Intravenous Polyethylene Glycol Inhibits The Loss Of Cerebral Cells After Brain Injury, Andrew O. Koob, Bradley S. Duerstock, Charles F. Babbs, Yinlong Sun, Richard B. Borgens

Weldon School of Biomedical Engineering Faculty Publications

We have tested the effectiveness of polyethylene glycol (PEG) to restore the integrity of neuronal membranes after mechanical damage secondary to severe traumatic brain injury (TBI) produced by a standardized head injury model in rats. We provide additional detail on the standardization of this model, particularly the use and storage of foam bedding that serves to both support the animal during the impact procedure and to dampen the acceleration of the brass weight. Further, we employed a dye exclusion technique using ethidium bromide (EB; quantitative evaluation) and horseradish peroxidase (HRP; qualitative evaluation). Both have been successfully used previously to evaluate …

Psychological And Psychophysiological Effects Of A High-Mountain Expedition To Tibet, Marcus Stück, Hans-Ullrich Balzer, Karl Hecht, Harry Schröder

Journal of Human Performance in Extreme Environments

In March 1999 a team of 8 mountaineers (6 men and 2 women) climbed up the 6th highest mountain of the world: The Cho Oyo (8201 m), located in the high mountains of Tibet. During the expedition, we investigated the effects of high mountaineering on various psychological variables (e.g., anxiety) and psychophysiological variables (e.g. blood pressure, pulse, skin-resistance) as well as the ability to relax at different points of time (2 premeasures before, three measures during, and one post-measure immediate after the Expedition). Due to a long-term monitoring of the skin resistance, we can summarize that three different adaptation levels …

Effect Of Viscoelasticity On Quality Factor Of Microcantilever Chemical Sensors: Optimal Coating Thickness For Minimum Limit Of Detection, F. Lochon, Isabelle Dufour, D. Rebière, U. Sampath, Stephen M. Heinrich, Fabien Josse

Civil and Environmental Engineering Faculty Research and Publications

Microcantilevers with polymer coatings hold great promise as resonant chemical sensors. It is known that the coated cantilever sensitivity increases with coating thickness; however, the drawback of increasing the coating thickness is the increase of the frequency noise and thus the deterioration of the sensor's limit of detection. In this paper, an analytical expression for the viscoelastic losses in the coating, hence the quality factor is established and is used to explain the observed increase of the frequency noise with the polymer thickness. This result is then used to demonstrate that an optimum coating thickness exists that minimise the limit …

Resistant Turfgrasses For Improved Chinch Bug Management, Tiffany Heng-Moss, Frederick P. Baxendale, Robert C. Shearman, Thomas E. Eickhoff

Department of Entomology: Faculty Publications

Researchers at the University of Nebraska evaluated selected cool- and warm-season turfgrasses for resistance to chinch bugs in the Blissus complex, and documented the presence of multiple chinch bug resistance in these turfgrasses.

Greenhouse and field screening studies were initiated to search for cool- and warm-season turfgrasses with resistance to chinch bugs in the Blissus complex. Several warmseason turfgrasses (buffalograss, zoysiagrass, and bermudagrass) with resistance to the western chinch bug have been identified.

Studies are currently underway to investigate the biochemical and physiological mechanisms underlying resistant turfgrasses. This information is fundamentally important for formulating plant breeding strategies, and subsequently developing …

Children’S Play In Cross-Cultural Perspective: A New Look At The Six Cultures Study , Carolyn P. Edwards

Department of Child, Youth, and Family Studies: Faculty Publications

A qualitative and quantitative reanalysis of the Six Cultures data on children’s play, collected in the 1950s, was performed to revisit worlds of childhood during a time when sample communities were more isolated from mass markets and media than they are today. A count was performed of children aged 3 to 10 in each community sample scored as engaging in creative-constructive play, fantasy play, role play, and games with rules. Children from Nyansongo and Khalapur scored lowest overall, those from Tarong and Juxtlahuaca scored intermediate, and those from Taira and Orchard Town scored highest. Cultural norms and opportunities determined how …

Does Choice Of Estimators Influence Conclusions From True Metabolizable Energy Feeding Trials?, Mark H. Sherfy, Roy L. Kirkpatrick, Kenneth E. Webb Jr.

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

True metabolizable energy (TME) is a measure of avian dietary quality that accounts for metabolic fecal and endogenous urinary energy losses (EL) of non-dietary origin. The TME is calculated using a bird fed the test diet and an estimate of EL derived from another bird (Paired Bird Correction), the same bird (Self Correction), or several other birds (Group Mean Correction). We evaluated precision of these estimators by using each to calculate TME of three seed diets in blue-winged teal (Anas discors). The TME varied by <2% among estimators for all three diets, and Self Correction produced the least variable TMEs for each. The TME did not differ between estimators in nine paired comparisons within diets, but variation between estimators within individual birds was sufficient to be of practical consequence. Although differences in precision among methods were slight, Self Correction required the lowest sample size to achieve a given precision. Feeding trial methods that minimize variation among individuals have several desirable properties, including higher precision of TME estimates and more rigorous experimental control. Consequently, we believe that Self Correction is most likely to accurately represent nutritional value of food items and should be considered the standard method for TME feeding trials.

Mountain Plover Population Responses To Black-Tailed Prairie Dogs In Montana, Stephen J. Dinsmore, Gary C. White, Fritz L. Knopf

United States Geological Survey: Staff Publications

We studied a local population of mountain plovers (Charadrius montanus) in southern Phillips County, Montana, USA, from 1995 to 2000 to estimate annual rates of recruitment rate (f) and population change (λ). We used Pradel models, and we modeled λ as a constant across years, as a linear time trend, as year-specific, and with an additive effect of area occupied by prairie dogs (Cynomys ludovicianus). We modeled recruitment rate (f) as a function of area occupied by prairie dogs with the remaining model structure identical to the best model used to estimate λ. Our results indicated …

A Multi-Forest Comparison Of Dietary Preferences And Seed Dispersal By Ateles Spp., Sabrina E. Russo, Christina J. Campbell, J. Lawrence Dew, Pablo R. Stevenson, Scott A. Suarez

School of Biological Sciences: Faculty Publications

Investigations of coevolutionary relationships between plants and the animals that disperse their seeds suggest that disperser-plant interactions are likely shaped by diffuse, rather than species-to-species, coevolution. We studied the role of dietary plasticity in shaping the potential for diffuse coevolution by comparing dietary fruit preferences and seed dispersal by 3 species of spider monkeys (Ateles spp.) in 4 moist forests in Colombia, Ecuador, Panama, and Surinam. In all forests, spider monkeys were highly frugivorous and preyed upon seeds of few species. We estimated dietary use of fruiting taxa based on absolute consumption and preference, which accounts for resource availability. …

The Symmetry Of Longevity, Lawrence G. Harshman, Hans-Georg Müller, Xueli Liu, Yue Wang, James R. Carey

Lawrence G. Harshman Publications

We tested the hypothesis that relatively symmetrical flies live longer. Vein measurements on the left and right wings from the same individual were used to characterize bilateral symmetry in relationship to age-specific survival in defined cohorts. A longitudinal cohort study supported the hypothesis of a correlation between bilateral symmetry and longevity. For another type of experiment, wings were removed from females and males at approximately the beginning of adult life. Thus, there would be no effect of wings per se on adult survival. These wings were measured to characterize bilateral asymmetry, and the day of death of each dewinged individual …

Saudi Medical Journal

OBJECTIVE: The elderly population continues to increase in most countries and inadequate nutrition is a common problem affecting their functional and physical status. Therefore, we should periodically assess the nutritional status of the elderly using practical methods. Our study objectives are to assess the nutritional status of the elderly using 2 different methods: Mini Nutritional Assessment (MNA) and Nutritional Screening Initiative Checklist (NSIC), and to evaluate the consistency of the methods. METHODS: We carried out a cross-sectional study between February 2003 and March 2004. We included a total of 1,564 elderly volunteers living in Ankara, Turkey, with median (± inter …

Genetic And Spatial Structure Within A Swift Fox Population, Ann M. Kitchen, Eric M. Gese, Lisette P. Waits, Seija M. Karki, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

1. We incorporated spatial data on swift foxes (Vulpes velox) with genetic analysis to assess the influence of relatedness between individuals on their social and spatial ecology. We recorded the space use patterns of 188 radio-collared swift foxes in southeastern Colorado from January 1997 to December 2000. One hundred and sixty-seven foxes were also genotyped at 11 microsatellite DNA loci and the degree of relatedness between individuals was estimated.

2. We described the genetic structure of the population by examining the relatedness of neighbors and the relationship between the spatial and genetic distance of all individuals. We found …

Will Travel For Food: Spatial Discounting In Two New World Monkeys, Jeffrey R. Stevens, Alexandra G. Rosati, Kathryn R. Ross, Marc D. Hauser

Department of Psychology: Faculty Publications

Nonhuman animals steeply discount the future, showing a preference for small, immediate over large, delayed rewards [1–5]. Currently unclear is whether discounting functions depend on context. Here, we examine the effects of spatial context on discounting in cotton-top tamarins (Saguinus oedipus) and common marmosets (Callithrix jacchus), species known to differ in temporal discounting [5]. We presented subjects with a choice between small, nearby rewards and large, distant rewards. Tamarins traveled farther for the large reward than marmosets, attending to the ratio of reward differences rather than their absolute values. This species difference contrasts with performance on …

Three Rarely Reported Digeneans Inhabiting Amphibians From Vancouver Island, British Columbia, Canada, David Zamparo, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three rarely reported species of digeneans were collected in amphibian hosts from Diversion Reservoir, Sooke, Vancouver Island, British Columbia, Canada, The endangered anuran Rana aurora hosted Glypthelmins californiensis, Gorgoderina multilobata, and Megalodiscus microphagus. In addition, the anuran Pseudacris regilia and the caudatan Taricha granulosa hosted Megalodiscus microphagus. Gorgoderina multilobata has been reported only once since 1936 and has never been reported outside of California. We note several characters not previously reported for Gorgoderina multilobata and G. aurora.

Beaver (Castor Canadensis) Impacts On Herbaceous And Woody Vegetation In Southeastern Georgia, Jessica R. Brzyski

College of Graduate Studies: Theses & Dissertations

North American beavers are considered ecosystem engineers. Their activities can quickly and drastically alter habitat properties and perhaps permit highly aggressive colonizing plants, notably non-native species, to invade and potentially dominate. This study examined if beavers in southeastern Georgia have an effect on the terrestrial plant community. Sampling areas included beaver modified (N=9) and nearby but relatively non-impacted riparian habitat (N=9) in a matched pairs design. Vegetation surveys were performed in spring and summer. Species richness was calculated for herbs, vines, woody seedlings, and woody vegetation. Richness of herbaceous vegetation was higher at distances closer to shore while richness of …

A Phylogenetic Analysis Of Vanzolinius Heyer, 1974 (Amphibia, Anura, Leptodactylidae): Taxonomic And Life History Implications, Rafael O. De Sá, W. Ronald Heyer, Arley Camargo

Biology Faculty Publications

The validity of the monotypic leptodactylid frog genus Vanzolinius Heyer, 1974 has been questioned recently. We explore the relationship of Vanzolinius discodactylus within the cluster of closely related genera Adenomera, Leptodacylus, and Lithodytes with both morphological and molecular data sets. Morphological and combined morphological and molecular data were analyzed using maximum parsimony; molecular data sets were analyzed with maximum likelihood methods. The resultant relationships are unambiguous in Vanzolinius being imbedded within Leptodactylus. In order to maintain Leptodactylus as a monophyletic genus, Vanzolinius is placed in the synonymy of Leptodactylus Fitzinger, 1826. The implications of relationships analyzed in …
