Interspecific Differences In The Flow Regimes And Drag Of North Pacific Skate Egg Cases, Kayla C. Hall, Jaida N. Elcock, Gerald R. Hoff, Duane E. Stevenson, Adam P. Summers, Cassandra M. Donatelli

Engineering Faculty Articles and Research

Skates are a diverse group of dorso-ventrally compressed cartilaginous fishes found primarily in high-latitude seas. These slow-growing oviparous fishes deposit their fertilized eggs into cases, which then rest on the seafloor. Developing skates remain in their cases for 1-4 years after they are deposited, meaning the abiotic characteristics of the deposition sites, such as current and substrate type, must interact with the capsule in a way to promote long residency. Egg cases are morphologically variable and can be identified to species. Both the gross morphology and the microstructures of the egg case interact with substrate to determine how well a …

Pd-1/Pd-L1 Pathway: A Therapeutic Target In Cd30+ Large Cell Lymphomas, Wei Xie, L Jeffrey Medeiros, Shaoying Li, Guilin Tang, Guang Fan

Faculty, Staff and Student Publications

The programmed death-ligands, PD-L1 and PD-L2, reside on tumor cells and can bind with programmed death-1 protein (PD-1) on T-cells, resulting in tumor immune escape. PD-1 ligands are highly expressed in some CD30+ large cell lymphomas, including classic Hodgkin lymphoma (CHL), primary mediastinal large B-cell lymphoma (PMBL), Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (EBV+ DLBCL), and anaplastic large cell lymphoma (ALCL).

Chloride Channels That Mediate A Transient Nitric Oxide-Dependent Synaptic Polarity Switch In Retinal Amacrine Cells., Tyler Christopher Rodriguez

LSU Doctoral Dissertations

Cytosolic chloride (Cl^-) concentration determines whether GABAergic and glycinergic synapses are inhibitory or excitatory. Ionotropic GABA and glycine receptors passively conduct Cl­^- leading to membrane depolarization or hyperpolarization depending on the Cl^- equilibrium potential. Accordingly, the distribution of Cl^- across the plasma membrane has the potential to determine the properties of networks of retinal amacrine cells (ACs) and their postsynaptic partners. Ion channels are responsible for establishing Cl^- reversal potential. Nitric oxide (NO) is a signaling molecule that can be generated in the inner retina where ACs form synapses. We have shown that NO …

The Adaptation Of Export-Scale Urban Farmers Amid The Covid-19 Pandemic In Bandung Metropolitan, Kinanti Indah Safitri, Oekan Soekotjo Abdoellah, Budhi Gunawan, Parikesit -, Yusep Suparman, Akhmad Zainal Mubarak, Margareth Pardede

The Qualitative Report

These days, urban agriculture is more than a hobby. It has expanded into a local commercial business, even to an export scale. However, urban farmers who have commercialized their products must adapt to the COVID-19 pandemic situation, which has impacted many aspects of global life. This research used a mixed-method approach. We collected quantitative data from 107 respondents on the household commercialization index, income level, and education level of export-scale-urban farmers in the Bandung metropolitan area, West Java, Indonesia. We also used qualitative data to determine how farmers were adapting to difficult situations due to the COVID-19 pandemic. This information …

Breeding Ecology Of Mottled Ducks In Southwestern Louisiana, Elizabeth Sophia Bonczek

LSU Doctoral Dissertations

Mottled ducks are a resident species found in the southern United States that rely on coastal marsh and associated habitat to fulfill the needs of the entirety of their annual cycle. Population monitoring has revealed declines in western Gulf Coast (WGC) mottled ducks since 2008. Mottled duck populations are influenced by survival and recruitment, and changes in these factors may contribute to population declines. The overarching goal of this project was to identify the mechanisms potentially limiting WGC mottled ducks.

I captured adult female mottled ducks during molt on Rockefeller Wildlife Refuge and adjacent lands in southwestern Louisiana from 2017–2019. …

Multi-Scale Phase Separation By Explosive Percolation With Single-Chromatin Loop Resolution., Kaustav Sengupta, Michał Denkiewicz, Mateusz Chiliński, Teresa Szczepińska, Ayatullah Faruk Mollah, Sevastianos Korsak, Raissa D'Souza, Yijun Ruan, Dariusz Plewczynski

Faculty Research 2022

The 2 m-long human DNA is tightly intertwined into the cell nucleus of the size of 10 μm. The DNA packing is explained by folding of chromatin fiber. This folding leads to the formation of such hierarchical structures as: chromosomal territories, compartments; densely-packed genomic regions known as Topologically Associating Domains (TADs), or Chromatin Contact Domains (CCDs), and loops. We propose models of dynamical human genome folding into hierarchical components in human lymphoblastoid, stem cell, and fibroblast cell lines. Our models are based on explosive percolation theory. The chromosomes are modeled as graphs where CTCF chromatin loops are represented as edges. …

The Role Of Protein Palmitoylation In Two Disorders; X-Linked Intellectual Disability And Covid-19, Ahmed A. Ramadan

USF Tampa Graduate Theses and Dissertations

The spike proteins of enveloped viruses are transmembrane glycoproteins that typically undergo post-translational attachment of palmitate on cysteine residues on the cytoplasmic facing tail of the protein. The role of spike protein palmitoylation in virus biogenesis and infectivity is being actively studied as a potential target of novel antivirals. Here, we report that palmitoylation of the first five cysteine residues of the C-terminal cysteine-rich domain of the SARS-CoV-2 S protein are indispensable for infection, and palmitoylation-deficient spike mutants are defective in membrane fusion. The DHHC9 palmitoyltransferase interacts with and palmitoylates the spike protein in the ER and Golgi, and knockdown …

Plastic And Evolved Responses In The Eastern Oyster, Crassostrea Virginica, To Environmental Variation In The Northern Gulf Of Mexico, Kyle Sirovy

LSU Doctoral Dissertations

Climate change and other anthropogenic impacts are causing rapid alterations to many of the world’s most productive coastal ecosystems and there is an urgent need to understand how species will respond to these environmental changes. Organisms may respond through plasticity, evolution, or the evolution of plasticity. In this dissertation, I evaluate the role of plastic and evolved responses in the eastern oyster, Crassostrea virginica, to environmental variation in the northern Gulf of Mexico. I use comparative transcriptomics, physiology, and morphology to examine the relative contribution of plastic and evolved responses for oysters exposed to low salinity and outplant sites …

Marine & Environmental Sciences Faculty Reports

The intensity of deep-sea fisheries on the high seas and the impacts on the marine environment call for effective measures to ensure that fishing does not compromise the commitments established for protecting biodiversity in the deep ocean by the United Nations. In order to prevent significant adverse impacts (SAIs) on vulnerable marine ecosystems (VMEs), high seas fishing nations agreed to stop fishing activities where VMEs are known or likely to occur unless the fishing can be managed to prevent SAIs on VMEs. To determine whether fishing activities can be conducted in a sustainable manner that prevents impacts on VMEs, States …

Water Availability Dictates How Plant Traits Predict Demographic Rates, Alice E. Stears, Peter B. Adler, Dana M. Blumenthal, Julie A. Kray, Kevin E. Mueller

Biological, Geological, and Environmental Faculty Publications

A major goal in ecology is to make generalizable predictions of organism responses to environmental variation based on their traits. However, straightforward relationships between traits and fitness are rare and likely to vary with environmental context. Characterizing how traits mediate demographic responses to the environment may enhance the predictions of organism responses to global change. We synthesized 15 years of demographic data and species-level traits in a shortgrass steppe to determine whether the effects of leaf and root traits on growth and survival depended on seasonal water availability. We predicted that (1) species with drought-tolerant traits, such as lower leaf …

Regular surveillance is recommended, but few clinical practice guidelines transparently assess study bias, quality, and clinical utility in deriving recommendations of screening and assessment methods. The purpose of this clinical practice guideline (CPG) is to provide recommendations for the screening and assessment of CRF for health care professions treating individuals with cancer. Following best practices for development of a CPG using the Appraisal of Guidelines for Research and Evaluation (AGREE) Statement and Emergency Care Research Institute (ECRI) Guidelines Trust Scorecard, this CPG included a systematic search of the …

Perceptions And Readiness Of Foodservice Establishments At The Onset Of The Covid-19 Pandemic In Metro Manila And Region Iv-A, Philippines, Von Ryan M. Ebron, Irma U. Danao, Marie Faye R. Nguyen- Orca, Anna Teresa O. Orillo, Joyce P. Parco

Journal of Economics, Management and Agricultural Development

The study evaluated the perceptions and readiness of food business operators about COVID-19 through an online survey with respondents from Metro Manila and Region IV-A. Generally, they are knowledgeable about COVID-19 and its transmission, as reflected in their scores. The same is true about their attitude towards “new normal” practices. Years of operation, asset size, and continued operations and delivery services showed significant positive correlation with attitude scores. The resilience of some food business operators may be attributed to having more resources that enabled them to carry the added costs of what the new normal foodservice practices entailed. New normal …

Tissue Decay Tested In Modern Metasequoia Leaves: Implications For Early Diagenesis Of Leaves In Fossil Lagerstätten, Caitlyn R. Witkowski, Qin Leng, Christopher W. Reid, Liang Feng, Hong Yang

Science and Technology Department Faculty Journal Articles

Sedimentary deposits yielding extraordinarily-preserved fossils (known as Lagerstätten) may provide significant insights into the physiology and environments of ancient plants, particularly when the fossils represent their original characteristics with limited diagenetic modifications. To better understand molecular, isotopic, and morphological changes during the early stages of diagenesis, degradation experiments were conducted in two time series: 1) a laboratory decay series using fungi on leaves over the course of a month and 2) a natural decay series with leaves collected from different stages of leaf senescence and early diagenesis. Both experiments used modern leaves of the dawn redwood Metasequoia glyptostroboides …

International Rice Outlook: International Rice Baseline Projections 2021–2031, A. Durand-Morat, S. Bairagi

AAES Research Reports and Research Bulletins

The war in Ukraine and the lingering effects of the COVID-19 pandemic are pushing input costs to record levels. Although rice prices have increased some in the last several months, production costs have increased more than proportionally, undermining rice profitability.

We project global rice production will surpass global rice consumption for most of the coming decade, with a small deficit developing by the end of the projected period.

The projected growth in production is almost exclusively due to productivity gains since the global rice area is projected to increase only marginally by 2029–2031.

The projected growth in global rice consumption …

Monitoring Whitebark Pine Stand Health In The Central Washington Cascades, Nancy H. Parra, Teresa J. Lorenz, Taza D. Schaming, Alison Scoville

Student Published Works

Whitebark pine (Pinus albicaulis) plays a vital role in colonizing newly disturbed areas, providing shade for other tree species to germinate, and supplying food for a variety of birds and mammals, such as Clark’s Nutcrackers (Nucifraga columbiana) and grizzly bears (Ursus arctos horribilis). Decline of whitebark pine populations has been attributed to several factors, including white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, and fire exclusion. In 2009, the U.S. Forest Service began to install permanent plots in whitebark pine stands in Washington and Oregon as …

Is Chimpanzee (Pan Troglodytes) Wounding Frequency Affected By The Presence Versus Absence Of Visitors? A Multi-Institutional Study, Robin Elana Salak, Christina Cloutier Barbour

Student Published Works

Visitor effect studies have had inconsistent results, due in part to the inability to control for all confounding variables such as time of day, seasonal weather patterns, and so forth. This study represents the first instance where chimpanzee (Pan troglodytes) wounding frequencies were investigated across extensive time periods in the presence and complete absence of visitors, thus eliminating many visitor-related variables. Additional variables were eliminated through the zoo selection process, based on institutional responses to a 29-question survey, providing a novel approach to the question of visitor effects. The aim of this study was to determine if visitors …

Ants And Spices: Multiple Bioassays Investigating Turmeric (Curcuma Longa) And Chili Powder As Repellents For Ants (Formicidae), Luca Ben Yishay-Sapalio

2022 REYES Proceedings

Spices offer an environmentally friendly method of controlling ants (Formicidae) in homes. In this study, I used three bioassays to examine the effect of Turmeric (Curcuma longa) and one bioassay to examine the effect of Chili Powder as repellents for ants. Tests were conducted near active ants outdoors. All bioassays examined paired control and treatment baits along a transect, and control baits consisted of a small sheet of corrugated cardboard (a sterile yet easy to manipulate substrate) with granulated sugar on top. In the first bioassay, treatment baits were similar to controls but with Turmeric covering the sugar. …

Evaluation Of Silver Nanoparticles Attached To Methylene Blue As An Antimicrobial Agent And Its Cytotoxicity, Somon Hakimov

Masters Theses & Specialist Projects

Antibiotics resistance is considered as one of the greatest public health challenges of our time. In this work, we have synthesized silver nanoparticles (Ag NPs) using pulsed liquid ablation in different medium of growth and later combined with methylene blue (MB) to evaluate its potential as an effective photodynamic therapy agent. Ag NPs were synthesized by pulsed laser ablation technique in Polyvinylpyrrolidone (PVP), citrate, and Polyvinyl alcohol (PVA). The Ag NPs were characterized using transmission electron microscopy (TEM), UV-Visible (UV-Vis), and photoluminescence (PL) spectra. Next, Ag NPs were coupled with MB and used to deactivate the Gram-negative bacteria, Escherichia coli …

Total Prevention: A History Of Schistosomiasis In Japan, Alexander Bay

History Faculty Articles and Research

In Japan, schistosomiasis was endemic in Yamanashi Prefecture and a few other hotspot areas where the Miya’iri snail lived. The parasite’s lifecycle relied on the intermediary Miya’iri snail as well as the human host. Parasite eggs passed into the agrarian environment through untreated night soil used as fertiliser or through the culture of open defecation in rural Japan. Manmade rice fields and irrigation ditches, night soil covered paddies and highly refined growing seasons put people in flooded rice paddies to intensively work the land in the spring and summer. The disease was equally dependent on human intervention in the natural …
