Anonymization Of Dicom Electronic Medical Records For Radiation Therapy, Wayne Newhauser, Timothy Jones, Stuart Swerdloff, Warren Newhauser, Mark Cilia, Robert Carver, Andy Halloran, Rui Zhang

Faculty Publications

Electronic medical records (EMR) and treatment plans are used in research on patient outcomes and radiation effects. In many situations researchers must remove protected health information (PHI) from EMRs. The literature contains several studies describing the anonymization of generic Digital Imaging and Communication in Medicine (DICOM) files and DICOM image sets but no publications were found that discuss the anonymization of DICOM radiation therapy plans, a key component of an EMR in a cancer clinic. In addition to this we were unable to find a commercial software tool that met the minimum requirements for anonymization and preservation of data integrity …

Climate Balkanization: Dormant Commerce And The Limits Of State Energy Policy, Jonathan H. Adler

Faculty Publications

Through the imposition of mandates on what sorts of energy may be produced or sold, state regulatory efforts have imposed burdens on interstate energy markets. In some cases, these burdens are explicit, as when states have privileged in-state energy sources at the expense of out-of-state producers or sellers. In other cases, these burdens are the inevitable consequence of state efforts to reduce the environmental impacts of energy consumed within the state. Such restrictions, and their associated burdens on interstate commerce, raise serious constitutional questions. Under the so-called "Dormant Commerce Clause," state regulations that discriminate against out-of-state actors are presumptively unconstitutional, …

Robert Bork & Commercial Speech, Jonathan H. Adler

Faculty Publications

Before he redefined antitrust, Judge Robert Bork took aim at the First Amendment. Though his work in this area was not nearly as influential, it received substantial attention, particularly after President Ronald Reagan nominated Judge Bork to replace Justice Lewis Powell on the Supreme Court in 1987. Judge Bork's 1971 article, Neutral Principles and Some First Amendment Problems challenged the prevailing wisdom on the proper scope of First Amendment protections. In this article, published seven years before The Antitrust Paradox, Bork maintained that only "explicitly political" speech warranted constitutional protection. Other types of speech or expression, including much indisputably …

Paternally Expressed Peg3 Controls Maternally Expressed Zim1 As A Trans Factor, An Ye, Hongzhi He, Joomyeong Kim

Faculty Publications

© 2014 Ye et al. The expression of two adjacent imprinted genes, Peg3 and Zim1, is inversely correlated: down-regulation of Peg3 coinciding with up-regulation of Zim1. The current study characterized this inverse correlation using a mutant allele targeting Peg3. According to the results, the mutation on the paternal allele of Peg3 resulted in a dramatic increase in the transcription levels of the maternal allele of Zim1, suggesting the involvement of unknown trans factors in this trans-allelic event. Subsequent ChIP experiments revealed that the protein encoded by Peg3 itself binds to the zinc finger exon of Zim1, which is modified with …

Responses Of Sympatric Karenia Brevis, Prorocentrum Minimum, And Heterosigma Akashiwo To The Exposure Of Crude Oil, Koray Özhan, Sibel Bargu

Faculty Publications

Impacts of the Deepwater Horizon oil spill on phytoplankton, particularly, the tolerability and changes to the toxin profiles of harmful toxic algal species remain unknown. The degree to which oil-affected sympatric Karenia brevis, Prorocentrum minimum, and Heterosigma akashiwo, all of which are ecologically important species in the Gulf of Mexico, was investigated. Comparison of their tolerability to that of non-toxic species showed that the toxin-production potential of harmful species does not provide a selective advantage. Investigated toxin profiles for K. brevis and P. minimum demonstrated an increase in toxin productivity at the lowest crude oil concentration (0.66 mg L^{−1 …}

©2014 Macmillan Publishers Limited. All rights reserved. Gibbons are small arboreal apes that display an accelerated rate of evolutionary chromosomal rearrangement and occupy a key node in the primate phylogeny between Old World monkeys and great apes. Here we present the assembly and analysis of a northern white-cheeked gibbon (Nomascus leucogenys) genome. We describe the propensity for a gibbon-specific retrotransposon (LAVA) to insert into chromosome segregation genes and alter transcription by providing a premature termination site, suggesting a possible molecular mechanism for the genome plasticity of the gibbon lineage. We further show that the gibbon genera (Nomascus, Hylobates, Hoolock and …

Space Radiation: The Number One Risk To Astronaut Health Beyond Low Earth Orbit, Jeffery C. Chancellor, Graham B.I. Scott, Jeffrey P. Sutton

Faculty Publications

Projecting a vision for space radiobiological research necessitates understanding the nature of the space radiation environment and how radiation risks influence mission planning, timelines and operational decisions. Exposure to space radiation increases the risks of astronauts developing cancer, experiencing central nervous system (CNS) decrements, exhibiting degenerative tissue effects or developing acute radiation syndrome. One or more of these deleterious health effects could develop during future multi-year space exploration missions beyond low Earth orbit (LEO). Shielding is an effective countermeasure against solar particle events (SPEs), but is ineffective in protecting crew members from the biological impacts of fast moving, highly-charged galactic …

Intergeniculate Leaflet Lesions Result In Differential Activation Of Brain Regions Following The Presentation Of Photic Stimuli In Nile Grass Rats, Andrew J. Gall, Lily Yan, Laura Smale, Antonio A. Nunez

Faculty Publications

The intergeniculate leaflet (IGL) plays an important role in the entrainment of circadian rhythms and the mediation of acute behavioral responses to light (i.e., masking). Recently, we reported that IGL lesions in diurnal grass rats result in a reversal in masking responses to light as compared to controls. Here, we used Fos as a marker of neural activation to examine the mechanisms by which the IGL may influence this masking effect of light in grass rats. Specifically, we examined the patterns of Fos activation in retinorecipient areas and in brain regions that receive IGL inputs following 1-h light pulses given …

Transcriptional Profiles Of Bovine In Vivo Pre-Implantation Development, Zongliang Jiang, Jiangwen Sun, Hong Dong, Oscar Luo, Xinbao Zheng, Craig Obergfell, Yong Tang, Jinbo Bi, Rachel O'Neill, Yijun Ruan, Jingbo Chen, Xiuchun Tian

Faculty Publications

© 2014 Jiang et al.; licensee BioMed Central Ltd. Background: During mammalian pre-implantation embryonic development dramatic and orchestrated changes occur in gene transcription. The identification of the complete changes has not been possible until the development of the Next Generation Sequencing Technology.Results: Here we report comprehensive transcriptome dynamics of single matured bovine oocytes and pre-implantation embryos developed in vivo. Surprisingly, more than half of the estimated 22,000 bovine genes, 11,488 to 12,729 involved in more than 100 pathways, is expressed in oocytes and early embryos. Despite the similarity in the total numbers of genes expressed across stages, the nature of …

Relative Importance Of Environmental, Geographic, And Spatial Variables On Zooplankton Metacommunities, Tad Dallas, John M. Drake

Faculty Publications

© 2014 Dallas and Drake. Understanding the factors responsible for structuring ecological communities is a central goal in community ecology. Previous work has focused on determining the relative roles of two classes of variables (e.g., spatial and environmental) on community composition. However, this approach may ignore the disproportionate impact of variables within classes, and is often confounded by spatial autocorrelation leading to collinearity among variables of different classes. Here, we combine pattern-based metacommunity and machine learning analyses to characterize metacommunity structure of zooplankton from lakes in the northeast United States and to identify environmental, spatial, and geographic covariates associated with …

The Association Of The Vanin-1 N131s Variant With Blood Pressure Is Mediated By Endoplasmic Reticulum-Associated Degradation And Loss Of Function, Ya Juan Wang, Bamidele O. Tayo, Anupam Bandyopadhyay, Heming Wang, Tao Feng, Nora Franceschini, Hua Tang, Jianmin Gao, Yun Ju Sung, Robert C. Elston, Scott M. Williams, Richard S. Cooper, Ting Wei Mu, Xiaofeng Zhu, Daniel Levy

Faculty Publications

High blood pressure (BP) is the most common cardiovascular risk factor worldwide and a major contributor to heart disease and stroke. We previously discovered a BP-associated missense SNP (single nucleotide polymorphism)–rs2272996–in the gene encoding vanin-1, a glycosylphosphatidylinositol (GPI)-anchored membrane pantetheinase. In the present study, we first replicated the association of rs2272996 and BP traits with a total sample size of nearly 30,000 individuals from the Continental Origins and Genetic Epidemiology Network (COGENT) of African Americans (P = 0.01). This association was further validated using patient plasma samples; we observed that the N131S mutation is associated with significantly lower plasma vanin-1 …

Effects Of Oil On Terrestrial Vertebrates: Predicting Impacts Of The Macondo Blowout, Christine M.Bergeon Burns, Jill A. Olin, Philip C. Stouffer, Sabrina S. Taylor, Stefan Woltmann

Faculty Publications

In addition to external oiling, marine oil spills may affect vertebrate animals through degradation of habitat; alterations in food web structure; and contamination of resources by toxic compounds, including polycyclic aromatic hydrocarbons. These processes are not well understood for vertebrates breeding and foraging in terrestrial ecosystems affected by oil, such as coastal marshes that were heavily oiled following the 2010 Macondo oil spill. Here, we review what is known about the ecological and physiological effects of oil exposure on vertebrates in general. We then apply these concepts to salt-marsh vertebrates, with special reference to our ongoing monitoring of impacts and …

Tectonics, Topography, And River System Transition In East Tibet: Insights From The Sedimentary Record In Taiwan, Qing Lan, Yi Yan, Chi Yue Huang, Peter D. Clift, Xuejie Li, Wenhuang Chen, Xingchang Zhang, Mengming Yu

Faculty Publications

©2014. American Geophysical Union. The Cenozoic in East Asia is marked by major changes in tectonics, landscapes, and river systems, although the timing and nature of such changes remains disputed. We investigate the geochemistry and neodymium isotope character of Cenozoic mudstones spanning the breakup unconformity in the Western Foothills of Taiwan in order to constrain erosion and drainage development in southern China during the opening of the South China Sea. The La/Lu, Eu/Eu∗, Th/Sc, Th/La, Cr/Th, and eNd values in these rocks show an abrupt change between ∼31 and 25 Ma. Generally the higher eNd values in sediments deposited prior …

Improving The Efficiency Of Electrical Stimulation Activities After Spinal Cord Injury, David Dolbow, William R. Holcomb, Ashraf Gorgey

Faculty Publications

In order to enhance spinal cord injury (SCI) rehabilitation programs using neuromuscular electrical stimulation (NMES) and functional electrical stimulation (FES) it is important to examine the manner in which muscle fibers are recruited and the dose–response relationship. A review of the literature suggests that premature force decline and early fatigue with NMES and FES activities may be alleviated with decreased current frequency and increased current intensity. Dose–response relationships with NMES and FES are dependent on the goals of interest as reversing muscle atrophy can be achieved with activities 2–3 times per week for 6 or more weeks while increasing bone …

Influence Of Resource Levels, Organic Compounds And Laboratory Colonization On Interspecific Competition Between The Asian Tiger Mosquito Aedes Albopictus (Stegomyia Albopicta) And The Southern House Mosquito Culex Quinquefasciatus, D.W. Allgood, Donald A. Yee

Faculty Publications

The mosquitoes Aedes albopictus (Stegomyia albopicta) (Skuse) and Culex quinquefasciatus (Say) (Diptera: Culicidae) are common inhabitants of tyres and other artificial containers, which constitute important peridomestic mosquito breeding habitats. We tested the hypotheses that interspecific resource competition between the larvae of these species is asymmetrical, that the concentration of chemicals associated with decomposing detritus affects the competitive outcomes of these species, and that wild and colonized strains of Cx. quinquefasciatus are affected differently by competition with Ae. albopictus. We conducted two laboratory competition experiments wherein we measured survivorship and estimated population growth (λ′) in both species under …

Using Non-Environmental Law To Accomplish Environmental Objectives, Todd S. Aagaard

Faculty Publications

The current prolonged period of congressional impasse on environmental issues, in which symbolic ideological skirmishes have largely supplanted constructive engagement, makes clear that Congress is unlikely to generate progress on environmental issues any time soon. In response to this legislative stalemate, some environmental law scholars have advocated for giving the Environmental Protection Agency enhanced capability to take administrative action under the authority of existing environmental statutes.

Without disagreeing with those arguments, this article contends that we also need strategies for environmental law that transcend, not just adapt, the canonical environmental statutes that have been the field’s mainstay since the early …

Effects Of Caste On The Expression Of Genes Associated With Septic Injury And Xenobiotic Exposure In The Formosan Subterranean Termite, Claudia Husseneder, Dawn M. Simms

Faculty Publications

As social insects, termites live in densely populated colonies with specialized castes under conditions conducive to microbial growth and transmission. Furthermore, termites are exposed to xenobiotics in soil and their lignocellulose diet. Therefore, termites are valuable models for studying gene expression involved in response to septic injury, immunity and detoxification in relation to caste membership. In this study, workers and soldiers of the Formosan subterranean termite, Coptotermes formosanus, were challenged by bacterial injection or by no-choice feeding with a sublethal concentration (0.5%) of phenobarbital. Constitutive and induced expression of six putative immune response genes (two encoding for lectin-like proteins, one …

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 …

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 …

Getting Into The Meat Of The Word Of Wisdom, A. Jane Birch

Faculty Publications

Doctrine & Covenants Section 89 is known as the "health code" for members of The Church of Jesus Christ of Latter-day Saints. In verse 13 of this scripture, the Lord states, “it is pleasing unto me that they [flesh of beasts and fowls of the air] should not be used, only in times of winter, or of cold, or famine” (D&C 89:13). Judging from the variety of interpretations this single verse has inspired, it would appear to be deeply enigmatic. Interestingly, most interpretations have been put forward with little supporting evidence. This article is the first comprehensive analysis of the …

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.

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. …

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 …
