© 2014 Elsevier Ltd All rights reserved. Despite tremendous successes of GPCR crystallography, the receptors with available structures represent only a small fraction of human GPCRs. An important role of the modeling community is to maximize structural insights for the remaining receptors and complexes. The community-wide GPCR Dock assessment was established to stimulate and monitor the progress in molecular modeling and ligand docking for GPCRs. The four targets in the present third assessment round presented new and diverse challenges for modelers, including prediction of allosteric ligand interaction and activation states in 5-hydroxytryptamine receptors 1B and 2B, and modeling by extremely …

Nucleolar Stress With And Without P53, Allison James, Yubo Wang, Himanshu Raje, Raphyel Rosby, Patrick Dimario

Faculty Publications

Averitable explosion of primary research papers within the past 10 years focuses on nucleolar and ribosomal stress, and for good reason: with ribosome biosynthesis consuming ∼80% of a cell’s energy, nearly all metabolic and signaling pathways lead ultimately to or from the nucleolus. We begin by describing p53 activation upon nucleolar stress resulting in cell cycle arrest or apoptosis. The significance of this mechanism cannot be understated, as oncologists are now inducing nucleolar stress strategically in cancer cells as a potential anti-cancer therapy. We also summarize the human ribosomopathies, syndromes in which ribosome biogenesis or function are impaired leading to …

Communication: Using Multiple Tethers To Stabilize Proteins On Surfaces, Brandon K. Loong, Thomas A. Knotts Iv

Faculty Publications

Protein surface interactions are important in many applications in biotechnology including protein arrays, but these technologies have not lived up to their transformative potential because it is difficult to attach proteins to surfaces in a manner that preserves function and theoretical understanding of the relevant phenomena remains limited. Here is reported the effect of using multiple tethers to attach a protein (lysozyme) to a surface and the effects on the structure and stability of the molecule. The simulations show how using two tethers can drastically change the folding mechanism such that a protein that is initially unstable and inactive when …

We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particles, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that …

Cdk1 Promotes Cytokinesis In Fission Yeast Through Activation Of The Septation Initiation Network, Nicole Rachfall, Alyssa E. Johnson, Sapna Mehta, Jun Song Chen, Kathleen L. Gould

Faculty Publications

In Schizosaccharomyces pombe, late mitotic events are coordinated with cytokinesis by the septation initiation network (SIN), an essential spindle pole body (SPB)-associated kinase cascade, which controls the formation, maintenance, and constriction of the cytokinetic ring. It is not fully understood how SIN initiation is temporally regulated, but it depends on the activation of the GTPase Spg1, which is inhibited during interphase by the essential bipartite GTPase-activating protein Byr4-Cdc16. Cells are particularly sensitive to the modulation of Byr4, which undergoes cell cycle-dependent phosphorylation presumed to regulate its function. Polo-like kinase, which promotes SIN activation, is partially responsible for Byr4 phosphorylation. Here …

Serotonin Transporter Genotype Modulates Hpa Axis Output During Stress: Effect Of Stress, Dexamethasone Test And Acth Challenge, Andrea N. Sorenson, Erin C. Sullivan, Sally P. Mendoza, John P. Capitanio, James Dee Higley

Faculty Publications

Background—Studies show that the hypothalamic–pituitary–adrenal (HPA) axis is dysregulated in depression. Some studies suggest that variation in the serotonin transporter genotype (hereafter 5HTT) modulates both risk for depression and psychopathological HPA axis responsiveness. Rhesus monkeys are well suited to model such relationships. Rhesus macaque models of human psychopathology have assessed the effect of the serotonin transporter (rh5HTT) on levels of cortisol in stressed subjects. These studies show that that under conditions of stress, heterozygous females (Ls) reared under adversity exhibit high levels of cortisol. Studies have not to our knowledge, however, assessed the potential additive effect on the cortisol response …

Integrating Microbial Physiology And Physio-Chemical Principles In Soils With The Microbial-Mineral Carbon Stabilization (Mimics) Model, William R. Wieder, A. Stuart Grandy, Cynthia M. Kallenbach, Gordon B. Bonan

Faculty Publications

A growing body of literature documents the pressing need to develop soil biogeochemistry models that more accurately reflect contemporary understanding of soil processes and better capture soil carbon (C) responses to environmental perturbations. Models that explicitly represent microbial activity offer inroads to improve representations of soil biogeochemical processes, but have yet to consider relationships between litter quality, functional differences in microbial physiology, and the physical protection of microbial byproducts in forming stable soil organic matter (SOM). To address these limitations, we introduce the MIcrobial-MIneral Carbon Stabilization (MIMICS) model, and evaluate it by comparing site-level soil C projections with observations from …

The Effect Of Platelet-Rich Plasma (Prp) On Muscle Contusion Healing In A Rat Model., Demetris Delos, Matthew J. Leineweber, Salma Chaudhury, Saif Alzoobaee, Yingxin Gao, Scott Alan Rodeo

Faculty Publications

Background: Current therapy for muscle contusions is usually limited to nonsteroidal anti-inflammatory drugs and/or use of the RICE principle (rest, ice, compression, elevation); thus, other forms of treatment that can potentially accelerate the rate of healing are desirable. Hypotheses: A local injection of platelet-rich plasma (PRP) would lead to accelerated healing rates compared with controls; also, delayed administration of PRP would lead to a blunted response compared with immediate treatment. Study Design: Controlled laboratory study. Methods: Forty-six male Lewis rats each underwent a single blunt, nonpenetrating impact to the gastrocnemius muscle via a drop-mass technique and subsequently received either a …

Digital Anthropomorphic Phantoms Of Non-Rigid Human Respiratory And Voluntary Body Motion For Investigating Motion Correction In Emission Imaging, Arda Könik, Caitlin M. Connolly, Karen L. Johnson, Paul Dasari, Paul W. Segars, P. H. Pretorius, Clifford Lindsay, Joyoni Dey, Michael A. King

Faculty Publications

The development of methods for correcting patient motion in emission tomography has been receiving increased attention. Often the performance of these methods is evaluated through simulations using digital anthropomorphic phantoms, such as the commonly used extended cardiac torso (XCAT) phantom, which models both respiratory and cardiac motion based on human studies. However, non-rigid body motion, which is frequently seen in clinical studies, is not present in the standard XCAT phantom. In addition, respiratory motion in the standard phantom is limited to a single generic trend. In this work, to obtain a more realistic representation of motion, we developed a series …

Ligand-Binding Pocket Bridges Dna-Binding And Dimerization Domains Of The Urate-Responsive Marr Homologue Mftr From Burkholderia Thailandensis, Ashish Gupta, Anne Grove

Faculty Publications

Members of the multiple antibiotic resistance regulator (MarR) family often regulate gene activity by responding to a specific ligand. In the absence of ligand, most MarR proteins function as repressors, while ligand binding causes attenuated DNA binding and therefore increased gene expression. Previously, we have shown that urate is a ligand for MftR (major facilitator transport regulator), which is encoded by the soil bacterium Burkholderia thailandensis. We show here that both mftR and the divergently oriented gene mftP encoding a major facilitator transport protein are upregulated in the presence of urate. MftR binds two cognate sites in the mftR-mftP intergenic …

Iron Porphyrin Carbenes As Catalytic Intermediates: Structures, Mössbauer And Nmr Spectroscopic Properties, And Bonding, Rahul L. Khade, Wenchao Fan, Yan Ling, Liu Yang, Eric Oldfield, Yong Zhang

Faculty Publications

Iron porphyrin carbenes (IPCs) are thought to be intermediates involved in the metabolism of various xenobiotics by cytochrome P450, as well as in chemical reactions catalyzed by metalloporphyrins and engineered P450s. While early work proposed IPCs to contain Fe^II, more recent work invokes a double-bond description of the iron–carbon bond, similar to that found in Fe^IV porphyrin oxenes. Reported herein is the first quantum chemical investigation of IPC Mössbauer and NMR spectroscopic properties, as well as their electronic structures, together with comparisons to ferrous heme proteins and an Fe^IV oxene model. The results provide the first …

Land-Use Legacies Regulate Decomposition Dynamics Following Bioenergy Crop Conversion, Cynthia M. Kallenbach, A. Stuart Grandy

Faculty Publications

Land-use conversion into bioenergy crop production can alter litter decomposition processes tightly coupled to soil carbon and nutrient dynamics. Yet, litter decomposition has been poorly described in bioenergy production systems, especially following land-use conversion. Predicting decomposition dynamics in postconversion bioenergy production systems is challenging because of the combined influence of land-use legacies with current management and litter quality. To evaluate how land-use legacies interact with current bioenergy crop management to influence litter decomposition in different litter types, we conducted a landscape-scale litterbag decomposition experiment. We proposed land-use legacies regulate decomposition, but their effects are weakened under higher quality litter and …

Genetic Analysis And Prevalence Studies Of The Brp Exopolysaccharide Locus Of Vibrio Vulnificus, Katherine L. Garrison-Schilling, Zelam M. Kaluskar, Bliss Lambert, Gregg S. Pettis

Faculty Publications

Phase variation in the Gram-negative human pathogen Vibrio vulnificus involves three colonial morphotypes- smooth opaque colonies due to production of capsular polysaccharide (CPS), smooth translucent colonies as the result of little or no CPS expression, and rugose colonies due to production of a separate extracellular polysaccharide (EPS), which greatly enhances biofilm formation. Previously, it was shown that the brp locus, which consists of nine genes arranged as an operon, is up-regulated in rugose strains in a c-di-GMP-dependent manner, and that plasmid insertions into the locus resulted in loss of rugosity and efficient biofilm production. Here, we have used non-polar mutagenesis …

Weekly And Holiday-Related Patterns Of Panic Attacks In Panic Disorder: A Population-Based Study, Li-Ting Kao, Sudha Xirasagar, Kuo-Hsuan Chung, Herng-Ching Lin, Shih-Ping Liu, Shiu-Dong Chung

Faculty Publications

Background: While chronobiological studies have reported seasonal variation in panic attacks (PA) episodes, information on the timing of PA by week-days may enable better understanding of the triggers of PA episodes and thereby provide pointers for suitable interventional approaches to minimize PA attacks. This study investigated weekly variation in potential PA admissions including associations with holidays using a population-based longitudinal, administrative claims-based dataset in an Asian population.

Methods: This study used ambulatory care data from the ‘‘Longitudinal Health Insurance Database 2000. We identified 993 patients with panic disorder (PD), and they had 4228 emergency room (ER) admissions for potential PA …

High-Throughput Targeted Repeat Element Bisulfite Sequencing (Ht-Trebs): Genome-Wide Dna Methylation Analysis Of Iap Ltr Retrotransposon, Muhammad B. Ekram, Joomyeong Kim

Faculty Publications

In vertebrates, DNA methylation-mediated repression of retrotransposons is essential for the maintenance of genomic integrity. In the current study, we developed a technique termed HT-TREBS (High-Throughput Targeted Repeat Element Bisulfite Sequencing). This technique is designed to measure the DNA methylation levels of individual loci of any repeat families with next-generation sequencing approaches. To test the feasibility of HT-TREBS, we analyzed the DNA methylation levels of the IAP LTR family using a set of 12 different genomic DNA isolated from the brain, liver and kidney of 4 one-weekold littermates of the mouse strain C57BL/6N. This technique has successfully generated the CpG …

Effects Of Nutritional Level Of Concentrate‐Based Diets On Meat Quality And Expression Levels Of Genes Related To Meat Quality In Hainan Black Goats, Dingfa Wang, Luli Zhou, Hanlin Zhou, Guanyu Hou, Liguang Shi, Mao Li, Xianzhou Huang, Song Guan

Faculty Publications

The present study investigated the effects of the nutritional levels of diets on meat quality and related gene expression in Hainan black goat. Twenty-four goats were divided into six dietary treatments and were fed a concentrate-based diet with two levels of crude protein (CP) (15% or 17%) and three levels of digestive energy (DE) (11.72, 12.55 or 13.39 MJ/kg DM) for 90 days. Goats fed the concentrate-based diet with 17% CP had significantly (P < 0.05) higher average daily gains (ADG) and better feed conversion rates (FCR). The pH 24h value tended to decrease (P < 0.05) with increasing DE levels. The tenderness of Longissimus dorsi muscle (LD) and Semimembranosus muscle (SM) reduced with increasing CP levels (P < 0.05). With increasing DE levels, tenderness was increased (P < 0.05). The heart fatty acid-binding protein (H-FABP) mRNA expression levels in LD and SM increased with increasing DE levels (P < 0.05), but decreased with increasing CP levels (P < 0.05). The calpastatin (CAST) and μ-calpain mRNA expressions levels in LD and SM were affected significantly (P < 0.05) by CP and DE levels in the diet. Therefore, the nutritional levels of diets affect meat quality and expression levels of genes associated with meat quality in Hainan black goats.

4d Optimization Of Scanned Ion Beam Tracking Therapy For Moving Tumors, John Gordon Eley, Wayne David Newhauser, Robert Lüchtenborg, Christian Graeff, Christoph Bert

Faculty Publications

Motion mitigation strategies are needed to fully realize the theoretical advantages of scanned ion beam therapy for patients with moving tumors. The purpose of this study was to determine whether a new four-dimensional (4D) optimization approach for scanned-ion-beam tracking could reduce dose to avoidance volumes near a moving target while maintaining target dose coverage, compared to an existing 3D-optimized beam tracking approach. We tested these approaches computationally using a simple 4D geometrical phantom and a complex anatomic phantom, that is, a 4D computed tomogram of the thorax of a lung cancer patient. We also validated our findings using measurements of …

Chemicals Facilitating Reprogramming: Targeting The Sam Binding Site To Identify Novel Methyltransferase Inhibitors, Jeong Do Kim, Jong S. Rim, Robert B. Crochet, Yong Hwan Lee, Jaroslaw Staszkiewicz, Ru Gao, Kenneth J. Eilertsen

Faculty Publications

© 2014 John Wiley & Sons, Ltd. Reprogramming of somatic cells to a pluripotent state has been achieved by viral-mediated transduction of defined transcription factors. In order to achieve the goal of clinical application, it is necessary to overcome a variety of limitations, including poor reprogramming efficiencies and viral integration. One strategy is to identify small-molecule inhibitors that can improve reprogramming efficiency or replace defined transcription factors. Several reports have demonstrated that modulation of chromatin-modifying enzymes can significantly improve reprogramming efficiency. Key enzymes include DNA and histone methyltransferases, which utilize the cofactor S-adenosyl methionine (SAM) to transfer a methyl group. …

Rethinking Utopianism, International Relations Theory, And Marginalization Of Africa In Global Politics, Kwame B. Antwi-Boasiako

Faculty Publications

Many studies on utopianism tend to critique known political models such as capitalism, democracy, socialism, and dictatorship. While none of these models provide a perfect political environment, utopianism seems to be the answer to prevent all political abuses. From public administration point of view, the harmonious co-existence of all political models without any interference may help to conceptualise a potential change in our current hostile global political environment and limit the marginalisation of other societies as presented in the international relations literature. Modernisation theories, debatably, have assumed that the principles of modern political administration will become more important than other …

Multipolarity, Intellectual Property And The Internationalization Of Public Health Law, Sam F. Halabi

Faculty Publications

This Article critically examines the proliferation of international legal agreements addressing global health threats like the outbreak of infectious diseases, tobacco use and lack of access to affordable medicines. The conventional wisdom behind this trend is that a global normative shift has occurred which has caused states to regard health as “special” and less subject to the normal rules of international law making because health threats endanger all of humanity. This Article challenges that thesis, arguing that at the same time the number and scope of international health law treaties has grown, developed states have subordinated health law to intellectual …

Chronic Stress Alters Concentrations Of Corticosterone Receptors In A Tissue-Specific Manner In Wild House Sparrows (Passer Domesticus), Christine R. Lattin, L. Michael Romero

Faculty Publications

© 2014. Published by The Company of Biologists Ltd. The physiological stress response results in release of glucocorticoid hormones such as corticosterone (CORT). Whereas short-term activation of this response helps animals cope with environmental stressors, chronic activation can result in negative effects including metabolic dysregulation and reproductive failure. However, there is no consensus hormonal profile of a chronically stressed animal, suggesting that researchers may need to look beyond hormone titers to interpret the impacts of chronic stress. In this study, we brought wild house sparrows (Passer domesticus) into captivity. We then compared glucocorticoid and mineralocorticoid receptor concentrations in sparrows exposed …

Gelatinous Zooplankton Biomass In The Global Oceans: Geographic Variation And Environmental Drivers, Cathy H. Lucas, Daniel O.B. Jones, Catherine J. Hollyhead, Robert H. Condon, Carlos M. Duarte, William M. Graham, Kelly L. Robinson, Kylie A. Pitt, Mark Schildhauer, Jim Regetz

Faculty Publications

Aim

Scientific debate regarding the future trends, and subsequent ecological, biogeochemical and societal impacts, of gelatinous zooplankton (GZ) in a changing ocean is hampered by lack of a global baseline and an understanding of the causes of biogeographic patterns. We address this by using a new global database of GZ records to test hypotheses relating to environmental drivers of biogeographic variation in the multidecadal baseline of epipelagic GZ biomass in the world's oceans.

Location

Global oceans.

Methods

Over 476,000 global GZ data and metadata items were assembled from a variety of published and unpublished sources. From this, a total of …

Faculty Publications

© 2014 Colonna et al. Background: Population differentiation has proved to be effective for identifying loci under geographically localized positive selection, and has the potential to identify loci subject to balancing selection. We have previously investigated the pattern of genetic differentiation among human populations at 36.8 million genomic variants to identify sites in the genome showing high frequency differences. Here, we extend this dataset to include additional variants, survey sites with low levels of differentiation, and evaluate the extent to which highly differentiated sites are likely to result from selective or other processes. Results: We demonstrate that while sites with …

Amino Acids In The Uterine Luminal Fluid Reflects The Temporal Changes In Transporter Expression In The Endometrium And Conceptus During Early Pregnancy In Cattle, Niamh Forde, Constantine A. Simintiras, Roger Sturmey, Solomon Mamo, Alan K. Kelly, Thomas E. Spencer, Fuller W. Bazer, Pat Lonergan

Faculty Publications

In cattle, conceptus-maternal interactions are critical for the establishment and maintenance of pregnancy. A major component of this early interaction involves the transport of nutrients and secretion of key molecules by uterine epithelial cells to help support conceptus development during the peri-implantation period of pregnancy. Objectives were to: 1) analyze temporal changes in the amino acid (AA) content of uterine luminal fluid (ULF) during the bovine estrous cycle; 2) understand conceptus-induced alterations in AA content; 3) determine expression of AA transporters in the endometrium and conceptus; and 4) determine how these transporters are modulated by (Progesterone) P4. Concentrations of aspartic …

Are Undergraduate Gpa And General Gre Percentiles Valid Predictors Of Student Performance In An Engineering Graduate Program?, Larry L. Howell, Carl D. Sorenson, Matthew R. Jones

Faculty Publications

While both subjective measures and quantitative metrics play an important role in admissions decisions, quantitative metrics are amenable to critical analysis using the tools of academic analytics. The hypotheses that motivated this study are: 1. Can an applicant’s undergraduate grade point average (UGPA) and scores on the Graduate Records Examinations (GRE) be used to accurately predict the performance of the applicant in a graduate mechanical engineering program? 2. Is a single construct based on these quantitative predictive metrics a valuable tool in efficiently making admissions decisions? This study analyzed the relationship between quantitative predictive metrics, available at the time of …

Elaborate Visual And Acoustic Signals Evolve Independently In A Large, Phenotypically Diverse Radiation Of Songbirds, Nicholas A. Mason, Allison J. Shultz, Kevin J. Burns

Faculty Publications

The concept of a macroevolutionary trade-off among sexual signals has a storied history in evolutionary biology. Theory predicts that if multiple sexual signals are costly for males to produce or maintain and females prefer a single, sexually selected trait, then an inverse correlation between sexual signal elaborations is expected among species. However, empirical evidence for what has been termed the 'transfer hypothesis' is mixed, which may reflect different selective pressures among lineages, evolutionary covariates or methodological differences among studies. Here,we examine interspecific correlations between song and plumage elaboration in a phenotypically diverse, widespread radiation of songbirds, the tanagers. The tanagers …

Convergent Evolution Of Aquatic Foraging In A New Genus And Species (Rodentia: Muridae) From Sulawesi Island, Indonesia, Kevin C. Rowe, Anang S. Achmadi, Jacob A. Esselstyn

Faculty Publications

The island of Sulawesi, in Indonesia, lies at the crossroads of the Indo-Australian Archipelago and has remained isolated from the Asian (Sunda) and Australian (Sahul) continental shelves for at least the last 10 million years. Of the 50 native species of rodents on Sulawesi, all are endemic and represent the evolution of a variety of ecological and morphological forms within the Muridae and Sciuridae. Carnivorous rodents have evolved, perhaps independently, in Muridae from the Philippines, Sulawesi, and Sahul, but semi-aquatic murids are only known from Sahul. Here we describe a new genus and species of insectivorous water rat from Sulawesi. …
