Tandem Conjugate Addition -- Cyclization Reactions Of L-Methyl Prolinate With α,β-Unsaturated Ketones Catalyzed By L-Proline, Sergio Sandoval Jan 2008

Tandem Conjugate Addition -- Cyclization Reactions Of L-Methyl Prolinate With α,β-Unsaturated Ketones Catalyzed By L-Proline, Sergio Sandoval

Open Access Dissertations

L-methyl prolinate and various α,β-unsaturated ketones were reacted by a tandem sequence of conjugate addition and subsequent autocatalytic intramolecular cyclization to yield 1,3-dicarbonyl-pyrrolizidine ring systems in modest yield. This methodology represents a tandem and green preparative reaction sequence where L-proline is self-generated as an organocatalyst subsequent to the first step and prior to the second step of the process. This sequence of reactions is a one-pot, tandem, and green preparative reaction for the synthesis of various pyrrolizidine derivatives which can be performed in a general and simple way under solventless and room temperature conditions. This methodology is modest yielding and …

Study On The Nonenzymatic Glycation Of Nucleosides/Nucleotides And Proteins With Sugars: An In Vitro Investigation Of Advanced Glycation Endproducts (Ages) Formation, Yuyuan Li

Open Access Dissertations

Advanced glycation endproducts (AGEs) are a complex and heterogeneous group 1 of compounds formed by the nonenzymatic reactions of the carbonyl groups of reducing sugars with the free amino groups of biomolecules. Nonenzymatic reactions can occur in vitro and in vivo and affect the structure, function and conformation of many biomolecules, and AGEs has been suggested to associate with the pathogenesis of various disease such as diabetes and Alzheimer disease. The increased number of reports on the nonenzymatic glycation of proteins and nucleic acids has generated great interest in the methods for characterization of AGEs. The lack of universally applicable …

Microstructure Studies In Synthetic And Bio-Colloids, Imaging And Applications, Ashish Kumar Jha

Open Access Dissertations

The mean size of CTAB/HDBS mixed surfactant vesicles confined into the three-dimensional voids generated by the random close packing (RCP) of polystyrene beads, shows a systematic decrease as the characteristic confinement length scale is reduced. The RCP of polystyrene beads of radius Rb = 1.5μm, 0.25μm and 0.1μm, creates voids of characteristic dimensions R ∼ 0.22 Rb = 3300Ã…, 550Ã… and 220Ã… respectively. These void length scales are comparable to or less than the radii of vesicles formed in the system under conditions of no confinement. A simple thermodynamic model was developed accounting for the balance between increased enthalpy when …

Fabrication, Characterization And Application Of The Novel Bionanomaterials, Lan Yao Jan 2008

Fabrication, Characterization And Application Of The Novel Bionanomaterials, Lan Yao

Open Access Dissertations

This dissertation focuses on developing methods to synthesize novel bionanomaterials, studying their properties and exploring their potential applications. Fabricating semiconducting nanowires is a significant challenge in making nanoscale electronic devices. We propose to use self-assembling biomolecules as templates for the fabrication of nanowires. Here we demonstrate that quantum dots (QDs) could be conjugated to actin filaments, forming long semiconductor filaments. We constructed an optical system and developed the interactive software for fluorescence anisotropy imaging of single QDs and QD-nanowires. The fluorescence anisotropy studies revealed that QD transition dipoles are likely circular (elliptical) dipoles. The fluorescence anisotropy of a single QD …

Chemistry Of Antibiotics From Atlantic Actinomycete And Bacillus Bacteria, Aaron Martin Socha Jan 2008

Chemistry Of Antibiotics From Atlantic Actinomycete And Bacillus Bacteria, Aaron Martin Socha

Open Access Dissertations

The emergence of drug-resistant pathogens requires the use of innovative therapeutic agents. Hospital-acquired (nosocomial) infections represent major health and economic burdens for patients and health care professionals. In the United States over 1 million nosocomial infections are caused by drug-resistant bacteria anually, with associated expenditures ranging from $4 to $30 billion. Methicillin-resistant Staphylococcus aureus (MRSA) commonly shows reduced susceptibility to β-lactam, peptide, macrolide, aminoglycoside, tetracycline, and lincosamide classes of antibiotics. The emergence of vancomycin-resistant enterococci (VRE) is even more alarming since glycopeptide antibiotics were once considered the drugs of last resort. Moreover, community-acquired MRSA infections are spreading out of the …

Design And Evaluation Of Nucleoside Derivatives For Targeted Drug Delivery And Therapeutic Applications, Hitesh Kumar Agarwal Jan 2008

Design And Evaluation Of Nucleoside Derivatives For Targeted Drug Delivery And Therapeutic Applications, Hitesh Kumar Agarwal

Open Access Dissertations

2',3'-Dideoxynucleoside analogs are commonly used as anti-HIV, anti-HBV, and anti-cancer drugs. Despite of their potent activities, there are some major limitations in using 2',3'-dideoxynucleosides as therapeutic agents. The nucleosides have usually poor cellular uptake because of their hydrophilic nature. Some of the nucleoside analogs, such as anti-HIV agents, become ineffective after multiple administrations because of the development of the drug resistance, and therefore they must be administered in combination therapy. It is hard to deliver the nucleoside analogs to a particular tissue for site specific targeting. Furthermore, nucleoside analogs undergo three intracellular phosphorylation steps to become active. The first phosphorylation …

Judicial Hellholes, Lawsuit Climates, And Bad Social Science: Lessons From West Virginia, Elizabeth G. Thornburg Jan 2008

Judicial Hellholes, Lawsuit Climates, And Bad Social Science: Lessons From West Virginia, Elizabeth G. Thornburg

Faculty Journal Articles and Book Chapters

The American Tort Reform Association (ATRA) was founded in 1986 by the American Medical Association and American Council of Engineering Companies, and now has hundreds of corporate members. Every year, ATRA releases a list of Judicial Hellholes: court systems alleged to be unfair to defendants. The name is definitely catchy: the thought of a judicial hellhole invokes images of Kafka, Satan and the Queen of Hearts. No wonder ATRA's hellhole campaign has embedded itself in media vocabulary. And no wonder state courts and state legislatures bend over backwards to get out from under the hellhole label. Similarly, the U.S. Chamber …

Landing Native Fisheries: Indian Reserves And Fishing Rights In British Columbia, 1849-1925, Douglas C. Harris Jan 2008

Landing Native Fisheries: Indian Reserves And Fishing Rights In British Columbia, 1849-1925, Douglas C. Harris

All Faculty Publications

Landing Native Fisheries reveals the contradictions and consequences of an Indian land policy premised on access to fish, on one hand, and a program of fisheries management intended to open the resource to newcomers, on the other. Beginning with the first treaties signed on Vancouver Island between 1850 and 1854, Douglas Harris maps the connections between the colonial land policy and the law governing the fisheries. In so doing, Harris rewrites the history of colonial dispossession in British Columbia, offering a new and nuanced examination of the role of law in the consolidation of power within the colonial state.

The "How" Of The Three Sisters: The Origins Of Agriculture In Mesoamerica And The Human Niche, Amanda J. Landon Jan 2008

The "How" Of The Three Sisters: The Origins Of Agriculture In Mesoamerica And The Human Niche, Amanda J. Landon

Nebraska Anthropologist

The origins of agriculture· in Mesoamerica have long interested archaeologists and antiquarians alike. The approaches used to understand the origins of the three sisters, maize, beans and squash, have changed over time as our understanding of the ecological context and ethnographic influences have changed. In this paper, I examine the history of the study of the origins of agriculture and assess the current evolutionary and ecological approaches to the topic. In Mesoamerica, the three sisters and humans shared a co evolutionary relationship in which humans invited the plants into the human niche and the plants thrived. Over time, the plants …

In Search Of Blood-Stained Earth: A Consideration Of Battlefield Archaeology's Applicability To Pre-Historic Conflict In The Eastern And Central Regions Of North America, Andrew P. Mcfeaters Jan 2008

In Search Of Blood-Stained Earth: A Consideration Of Battlefield Archaeology's Applicability To Pre-Historic Conflict In The Eastern And Central Regions Of North America, Andrew P. Mcfeaters

Nebraska Anthropologist

During the last twenty-four years archaeologists have proven that we are now able to investigate a previously inaccessible part of the archaeological record: the battlefield. These fields of conflict, once inaccessible due to their nature, have become accessible to archaeologists through the use of metal detectors, the global positioning system (GPS), remote sensing, historical documents, maps, photographs (aerial and period), and the geographic information system (GIS), among the traditional methods used in archaeological research, such as surface surveys and excavation. However, battlefield archaeology's current scope is limited to those conflicts recorded by history. Is it possible for battlefield archaeologists to …

Kepler's Method: The Conjoining Of Theoretical And Empirical Science., Marc M. Mezzina

Graduate Theses, Dissertations, and Problem Reports (ETD)

Johannes Kepler was a mathematician that changed the way that science was conceived and practiced in the early seventeenth century. Kepler’s method of scientific inquiry consisted of the joining of the theoretical aspects of astronomy with the solid empirical proof provided by observations. Kepler’s method would lead him to the discovery of his three laws of planetary motion, as well as change the fundamental questions asked by the subject of astronomy. This is a look in the method employed by Kepler throughout his most significant scientific works.

The Effects Of Residual Baylage Leachate On The Germination And Growth Of Orchardgrass (Dactylis Glomerata L.) And Red Clover (Trifolium Pratense L.)., Sheena R. Moore

Graduate Theses, Dissertations, and Problem Reports (ETD)

In early spring, areas of soil directly under baylage, spread for winter consumption by steers, is void of vegetation even after reseeding. This study was conducted to determine if: 1) residual baylage leachate is allelopathic to orchardgrass and red clover, 2) soil microorganisms have an effect on the toxicity of the leachate, and 3) toxicity decreases over time. Petri dishes, as well as potted soil/sand mixtures, were used to test for allelopathy. Leachate reduced seed germination and seedling length as compared to distilled water. There is evidence that soil microorganisms did not affect leachate toxicity. Toxicity of leachate to both …

Delay Discounting In Adolescent Substance Abuse And Juvenile Delinquency: A Comparison Of Measures Of Impulsive Behavior., Eric S. Grady Jan 2008

Delay Discounting In Adolescent Substance Abuse And Juvenile Delinquency: A Comparison Of Measures Of Impulsive Behavior., Eric S. Grady

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recent research in the areas of substance use and juvenile delinquency has revealed that impulsivity is a multi-dimensional construct. Additionally, researchers have expressed the need for more objective, behavioral measures of impulsive behavior. This study was conducted to examine how a delay-discounting procedure, continuous performance test and questionnaire-based measures of impulsivity relate to substance use and delinquent behavior. The sample was comprised of 42 adolescents (35 male) residing in an inpatient treatment facility for alcohol and substance use. The hyperbolic discounting function did not provide a good fit to the delay-discounting data. As such, the area under the curve (AUC) …

Cultural Assimilation, Appropriation And Commercialization: Authenticity In Rap Music, 1997-2004., Jonathan P. Tummons Jan 2008

Cultural Assimilation, Appropriation And Commercialization: Authenticity In Rap Music, 1997-2004., Jonathan P. Tummons

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the changes in authenticity in rap lyrics between 1997 and 2004. Throughout its American history, Black music has expressed the lived experiences, the psychological realities, of Africans in diaspora and has always functioned to help create, negotiate and maintain cultural identity or “Blackness”. Within the last 20 years, rap music has undergone a tremendous amount of commercialization and appropriation by capitalistic culture industries and their largely white consumer base which has resulted in the widespread assimilation of black cultural expression into popular (white) culture. Rap artists increasingly invoke their authenticity as a way of preserving their cultural …

Six Principles For Integrating Non-Governmental Environmental Standards Into Smart Regulation, Stepan Wood, Lynn Johannson Jan 2008

Six Principles For Integrating Non-Governmental Environmental Standards Into Smart Regulation, Stepan Wood, Lynn Johannson

All Faculty Publications

Ontario recently introduced environmental penalties (EPs), the environmental equivalent of speeding tickets. EPs are widely understood as part of a move toward "smarter" environmental regulation. As part of the EPs regime, facilities with an environmental management system aligned with ISO 14001 or Responsible Care qualify for reduced penalties. The Ontario government’s attempt to incorporate voluntary standards - such as ISO 14001 - into its EPs regulations was not very smart, however, because it failed to observe six principles that, in our view, should guide the incorporation of standards into smart regulation. First, do not reinvent the wheel. If an existing …

The Relative Efficacy Of Three Procedures For Reducing Canine Responding., Megan E. Maxwell Jan 2008

The Relative Efficacy Of Three Procedures For Reducing Canine Responding., Megan E. Maxwell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three response reduction procedures commonly employed in applied behavior analysis are extinction, differential-reinforcement-of-other-behavior (DRO) schedules, and time-based schedules of event delivery such as the fixed-time (FT) schedule. Each of these three procedures holds promise for the amelioration of canine behavior problems, yet none has been studied systematically, alone or in comparison with other procedures, with domestic dogs. In this research, the buoy-touching responses of eleven dogs were shaped and maintained using edible reinforcers. Responding then was exposed either to extinction, a fixed or an escalating DRO schedule, or an FT schedule. Extinction reduced responding more rapidly than the escalating DRO …

Fibroblast Growth Factor -19: A Novel Factor That Inhibits Hepatic Fatty Acid Synthesis., Sushant Bhatnagar Jan 2008

Fibroblast Growth Factor -19: A Novel Factor That Inhibits Hepatic Fatty Acid Synthesis., Sushant Bhatnagar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous studies have shown that administration of fibroblast growth factor-19 (FGF-19) reverses diabetes, hepatic steatosis, hyperlipidemia, and adipose accretion in animal models of obesity. To investigate the mechanism for this effect, we determined whether FGF-19 modulated hepatic fatty acid synthesis, a key process controlling glucose tolerance and triacylglycerol accumulation in liver, blood, and adipose tissue. Incubating primary hepatocyte cultures with recombinant FGF-19 suppressed the ability of insulin to stimulate fatty acid synthesis. This effect was associated with a reduction in the expression of lipogenic enzymes. FGF-19 also suppressed the insulin-induced expression of sterol regulatory element-binding protein-1c (SREBP-1c), a key transcriptional …

User Fees In Local Finance: Performance And Potential In Czech And Slovak Republics, Phillip J. Bryson Jan 2008

User Fees In Local Finance: Performance And Potential In Czech And Slovak Republics, Phillip J. Bryson

Faculty Publications

The Czech Republic and Slovakia, like other transition countries in Central and Eastern Europe, have given significant lip service to fiscal decentralization and engaged in public administration reforms. But the subnational governments of their public finance systems still lack relative autonomy, which could be addressed partly through developing independent revenue sources for their municipalities and regions. Currently, such independent revenue sources include the proceeds of a strictly nominal property tax as well as those of a small set of local user fees and taxes designed and approved by the central governments. Together they represent only about 5 percent of total …

A Genetic Variant Of The Adaptor Protein, Afap-110, Efficiently Activates C-Src Resulting In Podosome Formation., David A. Clump

Graduate Theses, Dissertations, and Problem Reports (ETD)

The actin filament associated protein of 110 kDA (AFAP-110) is a well-characterized protein composed of amino-terminal binding motifs that function upstream of a carboxy-terminal actin binding domain. In vitro studies demonstrate that the amino-terminal pleckstrin homology 1 (PH1) domain interacts with activated PKCα, relaying signals that activate Src family kinases via SH3 and SH2 binding. Serving as an adaptor protein, AFAP-110 relays signals that result in the assembly of motility structures. These findings could be of physiological as well pathological significance as AFAP-110 colocalizes with SFKs in the developing brain as well as in the glial-derived tumor, glioblastoma multiforme.
