Askew, Eldon W.; Bernstein, Paul S. | Serum and macular responses to antioxidant supplementation verus a carotenoid-rich dietary intervention in the elderly. | The aim of this study was to observe responses of serum antioxidants, oxidative stress biomarkers, and macular carotenoid pigments to antioxidant supplements or dietary intervention in a single-masked, randomized, pilot clinical study of elderly subjects receiving antioxidant supplements or a dietar... | Macula; Serum Carotenoids; Zeaxanthin | 2006-02-01 |

Blumenthal, Donald K. | Phosphorylation of cardiac troponin by guanosine 3':5'-monophosphate-dependent protein kinase. | Homogeneous cGMP-dependent protein kinase catalyzes the rapid incorporation of phosphate, specifically into the inhibitory subunit of purified cardiac troponin with a maximal incorporation of 1 mol of phosphate/mol of troponin. When troponin was incubated in the presence of both cGMP- and cAMP-depen... | Protein Kinases | 1978-01-25 |

Blumenthal, Donald K. | Effects of deletions in the central helix of calmodulin on enzyme activation and peptide binding. | Using site-directed mutagenesis we have expressed in Escherichia coli three engineered calmodulins (CaM) containing deletions in the solvent-exposed region of the central helix. These are CaM delta 84, Glu-84 removed; CaM delta 83-84, Glu-83 and Glu-84 removed; and CaM delta 81-84, Ser-81 through Gl... | Drug Effects; Genetics; Metabolism | 1989-05-15 |

Frederick, Jeanne M.; Thulin, Craig; Bernstein, Paul S. | Identification and characterization of a Pi isoform of glutathione S-transferase (GSTP1) as a zeaxanthin-binding protein in the macula of the human eye | Uptake, metabolism, and stabilization of xanthophyll carotenoids in the retina are thought to be mediated by specific xanthophyll-binding proteins (XBPs). A membrane-associated XBP was purified from human macula using ion-exchange chromatography followed by gel-exclusion chromatography. Two-dimensio... | Circular Dichroism; Isoelectric Focusing; Macula Lutea; Xanthophylls | 2004 |

Hendee, Shonn P.; Faour, Fouad A.; Christensen, Douglas A.; Patrick, Baharah; Durney, Carl H.; Blumenthal, Donald K. | Effects of weak extremely low frequency magnetic fields on calcium/calmodulin interactions. | Mechanisms by which weak electromagnetic fields may affect biological systems are of current interest because of their potential health effects. Lednev has proposed an ion parametric resonance hypothesis (Lednev, 1991, Bioelectromagnetics, 12:71-75), which predicts that when the ac, frequency of a c... | Electromagnetic Fields; Calcium-binding Proteins; Lednev's Theory | 1996-06 |
