Improving Regulation Through Incremental Adjustment, Robert L. Glicksman, Sidney A. Shapiro
Improving Regulation Through Incremental Adjustment, Robert L. Glicksman, Sidney A. Shapiro
GW Law Faculty Publications & Other Works
Claiming that existing regulation is excessive and irrational, regulatory critics have successfully convinced Congress and the White House to implement a plethora of procedural requirements to analyze a proposed regulation before it is promulgated. In our book, Risk Regulation at Risk: Restoring A Pragmatic Approach (2003), we argued that the previous initiatives address the possibility of regulatory failure on the wrong end of the regulatory policy implementation process. We suggested that one way of improving regulation would be to rely on incremental adjustments in regulation on the back end of the regulatory process. This article addresses in more detail the …
Evaluation Of Human Papillomavirus And Chlymdia Tachomatis Infections In The Irish Female Population: Determination Of Prevalence In Adults U Ndergoing Opportunistic Cervical Screening, Helen Keegan
Doctoral
Human papillomaviruses and Chlamydia trachomatis are two of the most common sexually transmitted infections worldwide. They can be detected using urine, swab and cervical scrapings from the anogenital region. Liquid-based cervical cytology is fast becoming the method of choice for the preparation of cervical smears, with the major advantage of extra cellular material from which nucleic acids can be extracted and molecular tests performed. In this project, nucleic acid based methods for the detection of HPV and C. trachomatis and the quantitation and typing of HPV from PreservCyt cervical material were established and applied in an epidemiological study of the …

Articles
Background: Acyl-CoA thioesterases are enzymes that hydrolyze acyl-CoAs to the free fatty acid and coenzyme A (CoASH). These enzymes have been identified in several cellular compartments and are thought to regulate intracellular levels of acyl-CoAs, free fatty acids and CoASH. However, to date no patients deficient in acyl-CoA thioesterases have been identified. Design: Acyl-CoA thioesterase activity was measured in human skin fibroblasts. Western blot analysis was used to determine Type-II acyl-CoA thioesterase protein levels in patients. Results: Activity was found in human fibroblasts with all saturated acyl-CoAs from C4:0- to C18:0-CoA, with highest activity detected with lauroyl-CoA and myristoyl-CoA (C12:0 …
The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna
The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna
Doctoral
Peroxidases and its effects on plants were analysed. Peroxidases are involved in many physiological processes in plants, involving responses to biotic and abiotic stresses and the biosynthesis of lignin. Liglin is a polymer responsible for rendering the plant stronger and more rigid and also making the cell walls hydrophobic. Peroxidases are involved in the polymerization of the precursors of lignin. They are also involved in the scavenging of Reactive Oxygen Species (ROS), which are partially reduced forms of atmospheric oxygen, highly reactive, and capable of causing oxidative damage to the cell. Peroxidases can be a source of hydrogen peroxide (H2O2) …

Glioblastoma (GBM) is a type of intracranial brain tumor, for which there is no cure. In spite of advances in surgery, chemotherapy and radiotherapy, patients die within a year of diagnosis. Therefore, there is a critical need to develop novel therapeutic approaches for this disease. Gene therapy, which is the use of genes or other nucleic acids as drugs, is a powerful new treatment strategy which can be developed to treat GBM. Several treatment modalities are amenable for gene therapy implementation, e.g. conditional cytotoxic approaches, targeted delivery of toxins into the tumor mass, immune stimulatory strategies, and these will all …
Biomarkers For Placental Abnormality, Cathal Mccarthy
Biomarkers For Placental Abnormality, Cathal Mccarthy
Doctoral
Obstetrical complications including recurrent miscarriage, pre-eclampsia and intrauterine growth restriction (IUGR) affect 1%-5% of pregnant women (Younis and Samueloff 2003). Dysfunctional trophoblasts, impaired development of spiral arteries, imbalance in systems controlling the dilation and contraction of spiral arteries, placental fibrin clots and intervillous thrombosis are all possible factors that can result in an insufficient placental circulation. The combination of the hypercoagulable state of pregnancy and presence of genetic thrombophilic markets has the potential to induce placental thrombosis and cause placental insufficiency with subsequent obstetrical complications. The initial part of the research work involved examining the relationship between four common genetic …
Optimization Of An Acrylamides-Based Photopolymer For Reflection Holographic Recording, Raghavendra Jallapuram
Optimization Of An Acrylamides-Based Photopolymer For Reflection Holographic Recording, Raghavendra Jallapuram
Doctoral
Photopolymers have been the subject of special attention in the last two decades. The advantage of being self-developing makes them a practical alternative to silver halide photographic emulsions in holographic interferometry applications. This thesis is aimed at understanding diffusion properties and optimization of an acrylamide-based green sensitized photopolymer material for reflection holographic recording. The composition of the photopolymer includes a green sensitive dye (erythrosine B), acrylamide (monomer), electron donor (triethanolamine) a cross linking monomer (NN’methylenebisacrylamide) and a binder (polyvinyl alcohol). On illumination with light of the appropriate wavelength the dye absorbs a photon and enters into an excited state. The …

Real-Time Reverse Transcription Pcr For Detection And Quantitative Analysis Of Equine Influenza Virus, Michelle Quinlivan, Eugene Dempsey, Fergus Ryan, Sean Atkins, Ann Cullinane
Articles
Equine influenza is a cause of epizootic respiratory disease of the equine. The detection of equine influenza virus using real-time Light Cycler reverse transcription (RT)-PCR technology was evaluated over two influenza seasons with the analysis of 171 samples submitted for viral respiratory disease. Increased sensitivity was found in overall viral detection with this system compared to Directigen Flu A and virus isolation, which were 40% and 23%, respectively, that of the RT-PCR. The assay was also evaluated as a viable replacement for the more traditional methods of quantifying equine influenza virus, 50% egg infectious dose and 50% tissue culture infectious …

Synthesis And Characterization Of Nickel(Ii) Coordination Complexes With Hydrotrispyrazolylborato And Dithiobenzoato Ligands, Brian Matthew Enggano
Honors Theses
The objective of this project is to prepare Ni(II) coordinate complexes that represent hydrogenase model active sites. The synthetic analog approach provides an effective means to study redox behavior of nickel. Six Ni(II) complexes with the hydrotris(3,5- dimethylpyrazolyl)borate ligand and varying forms of the dithiobenzoate ligand were synthesized through ligand substitution using a novel procedure in the laboratory. Infrared spectrophotometry and elemental analysis show that the synthesis of the complexes was successful. Each Ni(II) complex had the characteristic B-H (boronhydrogen) stretch representative of the hydrotris(3,5-dimethylpyrazolyl)borate ligand at approximately 2500 cm’’ as well as the Ar-H and C=C stretches at 3100-3000 …

Engineering Genetic Networks To Measure Real Time Repression By Λ Cro In Vivo, Zachary Louis Leblanc
Honors Theses
The field of systems biology seeks to engineer systems in order to explore specific dynamic properties as they act in vivo. Cellular activities have been proven to be regulated by a range of DNA binding proteins that bind to specific sequences that activate or repress transcription. Certain phage and bacterial repressor proteins were among the first of these DNA binding proteins to be characterized structurally and functionally. The demand for study of key steps in regulation of protein expression, folding, and repression has created multiple studies into systems of varying complexity. The data in this report explores the lambda system, …

Spectroscopic Studies Of Site 3 Mutants Of Calmodulin, Shakirat Omolara Oyetunji
Honors Theses
Calmodulin is the quintessential member of the EF-hand family of calcium binding proteins. Two mutants of the C-domain of Calmodulin were created as a series of proteins that can be used as model 1-site calcium binding systems, terminal glutamate in Site 3 was mutated to either glutamine or aspartate, mutations were expected to abrogate binding in the mutated site such that only Site 4 is functional. There was minimal overall perturbation to the folding and stability of the apo-state. Calcium binding properties of these mutant proteins were investigated by 1) direct titrations with calcium were performed under equilibrium conditions monitored …

Size Exclusion Chromatography: Estimation Of Protein Shape, Gregg Oyemachi Anazia
Honors Theses
Cadherin is a cell adhesion protein that is significant in tissue formation. The protein is comprised of an extracellular region, a transmembrane segment and a cytoplasmic domain. The extracellular region contains five independently folded Pbarrel domains. They communicate with one another through calcium ions that bind at the interface between each domain. Our laboratory is interested in characterizing the interactions that the extracellular domains participate in. As a part of this overall goal, analytical techniques must be developed to assess the size of the constmcts. This is important for basic characterization of the recombinant proteins. Determining the change in size …
Lessons For Competition Policy From The Vitamins Cartel, William E. Kovacic
Lessons For Competition Policy From The Vitamins Cartel, William E. Kovacic
GW Law Faculty Publications & Other Works
Mergers have the potential for negative social welfare consequences from increased likelihood or effectiveness of future collusion. This raises the question of whether there are meaningful thresholds for the post-merger industry that should trigger significant scrutiny by the Department of Justice or Federal Trade Commission. This paper provides empirical analysis relevant to this question. The data does not come from an industry in which there were mergers, but instead from an industry in which explicit collusion was admittedly rampant in the 1990's, the Vitamins Industry. Different vitamin products are produced by different numbers of firms, and for different vitamin products, …
