Stereochemical And Regiochemical Trends In The Selective Detection Of Saccharides, Shan Jiang, Jorge O. Escobedo, Kyu Kwang Kim, Onur Alptürk, George K. Samoei, Sayo O. Fakayode, Isiah M. Warner, Oleksandr Rusin, Robert M. Strongin Sep 2006

Stereochemical And Regiochemical Trends In The Selective Detection Of Saccharides, Shan Jiang, Jorge O. Escobedo, Kyu Kwang Kim, Onur Alptürk, George K. Samoei, Sayo O. Fakayode, Isiah M. Warner, Oleksandr Rusin, Robert M. Strongin

Faculty Publications

Several discreet sugar-boronate complexes exist in solution. This is due to the complex equilibria between isomeric species of even the simplest monosaccharides. In the current investigation, we determine the regio- and stereochemical features of the various equilibrating sugar isomers that induce signal transduction in boronic acid chemosensors such as 1 as well as 2 and 3. We present a unique example of a chemosensor (1) that is selective for ribose, adenosine, nucleotides, nucleosides, and congeners. As a result of this study, we are able to predict and achieve selective fluorescence and colorimetric responses to specific disaccharides as a consequence of …

Mesostructured Silica Chemically Doped With RuIi As A Superior Optical Oxygen Sensor, Bingfu Lei, Bin Li, Haoran Zhang, Shaozhe Lu, Zhuhong Zheng, Wenlian Li, Yue Wang

Faculty Publications

Novel oxygen sensors consisting of a [Ru(bpy)2phen]2+ (bpy: 2,2′-bipyridyl, phen: phenathroline) portion covalently grafted to a mesostructured silica-based network are prepared in situ via a sol-gel approach with the help of cetyltrimethylammonium-bromide (CTAB) surfactant. 1,10-Phenanthroline covalently grafted to 3-(triethoxysilyl)propyl isocyanate is used as not only the sol-gel precursor but also as the second ligand of the Ru(bpy)2d2 · 2H2O complex to prepare the sol-gel-derived mesostructured silicates for an oxygen sensor. For comparison purposes, the oxygen sensors in which [Ru(bpy)2phen]Q2 is conventionally physically incorporated into the matrix are also prepared. Elemental analysis, NMR, Fourier transform IR, UV-vis electronic absorption, luminescence-intensity quenching …

“Arrogance Cloaked As Humility” And The Majoritarian First Amendment: The Free Speech Legacy Of Chief Justice William H. Rehnquist, Edward L. Carter, Brad Clark Sep 2006

“Arrogance Cloaked As Humility” And The Majoritarian First Amendment: The Free Speech Legacy Of Chief Justice William H. Rehnquist, Edward L. Carter, Brad Clark

Faculty Publications

In his 19 years as Chief Justice of theUnited States, William H. Rehnquist voted in favor of the individual expression interest asserted in approximately one-fifth of the Speech Clause cases heard by the Supreme Court. Meanwhile, he opposed protecting those constitutional interests in approximately two-thirds of the speech cases during that time. (His votes evidenced both speech-protective and non-protective elements just more than 10 percent of the time). This manuscript analyzes the Rehnquist jurisprudence in comparison with that of his two immediate predecessors as Chief, Warren Burger and Earl Warren. Rehnquist’s deference to government, reliance on history and formalist categorization …

Post-Thaw Amendment Of Cryopreserved Sperm For Use In Artificial Insemination Of A Viviparous Fish, The Green Swordtail Xiphophorus Helleri, Qiaoxiang Dong, Changjiang Huang, Terrence R. Tiersch Sep 2006

Post-Thaw Amendment Of Cryopreserved Sperm For Use In Artificial Insemination Of A Viviparous Fish, The Green Swordtail Xiphophorus Helleri, Qiaoxiang Dong, Changjiang Huang, Terrence R. Tiersch

Faculty Publications

Sperm cryopreservation protocols have been developed for live-bearers such as the green swordtail Xiphophorus helleri and the platyfish Xiphophorus couchianus. Despite the high post-thaw motility (∼ 75%) obtained in both species, the requirements of sperm storage within the female reproductive tract coupled with the process of internal fertilization place functional demands upon cryopreserved sperm samples far beyond those of oviparous species. The purpose of this study was to facilitate the artificial insemination process with cryopreserved sperm of X. helleri through evaluation of parameters related to sperm quality after thawing. Specifically, this study evaluated the effects on motility for fresh and …

Two Glucose-Sensing Pathways Converge On Rgt1 To Regulate Expression Of Glucose Transporter Genes In Saccharomyces Cerevisiae, Jeong-Ho Kim, Mark Johnston Sep 2006

Two Glucose-Sensing Pathways Converge On Rgt1 To Regulate Expression Of Glucose Transporter Genes In Saccharomyces Cerevisiae, Jeong-Ho Kim, Mark Johnston

Faculty Publications

The yeast Saccharomyces cerevisiae deploys two different types of glucose sensors on its cell surface that operate in distinct glucose signaling pathways: the glucose transporter-like Snf3 and Rgt2 proteins and the Gpr1 receptor that is coupled to Gpa2, a G-protein α subunit. The ultimate target of the Snf3/Rgt2 pathway is Rgt1, a transcription factor that regulates expression of HXT genes encoding glucose transporters. We have found that the cAMP-dependent protein kinase A (PKA), which is activated by the Gpr1/Gpa2 glucose-sensing pathway and by a glucose-sensing pathway that works through Ras1 and Ras2, catalyzes phosphorylation of Rgt1 and regulates its function. …

Introduction: Self-Organization In Nonequilibrium Chemical Systems, Irving R. Epstein, John A. Pojman, Oliver Steinbock Sep 2006

Introduction: Self-Organization In Nonequilibrium Chemical Systems, Irving R. Epstein, John A. Pojman, Oliver Steinbock

Faculty Publications

The field of self-organization in nonequilibrium chemical systems comprises the study of dynamical phenomena in chemically reacting systems far from equilibrium. Systematic exploration of this area began with investigations of the temporal behavior of the Belousov-Zhabotinsky oscillating reaction, discovered accidentally in the former Soviet Union in the 1950s. The field soon advanced into chemical waves in excitable media and propagating fronts. With the systematic design of oscillating reactions in the 1980s and the discovery of Turing patterns in the 1990s, the scope of these studies expanded dramatically. The articles in this Focus Issue provide an overview of the development and …

Religion And Family Relational Health: An Overview And Conceptual Model, Loren Marks Aug 2006

Religion And Family Relational Health: An Overview And Conceptual Model, Loren Marks

Faculty Publications

This paper presents a review of research addressing religion and family relational health. Strengths of the extant data include the correlation of three dimensions of religious experience (religious practices, religious beliefs, and religious community) with certain aspects of mother–child, father–child, and marital relationships and specific connections between the three dimensions of religious experience and family relationships are identified. Key weaknesses in the research at present include a paucity of research examining the hows, whys, and processes involved behind identified religion–family correlations and a lack of data on non-nuclear families, families of color, interfaith families, and non-Christian religions including Judaism and …

Exposure Of Neonates To Respiratory Syncytial Virus Is Critical In Determining Subsequent Airway Response In Adults, Dahui You, David Becnel, Kai Wang, Michael Ripple, Melissa Daly, Stephania A. Cormier Aug 2006

Exposure Of Neonates To Respiratory Syncytial Virus Is Critical In Determining Subsequent Airway Response In Adults, Dahui You, David Becnel, Kai Wang, Michael Ripple, Melissa Daly, Stephania A. Cormier

Faculty Publications

Background: Respiratory syncytial virus (RSV) is the most common cause of acute bronchiolitis in infants and the elderly. Furthermore, epidemiological data suggest that RSV infection during infancy is a potent trigger of subsequent wheeze and asthma development. However, the mechanism by which RSV contributes to asthma is complex and remains largely unknown. A recent study indicates that the age of initial RSV infection is a key factor in determining airway response to RSV rechallenge. We hypothesized that severe RSV infection during neonatal development significantly alters lung structure and the pulmonary immune micro-environment; and thus, neonatal RSV infection is crucial in …

Incorporating Policymaker Costs And Political Competition Into Rent-Seeking Games, R. Kenneth Godwin, Edward J. Lopez, Barry J. Seldon Jul 2006

Incorporating Policymaker Costs And Political Competition Into Rent-Seeking Games, R. Kenneth Godwin, Edward J. Lopez, Barry J. Seldon

Faculty Publications

We incorporate policymaker costs of supplying rents and variable intensities of competition among rent seekers into the standard rent-seeking game. By incorporating these aspects, the game has greater verisimilitude to the lobbying process. The first aspect captures the fact that in rent-seeking contests there is a positive probability that neither firm will obtain the rent. The second aspect captures the fact that firms seeking different rents still must compete for policymakers' resources. We find that lobbying expenditures, rent-seeking profits, and rent dissipation depend on the intensity of competition and the value of the rent relative to policymaker costs. For example, …

Eminent Domain Reform In Missouri: A Legislative Memoir, Dale A. Whitman Jul 2006

Eminent Domain Reform In Missouri: A Legislative Memoir, Dale A. Whitman

Faculty Publications

The Missouri General Assembly, like a number of other state legislatures, undertook to reform its statutes relating to eminent domain during the 2006 legislative session. This article is the story of that effort and an analysis of the result. I write from a personal perspective. I was fortunate to have been personally involved in many of the decisions that were made as the bill, House Bill 1944, made its was through the legislative process. This opportunity was, I think, fairly unusual for a law professor; in thirty-seven years of teaching property law, I had never previously been so closely engaged …

'Tis A Gift To Be Simple: A Model Reform Of The Federal Sentencing Guidelines, Frank O. Bowman Iii Jul 2006

'Tis A Gift To Be Simple: A Model Reform Of The Federal Sentencing Guidelines, Frank O. Bowman Iii

Faculty Publications

This essay introducing the June 2006 edition of the Federal Sentencing Reporter (Vol. 18, No. 5) describes two important contributions to the movement for real reform of the federal sentencing system. First, Professor Bowman summarizes the recommendations of the Constitution Project Sentencing Initiative (CPSI) report on federal sentencing. The CPSI report, reproduced in this Issue, cautions against any over-hasty legislative response to the Supreme Court's decision in United States v. Booker, suggests some near-term improvements to the existing federal sentencing system, and then sets out a framework for a reformed and markedly simplified federal sentencing regime. Second, Professor Bowman describes …

Reca And Rada Proteins Of Brucella Abortus Do Not Perform Overlapping Protective Dna Repair Functions Following Oxidative Burst, Christelle M. Roux, Natha J. Booth, Bryan H. Bellaire, Jason M. Gee, R. Martin Roop, Michael E. Kovach, Renée M. Tsolis, Philip H. Elzer, Don G. Ennis Jul 2006

Reca And Rada Proteins Of Brucella Abortus Do Not Perform Overlapping Protective Dna Repair Functions Following Oxidative Burst, Christelle M. Roux, Natha J. Booth, Bryan H. Bellaire, Jason M. Gee, R. Martin Roop, Michael E. Kovach, Renée M. Tsolis, Philip H. Elzer, Don G. Ennis

Faculty Publications

Very little is known about the role of DNA repair networks in Brucella abortus and its role in pathogenesis. We investigated the roles of RecA protein, DNA repair, and SOS regulation in B. abortus. While recA mutants in most bacterial species are hypersensitive to UV damage, surprisingly a B. abortus recA null mutant conferred only modest sensitivity. We considered the presence of a second RecA protein to account for this modest UV sensitivity. Analyses of the Brucella spp. genomes and our molecular studies documented the presence of only one recA gene, suggesting a RecA-independent repair process. Searches of the available …

Workplace Blogs And Workers' Privacy, Rafael Gely, Leonard Bierman Jul 2006

Workplace Blogs And Workers' Privacy, Rafael Gely, Leonard Bierman

Faculty Publications

In this article we focus on a related issue. We discuss the development of blogs, and the virtual “space” where blogs and bloggers interact the “blogosphere” and their impact on the issue of workers' privacy. To some extent it would seem a bit of a contradiction to talk about privacy and blogging in the same article. Blogging, as we will discuss below, does not appear to be the most private of enterprises. There are, we argue, a number of interesting privacy issues raised by the development of blogs as an employee communication tool and by the way employers have reacted …

Does The Third Law Of Thermodynamics Hold In The Quantum Regime?, R. F. O'Connell Jul 2006

Does The Third Law Of Thermodynamics Hold In The Quantum Regime?, R. F. O'Connell

Faculty Publications

The first in a long series of papers by John T. Lewis, in collaboration with G. W. Ford and the present author, considered the problem of the most general coupling of a quantum particle to a linear passive heat bath, in the course of which they derived an exact formula for the free energy of an oscillator coupled to a heat bath in thermal equilibrium at temperature $T$. This formula, and its later extension to three dimensions to incorporate a magnetic field, has proved to be invaluable in analyzing problems in quantum thermodynamics. Here, we address the question raised in …

Lanthanide Complexes As Fluorescent Indicators For Neutral Sugars And Cancer Biomarkers, Onur Alptürk, Oleksandr Rusin, Sayo O. Fakayode, Weihua Wang, Jorge O. Escobedo, Isiah M. Warner, William E. Crowe, Vladimir Král, Jeff M. Pruet, Robert M. Strongin

Faculty Publications

Simple water-soluble lanthanum and europium complexes are effective at detecting neutral sugars as well as glycolipids and phospholipids. In solutions at physiologically relevant pH the fluorescent lanthanum complex binds neutral sugars with apparent binding constants comparable to those of arylboronic acids. Interference from commonly occurring anions is minimal. The europium complex detects sialic acid-containing gangliosides at pH 7.0 over an asialoganglioside. This selectivity is attributed, in large part, to the cooperative complexation of the oligosaccharide and sialic acid residues to the metal center, based on analogous prior studies. In MeOH, lysophosphatidic acid (LPA), a biomarker for several pathological conditions including …

Sequence Of Linear Programming For Transmission Of Fine-Scalable Coded Content In Bandwidth-Limited Environments, Xiao Su, Tao Wang Jun 2006

Sequence Of Linear Programming For Transmission Of Fine-Scalable Coded Content In Bandwidth-Limited Environments, Xiao Su, Tao Wang

Faculty Publications

In this paper, we propose an optimal peer assignment algorithm on peer-to-peer networks. This algorithm is designed to maximize the quality of transmitting fine-scalable coded content by exploiting the embedding property of scalable coding. To be more realistic, we assume that the requesting peer has a delay constraint to display the content within a certain delay bound, and it also has limited incoming bandwidth. We first use a simple example to illustrate the peer assignment problem, and then formulate this problem as a linear programming problem, followed by a nonlinear programming problem. To efficiently solve the second nonlinear problem, we …

Origin And Health Impacts Of Emissions Of Toxic By-Products And Fine Particles From Combustion And Thermal Treatment Of Hazardous Wastes And Materials, Stephania A. Cormier, Slawo Lomnicki, Wayne Backes, Barry Dellinger

Faculty Publications

High-temperature, controlled incineration and thermal treatment of contaminated soils, sediments, and wastes at Superfund sites are often preferred methods of remediation of contaminated sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and related legislation. Although these methods may be executed safely, formation of toxic combustion or reaction by-products is still a cause of concern. Emissions of polycyclic aromatic hydrocarbons (PAHs); chlorinated hydrocarbons (CHCs), including polychlorinated dibenzo-p-dioxins and dibenzofurans; and toxic metals (e.g., chromium VI) have historically been the focus of combustion and health effects research. However, fine particulate matter (PM) and ultrafine PM, which have been …
