Effects Of Mimic Artificial Oyster Reefs On The Ecology Of Juvenile Fishes In Marsh Ponds: A Before-After-Control-Impact Analysis, Steven B. Garner Jan 2012

Effects Of Mimic Artificial Oyster Reefs On The Ecology Of Juvenile Fishes In Marsh Ponds: A Before-After-Control-Impact Analysis, Steven B. Garner

LSU Master's Theses

I sought to assess the enhancement potential of mimic artificial oyster reefs (MAORs) on trophic dynamics of juvenile estuarine fishes in marsh ponds. Tropic dynamics were investigated by determining the impacts of MAOR addition on meiofauna and macrofauna and then comparing these results to the gut contents and condition of four abundant estuarine fishes: Atlantic croaker (Micropogonias undulatus), bay whiff (Citharichthys spilopterus), sand seatrout (Cynoscion arenarius), and pinfish (Lagodon rhomboides). Samples were collected every other month for two years (March 2009 – 11) employing a Before-After-Control-Impact (BACI) design. Halfway through the experiment (March 2010), two mud sites in two marsh …

Cluster Based Jamming And Countermeasures For Wireless Sensor Network Mac Protocols, David Trammell Jan 2012

Cluster Based Jamming And Countermeasures For Wireless Sensor Network Mac Protocols, David Trammell

LSU Doctoral Dissertations

A wireless sensor network (WSN) is a collection of wireless nodes, usually with limited computing resources and available energy. The medium access control layer (MAC layer) directly guides the radio hardware and manages access to the radio spectrum in controlled way. A top priority for a WSN MAC protocol is to conserve energy, however tailoring the algorithm for this purpose can create or expose a number of security vulnerabilities. In particular, a regular duty cycle makes a node vulnerable to periodic jamming attacks. This vulnerability limits the use of use of a WSN in applications requiring high levels of security. …

Optimal Cultural Practices For Processed Sweetpotato Products, Cody Derek Smith Jan 2012

Optimal Cultural Practices For Processed Sweetpotato Products, Cody Derek Smith

LSU Master's Theses

As the sweetpotato industry moves towards more processed products, there is a need to develop strategies in which to optimize total yield and reduce costs. Unlike the fresh market product, desirable processing roots are larger in size and overall tonnage is preferred over aesthetic appeal. Plant spacing and row width along with planting dates and harvest dates are believed to affect the size and tonnage of sweetpotato roots. The Beauregard and Evangeline varieties were planted at an early planting date (June 1) and a late planting date (July 1) on 38 and 42 inch row spacing. Harvests were at ~125 …

The Use Of A Mixed Chlorella Cyanobacteria Culture As A Protein Source For Aquaculture, Marjan Sadat Mohtashamian Jan 2012

The Use Of A Mixed Chlorella Cyanobacteria Culture As A Protein Source For Aquaculture, Marjan Sadat Mohtashamian

LSU Master's Theses

The increase in the global demand for fish feed in the last decades has resulted in the over exploitation of natural resources to produce more fishmeal supplies for aquaculture industry. The supply issues and high prices of fishmeal products have raised the incentives to seek for suitable alternatives to replace fishmeal protein. As a by-product of biofuel production process, residual microalgal biomass may be a low cost feed ingredient to the aquaculture diet. The potential of the use of a post lipid extraction Chlorella vulgaris/Leptolyngbya sp. Co-Culture (Louisiana co-culture) as a protein source in aquaculture feeds could help offset fishmeal. …

Mechanisms By Which Exercise Training Attenuates Blood Pressure In Animals: Roles Of Cytokines, Oxidative Stress, And Glycogen Synthase Kinase-3Â, Deepmala Agarwal

LSU Doctoral Dissertations

Hypertension is a chronic multifactorial condition with high morbidity and mortality rates, currently affecting about one billion people worldwide. Currently available anti-hypertensive medications are found to be effective in reducing blood pressure (BP), but still more than 50% of those diagnosed with hypertension fail to respond to these anti-hypertensive regimens. Although hypertension has multiple etiologies, physical inactivity has been found to have strong correlation with the disease, so exercise has recently been recommended as a part of lifestyle modifications for all hypertensive patients. Therefore, the present series of in vivo and in vitro studies were undertaken to gain more insight …

A Novel Rna Extraction Method For Cyanobacteria, Zenghui Zhang Jan 2012

A Novel Rna Extraction Method For Cyanobacteria, Zenghui Zhang

LSU Master's Theses

Research on production of polyhydroxyalkanoates (PHA) by microorganisms has captured attention over the last two decades, since PHA have similar properties as petroleum-based thermoplastics, yet are close to carbon neutral and made from renewable sources. Cyanobacteria are considered to be good PHA producers because of their simple nutrient requirements (mainly water, sunlight and CO2) and fast cell growth. However, knowledge of metabolisms behind PHA production by cyanobacteria is limited. Therefore, gene expression analysis of cyanobacteria is required to get a thorough understanding at the molecular level, and gene expression analysis requires the extraction of high quality RNA. Extracting high quality …

Arabidopsis Pht1; 5 Plays An Integral Role In Phosphate Homeostasis, Aaron P. Smith, Vinay K. Nagarajan, Kashchandra G. Raghothama

Faculty Publications

The mobilization of inorganic phosphate (Pi) in planta is a complex process regulated by a number of developmental and environmental cues. Plants possess many Pi transporters that acquire Pi from the rhizosphere and translocate it throughout the plant. A few members of the high-affinity Pht1 family of Pi transporters have been functionally characterized and, for the most part, have been shown to be involved in Pi acquisition. We recently demonstrated that the Arabidopsis Pi transporter, Pht1;5, plays a key role in translocating Pi between tissues. Loss-of-function pht1;5 mutant seedlings accumulated more P in shoots relative to wild type but less …

Blood pressure is a heritable trait influenced by several biological pathways and responsive to environmental stimuli. Over one billion people worldwide have hypertension (≥140mmg Hg systolic blood pressure ≥90mmg Hg diastolic blood pressure). Even small increments in blood pressure are associated with an increased risk of cardiovascular events. This genome-wide association study of systolic and diastolic blood pressure, which used a multi-stage design in 200,000 individuals of European descent, identified sixteen novel loci: six of these loci contain genes previously known or suspected to regulate blood pressure (GUCY1A3 GUCY1B3, NPR3 C5orf23, ADM, FURIN FES, GOSR2, GNAS EDN3); the other ten …

Dietary-Resistant Starch Improves Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen, Michael J. Keenan, Anne Raggio, Cathy Williams, Roy J. Martin

Faculty Publications

Scope: Dietary prebiotics show potential in anti-diabetes. Dietary resistant starch (RS) has a favorable impact on gut hormone profiles, including glucagon-like peptide-1 (GLP-1) consistently released, a potent anti-diabetic incretin. Also RS reduced body fat and improved glucose tolerance in rats and mice. In the current project, we hypothesize that dietary-resistant starch can improve insulin sensitivity and pancreatic β cell mass in a type 2 diabetic rat model. Altered gut fermentation and microbiota are the initial mechanisms, and enhancement in serum GLP-1 is the secondary mechanism. Methods and results: In this study, GK rats were fed an RS diet with 30% …

Although thiazolidinediones (TZD) effectively improve hyperglycemia and increase adiponectin, a proinsulin-sensitizing adipokine, they also increase adipogenesis via peroxisome proliferator-activated receptor (PPAR)γ induction, which may be undesirable. Recent safety concerns about some TZD have prompted the search for next generation agents that can enhance glycemic control and adiponectin independent of PPARγ or adipogenesis. Reminiscent of TZD action, a human adenovirus, adenovirus 36 (Ad36), up-regulates PPARγ, induces adipogenesis, and improves systemic glycemic control in vivo. We determined whether this effect of Ad36 requires PPARγ and/or adipogenesis. Glucose uptake and relevant cell signaling were determined in mock-infected or human adenoviruses Ad36 or Ad2-infected …

Aebp2 As An Epigenetic Regulator For Neural Crest Cells, Hana Kim, Keunsoo Kang, Muhammad B. Ekram, Tae Young Roh, Joomyeong Kim

Faculty Publications

Aebp2 is a potential targeting protein for the mammalian Polycomb Repression Complex 2 (PRC2). We generated a mutant mouse line disrupting the transcription of Aebp2 to investigate its in vivo roles. Aebp2-mutant homozygotes were embryonic lethal while heterozygotes survived to adulthood with fertility. In developing mouse embryos, Aebp2 is expressed mainly within cells of neural crest origin. In addition, many heterozygotes display a set of phenotypes, enlarged colon and hypopigmentation, similar to those observed in human patients with Hirschsprung's disease and Waardenburg syndrome. These phenotypes are usually caused by the absence of the neural crest-derived ganglia in hindguts and melanocytes. …
