26 Blumenthal, Donald K.In vivo evaluation of the delivery and efficacy of a sirolimus-laden polymer gel for inhibition of hyperplasia in a porcine model of arteriovenous hemodialysis graft stenosisSynthetic arteriovenous (AV) hemodialysis grafts are plagued by hyperplasia resulting in occlusion and graft failure yet there are no clinically available preventative treatments. Here the delivery and degradation of a sirolimus-laden polymer gel were monitored in vivo by magnetic resonance imaging ...2012-01-01

28 Poulter, Charles DaleIsopentenyl diphosphate:dimethylallyl diphosphate isomerase. An improved purification of the enzyme and isolation of the gene from Saccharomyces cerevisiae.Isopentenyl diphosphate:dimethylallyl diphosphate isomerase (IPP isomerase) is an enzyme in the isoprenoid biosynthetic pathway which catalyzes the interconversion of the primary five-carbon homoallylic and allylic diphosphate building blocks. We report a substantially improved procedure for purific...Amino Acid Sequence; Base Sequence; Chromatography, Gel; Chromatography, Ion Exchange1989-11-15
29 Asche, Carl V.Management of community-acquired respiratory tract infections in an era of increasing antibiotic resistance.Community-acquired respiratory tract infections (RTIs) are prevalent conditions in U.S. and represent a major burden in health care. This article provides an overview of empirical antibiotic treatment options for patients with community-acquired RYIs, including newer classes of agents, such as the r...Costs and Cost Analysis2006-02-01
30 Bernstein, Paul S.; Gellermann, WernerNonmydriatic fluorescence-based quantitative imaging of human macular pigment distributions.We have developed a CCD-camera-based nonmydriatic instrument that detects fluorescence from retinal lipofuscin chromophores ("autofluorescence") as a means to indirectly quantify and spatially image the distribution of macular pigment (MP). The lipofuscin fluorescence intensity is reduced at all ret...Cytology; Sensitivity and Specificity2006-10
31 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 Kinases1978-01-25
32 Baehr, Wolfgang; Prestwich, Glenn D.Photoreceptor cGMP phosphodiesterase delta subunit (PDEdelta) functions as a prenyl-binding proteinBovine PDEdelta was originally copurified with rod cGMP phosphodiesterase (PDE) and shown to interact with prenylated, carboxymethylated C-terminal Cys residues. Other studies showed that PDEdelta can interact with several small GTPases including Rab13, Ras, Rap, and Rho6, all of which are prenylate...Fluorescence Resonance Energy Transfer; GTP Phosphohydrolases; Immunohistochemistry2004
33 Poulter, Charles DalePrenyltransferase. Kinetic studies of the 1'-4 coupling reaction with avian liver enzyme.Prenyltransferase catalyzes the sequential, irreversible 1'-4 condensation of isopentenyl-PP with dimethylallyl-PP and geranyl-PP to yield farnesyl-PP. A kinetic study shows substrate inhibition by isopentenyl-PP at concentrations above 0.7 microM when the concentration of geranyl-PP is 1.0 microM o...Birds; Kinetics; Structure-Activity Relationship; Substrate Specificity1979-10-10
34 Gussin, Gary N.; Capecchi, Mario R.Protein synthesis directed by DNA phage messengers.Even through the amino acids corresponding to most of the 64 nucleotide triplets are now known, several important aspects of the genetic code are not yet fully understood. In particular we need more knowledge about the "punctuation marks" of the code-for example, the signals necessary for the initia...Carbon Isotopes; Escherichia coli; Genetic Code; Methionine1967-09-01
35 Blumenthal, Donald K.Rabbit skeletal muscle myosin light chain kinase. The calmodulin binding domain as a potential active site-directed inhibitory domain.A synthetic peptide modeled after the calmodulin (CaM)-binding domain of rabbit skeletal muscle myosin light chain kinase, Lys-Arg-Arg-Trp-Lys5-Lys-Asn-Phe-Ile-Ala10-Val-Ser-Ala-Ala-+ ++Asn15-Arg-Phe-Glycyl amide (M5), inhibited the CaM-independent chymotryptic fragment of the enzyme, C35 (Edelman, ...Synthetic Peptide1987-09-05
36 Blumenthal, Donald K.Ranolazine: a new antianginal agent with a novel mechanism of actionThis animation (with audio) illustrates the mechanism of action of ranolazine (RANEXA), a novel antianginal drug that inhibits the late sodium current (late I Na) in cardiac myocytes. The animation first describes how the late sodium current can contribute to symptoms of myocardial ischemia by causi...Angina; Myocardial Ischemia, Acute Coronary Syndrome; Voltage-Gated Sodium Channel, Late Sodium Current; Sodium-Calcium Exchanger; Calcium Overload; Ranolazine2006-09-19
37 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; Zeaxanthin2006-02-01

41 Digre, Kathleen B.; Warner, Judith E. A.; Bernstein, Paul S.; Alder, Stephen C.Vitamin A in the cerebrospinal fluid of patients with and without idiopathic intracranial hypertensionWe quantified vitamin A in the cerebrospinal fluid of patients with idiopathic intracranial hypertension, elevated intracranial pressure of other causes and normal intracranial pressure. Vitamin A could be detected by high-pressure liquid chromatography in most of the specimens. There was a signific...Chromatography, High Pressure Liquid; Headache2002-11
