Patent number: 5702955Abstract: The present invention is a method for the detection of hydrogen peroxide in biological fluids or an aqueous solution which involves contacting the solution with an oxidation-reduction indicator and a transition metal complex. The transition metal complex is either a creatinine coordinated with iron or a guanidine coordinated with iron.Type: GrantFiled: October 6, 1995Date of Patent: December 30, 1997Assignee: Bayer CorporationInventor: Michael Pugia

Patent number: 5700447Abstract: The in vivo oxidation of lipids and lipid-containing molecules has been discovered to be initiated by the concurrent reaction of such lipid materials with reducing sugars such as glucose, advanced glycosylation endproducts such as AGE-peptides, or a compound which forms advanced glycosylation endproducts, to form materials or particles known as AGE-lipids. AGE-lipids have been implicated in the aging process, the abnormal formation of lipofuscin and in various disease states such as diabetes and atherosclerosis. Diagnostic methods are contemplated, extending in utility from the detection of the onset and course of conditions in which variations in lipid oxidation, AGE-lipid levels, LDL levels, apolipoprotein levels, apolipoprotein receptor binding the like, may be measured, to drug discovery assays.Type: GrantFiled: October 7, 1994Date of Patent: December 23, 1997Assignee: The Picowder Institute for Medical ResearchInventors: Richard J. Bucala, Helen Vlassara, Anthony Cerami, Kevin J. Tracey

Patent number: 5685300Abstract: A method of noninvasive and in-vitro glucose and cholesterol concentration measurement employing nuclear magnetic resonance (NMR) spectroscopy is described. The measurement comprises a ratio formed by dividing the area of the resonance of the desired analyte, e.g., glucose or cholesterol, by the area of the water resonance in a spectrum of blood or tissue. In the in-vivo setting, the spectrum is obtained either in linkage with the pulsation of blood or by using a slice selection gradient such as that employed in the magnetic resonance imager. This measurement is then correlated to a traditional serum analyte concentration.Type: GrantFiled: March 10, 1995Date of Patent: November 11, 1997Inventor: J. Todd Kuenstner

Patent number: 5686250Abstract: Levuglandin (LG) derivatives are used as antigens for raising antibodies useful in diagnostic assays. The antibodies produced by LG-carrier protein adducts can be used to detect adducts of LGE.sub.2 with human low density lipoprotein (LDL). LGE.sub.2 -protein adduct immunoreactivity may be generated during in vitro free-radical oxidation of LDL. An enzyme-linked immunosorbent assay for detecting adducts of LGE.sub.2 with human LDL is also described.Type: GrantFiled: July 31, 1996Date of Patent: November 11, 1997Assignee: Case Western Reserve UniversityInventor: Robert G. Salomon
