Regulation Of The Tumor Suppresser P53 And Survivin By Ras And Ral Gtpases:Implications For Malignant Transformation, Awet G. Tecleab

USF Tampa Graduate Theses and Dissertations

Abstract

Although the critical role of the small GTPases Ras and Ral in oncogenesis has been well documented, much remains to be investigated about the molecular mechanism by which these GTPases regulate malignant transformation. The work under this thesis made two major contributions to this field. The first is the discovery that K-Ras, RalA and/or RalB are required for the maintenance of the high levels of the anti-apoptotic protein survivin in some human cancer cells, and the second is the demonstration that down regulation of K-Ras, RalA and/or RalB, but not Raf-1 or Akt1/2, stabilizes the tumor suppressor p53 and …

"When You Tell Them, Your Secret Is Out There": Experiences Of Sexuality And Intimacy Among Hiv Positive Black Women, Mackenzie Rae Tewell

USF Tampa Graduate Theses and Dissertations

HIV/AIDS infections disproportionately impact African Americans within the United States. In 2010, black Americans made up 12 percent of the United States population, yet accounted for 44 percent of new HIV/AIDS infections (Kaiser Family Foundation 2013). The majority of black women (85 percent) are infected with the virus through heterosexual contact, meaning it is critical examine their sexual lives in order to gain insight into this infection within this population (CDC 2011b). Through semi-structured interviews at a Tampa, Florida AIDS service organization, this study presents the experiences of sexuality and intimacy among HIV positive black women. Results demonstrate that HIV …

Eco-Epidemiology Of Eastern Equine Encephalitis Virus, Patrick Vander Kelen

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Eastern Equine Encephalitis virus (EEEV) is an alphavirus with high pathogenicity in both humans and horses. Florida continues to have the highest occurrence of human cases in the USA, with four fatalities recorded in 2010. Unlike other states, Florida supports year-round EEEV transmission. This research uses Geographic Information Science (GIS) to examine spatial patterns of documented sentinel seroconversions and horse cases in order to understand the relationships between habitat and transmission intensity of EEEV in Florida. Sentinel sites were categorized as enzootic, periodically enzootic, and negative based on the amount of chicken seroconversions to EEEV. Sentinel sites were analyzed …

A Critical Ethnography Of Globalization In Lesotho, Africa: Syndemic Water Insecurity And The Micro-Politics Of Participation, Cassandra Lin Workman

USF Tampa Graduate Theses and Dissertations

In spite of decades-long development programs, Lesotho faces an ongoing problem of water insecurity with far- reaching individual and social impacts. The purpose of this research was to understand how women in Lesotho are impacted by the synergistic epidemics, or syndemics, of water insecurity and HIV/AIDS and how they respond to these forces. Little has been done to address how water insecurity, defined in terms of both sufficient amount and quality of water, catalyzes the syndemic impact on the people of Lesotho. Access to safe and reliable sources of water is crucial for all individuals, particularly those who have been …

Exploring Potential Risk Factors Of Fetal Origins Of Diabetes: Maternal Stressors During Pregnancy And Birth Outcomes Among Women In A Hospital In The Municipality Of Caguas, Puerto Rico, Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Puerto Rico has the highest prevalence of type 2 diabetes, low birth-weight, and the second highest prevalence of preterm-birth in all the U.S. and its non-incorporated territories. These conditions are related. Birth-weight at both ends of the spectrum and preterm-birth are associated with an increased risk for developing type 2 diabetes and immune-inflammatory dysregulations. Maternal psychosocial stressors during pregnancy have also been recognized as potential risk factors for type 2 diabetes, and have been consistently associated with preterm-birth and low birth-weight across populations. Current evidence points toward epigenetic fetal metabolic-programming as the mechanism that underlies the increased risk for the …

The Effect Of Drug Resistance On Plasmodium Falciparum Transmission And Gametocyte Development, Samantha Olivia Aylor

USF Tampa Graduate Theses and Dissertations

In order to reduce malaria prevalence worldwide, a better understanding of parasite transmission and the effect of drug resistance is needed. The effect of drug resistance on malaria transmission has been examined for some drugs, but not for mitochondrial inhibitors such as atovaquone and the current basis of malaria therapy, artemisinin. Therefore, the goal of this study was to produce gametocytes, the life cycle stage that transmits from mosquito to human, in several different drug resistant patient isolates as well as to determine the effect of drug resistance on gametocyte development and transmission. Previous studies have shown that the mutation …

Knowledge And Practice Of Reproductive Health Among Mothers And Their Impact On Fetal Birth Outcomes: A Case Of Eritrea, Winta Negusse Araya

USF Tampa Graduate Theses and Dissertations

Maternal mortality is a huge concern globally leading to more than a quarter of a million deaths every year. Similarly, an estimated 4 million neonates die every year worldwide, contributing to the majority of deaths of under-5 children. The majority of these deaths take place in under-developed countries, and specifically, in the sub-Saharan Africa region. It is evidenced that maternal ill-health and death contribute to the majority of child deaths. Reducing the death of children under 5 years by two thirds and also improving maternal health/reducing maternal death by three quarters between the years 1990 and 2015 are two of …

An Evaluation Of Check-In/Check-Out With Accountability Tracking For At-Risk Students In A High-Need Elementary School, Ashley Lauren Barber

USF Tampa Graduate Theses and Dissertations

A multi-tiered system of supports offers a comprehensive model for the prevention of academic and behavior problems in schools. To date, research has emphasized the impact of universal and intensive interventions. However, the need for research on secondary or targeted group interventions (Tier 2) for those students who do not respond to the universal level of support is growing. This study evaluated CICO, a Tier 2 intervention, in improving student behavior when it is used with three elementary students from a high-need population and in conjunction with student accountability tracking, designed to promote parental involvement. Functional assessments indicated that all …

An Evaluation Of Staff Reactivity Following Performance Feedback And Self-Monitoring Procedures In A Group Home Setting, Samantha Lynn Fuesy

USF Tampa Graduate Theses and Dissertations

Research has investigated staff management procedures that produce treatment adherence and maintenance over time. Treatment integrity is one of the most important aspects of staff management; without adequate treatment adherence, behavior analysts are unable to determine whether treatment is effective, function has been identified, or intervention revisions are needed. The literature on staff management procedures has demonstrated that performance feedback and self-monitoring are effective procedures for increasing treatment integrity of behavior plans in the presence of the observer, however, few studies have evaluated the effectiveness of these procedures when the observer is absent. This study evaluated the effectiveness of performance …

Classification Models In Clinical Decision Making, Eleazar Gil-Herrera

USF Tampa Graduate Theses and Dissertations

In this dissertation, we present a collection of manuscripts describing the development of prognostic models designed to assist clinical decision making. This work is motivated by limitations of commonly used techniques to produce accessible prognostic models with easily interpretable and clinically credible results. Such limitations hinder prognostic model widespread utilization in medical practice.

Our methodology is based on Rough Set Theory (RST) as a mathematical tool for clinical data anal- ysis. We focus on developing rule-based prognostic models for end-of life care decision making in an effort to improve the hospice referral process. The development of the prognostic models is …

Effects Of Speech Production Ability On A Measure Of Speech Perception Capacity In Young Children With Cochlear Implants And Their Articulation-Matched Peers, Victoria Beatriz Gonzalez

USF Tampa Graduate Theses and Dissertations

With reductions in the age criterion for cochlear implantation, the need for age-appropriate measures of speech perception skills has increased. One recently developed tool that shows great promise for the clinical assessment of auditory speech perception capacity in young children with cochlear implants is the On-Line Imitative Test of Speech-Pattern Contrast Perception (OlimSpac). The OlimSpac requires a child to imitate nonword utterances by providing a verbal response. The child's perceptual abilities are inferred from the child's productions through having a listener, who is masked to the stimulus select the utterance produced by the child in an eight-alternative force-choice task. Although …

Asbestos Exposure In The Research Laboratory, Ediberto D. Garcia

USF Tampa Graduate Theses and Dissertations

Introduction: Asbestos has been employed in a myriad of industrial applications for more than a century. Of the 181 Mt of asbestos produced worldwide, over 31 Mt was consumed in the U.S. The production and consumption of this mineral eventually was found to cause asbestosis, lung cancer and mesothelioma. While the brunt of the human exposure to asbestos occurred in insulation work, many more workers in other jobs were expose to asbestos fibers. Very little is known about the potential exposure to asbestos in research labs.

Goal: In order to investigate potential research lab work exposures, we simulated lab work …

USF Tampa Graduate Theses and Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is one of the leading diagnoses for children. Children diagnosed with ADHD often have difficulty in many settings including at school as well as in the home. Medication is often a common treatment for these children, however, it has been often shown ineffective when used alone. A review of behavioral interventions, including various self-regulation interventions has been studied. Self-regulation interventions have been shown to be effective for children diagnosed with ADHD primarily in school or academic settings. The purpose of this study was to evaluate the effects of a self-management intervention on the on-task behavior of children …

Fate Of Polybrominated Diphenyl Ethers During Wastewater Treatment Process Producing Reclaimed Water, Kristy Siegel

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs), flame retardants, have been applied to consumer goods, such as furniture, electrical devices, textiles, and appliances for decades. Due to their physico-chemical properties, PBDEs are semi-volatile and easily leach off the consumer good during aging, stress, or normal wear and tear of the good. Once airborne, they pose an environmental health threat because they can adsorb onto dust particles, soil, or other particulates that can be inhaled, ingested, or come into contact with the dermal layer. Additionally, PBDEs have a molecular structure similar to other persistent organic pollutants, such as polychlorinated biphenyls and polychlorinated dibenzo-p-dioxins and …

The Acquisition And Usage Of The Sodas Problem Solving Method Among Adults At-Risk For Homelessness, Collin Edward Streetman

USF Tampa Graduate Theses and Dissertations

Individuals experiencing extended homelessness face multifaceted risks in physical health, nutrition, substance use, mental health, continuing unemployment, and incarceration. Some of these adults may benefit from learning a problem-solving decision-making method to assist them in dealing with everyday problems they encounter. This study taught three men with extensive histories of homelessness, but who were currently housed, the SODAS problem-solving decision-making method, and assessed their ability to learn it and guide another adult in the use of the method in simulated role-play problem situations. The acquisition of SODAS from behavioral rehearsal training was evaluated using a multiple-baseline design across participants' role …

Development Of An Investigator-Designed Questionnaire Concerning Childbirth Delivery Options Based On The Theory Of Planned Behavior, Chun-Yi Tai

USF Tampa Graduate Theses and Dissertations

This study responds to the globally increasing rate of caesarean section, and specifically to the very high rate of elective caesarean section among Taiwanese mothers as evidence suggests that such elective caesareans pose potential health risks for mothers and babies. The purpose of this study was to develop and evaluate a multi-component instrument based on the theory of planned behavior (TPB) to better understand Taiwanese pregnant women's decisions regarding their childbirth delivery options (spontaneous vaginal delivery or elective caesarean section). The study was a four-phased mixed method design. First, the TPB guided item development and instrument drafting. Second, pretesting and …

Development Of A Confirmatory Pcr Assay To Detect Onchocerca Volvulus In Pools Of Vector Black Flies, Alex Jeanne Talsma

USF Tampa Graduate Theses and Dissertations

Onchocerciasis, or river blindness, has historically represented one of the significant neglected tropical diseases on the planet in terms of socio-economic impact. The discovery that ivermectin was a safe and effective treatment for onchocerciasis, together with the decision of the manufacturer to donate the drug for the treatment of this disease became the basis for several large international programs to control and eventually eliminate the infection. These programs have managed to virtually eliminate transmission of the parasite causing Onchocerca volvulus from many foci in Africa and the Americas. Verifying that transmission has been halted requires sensitive and specific assays to …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine whether student outcomes are a function of participation in different modes of delivery in an Opticianry program at the community college level. First, the intent was to determine whether differences in instructional delivery methods and background characteristics impact student performance in an Opticianry program. The three instructional delivery methods were traditional face-to-face instruction, online delivery, and a hybrid format where students take theory courses online and attend face-to-face laboratories on campus. A second objective was to determine the role of background variables such as student age, which was the age when entering …

Evaluating The Effectiveness Of An Internet-Based Behavioral Program For Increasing Physical Activity With And Without A Behavioral Coach, Diego Alejandro Valbuena

USF Tampa Graduate Theses and Dissertations

Obesity is a problem of vast social concern in the United States. One factor that has been linked to reduction in body fat and the health problems associated with obesity is increasing physical activity. Although in-person behavioral interventions have been shown effective at increasing physical activity, attention is now being placed on disseminating these interventions through the use of technology. Several internet-based interventions have been developed and are readily available. The purpose of this study was to evaluate "Fitbit," a web-based behavioral intervention for increasing physical activity and losing weight. Additionally, this study examined if the addition of contact from …

Influence Of Maternal Thyroid Dysfunction On Infant Growth And Development, Ronee Elisha Wilson

USF Tampa Graduate Theses and Dissertations

Thyroid dysfunction is one of the most common endocrine disorders in women of childbearing age and the obstetric consequences of abnormal thyroid hormone levels during pregnancy have been established. Less understood is the implication of the presence of maternal thyroid autoantibodies on infant outcomes among women who are euthyroid during pregnancy. The objective of this study was two-fold: 1) to examine the influence of antenatal thyroperioxidase (TPO) status on fetal/infant brain and body growth measurements at delivery and 2) to explore the relationship of antenatal TPO status and maternal postpartum thyroid dysfunction (PPTD) on early infant growth and neurocognitive development. …

Prenatal Stress, Depression, And Herpes Viral Titers, Pao-Chu Hsu

USF Tampa Graduate Theses and Dissertations

Recent studies suggest that some cases of prenatal depression may be associated with reactivation of latent infections of the herpesvirus family. The possible relationships among stress, prenatal depression, and herpes viral reactivation in pregnancy are understudied and the molecular pathways such as the neuroimmune biogenic amine pathway are unidentified. Chronic stress shifts the T helper-1 cell (Th1) cytokine profile to a Th2 profile, which favors virus induced pathogenesis and survival. Pregnancy is also associated with a similar Th2 dominance. In non-pregnant individuals, exposure to psychological or physical stress may be associated with latent herpes viral reactivation and could result in …

A Monte Carlo Approach To Change Point Detection In A Liver Transplant, Alexia Melissa Makris

USF Tampa Graduate Theses and Dissertations

Patient survival post liver transplant (LT) is important to both the patient and the center's accreditation, but over the years physicians have noticed that distant patients struggle with post LT care. I hypothesized that patient's distance from the transplant center had a detrimental effect on post LT survival. I suspected Hepatitis C (HCV) and Hepatocellular Carcinoma (HCC) patients would deteriorate due to their recurrent disease and there is a need for close monitoring post LT. From the current literature it was not clear if patients' distance from a transplant center affects outcomes post LT. Firozvi et al. (Firozvi AA, 2008) …

Examining The Effectiveness Of Intensive Language Action Therapy In Individuals With Nonfluent Aphasia, Rachel A. Goff

USF Tampa Graduate Theses and Dissertations

Abstract

Background: Individuals with nonfluent aphasia may have significant difficulties with functional spoken communication tasks in their daily life. Aphasia treatment held in a group setting may provide an enriched communicative context wherein the requirements of spoken language are similar to those within functional day-to-day communicative situations. Thus engaging in a spoken language activity in a group setting may directly target generalization of trained skills to those required in real-life, social communication situations. The present study is concerned with an aphasia group treatment that requires focused practice of spoken language during a social-functional communication task. Intensive Language Action Therapy (ILAT) …
