Offspring Production With Cryopreserved Sperm From A Live-Bearing Fish Xiphophorus Maculatus And Implications For Female Fecundity, Huiping Yang, Markita G. Savage, Leona Hazlewood, Ronald B. Walter, Terrence R. Tiersch

Faculty Publications

Xiphophorus fishes are well-established models for biomedical research of spontaneous or induced tumors, and their use in research dates back to the 1930s. Currently, 58 well-pedigreed lines exist among 24 Xiphophorus species housed as live animals at the Xiphophorus Genetic Stock Center. The technique of sperm cryopreservation has been applied to preserve these valuable genetic resources, and production of offspring has been reported with cryopreserved sperm in two species (X. helleri and X. couchianus). The goal of this research was to establish protocols for sperm cryopreservation and artificial insemination that yield live young in X. maculatus, a widely used research …

Host Interferon-Γ Inducible Protein Contributes To Brucella Survival., Jennifer A. Ritchie, Adam Rupper, James A. Cardelli, Bryan H. Bellaire

Faculty Publications

Brucella spp. are highly adapted intracellular pathogens of mammals that cause chronic infections while surving and replicating in host monocytes and macrophages. Although monocytes are normally susceptible to infection, pretreatment with pro-inflammatory cytokine interferon-γ (IFN-γ) activates cellular defense mechanisms that increase intracellular killing of Brucella and prevents bacterial replication. We examined the contribution of the IFN-γ inducible GTPase, LRG-47, to B. abortus 2308 infection in in vitro and in vivo murine models. Infecting non-activated macrophages from LRG-47(-/-) mice revealed that loss of this host protein negatively effected the intracellular survival and replication of IgG opsonized B. abortus. In contrast, survival …

The Origin And In Situ Identification Of Uncultured Gut Bacteria In Fourth-Instar Larvae Of The Red Imported Fire Ant, Solenopsis Invicta (Hymenoptera: Formicidae), Albert H. Lee, Linda Hooper-Bui

Faculty Publications

This study corroborated the findings of Lee et al. (2008) and relied on culture-independent techniques, particularly 16SrDNA sequencing. Results from the study demonstrated that ants in captivity completely change their gut bacterial diversity strongly supports the conclusion that fire ant gut bacteria are environmental in origin. Bacteria in the fourth-instar larvae were present because they were consumed with food sources. From molecular data, a differing list of bacteria from each colony with different branching and clustering among bacterial clades in the phylogenetic trees were found. Different bacterial diversity and evenness was found in all colonies, which provided evidence against the …

Integrated Management Of The Red Imported Fire Ant In Pastures, William Sullivan Hilbun

LSU Master's Theses

The effects and interactions of chemical, cultural, and biological control of red imported fire ant (RIFA) populations were evaluated in two replicated studies in pastures. The first study was conducted from 2005 through 2007 in Washington parish, Louisiana (WP) where the biological control Psuedacteon tricupsis phorid flies were present and at the LSU AgCenter St. Gabriel Research Station in St. Gabriel, Louisiana (SG) where Psuedacteon tricuspis flies were absent. The second study was conducted from May 2009 to May 2010 at St. Gabriel in the presence of phorid flies. In both studies, RIFA population indices in sites treated with methoprene …

Role Of Intraocular Leptospira Infections In The Pathogenesis Of Equine Recurrent Uveitis In The Southern United States, Florence Polle

LSU Master's Theses

To investigate the role of intraocular leptospiral infections in horses with Equine Recurrent Uveitis (ERU), ocular fluid samples were collected from donated and client-owned horses with a history and ocular findings consistent with chronic ERU. Additionally, eyes were harvested from horses with normal ophthalmic examinations as a control group. Blood samples were obtained for Leptospira serology using microscopic agglutination test (MAT). Aqueous and vitreous humor samples were aseptically obtained and submitted for aerobic culture and Leptospira culture, PCR and MAT. Twenty-one control horses (40 eyes) and 31 ERU horses (46 eyes) were available for study. Serology results were available for …

Characterization Of The Promoter And Insulator Activities Of The Scs' Insulator, Yu Ge

LSU Master's Theses

Eukaryotic gene expression is regulated by regulatory elements. Insulators are one class of regulatory sequences. They can prevent heterochromatin from spreading into euchromatin, block distal enhancer activity, or both. Insulators function by recruiting several associated proteins. The scs’ insulator, which is located at one end of the 87A7 hsp 70 locus, is bound by BEAF. In the Drosophila genome, more than 85 % of BEAF binding sites are found within 300 bp of transcription start sites, suggesting BEAF may be involved in promoter function. Based on previous insulator position effect assays, two sequences were found to be necessary for full …

Up Like Weeds, Danielle Burns

LSU Master's Theses

A child playing with matches is forgivable. Kids are curious. They want to explore adult activities through play. Does it stay innocent when that child experiments with the effects of firecrackers in frogs and gasoline on animals? What happens when they light the match? The grey area between childhood innocence and realization of wrong intrigues me and I find it fascinating how adult perspectives of such malicious deeds often vary. Up Like Weeds questions these responses using a collection of narrative prints and freestanding woodcut figures. They visually tell five tales of children in a rural environment acting out in …

Designing Pots: Determining Orange Incised Design Variation And Distribution At The Rollins Shell Ring Site And The Guana Shell Ring Site In Florida, Margaret Kathryn Wrenn

LSU Master's Theses

Orange pottery is a Late Archaic (5000-3000 B.P.) fiber-tempered pottery found throughout northern and central Florida, though the heartland of the ware is considered to be in the northeastern part of Florida. Orange pottery is most commonly plain, but incised Orange pottery is frequently found at shell ring sites on the eastern Florida coast. Prior examinations of Orange Incised pottery have indicated design considerable homogeneity in design at Orange Period sites. The highest percentage of decorated pottery is found at shell ring sites. For this thesis, I conducted an analysis and comparison of Orange Incised pottery collections from two contemporaneous …

Development Of A Frozen Yogurt Fortified With A Nano-Emulsion Containing Purple Rice Bran Oil, Luis Alonso Alfaro Sanabria

LSU Master's Theses

The U.S. frozen dessert business, including retail and foodservice markets, is the largest in the world. There is a need for deserts that offer better nutritional attributes, such as antioxidants than traditional deserts. Purple rice bran oil (PRBO) is an excellent source of natural antioxidants including tocopherol, tocotrienol, and oryzanol. Adding nano-emulsions of purple rice bran oil (NPRBO) to many products including frozen yogurts (FY) will improve the nutritional profile of the product by substantially increasing the natural antioxidant content. This fortification may have the potential to broaden the FY market. The objectives of this study were to develop and …

LSU Master's Theses

North to South is a series of photographs that reflect ideas of home and community. The images and video components depict portraits of my neighbors taken over the last two years. The individuals I photographed were crucial to my process, for with their help and a simple homemade photo booth, I found a “home” here in the south.

The Ecological Impact Of The Deepwater Horizon Oil Spill On Vibrio Parahaemolyticus Type Iii Secretion System And The Vibrio Community, Erica L. Stephens

LSU Master's Theses

Vibrio spp are gram-negative, halophilic bacteria that naturally occur in both shallow coastal waters and parts of the deepest oceans and are a known human pathogen. There have not been extensive studies that analyze an oil spill as an environmental stressor to vibrios. If there were to be an increase in the pathogenicity of vibrios it would be a cause for human health concern. The purpose of the two studies presented was to determine changes in the pathogenicity of V. parahaemolyticus pathogenicity and the vibrio community, with respect to V. cholera, V. parahaemolyticus, and V. vulnificus. The results showed that …

Partnership Representation In Public Communications: An Analysis Of Community-Engaged Universities' Websites, Christy Kayser Arrazattee

LSU Master's Theses

This study examines the ways in which campus-community partnerships are represented in public communications produced by community-engaged institutions of higher education. Leading scholars of campus-community partnerships and service-learning agree that such relationships should be based on a reciprocal exchange between partners. In public relations endeavors, however, professionals concentrating solely on communicating the university’s achievements may overlook the equal contributions of the community partner. This study analyzed website content and universities publications from six colleges nationally recognized for their community-engagement efforts. Using quantitative and qualitative analysis, web content was analyzed for indicators of reciprocity developed from foundational literature regarding campus-community partnerships. …

Evaluation Of Phosphorous And Nitrogen Removal In Alligator And Dairy Wastewater Via Lime And Bentonite Precipitation, Srikanth Bukkapatnam Tirumala

LSU Master's Theses

In many situations, the manure produced by confined animal feeding operations (CAFO) needs to be treated before being land applied in order to prevent negative impacts on the environment. Treatment methods are focused on reducing organics, recovering nitrogen and phosphorous. The purpose of this study is to evaluate the efficacy of burnt-lime (Ca(OH)2) and bentonite clay precipitation system of recovering phosphorous from dairy wastewater and alligator wastewater and trapping any possible emissions of ammonia (NH3). Wastewater samples of flush dairy manure from a collection pit, dairy wastewater from an anaerobic lagoon and alligator wastewater from an anaerobic lagoon were investigated …

Repeatability Of Prolactin Responses To Sulpiride In Mares And Geldings And The Effect Of Pergolide And Cabergoline, Rebekah C. Hebert

LSU Master's Theses

Four experiments were conducted in an effort to develop a method, based on prolactin secretion, for assessing the efficacy and duration of activity of dopaminergic agonists for the treatment of pituitary pars intermedia dysfunction (PPID) in horses. In the first experiment, prolactin response to a low dose of the dopamine antagonist, sulpiride, was generally repeatable in estrogen-primed geldings in winter over 8 every-other-day challenges. It was concluded that estrogen-primed, sulpiride-challenged geldings in winter could serve as a model for the study of potential dopaminergic drugs for the treatment of PPID in horses. The second experiment was performed in the summer …

Impact Of Teaching Style On Student Learning Of Evolution, Laurie Font

LSU Master's Theses

Natural selection is a topic that is laden with misconceptions. These misconceptions are often not addressed, and students can leave a biology classroom with the same incorrect ideas that they entered with. These misconceptions can be identified and addressed by using the Concept Inventory of Natural Selection (CINS). Furthermore, by teaching using methods that encourage hands-on, inquiry based techniques, students are more apt to reconcile these misconceptions and have a deeper understanding of the natural selection process. The goal of my research was to show a positive correlation between reduction in student misconceptions about natural selection and inquiry based activities. …

Evaluating The Efficacy Of Methoxyfenozide On Louisiana, Texas And The Mid-Southern Soybean Looper Populations, Sebe Anthony Brown

LSU Master's Theses

The soybean looper, Chrysodeixis includens (Walker), is a defoliating insect pest of soybean in the Mid-South and Texas. In 2008, Louisiana producers reported unsatisfactory control of soybean loopers in soybean with methoxyfenozide. In 2009 and 2010, field collections from Louisiana, Missouri, Mississippi and Texas were exposed to discriminating concentrations (0.020 to 5.000 ai ìg/ml) of methoxyfenozide in diet incorporation bioassays. All field colonies were compared to a reference strain LC50 of 0.007 ìg/ml for 2009 and 0.008 ìg/ml for 2010. Louisiana populations exhibited LC50’s of 0.079 ìg/ml and 0.122 ìg/ml for 2009 and 2010, respectively, which were the highest values …

Lentiviral Transduction Of Epigenetically Modified Bovine Adult Stem Cells, Meredith Kathleen Addison

LSU Master's Theses

Bovine adipose-derived stem cells (ADS), a form of adult stem cells, are somatic cells that have similar characteristics of embryonic stem (ES) cells. Bovine ADS cells possess multipotent capabilities and have been found to express pluripotency genes associated with ES cells. The unique properties of ADS cells make them a desirable source for reprogramming experiments. The goal of reprogramming experiments is to transform somatic cells from a differentiated state to a pluripotent state. When somatic cells reprogram, there are certain epigenetic changes or modifications that must occur in order to successfully reprogram the nucleus. Epigenetic modifications will change the chromatin …

Evaluation Of Single Nucleotide Polymorphisms Associated With Fertility And Production Traits In Holstein And Multi-Generational Angus Females, Rebecca Ann Hill

LSU Master's Theses

The objective of this study was to test the association of single nucleotide polymorphisms (SNPs) with fertility in two populations consisting of Holstein cows and multi-generational Angus cows. The candidate gene approach was utilized and previously described SNPs were tested for possible associations with fertility. Single nucleotide polymorphisms on three genes were evaluated including leptin receptor LEPR, calpastatin CAST, and DGAT1. Fertility traits were evaluated in conjunction with production traits for Holstein females and growth traits for Angus females. One SNP was significantly associated with birth weight (P < 0.05) in Angus females while a trend (P < 0.10) was observed for two markers influencing birth weight performance and three markers influencing weaning weight performance. An association of two SNP for birth weight and back fat thickness in Angus females was identified.!A trend (P < 0.10) was observed for one marker within LEPR influencing average services to conception, two markers within CAST influencing average days open, two markers within CAST and one marker within DGAT1 influencing average protein production, and one marker within CAST and one marker within DGAT1 influencing average milk production. One SNP within LEPR was significantly associated with average milk production (P < 0.05) in Holstein females. An association of one SNP within CAST and one SNP within DGAT1 for average protein production and average milk production in Holstein females was identified. An association of one SNP within CAST for average days open and average protein production in Holstein females was also identified. The association of these markers indicates that the evaluated quantitative trait loci (QTL) region may harbor causative mutations responsible for the variation observed in fertility and production traits. Further evaluation of SNP in these regions is necessary in order to identify mutations accounting for the largest degree of variation for fertility and production traits.

Understanding Public Perceptions Of Global Warming, Wanyun Shao

LSU Doctoral Dissertations

In this dissertation, I investigate the determinants on Americans’ perceptions of global warming and individuals’ environmentally significant behaviors to reduce global warming. Specially, I examine how contextual variables, primarily represented by local weather and climate, attitudinal variables, and socio-demographic characteristics affect public opinion towards global warming, personal voluntary actions and willingness to address global warming. The research of this dissertation reveals some important findings. First, local weather and climate—represented by long-term temperature trends—is found to have significant effects on public perceptions of global warming and private-sector environmentally significant behaviors. In particular, the summer temperature trend over the past 10 years …
