Bacterial Artificial Chromosome Clones Of Viruses Comprising The Towne Cytomegalovirus Vaccine, Xiaohong Cui, Stuart P. Adler, Andrew J. Davison, Larry Smith, El-Sayed E. Habib, Michael A. Mcvoy
Pediatrics Publications
Bacterial artificial chromosome (BAC) clones have proven invaluable for genetic manipulation of herpesvirus genomes. BAC cloning can also be useful for capturing representative genomes that comprise a viral stock or mixture. The Towne live attenuated cytomegalovirus vaccine was developed in the 1970s by serial passage in cultured fibroblasts. Although its safety, immunogenicity, and efficacy have been evaluated in nearly a thousand human subjects, the vaccine itself has been little studied. Instead, genetic composition and in vitro growth properties have been inferred from studies of laboratory stocks that may not always accurately represent the viruses that comprise the vaccine. Here we …

Pharmacotherapy and Outcomes Science Publications
Intravenous (IV) iron and Erythropoiesis Stimulating Agents (ESAs) are recommended for anemia management in chronic kidney disease (CKD). This retrospective cohort study analyzed utilization patterns of IV iron and ESA in patients over 18 years of age admitted to University Health System Hospitals with a primary or secondary diagnosis of CKD between January 1, 2006 to December 31, 2008. A clustered binomial logistic regression using the GEE methodology was used to identify predictors of IV iron utilization. Only 8% (n = 6678) of CKD patients on ESA therapy received IV iron supplementation in university hospitals. Those receiving iron used significantly …

Pharmacotherapy and Outcomes Science Publications
Background
Heart failure (HF) is a complex clinical syndrome characterized by impaired cardiac function and poor exercise tolerance. Enhanced inflammation is associated with worsening outcomes in HF patients and may play a direct role in disease progression. Interleukin-1β (IL-1β) is a pro-inflammatory cytokine that becomes chronically elevated in HF and exerts putative negative inotropic effects.
Methods and Results
We developed a model of IL-1β-induced left ventricular (LV) dysfunction in healthy mice that exhibited a 32% reduction in LV fractional shortening (P
Conclusions
These findings suggest that IL-1β activity contributes to poor exercise tolerance in patients with systolic HF and identifies …

Atorvastatin With Or Without An Antibody To Pcsk9 In Primary Hypercholesterolemia, Eli M. Roth, James M. Mckenny, Corinne Hanotin, Gaelle Asset, Evan A. Stein
Pharmacotherapy and Outcomes Science Publications
Background
Serum proprotein convertase subtilisin/kexin 9 (PCSK9) binds to low-density lipoprotein (LDL) receptors, increasing the degradation of LDL receptors and reducing the rate at which LDL cholesterol is removed from the circulation. REGN727/SAR236553 (designated here as SAR236553), a fully human PCSK9 monoclonal antibody, increases the recycling of LDL receptors and reduces LDL cholesterol levels.
Methods
We performed a phase 2, multicenter, double-blind, placebo-controlled trial involving 92 patients who had LDL cholesterol levels of 100 mg per deciliter (2.6 mmol per liter) or higher after treatment with 10 mg of atorvastatin for at least 7 weeks. Patients were randomly assigned to …

Kendler, Jonathan Flint, Hong Deng
Psychiatry Publications
Background
Diagnostic information for psychiatric research often depends on both clinical interviews and medical records. Although discrepancies between these two sources are well known, there have been few studies into the degree and origins of inconsistencies.
Principal findings
We compared data from structured interviews and medical records on 1,970 Han Chinese women with recurrent DSM-IV major depression (MD). Correlations were high for age at onset of MD (0.93) and number of episodes (0.70), intermediate for family history (+0.62) and duration of longest episode (+0.43) and variable but generally more modest for individual depressive symptoms (mean kappa = 0.32). Four factors …
Comparison Of Statistical Tests For Association Between Rare Variants And Binary Traits, Silviu-Alin Bacanu, Matthew R. Nelson, John C. Whittaker
Comparison Of Statistical Tests For Association Between Rare Variants And Binary Traits, Silviu-Alin Bacanu, Matthew R. Nelson, John C. Whittaker
Psychiatry Publications
Genome-wide association studies have found thousands of common genetic variants associated with a wide variety of diseases and other complex traits. However, a large portion of the predicted genetic contribution to many traits remains unknown. One plausible explanation is that some of the missing variation is due to the effects of rare variants. Nonetheless, the statistical analysis of rare variants is challenging. A commonly used method is to contrast, within the same region (gene), the frequency of minor alleles at rare variants between cases and controls. However, this strategy is most useful under the assumption that the tested variants have …

Network-Assisted Investigation Of Combined Causal Signals From Genome-Wide Association Studies In Schizophrenia, Peilin Jia, Lily Wang, Ayman H. Fanous, Carlos N. Pato, Todd L. Edwards, Zhongming Zhao
Psychiatry Publications
With the recent success of genome-wide association studies (GWAS), a wealth of association data has been accomplished for more than 200 complex diseases/traits, proposing a strong demand for data integration and interpretation. A combinatory analysis of multiple GWAS datasets, or an integrative analysis of GWAS data and other high-throughput data, has been particularly promising. In this study, we proposed an integrative analysis framework of multiple GWAS datasets by overlaying association signals onto the protein-protein interaction network, and demonstrated it using schizophrenia datasets. Building on a dense module search algorithm, we first searched for significantly enriched subnetworks for schizophrenia in each …

One of the most significant evolutionary changes underlying the highly developed cognitive abilities of humans is the greatly enlarged brain volume. In addition to being far greater than in most other species, the volume of the human brain exhibits extensive variation and distinct sexual dimorphism in the general population. However, little is known about the genetic mechanisms underlying normal variation as well as the observed sex difference in human brain volume. Here we show that interleukin-3 (IL3) is strongly associated with brain volume variation in four genetically divergent populations. We identified a sequence polymorphism (rs31480) in the IL3 promoter which …
Evolutionary Optimization Of Electronic Circuitry Cooling Using Nanofluid, Manu Mital
Evolutionary Optimization Of Electronic Circuitry Cooling Using Nanofluid, Manu Mital
Mechanical and Nuclear Engineering Publications
Liquid cooling electronics using microchannels integrated in the chips is an attractive alternative to bulky aluminum heat sinks. Cooling can be further enhanced using nanofluids. The goals of this study are to evaluate heat transfer in a nanofluid heat sink with developing laminar flow forced convection, taking into account the pumping power penalty. The proposed model uses semi-empirical correlations to calculate effective nanofluid thermophysical properties, which are then incorporated into heat transfer and friction factor correlations in literature for single-phase flows. The model predicts the thermal resistance and pumping power as a function of four design variables that include the …
Optimizing Fiber Cross-Sectional Shape For Improving Stability Of Air–Water Interface Over Superhydrophobic Fibrous Coatings, B. Emami, Hooman Vahedi Tafreshi
Optimizing Fiber Cross-Sectional Shape For Improving Stability Of Air–Water Interface Over Superhydrophobic Fibrous Coatings, B. Emami, Hooman Vahedi Tafreshi
Mechanical and Nuclear Engineering Publications
In this letter, a mathematical force-balance formulation is developed that can be used to predict the critical pressure, the hydrostaticpressure above which the surface starts to depart from the non-wetting state, for superhydrophobicsurfaces comprised of highly aligned fibers (e.g., biased AC-electrospun coatings) with arbitrary cross-sectional shapes. We have also developed a methodology for optimizing the fiber cross-sections to maximize the critical pressure of the surface, using the Euler–Lagrange equation. A case study is presented to better demonstrate the application of our method.
Size And Shape Control Of Gold Nanodeposits In An Array Of Silica Nanowells On A Gold Electrode, Amy E. Rue, Maryanne M. Collinson
Size And Shape Control Of Gold Nanodeposits In An Array Of Silica Nanowells On A Gold Electrode, Amy E. Rue, Maryanne M. Collinson
Chemistry Publications
Ordered arrays of hemispherical nanowells were formed in a sol-gel-derived silica film on a gold electrode using 500 nm diameter polystyrene latex spheres as templates. The conductive domain located at the bottom of each nanowell upon template removal was enlarged via electroless deposition from a gold plating solution. The structured electrodes thus formed were characterized using scanning electron microscopy and atomic force microscopy. Depending on the method used to make the films, the extent of the long-range packing and the size of the conductive domain changed. Electroless deposition in the nanowells produced (near) sphere-like nanostructures of gold, the size of …
Magnetic Properties Of Co2c And Co3c Nanoparticles And Their Assemblies, Kyler J. Carroll, Zachary J. Huba, Steven R. Spurgeon, Meichun Qian, Shiv N. Khanna, Daniel M. Hudgins, Mitra L. Taheri, Everett E. Carpenter
Magnetic Properties Of Co2c And Co3c Nanoparticles And Their Assemblies, Kyler J. Carroll, Zachary J. Huba, Steven R. Spurgeon, Meichun Qian, Shiv N. Khanna, Daniel M. Hudgins, Mitra L. Taheri, Everett E. Carpenter
Chemistry Publications
Nano-composite material consisting of Co2C and Co3C nanoparticles has recently been shown to exhibit unusually large coercivities and energy products. Experimental studies that can delineate the properties of individual phases have been undertaken and provide information on how the coercivities and the energy product change with the size and composition of the nanoparticles. The studies indicate that while both phases are magnetic, the Co3C has higher magnetization and coercivity compared to Co2C. Through first principles electronic structure studies using a GGA+U functional, we provide insight on the role of C intercalation on …
Controlled Synthesis Of Superparamagnetic Iron-Oxide Nanoparticles By Phase Transformation, Mark A. Laurenzi, Everett E. Carpenter
Controlled Synthesis Of Superparamagnetic Iron-Oxide Nanoparticles By Phase Transformation, Mark A. Laurenzi, Everett E. Carpenter
Chemistry Publications
A synthesis procedure for generating a uniform distribution of iron-oxide nanoparticles from an amorphous precursor is reported. The investigation suggests no evidence of the formation of unwanted surface oxide layers, internal stress, and multiple phases. This is likely because the physical properties of the diffusion fields surrounding the nanoparticles are self-limiting by Fe(II) depletion. Inside the diffusion field surrounding the nucleation site, decreasing Fe(II) concentration results in a decrease in the diffusion rate that continues to decrease until self-limiting kinetic arrest occurs. The initial Fe(II) concentration is established by reducing a system abundant in Fe(III) by means of exposure to …
Wettability Of Pristine And Alkyl-Functionalized Graphane, Davide Vanzo, Dusan Bratko, Alenka Luzar
Wettability Of Pristine And Alkyl-Functionalized Graphane, Davide Vanzo, Dusan Bratko, Alenka Luzar
Chemistry Publications
Graphane is a hydrogenated form of graphene with high bandgap and planar structure insensitive to a broad range of chemical substitutions. We describe an atomistic simulation approach to predict wetting properties of this new material. We determine the contact angle to be 73°. The lower hydrophobicity compared to graphene is explained by the increased planar density of carbon atoms while we demonstrate that the presence of partial charges on carbonand hydrogen atoms plays only a minor role. We further examine the effects of graphane functionalization by alkyl groups of increasing chain lengths. The gradual increase in contact angle with chain …
Low Dose Nicotine And Antagonism Of Β2 Subunit Containing Nicotinic Acetylcholine Receptors Have Similar Effects On Affective Behavior In Mice, Shawn M. Anderson, Darlene H. Brunzell
Low Dose Nicotine And Antagonism Of Β2 Subunit Containing Nicotinic Acetylcholine Receptors Have Similar Effects On Affective Behavior In Mice, Shawn M. Anderson, Darlene H. Brunzell
Pharmacology and Toxicology Publications
Nicotine leads to both activation and desensitization (inactivation) of nicotinic acetylcholine receptors (nAChRs). This study tested the hypothesis that nicotine and a selective antagonist of β2*nAChRs would have similar effects on affective behavior. Adult C57BL/6J male mice were tested in a conditioned emotional response (CER) assay which evaluates the ability of an aversive stimulus to inhibit goal-directed behavior. Mice lever-pressed for a saccharin reinforcer according to a variable schedule of reinforcement during sessions in which two presentations of a compound light/tone conditioned stimulus (CS) co-terminated with a 0.1 or 0.3 mA, 0.5 s footshock unconditioned stimulus (US). During testing in …

Interaction Between Mu And Delta Opioid Receptor Agonists In An Assay Of Capsaicin-Induced Thermal Allodynia In Rhesus Monkeys, S. Stevens Negus, Ember Morrissey, John E. Folk, Kenner C. Rice
Pharmacology and Toxicology Publications
Delta opioid agonists enhance antinociceptive effects of mu-opioid agonists in many preclinical assays of acute nociception, but delta/mu interactions in preclinical models of inflammation-associated pain have not been examined. This study examined interactions between the delta agonist SNC80 [(+)-4-[(αR)-α-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]-N,N-diethylbenzamide] and the mu agonist analgesics methadone, morphine, and nalbuphine in an assay of capsaicin-induced thermal allodynia in rhesus monkeys. Thermal allodynia was produced by topical application of capsaicin to the tail. Antiallodynic effects of methadone, morphine, and nalbuphine were evaluated alone or in combination with fixed proportions of SNC80 identical to proportions previously shown to enhance acute thermal antinociceptive effects of …
Preclinical Determinants Of Drug Choice Under Concurrent Schedules Of Drug Self-Administration, Matthew L. Banks, S. Stevens Negus
Preclinical Determinants Of Drug Choice Under Concurrent Schedules Of Drug Self-Administration, Matthew L. Banks, S. Stevens Negus
Pharmacology and Toxicology Publications
Drug self-administration procedures have played a critical role in the experimental analysis of psychoactive compounds, such as cocaine, for over 50 years. While there are numerous permutations of this procedure, this paper will specifically focus on choice procedures using concurrent schedules of intravenous drug self-administration. The aims of this paper are to first highlight the evolution of drug choice procedures and then review the subsequent preclinical body of literature utilizing these choice procedures to understand the environmental, pharmacological, and biological determinants of the reinforcing stimulus effects of drugs. A main rationale for this paper is our proposition that choice schedules …
Processing Of Damaged Dna Ends For Double-Strand Break Repair In Mammalian Cells, Lawrence F. Povirk
Processing Of Damaged Dna Ends For Double-Strand Break Repair In Mammalian Cells, Lawrence F. Povirk
Pharmacology and Toxicology Publications
Most DNA double-strand breaks (DSBs) formed in a natural environment have chemical modifications at or near the ends that preclude direct religation and require removal or other processing so that rejoining can proceed. Free radical-mediated DSBs typically bear unligatable 3′-phosphate or 3′-phosphoglycolate termini and often have oxidized bases and/or abasic sites near the break. Topoisomerase-mediated DSBs are blocked by covalently bound peptide fragments of the topoisomerase. Enzymes capable of resolving damaged ends include polynucleotide kinase/phosphatase, which restores missing 5′-phosphates and removes 3′-phosphates; tyrosyl-DNA phosphodiesterases I and II (TDP1 and TDP2), which remove peptide fragments of topoisomerases I and II, respectively; …
Mdan-21: A Bivalent Opioid Ligand Containing Mu-Agonist And Delta-Antagonist Pharmacophores And Its Effects In Rhesus Monkeys, Mario D. Aceto, Louis S. Harris, S. Stevens Negus, Matthew L. Banks, Larry D. Hughes, Eyup Akgun, Philip S. Portoghese
Mdan-21: A Bivalent Opioid Ligand Containing Mu-Agonist And Delta-Antagonist Pharmacophores And Its Effects In Rhesus Monkeys, Mario D. Aceto, Louis S. Harris, S. Stevens Negus, Matthew L. Banks, Larry D. Hughes, Eyup Akgun, Philip S. Portoghese
Pharmacology and Toxicology Publications
MDAN-21, , a bivalent opioid ligand containing a mu-opioid receptor agonist (derived from oxymorphone) linked to the delta-opioid receptor antagonist (related to naltrindole) by a spacer of 21 atoms, was reported to have potent analgesic properties in mice. Tolerance, physical dependence, and conditioned place preference were not evident in that species. The finding that bivalent ligands in this series, with spacers 19 atoms or greater, were devoid of tolerance and dependence led to the proposal that MDAN-21 targets heteromeric mu-delta-opioid receptors. The present study focused on its effects in nonhuman primates (Macaca mulatta), a species with a physiology and behavioral …

Pharmacology and Toxicology Publications
Aims and Hypothesis
Glucose-stimulated insulin secretion from beta-cells is a tightly regulated process that requires calcium flux to trigger exocytosis of insulin-containing vesicles. Regulation of calcium handling in beta-cells remains incompletely understood. Gem, a member of the RGK (Rad/Gem/Kir) family regulates calcium channel handling in other cell types, and Gem over-expression inhibits insulin release in insulin-secreting Min6 cells. The aim of this study was to explore the role of Gem in insulin secretion. We hypothesised that Gem may regulate insulin secretion and thus affect glucose tolerance in vivo.
Methods
Gem-deficient mice were generated and their metabolic phenotype characterised by …

Acid Sphingomyelinase Gene Knockout Ameliorates Hyperhomocysteinemic Glomerular Injury In Mice Lacking Cystathionine-Β-Synthase, Krishna M. Boini, Min Xia, Justine M. Abais, Ming Xu, Cai-Xia Li, Pin-Lan Li
Pharmacology and Toxicology Publications
Acid sphingomyelinase (ASM) has been implicated in the development of hyperhomocysteinemia (hHcys)-induced glomerular oxidative stress and injury. However, it remains unknown whether genetically engineering of ASM gene produces beneficial or detrimental action on hHcys-induced glomerular injury. The present study generated and characterized the mice lacking cystathionine β-synthase (Cbs) and Asm mouse gene by cross breeding Cbs+/− and Asm+/− mice. Given that the homozygotes of Cbs−/−/Asm−/− mice could not survive for 3 weeks. Cbs+/−/Asm+/+, Cbs+/−/Asm+/− and Cbs+/−/Asm−/− as well as their Cbs wild type littermates were used to study the role of Asm−/− under a background of Cbs+/− with hHcys. HPLC …

Pharmacology and Toxicology Publications
It was suggested that endocannabinoids are metabolized by cyclooxygenase (COX)-2 in the spinal cord of rats with kaolin/λ-carrageenan-induced knee inflammation, and that this mechanism contributes to the analgesic effects of COX-2 inhibitors in this experimental model. We report the development of a specific method for the identification of endocannabinoid COX-2 metabolites, its application to measure the levels of these compounds in tissues, and the finding of prostamide F2α (PMF2α) in mice with knee inflammation. Whereas the levels of spinal endocannabinoids were not significantly altered by kaolin/λ-carrageenan-induced knee inflammation, those of the COX-2 metabolite of AEA, PMF2α, were strongly elevated. The …

This paper describes the ways in which libraries are currently implementing and managing web-based research guides (a.k.a. Pathfinders, LibGuides, Subject Guides, etc.) by examining two sets of data from the spring of 2011. One set of data was compiled by visiting the websites of ninety-nine American university ARL libraries and recording the characteristics of each site’s research guides. The other set of data is based on an online survey of librarians about the ways in which their libraries implement and maintain research guides. In conclusion, a discussion follows that includes implications for the library technology community.
