摘要:
Compositions and processes featuring, in one aspect, a process of purifying a protein diagnostic for atherosclerosis comprising separating out of primate and human atherosclerotic tissue a Gla-containing protein of molecular weight of about 80,000.
摘要:
Copolymers having improved machining and water resistant properties are produced using a monomer containing an adduct protecting group, particularly an alkyl boronic acid adduct, of glyceryl acrylate or glyceryl methacrylate, in combination with an alkyl acrylate or methacrylate, and optionally a glycidyl acrylate or methacrylate. After machining and shaping, the adduct is removed to provide a hydrogel useful as a contact lens material.
摘要:
The invention provides new hydrogel forming materials comprising synthetic, hydrophilic, aqueous-insoluble polymer networks formed by copolymerization of a hydrophilic dihydroxyalkyl acrylate or methacrylate, a substantially water insoluble alkyl acrylate or methacrylate, one or more additional hydrophilic comonomers selected from the group of vinylic monomers, acrylates, and methacrylates, and a cross-linking agent. The hydrogels are preferably used for the formation of contact lenses, but may also be used for drug and pesticides delivery devices; dialysis, ultrafiltration and reverse osmosis membranes; implants in surgery and dentistry; and the like.
摘要:
The invention provides a method of treating hydrogels formed from the polymerization of monomers having reactive olefinic double bonds by contacting them with reactive thiol compounds. In a preferred embodiment where the hydrogel structure includes a cis-glycol containing unit, a suitable thiol is used in conjunction with a borate buffer. The present invention also provides materials that are treated with the above thiol compounds.

摘要:
PQQ and PQQ-generating compounds inhibit osteoclast cell formation and bone resorption, and those compounds can be used to treat medical conditions characterized by undesired bone resorption. PQQ-phosphonates that target osteoclasts at the bone-mineral interface are particularly useful in this regard.
摘要:
A method for resisting neurological damage caused by overstimulation of theMDA receptor of nerve cells by glutamate includes exposing the NMDA receptors to an oxidizing agent to thereby diminish overall activity of the receptors following activation by glutamate. The oxidizing agent preferably is a material selected from the group consisting of pyrroloquinoline quinone and topa hydantoin.

Process and apparatus for measuring glycosylated hemoglobin by assaying bound glyco groups in hemolysate featuring, in one aspect, appropriate oxidation of glycosylated hemoglobin and the rapid measurement of the resultant aldehydic compounds.
摘要:
Methods are disclosed for treating PQQ-responsive heavy metal toxicity which include the administration of PQQ to a patient in need thereof. The toxicity may be associated with such heavy metals as lead, indium and vanadium.
