The prevalence and effects of age-related macular degeneration (AMD) and cataract are increasing dramatically as the proportion of elderly in our population continues to rise. A multivitamin-multimineral supplement with a combination of vitamin C, vitamin E, beta-carotene, and zinc (with cupric oxide) is recommended for AMD but not cataract. Weak support exists for multivitamins or other vitami...

Soils and decayed plant litter contain significant quantities of chlorinated aromatic polymers that have a natural but largely unknown origin. We used cupric oxide ligninolysis coupled with gas chromatography/mass spectrometry to show that Curvularia inaequalis, a widely distributed litter ascomycete, chlorinated the aromatic rings of lignin in wood that it was degrading. In aspen wood decayed ...

In order to expand the applicability of muon spin rotation, relaxation, and resonance ($\mu$SR) experiments with pulsed muons make effective use high-flux beam, we have developed a new experimental method ``transient $\mu$SR''. this method, $\mu$SR data for each pulse are tagged external parameters such as temperature magnetic field in real time, allowing sample environment be changed without i...

In a study of the mechanism of activation of the copper enzyme, ascorbic acid oxidase, it was observed that most compounds which activate this enzyme have the common property of forming complex compounds with cupric ion (l-3). Among these activating substances were ribonucleic acid,’ deoxyribonucleic acid, and certain of their constituents. These substances showed a surprisingly strong affinity...
