Outcome Variables Of Childhood Sexual Abuse As Potential Risk Factors For Sexual Revictimization In Adulthood, Christine Renee Bowles

Theses and Dissertations

Childhood sexual abuse is a large problem, with research estimates indicating that between 16-25% of women have experienced sexual abuse at some point during their childhood (Dube et al., 2005; Gorey & Leslie, 1997). Even more alarming is the data that suggests that women who have experienced childhood sexual abuse are between 2 to 11 times more likely to experience sexual assault as an adult than individuals with no past history of abuse (Messman-Moore & Long, 2003). To help understand the complex and varied outcomes associated with childhood sexual abuse, Finkelhor and Browne (1985) developed a model conceptualizing the four …

Biomaterial Testing Methodology For Long-Term In Vivo Applications: Silicon Carbide Corrosion Resistance, Biocompatibility And Hemocompatibility, Maysam Nezafati

USF Tampa Graduate Theses and Dissertations

Biomedical devices that function in-vivo offer a tremendous promise to improve the quality of life for many who suffer from disease and trauma. The most important consideration for these devices is that they interact with the physiological environment as designed without initiating a deleterious inflammatory response. ISO 10993 outlines the current international guideline for investigating the biocompatibility of such devices. Numerous groups report the use of ISO 10993 as the basis for their experimental evaluation of candidate materials for neuroprosthetics, as well as other biomedical devices, however most of these reports fail to completely comply with the standard. This leads …

Soft Shape-Memory Polymers As A Platform For Biomedical Applications, Amir Hossein Torbati

Dissertations - ALL

The overall objective of this work was to expand on the previous efforts carried out by other researchers to develop series of "smart" or stimulus-responsive shape-memory polymers for biomaterials applications. For this purpose, novel shape-memory polymers were fabricated and their macrostructure and microstructure were studied to understand their effects on overall shape-memory characteristics and mechanical properties of these materials. The advent of shape-memory polymers has significantly influenced the development and rapid growth of various functional polymers. Shape-memory polymers are used where the dynamic functions of polymers under an applied stimulus are required, and they find applications as catheters, sutures, drug …

Predicting Alcohol Consumption In Adolescent Rhesus Macaques (Macaca Mulatta), Andrea Nichole Sorenson

Theses and Dissertations

Numerous studies show that a low level of response to the intoxicating effects of alcohol is considered a risk factor for future alcoholism. However, assessing this sensitivity usually requires administering a controlled dose of alcohol, which has a number of inherent problems. Early observations in our lab suggest that the response to anesthetics that show cross tolerance with alcohol, like ketamine, are blunted in nonhuman primates at risk for high alcohol intake, and may be a viable measure of future alcohol consumption. This study was designed to test potential predictors of future alcohol consumption using the change in ketamine across …

Naïve Hosts Of Avian Brood Parasites Accept Foreign Eggs, Whereas Older Hosts Fine-Tune Foreign Egg Discrimination During Laying, Csaba Moskát, Miklós Bán, Mark E. Hauber

Publications and Research

Background: Many potential hosts of social parasites recognize and reject foreign intruders, and reduce or altogether escape the negative impacts of parasitism. The ontogenetic basis of whether and how avian hosts recognize their own and the brood parasitic eggs remains unclear. By repeatedly parasitizing the same hosts with a consistent parasitic egg type, and contrasting the responses of naïve and older breeders, we studied ontogenetic plasticity in the rejection of foreign eggs by the great reed warbler (Acrocephalus arundinaceus), a host species of the common cuckoo (Cuculus canorus).

Results: In response to experimental parasitism before the …

Paradise Always Already Lost: Myth, Memory, And Matter In English Literature, Elizabeth Stuart Angello

USF Tampa Graduate Theses and Dissertations

This dissertation follows a collection of agentive objects around and through the networks of humans and nonhumans in four disparate works of English literature: the Anglo-Saxon poem The Dream of the Rood, William Shakespeare's narrative poem The Rape of Lucrece, Thomas Hardy's novel The Woodlanders, and Philip Pullman's trilogy His Dark Materials. Applying the emergent discourses of object-oriented analyses, I posit the need for a critique that considers literary objects not as textual versions of real-world objects but as constructs of human imagination. What happens when we treat nonhuman or inanimate objects in literature as full …

Study Of Process Control Strategies For Biological Nutrient Removal In An Oxidation Ditch, Leslie Ann Knapp

USF Tampa Graduate Theses and Dissertations

Advanced wastewater treatment plants must meet permit requirements for organics, solids, nutrients and indicator bacteria, while striving to do so in a cost effective manner. This requires meeting day-to-day fluctuations in climate, influent flows and pollutant loads as well as equipment availability with appropriate and effective process control measures. A study was carried out to assess performance and process control strategies at the Falkenburg Road Advanced Wastewater Treatment Plant in Hillsborough County, Florida.

Three main areas for control of the wastewater treatment process are aeration, return and waste sludge flows, and addition of chemicals. The Falkenburg AWWTP uses oxidation ditches …

The Interrelationship Of Brca1 185delag, Interleukin-1Β, And Ovarian Oncogenesis, Kamisha Woolery

USF Tampa Graduate Theses and Dissertations

While the etiology of ovarian cancer (OC) is not completely understood, evidence suggests that chronic inflammation may promote malignant transformation. However, familial history remains the strongest risk factor for developing OC and is associated with germline BRCA1 mutations, such as the 185delAG mutation. Normal human ovarian surface epithelial cells expressing the 185delAG mutant, BRAT, exhibit molecular and pathological changes that may contribute to OC oncogenesis. In the current study, I sought to determine whether BRAT could promote an inflammatory phenotype by investigating BRAT's impact on the expression of the proinflammatory cytokine, Interleukin-1β (IL-1β). Using a culture model system of normal …

Effective Permeability Upscaling From Heterogenous To Homogenous Porous Media, Mehmet Cicek, Deepak Devegowda, Faruk Civan, Richard Sigal

5th International Conference on Porous Media and Their Applications in Science, Engineering and Industry

An effective method to upscale permeability is presented to represent a heterogeneous reservoir with homogeneous permeability and porosity values. As a result, there is no need to deal with dual-porosity or dual-permeability models in reservoir simulations. Thus, the required CPU time for reservoir production and flow simulations is reduced significantly.

Role Of Lysosomes In Silica-Induced Inflammasome Activation And Inflammation In Absence Of Macro, Rupa Biswas, Raymond F. Hamilton, Andrij Holian

Public and Community Health Sciences Faculty Publications

MARCO is the predominant scavenger receptor for recognition and binding of silica particles by alveolar macrophages (AM). Previously, it was shown that mice null for MARCO have a greater inflammatory response to silica, but the mechanism was not described. The aim of this study was to determine the relationship between MARCO and NLRP3 inflammasome activity. Silica increased NLRP3 inflammasome activation and release of the proinflammatory cytokine, IL-1b, to a greater extent in MARCO^-/- AM compared to wild type (WT) AM. Furthermore, in MARCO^-/- AM there was greater cathepsin B release from phagolysosomes, Caspase-1 activation, and acid sphingomyelinase activity …

Ex Uno Plures: Clonal Reinforcement Drives Evolution Of A Simple Microbial Community, Margie A. Kinnersley, Jared Wenger, Evgueny Kroll, Julian Adams, Gavin Sherlock, Frank Rosenzweig

Biological Sciences Faculty Publications

A major goal of genetics is to define the relationship between phenotype and genotype, while a major goal of ecology is to identify the rules that govern community assembly. Achieving these goals by analyzing natural systems can be difficult, as selective pressures create dynamic fitness landscapes that vary in both space and time. Laboratory experimental evolution offers the benefit of controlling variables that shape fitness landscapes, helping to achieve both goals. We previously showed that a clonal population of E. coli experimentally evolved under continuous glucose limitation gives rise to a genetically diverse community consisting of one clone, CV103, that …

Entropy, Information, Landauer’S Limit And Moore’S Law, Paul Tobin, Jonathan Blackledge

Conference papers

In this paper we explore the link between information and entropy by considering the infamous Maxwell demon thought experiment. A non-rigorous mathematical solution by Le´o Szil´ard established this link for the first time, as did Claude Shannon nineteen years later. In 1961, Rolf Landauer’s mathematical solution resulted in the Landauer limit, which is still being hotly debated, but here we discuss the implication of this limit on Moore’s law and future growth in computing power. A workaround the limit is proposed using an Analogue Artificial Neural Network (AANN). Here, we mimic the action of a human brain synapse formed from …

Deep Two-Photon Microscopic Imaging Through Brain Tissue Using The Second Singlet State From Fluorescent Agent Chlorophyll Α In Spinach Leaf, Lingyan Shi, Adrián Rodríguez-Contreras, Yury Budansky, Yang Pu, Thien An Nguyen, Robert R. Alfano

Publications and Research

Abstract. Two-photon (2P) excitation of the second singlet (S2) state was studied to achieve deep optical microscopic imaging in brain tissue when both the excitation (800 nm) and emission (685 nm) wavelengths lie in the “tissue optical window” (650 to 950 nm). S2 state technique was used to investigate chlorophyll α (Chl α) fluorescence inside a spinach leaf under a thick layer of freshly sliced rat brain tissue in combination with 2P microscopic imaging. Strong emission at the peak wavelength of 685 nm under the 2P S2 state of Chl α enabled the imaging depth up to 450 μm through …

High Throughput Screening Identifies Modulators Of Histone Deacetylase Inhibitors, Ann-Christin Gaupel, Thomas Begley, Martin Tenniswood

Biological Sciences Faculty Scholarship

Background

Previous studies from our laboratory and others have demonstrated that in addition to altering chromatin acetylation and conformation, histone deacetylase inhibitors (HDACi) disrupt the acetylation status of numerous transcription factors and other proteins. A whole genome yeast deletion library screen was used to identify components of the transcriptional apparatus that modulate the sensitivity to the hydroxamic acid-based HDACi, CG-1521.

Results

Screening 4852 haploid Saccharomyces cerevisiae deletion strains for sensitivity to CG-1521 identifies 407 sensitive and 80 resistant strains. Gene ontology (GO) enrichment analysis shows that strains sensitive to CG-1521 are highly enriched in processes regulating chromatin remodeling and transcription …

You Can’T Teach Speed: Sprinters Falsify The Deliberate Practice Model Of Expertise, Michael P. Lombardo, Robert O. Deaner

Open Access Publishing Support Funded Articles

Many scientists agree that expertise requires both innate talent and proper training. Nevertheless, the highly influential deliberate practice model (DPM) of expertise holds that talent does not exist or makes a negligible contribution to performance. It predicts that initial performance will be unrelated to achieving expertise and that 10 years of deliberate practice is necessary.We tested these predictions in the domain of sprinting. In Studies 1 and 2 we reviewed biographies of 15 Olympic champions and the 20 fastest American men in U.S. history. In all documented cases, sprinters were exceptional prior to initiating training, and most reached world class …

Phosphoinositides: Minor Lipids Make A Major Impact On Photoreceptor Cell Functions, Raju V. S. Rajala, Ammaji Rajala, Andrew J. Morris, Robert E. Anderson

Internal Medicine Faculty Publications

Activation of the phosphoinositide (PI) cycle generates the second messengers that control various aspects of cellular signaling. We have previously shown that two PI cycle enzymes, type II phosphatidylinositol 5-phosphate 4-kinase (PIPK IIα) and phosphoinositide 3-kinase (PI3K), are activated through light stimulation. In our earlier studies, we measured enzyme activities, instead of directly measuring the products, due to lack of sensitive analytical techniques. Cells have very low levels of PIs, compared to other lipids, so special techniques and sensitive analytical instruments are necessary for their identification and quantification. There are also other considerations, such as different responses in different cell …

Towards An Automated System For Evaluation Of Visualizations, Douglas Taggart

Theses and Dissertations

The Information Visualization field focuses on the visualization of abstract data, and with the growing interest in big data analysis, the need for analyzing complex datasets is nowadays highly relevant. With the growing amount and diversity of these datasets new and exciting ways to visualize them are being developed. However, being able to thoroughly test and evaluate the effectiveness of these new visualization techniques is an arduous manual process. Moreover, different researchers hold different opinions on how to thoroughly evaluate a new visualization method. A step towards automating the process of evaluation of visualizations, called the Framework for the Evaluation …
