable quality for the fish fertilizers and lower overall cost.

Chimeric viruses presenting non-native surface proteins and uses thereof

The present invention provides chimeric negative-stand RNA viruses that allow a subject, e.g., an avian, to be immunized against two infectious agents by using a single chimeric virus of the invention. In particular, the present invention provides chimeric influenza viruses engineered to express and incorporate into their virions a fusion protein comprising an ectodomain of a protein of an infectious agent and the transmembrane and cytoplasmic domain of an influenza virus protein. Such chimeric viruses induce an immune response against influenza virus and the infectious agent. The present invention also provides chimeric Newcastle Disease viruses (NDV) engineered to express and incorporate into their virions a fusion protein comprising the ectodomain of a protein of an infectious agent and the transmembrane and cytoplasmic domain of an NDV protein. Such chimeric viruses induce an immune response against NDV and the infectious agent.

Environment-friendly light heat-insulating material and manufacturing method thereof

The invention relates to an environment-friendly light heat-insulating material for fireproof doors and buildings, and a manufacturing method thereof. The manufacturing method is characterized by comprising the following steps of: pretreating plant hollow core bodies and/or flexible porous fillers by using a water glass adhesive; mixing with inorganic fire-resistant hollow particles; and performing mould pressing, shaping and drying to obtain the environment-friendly light heat-insulating material. The hollow core bodies and the flexible porous fillers are arranged multidirectionally; one layer of water glass adhesive is arranged at least on the surfaces of the hollow core bodies and the flexible porous fillers; and discontinuous holes are reserved between the hollow core bodies and/or the flexible porous fillers and the inorganic fire-resistant hollow particles. Preferably, the hollow core bodies are rice husks and straw sections; and the flexible porous fillers are foam and fibers. Renewable plant resources and recovered foam and fiber waste are adopted, so the environment-friendly light heat-insulating material is energy-saving and environment-friendly; and a large number of sealed holes are formed among the material particles through the penetration and coating of the modified water glass adhesive, and a heat-insulating hydrophobic corrosion-resistant multi-effect protective layer is provided, so the environment-friendly light heat-insulating material has good fireproof, heat-insulating and heat-preserving effects, high weather resistance, combined rigidity and toughness, low density and low cost.
