A Genome-Wide Over-Expression Screen Identifies Genes Involved In Phagocytosis In The Human Protozoan Parasite, Entamoeba Histolytica, Ada V. King, Brenda H. Welter, Amrita B. Koushik, Lindsay N. Gordon, Lesly A. Temesvari

Publications

Functional genomics and forward genetics seek to assign function to all known genes in a genome. Entamoeba histolytica is a protozoan parasite for which forward genetics approaches have not been extensively applied. It is the causative agent of amoebic dysentery and liver abscess, and infection is prevalent in developing countries that cannot prevent its fecal-oral spread. It is responsible for considerable global morbidity and mortality. Given that the E. histolytica genome has been sequenced, it should be possible to apply genomic approaches to discover gene function. We used a genome-wide over-expression screen to uncover genes regulating an important virulence function …

Sensitivity Anaylsis And Detectability For Magnetic Resonance Elastography, Catherine White

All Dissertations

This thesis is for a sensitivity analysis of magnetic resonance elastography, a hybrid imaging technique used in early-stage cancer screening. To quantitatively analyze the sensitivity, we introduce a notion of detectability, which is dened as a relative amplitude
drop in a small sti tumor region. This analysis is accomplished in both the full elastic and viscoelastic models and compared with that of the simpler scalar model which is frequently used in the actual application.
Some of the highlights are 1) a useful formula for detectability in terms of physical parameters, which will help the design of experiments; 2) the discrepancy …

Investigating The Role Of Mechanosensitive Ion Channels In Urothelial Cell Pressure Mechanotransduction, Shawn Olsen

All Dissertations

Overactive bladder (OAB) is a bladder disorder that is characterized by bladder storage symptoms of urgency with or without urge incontinence, frequency, nocturia, and, as of 2003, affected approximately 16.5% of adults in the United States with an annual treatment cost of over $65 billion. While therapies are available to mitigate the symptoms of OAB, there are no treatments for the cause of OAB, due to the lack of understanding of the etiology of the disorder. Recent research has provided evidence that the bladder urothelium is not just a passive barrier, but is also sensitive to various chemical and mechanical …

Laboratory Characterization And Theoretical Analysis Of Contaminant Mass Transfer, Xiaoling Liu

All Dissertations

Chlorinated volatile organic compounds (CVOCs) in fractured, low permeability material can be a long-term source of groundwater contaminants and they are among the most difficult remediation challenges. Thermal methods are a possible remediation option, where heat is used to boil water and the volatile compounds are stripped out by partitioning into the resulting water vapor. Theoretical analysis indicates that only a small fraction of pore water removal may lead to a significant geometric reduction in the dissolved concentration [(Udell(, 1998]. Previous modeling studies [(Falta and Murdoch(, 2011; (Pruess(, 1983] suggest that a lower permeability limit exists for effective mass transfer …

Camera Creatures: Rhetorics Of Light And Emerging Media, Anthony Collamati

All Dissertations

Camera Creatures addresses the new media landscape in which cameras, in most situations, outnumber pens. The dissertation argues that despite the accessibility and power of imagemaking devices, there persists in the humanities and social sciences a hesitation to engage the possibilities for composing with optical media. A number of factors contributing to this trend are addressed, including the preference for image analysis over imagemaking practices, persistent assumptions of the camera's mechanical objectivity, and a tendency to teach visual invention as collage. As a counter-measure, a proposal is made for investment in the mediation of light, or 'photonic rhetorics.' To explore …

The Role Of Acetyl-Coa Carboxylase In The Survival Of Trypanosoma Brucei During Infection, Ciara Mcknight

All Theses

This master's thesis focuses on how disruption of fatty acid metabolism affects both host adaptation and immune evasion in the deadly eukaryotic parasite, Trypanosoma brucei. In Chapter 1, I review the current literature on African trypanosomiasis, fatty acid synthesis, immune evasion, and lipid metabolism. In Chapter 2, I investigate how disruption of the fatty acid synthesis pathway affects the parasite's ability to evade the host immune defenses. When T. brucei acetyl-CoA carboxylase (TbACC) is knocked down by RNA interference (RNAi), fluid phase and receptor mediated endocytosis pathways are greatly affected, suggesting that fatty acid synthesis is necessary for both endocytic …

Factors Affecting The Production Of Concentrated Blue Cheese Flavorings, Jason Raines

All Theses

The effects of media type and culture selection on the aroma profile of Blue cheese flavorings produced using submerged culture fermentation were studied. Fermentations were carried out for 16 hours then compared using sensory analysis and GC/MS SPME. The differences between samples were minimal. Samples produced with adjunct media were found to have higher concentrations of methyl ketones and more &ldquo'creamy'&rdquo aroma character than samples produced from standard media. Higher levels of free fatty acids were found in standard media samples. Adjunct cultures appear to enhance the &ldquo'creamy'&rdquo character of Blue cheese flavorings.
Near-critical and supercritical carbon dioxide were used …

Functional Characterization Of A Jacalin-Like Lectin Domain-Containing Protein In Arabidopsis Thaliana, Shane Reighard

All Theses

Jacalin-related lectins (JRLs) are proteins that bind carbohydrates. Functionally, JRLs are thought to be involved in a diverse array of functions including biotic stress defense, intracellular storage, abiotic stress response, and plant development. Recent Arabidopsis thaliana microarray data indicate that a Jacalin-like domain-containing protein (JLL1) exhibits highly root specific expression. Previous transcriptomic and proteomic studies indicate that JLL1 may have a dual role in planta as a biotic stress defense protein and in plant development. In order to better understand the physiological function of JLL1 in Arabidopsis, several different analyses were conducted examining its regulatory sequences, spatial expression, responsiveness to …

Evaluation Of Dichloromethane As An Electron Donor For Reductive Dechlorination Of Tetrachloroethene To Ethene, Yogendra Kanitkar

All Theses

Tetrachloroethene (PCE) and trichloroethene (TCE) are the predominant contaminants at hazardous waste sites in the United States. Although less prevalent, dichloromethane (DCM) is also found at a number of sites. EPA classifies PCE and DCM as likely to be carcinogenic in humans by all routes of exposure, while TCE is classified as carcinogenic to humans by all routes. At some sites, releases of PCE, TCE and DCM comingle in the groundwater. Field evidence from one such site in California suggests that DCM is used as the electron donor for reductive dechlorination of TCE. Nevertheless, definitive evidence that DCM can serve …

The Influence Of Dissolved Organic Carbon And Surface Chemistry On The Toxicity Of Silver Nanoparticles In Daphnia Magna, Kim Newton

All Theses

Silver nanoparticles (AgNPs) are by far the most extensively used nanomaterial in general consumer products. Concurrent with this use is the major concern regarding the toxicity of AgNPs to aquatic organisms. The most persistent question regarding the toxicity of AgNPs is whether this toxicity is due to the nanoparticles (NPs) themselves or the ions they release. Two primary factors influencing the aquatic toxicity of AgNPs are the surface coating, which presumably controls the release of Ag+, and the dissolved organic carbon (DOC) of the media, which serves as a source for ligands to bind the Ag+ and reduce bioavailability to …

The Relationship Between Motivations For Physical Activity And Self-Esteem Of College Women, Emily Turke

All Theses

Physical activity can have a positive impact on several aspects of mental health, including self-esteem. Positive mental health effects of physical activity may be related to increased skill competency and social interaction (Paluska & Schwenk, 2000). Research indicates that self-esteem is also increased by participation in physical activity. Specifically, girls who participate in physical activity have higher self-esteem than girls who do not participate (Wilson & Rodgers, 2002; Schmalz, Deane, Birch, Davidson, 2007). Self-esteem that emerges from physical activity is an important factor in the health and wellbeing of college women. Social, emotional, academic and physical aspects of a young …

The Effect Of Granular Activated Carbon Pretreatment And Sand Pretreatment On Microfiltration Of Greywater, David Christopher

All Theses

Around the world, water scarcity is driving people to practice water reuse. One form of water reuse is the recycling of greywater, which is household wastewater excluding toilet waste. With adequate treatment, greywater may be recycled onsite for applications that do not require potable water, such as irrigation or toilet flushing. Membrane filtration (including microfiltration (MF)) is one option for greywater treatment. The small footprint, modular nature, and predictable performance of MF make it an attractive option. However, direct MF of greywater can lead to rapid membrane fouling. This thesis investigated two possible pretreatments for reducing membrane fouling and improving …

The Social Psychology Of Evil: A Look At Abu Ghraib, Kristin Richardson

All Theses

In the spring of 2004, the military police assigned to guard the Abu Ghraib prison in Baghdad, Iraq found themselves at the center of numerous investigations regarding the abuse, torture, rape, and murder of detainees in United States custody. Their behavior was influenced and encouraged by U.S. officials, including President George W. Bush and Secretary of Defense Donald Rumsfeld. The Bush administration effectively created a reality for the military police that fostered increasingly violent and aggressive tendencies beyond what is expected or allowed in similar circumstances. Existing literature and conclusions from previous studies support the claim that social and situational …
