Ige Enhances B Cell-Derived Exosomal Induced T Cell Proliferation, Brooks Keith

Theses and Dissertations

For many years it has been known that the injection of antigen bound to an antibody leads to more than a 1000-fold increase in antigen specific antibody response. This observation holds true for IgE, which is dependent upon CD23 expression, as this enhancement is not present in mice deficient in CD23. It also has been shown that when mice are injected with IgE-antigen complexes also display an increase in antigen specific T cell proliferation. While there are published studies that demonstrate a role for B cell derived exosomes in the activation and proliferation of T cells, none have focused upon …

Design And Development Of A Novel Transcranial Doppler Headset For Assessment Of Cerebral Blood Flow, Brian P. Watt

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Examining physiologic responses of cerebral blood flow (CBF) for subjects in challenging situations requires development of new technology. Challenging circumstances include strenuous physical activity, intensive care, and surgical procedures involving the head, neck and thorax. Headset technology to employ transcranial Doppler (TCD), which is commercially available, fails to meet several requirements for monitoring in these situations. These requirements include stable signal acquisition, non-interference with other physiological monitors, ability to fit all head sizes including infants and children. The design and development of a novel TCD headset was performed to meet these requirements. The new device theoretically allows the user to …

Effects Of Length Limits On Sexually Size Dimorphic Fishes, Peter J. Spirk

School of Natural Resources: Dissertations, Theses, and Student Research

Length limits are used by fishery managers as a method to alter size structure of fish populations. Unfortunately, biological differences between fish sexes (i.e., sexual-size dimorphism) may lead to sex-specific rates of recruitment, growth, and mortality. The addition of angler harvest to most aquatic systems likely accentuates differences in sex-specific rates by selectively harvesting the fastest-growing and largest fish from a population. The first objective of this study was to document the extent of sexual-size dimorphism for white bass and walleye at a Nebraska reservoir. Growth rates were similar between male and female white bass although male white bass were …

The Effects Of River Sediment, Endosulfan, And Moderate Hypoxia On Blue Crabs (Callinectes Sapidus) From The Tidal, Freshwater James River, Laura Williams

Theses and Dissertations

Juvenile male blue crabs move into the tidal, freshwater James River during warmer months to feed and grow by undergoing molting. In crustaceans, growth and molting are hormonally controlled. The physiological effects of a multiple-stressor environment are determined by comparing the blue crab’s oxygen uptake after exposure to pure sand, James River sediment, or endosulfan-spiked sand. The effect of multiple stressors on molting is measured by the activity level of N-acetyl-ß-glucosaminidase (NAG), an enzyme in epidermal tissue important to molting. The oxygen uptake was decreased by exposure to James River sediment but not for exposure to endosulfan for seven days. …

Septin Phosphorylation And Coiled-Coil Domains Function In Cell And Septin Ring Morphology In The Filamentous Fungus Ashbya Gossypii, Rebecca A. Meseroll, Patricia Occhipinti, Amy S. Gladfelter

Dartmouth Scholarship

Septins are a class of GTP-binding proteins conserved throughout many eukaryotes. Individual septin subunits associate with one another and assemble into heteromeric complexes that form filaments and higher-order structures in vivo. The mechanisms underlying the assembly and maintenance of higher-order structures in cells remain poorly understood. Septins in several organisms have been shown to be phosphorylated, although precisely how septin phosphorylation may be contributing to the formation of high-order septin structures is unknown. Four of the five septins expressed in the filamentous fungus, Ashbya gossypii, are phosphorylated, and we demonstrate here the diverse roles of these phosphorylation sites …

Perceived Stress And Surgical Wound Cytokine Patterns, Valentina Lucas

Theses and Dissertations

Normal wound healing is a complex process that occurs in overlapping phases and depends upon interactions of the patient, environment and a large number of cells, growth factors, cytokines, chemokines, and other biochemical mediators. Psychological stress has been shown to adversely affect the normal wound healing process through its impact on cellular immunity. Cellular immunity impacts wound healing through the production and regulation of many of the above biochemical mediators of wound healing. The purpose of this pilot study was to examine the relationships among pre- and post-operative psychological stress experienced by women who were undergoing either immediate or delayed …

Transgressing Sexuality: An Interdisciplinary Study Of Economic History, Anthropology, And Queer Theory, Jason Gary Damron

Dissertations and Theses

This interdisciplinary thesis examines the concept of sexuality through lenses provided by economic history, anthropology, and queer theory. A close reading reveals historical parallels from the late 1800s between concepts of a desiring, utility-maximizing economic subject on the one hand, and a desiring, carnally decisive sexological subject on the other. Social constructionists have persuasively argued that social and economic elites deploy the discourse of sexuality as a technique of discipline and social control in class- and gender-based struggles. Although prior scholarship discusses how contemporary ideas of sexuality reflect this origin, many anthropologists and queer theorists continue to use "sexuality" uncritically …

Exclusion And Xenophobia: Norwegian Society's Influences On Anders Behring Breivik's Counter-Jihadism, Anna Katariina Oraviita Eriksen

Master's Theses

On July 22^nd 2011 Norway was shocked by the first terrorist attacks on Norwegian soil since the German occupation during World War II. As Norway is internationally renowned as a peaceful and idyllic society the terrorist attacks, questions of why the attacks took place in Norway arose. My thesis examines which societal factors in Norway have contributed to Anders Behring Breivik's terrorist attacks in Oslo and on Utøya, July 22^nd 2011. To do so, I have employed qualitative content analysis of newspaper articles which has allowed me to extract themes relevant to determine which factors in the Norwegian …

Characterization Of Head Transcriptome And Analysis Of Gene Expression Involved In Caste Differentiation And Aggression In Odontotermes Formosanus (Shiraki), Qiuying Huang, Pengdong Sun, Xuguo Zhou, Chaoliang Lei

Entomology Faculty Publications

Background

The subterranean termite Odontotermes formosanus (Shiraki) is a serious insect pest of trees and dams in China. To date, very little is known about genomic or transcriptomic data for caste differentiation and aggression in O. formosanus. Hence, studies on transcriptome and gene expression profiling are helpful to better understand molecular basis underlying caste differentiation and aggressive behavior in O. formosanus.

Methodology and Principal Findings

Using the Illumina sequencing, we obtained more than 57 million sequencing reads derived from the heads of O. formosanus. These reads were assembled into 116,885 unique sequences (mean size = 536 bp). …

Projected Climate Change Impacts On The Hydrology And Temperature Of Pacific Northwest Rivers, Huan Wu, John S. Kimball, Marketa M. Elsner, Nate Mantua, Robert F. Adler, Jack Arthur Stanford

Biological Sciences Faculty Publications

A dominant river-tracing-based streamflow and temperature (DRTT) model was developed by coupling stream thermal dynamics with a source-sink routing model. The DRTT model was applied using 1/16 degree (similar to 6 km) resolution gridded daily surface meteorology inputs over a similar to 988,000 km(2) Pacific Northwest (PNW) domain to produce regional daily streamflow and temperature simulations from 1996 to 2005. The DRTT results showed favorable performance for simulation of daily stream temperature (mean R-2 = 0.72 and root-mean-square error = 2.35 degrees C) and discharge (mean R-2 = 0.52 and annual relative error 14%) against observations from 12 PNW streams. …

Comparison Of The Coleoptera Communities In Leaf Litter And Rotten Wood In Great Smoky Mountains National Park, Usa, Michael L. Ferro, Matthew L. Gimmel, Kyle E. Harms, Christopher E. Carlton

Insecta Mundi

The community within extremely decayed downed coarse woody debris, here referred to as decay class V (CWD5), has never been systematically sampled. The presumption has been that rotten wood is eventually overrun by surrounding soil and litter inhabitants. Leaf litter and CWD5 were sampled for Coleoptera with a sifting/ Berlese technique at three primary and three secondary forest sites in Great Smoky Mountains National Park, Tennessee, USA, during fall 2006 and spring 2007. A total of 4261 adult beetle specimens, representing 216 lowest identifiable taxa within 159 genera and 28 families, were collected. Sixty-six species (31%) were represented by single …

Natural History Of Four Species Of Platydracus Thomson (Coleoptera: Staphylinidae) In Heliconia Bourgaeana Petersen (Zingiberales: Heliconiaceae) Flower Bracts, J. H. Frank, M. A. Morón

Insecta Mundi

Abstract. The insect fauna within inflorescences of Heliconia bourgaeana Petersen (Zingiberales: Heliconiaceae) was evaluated in Parque Metlac, Fortín de las Flores, Veracruz, Mexico between May and October 1995. Floral bracts were present in May and some persisted to October, despite much destruction in August by a grackle, Quiscalus mexicanus (JF Gmelin) (Icteridae). Flowers were abundant in the bracts in May-June, after which their number declined as fruits matured. Insects that fed on the flowers were most abundant in May-June; several of them could be pollinators; the immature stages of most of these insects were absent from Heliconia Linnaeus. The floral …

Marie Von Ebner-Eschenbach's Ohne Liebe: A Translation And Commentary, Steven L. Peris

Theses and Dissertations

This thesis explores a short drama of Marie von Ebner-Eschenbach, Without Love. It provides not only a complete English translation of the work, but also an interpretative introduction. By first examining the life of Ebner-Eschenbach, I am able to provide insight to the origins of the play. Because Ebner-Eschenbach faced so much opposition in her drama writing career this one act play becomes more relevant. It contains similar themes to her other works such as: gender roles, the role of the aristocracy, and love in marriage. Without Love examines the role of love in marriage by providing the reader …

Leaf And Root Responses Of Three Wetland Tree Species To Anthropogenic-Generated Stressors, Donald Reon Baud

Electronic Theses and Dissertations Archive

Baud, Donald Reon. PhD. University of Memphis. December 2012. Leaf and Root Responses of Three Wetland Tree Species to Anthropogenic-generated Stressors. Major Professor: S. Reza Pezeshki.Published research to date has shown that anthropogenic-generated stressors, such as increased ultraviolet-B exposure, higher temperatures and the concomitant increase in herbivorous insect populations, as well as increased copper and ethanol contamination, are having a negative impact on plant growth and survival. However, there is a lack of data on the morphological and physiological responses woody wetland species. This series of independent, but related, experiments will focus on Salix nigra, Acer negundo, and Quercus phellos, …

Factors Affecting Infectivity And Pathogenicity Of Batrachochytrium Dendrobatidis In Amphibians., Forrest Michael Brem

Electronic Theses and Dissertations Archive

Wildlife diseases are a current threat to biodiversity, and amphibians have suffered the greatest disease-induced declines and extinctions in history. Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has contributed to recent pandemic population declines and extinctions of amphibians. My dissertation focused on factors that affect infectivity and pathogenicity of Bd in amphibian hosts. I demonstrated variation in critical aspects of Bd biology between Bd isolates from different climates, Panama and the USA. Panamanian Bd had larger thalli, higher overall zoospore production, and longer duration of zoospore production than Bd from the USA. I also demonstrated time-dependent rates of …

Genetic And Demographic Patterns Of The Raccoon (Procyon Lotor) Across Extended Spatio-Temporal Scales, John R. Hisey

Electronic Theses and Dissertations Archive

Population features and genetic structure of raccoons (Procyon lotor) and many other solitary-mammalian species are relatively unknown. To better understand these characteristics in P. lotor, microsatellite data collected at local, area, and transcontinental scales and 14 years of local mark-recapture data were used to assess the temporal and spatial extent of philopatry, dispersal, formation of lineages, and genetic patterns associated with these factors. Specifically, I tested the following predictions for raccoons: (1) long-term residency is common; (2) patterns of genetic variation are associated with isolation by distance; (3) closely related animals remain spatially clustered. Only 26 of 215 P. lotor …

Using Computer Assisted Tomography To Acquire More Detailed Subject Specific Information For Kinematic Analysis, Devin J. Conner

Electronic Theses and Dissertations Archive

Experimental knee simulators have been used to study knee kinematics of total knee replacements (TKR) in cadaver knees. Kinematic results are often reported using a Joint Coordinate System (JCS) introduced by Grood & Suntay in 1983. The JCS relies on bone landmarks in the knee which are removed when a TKR is performed. While it may be expedient to use the closest equivalents of the landmarks from the TKR to build the JCS (rather than the actual anatomic landmarks) doing so may introduce errors that could lead to misinterpretation of the kinematic results. Cadaver studies were performed on two posterior …
