Optimization Of The Extraction Of Procyanidin B-2 Rich Extract From Unfermented Cocoa Using Response Surface Methodology And Interaction Of Procyanidin B-2 Rich Cocoa Extract With Collagenase And Elastase As Biomarkers Of Skin Aging, Marco Eduardo Toc Sagra
LSU Master's Theses
Skin ageing is a natural process accelerated by environmental exposure that generate reactive oxygen species and activates enzymes that degrade the integrity of the dermis. Cocoa powder (Theobroma cacao) is a good source of polyphenols, particularly procyanidins and flavan-3-ols, with potential enzyme inhibitory activities. In this study we determined whether cocoa extraction standardized to its procyanidin B-2 content has a potential application as anti-ageing bioactive compound. Oil-bath-assisted extraction (OBAE) and microwave-assisted extraction (MAE) were optimized for procyanidin B-2 rich extract using response surface methodology and water as solvent. Methanol (70% in water) extraction was the control to which other extraction …
Evaluation Of Estrous Response Patches As A Tool To Determine Optimum Timing For Artificial Insemination And If Gonadotropin-Releasing Hormone Is Needed At Timed-Ai In Beef Cattle, Danilo Demeterco
LSU Master's Theses
Two experiments evaluated using an estrous-detection patch to identify animals that are in standing estrus at split-timed AI (STAI) and the necessity of a gonadotropin-releasing hormone (GnRH) injection at STAI on a 7-Day CO-Synch + CIDR protocol. In experiment 1 (n=216) and in experiment 2 (n=101), multiparous lactating crossbred beef cows were stratified by age, BW, BCS, and post-partum interval to 2 treatment groups: CTRL=timed-AI (TAI) at 72h post CIDR removal, or TRT=STAI at 72 or 84h post CIDR removal. All females received GnRH plus a CIDR on d0, prostaglandin-F2α, CIDR removal, and an Estrotect estrous-detector patch on d7. At …

Effects Of Timing Of Local Anesthesia On Physiological Responses In Calves After Dehorning, Amanda Jane Mathias
LSU Master's Theses
The American Veterinary Medical Association has stated the importance of minimizing pain associated with dehorning to limit the amount of distress and changes in the animal’s behavior and physiological states (AVMA, 2014b). The following studies aim to determine the effect of timing of lidocaine administration on physiological responses in calves after dehorning. The first study compared cortisol and substance P levels in calves dehorned immediately after administration of lidocaine and meloxicam, calves dehorned 10 minutes after the administration of lidocaine and meloxicam, and calves that were administered lidocaine and meloxicam and not dehorned. It was concluded waiting 10 minutes after …
Lignocellulosic Syrup Production From Energy Cane Bagasse And Fumaric Acid Fermentation, Fang Deng
Lignocellulosic Syrup Production From Energy Cane Bagasse And Fumaric Acid Fermentation, Fang Deng
LSU Doctoral Dissertations
Lignocellulosic syrup from dilute ammonia pretreated energy cane bagasse is a promising fermentable sugar feedstock that can improve the logistics associated with long-distance transportation, long-time storage, and year-round supply of lignocellulosic biomass to processing industries. However, non-sugar compounds such as organic acids, furans and phenolic compounds formed during pretreatment can have negative effects on downstream processes such as fermentation. This dissertation focused on addressing challenges associated with the bioconversion of energy cane bagasse to syrup and its fermentation to fumaric acid. The first goal (Chapter 2) was to evaluate the removal of non-sugar compounds with minimal sugar losses from dilute …
Termite Gut Microbes As Tools And Targets For Termite Control, Chinmay Vijay Tikhe
Termite Gut Microbes As Tools And Targets For Termite Control, Chinmay Vijay Tikhe
LSU Doctoral Dissertations
The Formosan subterranean termite (FST), Coptotermes formosanus, is an invasive urban pest in the United States. Colonies of the FST are dependent on the symbiotic gut protozoa for cellulose digestion in the workers’ guts, and the gut bacterial community is known to provide essential nutrients to the termite. The objectives of this PhD research were to develop and evaluate paratransgenesis and phage therapy for termite control. During this study, a termite gut bacterium: Trabulsiella odontotermitis was genetically engineered and was evaluated as a ‘Trojan horse’ for paratransgenesis. We proved that T. odontotermitis can tolerate 50 times more concentration of ligand-Hecate …
Cold Tolerance And Overwintering Physiology Of The Salvinia Weevil (Cyrtobagous Salviniae): Improving The Biological Control Of Giant Salvinia In Temperate Louisiana, Alana D. Russell
LSU Master's Theses
Cyrtobagous salviniae is widely used for biological control of Salvinia molesta. Despite success in tropical and subtropical regions, the effectiveness of C. salviniae on S. molesta is inconsistent in temperate regions, indicating the need for a better understanding of the thermal biology of this agent. The objectives of this study were to compare cold tolerance of C. salviniae populations from the temperate native range and Louisiana, and characterize the overwintering physiology and population dynamics of C. salviniae in Louisiana. Surveys of the Lower Paraná-Uruguay Delta resulted in the first record of C. salviniae in Uruguay, and revealed the most southern …

Molecular Genetics Of Cold Tolerance At Germination And Seedling Stages In Rice, Anna Hissahe Borjas Artica
Molecular Genetics Of Cold Tolerance At Germination And Seedling Stages In Rice, Anna Hissahe Borjas Artica
LSU Master's Theses
Low temperature stress is a major constraint for rice production in temperate and high altitude areas of the world. Delayed germination coupled with reduced seedling vigor hinders crop establishment and crop growth resulting in reduced rice productivity. Mapping of chromosomal regions controlling cold tolerance will accelerate marker-assisted breeding of cold tolerant rice varieties. A recombinant inbred line (RIL) mapping population involving a rice cultivar ‘Bengal’ and a US weedy rice accession ‘PSRR-1’ was evaluated for cold tolerance at both germination and seedling stages. Observations on germinating ability and seedling vigor were recorded under both low temperature (13oC) and optimum temperature …

Comparison Of Two Near-Isogenic Lines Of Bell Pepper (Capsicum Annuum): One Endornavirus-Infected And The Other Endornavirus-Free, Cesar Escalante Guardado
Comparison Of Two Near-Isogenic Lines Of Bell Pepper (Capsicum Annuum): One Endornavirus-Infected And The Other Endornavirus-Free, Cesar Escalante Guardado
LSU Master's Theses
Bell pepper (Capsicum annuum) is an economically important food crop cultivated worldwide. So far, all tested commercial cultivars have been shown to be infected with Bell pepper endornavirus (BPEV). Although BPEV does not cause apparent disease, the effect of this virus on bell pepper has not been investigated. A comparative study that included plant phenotype and some physiological characteristics was conducted with two near-isogenic lines (NIL) of the bell pepper cv. Marengo: one infected with BPEV and the other BPEV-free. The interaction of BPEV with a disease-causing virus of pepper, Pepper mild mottle virus (PMMoV), was also investigated. Differences in …
The Effects Of Aerobic Exercise And Lipolytic Stimulation On Skeletal Muscle And Adipose Expression Of Perilipin 3 (Plin3) In Individuals With Type 2 Diabetes And Women With Polycystic Ovary Syndrome, Jeffrey Daniel Covington
The Effects Of Aerobic Exercise And Lipolytic Stimulation On Skeletal Muscle And Adipose Expression Of Perilipin 3 (Plin3) In Individuals With Type 2 Diabetes And Women With Polycystic Ovary Syndrome, Jeffrey Daniel Covington
LSU Doctoral Dissertations
Ectopic lipid accumulation in skeletal muscle is linked with insulin resistance and type 2 diabetes (T2D). Neutral lipid is stored as lipid droplets, which are coated by lipid droplet coat proteins. One important class of these proteins are the perilipins. Little research has focused on perilipin 3 (PLIN3) and coatomer gtp-ases, theorized to be involved in PLIN3 directed lipid oxidation. Under lipolytic stimulation with epinephrine or palmitate, forskolin, and ionomysin (PFI), primary human myotubes taken from health non-T2D donors showed increased protein content levels of PLIN3. Concordantly, following endurance exercise in non-T2D males—an experimental paradigm shown to increase lipolysis—levels of …
Functional And Structural Analyses Of A Bacterial Antifreeze Protein, Chen Wang
Functional And Structural Analyses Of A Bacterial Antifreeze Protein, Chen Wang
LSU Doctoral Dissertations
Antifreeze proteins (AFPs) are a class of ice binding proteins (IBPs) that are expressed by different cold-adapted organisms to increase their freezing tolerance. AFPs have two major properties: thermal hysteresis and ice recrystallization inhibition. Here we report the functional and structural analyses of a bacterial AFP, IBPv. IBPv was originally secreted by a bacterium recovered from a deep glacial ice core drilled at Vostok Station, Antarctica. Our study showed that the recombinant protein rIBPv exhibited a thermal hysteresis of 2°C at concentrations higher than 50 µM, effectively inhibited ice recrystallization, and enhanced bacterial viability during freeze-thaw cycling. Circular dichroism scans …

Three Essays On Consumption Behavior, Credit, And Labor Supply Of Farm Households In Sub-Saharan Africa: Evidence From Uganda, Seydina Ousmane Sene
LSU Doctoral Dissertations
Consumption patterns, credit, and labor supply are determinants of human welfare, and also indicators of a country's economic progress, poverty, and inequalities. In this study, I review many of the stylized facts regarding consumption behaviors, credit, and the decision to engage in off-farm labor supply. I also put the life cycle model into an empirical model and perform testing. This is done in a three-essay format with a focus on the country of Uganda. In the first essay, I test whether farm households’ consumption behavior is consistent with an optimization process predicted by economic theory. In essay II, I evaluate …
The Roles Of Avr4 In Fungal Virulence,Cercosporin Biosynthesis And Its Potential Use In Host Induced Gene Silencing For Controlling Cercospora Leaf Blight Disease Of Soybeans, Josielle Santos Rezende
The Roles Of Avr4 In Fungal Virulence,Cercosporin Biosynthesis And Its Potential Use In Host Induced Gene Silencing For Controlling Cercospora Leaf Blight Disease Of Soybeans, Josielle Santos Rezende
LSU Doctoral Dissertations
The AVR4 effector, secreted by Cladosporium fulvum, has been demonstrated to be involved in pathogen virulence. Recent studies further demonstrated that Avr4 is highly conserved among several Cercospora species, indicating a potential important role of this gene in fungal virulence. Therefore, investigation to determine whether this fungal effector gene is present in Cercospora cf. flagellaris (previously known as C. kikuchii), the causal agent of soybean cercospora leaf blight (CLB) disease, and whether it plays any role in CLB disease development, is of great interest. In the present study, the Avr4 gene from C. cf. flagellaris was cloned and mutants lacking …
Organizational Misconduct Within The National Collegiate Athletic Association, Khirey Bennie Walker
Organizational Misconduct Within The National Collegiate Athletic Association, Khirey Bennie Walker
LSU Doctoral Dissertations
Prior research on organizational misconduct within intercollegiate athletics focuses on the penalties administered by the NCAA and types of violations committed by member institutions, rather than the engagement of misconduct and the role of the NCAA as a social-control agent. Consequently, the purpose of this dissertation is to analyze the relationship between social-control agents and potential wrongdoers (i.e., organizations), in addition to how the relationship affects the evolving line separating right from wrong. A three-paper multiple method examination has been conducted, including a historical analysis of NCAA enforcement, a qualitative framing analysis on the detailing of NCAA major infractions to …
Fibroblast Growth Factor 21 Is A Novel Protein Sensor In Pregnancy, Elizabeth Frost Sutton
Fibroblast Growth Factor 21 Is A Novel Protein Sensor In Pregnancy, Elizabeth Frost Sutton
LSU Doctoral Dissertations
The twenty-first century has experienced a shift in cause of death worldwide from communicable diseases to noncommunicable diseases. Interestingly, many of these implicated chronic diseases, such as cancer, diabetes, and cardiovascular disease, have been shown to be programmed in the womb. As first posited by the Barker Hypothesis, adverse exposures in utero can increase an individual’s risk for chronic disease later in life. Therefore, pregnancy is an opportune time for intervention to improve the health of future generations. Studies of exposures known to negatively impact infant health, e.g. states of overnutrition (obesity, diabetes, excess gestational weight gain) and undernutrition (starvation, …
Exploring Social Indicators Of Situational Interest In Physical Education And Activity Classes: Integration Of Interest And Self-Determination Theories, Joseph Opiri Otundo
Exploring Social Indicators Of Situational Interest In Physical Education And Activity Classes: Integration Of Interest And Self-Determination Theories, Joseph Opiri Otundo
LSU Doctoral Dissertations
It is clearly documented that physically active lifestyles result in numerous health benefits. Unfortunately, a majority of individuals do not meet recommended physical activity (PA) guidelines. Physical education (PE) courses provide avenues for students to increase PA. Teachers and public health officials identify the importance of student motivation constructs such as interest in promoting PA behaviors and other healthy life habits. The purposes of this dissertation were to advance the measurement of situational interest by investigating social indicators derived from self-determination theory (SDT), and to test a theoretical model that integrates interest theory and SDT. Two quantitative studies were designed …
Evolutionary History Of A Large-Genome Salamander Across Five Disjunct Regions Of The Southeastern United States, Catherine Elizabeth Newman
Evolutionary History Of A Large-Genome Salamander Across Five Disjunct Regions Of The Southeastern United States, Catherine Elizabeth Newman
LSU Doctoral Dissertations
The southeastern United States has a dynamic geologic history. Mountain range uplift, sea level fluctuations, and river basin evolution have shaped species geographic distributions in the region. My dissertation objectively identifies amphibian species with highly fragmented distributions in the Southeast (Chapter 2) and examines the phylogeographic history of one of those species, Plethodon serratus. This salamander species has a widely disjunct range across five regions: the Appalachians, the Ozarks, the Ouachitas, and two allopatric sites in Louisiana. Analyses of mitochondrial and nuclear loci (Chapter 3) showed that P. serratus is comprised of multiple genetic lineages, and the five regions are …
Evaluation Of A Role For Prolactin In The Recrudescense Of Ovarian Activity In Seasonally Anovulatory Mares, Erin Lea Oberhaus
Evaluation Of A Role For Prolactin In The Recrudescense Of Ovarian Activity In Seasonally Anovulatory Mares, Erin Lea Oberhaus
LSU Doctoral Dissertations
A series of experiments studied the possible role for prolactin in the spring-time recrudescence of ovarian activity in mares. The first experiment was based on cabergoline administration to seasonally anovulatory mares to prevent the seasonal rise in endogenous plasma prolactin to assess whether reduced prolactin altered onset of ovarian activity or first ovulation. Although prolactin concentrations were reduced, basal prolactin concentrations recovered from suppression by the time of the next injection (10 days later), even though low-dose sulpiride stimulation of prolactin was still suppressed by 85%. The subsequent experiment tested whether season affected the duration and degree of suppression produced …
Epigenetic Profiling Of Mammalian Retrotransposons, Arundhati Bakshi
Epigenetic Profiling Of Mammalian Retrotransposons, Arundhati Bakshi
LSU Doctoral Dissertations
Over evolutionary time, mammalian genomes have accumulated a large number of retrotransposons, making up about half of the genome in any given species. These retrotransposons are typically repressed by epigenetic mechanisms, one of the main ones being DNA methylation. It is well known that improper DNA methylation of retrotransposons can have unwanted consequences on nearby gene expression, and hypomethylation of retrotransposons has been frequently observed in various cancers. Nevertheless, it has been notoriously difficult to study retrotransposon loci individually due to the highly repetitive nature of their sequences. To address this issue, we have developed a novel protocol termed HT-TREBS …

Determining The Influence Of Imidacloprid And Glufosinate Ammonium On The Population Dynamics Of Twospotted Spider Mite Populations In Louisiana Cotton, Sebe Anthony Brown
LSU Doctoral Dissertations
Twospotted spider mites, Tetranychus urticae, is an important agricultural pest of many field crops worldwide. This study investigated the impacts of imidacloprid seed treatments on populations of twospotted spider mites while also investigating if exogenous applications of jasmonic acid can offset any hormone modulating effects caused by seed treatments. Imidacloprid seed treatments significantly increased cumulative adult mite days in 2013 but not 2015 or 2016 in the field. Applications of 10 millimolar jasmonic acid did not reduce mite severity or injury in all field trials. Imidacloprid seed treatments significantly increased all spider mite life stages in the laboratory while applications …
Structure-Based Prediction Of Protein-Protein Interaction Networks Across Proteomes, Surabhi Maheshwari
Structure-Based Prediction Of Protein-Protein Interaction Networks Across Proteomes, Surabhi Maheshwari
LSU Doctoral Dissertations
Protein-protein interactions (PPIs) orchestrate virtually all cellular processes, therefore, their exhaustive exploration is essential for the comprehensive understanding of cellular networks. Significant efforts have been devoted to expand the coverage of the proteome-wide interaction space at molecular level. A number of experimental techniques have been developed to discover PPIs, however these approaches have some limitations such as the high costs and long times of experiments, noisy data sets, and often high false positive rate and inter-study discrepancies. Given experimental limitations, computational methods are increasingly becoming important for detection and structural characterization of PPIs. In that regard, we have developed a …

Activity Of Benzobicyclon Herbicide In Common Louisiana Rice Production Practices, Benjamin M. Mcknight
LSU Doctoral Dissertations
A study was conducted at the LSU AgCenter H. Rouse Caffey Rice Research Station (RRS) to evaluate benzobicyclon herbicide application timing on water-seeded rice. Benzobicyclon was applied at seven different timings, at 246 g ai ha-1 in a water-seeded rice production system. Benzobicyclon controlled ducksalad above 90% when applied into the pinpoint flood. Barnyardgrass control was greater than 90% from applications made on pegging rice and immediately following pinpoint flood establishment. At 49 days after treatment (DAT), yellow nutsedge control exceeded 90% following benzobicyclon treatment with a pegging rice or pinpoint flood timing. Ducksalad control was greater than 90% following …
Epigenetic Response Of Imprinted Domains During Carcinogenesis, Corey Lane Bretz
Epigenetic Response Of Imprinted Domains During Carcinogenesis, Corey Lane Bretz
LSU Doctoral Dissertations
The first part of this work induced T-cell lymphoma in mice by employing a breeding scheme involving mouse strains expressing the KrasG12D oncoprotein and mice expressing cyclic recombinase from the mouse mammary tumor virus promoter. Imprinted domains were then systematically surveyed for DNA methylation changes during tumor progression using combined bisulfite restriction analysis and next-generation-bisulfite-sequencing. Hyper-or hypomethylation was detected at the imprinting control regions (ICRs) of the Dlk1, Peg10, Peg3, Grb10 and Gnas domains. These DNA methylation changes at ICRs were more prevalent and consistent than those observed at the promoter regions of well-known tumor suppressors, such as Mgmt, Fhit …

Examining The Impact Of Participating In A Nutrition-Education And Culinary Skills-Building Program On Intrinsic Motivation To Prepare Healthy Foods And Diet Quality In High School Adolescents, Derek Charles Miketinas
LSU Doctoral Dissertations
The objective of these studies was to develop a questionnaire that could measure the psychosocial constructs identified by the Self Determination Theory (SDT) as they relate to adolescents’ food preparation attitudes and their learning environment. The questionnaire included items that measured intrinsic motivation (IM), perceived competence (PC), relatedness, autonomy, and autonomy support. These studies explored the questionnaire’s validity, reliability, and ability to measure construct changes. The Adolescent Motivation to Cook Questionnaire (AMCQ) was developed in the first study to measure high school students’ IM and PC to prepare healthy foods, and their relatedness, autonomy and autonomy support within the classroom. …
Microbial Distributions And Survival In The Troposphere And Stratosphere, Noelle Celeste Bryan
Microbial Distributions And Survival In The Troposphere And Stratosphere, Noelle Celeste Bryan
LSU Doctoral Dissertations
Although bioaerosols in the lower altitudes of the atmosphere have been extensively studied, little is known about the distribution and nature of microorganisms at altitudes above the Earth’s surface. To examine the vertical distribution of microorganisms in the atmosphere, a helium balloon payload system was developed to sample bioaerosols at stratospheric altitudes of up to 38 km, where temperature, air pressure, relative humidity, and ultraviolet-C (UV-C) radiation conditions are similar to the surface of Mars. Bioaerosol concentrations between 3 and 29 km were similar to each other, ~three-fold lower than those in the convective boundary layer (CBL; 0-3 km; 1 …
Managerial Labor Mobility In The National Football League, Jeremy Joseph Foreman
Managerial Labor Mobility In The National Football League, Jeremy Joseph Foreman
LSU Doctoral Dissertations
Within the present dissertation, determinants of leader dismissals, promotions, and demotions are explored. A model of CEO dismissals is adapted to the context of the National Football League (NFL), whereby head coaches represent CEOs. Building upon empirical studies of the CEO dismissal model, a proxy is established which is representative of actual candidates to replace an executive rather than proxies based on industry and firm characteristics. Using the proxy for candidates provided statistically insignificant results that challenge the theoretical relationship between candidate availability and executive dismissals. Additionally, the present dissertation proposed and found empirical justification for incorporating an additional socio-political …
Kinetic And Kinematic Variables Related To Medial Elbow Joint Space In Collegiate Baseball Pitchers, Meghan Reid Jackson
Kinetic And Kinematic Variables Related To Medial Elbow Joint Space In Collegiate Baseball Pitchers, Meghan Reid Jackson
LSU Doctoral Dissertations
The ulnar collateral ligament (UCL) is a prime stabilizer in the elbow against valgus force. It is also a commonly injured structure in the overhead-throwing athlete. The majority of literature to date assesses the medial elbow by adding a valgus stress or evaluates the elbow after injury has occurred. The purpose of this dissertation is to explore static changes to the medial elbow and the relationship with the overhead throw. The first investigation sought to determine if there was a bilateral difference in the medial joint space of the elbow in general population college-aged students. There was no significant difference …
Maternal Fatty Acid And Inflammatory Status During Pregnancy Are Related To Infant Heart Rate And Heart Rate Variability, Merritt Leanne Drewery
Maternal Fatty Acid And Inflammatory Status During Pregnancy Are Related To Infant Heart Rate And Heart Rate Variability, Merritt Leanne Drewery
LSU Doctoral Dissertations
Early life heart rate (HR) and heart rate variability (HRV) reflect autonomic maturation. Intervention with n-3 long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy favorably affects fetal HR and HRV; similar observations have been reported with infant n-3 LCPUFA intake. Infant HR and HRV have not been assessed in relation to maternal fatty acid status during pregnancy. Further, exposure to intrauterine inflammation may underlie these observations, although this hypothesis has not been tested. The aim of this observational study was to explore associations between maternal fatty acid and inflammatory status during pregnancy and infant HR and HRV. Simple linear and …
