The Role Of Adaptive Immunity In Chronic Hypoxia-Induced Pulmonary Hypertension, Levi David Maston

Biomedical Sciences ETDs

Inflammation is a prominent pathologic feature in pulmonary arterial hypertension as demonstrated by pulmonary vascular infiltration of inflammatory cells, including T and B lymphocytes. However, the contribution of the adaptive immune system is not well characterized in pulmonary hypertension (PH) caused by chronic hypoxia (CH). Inflammatory cells, through various mechanisms, have the capability to increase pulmonary vascular resistance in various disease states. CD4⁺T cells have the potential to play a significant role in the disease process initiated by hypoxia. CD4⁺T cells are largely responsible for orchestrating downstream immune processes and are critical in focusing and amplifying …

Prophylactic Effects Of Isomaltodextrin In A Balb/C Mouse Model Of Egg Allergy, Yoshinori Mine, Yan Jin, Hua Zhang, Prithy Rupa, Kaustav Majumder, Takeo Sakurai, Yoshifumi Taniguchi, Ryodai Takagaki, Hikaru Watanabe, Hitoshi Mitsuzumi

Department of Food Science and Technology: Faculty Publications

The aim of this study was to evaluate the potential effects of isomaltodextrin (IMD), a dietary saccharide polymer derived from enzymatically produced from starch, on the ability to alter immune response (IR) bias to hen egg ovalbumin (Ova) induced allergic inflammation in mice. Groups of Balb/c mice were pre-treated with various doses of IMD in drinking water (1.0, 2.5, and 5.0% w/v) for 6 weeks and subsequently sensitized to the Ova together with continuous administration of IMD. To evaluate changes in immune response bias, immunoglobulin isotype-associated antibody activity, concentrations of type 1 and 2 cytokines and the percentage of T-regulatory …

Impact Of The Human Footprint On Anthropogenic Mortality Of North American Reptiles, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

United States Department of Agriculture Wildlife Services: Staff Publications

Human activities frequently result in reptile mortality, but how direct anthropogenic mortality compares to natural morality has not been thoroughly investigated. There has also been a limited examination of how anthropogenic reptile mortality changes as a function of the human footprint. We conducted a synthesis of causespecific North American reptile mortality studies based on telemetry, documenting 550 mortalities of known cause among 2461 monitored individuals in 57 studies. Overall 78% of mortality was the result of direct natural causes, whereas 22% was directly caused by humans. The single largest source of mortality was predation, accounting for 62% of mortality overall. …

Divergent Selection And Primary Gene Flow Shape Incipient Speciation Of A Riparian Tree On Hawaii Island, Jae Young Choi, Michael Purugganan, Elizabeth A. Stacy

Life Sciences Faculty Research

A long-standing goal of evolutionary biology is to understand the mechanisms underlying the formation of species. Of particular interest is whether or not speciation can occur in the presence of gene flow and without a period of physical isolation. Here, we investigated this process within Hawaiian Metrosideros, a hypervariable and highly dispersible woody species complex that dominates the Hawaiian Islands in continuous stands. Specifically, we investigated the origin of Metrosideros polymorpha var. newellii (newellii), a riparian ecotype endemic to Hawaii Island that is purportedly derived from the archipelago-wide M. polymorpha var. glaberrima (glaberrima). Disruptive selection across a sharp forestriparian ecotone …

Phytoplankton Community And Algal Toxicity At A Recurring Bloom In Sullivan Bay, Kabetogama Lake, Minnesota, Usa, Victoria G. Christensen, Ryan P. Maki, Erin A. Stelzer, Jack E. Norlan, Eakalak Khan

Civil and Environmental Engineering and Construction Faculty Research

Kabetogama Lake in Voyageurs National Park, Minnesota, USA suffers from recurring late summer algal blooms that often contain toxin-producing cyanobacteria. Previous research identified the toxin microcystin in blooms, but we wanted to better understand how the algal and cyanobacterial community changed throughout an open water season and how changes in community structure were related to toxin production. Therefore, we sampled one recurring bloom location throughout the entire open water season. The uniqueness of this study is the absence of urban and agricultural nutrient sources, the remote location, and the collection of samples before any visible blooms were present. Through quantitative …

An Autobiographical Narrative Of A Principal's Personal Journey With Autonomy, Delilah Rabeiro

USF Tampa Graduate Theses and Dissertations

Educational reform and state policies have stripped principals and teachers of autonomy, and this has been attributed as one of the reasons why teachers leave the profession. Adamson (2012) stated, "To implement reform at their school sites, principals need a certain degree of autonomy. This study sought to understand what I experienced of autonomy as I embarked on my journey as a principal of a turnaround school; what I did, or did not do, to extend autonomy to teachers; and what I came understand about autonomy in this turnaround setting.

This was an autobiographical narrative inquiry (Freeman, 2007; Saleh, Menon, …

Effect Of Biosurfactant And Biochar On Ecosystem Functions And Oil Remediation In Crude Oil Contaminated Wetland Soils, Zhuo Wei

LSU Doctoral Dissertations

Decontamination of oil spill from coastal wetland soils requires a delicate approach. Remediation strategies using biochar, biosurfactant, and nutrient additions have been proposed. However, there is little information on application of these with combination for treatment of crude oil-contaminated wetland soil. Therefore, incubation studies were carried out to investigate the impact of biochar and rhamnolipid (RL) biosurfactant along with nitrogen (N) application on petroleum hydrocarbon degradation in a Louisiana coastal saline marsh and their impacts on greenhouse gas (GHG) emission. Additionally, the toxicity of crude oil as well as remediation materials on coastal wetland ecosystem were assessed at three levels: …

Evaluation Of Metsulfuron-Methyl For Giant Salvinia (Salvinia Molesta) Control And Non-Target Species Sensitivity, William Prevost

LSU Master's Theses

The invasive aquatic fern giant salvinia (Salvinia molesta D.S. Mitchell) has been invading waterbodies across Louisiana and Texas since 1998. Recently, the non-aquatic herbicide metsulfuron-methyl was found to be highly efficacious against giant salvinia, but limited information is available on application techniques, use rates and concentrations, as well as its impact on non-target species. Therefore, a series of mesocosm experiments were conducted to further evaluate foliar and subsurface applications of metsulfuron against giant salvinia, as well as foliar applications of metsulfuron in combination with aquatic herbicides commonly used for giant salvinia control. When applied to the foliage of giant …

Rice Response To Nitrogen Fertilization And Comparison Of Unmanned Aerial Systems And Active Crop Canopy Sensors Vegetative Index To Estimate Rice Yield Potential, Anna Coker

LSU Master's Theses

Nitrogen (N) fertilization is a key component in producing profitable, maximized rice grain yields because yield is directly affected by N fertilizer applications. Economical optimum N rate (EONR) is used to estimate where the N fertilization rate impacts rice grain yield but is still economically efficient. Three common response models, linear-plateau, quadratic-plateau, and quadratic models were used to determine the response of rice to N fertilizer to determine the optimum N fertilization rate. The objective of the first part of this study was to evaluate the models by assessing the coefficients of determination (R²), maximum rice grain yields …

Sandy Dredge Pit Sedimentation – Characteristics And Processes In Caminada Borrow Area, Ship Shoal, Louisiana Shelf, Usa, Zehao Xue

LSU Master's Theses

Mississippi River Deltaic Plain’s barrier islands are undergoing rapid disintegration due to high rates of subsidence and a deficit in coastal sediment supply. To mitigate for barrier island land loss, Louisiana has implemented a restoration program that supplements coastal sediment deficits by introducing sand from outside of the active coastal system. Ship Shoal is an inner-shelf submarine shoal with large amounts of restoration quality sand that was dredged in 2013-2016 for the Caminada Headland Restoration Project in central Louisiana, USA.

Vibracore samples (1.5 - 3.5 m deep) collected in 2017 and 2018 in Caminada Borrow Area revealed new silts and …

Immune Gene Diversity And Populations Structure Of Reticulated Flatwoods Salamander (Ambystoma Bishopi), Steven Tyler Williams

LSU Master's Theses

Reticulated flatwoods salamander (Ambystoma bishopi) populations began decreasing dramatically in the late 1900s. Contemporary populations are small, isolated, and may be susceptible to inbreeding and reduced adaptive potential because of low genetic variation. Genetic variation at immune genes is especially important as it influences disease susceptibility and adaptation to emerging infectious pathogens, a central conservation concern for declining amphibians. Connectivity between isolated populations is also vital to maintain genetic diversity and avoid inbreeding. I collected tissue samples from across the extant range of this salamander to examine genetic variation and population structure in: immune genes broadly (immunome), the …

Investigating The Mechanisms Of Hydrolysis And Amyloidosis Through Computational Approaches, Gaurav Sharma

Open Access Dissertations

Hydrolysis reaction is involved in a wide range of biological and industrial applications. In our body, phosphoester and peptide hydrolysis are accomplished using specialized enzymes known as phosphoesterases and proteases. These enzymes constitute about 60% of all the enzymes that are used today in textile, food, leather, paper, and ethanol production industries.In this thesis, I have focused on the following three projects; (1) exploring the interactions of various biomolecules (such as enzymes, antimicrobial peptides, DNA, and amyloid β fibrils) with their binding molecules; (2) understanding the mechanism of phosphoester and peptide hydrolysis by glycerophosphodiesterase (GpdQ) and Streptomyces griseus aminopeptidase (SgAP), …

Developing And Optimizing Shrub Parameters Representing Sagebrush (Artemisia Spp.) Ecosystems In The Northern Great Basin Using The Ecosystem Demography (Edv2.2) Model, Karun Pandit, Hamid Dashti, Nancy F. Glenn, Alejandro N. Flores

Geosciences Faculty Publications and Presentations

Ecosystem dynamic models are useful for understanding ecosystem characteristics over time and space because of their efficiency over direct field measurements and applicability to broad spatial extents. Their application, however, is challenging due to internal model uncertainties and complexities arising from distinct qualities of the ecosystems being analyzed. The sagebrush-steppe ecosystem in western North America, for example, has substantial spatial and temporal heterogeneity as well as variability due to anthropogenic disturbance, invasive species, climate change, and altered fire regimes, which collectively make modeling dynamic ecosystem processes difficult. Ecosystem Demography (EDv2.2) is a robust ecosystem dynamic model, initially developed for tropical …

The Why, When, And How Of Computing In Biology Classrooms [Version 1; Peer Review: 2 Approved], April M. Wright, Rachel Schwartz, Jamie R. Oaks, Catherine E. Newman, Sarah P. Flanagan

Biological Sciences Faculty Publications

Many biologists are interested in teaching computing skills or using computing in the classroom, despite not being formally trained in these skills themselves. Thus biologists may find themselves researching how to teach these skills, and therefore many individuals are individually attempting to discover resources and methods to do so. Recent years have seen an expansion of new technologies to assist in delivering course content interactively. Educational research provides insights into how learners absorb and process information during interactive learning. In this review, we discuss the value of teaching foundational computing skills to biologists, and strategies and tools to do so. …

Nuclear Ban Treaty And The Southern Asian ‘Nuclear Troika’, Sitakanta Mishra

International Journal of Nuclear Security

Of late, nuclear weapons have been multilaterally outlawed similar to the other weapons of mass destruction. But the nuclear weapon states, barring North Korea, and the sole victim of nuclear weapons Japan, have remained outside the treaty process. This does expose the usual clarion call of the nuclear weapon states for nuclear disarmament and non-proliferation. This study attempts to enquire the policy approach of the three nuclear weapon states in Southern Asia – China, India and Pakistan who proclaim themselves as ‘responsible’ nuclear states – regarding the ban treaty comparatively. While China’s stated position seem to be based more on …

Changes To North American Butterfly Names, Jing Zhang, Qian Cong, Jinhui Shen, Paul A. Opler, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

We obtained and analyzed whole genome shotgun sequences of all 845 species of butterflies recorded from Canada and the United States. Genome-scale phylogenetic trees constructed from the data reveal several nonmonophyletic genera and suggest improved classification of species included in these genera. Here, these changes are formalized and 2 subgenera are described: Amblyteria Grishin, subgen. n. (type species Goniloba exoteria Herrich-Schäffer, 1869, parent genus Amblyscirtes Scudder, 1872), and Coa Grishin, subgen. n. (type species Hesperia baracoa Lucas, 1857, parent genus Polites Scudder, 1872). Furthermore, we resurrect 3 genera and 2 subgenera from synonymy, change the rank of 6 currently used …

A Deda Family Membrane Protein Is Required For Burkholderia Thailandensis Colistin Resistance, Pradip R. Panta, Sujeet Kumar, Caroline F. Stafford, Caitlin E. Billiot, Martin V. Douglass, Carmen M. Herrera, M. Stephen Trent, William T. Doerrler

Faculty Publications

© Copyright © 2019 Panta, Kumar, Stafford, Billiot, Douglass, Herrera, Trent and Doerrler. Colistin is a “last resort” antibiotic for treatment of infections caused by some multidrug resistant Gram-negative bacterial pathogens. Resistance to colistin varies between bacterial species. Some Gram-negative bacteria such as Burkholderia spp. are intrinsically resistant to very high levels of colistin with minimal inhibitory concentrations (MIC) often above 0.5 mg/ml. We have previously shown DedA family proteins YqjA and YghB are conserved membrane transporters required for alkaline tolerance and resistance to several classes of dyes and antibiotics in Escherichia coli. Here, we show that a DedA family …

Gene Expression Of Endangered Coral (Orbicella Spp.) In Flower Garden Banks National Marine Sanctuary After Hurricane Harvey, Rachel M. Wright, Adrienne M.S. Correa, Lucinda A. Quigley, Lory Z. Santiago-Vázquez, Kathryn E.F. Shamberger, Sarah W. Davies

Biological Sciences: Faculty Publications

About 190 km south of the Texas–Louisiana border, the East and West Flower Garden Banks (FGB) have maintained > 50% coral cover with infrequent and minor incidents of disease or bleaching since monitoring began in the 1970s. However, a mortality event, affecting 5.6 ha (2.6% of the area) of the East FGB, occurred in late July 2016 and coincided with storm-generated freshwater runoff extending offshore and over the reef system. To capture the immediate effects of storm-driven freshwater runoff on coral and symbiont physiology, we leveraged the heavy rainfall associated with Hurricane Harvey in late August 2017 by sampling FGB corals …
