Effect Of Coccidiodomycosis In Livestock, Robert Wood

Midsouth Entomologist

Coccidioidomycosis, also known as Valley Fever, is a fungal infection that affects most mammals. It is found throughout the semi-arid parts of the Americas. Valley Fever was first described in 1892 as a parasitic disease with high mortality and morbidity, but is now considered to be a low morbidity and mortality fungal disease. Although the disease could have long lasting effects that ultimately lead to death, likelihood of mortality is low. Additionally, morbidity is reduced with appropriate treatment.

Faculty Publications

The presence of domoic acid (DA) toxin from multiple species of Pseudo-nitzschia is a concern in the highly productive food webs of the northern 1,* 2,3 2 1 1,4 1 1 2 3 4 Gulf of Mexico. We documented the Pseudo-­nitzschia presence, abundance, blooms, and toxicity over 3 years along a transect ∼100 km west of the Mississippi River Delta on the continental shelf. Pseudo-nitzschia were present throughout the year and occurred in high abundances (>10 cells l ) in the early spring months during high Mississippi River (MSR) flow (∼20,000 m s ) but were most abundant ( …

Creation Of A New Type Of Ion Exchange Material For Rapid, High-Capacity, Reversible And Selective Ion Exchange Without Swelling And Entrainment, Baiyan Li, Yiming Zhang, Dingxuan Ma, Zhenyu Xing, Tianliang Ma, Zhan Shi, Xiulei Ji, Shengqian Ma

Chemistry Faculty Publications

Ion-exchange materials, currently dominated by resins, are widely used in a plethora of areas. However, the drawbacks of conventional resins necessitate the creation of a new model of ion exchange materials that feature controllable swelling, easily accessible ion exchange sites, high ion exchange capacity, fast ion exchange kinetics, and high chemical stability as illustrated herein in the context of functionalizing a porous organic polymer (POP) with ion exchange groups. The advantages of POP-based ion exchange materials in comparison with conventional resins and other types of ion exchange materials have been highlighted through an evaluation of their performances in scavenging precious …

Development And Application Of New Solid-State Models For Low-Energy Vibrations, Lattice Defects, Entropies Of Mixing, And Magnetic Properties, Jacob M. Schliesser

Theses and Dissertations

Low-temperature heat capacity data contain information on the physical properties of materials, and new models continue to be developed to aid in the analysis and interpretation of heat capacity data into physically meaningful properties. This work presents the development of two such models and their application to real material systems. Equations describing low-energy vibrational modes with a gap in the density of states (DOS) have been derived and tested on several material systems with known gaps in the DOS, and the origins of such gaps in the DOS are presented. Lattice vacancies have been shown to produce a two-level system …

Transcriptional Profile Of Immediate Response To Ionizing Radiation Exposure, Eric C. Rouchka, Robert M. Flight, Brigitte H. Fasciotto, Rosendo Estrada, John W. Eaton, Phani K. Patibandla, Sabine J. Waigel, Dazhuo Li, John K. Kirtley, Palaniappan Sethu, Robert S. Keynton

Astronauts participating in long duration space missions are likely to be exposed to ionizing radiation associated with highly energetic and charged heavy particles. Previously proposed gene biomarkers for radiation exposure include phosphorylated H2A Histone Family, Member X (γH2AX), Tumor Protein 53 (TP53), and Cyclin-Dependent Kinase Inhibitor 1A (CDKN1A). However, transcripts of these genes may not be the most suitable biomarkers for radiation exposure due to a lack of sensitivity or specificity. As part of a larger effort to develop lab-on-a-chip methods for detecting radiation exposure events using blood samples, we designed a dose–course microarray study in order to determine coding …

Pressure To Publish For Residency Applicants In Dermatology, Jordan V. Wang, Matthew S. Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

As it grows increasingly difficult to match into a dermatology residency program each year, there is a widening gap in research accomplishments between those who have and have not matched successfully. Applicants should be aware of the current trends in order to maximize their chances of matching. Such research inequality may subsequently lead to increases in the pressure to publish and the incidence of academic misrepresentation. Academic dermatology programs should be aware of these issues in order to help their students successfully match and exercise caution when reviewing the curricula vitae of applicants. We believe that student mentors in dermatology …

Analysis Of The Invasiveness Of Cabomba Caroliniana A. Gray In Massachusetts And Rhode Island Freshwater Lakes And Assessment Of The Impacts Of Local Community Action Groups On Ais Management And Intervention Programs, Nicole Cournoyer

Master of Science in Global Environmental Studies

Native to parts of South America and southeastern United States, Cabomba caroliniana A. Gray is an invasive aquatic pondweed species that has migrated to northern regions of the United States. C. caroliniana is known for its rapid growth pattern and its ability to dominate freshwater ecosystems. The overgrowth of this invasive species is difficult to manage, with few effective eradication/control methods available. Dense hairs and crystals found upon the leaf surfaces are believed to enhance the ability of Carolina fanwort to survive in a wide variety of ecosystems. Management of this particular species requires an active approach. This study explored …

Methods For Detecting Microbial Methane Production And Consumption By Gas Chromatography, Jared T. Aldridge, Jennie L. Catlett, Megan L. Smith, Nicole R. Buan

Department of Biochemistry: Faculty Publications

Methane is an energy-dense fuel but is also a greenhouse gas 25 times more detrimental to the environment than CO2. Methane can be produced abiotically by serpentinization, chemically by Sabatier or Fisher-Tropsh chemistry, or biotically by microbes (Berndt et al., 1996; Horita and Berndt, 1999; Dry, 2002; Wolfe, 1982; Thauer, 1998; Metcalf et al., 2002). Methanogens are anaerobic archaea that grow by producing methane gas as a metabolic byproduct (Wolfe, 1982; Thauer, 1998). Our lab has developed and optimized three different gas chromatograph-utilizing assays to characterize methanogen metabolism (Catlett et al., 2015). Here we describe the end point and kinetic …

Challenges And Opportunities In The Culture Of Giant Freshwater Prawn In The Philippines, Janice A. Ragaza

Biology Faculty Publications

Amid the irremediable decline of capture fisheries, the Philippine government has identified aquaculture as a sector that will ensure food security and generate new job opportunities geared toward the country’s goal of economic development (Nagothu and Ortiz 2007). Aquaculture of giant freshwater prawn Macrobrachium rosenbergii (Fig. 1) is an emerging program that is intended to expand and vary the aquatic species used in freshwater aquaculture, which is still predominantly based on tilapia (Rosario and Tayamen 2004). Attractive characteristics of freshwater prawn culture include ease of breeding, high hatching rate, superior quality of meat and high market value (Keysami and Mohammadpour …

Stabilization Of Microtubule-Unbound Tau Via Tau Phosphorylation At Ser262/356 By Par-1/Mark Contributes To Augmentation Of Ad-Related Phosphorylation And Aβ42-Induced Tau Toxicity., Kanae Iijima-Ando, Akiko Maruko-Otake, Yosuke Ohtake, Motoki Hayashishita, Michiko Sekiya, Koichi M Iijima

Department of Neuroscience Faculty Papers

Abnormal accumulation of the microtubule-interacting protein tau is associated with neurodegenerative diseases including Alzheimer's disease (AD). β-amyloid (Aβ) lies upstream of abnormal tau behavior, including detachment from microtubules, phosphorylation at several disease-specific sites, and self-aggregation into toxic tau species in AD brains. To prevent the cascade of events leading to neurodegeneration in AD, it is essential to elucidate the mechanisms underlying the initial events of tau mismetabolism. Currently, however, these mechanisms remain unclear. In this study, using transgenic Drosophila co-expressing human tau and Aβ, we found that tau phosphorylation at AD-related Ser262/356 stabilized microtubule-unbound tau in the early phase of …

Combined Effects Of Pesticides And Trematode Infections On Hourglass Tree Frog Polypedates Cruciger., Uthpala A. Jayawardena, Jason R. Rohr, Ayanthi N. Navaratne, Priyanie H. Amerasinghe, Rupika S. Rajakaruna

Integrative Biology Faculty and Staff Publications

The impact of widespread and common environmental factors, such as chemical contaminants, on infectious disease risk in amphibians is particularly important because both chemical contaminants and infectious disease have been implicated in worldwide amphibian declines. Here we report on the lone and combined effects of exposure to parasitic cercariae (larval stage) of the digenetic trematode, Acanthostomum burminis, and four commonly used pesticides (insecticides: chlorpyrifos, dimethoate; herbicides: glyphosate, propanil) at ecologically relevant concentrations on the survival, growth, and development of the common hourglass tree frog, Polypedates cruciger Blyth 1852. There was no evidence of any pesticide-induced mortality on cercariae because all …

Resolving Conflicts Over Scarce Resources: Private Versus Shared Ownership, W.C. Bunting

Marquette Law Review

This Article models private ownership as a conflict resolution mechanism and contends that for the Coase Theorem, as narrowly defined in this Article, to be consistent, private ownership must yield the Pareto- optimal use of scarce resources among all feasible conflict resolution mechanisms. Conflict over a scarce resource may be better resolved, however, by eliminating the possibility of private ownership and “forcing” disputing parties to share ownership of the contested resource. A corollary to the Coase Theorem is introduced which states: In the absence of transaction costs, the distribution of private and shared ownership is efficient. Further, assuming transaction costs …

Price-Level Regulation And Its Reform, James Ming Chen

Marquette Law Review

Price-level, or “price-cap,” regulation offers an alluring alternative to the traditional technique of monitoring a regulated firm’s profits. This Article contrasts price-level regulation with conventional cost-of-service ratemaking and with Ramsey pricing. Price-level regulation stands as a market-based, incentive-driven “third way” between traditional regulation and complete deregulation. Although some jurisdictions have set price caps according to operating cost and rate-of-return calculations that clearly parallel those steps in conventional ratemaking, this Article will focus on price-level methodologies that combine an economy-wide measure of inflation with an x-factor reflecting total factor productivity within a regulated industry.

After addressing the simpler component of price-level …

References To Television Programming In Judicial Opinions And Lawyers’ Advocacy, Douglas E. Abrams

Marquette Law Review

“Think of the poor judge who is reading . . . hundreds and hundreds of these briefs,” says Chief Justice John G. Roberts, Jr. “Liven their life up just a little bit . . . with something interesting.”

Lawyers can “liven up” their briefs with references to television shows generally known to Americans who have grown up watching the small screen. After discussing television’s pervasive effect on American culture since the early 1950s, this Article surveys the array of television references that appear in federal and state judicial opinions. In cases with no claims or defenses concerning the television industry, …

Trends, Causal Analysis, And Recommendations From 14 Years Of Ferry Accidents, Abigail S. Golden, Roberta E. Weisbrod

Journal of Public Transportation

Ferries and other passenger vessels provide a crucial mode of transportation for many in the developing world, especially in archipelagic nations like Indonesia and in river delta nations like Bangladesh. However, this dependence on passenger vessels coincides with a high rate of accidents and fatalities in many countries, linked to purchase of old, substandard, and/or inappropriate vessels in low-income nations; overcrowding; inadequate training; and sudden hazardous weather. Any serious attempt to decrease the number and fatality count of ferry accidents in the developing world must have a complete record of past incidents on which to draw. This report compiles detailed …

Simulating Electric Charges And Electric Force In Android, Arlind Hajredinaj

Theses and Dissertations

Simulating physics phenomena is somewhat complicated, depending on what is to be simulated, the laws, the amount of space, the time. It all breaks down to the scale of the universe that we are going to simulate, we might want to draw objects, which means we need a screen that has pixels, a pixel size can be a meter, half a meter, millimeter or down to the smallest distance the Planck length which is 1.616199(97)×10⁻³⁵, we can simulate Newtonian laws, laws of Thermodynamics, theory of relativity, particles of light and such, the more physics we want to add …

Trail Planning, Jayoung Koo

Agriculture and Natural Resources Publications

There are two general ways to begin a trail project in a community. The first method is for the community (client) to hire design or planning professionals such as landscape architects, urban planners or engineers to lead a trail project on behalf of the community. The second way involves a grass roots approach where a community gets the project started and develops the conceptual ideas on their own and then later brings in professionals during the design phase. Regardless of the approach for the initial phase, professionals need to be involved to eventually construct the trail(s) but how much of …

Genetically Engineered Crops: Emerging Opportunities, Paul C. Vincelli

Agriculture and Natural Resources Publications

Biotechnology is “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.” This definition encompasses many, many applications, including traditional ones such as fermentation of alcoholic beverages.

In certain biotech crops, their genetic material (DNA) has been purposefully manipulated in the laboratory. These genetically engineered crops are often called “GMOs,” an acronym for “genetically modified organisms.” These GMOs are the focus of this publication.

Plant Diseases [2016], Kimberly Leonberger, Kelly Jackson, Robbie Smith, Nicole Ward Gauthier

Agriculture and Natural Resources Publications

Anyone who has ever planted a garden knows not only the rewards of beautiful flowers, fruit, and/ or vegetables, but also the disappointment when plants become diseased or damaged. Many factors cause plants to exhibit poor vigor, changes in appearance, or even death. Both abiotic (non-living) and biotic (living) factors can negatively impact plant heath. Disorders that result from non-living factors (such as nutrient deficiencies, over/under watering, temperature stress, and chemical damage) are discussed in subsequent chapters. This chapter focuses on those living organisms that cause disease: fungi, water molds, bacteria, viruses, nematodes, phytoplasmas, and parasitic plants.

Associations Between Ectomycorrhizal Fungi And Bacterial Needle Endophytes In Pinus Radiata: Implications For Biotic Selection Of Microbial Communities, Megan A. Rúa, Emily C. Wilson, Sarah Steele, Arielle R. Munters, Jason D. Hoeksema, Anna C. Frank

Biological Sciences Faculty Publications

Studies of the ecological and evolutionary relationships between plants and their associated microbes have long been focused on single microbes, or single microbial guilds, but in reality, plants associate with a diverse array of microbes from a varied set of guilds. As such, multitrophic interactions among plant-associated microbes from multiple guilds represent an area of developing research, and can reveal how complex microbial communities are structured around plants. Interactions between coniferous plants and their associated microbes provide a good model system for such studies, as conifers host a suite of microorganisms including mutualistic ectomycorrhizal (ECM) fungi and foliar bacterial endophytes. …
