Greater Diversity Of Shiga Toxin-Encoding Bacteriophage Insertion Sites Among Escherichia Coli O157:H7 Isolates From Cattle Than In Those From Humans, Thomas E. Besser, Nurmohammad Shaikh, Nicholas J. Holt, Phillip I. Tarr, Michael E. Konkel, Preeti Malik-Kale, Coilin W. Walsh, Thomas S. Whittam, James L. Bono

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

E. coli O157:H7, a zoonotic human pathogen for which domestic cattle are a reservoir host, produces a Shiga toxin(s) (Stx) encoded by bacteriophages. Chromosomal insertion sites of these bacteriophages define three principal genotypes (clusters 1 to 3) among clinical isolates of E. coliO157:H7. Stx-encoding bacteriophage insertion site genotypes of 282 clinical and 80 bovine isolates were evaluated. A total of 268 (95.0%) of the clinical isolates, but only 41 (51.3%) of the bovine isolates, belonged to cluster 1, 2, or 3 (P < 0.001). Thirteen additional genotypes were identified in isolates from both cattle and humans (four genotypes), from only cattle (seven genotypes), or from only humans (two genotypes). Two other markers previously associated with isolates from cattle or with clinical isolates showed similar associations with genotype groups within bovine isolates; the tir allele sp-1 and the Q_933W allele were under- and overrepresented, respectively, among cluster 1 to …

Somatic Excision Demonstrates That C-Jun Induces Cellular Migration And Invasion Through Induction Of Stem Cell Factor, Sanjay Katiyar, Xuanmao Jiao, Erwin Wagner, Michael P. Lisanti, Richard G. Pestell

Department of Cancer Biology Faculty Papers

Cancer cells arise through sequential acquisition of mutations in tumor suppressors and oncogenes. c-Jun, a critical component of the AP-1 complex, is frequently overexpressed in diverse tumor types and has been implicated in promoting cellular proliferation, migration, and angiogenesis. Functional analysis of candidate genetic targets using germ line deletion in murine models can be compromised through compensatory mechanisms. As germ line deletion of c-jun induces embryonic lethality, somatic deletion of the c-jun gene was conducted using floxed c-jun (c-jun^f/f) conditional knockout mice. c-jun-deleted cells showed increased cellular adhesion, stress fiber formation, and reduced cellular migration. The reduced migratory …

Hyperthermic Effects Of Gold Nanorods On Tumor Cells, Terry B. Huff, Ling Tong, Matthew N. Hansen, Ji-Xin Cheng, Alexander Wei

Other Nanotechnology Publications

Plasmon-resonant gold nanorods, which have large absorption cross sections at near-infrared frequencies, are excellent candidates as multifunctional agents for image-guided therapies based on localized hyperthermia. The controlled modification of the surface chemistry of the nanorods is of critical importance, as issues of cell-specific targeting and nonspecific uptake must be addressed prior to clinical evaluation. Nanorods coated with cetyltrimethylammonium bromide (a cationic surfactant used in nanorod synthesis) are internalized within hours into KB cells by a nonspecific uptake pathway, whereas the careful removal of cetyltrimethylammonium bromide from nanorods functionalized with folate results in their accumulation on the cell surface over the …

Cephalalgiaphobia: A Possible Specific Phobia Of Illness., Mario F P Peres, Juliane P P Mercante, Vera Z Guendler, Felipe Corchs, Marcio A Bernik, Eliova Zukerman, Stephen Silberstein

Department of Jefferson Headache Center Papers and Presentations

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild …

Water In Beaver Dam Wash And Lytle Preserve, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

This short work is derived from a manuscript prepared for presentation in a water adjudication hearing, following a proposal to pipe water from wells in Beaver Dam Wash for transfer across state lines to be used for culinary and other purposes in Mesquite, Nevada. The Wash is estimated to yield 2000 acre feet of water annually, mostly as subsurface flow, at the Arizona line. About a third of that amount is already appropriated by users along the Wash in Utah, but there are applications pending for more than 100,000 acre feet in Utah. Thus, the Wash is already oversubscribed by …

Physiological, Ecological, And Phylogenetic Characterization Of Stappia, A Marine Co-Oxidizing Bacterial Genus, Carolyn F. Weber, Gary M. King

Faculty Publications

Bacteria play a major role in marine CO cycling, yet very little is known about the microbes involved. Thirteen CO-oxidizing Stappia isolates obtained from existing cultures, macroalgae, or surf samples representing geographically and ecologically diverse habitats were characterized using biochemical, physiological, and phylogenetic approaches. All isolates were aerobic chemoorganotrophs that oxidized CO at elevated (1,000 ppm) and ambient-to-subambient concentrations (<0.3 ppm). All contained the form I (OMP) coxL gene for aerobic CO dehydrogenase and also the form II (BMS) putative coxL gene. In addition, some strains possessed cbbL, the large subunit gene for ribulose-1,5-bisphosphate carboxylase/oxygenase, suggesting the possibility of lithotrophic or mixotrophic metabolism. All isolates used a wide range of sugars, organic acids, amino acids, and aromatics for growth and grew at salinities from 5 to 45 ppt. All but one isolate denitrified or respired nitrate. Phylogenetic analyses based on 16S rRNA gene sequences indicated that several isolates could not be distinguished from Stappia aggregata and contributed to a widely distributed species complex. Four isolates (of strains GA15, HI, MIO, and M4) were phylogenetically distinct from validly described Stappia species and closely related genera (e.g., Ahrensia, Pannonibacter, Pseudovibrio, and Roseibium). Substrate utilization profiles, enzymatic activity, and membrane lipid composition further distinguished these isolates and supported their designations as new Stappia species. The observed metabolic versatility of Stappia likely accounts for its cosmopolitan distribution and its ability to contribute to CO cycling as well as other important biogeochemical cycles.

Stratification Of Southern Georgia Streams For Rapid Bioassessment Focusing On Differences In Structure And Function Of Black Water And Clear Water Streams, Salini Pradeep Pillai

Theses and Dissertations

As part of a rapid bioassessment project for the state of Georgia, relatively unimpaired reference streams and impaired sites were sampled for biological, chemical and physical parameters, and macroinvertebrates were identified. The metrics, biological, physical and chemical metrics, were selected using Ecological Data Application System Version 3.3.2k (EDAS). Discrimination efficiency and correlations were performed to determine the best metrics that separated impaired streams from reference streams and later on to form the index of stream water quality. Principal components analysis of the selected metrics showed that some of the blackwater reference streams and clearwater reference streams are randomly placed over …

Effects Of Joint Space Use And Group Membership On Contact Rates Among White-Tailed Deer, Eric M. Schauber, Daniel J. Storm, Clayton K. Nielsen

Publications

Establishment and spread of infectious diseases are controlled by the frequency of contacts among hosts. Although managers can estimate transmission coefficients from the relationship between disease prevalence and age or time, they may wish to quantify or compare contact rates before a disease is established or while it is at very low prevalence. Our objectives were to quantify direct and indirect contacts rates among white-tailed deer (Odocoileus virginianus) and to compare these measures of contact rate with simpler measures of joint space use. We deployed Global Positioning System (GPS) collars on 23 deer near Carbondale, Illinois, USA, from …

School Improvement In Multi-Grade Situation (Sims): An Innovation Of The Pdcc, Jalal Wali Khan

Book Chapters / Conference Papers

Professional Development Center, Chitral (PDCC), since its establishment in Chitral, is committed to work with its partner education providers for the improvement of quality of teaching and learning in schools. PDCC believes that effective teaching and learning in primary, acts as a foundation stone for higher education, but currently it does not happen in majority of our primary schools. Multi-grade situation in primary schools is one of the many reasons of low quality education. School Improvement in Multi-grade Situation (SIMS) was piloted in five schools aiming to improve the current Multi-grade Teaching (MGT) situation in schools. This study intended to …

Assessing Among-Locus Variation In The Inference Of Seed Plant Phylogeny, J. Gordon Burleigh, Sarah Mathews

Faculty Publications

Large multilocus analyses can greatly reduce sampling error in phylogenetic estimates and help resolve difficult phylogenetic questions. Yet conventional multilocus analyses may be confounded by variation in the phylogenetic signal or processes of evolution among loci. We used nonparametric bootstrapping methods to examine locus-specific variation within a 12-locus seed plant data set and to examine the effects of this variation on estimates of seed plant phylogeny. The observed maximum likelihood and maximum parsimony bootstrap support from phylogenetic analyses of sites within single loci often notably differs from the bootstrap support obtained by sampling an equal number of sites from the …

Generation And Characterization Of Rabbit Embryonic Stem Cells, Shufen Wang, Xianghui Tang, Yuyu Niu, Hongwei Chen, Bin Li, Tianqing Li, Xiuzhen Zhang, Zhixin Hu, Qi Zhou, Weizhi Ji

Faculty Publications

We described the derivation of four stable pluripotent rabbit embryonic stem cell (ESC) lines, one (RF) from blastocysts fertilized in vivo and cultured in vitro and three (RP01, RP02, and RP03) from parthenogenetic blastocysts. These ESC lines have been cultivated for extended periods (RF >1 year, RP01 >8 months, RP02 >8 months, and RP03 >6 months) in vitro while maintaining expression of pluripotent ESC markers and a normal XY or XX karyotype. The ESCs from all lines expressed alkaline phosphatase, transcription factor Oct-4, stage-specific embryonic antigens (SSEA-1, SSEA-3, and SSEA-4), and the tumor-related antigens (TRA-1-60 and TRA-1-81). Similar to human …

People-Centric Urban Sensing: Security Challenges For The New Paradigm, Peter Johnson, Apu Kapadia, David Kotz, Nikos Triandopoulos

Computer Science Technical Reports

We study the security challenges that arise in \emph{people-centric urban sensing}, a new sensor-networking paradigm that leverages humans as part of the sensing infrastructure. Most prior work on sensor networks has focused on collecting and processing ephemeral data about the environment using a static topology and an application-aware infrastructure. People-centric urban sensing, however, involves collecting, storing, processing and fusing large volumes of data related to every-day human activities. Sensing is performed in a highly dynamic and mobile environment, and supports (among other things) pervasive computing applications that are focused on enhancing the user's experience. In such a setting, where humans …

The Takings Clause, Version 2005: The Legal Process Of Constitutional Property Rights, Mark Fenster

UF Law Faculty Publications

The search for coherence in takings jurisprudence has resulted in a multitude of theories but no consensus. Each theory -- whether based on conceptions of common law property rights or constitutional conceptions of justice, or based on utility, natural law, or communitarian or republican conceptions of the good --offers significant insight into the vexing legal, political, and normative issues that judicial enforcement of the Takings Clause raises. But no single theory of property or of constitutional limits on state regulation and expropriation has proven capable either of satisfactorily rationalizing existing takings law or of persuading the courts or the theory's …
