Chemosensitivity In Mealworms And Darkling Beetles (Tenebrio Molitor) Across Oxygen And Carbon Dioxide Gradients, Andrew King Patterson

Browse all Theses and Dissertations

Breathing in most insects is controlled through a negative feedback loop consisting of signals (O₂, CO₂, pH), sensors (chemoreceptors), integrators (neural ganglia), and effectors (spiracles over tracheae). I hypothesized that mealworms and their adult counterparts Darkling beetles, Tenebrio molitor, can sense anoxic and hyperoxic environments and preferentially avoid these environments. I also hypothesize that mealworms are attracted to hypercarbia while Darkling beetles avoid hypercarbia. I constructed a test arena to create an O₂ or CO₂ gradient. Velocity, total distance traveled, and time spent in each area of the O₂ or CO₂ gradients …

Data Management And Data Facilitation In Multi-Center Large Cohort Health Care Studies, Wei Wang

Dissertations, Master's Theses and Master's Reports

Data management and data facilitation is the foundation and a critical part for scientific investigations, especially with large cohort studies on health care, which may have multiple components collected from different institutes or different areas due to efficiency, cost, enrollment considerations. In this thesis, I consider how to design and to implement data management with multi-center health care research data. The research project that I joined focuses mainly on environmental health science, and the primary goal is to investigate the impact of nutritional and toxicant exposures in environment during fetal and early postnatal life on individual’s health outcomes over the …

Benthic Marine Calcifiers Coexist With Caco3-Undersaturated Seawater Worldwide, Mario Lebrato, Andreas J. Andersson, Justin Baker Ries, Richard B. Aronson, Miles D. Lamare, Wolfgang Koeve, Andreas Oschlies, Maria Débora Iglesias-Rodríguez, Sven Thatje, M. Amsler, Stephanie C. Vos, D. O. B. Jones, H. A. Ruhl, A. R. Gates, J. B. Mcclintock

Ocean Engineering and Marine Sciences Faculty Publications

Ocean acidification and decreasing seawater saturation state with respect to calcium carbonate (CaCO3) minerals have raised concerns about the consequences to marine organisms that build CaCO3 structures. A large proportion of benthic marine calcifiers incorporate Mg2+ into their skeletons (Mg-calcite), which, in general, reduces mineral stability. The relative vulnerability of some marine calcifiers to ocean acidification appears linked to the relative solubility of their shell or skeletal mineralogy, although some organisms have sophisticated mechanisms for constructing and maintaining their CaCO3 structures causing deviation from this dependence. Nevertheless, few studies consider seawater saturation state with respect to the actual Mg-calcite mineralogy …

Applying Life Insurance Principles To Coastal Property Insurance To Incentivize Adaptation To Climate Change, Edward P. Richards

Journal Articles

Current levels of greenhouse gases will result in significant sea level rise in the future, irrespective of the success of any future mitigation efforts. Paleoclimate and geologic data from past periods of rising sea level show that low lying areas, especially river deltas which are home to half a billion people, will be inundated. The best way to represent this risk through insurance is to apply the human-life insurance model to coastal property insurance. Human-life insurance is based on the assumption that every insured will die. Because the risk of death increases with age, the cost of insurance increases with …

The Case For Health Literacy Research In Qatar: Identifying Avenues For Progress, Yasar Alani

Theses

Abstract This thesis studies the attitudes of healthcare provider and consumer groups in Qatar towards health literacy via health promotion. Using Q methodology, data from healthcare providers and consumers was analysed to determine relative attitudes towards previous and future health campaign strategies in Qatar. Consumer data was also collected to determine attitudes towards current health promotion campaigns and the perceived effectiveness of campaigns in encouraging behaviour change. The research also investigates the obstacles that prevent healthcare consumers from adopting the healthier lifestyle choices advocated by some of these campaigns. Participants were residents of Qatar.

The concept of health literacy was …

The Trans-Pacific Partnership:The Death-Knell Of Generic Pharmaceuticals?, Alexander Stimac

Vanderbilt Journal of Transnational Law

As global commerce continues to expand, many states find international trade agreements to be a useful tool to facilitate this continued expansion. Trade agreements permit developing or poorer nations to establish robust, mutually beneficial trade relationships with powerful economies such as the United States. In the face of regional competition from China, several nations bordering the Pacific Ocean, including the United States, have reached a far-reaching trade agreement called the Trans-Pacific Partnership (TPP). This Note will focus on one particular piece of the TPP: the pharmaceutical trade and the international availability of generic medicines. The TPP has the potential to …

Mystery Date: Advocating For A Harmonized System Of Expiration Date Labeling Of Food, Akshat Tiwari

Vanderbilt Journal of Transnational Law

Americans throw out roughly 25 percent of the food they bring home. Negative perceptions associated with expiration dates are a leading cause for this waste. However, a complex patchwork of state-run regulatory regimes and varying terminology makes it difficult for consumers to determine whether a food product is unsafe to eat or simply past a peak quality level arbitrarily set by manufacturers. Regulatory trends in Europe, the United Kingdom, Canada, Australia, and New Zealand suggest a move towards binding expiration date labeling through guidelines for establishing a "best before" or "use-by" date. This Note examines laws currently in place in …

Imaging & Diagnostic Radiology, East Africa

Mammographic density (MD) is a quantitative trait, measurable in all women, and is among the strongest markers of breast cancer risk. The population-based epidemiology of MD has revealed genetic, lifestyle and societal/environmental determinants, but studies have largely been conducted in women with similar westernized lifestyles living in countries with high breast cancer incidence rates. To benefit from the heterogeneity in risk factors and their combinations worldwide, we created an International Consortium on Mammographic Density (ICMD) to pool individual-level epidemiological and MD data from general population studies worldwide. ICMD aims to characterize determinants of MD more precisely, and to evaluate whether …

Two-Stage Psa System For Co2 Removal And Concentration During Closed-Loop Human Space Exploration Missions, Hanife Erden

Theses and Dissertations

A novel two-stage pressure swing adsorption (PSA) system has been developed to remove metabolic CO2 removal from the spacecraft cabin air of the International Space Station (ISS). This PSA system enriches and recovers the CO2 to make it suitable for use in a Sabatier reactor (CO2 reduction). This two-stage PSA process utilizes Stage 1 to concentrate metabolic CO2 from about 0.2667 vol% to about 40 to 60 vol% and Stage 2 to further enrich the CO2 product from Stage 1 up to > 97 vol% CO2, while recovering at least 95% of it, which corresponds to removing 4.0 kg/day of CO2. …

The Poverty Obliteration Program, Robertico Croes, Manuel Rivera

Faculty Scholarship and Creative Works

The complexity of the concept of poverty is revealed through multiple channels in politics, media, and associations, and the international community. Different views and positions are adopted with regard to the meaning, causes and approaches to poverty. This diversity in definitions poses enormous hurdles for realizing the perennial objective of reducing poverty by modern society. Varying conceptualizations of poverty make measurements controversial, affecting estimates of the magnitude of poverty and subsequent actions to be undertaken. Conflicting notions of poverty can leave poor people without the necessary policy attention and actions. This chapter explores the meanings and measurements of poverty and …

Land Use In The Northern Great Plains Region Of The U.S. Influences The Survival And Productivity Of Honey Bee Colonies, Matthew D. Smart, Jeff S. Pettis, Ned Euliss, Marla S. Spivak

Department of Entomology: Faculty Publications

The Northern Great Plains region of the US annually hosts a large portion of commercially managed U.S. honey bee colonies each summer. Changing land use patterns over the last several decades have contributed to declines in the availability of bee forage across the region, and the future sustainability of the region to support honey bee colonies is unclear. We examined the influence of varying land use on the survivorship and productivity of honey bee colonies located in six apiaries within the Northern Great Plains state of North Dakota, an area of intensive agriculture and high density of beekeeping operations. Land …

Linking Measures Of Colony And Individual Honey Bee Health To Survival Among Apiaries Exposed To Varying Agricultural Land Use, Matthew D. Smart, Jeff Pettis, Nathan Rice, Zac Browning, Marla Spivak

Department of Entomology: Faculty Publications

We previously characterized and quantified the influence of land use on survival and productivity of colonies positioned in six apiaries and found that colonies in apiaries surrounded by more land in uncultivated forage experienced greater annual survival, and generally more honey production. Here, detailed metrics of honey bee health were assessed over three years in colonies positioned in the same six apiaries. The colonies were located in North Dakota during the summer months and were transported to California for almond pollination every winter. Our aim was to identify relationships among measures of colony and individual bee health that impacted and …

Spodoptera litura F. (Lepidoptera: Noctuidae) adversely affects important crops such as cotton, okra, tomato, potato, and pumpkin. For the first time, this species was observed in a citrus nursery in the Sargodha Region of Pakistan. The principal objectives of this study were to determine the effects of several citrus (Sapindales: Rutaceae) cultivars, including Citrus reticulata Blanco (Feutrell’s Early, Seedless Kinnow, and Fairchild mandarin orange) and Citrus paradisi Macfad. (grapefruit), on feeding by S. litura, and the effects of these plants on the growth of the insect. Based on performance of 3rd instars, Feutrell’s Early and Seedless Kinnow supported maximum …

Honey Bee Gut Microbiome Is Altered By In-Hive Pesticide Exposures, Madhavi L. Kakumanu, Alison M. Reeves, Troy D. Anderson, Richard R. Rodrigues, Mark A. Williams

Department of Entomology: Faculty Publications

Honey bees (Apismellifera) are the primary pollinators of major horticultural crops. Over the last few decades, a substantial decline in honey bees and their colonies have been reported. While a plethora of factors could contribute to the putative decline, pathogens, and pesticides are common concerns that draw attention. In addition to potential direct effects on honey bees, indirect pesticide effects could include alteration of essential gut microbial communities and symbionts that are important to honey bee health (e.g.,immunesystem). The primary objective of this study was to determine the microbiome associated with honey bees exposed to commonly used in-hive …

Effects Of Pesticide Treatments On Nutrient Levels In Worker Honey Bees (Apis Mellifera), Haley K. Feazel-Orr, Katelyn M. Catalfamo, Carlyle C. Brewster, Richard D. Fell, Troy D. Anderson, Breanna E. Traver

Department of Entomology: Faculty Publications

Honey bee colony loss continues to be an issue and no factor has been singled out as to the cause. In this study, we sought to determine whether two beekeeper-applied pesticide products, tau-fluvalinate and Fumagilin-B, and one agrochemical, chlorothalonil, impact the nutrient levels in honey bee workers in a natural colony environment. Treatments were performed in-hive and at three different periods (fall, spring, and summer) over the course of one year. Bees were sampled both at pre-treatment and two and four weeks post-treatment, weighed, and their protein and carbohydrate levels were determined using BCA and anthrone based biochemical assays, respectively. …

Tolerance Of Ks-4202 Soybean To The Attack Of Bemisia Tabaci Biotype B (Hemiptera: Aleyrodidae), Patrícia L. Cruz, Edson L.L. Baldin, Leysimar R.P. Guimarães, Luiz E.R. Pannuti, Giuseppina P.P. Lima, Tiffany Heng-Moss, Thomas E. Hunt

Department of Entomology: Faculty Publications

Bemisia tabaci (Gennadius) biotype B (Hemiptera: Aleyrodidae) is considered one of the most important pests of soybean, Glycine max L. (Merrill) (Fabaceae), in Brazil and worldwide. Although chemical control still represents the principal strategy used to control this insect, less aggressive strategies such as the use of resistant genotypes stand out as potentially efficient alternatives for integrated pest management programs. This study aimed to evaluate the possible occurrence of tolerance to B. tabaci biotype B in the ‘KS-4202’ soybean genotype, which is already recognized as tolerant to Aphis glycines Matsumura (Hemiptera: Aphididae) in the United States. The ‘Conquista’ Brazilian cultivar …

Biology And Economics Of Recommendations For Insecticide-Based Management Of Soybean Aphid, Robert L. Koch, Bruce D. Potter, Phillip A. Glogoza, Erin W. Hodgson, Christian H. Krupke, John F.

Soybean aphid, Aphis glycines Matsumura, remains the key insect pest of soybean, Glycine max (L.) Merrill, in the north-central United States. Management of this pest has relied primarily on scouting and application of foliar insecticides based on an economic threshold (ET) of 250 aphids per plant. This review explains why this ET remains valid for soybean aphid management, despite changes in crop value and input costs. In particular, we review how soybean aphid impacts soybean yield, the role of biology and economics in recommendations for soybean aphid management, and the short- and long-term consequences of inappropriately timed insecticide applications.

Department of Electrical and Computer Engineering: Faculty Publications

The relationship between the host and its microbiota is challenging to understand because both microbial communities and their environments are highly variable. We have developed a set of techniques based on population dynamics and information theory to address this challenge. These methods identify additional bacterial taxa associated with pediatric Crohn disease and can detect significant changes in microbial communities with fewer samples than previous statistical approaches required. We have also substantially improved the accuracy of the diagnosis based on the microbiota from stool samples, and we found that the ecological niche of a microbe predicts its role in Crohn disease. …

Emergence Of A Potent Multidrug Efflux Pump Variant That Enhances Campylobacter Resistance To Multiple Antibiotics, Hong Yao, Zhangql Shen, Yang Wang, Fengru Deng, Dejun Liu, Gaowa Naren, Lel Dal, Chih-Chia Su, Bing Wang, Shaolin Wang, Congming Wu, Edward W. Yu, Qijing Zhang, Jianzhong Shen

Department of Food Science and Technology: Faculty Publications

Bacterial antibiotic efflux pumps are key players in antibiotic resistance. Although their role in conferring multidrug resistance is well documented, the emergence of “super” efflux pump variants that enhance bacterial resistance to multiple drugs has not been reported. Here, we describe the emergence of a resistance-enhancing variant (named RE-CmeABC) of the predominant efflux pump CmeABC in Campylobacter, a major zoonotic pathogen whose resistance to antibiotics is considered a serious antibiotic resistance threat in the United States. Compared to the previously characterized CmeABC transporters, RECmeABC is much more potent in conferring Campylobacter resistance to antibiotics, which was shown by increased …

Koppelman

Department of Food Science and Technology: Faculty Publications

Conglutins represent the major peanut allergens and are renowned for their resistance to gastrointestinal digestion. Our aim was to characterize the digestion-resistant peptides (DRPs) of conglutins by biochemical and biophysical methods followed by a molecular dynamics simulation in order to better understand the molecular basis of food protein allergenicity. We have mapped proteolysis sites at the N- and C-termini and at a limited internal segment, while other potential proteolysis sites remained unaffected. Molecular dynamics simulation showed that proteolysis only occurred in the vibrant regions of the proteins. DRPs appeared to be conformationally stable as intact conglutins. Also, the overall secondary …

Battle In The New World: Helicoverpa Armigera Versus Helicoverpa Zea (Lepidoptera: Noctuidae), José P. F. Bentivenha, Silvana L. Vieira De Paula Moraes, Edson L. L. Baldin, Alexandre Specht, Ivana F. Da Silva, Thomas E. Hunt

Department of Entomology: Faculty Publications

The corn earworm Helicoverpa zea (Boddie) and the old world bollworm H. armigera (HuÈbner) (Lepidoptera: Noctuidae) are allopatric species and occur in important agricultural crops. In maize, both species tend to infest the ear. The introduction of H. armigera in Brazil has created a new scenario, where these Helicoverpa species might cohabit and interact with one another, affecting the prevalence of each species in the agroecosystem, integrated pest management, and insect resistance management. In this study, larval occurrence and proportion of these species in maize was assessed in three regions of Brazil during three crop seasons. Interaction between …

Prebiotics And Synbiotics: Dietary Strategies For Improving Gut Health, Janina A. Krumbeck, Maria X. Maldonado-Gomez, Amanda E. Ramer-Tait, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Purpose of review — A wide range of dietary carbohydrates, including prebiotic food ingredients, fermentable fibers, and milk oligosaccharides, are able to produce significant changes in the intestinal microbiota. These shifts in the microbial community are often characterized by increased levels of bifidobacteria and lactobacilli. More recent studies have revealed that species of Faecalibacterium, Akkermansia, and other less well studied members may also be enriched. We review the implications of these recent studies on future design of prebiotics and synbiotics to promote gastrointestinal health.

Recent findings — Investigations assessing the clinical outcomes associated with dietary modification of the …
