Antibiotics That Inhibit 30s Or 50s Ribosomal Subunit Formation: Hygromycin B, Quinupristin-Dalfopristin And Xrp 2868., Susan Mabe Mcgaha

Electronic Theses and Dissertations

Several antibiotics that prevent translation by binding to ribosomal subunits have been shown to also inhibit ribosomal subunit assembly (Champney and Tober 2003). The aminoglycoside hygromycin B was examined in Escherichia coli cells for inhibitory effects on translation and ribosomal subunit assembly. The streptogramin antibiotics quinupristin-dalfopristin and XRP 2868 (NXL 103) were examined for similar effects on these 2 cellular functions in antibiotic-resistant strains of Haemophilus influenzae, Staphylococcus aureus, and Streptococcus pneumoniae.

Pulse chase experiments were performed which verified slower rates of ribosomal subunit formation in drug treated cells. Hygromycin B exhibited a concentration dependent inhibitory effect …

The Long March Of The German 68ers: Their Protest, Their Exhibition, And Their Administration., Gracie M. Morton

Electronic Theses and Dissertations

The postwar children coming of age in the late 1960s in West Germany mounted a widesweeping socio-political protest against what they saw as the strangling silence of their parents, the Nazi generation. These protesters, referred to as the 68ers for their pivotal year, continued their struggle in following decades, incorporating an important and controversial exhibition, and finally culminating in their own administration thirty years from their defining moment. Using such diverse kinds of information as parliamentary debates, interviews, and contemporary criticism, this thesis explores the impact of the 68ers' initial protest and the influence they ultimately had on their nation …

The New Guideline For Goodwill Impairment, Nancy Jewel Swanson

Theses and Dissertations

Goodwill, for financial accounting purposes, is an intangible asset on the balance sheet that represents the excess of the amount paid for an acquired entity over the net fair value of the assets acquired. The Financial Accounting Standards Board has recently issued a new mandate. This new guideline eliminates annual amortization of goodwill and requires annual valuation for potential goodwill impairment and consequent writedown. Determining the amount of impairment requires management estimation, thus, allowing managerial discretion in developing the impairment amounts. Managerial discretion may then be used to manage earnings. Earnings management occurs when managers exercise their professional judgment in …

Purification And Structural Analysis Of Newcastle Disease Virus V Protein And Flowering Locus T (Ft) Protein, Swapna Jayapalan

Theses and Dissertations

Newcastle disease virus (NDV) is one of the paramyxovirus that has been studied at length since this virus infects the birds of all species. NDV is highly virulent in chickens and results in a high mortality rate because the V protein of NDV is found to inhibit the avian immune response system. No drugs are available for treating NDV therefore, determining the structure of V protein would help in developing a drug that can inactivate the V protein, thereby increasing the host immune response against viral infection. The research here is focused on purification and initial structural analysis of the …

The Young Lady's Consent, Christopher O. Kidder

LSU New Orleans Theses and Dissertations

This play is a translation and adaptation of a Spanish play originally written in 1806 by Leandro Fernández de Moratín, El sí de las niñas. Because that play was not available to English-speaking actors, I translated the work directly from the original Spanish. The resulting manuscript was not the finished product of this play, however. Through a series of workshops with actors trained in a physical method of theatre I devised in order to modernize classic works to a more modern audience's tastes, the script morphed and grew into the play that follows.

Fulfilling The Drive: Dutch Morial And The 1982 New Orleans Mayoral Election, Daniel Braud

LSU New Orleans Theses and Dissertations

This study examines the impact of racial politics on the New Orleans mayoral election of 1982. Ernest "Dutch" Morial, the city's first black mayor, sought re-election against a popular white candidate, Ron Faucheux, and a well-liked black candidate, William Jefferson. Race played an integral role throughout the campaign as Morial continually battled attacks from both the conservative white community and the traditional black politicians, all of whom resented the oftentimes brash mayor and his push for change. Controversy also surrounded his handling of the police strike of 1979 and the Fischer Housing Project shootings of 1980. This study argues that …

Regulation Of The Lactoperoxidase System In The Airway, Miryam A. Fragoso

Open Access Dissertations

The lactoperoxidase (LPO) antimicrobial system has been shown to play an important role in maintaining sterile conditions in several tissues including the mammary gland, the salivary gland, and the airway. The LPO system in the airway consists of the enzyme LPO and its substrates hydrogen peroxide and an anion. LPO catalyzes the oxidation of a halide or pseudohalide ion for example SCN-or I- by hydrogen peroxide producing a product, OSCN- or OI- which have antibacterial, antifungal, and antiviral properties. In order to have a functional antimicrobial system all the components need to be present at appropriate concentrations. The LPO system …

Study Of The Reproducibility Of Proteomics Methods And Variability Of Fruit Fly Proteomes., Thomas Franklin Culwell

Theses and Dissertations

The reliability of biomarker discovery by means of proteomics has been called into question. It was speculated that "background noise" variation resulting from differences in preparation and handling of samples and proteome dynamics may mask subtle, yet important, differences due to the biological condition. Little is understood about complex proteomes and their variability. A critical aspect of proteomic biomarker research that is largely unexplored is the comparative reproducibility of certain methods such as two-dimensional gel electrophoresis and liquid chromatography/mass spectrometry. In particular, with liquid chromatography/mass spectrometry, it is not known whether variability in peptide quantitation is dependent on any of …

Bacterial Auto-Aggregation And Co-Aggregation In Activated Sludge, Fei Chen

All Theses

Microbial auto-aggregation and co-aggregation, leading to biofilm or floc formation, widely occur in natural systems. This study was conducted to investigate the extent of bacterial auto-aggregation and co-aggregation in activated sludge and their contributions in activated sludge floc formation. In this study, an activated sludge sample was separated into a supernatant part (planktonic community) and a sediment part (floc community) by centrifugation at 650_g for 2 minutes. 197 strains were isolated from both communities. These isolates belong to 18 phylotypes based on molecular identifications. Similar phylogenetic distributions of these isolates were observed in planktonic and floc communities, suggesting a similar …

Property Measurements And Evaluation Of Heat Leak, Nathan Race

All Theses

Heat transport in capillary wick structures is an important parameter in loop heat pipe (LHP) design. The purpose of this study was to investigate the conductive heat leak in operating capillary wick structures. The heat leak is the portion of applied heat load conducted through the wick in spite of the convection of working fluid. Four sintered 316 stainless steel wicks were tested for porosity, effective thermal conductivity, pore size, and heat leak. Pore sizes were found to correlate well with the nominal pore size and pores were very narrowly distributed within a size range of approximately 1-10μm. Effective thermal …

E. B. White’S Environmental Web, Lynn Overholt Wake

Department of English: Dissertations, Theses, and Student Research

E. B. White called Walden his favorite book and found in it “an invitation to life’s dance.” To read White ecocritically is to accept a similar invitation to broaden our environmental imagination. Although one or two of his essays are often anthologized as nature writing, critics have not read White environmentally. While emphasizing White’s three books for children, this dissertation reads across genre lines to examine his lifelong work. Drawing on Laurence Buell’s prismatic term, the study explores how White’s engagement with the natural world contributes to the renewal of our collective environmental imagination. Examining White’s affinity for animals, evident …

Overwhelming Systems, Meghan Oconnor

All Theses

My work portrays my own social and cultural desires, fears, and experiences. I employ a narrative format that shows childhood cartoon influences to attract viewers and visual complexity to sustain them. I depict fear, tension, struggle, and isolation to reveal deception, which stems from a response to structures of power. It is a representation, a questioning, and/ or a critique of the state of today's human nature and subsequent condition. I employ images of animals as a stand-in for the human figure, feeling or persona. Mechanical devices are metaphors of harmful systems of culture or power. The illusion of transparency …

Thermodynamic Evidence That Ganglioside-Mediated Insertion Of Botulinum A Into The Cholinergic Nerve Ending May Precede Endocytosis And Acidification: A Langmuir Film Study, Bradley Adam Strongin

Theses and Dissertations

Botulinum Neurotoxin (BoNT) is one of the most potent toxins known to human kind. The Atomic Force Microscope (AFM) was employed to investigate the conditions under which BoNT type A heavy chain would bind and/or insert into mica supported dipalmitoylphosphatidylcholine (DPPC) lipid bilayers. As an alternate technique, DPPC/GT1b or total ganglioside extract (80:20) monolayers of a Langmuir Blodgett (LB) Trough were adapted to be artificial membrane models for toxin insertion studies. We conclude that LB monolayer studies are a promising candidate for BoNT/A membrane insertion investigation. Botulinum neurotoxin serotype A insertions into the LB monolayers in the presence of BoNT/A …
