摘要:
The present invention is directed to an α thio-containing compound that is capable of inhibiting the enzyme, membrane aminopeptidase P (mAPP or APP), whose natural substrate is bradykinin. The compound is useful as a pharmaceutical agent because by inhibiting bradykinin degradation, the compound allows bradykinin to exert its beneficial effects on the cardiovascular system, to improve renal function, and to improve glucose tolerance and insulin-sensitivity. The present invention is also directed to a pharmaceutical composition comprising the mAPP inhibitor of the present invention and a pharmaceutically acceptable carrier. In another aspect, the present invention is directed to a method of inhibiting bradykinin degradation in a mammalian patient, preferably human, in need of treatment comprising administering to the patient a therapeutically effective amount of an α thio-containing compound of the present invention. The method of the present invention also contemplates the further step of administering to the mammalian patient in need of treatment a therapeutically effective amount of an inhibitor of angiotensin converting enzyme (ACE).

Disclosed are a foamable resin composition which comprises a copolymer with a weight-average molecular weight of 150,000-350,000 produced by copolymerization of a monomer mixture of 55-85% by weight of styrene and 45-15% by weight of a methacrylic acid ester represented by general formula (I)CH.sub.2 .dbd.C(CH.sub.3)COOR (I)(wherein R represents a C.sub.1-4 alkyl group) and, having impregnated therein, 10% by weight or less of a foaming agent relative to said monomer mixture, a thermoplastic foamable pattern which is constituted by heating, foaming and molding of a foamable resin composition as claimed in claim 1, a metal casting manufacturing method which comprises a stage wherein a thermoplastic foamable pattern as claimed in claim 9 is especially surrounded by refractory material and a stage wherein molten metal is poured into said pattern in order to eliminate said pattern and, as the result of solidification of said metal, form a casting as a reproduction of said pattern, and a metal casting manufacturing method which comprises a stage wherein a thermoplastic foamable pattern as claimed in claim 9 is especially surrounded by refractory material, a stage wherein said pattern is eliminated to form a space, a stage wherein molten metal is poured into said space and a stage wherein a casting is formed as a reproduction of said pattern by solidification of said metal.
摘要:
Vermicular graphite cast iron is produced by adding to molten iron simultaneously up to 0.3% by weight of the iron of one or more rare earth metals and in excess of 0.2% by weight of the iron of calcium the quantity of rare earth metal being within the range of 2 to 8 times the sulphur content of the molten iron.The rare earth may be added for example as cerium, mischmetall or as rare earth silicide. The calcium may be added for example as calcium metal or as calcium silicide or a nickel-calcium alloy. An alloy containing both rare earth and calcium, such as a calcium-cerium-silicon alloy, or a composition containing rare earth, calcium and a fluxing agent may also be used.
摘要:
In an iron molding process and in a mold for carrying out the process, in which the mold is at least locally coated with tellurium or bismuth to promote the production of a white iron structure there is included in the coating a mineral substance such as a clay containing water which is loosely chemically combined, or a substance containing hydroxyl groups, the water or each hydroxyl group being chemically combined tightly enough so that it withstands the heat involved in drying of the mold but is liberated on contact with the molten iron.

A cord holding device and method of use. An embodiment of the device includes a sheet of material having a turned end. The turned end is selectively positionable between a closed orientation and an open orientation. In the open orientation, an opening is formed between the turned end and the sheet to allow for the cord to be inserted within an interior section. In the closed orientation, the turned end wraps around the cord to retain it within the device. A method of using the device comprises mounting the device to a position to receive the cord. A holding section is unturned an amount to allow for the cord to be inserted within the interior section of the holding section. After cord insertion, the holding section re-turns and wraps around the cord.
摘要:
A rod is coupled to a frame to hold a wire reel that is to be loaded onto it. A roller is coupled to the frame so that its radial surface stays in contact with a radial surface of a spool wall of the loaded reel, as the loaded reel rotates. Other embodiments are also described and claimed.
