The present invention relates to novel domain exchanged, bivalent, bispecific antibodies, their manufacture and use.

The invention provides a thick coating material capable of purifying air and a preparation method thereof, belonging to the building material field. An internal wall coating decorative material comprises 5 to 40 weight portions of a porous absorbing material and 10 to 40 weight portions of a composite photocatalysis material in every 100 weight portion of the paint. In the preparation method, the coating material, is formed by compounding a mineral material with the nanometer photocatalysis material to obtain a high activity purifying material, matching the high activity purifying material with other nanometer materials and the porous absorbing material, and then adding an inorganic filling material, a skeletal material and other addition agents, can remove harmful gases such as formaldehyde and toluol in air and has the environmental protection function. The paint has good effect for removing formaldehyde, is effective continuously, has certain thickness when the coating layer is used, has simple construction, and beautiful and elegant patterns, is well-bedded, is strong in the three-dimension effect and has good decorative effect.

A catalyst has a base catalyst layer containing platinum and barium as precious metal supported by alumina and an over catalyst layer containing platinum and rhodium as precious metal supported by zeolitr. The platinum and rhodium in the over catalyst layer activate NOx and HC so as to make them more reactive in terms of energy, and the barium in the base catalyst layer makes the platinum be more dispersive in the base catalyst layer. Under the existence of dispersive platinum, NOx in exhaust gas is decomposed and purified by reaction with reactive NO2 and partially oxidized HC generated in the over catalyst layer.

In certain aspects, the present invention provides compositions and methods for increasing red blood cell and/or hemoglobin levels in vertebrates, including rodents and primates, and particularly in humans.

A method of assay for target polynucleotides includes steps of isolating target polynucleotides from extraneous non-target polynucleotides, debris, and impurities and amplifying the target polynucleotide.

The present invention relates to an integrated closed loop system for aquaculture in at least one culturing tank and using continuous bioreactor technology for the biological treatment and removal of organic material, nitrogen and phosphorous, comprising: an integrated, partially or wholly closed loop system for waste water treatment, where the water contains nitrogen containing compounds and/or substances, comprising at least one production unit of such nitrogen containing compounds and/or substances and using continuous bioreactor technology for the biological treatment and removal of organic matter, nitrogen and phosphorous from the said water at continuous flow, comprising: a) at least one suspended carrier bioreactor for bacterial growth under anoxic conditions to cause anaerobic denitrification, with one or several compartments, preceding b) at least one suspended-carrier bioreactor for bacterial growth under oxic conditions to cause aerobic nitrification, c) the denitrification taking place after the production unit, and d) the nitrification taking place prior to the production unit in a by-pass mode as part of the continuous flow.

In certain aspects, the present invention provides compositions and methods for treating or preventing breast cancer in humans.

In certain aspects, the present invention provides compositions and methods for promoting bone growth and increasing bone density, as well as for the treatment of multiple myeloma.

Novel cell surface molecules recognized by monoclonal antibodies against a cell surface molecule of lymphocytic cells that play an important role in autoimmune diseases and allergic diseases have been isolated, identified, and analyzed for their functions. The cell surface molecules are expressed specifically in thymocytes, lymphocytes activated by ConA-stimulation, and peripheral blood lymphocytes, and induce cell adhesion. Antibodies against the cell surface molecules significantly ameliorate pathological conditions of autoimmune diseases and allergic diseases.

The invention pertains to the technical field of fume purification. The provided functional filter felt for eliminating harmful constituents of fume can realize the desulfurization or denitration of fume when removing dust; the filter felt is made from fiber materials and a functional catalyst in a compound manner; when purifying the harmful constituents of fume, the filter felt filters the dusts in the fume with nonwoven fabrics made from high temperature-resistant fiber material and carries out a catalytic reaction to eliminate nitrogen oxides (NOX) and/or sulfur oxides (SOX) through the functional catalyst contained in the filter felt. The provided filter felt is applicable to fume dedusting devices, fume desulfurization devices and fume denitration devices in power plants, metallurgical plants and chemical plants, in particular to the manufacturing of bag type fume filter. Compared with the prior art, the invention simplifies the fume purifying processes, improves processing efficiency, effectively saves the investment and reduces operational expenses, thus being suitable for the modification of the existing fume dedusting device.

In certain aspects, the present invention provides compositions and methods for increasing red blood cell and/or hemoglobin levels in vertebrates, including rodents and primates, and particularly in humans.

A cell surface molecule that is expressed specifically in thymocytes, lymphocytes activated by ConA-stimulation, and peripheral blood lymphocytes. This molecule is involved in signal transmission of the secondary signal (costimulatory signal) essential for the activation of lymphocytes such as T cells and regulates functions of activated lymphocytes such as activated T cells. Disclosed are an antibody or a portion thereof, which binds to a polypeptide of the cell surface molecule, a polypeptide fragment thereof, or a fusion polypeptide comprising the fragment; a cell secreting the antibody or its portion; a pharmaceutical composition comprising the antibody; and methods of using the compositions for therapeutic, diagnostic and/or experimental purpose.
