Precolonized Human Commensal Escherichia Coli Strains Serve As A Barrier To E. Coli O157:H7 Growth In The Streptomycin-Treated Mouse Intestine, Mary P. Leatham, Swati Banerjee, Steven M. Autieri, Regino Mercado-Lubo, Tyrrell Conway, Paul S. Cohen

Cell and Molecular Biology Faculty Publications

Different Escherichia coli strains generally have the same metabolic capacity for growth on sugars in vitro, but they appear to use different sugars in the streptomycin-treated mouse intestine (Fabich et al., Infect. Immun. 76:1143-1152, 2008). Here, mice were precolonized with any of three human commensal strains (E. coli MG1655, E. coli HS, or E. coli Nissle 1917) and 10 days later were fed 10⁵ CFU of the same strains. While each precolonized strain nearly eliminated its isogenic strain, confirming that colonization resistance can be modeled in mice, each allowed growth of the other commensal strains to higher numbers, …

Functional Interaction Between The Fanconi Anemia D2 Protein And Proliferating Cell Nuclear Antigen (Pcna) Via A Conserved Putative Pcna Interaction Motif, Niall G. Howlett, Julie A. Harney, Meghan A. Rego, Frederick W. Kolling Iv, Thomas W. Glover

Cell and Molecular Biology Faculty Publications

Fanconi Anemia (FA) is a rare recessive disease characterized by congenital abnormalities, bone marrow failure, and cancer susceptibility. The FA proteins and the familial breast cancer susceptibility gene products, BRCA1 and FANCD1/BRCA2, function cooperatively in the FA-BRCA pathway to repair damaged DNA and to prevent cellular transformation. Activation of this pathway occurs via the mono-ubiquitination of the FANCD2 protein, targeting it to nuclear foci where it co-localizes with FANCD1/BRCA2, RAD51, and PCNA. The regulation of the mono-ubiquitination of FANCD2, as well as its function in DNA repair remain poorly understood. In this study, we have further characterized the interaction between …

Reforming Section 10 And The Habitat Conservation Plan Program, David A. Dana

Faculty Working Papers

This Chapter in a forthcoming book to be published by AEI (edited by Jonathan Adler) provides a framework for HCP reform. The Chapter first briefly reviews the history of HCP regulations and guidance, and what we know about HCPs in practice (which is limited). It offers a range of reforms to address problems in the current HCP approach, including requirements that the Services assemble a better database regarding current HCPs and report to Congress on the program periodically; greater reliance on programmatic regulations adopted after notice and comment; development of guidelines for assessing the likely or possible environmental impacts of …

The Effect Of Exercise On Alzheimer’S Disease, Benjamin Korman

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease (AD) is a progressive neurodegenerative disease, from which there is no recovery. It begins with impaired memory and judgement and progresses to the point where those affected can no longer care themselves. Although the cause of AD is unknown, two significant abnormalities occur in the brain of its victims: neurofibrillary tangles and amyloid plaques. It has been well established that exercise improves mood and general well-being, however this paper will focus on the effect of exercise on AD. It will show that exercise can improve physical functioning of an individual with AD, however more importantly it will focus …

Demographics Of A Geographically-Isolated Population Of Threatened Salamander (Caudata: Ambystomatidae) In Central Illinois, Stephen J. Mullin, Sarabeth Klueh

Faculty Research & Creative Activity

Amphibian populations that use small isolated wetlands are often small in size, susceptible to stochastic extinction processes, and have little to no contact with other populations. One can ascertain the persistence of such populations only by obtaining data that allow the prediction of future changes in population’s size, and propensity to achieve a sustainable number of individuals. The number of metamorphosing larvae leaving a pond predicts the viability of a salamander population, and thus, the number recruited into the terrestrial adult population. The Jefferson Salamander, Ambystoma jeffersonianum, is a listed threatened species in Illinois, occurring at fewer than 15 ponds …

Thermoregulation Of Male Elaphe Spiloides In An Agriculturally-Fragmented Forest In Illinois, C. Drew Foster, Sarabeth Kleuh, Stephen J. Mullin

Faculty Research & Creative Activity

Anthropogenic forest fragmentation increases the amount of edge habitat. Although edges are harsh environments for many native species, ratsnakes often prefer this habitat. We examined thermoregulatory effectiveness of Central Ratsnakes (Elaphe spiloides) using forest edges preferentially to determine if edge preference is driven by increased thermoregulatory efficiencies. Six male subjects were located every 1-2 days using radio-telemetry and temperature sensitive transmitters. Subjects did not thermoregulate more efficiently in edges than in forest. Snakes were thermoconformers in both habitat types suggesting edge preference might be driven by other factors.

Vegetative Anatomy And Systematics Of Triphorinae (Orchidaceae), Barbara S. Carlsward, William Louis Stern

Faculty Research & Creative Activity

Triphorinae represents a group of three anatomically simple genera, the structural features of which are unspecialized. The anomocytic stomatal pattern occurs in all genera; it predominates in Triphora . A foliar hypodermis, sclerenchyma, fibre bundles and stegmata are absent. The mesophyll is homogeneous. The exodermal and endodermal cells in the roots are entirely thin-walled and tilosomes are absent. However, there are anatomical modifications that appear to be unique: root hairs in Monophyllorchis are borne on velamenal buttresses and, in Psilochilus , they arise endogenously. In the root vascular system of Psilochilus , the metaxylem occurs as a circumferential band. The …

Sucrose Phosphate Synthase Expression Influences Poplar Phenology, Thomas Canam, Ji-Young Park, Kyu-Young Kang, Faride Unda, Shawn Mansfield

Faculty Research & Creative Activity

The objective of this study was to manipulate the intracellular pools of sucrose, and investigate its role in regulating plant growth, phenology (leaf senescence and bud break) and fibre development. This objective was achieved by differentially expressing an Arabidopsis (Arabidopsis thaliana L. Heynh.) sucrose phosphate synthase (SPS) gene in hybrid poplar (Populus alba · Populus grandidentata Michx.), a model system for tree biology with substantial industrial relevance in the context of short rotation forestry and a target bioenergy crop. Phenotypic differences were evident in the transgenic trees, as both the timing of bud flush and leaf senescence were altered compared …

Botany At Eastern Illinois University, Marissa Jernegan, Nancy Coutant, Janice Coons

Faculty Research & Creative Activity

Eastern Illinois University was established in 1899, and from its beginning the importance of the botanical sciences was recognized. Two terms of botany were required for the four year program. Dr. Otis W. Caldwell, a botanist, was one of the original faculty members. He taught all of the biology courses and initiated the acquisition of a greenhouse. Caldwell was the first in a series of talented and dedicated botany professors including Edgar N. Transeau, Ernest L. Stover, Hiram F. Thut and John E. Ebinger. These and many other professors incorporated a field component into almost all classes. This dedication to …

Salmonella Enterica Serovar Typhimurium Mutants Unable To Convert Malate To Pyruvate And Oxaloacetate Are Avirulent And Immunogenic In Balb/C Mice, Regino Mercado-Lubo, Mary P. Leatham, Tyrrell Conway, Paul S. Cohen

Cell and Molecular Biology Faculty Publications

Previously, we showed that the Salmonella enterica serovar Typhimurium SR-11 tricarboxylic acid (TCA) cycle must operate as a complete cycle for full virulence after oral infection of BALB/c mice (M. Tchawa Yimga, M. P. Leatham, J. H. Allen, D. C. Laux, T. Conway, and P. S. Cohen, Infect. Immun. 74:1130-1140, 2006). In the same study, we showed that for full virulence, malate must be converted to both oxaloacetate and pyruvate. Moreover, it was recently demonstrated that blocking conversion of succinyl-coenzyme A to succinate attenuates serovar Typhimurium SR-11 but does not make it avirulent; however, blocking conversion of succinate to …

Identification Of N-Terminal Lobe Motifs That Determine The Kinase Activity Of The Catalytic Domains And Regulatory Strategies Of Src And Csk Protein Tyrosine Kinases, Kezhen Huang, Yue-Hao Wang, Alex Brown, Gongqin Sun

Cell and Molecular Biology Faculty Publications

Csk and Src protein tyrosine kinases are structurally homologous but use opposite regulatory strategies. The isolated catalytic domain of Csk is intrinsically inactive and is activated by interactions with the regulatory Src homology 3 (SH3) and SH2 domains, while the isolated catalytic domain of Src is intrinsically active and is suppressed by interactions with the regulatory SH3 and SH2 domains. The structural basis for why one isolated catalytic domain is intrinsically active while the other is inactive is not clear. In this study, we identified structural elements in the N-terminal lobe of the catalytic domain that render the Src catalytic …

Development And Characterization Of A High Density Snp Genotyping Assay For Cattle, Lakshmi K. Matukumalli, Cynthia T. Lawley, Robert D. Schnabel, Jeremy F. Taylor, Mark F. Allan, Michael P. Heaton, Jeff O'Connell, Stephen S. Moore, Timothy P. L. Smith, Tad S. Sonstegard, Curtis P. Van Tassell

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The success of genome-wide association (GWA) studies for the detection of sequence variation affecting complex traits in human has spurred interest in the use of large-scale high-density single nucleotide polymorphism (SNP) genotyping for the identification of quantitative trait loci (QTL) and for marker-assisted selection in model and agricultural species. A costeffective and efficient approach for the development of a custom genotyping assay interrogating 54,001 SNP loci to support GWA applications in cattle is described. A novel algorithm for achieving a compressed inter-marker interval distribution proved remarkably successful, with median interval of 37 kb and maximum predicted gap of ,350 kb. …

Environmental Stress And Genetics Influence Night-Time Leaf Conductance In The C4 Grass Distichlis Spicata, Rebecca E. Drenovsky, Mairgareth A. Christman, Jeremy J. James, James H. Richards

Biology

Growing awareness of night-time leaf conductance (gnight) in many species, as well as genetic variation in gnight within several species, has raised questions about how genetic variation and environmental stress interact to influence the magnitude of gnight. The objective of this study was to investigate how genotype salt tolerance and salinity stress affect gnight for saltgrass [Distichlis spicata (L.) Greene]. Across genotypes and treatments, night-time water loss rates were 5–20% of daytime rates. Despite growth declining 37–87% in the high salinity treatments (300 mM and 600 mM NaCl), neither treatment had any effect on gnight in four of the six …
