摘要:
Therapeutically-active and pharmacologically-acceptable 1-amido-5-cyano-4(1H)-pyrimidinones and their pharmaceutically-acceptable acid addition salts inhibit xanthineoxidase and are useful as the active ingredient in medicaments for the treatment of gout. Such pyrimidinones are prepared by treating 2-(acyl) hydrazonomethyl-3-chloro or hydroxy-4-aza-2,4-pentadienenitriles with acid.
摘要:
The present invention is directed to a device which supports a user's spine while the user is in a forward bent position. The device includes a padded rest on which the user can lean while working in a forward bent position, and support structure enabling at least three of lateral adjustment of the rest along the projected perimeter of the work area, adjustment of the rest across the projected perimeter, height adjustment of the rest, and angular orientation of the rest. Since the user leans against the rest, the stresses otherwise normally experienced in the lower, middle and upper back are substantially attenuated. Attenuating such stress attenuates the pain experienced by the user as well as potentially extending his or her productive life.

Aryl-substituted piperazinyl-alkylamino-uracils, the corresponding uracil ethers and uracil-thioethers and their pharmaceutically acceptable salts such as the hydrochloride, and method for the preparation of these compounds. The novel compounds are useful for lowering the blood pressure, causing an analgesic, a sedative or antihistiminic effect in mammalians.
摘要:
A recreational accessory and corresponding mounting assembly is disclosed which is adapted and configured for use in combination with a substrate, such as a pier, dock, deck, porch, staircase, etc. The mounting assembly is secured to the substrate and the recreational accessory is removably attached to the mounting assembly. In the complete assemblage, the mounting assembly is optionally cantilevered outwardly beyond the perimeter of the substrate. Accordingly, the recreational accessory does not occupy any surface area of the substrate.
摘要:
The present invention is directed to a device that supports an individual's spine while the individual is in a forward bent position. The device includes a padded rest on which an individual could lean while working in a forward bent position and brackets for adjusting the angle, height, and position of the device. Since the individual leans against the rest, the stresses experienced in the lower, middle and upper back are substantially decreased. Reducing such stress decreases the pain experienced by the individual as well as extends his or her productive life.
摘要:
An intravascular catheter such as a guiding catheter of composite construction having a nontraumatic distal tip comprising a proximal elastomeric tubular element and a distal elastomeric tubular element formed of softer material that the proximal section. The proximal tubular section of the distal tip preferably has a radiopaque material incorporated therein to enable the distal tip to be fluoroscopically observable when in place within a patient. The shaft of the catheter, which exhibits excellent torquability and pushability, is formed with a very thin wall. The catheter shaft includes an inner tubular member of braided polymeric fibrous strands impregnated with a thermoset polyurethane and having an outer jacket or coating of thermoplastic polyurethane secured to the braided tubular member. In some embodiments it is preferred to include a lubricous liner within the braided tubular member.
摘要:
Substituted hydrazino- and pyrazolo-aldopentoses and aldohexoses, which are useful as intermediates for preparing compounds, as compounds which lower the uric acid level in the blood, and as bactericides, are provided. The substituted hydrazino compounds also enter into chemical reactions which are not possible with their unsubstituted counterparts.
