No Effect Of Seed Source On Multiple Aspects Of Ecosystem Functioning During Ecological Restoration: Cultivars Compared To Local Ecotypes Of Dominant Grasses, Sara G. Baer, David J. Gibson, Danny J. Gustafson, Allison M. Benscoter, Lewis K. Reed, Ryan E. Campbell, Ryan P. Klopf, Jason E. Willand, Ben R. Wodika

Publications

Genetic principles underlie recommendations to use local seed, but a paucity of information exists on the genetic distinction and ecological consequences of using different seed sources in restorations. We established a field experiment to test whether cultivars and local ecotypes of dominant prairie grasses were genetically distinct and differentially influenced ecosystem functioning. Whole plots were assigned to cultivar and local ecotype grass sources. Three subplots within each whole plot were seeded to unique pools of subordinate species. The cultivar of the increasingly dominant grass, Sorghastrum nutans, was genetically different than the local ecotype, but genetic diversity was similar between the …

Late Archaic Inter-Personal Violence In The Middle Tennessee Valley, William Edwin Devore

Electronic Theses and Dissertations Archive

Three hundred and seventy sets of Late Archaic remains from Mulberry Creek, Perry, Flint River, Cox Mound, and Cox Village in the Middle Tennessee Valley are examined for trophy taking. The research was conducted to determine if trophy taking varies across the valley, who the victims are, what the frequencies of the types of trophies are, and how trophy taking manifest in the bioarchaeological record.Trophy taking varies across the valley, with higher levels in the west end of the valley. Trophy taking was seen in all age groups, and in both males and females. Sixty of these individuals had 94 …

Gene Expression Studies For The Analysis Of Domoic Acid Production In The Marine Diatom Pseudo-Nitzschia Multiseries, Katie R. Boissonneault, Brooks M. Henningsen, Stephen S. Bates, Deborah L. Robertson, Sean Milton, Jerry Pelletier, Deborah A. Hogan, David E. Housman

Biology

Background: Pseudo-nitzschia multiseries Hasle (Hasle) (Ps-n) is distinctive among the ecologically important marine diatoms because it produces the neurotoxin domoic acid. Although the biology of Ps-n has been investigated intensely, the characterization of the genes and biochemical pathways leading to domoic acid biosynthesis has been limited. To identify transcripts whose levels correlate with domoic acid production, we analyzed Ps-n under conditions of high and low domoic acid production by cDNA microarray technology and reverse-transcription quantitative PCR (RT-qPCR) methods. Our goals included identifying and validating robust reference genes for Ps-n RNA expression analysis under these conditions. Results: Through microarray analysis of …

Assessing The Performance Of A Northern Gulf Of Mexico Tidal Model Using Satellite Imagery, Stephen C. Medeiros, Scott C. Hagen, Naira Chaouch, Jesse Feyen, Marouane Temimi, John F. Weishampel, Yuji Funakoshi, Reza Khanbilvardi

Publications and Research

Tidal harmonic analysis simulations along with simulations spanning four specific historical time periods in 2003 and 2004 were conducted to test the performance of a northern Gulf of Mexico tidal model. A recently developed method for detecting inundated areas based on integrated remotely sensed data (i.e., Radarsat-1, aerial imagery, LiDAR, Landsat 7 ETM+) was applied to assess the performance of the tidal model. The analysis demonstrates the applicability of the method and its agreement with traditional performance assessment techniques such as harmonic resynthesis and water level time series analysis. Based on the flooded/non-flooded coastal areas estimated by the integrated remotely …

Raggio, Felicia Goldsmith, M'Famara Goita, Reshani N. Senevirathne, Ian L. Brown, Christine Pelkman, June Zhou, John Finley, Holiday A. Durham, Michael J. Keenan

Faculty Publications

Objective The effects of type 2 resistant starch from high-amylose maize (HAM-RS2) in rodents fed with low-fat diets were demonstrated in previous studies. Fish oil is also reported to reduce body fat. In the current study, the effects of high fat and fish oil on HAM-RS2 feeding in rats were investigated. Design and Methods Rats were fed 0 or 27% (weight) HAM-RS2 with low (15% energy) or high fat (42% energy) diets that included 0 or 10% (energy) tuna oil to test the effect of HAM-RS2 in diet-induced obesity and effects of tuna oil. Data were analyzed as 2 × …

Dietary Resistant Starch Improves Selected Brain And Behavioral Functions In Adult And Aged Rodents, June Zhou, Michael J. Keenan, Sun Ok Fernandez-Kim, Paul J. Pistell, Donald K. Ingram, Bing Li, Anne M. Raggio, Li Shen, Hanjie Zhang, Kathleen L. Mccutcheon, Richard T. Tulley, Marc R. Blackman, Jeffrey N. Keller, Roy J. Martin

Faculty Publications

Resistant starch (RS) is a dietary fiber that exerts multiple beneficial effects. The current study explored the effects of dietary RS on selected brain and behavioral functions in adult and aged rodents. Because glucokinase (GK) expression in hypothalamic arcuate nucleus and area postrema of the brainstem is important for brain glucose sensing, GK mRNA was measured by brain nuclei microdissection and PCR. Adult RS-fed rats had a higher GK mRNA than controls in both brain nuclei, an indicator of improved brain glucose sensing. Next, we tested whether dietary RS improve selected behaviors in aged mice. RS-fed aged mice exhibited (i) …

Comparing Types Of Student Placement And The Effect On Achievement For Students With Disabilities, Patricia Mason

Doctoral Dissertations and Projects

Since implementing No Child Left Behind, schools have improved student achievement while also preparing students for the 21st century. Schools continue to strive for 100% proficiency in all subgroups by 2014, but achievement gap exists for students with disabilities. This study used a causal comparative research design to test the concept of co-teaching by comparing types of placement for students with disabilities and the effect on student achievement. For this study, placement was considered where the student received instruction in either a general education class or a co-taught class during 9th through 11th grade. Student achievement was based on the …

Game Design As Authentic Science: Creating Low-Tech Games That Do Science, Jason Paul Siko, Michael Barbour

Education Faculty Publications

Many students love everything about video games, so teaching them to use technology to design their own games around content is an assignment that can offer built-in engagement. The problem, however, is that teachers often don’t have the time or expertise to teach computer programming, let alone content and process skills. On top of that, installing game design software can create friction between the teaching staff and technology department.

That’s where Microsoft PowerPoint comes in. Did you know you can help your students create—from scratch or from a template—a video game using PowerPoint?

On Comparison Of Exponential And Hyperbolic Exponential Growth Models In Height/Diameter Increment Of Pines (Pinus Caribaea), S. O. Oyamakin, A. U. Chukwu, T. A. Bamiduro

Journal of Modern Applied Statistical Methods

A new tree growth model called the hyperbolic exponential nonlinear growth model is suggested. Its ability in model prediction was compared with the Malthus or exponential growth model an approach which mimicked the natural variability of heights/diameter increment with respect to age and therefore provides more realistic height/diameter predictions as demonstrated by the results of the Kolmogorov Smirnov test and Shapiro-Wilk test. The mean function of top height/Dbh over age using the two models under study predicted closely the observed values of top height/Dbh in the Hyperbolic exponential nonlinear growth models better than the ordinary exponential growth model without violating …

Physiological Fluid Specific Agglomeration Patterns Diminish Gold Nanorod Photothermal Characteristics, Kristen K. Comfort, Jared W. Speltz, Bradley M. Stacy, Larry R. Dosser, Saber M. Hussain

Chemical and Materials Engineering Faculty Publications

Investigations into the use of gold nanorods (Au-NRs) for biological applications are growing exponentially due to their distinctive physicochemical properties, which make them advantageous over other nanomaterials. Au-NRs are particularly renowned for their plasmonic characteristics, which generate a robust photothermal response when stimulated with light at a wavelength matching their surface plasmon resonance. Numerous reports have explored this nanophotonic phenomenon for temperature driven therapies; however, to date there is a significant knowledge gap pertaining to the kinetic heating profile of Au-NRs within a controlled physiological setting. In the present study, the impact of environmental composition on Au-NR behavior and degree …

Filopodia As Sensors, Carol A. Heckman, H. K. Plummer

Biological Sciences Faculty Publications

Filopodia are sensors on both excitable and non-excitable cells. The sensing function is well documented in neurons and blood vessels of adult animals and is obvious during dorsal closure in embryonic development. Nerve cells extend neurites in a bidirectional fashion with growth cones at the tips where filopodia are concentrated. Their sensing of environmental cues underpins the axon's ability to "guide," bypassing non-target cells and moving toward the target to be innervated. This review focuses on the role of filopodia structure and dynamics in the detection of environmental cues, including both the extracellular matrix (ECM) and the surfaces of neighboring …

Lack Of Rbl1/P107 Effects On Cell Proliferation And Maturation In The Inner Ear, Sonia M. Rocha-Sanchez, Laura R. Scheetz, Sabrina Siddiqi, Michael W. Weston, Lynette M. Smith, Kate Dempsey, Hesham Ali, Joann Mcgee, Edward J. Walsh

Information Systems and Quantitative Analysis Faculty Publications

Loss of postnatal mammalian auditory hair cells (HCs) is irreversible. Earlier studies have highlighted the importance of the Retinoblastoma family of proteins (pRBs) (i.e., Rb1, Rbl1/p107, and Rbl2/p130) in the auditory cells’ proliferation and emphasized our lack of information on their specific roles in the auditory system. We have previously demonstrated that lack of Rbl2/p130 moderately affects HCs’ and supporting cells’ (SCs) proliferation. Here, we present evidence supporting multiple roles for Rbl1/p107 in the developing and mature mouse organ of Corti (OC). Like other pRBs, Rbl1/p107 is expressed in the OC, particularly in the Hensen’s and Deiters’ cells. Moreover, Rbl1/p107 …

Identification And Rna Binding Characterization Of Plant Virus Rna Silencing Suppressor Proteins, Jeff Vargason, Carissa J. Burch, Jesse W. Wilson

Faculty Publications - Department of Biological & Molecular Science

Suppression is a common mechanism employed by viruses to evade the antiviral effects of the host’s RNA silencing pathway. The activity of suppression has commonly been localized to gene products in the virus, but the variety of mechanisms used in suppression by these viral proteins spans nearly the complete biochemical pathway of RNA silencing in the host. This review describes the agrofiltration assay and a slightly modified version of the agro-infiltration assay called co-infiltration, which are common methods used to observe RNA silencing and identify viral silencing suppressor proteins in plants, respectively. In addition, this review will provide an overview …

Making Sense: Rhetoric, Perception, And Materiality, Aaron P. Donaldson

Electronic Theses and Dissertations

This dissertation dwells on the intersections of language-use and perception. The premise is that language makes literal sense and this reality has profound implications for those Burke called "symbol-using/mis-using animals." Communication scholars have long accepted a model of communication that positions language as "constitutive articulate contact" as opposed to a discrete means of transmission (Stewart, 1994), but a great deal of work remains to be done in terms of developing the implications for individuals and their language-use.

Chapter One explores the stances embraced by rhetorical materialists struggling to describe how language matters. The first chapter fields a series of critiques …

Decreased Pulmonary Function Measured In Children Exposed To High Environmental Relative Moldiness Index Homes, Stephen J. Vesper, Larry Wymer, Suzanne Kennedy, Linda Faye Grimsley

Faculty and Staff Publications

Background: Exposures to water-damaged homes/buildings has been linked to deficits in respiratory health. However, accurately quantifying this linkage has been difficult because of the methods used to assess water damage and respiratory health.

Purpose: The goal of this analysis was to determine the correlation between the water-damage, as defined by the Environmental Relative Moldiness Index (ERMI) value in an asthmatic child’s home, and the child’s pulmonary function measured by spirometry, “forced expiratory volume in one second, percent predicted” or FEV1%.

Methods: This analysis utilized data obtained from the “Heads-off Environmental Asthma in Louisiana” (HEAL) study. The children (n= 109), 6 …

Cytochrome P450 Family 1 Inhibitors And Structure-Activity Relationships, Jiawang Liu, Jayalakshmi Sridhar, Maryam Foroozesh

Faculty and Staff Publications

With the widespread use of O-alkoxyresorufin dealkylation assays since the 1990s, thousands of inhibitors of cytochrome P450 family 1 enzymes (P450s 1A1, 1A2, and 1B1) have been identified and studied. Generally, planar polycyclic molecules such as polycyclic aromatic hydrocarbons, stilbenoids, and flavonoids are considered to potentially be effective inhibitors of these enzymes, however, the details of the structure-activity relationships and selectivity of these inhibitors are still ambiguous. In this review, we thoroughly discuss the selectivity of many representative P450 family 1 inhibitors reported in the past 20 years through a meta-analysis.

Comparison Of Electrogustometrically Determined Taste Threshold And Phenylthiocarbamide Sensitivity Between Non-Diabetic Subjects With First Degree Relatives With Type 2 Diabetes And Non-Diabetic Subjects Without Type 2 Diabetic First Degree Relatives, Matthew E. Joseph Do

PCOM Biomedical Studies Student Scholarship

Diabetes is a systemic degenerative disease, having adverse effects on many different organ systems. Nerve conduction specifically related to taste is one of the affected functions and can lead to altered taste perceptions and taste thresholds. Electrogustometry was used in this study to evaluate taste thresholds, and taste sensitivity was tested using phenylthiocarbamide-impregnated testing strips. Healthy non-diabetic subjects were divided into two experimental groups: One with a first degree relative with Type 2 diabetes and the other matched controls having no family history of Type 2 diabetes. The hypotheses: 1). There is a significant difference in taste threshold values and …

The Drosophila T-Box Transcription Factor Midline Functions Within The Notch-Delta Signaling Pathway To Specify Sensory Organ Precursor Cell Fates And Regulates Cell Survival Within The Eye Imaginal Disc, Sudeshna Das, Q. Brent Chen, Joseph D. Saucier, Brandon Drescher, Yan Zong, Sarah E. Morgan, John Forstall, Andrew Meriwether, Randy Toranzo, Sandra M. Leal

Faculty Publications

We report that the T-box transcription factor Midline (Mid), an evolutionary conserved homolog of the vertebrate Tbx20 protein, functions within the Notch-Delta signaling pathway essential for specifying the fates of sensory organ precursor (SOP) cells. These findings complement an established history of research showing that Mid regulates the cell-fate specification of diverse cell types within the developing heart, epidermis and central nervous system. Tbx20 has been detected in unique neuronal and epithelial cells of embryonic eye tissues in both mice and humans. However, the mechanisms by which either Mid or Tbx20 function to regulate cell-fate specification or other critical aspects …
