Microfluidic Device For Motility And Osmolality Analysis Of Zebrafish Sperm, Jacob Ethan Beckham Jan 2016

Microfluidic Device For Motility And Osmolality Analysis Of Zebrafish Sperm, Jacob Ethan Beckham

LSU Master's Theses

An increasing number of laboratories are evaluating sample quality via motility analysis by means of computer-assisted sperm analysis (CASA) after sperm activation by manual dilution and mixing. Even with the use of CASA, due to user variation, there is a lack of control over the activation process, resulting in inconsistent motility analysis. Low sample volume (~1-2µL), and a short motility duration (burst motility of less than 15s) add to the complexity of these difficulties. The objectives of this study were to develop a microfluidic device with the capabilities to (1) standardize the method of activation for zebrafish sperm so that …

The Effect Of Artificial Light On The Community Structure And Distribution Of Reef-Associated Fishes At Oil And Gas Platforms In The Northern Gulf Of Mexico, Victoria Anne Barker Jan 2016

The Effect Of Artificial Light On The Community Structure And Distribution Of Reef-Associated Fishes At Oil And Gas Platforms In The Northern Gulf Of Mexico, Victoria Anne Barker

LSU Master's Theses

The northern Gulf of Mexico (GOM) contains approximately 2,500 oil and gas platforms, resulting in one of the largest de facto artificial reef systems in the world. As of 2013, 1,227 additional structures had ceased to produce oil and gas and have been decommissioned and removed. While active platforms are lit by high-pressure mercury vapor lights, inactive platforms are only minimally lit for navigation. The positively phototaxic behavior of many fish species causes lit oil platforms to act as fish attraction devices, especially at night. Though a variety of fish species have been reported near these structures, changes in fish …

Efficacy And Feasibility Of Alginate Bait For The Louisiana Commercial Blue Crab (Callinectes Sapidus) Fishery, Elizabeth Lorraine Clowes Jan 2016

Efficacy And Feasibility Of Alginate Bait For The Louisiana Commercial Blue Crab (Callinectes Sapidus) Fishery, Elizabeth Lorraine Clowes

LSU Master's Theses

Louisiana leads all U.S. states in blue crab (Callinectes sapidus) landings, but high fuel and bait costs have hindered commercial fishing productivity of Louisiana in recent years. The primary baitfish, Atlantic menhaden (Brevoortia tyrannus), has steadily increased in price and decreased in availability, while crab prices remain low. To reduce costs for fishermen, an alternative bait was developed that incorporates shrimp waste into a semi-rigid alginate matrix. Lab testing and preliminary field tests show that shrimp-alginate bait may be a suitable alternative to menhaden for Louisiana crab fishermen. I evaluated bait performance by conducting field sampling to compare catch rates …

Relative Resistance To Breaking Of Pinus Taeda L. And Pinus Palustris, Cory Glenn Garms Jan 2016

Relative Resistance To Breaking Of Pinus Taeda L. And Pinus Palustris, Cory Glenn Garms

LSU Master's Theses

Patterns from hurricane damage give an indication that longleaf pine (Pinus palustris) is more windfirm than loblolly pine (Pinus taeda). Tree windfirmess has been attributed to many factors including species and material properties like wood strength and stiffness. Because longleaf pine wood is stronger and stiffer than loblolly pine wood, this study used static winching methodology to see if these properties account for differences in windfirmness by measuring bending force required to break stems (MMAX). Stress-strain diagrams were constructed for pulled trees to explore how they behave under increasing loads. Based on these diagrams, it appears that living trees can …

Metric Variation In The Human Sacrum: Costal Process Length Among Black And White South Africans, Christy Rose Wayne Jan 2016

Metric Variation In The Human Sacrum: Costal Process Length Among Black And White South Africans, Christy Rose Wayne

LSU Master's Theses

Considerable attention has been given to the measureable differences that exist between different human populations in the size and shape of the pelvis, with Africans having a narrower pelvis than Europeans. By collecting data on sacral breadth from a South African skeletal population, this study (1) tests the hypothesis that African blacks possess a narrower sacrum, and by inference pelvis, than whites and (2) considers whether the size variation between blacks and whites is due to nutritional, historical and social differences, to a genetic basis related to climatic adaptation, or to both. White South Africans were found to possess a …

Reactivity Of Iron-Sulfur Proteins With Nitric Oxide, Md Julkernine Julfiker Jan 2016

Reactivity Of Iron-Sulfur Proteins With Nitric Oxide, Md Julkernine Julfiker

LSU Master's Theses

Iron-sulfur ([Fe-S]) proteins are widely distributed in the biological systems. These proteins are involved in diverse fundamental life processes such as photosynthesis, respiration, ribosome biogenesis, DNA synthesis, and repair. Dysfunction of these proteins or their biogenesis has been implicated in causing cardiovascular diseases, neurodegenerative diseases, and various cancers. Iron-sulfur proteins are highly sensitive to nitric oxide (NO) and readily form dinitrosyl iron complexes (DNICs) upon exposure. Restoration of the iron-sulfur cluster in the NO-modified protein requires a two-step repair process. The first step is to remove DNICs from proteins. The second step is to re-assemble the iron-sulfur cluster in proteins. …

Investigating The Structure Of The Papain-Inhibitor Complex Using Spr And Nmr, Margaret Sara Thomasson Jan 2016

Investigating The Structure Of The Papain-Inhibitor Complex Using Spr And Nmr, Margaret Sara Thomasson

LSU Doctoral Dissertations

Cysteine proteases (CPs) are enzymes with a nucleophilic thiol in their active sites. Inhibitors of cysteine proteases (ICPs) occur naturally in bacterial pathogens and some protozoa. In parasites, ICPs are often virulence factors, contributing to the formation and survival of amastigotes within host cells. These amastigotes have higher CP activity, therefore making both ICPs and CPs potential drug targets. Despite great genetic variability, ICPs contain highly conserved structural features, including a series of defined loops that play a significant role in binding CPs. Papain, a CP from Carica papaya, complexes with ICP from Leishmania mexicana. Although the individual 3-D structures …

Role Of An Adenylyl Cyclase Isoform In Alcohol's Effect On Cyclic Amp Regulated Gene Expression In Mammalian Cells, Rebecca Ann Hill Jan 2016

Role Of An Adenylyl Cyclase Isoform In Alcohol's Effect On Cyclic Amp Regulated Gene Expression In Mammalian Cells, Rebecca Ann Hill

LSU Doctoral Dissertations

Research suggests that the cyclic AMP (cAMP) signaling pathway including CREB-CRE regulated expression of various genes is implicated in the predisposition to and development of alcoholism in humans. Alcohol also induces changes in inflammatory and immune responses; these changes increase the incidence of pneumonias and other infections, which can negatively affect recovery from infections. Cyclic AMP (cAMP) is known for its immunosuppressive effects and is also required for proper development of the immune system. Previous work in our laboratory has demonstrated that ethanol enhances the activity of adenylyl cyclase (AC) in an isoform-specific manner; type 7 AC (AC7) is most …

Characterization Of Boundary Element-Associated Factors Beaf-32a And Beaf-32b And Identification Of Novel Interaction Partners In Drosophila Melanogaster, S. V. Satya Prakash Avva

LSU Doctoral Dissertations

Regulatory elements are DNA sequences which have specialized activities that coordinate the functions of the genome. Promoters, enhancers, locus control regions, boundary elements (or insulator elements) are examples of DNA sequences that have regulatory properties. In transgenic assays insulator elements have been shown to block communication between regulatory regions, such as enhancers and promoters, when placed between these sequences and also protect genes from position effects when bracketing them, thereby affecting gene expression. Insulator sequences are bound by insulator proteins that direct the function of these sequences. One such insulator protein is the Boundary Element Associated Factor-32 (BEAF-32), a 32 …

Use Of Protein Crosslinking And Tandem Mass Spectrometry To Study The Psbo, Psbp And Psbq Extrinsic Proteins Of Higher Plant Photosystem Ii, Manjula Priyadarshini Mummadisetti

LSU Doctoral Dissertations

Photosystem II (PSII) is a light-driven, water plastoquinone oxidoreductase present in all oxygenic photosynthetic organisms. The oxygen evolution process is catalyzed by the Mn4CaO5 cluster and an ensemble of intrinsic and extrinsic proteins which are associated with the photosystem. This metal cluster is stabilized and protected from exogenous reductants by the extrinsic proteins, PsbO, PsbP and PsbQ in higher plants, which are present on the lumenal face of PSII. No crystal structure for the higher plant PSII is currently available; consequently, the binding locations of these extrinsic proteins in PSII remain elusive. We have used chemical-crosslinkers Bis (sulfosuccinimidyl) suberate (BS3) …

Design And Implementation Of Qcm Virtual Sensing Schemes For Analyses Of Volatile Organic Compounds, Nicholas Colby Speller Jan 2016

Design And Implementation Of Qcm Virtual Sensing Schemes For Analyses Of Volatile Organic Compounds, Nicholas Colby Speller

LSU Doctoral Dissertations

Sensor arrays have evolved as powerful approaches for providing detection and discrimination of volatile organic compounds (VOCs) as required across numerous analytical applications. Such systems typically comprise a number of cross reactive sensor elements, which generate analyte specific response patterns upon exposure to VOCs, and are known as multisensor arrays. When evaluated using statistical methods, these response patterns facilitate classification of VOCs. As an alternative, a single dynamically operated sensor could also be used to generate analyte specific response patterns. This approach is known as a virtual sensor array (VSA) and can exhibit significant advantages when compared to MSAs. Some …

The Representation Of Disability In The Music Of Alfred Hitchcock Films, John T. Dunn Jan 2016

The Representation Of Disability In The Music Of Alfred Hitchcock Films, John T. Dunn

LSU Doctoral Dissertations

Several of Alfred Hitchcock’s movies feature characters with disabilities. Often, these characters are protagonists, and Hitchcock systematically manipulates his audiences to identify with these characters through the editing process, sound effects, and music. This dissertation will analyze the ways music represents various disabilities in three Hitchcock films. Vertigo (1958) addresses obsession and phobia as its main themes, whereas Psycho (1960) investigates obsession and madness. Finally, The Man Who Knew Too Much (1956) explores muteness, hysteria, and identity in the context of two pieces of diegetic music. Hitchcock made careful notes for the music in his films; songs represent disability through …
