Quality Vs Quantity: The Effect Of Aristolochic Acids On Preference And Performance Of A Non-Specialist Herbivore, Samantha Eileen Jeude

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

As immobile organisms, plants have evolved many strategies for defense against herbivores. These defenses can be physical, such as thorns, or chemical, such as antifeedant compounds. Most plants possess chemical compounds that serve a deterrent function against at least some herbivores. Aristolochic acids are alkaloids characteristic of plants of the genus Aristolochia. Although their toxicity and efficacy as herbivore deterrents have been documented, it is unknown whether different kinds of these compounds elicit different responses in herbivores. In this study, we use the generalist caterpillar Spodoptera exigua as a bioassay to evaluate both qualitative and quantitative effects of four aristolochic …

Variation In The Abundance Of Bees Across Distinct Montane Meadows, Jessica N. Welch

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Across different landscapes, plant abundance and richness change. Bee distributions may vary spatially or temporally in accordance with differences in floral diversity. I used a habitat-based approach to investigate the hypothesis that the abundance of bees in assemblages varied among three distinct meadow types: dry meadow, wet meadow-Veratrum, and wet meadow-Salix. Patterns of bee abundance were sampled using bee bowls and netting around Gothic, Colorado. I sampled four triplets of sites (each consisting of the three meadow types) every other week, between June 22 and August 26, 2009. In total, I caught 2,938 bees and identified each of them to …

Arabidopsis Thaliana Myosin Xi Is Necessary For Cell Fate Determination In Root Epidermis, Kevin Kuo

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Root hairs are specialized epidermal cells with important functions, such as absorbing water and nutrients from soil. In Arabidopsis thaliana, root hairs develop in a strict position-dependent mechanism that results in alternating longitudinal hair and non-hair cell files along the surface of the root. This invariant pattern is determined, in large part, by a complex network of transcription factors in the epidermis. However, epidermal cells are also highly plastic and have the ability to promote root hair growth even after the hairless cell fate has been determined by transcriptional control. Recently, it has been observed that the mutants of a …

In Vitro Amplification Of Misfolded Prion Protein Using Lysate Of Cultured Cells, Charles E. Mays, Jihyun Yeom, Hae-Eun Kang, Jifeng Bian, Vadim Khaychuk, Younghwan Kim, Jason C Bartz, Glenn C Telling, Chongsuk Ryou

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Protein misfolding cyclic amplification (PMCA) recapitulates the prion protein (PrP) conversion process under cell-free conditions. PMCA was initially established with brain material and then with further simplified constituents such as partially purified and recombinant PrP. However, availability of brain material from some species or brain material from animals with certain mutations or polymorphisms within the PrP gene is often limited. Moreover, preparation of native PrP from mammalian cells and tissues, as well as recombinant PrP from bacterial cells, involves time-consuming purification steps. To establish a convenient and versatile PMCA procedure unrestricted to the availability of substrate sources, we attempted to …

Increase Serum Il-8 Level In Iraqi Patients With Helicobacter Pylori Caga Genotype Infection, Sanaa Khudhur, Jasim Karhoot, Jassim Al-Khafaji, Jasim Mohsin

Iraqi Postgraduate Medical Journal

ABSTRACT: BACKGROUND: More than half of all humans are colonized in their stomachs by Helicobacter pylori . That carriage was nearly universal among adults in developing countries suggests that in earlier times most humans carried these organisms.H. pylori was an important human pathogen that causes gastritis and is strongly associated with gastric ulcers, gastric adenocarcinomas, and mucosa-associated lymphoid tissue lymphomas. In response to H. pylori, interleukin-8 (IL-8) was secreted from host cells to attract components of the innate and adaptive immune systems to the site of infection.CagA+ cells induce higher levels of the proinflammatory IL-8 cytokine. That such effects are …

Evolution Of A Major Drug Metabolizing Enzyme Defect In The Domestic Cat And Other Felidae: Phylogenetic Timing And The Role Of Hypercarnivory, Binu Shrestha, J. Michael Reed, Philip T. Starks, Gretchen E. Kaufman, Jared V. Goldstone, Melody E. Roelke, Stephen J. O'Brien, Klaus-Peter Koepfli, Laurence Frank, Michael H. Court

Biology Faculty Articles

The domestic cat (Felis catus) shows remarkable sensitivity to the adverse effects of phenolic drugs, including acetaminophen and aspirin, as well as structurally-related toxicants found in the diet and environment. This idiosyncrasy results from pseudogenization of the gene encoding UDP-glucuronosyltransferase (UGT) 1A6, the major species-conserved phenol detoxification enzyme. Here, we established the phylogenetic timing of disruptive UGT1A6 mutations and explored the hypothesis that gene inactivation in cats was enabled by minimal exposure to plant-derived toxicants. Fixation of the UGT1A6 pseudogene was estimated to have occurred between 35 and 11 million years ago with all extant Felidae having dysfunctional …

Information-Seeking Behaviors Of First-Semester Veterinary Students: A Preliminary Report, Sharon A. Weiner, Gretchen Stephens, Abdelfattah Y.M. Nour

Libraries Faculty and Staff Scholarship and Research

Although emphasis in veterinary education is increasingly being placed on the ability to find, use, and communicate information, studies on the information behaviors of veterinary students or professionals are few. Improved knowledge in this area will provide valuable information for course and curriculum planning and the design of information resources. This article describes a survey of the information-seeking behaviors of first-semester veterinary students at Purdue University. A survey was administered as the first phase of a progressive semester-long assignment for a first semester DVM course in systemic mammalian physiology. The survey probed for understanding of the scientific literature and its …

Characterization And Genetic Analysis Of The Cellulolytic Microorganism Thermobifida Fusca, Yu Deng

Theses and Dissertations

Currently, one of the hurdles hindering efficient production of cellulosic biofuel is the recalcitrant nature of cellulose to hydrolysis. A wide variety of cellulase enzymes are found natively in microorganisms that can potentially be used to effectively hydrolyze cellulose to fermentable sugars. Thermobifida fusca is a high G-C content, thermophilic, gram-positive soil actinobacterium with high cellulolytic activity. The phenomenological and mechanistic parameters affecting cellulase activity were studied in T. fusca and two mechanisms have been found: 1) transcriptions of cellulase-related genes were not closely associated with measured differences in cellulase activity and 2) cellular energetics (intracellular ATP) correlated more closely …

Protection Against Divergent Influenza H1n1 Virus By A Centralized Influenza Hemagglutinin, Eric A. Weaver, Adam M. Rubrum, Richard J. Webby, Michael A. Barry

School of Biological Sciences: Faculty Publications

Influenza poses a persistent worldwide threat to the human population. As evidenced by the 2009 H1N1 pandemic, current vaccine technologies are unable to respond rapidly to this constantly diverging pathogen. We tested the utility of adenovirus (Ad) vaccines expressing centralized consensus influenza antigens. Ad vaccines were produced within 2 months and protected against influenza in mice within 3 days of vaccination. Ad vaccines were able to protect at doses as low as 107 virus particles/kg indicating that approximately 1,000 human doses could be rapidly generated from standard Ad preparations. To generate broadly cross-reactive immune responses, centralized consensus antigens were constructed …

Life Cycle Assessment Of Greenhouse Gas Emissions From Ethanol And Biopolymers, Adam J. Liska, Xiao Xue Fang

Adam Liska Papers

Conclusions

• Regulatory LCA is not likely to be used for non‐fuel chemicals alone in the near future

• Significant GHG emission credits for corn‐ethanol can be obtained by using only roughly 6‐9% of initial starch for production of biopolymers based on previous LCA theory

• Pay close attention to values in calculating credits per kg—these have to stand up in litigation to ensure the credit

• Credits are proportional to the mass of polymer produced

• Many theoretical issues are uncertain and credits will only be determined in conjunction with EPA

• Indirect emissions are uncertain and are a …

Dynamics Of An Emerging Infectious Disease Of Amphibians: From Individuals To Communities, Matthew Damien Venesky

Electronic Theses and Dissertations Archive

Chytridiomycosis is an infectious disease of amphibians caused by the fungus Batrachochytrium dendrobatidis (Bd), and it has played an important role in the worldwide decline of amphibians. My dissertation research examined the consequences of Bdinfections on tadpole feeding biomechanics and activity, pathogen transmission, and host immunology. The keratinized labial teeth of Bd-infected Fowler's Toad (Anaxyrus [=Bufo] fowleri) and Grey Treefrog (Hyla versicolor) tadpoles slipped off of surfaces on which they grazed and were in contact with an algal-covered surface for a shorter duration of time during each feeding cycle. During feeding trials, Bd-infected A. fowleri and H. versicolor tadpoles obtained …

Variation Of Glucose Concentration During Different Phases Of Menstrual Cycle, Maysaa Jalal Majeed

Iraqi Postgraduate Medical Journal

ABSTRACT: BACKGROUND: A woman's menstrual cycle (and accompanying hormonal changes) can cause variations in blood glucose levels. Many women may note an increase in their blood glucose after ovulation, which then decreases once menstruation starts. These changes are caused by the hormones estrogen and progesterone, which occur at higher levels before period. They influence insulin in causing blood glucose to rise. It is important to test blood glucose levels during this cycle to be certain that blood sugar variations are attributed to menstruation. OBJECTIVE: To study the effect of sex hormones (testosterone, estradiol and progesterone) on the level of glucose; …

Age-Gaps In Sexual Partnerships: Seeing Beyond ‘Sugar Daddies’, Miles Q. Ott, Till Bärnighausen, Frank Tanser, Mark N. Lurie, Marie-Louise Newell

Statistical and Data Sciences: Faculty Publications

We examine for the first time age-mixing in sexual relationships in a population with very high HIV incidence and prevalence in rural South Africa. The highest levels of age assortativity (the pairing of like with like) were casual partnerships reported by men, the lowest levels were spousal relationships reported by women. Given the age–sex distribution of HIV prevalence in this population, interventions to decrease age-gaps in spousal relationships may be effective in reducing HIV incidence.

Department of Agronomy and Horticulture: Faculty Publications

Knowledge of genetic diversity, population structure, and degree of linkage disequilibrium (LD) in target association mapping populations is of great importance and is a prerequisite for LD-based mapping. In the present study, 96 genotypes comprising 92 accessions of the US peanut minicore collection, a component line of the tetraploid variety Florunner, diploid progenitors A. duranensis (AA) and A. ipaënsis (BB), and synthetic amphidiploid accession TxAG-6 were investigated with 392 simple sequence repeat (SSR) marker bands amplified using 32 highly-polymorphic SSR primer pairs. Both distance- and model-based (Bayesian) cluster analysis revealed the presence of structured diversity. In general, the wild-species accessions …

Can Parents Create Alcoholics?, Scott Lang, Paul Boellner

Counselor Education and Counseling Psychology Research Exchange Conference

Background: Research has shown a definitive genetic component to alcoholism, with children of alcoholic parents being much more likely to become alcoholics themselves when compared to children of non-alcoholics. Just because alcoholism runs in an individual's family does not guarantee that said individual will become an alcoholic. This paper tries to discern if the way a parent raises their child can have an effect on the likelihood of the child being an alcoholic later in life.

Results: A review of the literature suggests that there may be a correlation between a how a child is raised and the likelihood of …

Research Exchange. Reactive Attachment Disorder: Developing A Developmental Perspective, Johnathan M. Sumpter

Counselor Education and Counseling Psychology Research Exchange Conference

Reactive Attachment Disorder is a relatively young disorder. Researchers are just beginning to hash out the implications of this disorder on current children and future generations. However, there is much needed from criteria setting and researching leadership to mediate the process of gaining ground in assessing and treating this disorder. This meta-­‐analysis will provide an overview that will point out the diagnostic ambiguities, theoretical conflicts, and disjointed research of the previous decade’s work on RAD.
