Aerobic Fitness Is Of Greater Importance Than Strength And Power In The Load Carriage Performance Of Specialist Police, Jeremy Robinson, Adam Roberts, Shane Irving, Robin M. Orr

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 987-998, 2018.Police officers are required to carry external loads as part of their occupation. One means of preparing officers to carry loads is through physical conditioning. The aim of this study was to investigate whether strength, power or aerobic endurance had the greatest association with load carriage performance. Retrospective data from 42 male specialist tactical police officers (mean body weight = 88.8±8.25 kg) informed this study. Baseline data were provided for strength (1 Repetition Maximum [RM] bench press, deadlift, squat and pull-up), lower body power (vertical jump, 10m sprint) and aerobic (‘beep’ test) …

The Role Of Nucleophosmin And Neurotoxic Dipeptide Repeat Proteins In Amyotrophic Lateral Sclerosis, Nadja Soares De Andrade

Open Access Dissertations

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with an incidence of 15 new cases per day in the United States alone. To date there is no cure, only a modestly effective treatment to extend life by only a few months. A repeat expansion mutation within the C9ORF72 (chromosome 9 open reading frame 72) gene is the most common known cause of both sporadic and familial cases of ALS and frontotemporal dementia, a related neurodegenerative disease. Despite the identification of the C9ORF72 expansion mutation, the mechanism by which it confers neurotoxicity remains unknown. C9ORF72 expansion mutation produces toxic dipeptide …

Microglial Inflammasome Activation In Penetrating Traumatic Brain Injury, Stephanie Wen-Ting Lee

Open Access Dissertations

Inflammasomes are one of the key regulators of interleukin (IL)-1β mediated inflammatory responses after traumatic brain injury. However, the role of inflammasome signaling after penetrating traumatic brain injury (PTBI) has not been determined. Towards this, adult male Sprague-Dawley rats were subjected to sham or penetrating ballistic-like brain injury (PBBI) surgery and sacrificed at various time points. Tissues were assessed by immunoblot analysis for expression of IL-1β, IL-18 and components of the inflammasome: caspase-1, apoptosis-associated speck like protein containing a caspase activation and recruitment domain (ASC), X-linked inhibitor of apoptosis protein (XIAP), NOD-like receptor protein 3 (NLRP3), and gasdermin-D (GSDMD). Specific …

Increasing Water Use Efficiency By Nitrogen Management In Turfgrass, Austin Hopkins, Dr. Neil C. Hansen

Journal of Undergraduate Research

This project identifies turfgrass practices to conserve water by optimizing nitrogen (N) fertilization and irrigation strategies. Turfgrass is the most irrigated crop by area (163,800 km2), accounting for 1.9% of the continental U.S. This causes negative environmental impacts and puts the future of irrigated turfgrass in question due to increasing water scarcity, especially in the western U.S. More information is needed on how to irrigate in droughts as turf provides significant benefits in our environment such as aesthetics, cooling effects, carbon sequestration, and preventing soil erosion.

Structure Of The Mouse Trpc4 Ion Channel, Jingjing Duan, Jian Li, Bo Zeng, Gui-Lan Chen, Xiaogang Peng, Yixing Zhang, Jianbin Wang, David E. Clapham, Zongli Li, Jin Zhang

Molecular and Cellular Biochemistry Faculty Publications

Members of the transient receptor potential (TRP) ion channels conduct cations into cells. They mediate functions ranging from neuronally mediated hot and cold sensation to intracellular organellar and primary ciliary signaling. Here we report a cryo-electron microscopy (cryo-EM) structure of TRPC4 in its unliganded (apo) state to an overall resolution of 3.3 Å. The structure reveals a unique architecture with a long pore loop stabilized by a disulfide bond. Beyond the shared tetrameric six-transmembrane fold, the TRPC4 structure deviates from other TRP channels with a unique cytosolic domain. This unique cytosolic N-terminal domain forms extensive aromatic contacts with the TRP …

Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly

HCNSO Student Theses and Dissertations

South Florida contains one of the largest subtropical wetlands in the world, and yet not much is known about the microbes that live in these surface waters. These microbes play an important role in chemical cycling and maintaining good water quality for both human and ecosystem health. The hydrology of Florida’s surface waters is tightly regulated with the use of canal and levee systems run by the US Army Corps of Engineers and The South Florida Water Management District. These canals run through the Everglades, agriculture, and urban environments to control water levels in Lake Okeechobee, the Water Conservation Areas, …

Node-Based Resilience Measure Clustering With Applications To Noisy And Overlapping Communities In Complex Networks, John Matta, Tayo Obafemi-Ajayi, Jeffrey Borwey, Koushik Sinha, Donald Wunsch, Gunes Ercal

College of Natural and Applied Sciences

This paper examines a schema for graph-theoretic clustering using node-based resilience measures. Node-based resilience measures optimize an objective based on a critical set of nodes whose removal causes some severity of disconnection in the network. Beyond presenting a general framework for the usage of node based resilience measures for variations of clustering problems, we experimentally validate the usefulness of such methods in accomplishing the following: (i) clustering a graph in one step without knowing the number of clusters a priori; (ii) removing noise from noisy data; and (iii) detecting overlapping communities. We demonstrate that this clustering schema can be applied …

A-Type Kv Channels In Dorsal Root Ganglion Neurons: Diversity, Function, And Dysfunction, Benjamin M. Zemel, David M. Ritter, Manuel Covarrubias, Tanziyah Muqeem

Department of Neuroscience Faculty Papers

A-type voltage-gated potassium (Kv) channels are major regulators of neuronal excitability that have been mainly characterized in the central nervous system. By contrast, there is a paucity of knowledge about the molecular physiology of these Kv channels in the peripheral nervous system, including highly specialized and heterogenous dorsal root ganglion (DRG) neurons. Although all A-type Kv channels display pore-forming subunits with similar structural properties and fast inactivation, their voltage-, and time-dependent properties and modulation are significantly different. These differences ultimately determine distinct physiological roles of diverse A-type Kv channels, and how their dysfunction might contribute to neurological disorders. The importance …

Natural And Managed Watersheds Show Similar Responses To Recent Climate Change, Darren L. Ficklin, John T. Abatzoglou, Scott M. Robeson, Sarah E. Null, Jason H. Knouft

Watershed Sciences Faculty Publications

Changes in climate are driving an intensification of the hydrologic cycle and leading to alterations of natural streamflow regimes. Human disturbances such as dams, land-cover change, and water diversions are thought to obscure climate signals in hydrologic systems. As a result, most studies of changing hydroclimatic conditions are limited to areas with natural streamflow. Here, we compare trends in observed streamflow from natural and human-modified watersheds in the United States and Canada for the 1981–2015 water years to evaluate whether comparable responses to climate change are present in both systems. We find that patterns and magnitudes of trends in median …

An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi

Theses and Dissertations

The investigator attempted to predict the vocal learning propensity from either family pedigree or early vocal babbling (subsong). Pedigree trees suggest the possibility that vocal learning ability may depend on family. We failed to predict vocal learning propensity from subsong, but suggested that subsong may influence vocal learning outcome.

Green Tea Polyphenol Epigallocatechin-3-Gallate-Stearate Inhibits The Growth Of Streptococcus Mutans: A Promising New Approach In Caries Prevention, Amy Lynn Melok, Lee Lee, Siti Ayuni Mohamed Yussof, Tinchun Chu

Department of Biology Faculty Scholarship and Creative Works

Streptococcus mutans (S. mutans) is the main etiological bacteria present in the oral cavity that leads to dental caries. All of the S. mutans in the oral cavity form biofilms that adhere to the surfaces of teeth. Dental caries are infections facilitated by the development of biofilm. An esterified derivative of epigallocatechin-3-gallate (EGCG), epigallocatechin-3-gallate-stearate (EGCG-S), was used in this study to assess its ability to inhibit the growth and biofilm formation of S. mutans. The effect of EGCG-S on bacterial growth was evaluated with colony forming units (CFU) and log reduction; biofilm formation was qualitatively determined by Congo red assay, …

The three participants were employed as assistant professors in CACREP-accredited counselor education graduate programs provided their perspectives of research mentorship. The primary research question for my research was: How do pre-tenured African American female counselor educators perceive their research mentorship experiences? The foundation for my study was provided by the review of literature focused on critical race theory, marginalized groups in academe, mentorship among …

Hydrodynamics Of An Anguilliform Swimming Motion Using Morison’S Equation, Naga Sasi Devarakonda

LSU New Orleans Theses and Dissertations

In this study, the hydrodynamic performance of anguilliform swimming motion is computed using Morison’s equation. This method was shown to predict the servo motor torques well. The anguilliform swimming motion is sinusoidal with increasing amplitude from head to tail. A “wakeless” swimming motion proposed by Vorus and Taravella (2011) with zero net circulation is considered.

This method is compared to the existing slender body theory and is validated with reference to the experimental results of NEELBOT-1.1 (Potts, 2015). The results for the study indicates that self-propulsion speed of the motion is independent of the oscillating tail amplitude at a constant …

Effect Of Torpor On Host Transcriptomic Responses To A Fungal Pathogen In Hibernating Bats, Kenneth A. Field, Brent J. Sewall, Jenni M. Prokkola, Gregory G. Turner, Marianne Gagnon, Thomas M. Lilley, J Paul White, Joseph S. Johnson, Christopher L. Hauer, Deeann M. Reeder

Faculty Journal Articles

Hibernation, the use of prolonged torpor to depress metabolism, is employed by mammals to conserve resources during extended periods of extreme temperatures and/or resource limitation. Mammalian hibernators arouse to euthermy periodically during torpor for reasons that are not well understood and these arousals may facilitate immune processes. To determine if arousals enable host responses to pathogens, we used dual RNA‐Seq and a paired sampling approach to examine gene expression in a hibernating bat, the little brown myotis (Myotis lucifugus). During torpor, transcript levels differed in only a few genes between uninfected wing tissue and adjacent tissue infected with …

Parental Stress, Anxiety, And Depression And Child Emotional Intelligence In Children With 22q11.2 Deletion Syndrome, Megan A. Goldfarb

LSU New Orleans Theses and Dissertations

Children with chromosome 22q11.2 deletion syndrome (22q11.2DS) have serious medical, psychological, and behavioral symptoms that are stressful to their parents. Higher general intelligence quotients (IQ) and emotional intelligence (EI) in children could allay parental stress. Self-reported stress, anxiety, and depression were measured in parents of children with 22q11.2DS (n=42) and a healthy control group (n=20) in relation to children’s IQ and EI. Children with 22q1.2DS had lower IQ and EI scores. Parental groups did not differ in their reported stress, anxiety, or depression. Children’s IQ and EI levels did not relate to parental measures of affect even in the 22q11.2DS …

Analysis Of Temperature And Salinity Effects On Growth And Mortality Of Oysters (Crassostrea Virginica) In Louisiana, Troy Sehlinger

LSU New Orleans Theses and Dissertations

Salinity (S) and temperature (T) control every facet of the eastern oyster (Crassostrea virginica) life cycle, principally reproduction, development, growth, and mortality. Previous studies conducted in in the Breton Sound (BR) and Barataria (BA) estuaries have reported differences in growth and mortality rates between the basins. In the present study, environmental conditions were synchronized to compare growth and mortality rates between basins at similar combinations of T and S. Results indicate that when T and S are the same (synchronized), seasonal oyster growth and mortality rates differ between BR and BA. Seasonal analyses revealed that as salinities increased …

A Longitudinal Examination Of The Association Between Contextual Stress, Parenting, And School Readiness, Jessica M. Grande

LSU New Orleans Theses and Dissertations

Contextual stress has been associated with poor school readiness skills during early childhood. This study evaluated mechanisms by which parent’s exposure to poverty-related contextual stressors influence the acquisition of school readiness skills from child age 2 to 4 among 167 parent-child dyads. Parent report of contextual stress and observational measures of parenting quality were collected during the children’s 2-year-old assessment. Teacher reports and children’s scores on school readiness tasks were collected during the 4-year-old assessment. Two approaches were used to understand the process by which contextual stressors influences school readiness; the accumulation of stressors approach and the constellations of stressors …

Manana: A Generalized Heuristic Scoring Approach For Concept Map Analysis As Applied To Cybersecurity Education, Sharon Elizabeth Blake Gatto

LSU New Orleans Theses and Dissertations

Concept Maps (CMs) are considered a well-known pedagogy technique in creating curriculum, educating, teaching, and learning. Determining comprehension of concepts result from comparisons of candidate CMs against a master CM, and evaluate "goodness". Past techniques for comparing CMs have revolved around the creation of a subjective rubric. We propose a novel CM scoring scheme called MAnanA based on a Fuzzy Similarity Scaling (FSS) score to vastly remove the subjectivity of the rubrics in the process of grading a CM. We evaluate our framework against a predefined rubric and test it with CM data collected from the Introduction to …

Zooplankton Community Composition In Natural And Artificial Estuarine Passes Of Lake Pontchartrain, Louisiana, Arnaud Kerisit

I assessed the composition of zooplankton communities at the three tidal inlets connecting Lake Pontchartrain to Lake Borgne and subsequently to the Gulf of Mexico. The objectives of my research were to better understand the factors contributing to both spatial and temporal differences in zooplankton communities at the three locations. Monthly samplings of the neuston were conducted from September 2009 until April 2011 and then again from September 2012 until May 2013. Sampling consisted of triplicate tows using SeaGear “Bongo” nets. Water quality data along with water turbidity were recorded at each site and during each sampling effort. All specimens …

The Bidirectional Relationship Between Obstructive Sleep Apnea And Metabolic Disease, Sarah N. Framnes, Deanna M. Arble

Biological Sciences Faculty Research and Publications

Obstructive sleep apnea (OSA) is a common sleep disorder, effecting 17% of the total population and 40–70% of the obese population (1, 2). Multiple studies have identified OSA as a critical risk factor for the development of obesity, diabetes, and cardiovascular diseases (3–5). Moreover, emerging evidence indicates that metabolic disorders can exacerbate OSA, creating a bidirectional relationship between OSA and metabolic physiology. In this review, we explore the relationship between glycemic control, insulin, and leptin as both contributing factors and products of OSA. We conclude that while insulin and leptin action may contribute …

Laboratory Growth Of Denitrifying Water Column Microbia Consortia From Deep-Sea Shipwrecks In The Northern Gulf Of Mexico, Dhanya Haridas, Justin C. Biffinger, Thomas J. Boyd, Preston A. Fulmer, Leila J. Hamdan, Lisa A. Fitzgerald

Faculty Publications

Background: Shipwrecks serve as a rich source for novel microbial populations that have largely remained undiscovered. Low temperatures, lack of sunlight, and the availability of substrates derived from the shipwreck’s hull and cargo may provide an environment in which microbes can develop unique metabolic adaptations.

Methods: To test our hypothesis that shipwrecks could influence the microbial population involved in denitrification when a consortium is grown in the laboratory, we collected samples proximate to two steel shipwrecks in the northern Gulf of Mexico. Then under laboratory conditions, we grew two independent denitrifying microbial consortia. Each consortium was grown by …

Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer

Entomology Faculty Publications

Elemental data are commonly used to infer plant quality as a resource to herbivores. However, the ubiquity of carbon in biomolecules, the presence of nitrogen-containing plant defensive compounds, and variation in species-specific correlations between nitrogen and plant protein content all limit the accuracy of these inferences. Additionally, research focused on plant and/or herbivore physiology require a level of accuracy that is not achieved using generalized correlations. The methods presented here offer researchers a clear and rapid protocol for directly measuring plant soluble proteins and digestible carbohydrates, the two plant macronutrients most closely tied to animal physiological performance. The protocols combine …

The Guanylate Cyclase C-Cgmp Signaling Axis Opposes Intestinal Epithelial Injury And Neoplasia., Jeffrey A. Rappaport, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Guanylate cyclase C (GUCY2C) is a transmembrane receptor expressed on the luminal aspect of the intestinal epithelium. Its ligands include bacterial heat-stable enterotoxins responsible for traveler's diarrhea, the endogenous peptide hormones uroguanylin and guanylin, and the synthetic agents, linaclotide, plecanatide, and dolcanatide. Ligand-activated GUCY2C catalyzes the synthesis of intracellular cyclic GMP (cGMP), initiating signaling cascades underlying homeostasis of the intestinal epithelium. Mouse models of GUCY2C ablation, and recently, human populations harboring GUCY2C mutations, have revealed the diverse contributions of this signaling axis to epithelial health, including regulating fluid secretion, microbiome composition, intestinal barrier integrity, epithelial renewal, cell cycle progression, responses …

Conservation Applications Of Watershed-Level Brook Trout Riverscape Genetics, Lucas Nathan

Doctoral Dissertations

Contemporary Brook Trout Salvelinus fontinalis populations are often fragmented due to anthropogenic influences. Although research and conservation actions have traditionally focused at the stream-reach level, inter-stream movements may connect seemingly isolated populations to form larger metapopulations. The overall goal of my research was to use watershed-level riverscape genetics to inform Brook Trout conservation. Specifically, my objectives were to 1) present a synthesis of existing Brook Trout literature and identify future research directions, 2) evaluate Brook Trout genetic population structuring and identify gene flow barriers at the watershed level, 3) validate and modify a pre-existing Brook Trout habitat patch spatial layer …
