(Wichita State University. Graduate School., 2008-04-25)In the past, electronic and magnetic materials have been atom based materials made up of metals or metal-oxides. Functionally,these atom based materials are extremely efficient, however, they are very expensive to synthesize, ... -
Recent advances in the discovery of norovirus therapeutics
(American Chemical Society, 2015-12-24)Noroviruses are members of the family Caliciviridae. Norovirus infections are a global health burden that impacts >20 million individuals annually in the U.S. alone. Noroviruses are associated with high morbidity among ... -
Recent developments in the design of mechanism-based and alternate substrate inhibitors of serine proteases
(Bentham Science, 2004-01-01)A wide range of human diseases are associated with the aberrant activity of mammalian, viral, bacterial or parasitic proteases. These include members of all four classes of proteases, namely, serine, cysteine, aspartic and ... -
Recommendations for reporting ion mobility mass spectrometry measurements
(Wiley, 2019-03-07)Here we present a guide to ion mobility mass spectrometry experiments, which covers both linear and nonlinear methods: what is measured, how the measurements are done, and how to report the results, including the uncertainties ... -
Reduction of dopamine beta-monooxygenase. A unified model for apparent negative cooperativity and fumarate activation
(American Society for Biochemistry and Molecular Biology, 1996-10-18)The interactions of reductants with dopamine beta-monooxygenase (DbetaM) were examined using two novel classes of reductants. The steady-state kinetics of the previously characterized DbetaM reductant, N,N-dimethyl-1,4-p ... -
The reduction of membrane-bound dopamine beta-monooxygenase in resealed chromaffin granule ghosts. Is intragranular ascorbic acid a mediator for extragranular reducing equivalents?
(American Society for Biochemistry and Molecular Biology, 1995-11-17)The role of internal and external reductants in the dopamine beta-monooxygenase (D beta M)-catalyzed conversion of dopamine to norepinephrine has been investigated in resealed chromaffin granule ghosts. The rate of ... -
Repurposing an inhibitor of ribosomal biogenesis with broad anti-fungal activity
(Nature Publishing Group, 2017-12-05)The lack of new antifungal compounds with unique mechanisms of action is a concern for therapeutic management of patients. To identify inhibitors against human pathogenic fungi, we screened similar to 3000 compounds provided ... -
Results compared for tricyclic antidepressants as assayed by liquid chromatography and enzyme immunoassay
(P.B. Hoeber, 1988-11-01)The tricyclic antidepressants amitriptyline, nortriptyline, imipramine, and desipramine in serum of patients taking one of the drugs were quantified in two laboratories by high-performance liquid chromatography (HPLC) and ... -
Reversal of the progression of fatal coronavirus infection in cats by a broad-spectrum coronavirus protease inhibitor
(Public Library of Science Pathogens, 2016-03-30)Coronaviruses infect animals and humans causing a wide range of diseases. The diversity of coronaviruses in many mammalian species is contributed by relatively high mutation and recombination rates during replication. This ... -
Review -- Two different multiple photosynthetic reaction centers using either zinc porphyrinic oligopeptide-fulleropyrrolidine or free-base porphyrinic polypeptide-Li+@C60supramolecular complexes
(Institute of Physics Publishing, 2020-08-10)An overview of two successful examples of photosynthetic reaction center models combined with light-capturing antenna chromophores is presented. In the first example, supramolecular complexes are formed between flexible ... -
Revisiting thiophosphate $Pb_3P_2S_8$: A multifunctional material combining a nonlinear optical response and photocurrent response
