Experimental Design, Synthesis And Application Of Molecular Micelle Modified Polymeric Nanoparticles For Drug Delivery Systems And Free Radical Detection, Gabriela M. Ganea Visser

LSU Doctoral Dissertations

Biodegradable and biocompatible polymeric nanoparticles such as poly (lactide-co-glycolide) (PLGA) nanoparticles have been extensively studied as drug delivery systems for a variety of pharmaceutical agents. Nanoparticle surface properties are primarily determined by the emulsifiers used in the synthesis process, which have a significant impact on nanoparticle physico-chemical and biological properties. Anionic amino acid – based molecular micelles were used in the emulsification process to prepare monodisperse, small (below 100 nm) PLGA nanoparticles with a well defined spherical shape. Such molecular micelle – modified nanoparticles were used as drug carriers for delivery of antioxidants. Thymoquinone is a natural antioxidant, and an …

Influence Of Cultural Practices And Herbicides On Torpedograss [Panicum Repens (L.) Beauv.] Infestation In Centipedegrass [Eremochloa Ophiuroides (Munro, Hack)], James Taverner

LSU Master's Theses

Torpedograss (Panicum repens L. Beauv.) is a common weed problem along the Gulf Coast in highly managed turf. Non-selective herbicides are currently used to control torpedograss within centipedegrass [Eremochloa ophiuroides (Munro) Hack.] and St. Augustinegrass [Stenotaphrum secundatam (Walt.) Kuntze], but turfgrass injury can be extensive. Research was conducted to evaluate torpedograss and centipedegrass response to the application of the selective, post-emergence herbicides quinclorac, sethoxydim, and clethodim. Quinclorac applied at 0.42 kg ai ha-1 three times 4 wks apart reduced torpedograss to 25% coverage (55% of control) 10 weeks after initial treatment (WAIT), but re-establishment was rapid and by 16 WAIT …

Relationship Of Maternal Serum Fatty Acids And Body Mass Index, Emily Fontenot Gilbert Jan 2009

Relationship Of Maternal Serum Fatty Acids And Body Mass Index, Emily Fontenot Gilbert

LSU Master's Theses

Maternal supply of nutrients is critical for the developing fetus during all stages of gestation. The altered lipid metabolism that is often seen in pregnancies complicated by obesity and insulin resistance may negatively impact maternal supply to the fetus. More women are entering pregnancy overweight or obese and recently body mass index (BMI) has been found to be a positive predictor for decreased maternal plasma phospholipid concentrations of the long-chain polyunsaturated fatty acids (LCPUFA) docosahexanoic acid (DHA) and arachidonic acid (ARA). These nutrients play important roles in early development and their availability is critical to fetal growth and development. The …

Insights Into The Streptomycete Conjugation Mechanism And Interstrain Inhibitor Production By The Sweet Potato Pathogen Streptomyces Ipomoeae, Jing Wang Jan 2009

Insights Into The Streptomycete Conjugation Mechanism And Interstrain Inhibitor Production By The Sweet Potato Pathogen Streptomyces Ipomoeae, Jing Wang

LSU Doctoral Dissertations

Conjugation in Streptomyces invokes a unique mechanism involving few plasmid-encoded loci. Transfer of circular plasmid pIJ101 requires only a tra gene, and a cis-acting locus clt. Here, I investigated whether the transfer genes of pIJ101 could promote transfer of a linear plasmid. While pIJ101 Tra could transfer circularized versions of the linear plasmid containing clt, the linear plasmid itself could not be transferred efficiently by Tra. All plasmids isolated from transconjugants appeared to be circular regardless of the configuration of the plasmid in the initial donor cells. However the linear plasmid could be transferred in linear form from JW1, which …

Tnf-Alpha Inhibition Of Adiponectin Expression By Targeting Ppar-Gamma And C/Ebp In Adipocytes, Yanning Wang

LSU Master's Theses

Chronic inflammation is involved in the adipose tissue dysfunction through regulation of endocrine and storage function of adipocytes. As a representative proinflammatory cytokine, TNF-α was reported to inhibit expression of adiponectin. However, the mechanism of inhibition remains to be identified. Here, we provide experimental evidence that TNF-α inhibits adiponectin at both transcriptional and posttranscriptional levels. In three animal models (aP2-P65, ob/ob and high fat diets-fed mice), an increase in TNF-α expression was associated with a decrease in adiponectin expression. In 3T3-L1 adipocytes, TNF-α inhibition of adiponectin was observed at mRNA and protein levels. Luciferase reporter assay and mRNA stability tests …

Collpas As Activity Hotspots For Frugivorous Bats (Stenodermatinae) In The Peruvian Amazon: Underlying Mechanisms And Conservation Implications, Adriana Bravo Ordonez Jan 2009

Collpas As Activity Hotspots For Frugivorous Bats (Stenodermatinae) In The Peruvian Amazon: Underlying Mechanisms And Conservation Implications, Adriana Bravo Ordonez

LSU Doctoral Dissertations

In western Amazonia, large numbers of frugivorous bats regularly visit natural forest clearings known locally as collpas (also called clay licks or mineral licks). Bats arrive at collpas to drink water that has accumulated in depressions created by larger mammals that consume soil. Although collpa visitation by bats appears relatively common in western Amazonia, little is known about its causes and its ecological implications. In this dissertation I describe general and seasonal patterns of collpa visitation by frugivorous bats in the Peruvian Amazon, and I investigate potential explanations for this unique behavior. Regardless of season, collpas seem to be activity …

Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard Jan 2009

Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard

LSU Master's Theses

Gastrointestinal nematode (GIN) parasitism is a problem for small ruminant producers. Haemonchus contortus is the most detrimental because of substantial economic losses. Over the past decades, chemical anthelmintics have been used to control GINs. Recently, GINs have developed resistance to most anthelmintics, and now reliance on anthelmintics is not possible. Alternative control methods are needed. Also, the use of fewer chemicals in agricultural products has called for alternative methods to be less synthetic and more organic. One promising alternative method is the feeding of condensed tannin (CT) containing forages as either fresh forage or dried products such as hay, ground …

Biogenesis Of Iron-Sulfur Clusters And Intracellular Iron Metabolism, Jacob Philip Bitoun Jan 2009

Biogenesis Of Iron-Sulfur Clusters And Intracellular Iron Metabolism, Jacob Philip Bitoun

LSU Doctoral Dissertations

Iron-sulfur ([Fe-S]) clusters represent one of natures most diverse and ubiquitous protein prosthetic groups. [Fe-S] proteins are integral for diverse biological processes. Reconstitution of apo-proteins can occur by exogenously adding excess iron and sulfide. However, due to the toxicity of iron and sulfide, it is most likely that proteins coordinate [Fe-S] cluster assembly in cells. The first part of this dissertation addressed the iron donor for [Fe-S] cluster assembly. Recently, it has been shown that IscA is capable of binding iron with an association constant of 3.0 x 1019M-1. In addition, iron-loaded IscA is capable of …

Comorbid Psychopathology In Individuals With Autism Spectrum Disorders And Intellectual Disabilities, Santino Vincent Lovullo Jan 2009

Comorbid Psychopathology In Individuals With Autism Spectrum Disorders And Intellectual Disabilities, Santino Vincent Lovullo

LSU Master's Theses

While there has been an abundance of research investigating Autism Spectrum Disorders (ASD) in children, very little emphasis has been placed on ASD in adults, especially in regards to comorbid psychopathology. This is of great concern considering that ASD often co-occurs with intellectual disability (ID), and that both may serve as risk factors for additional psychopathology. While instruments exist that measure comorbid psychopathology in adults with ID, these scales are not targeted to the unique expression of comorbidity in adults with ID and ASD. The Autism Spectrum Disorders-Comorbidity for Adults (ASD-CA) was devised for this reason. This paper begins with …

Evaluation Of Pectin Methylesterase And Lactobacillus Spp. Isolated From Tabasco Peppers (Capsicum Frutescens L.), Sonja Tanee Jones

LSU Doctoral Dissertations

One of the major concerns of the hot sauce manufacturers is separation of sediments and layering of the sauce. Separation is an undesirable production condition because consumers view this as a defect which consequently increases manufacturing costs. Pectins play an important role in pepper processing since it forms gels and influences the final viscosity of the sauce. Hence, its integrity during processing influences the quality of the final product. Failures in pectin stability can sometimes be related to the presence of enzymes. Understanding how the pectin enzymes function during fermentation of pepper sauce is a necessary step in controlling the …
