Fas And Cfl Forms Of Verbal Fluency Differ In Difficulty: A Meta-Analytic Study, Danielle Barry

UCHC Articles - Research

The Controlled Oral Word Association (COWA) Test is a brief and sensitive measure of executive cognitive dysfunction. There are two commonly used forms of the test, one using the letters F, A, and S, and the other using C, F, and L. This study examines the relative difficulty of the two forms using a meta-analytic approach that includes multiple samples of normal individuals. The effects of age, education, gender composition, exclusion criteria, and age of study are also examined. Results indicate that the CFL form of the test is more difficult and that age, education, and the use of strict …

Biochemical Applications Of Ultrathin Films Of Enzymes, Polyions And Dna, James F. Rusling, Dominic O. Hull, Eli G. Hvastkovs, John B. Schenkman

UCHC Articles - Research

This feature article summarizes recent applications of ultrathin films of enzymes and DNA assembled layer-by-layer (LbL). Using examples mainly from our own research, we focus on systems developed for biocatalysis and biosensors for toxicity screening. Enzyme–poly(l-lysine) (PLL) films, especially when stabilized by crosslinking, can be used for biocatalysis at unprecedented high temperatures or in acidic or basic solutions on electrodes or sub-micron sized beads. Such films have bright prospects for chiral synthesis and biofuel cells. Excellent bioactivity and retention of enzyme structure in these films facilitates their use in detailed kinetic studies. Biosensors and arrays employing DNA–enzyme films show great …

Management Of Oral Mucositis In Patients With Cancer, Rajesh V. Lalla, Douglas E. Peterson

UCHC Articles - Research

Oral mucositis refers to erythematous and ulcerative lesions of the oral mucosa observed in patients with cancer being treated with chemotherapy, and/or with radiation therapy to fields involving the oral cavity. Lesions of oral mucositis are often very painful and compromise nutrition and oral hygiene as well as increase risk for local and systemic infection. Mucositis can also involve other areas of the alimentary tract; for example, gastrointestinal (GI) mucositis can manifest as diarrhea. Thus, mucositis is a highly significant and sometimes dose-limiting complication of cancer therapy.

Phagocytosis Of Borrelia Burgdorferi, The Lyme Disease Spirochete, Potentiates Innate Immune Activation And Induces Apoptosis In Human Monocytes, Adriana R. Cruz, Meagan W. Moore, Carson J. La Vake, Christian H. Eggers, Juan C. Salazar, Justin D. Radolf

UCHC Articles - Research

We have previously demonstrated that phagocytosed Borrelia burgdorferi induces activation programs in human peripheral blood mononuclear cells that differ qualitatively and quantitatively from those evoked by equivalent lipoprotein-rich lysates. Here we report that ingested B. burgdorferi induces significantly greater transcription of proinflammatory cytokine genes than do lysates and that live B. burgdorferi, but not B. burgdorferi lysate, is avidly internalized by monocytes, where the bacteria are completely degraded within phagolysosomes. In the course of these experiments, we discovered that live B. burgdorferi also induced a dose-dependent decrease in monocytes but not a decrease in dendritic cells or T cells …

Hedonic Adaptation And The Settlement Of Civil Lawsuits (With J. Bronsteen & J. Masur), Christopher J. Buccafusco

All Faculty Scholarship

This paper examines the burgeoning psychological literature on happiness and hedonic adaptation (a person's capacity to preserve or recapture her level of happiness by adjusting to changed circumstances), bringing this literature to bear on a previously overlooked aspect of the civil litigation process: the probability of pre-trial settlement. The glacial pace of civil litigation is commonly thought of as a regrettable source of costs to the relevant parties. Even relatively straightforward personal injury lawsuits can last for as long as two years, delaying the arrival of necessary redress to the tort victim and forcing the litigants to expend ever greater …

Morphine Exacerbates Hiv-1 Tat-Induced Cytokine Production In Astrocytes Through Convergent Effects On [Ca2+]I, Nf-Κb Trafficking And Transcription, Nazira El-Hage, Annadora J. Bruce-Keller, Tatiana Yakovleva, Igor Bazov, Georgy Bakalkin, Pamela E. Knapp, Kurt F. Hauser

Pharmacology and Toxicology Publications

Astroglia are key cellular sites where opiate drug signals converge with the proinflammatory effects of HIV-1 Tat signals to exacerbate HIV encephalitis. Despite this understanding, the molecular sites of convergence driving opiate-accelerated neuropathogenesis have not been deciphered. We therefore explored potential points of interaction between the signaling pathways initiated by HIV-1 Tat and opioids in striatal astrocytes. Profiling studies screening 152 transcription factors indicated that the nuclear factor-kappa B (NF-κB) subunit, c-Rel, was a likely candidate for Tat or Tat plus opiate-induced increases in cytokine and chemokine production by astrocytes. Pretreatment with the NF-κB inhibitor parthenolide provided evidence that Tat±morphine-induced …

Long Lasting Synchronization Of Calcium Oscillations By Cholinergic Stimulation In Isolated Pancreatic Islets, Min Zhang, Bernard Fendler, Bradford Peercy, Pranay Goel, Richard Bertram, Arthur Sherman, Leslie Satin

Pharmacology and Toxicology Publications

Abstract

Individual mouse pancreatic islets exhibit oscillations in [Ca²⁺]_i and insulin secretion in response to glucose in vitro, but how the oscillations of a million islets are coordinated within the human pancreas in vivo is unclear. Islet to islet synchronization is necessary, however, for the pancreas to produce regular pulses of insulin. To determine whether neurohormone release within the pancreas might play a role in coordinating islet activity, [Ca²⁺]_i changes in 4–6 isolated mouse islets were simultaneously monitored before and after a transient pulse of a putative synchronizing agent. The degree of synchronicity was …

Racism And The Political Romance Of The Browning Of America, Ronald Sundstrom

Philosophy

The browning of America promises the bodily, social, and political transfor- mation of the United States, and as with all ethno-racial threats—or promises of deliverance—browning operates through the private, intimate arenas of love, sexuality, gender, family, and friendship. As a demographic idea, the “browning of America” gathers together Native Americans, African Ameri- cans, Latinos, Asian Americans, and Americans with a multiracial identity, as well as non-white immigrants. In popular culture, however, it primarily con- notes the expanding population of Latinos, and Mexican and Latin American immigrants. Secondarily, it includes the growing social and political presence of multiracial Americans, those who …

Aerial Census Techniques For Whooping Cranes On The Texas Coast, Thomas V. Stehn, Thomas E. Taylor

Proceedings of the North American Crane Workshop

The U.S. Fish and Wildlife Service, using aerial surveys, regularly monitors the whooping crane (Grus americana) population wintering along the Texas coast. These regular census flights began in 1950 and have produced a long-term data set on the growth of a small population of endangered birds. This paper describes the specific methodology used by the authors during census flights.

Eco-Geomorphic Implications Of Hillslope Aspect: Inferences From Analysis Of Landscape Morphology In Central New Mexico, Erkan Istanbulluoglu, Omer Yetemen, Enrique R. Vivoni, Hugo A. Gutierrez-Jurado, Rafael L. Bras

School of Natural Resources: Faculty Publications

We investigate the influence of hillslope aspect on landscape morphology in central New Mexico, where differences in soils, vegetation, and landforms are observed between mesic north-facing and xeric south-facing slopes. Slope–area and curvature–area relations, derived from a Digital Elevation Model (DEM), are used to characterize the opposing hillslope morphologies. In all geologies and elevation ranges studied, topographic data reveal significantly steeper slopes in north-facing aspects, and shallower slopes in south-facing aspects. North-facing slope curvatures are also greater than south-facing curvatures. Using a conceptual slope-area model, we suggest that for a given drainage area, steeper north-facing slopes imply lower soil erodibility. …

Interpretation And Evaluation Of Combined Measurement Techniques For Soil Co2 Efflux: Discrete Surface Chambers And Continuous Soil Co2 Concentration Probes, Diego Andrés Riveros-Iregui, Brian L. Mcglynn, Howard E. Epstein, Daniel L. Welsch

School of Natural Resources: Faculty Publications

Soil CO₂ efflux is a large respiratory flux from terrestrial ecosystems and a critical component of the global carbon (C) cycle. Lack of process understanding of the spatiotemporal controls on soil CO₂ efflux limits our ability to extrapolate from fluxes measured at point scales to scales useful for corroboration with other ecosystem level measures of C exchange. Additional complications are introduced by the effects of soil water content seasonality and rainfall on the performance of measurement techniques. In this paper we present measurements of soil CO₂ efflux made at two contrasting sites within a characteristic subalpine forest …

The Risk Of Flawed Inference In Evolutionary Studies When Detectability Is Less Than One, Olivier Gimenez, Anne Viallefont, Anne Charmantier, Roger Pradel, Emmanuelle Cam, Charles R. Brown, Mark D. Anderson, Mary Bomberger Brown, Rita Covas, Jean-Michel Gaillard2

School of Natural Resources: Faculty Publications

Addressing evolutionary questions in the wild remains a challenge. It is best done by monitoring organisms from birth to death, which is very difficult in part because individuals may or may not be resighted or recaptured. Although the issue of uncertain detection has long been acknowledged in ecology and conservation biology, in evolutionary studies of wild populations it is often assumed that detectability is perfect. We argue that this assumption may lead to flawed inference. We demonstrate that the form of natural selection acting on body mass of sociable weavers is altered and that the rate of senescence of roe …

Peregrine Falcon Survival And Resighting Frequencies On The Washington Coast, 1995–2003, Daniel E. Varland, Larkin A. Powell, Mary Kay Kenney, Tracy Fleming

School of Natural Resources: Faculty Publications

We estimated survival for Peregrine Falcons (Falco peregrinus) in beach-dune habitat along the Washington coast. We captured and color-banded 76 Peregrine Falcons during 438 surveys by vehicle on three coastal beaches in Washington from January 1995 to May 2003. We captured 45 females and 31 males; 68% (52) were ,1 yr old and 32% (24) were $1 yr old. Based primarily on photographs (N 5 72) showing plumage coloration, 76% (N 5 55) of the individuals captured were F. p. pealei, 7% (N 5 5) were F. p. anatum, 3%(N 5 2) were F. p. tundrius, and …

An Ecologist Struggles With The Problem Of Evil: Why Aldo Leopold And Baby Meadowlarks Argue Against An All-Powerful God, Larkin A. Powell

School of Natural Resources: Faculty Publications

“A theology squares with validated materials. It cannot do otherwise.”1 —R. A. Cheville

I am a wildlife population ecologist; I study factors that cause populations of animals to increase or decrease in number. Ecologists focus their studies on living and nonliving components of ecosystems. In this paper, I describe how my career as a scientist and ecologist has influenced my current theology. And I will describe how my theology has been shaped by my experiences with baby meadowlarks and the writings of Aldo Leopold. Roy Cheville wrote in a 1971 letter to a “good friend”: “Today people of inquiring mind …

Fish Distributions And Nutrient Cycling In Streams: Can Fish Create Biogeochemical Hotspots?, Peter B. Mcintyre, Alexander S. Flecker, Michael J. Vanni, James M. Hood, Brad W. Taylor, Steven A. Thomas

School of Natural Resources: Faculty Publications

Rates of biogeochemical processes often vary widely in space and time, and characterizing this variation is critical for understanding ecosystem functioning. In streams, spatial hotspots of nutrient transformations are generally attributed to physical and microbial processes. Here we examine the potential for heterogeneous distributions of fish to generate hotspots of nutrient recycling. We measured nitrogen (N) and phosphorus (P) excretion rates of 47 species of fish in an N-limited Neotropical stream, and we combined these data with population densities in each of 49 stream channel units to estimate unit- and reach-scale nutrient recycling. Species varied widely in rates of N …

Terrapene Ornata (Ornate Box Turtle) Predation On Cliff Swallows, Mary Bomberger Brown, Charles R. Brown

School of Natural Resources: Faculty Publications

During a 25-year study of Cliff Swallows (Petrochelidon pyrrhonota) in southwestern Nebraska, we observed Terrapene ornata prey, or attempt to prey, on swallows. On one occasion as large numbers of birds flushed and hit the net, the weight of the birds pulled the net down to ground level. One T. ornata, which was seen regularly at the colony, approached one adult Cliff Swallow that was very low in the net and killed it by biting and eating its head. After killing the bird, the turtle walked away carrying the head.

Experimental Inoculation Of House Sparrows (Passer Domesticus) With Buggy Creek Virus, Kathryn P. Huyvaert, Amy T. Moore, Nicholas A. Panella, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

School of Natural Resources: Faculty Publications

We performed experimental inoculations of house sparrows (Passer domesticus) with Buggy Creek virus (BCRV), a poorly known alphavirus (Togaviridae) vectored primarily by the swallow bug (Hemiptera: Cimicidae: Oeciacus vicarius) that is an ectoparasite of the cliff swallow (Petrochelidon pyrrhonota) and house sparrow. Viremias were detected by plaque assay in two of six birds on days 1–3 postinoculation; viremia was highest on day 2. Viral RNA was detected by reverse transcriptase-polymerase chain reaction (RT-PCR) in blood of six of 12 birds ranging from day 1 to day 15 postinoculation. Infectious BCRV was detected in …
