Exosomes: Antiviral Agents In The Human Lung, Jennifer Alexandra Novak

Master's Theses

Hundreds of interferon effectors comprise the immediate host response to virus infection. One family of interferon stimulated genes is the IFITM (Interferon-Induced Transmembrane) proteins. IFITM3, in particular, has been shown to block virus cell entry of Influenza A Virus, SARS Coronavirus, and West Nile Virus, among others. IFITM3 has also been identified as an essential factor for host protection against Influenza A Virus in mice and humans. However, the mechanism by which IFITM3 functions remains unclear.

IFITM3 may function both intracellularly and extracellularly to block virus infection in the human lung. The extracellular milieu contains microscopic vesicles termed exosomes which …

The Interactive Effects Of Coping Strategies, Gender, And Stress In The Prediction Of Internalizing Symptoms In African American Youth: An Application Of The Specificity Model, Cynthia Pierre

Master's Theses

The current study utilized a specificity framework in the examination of interactions among coping strategies, stressor domains, and participant gender in the prediction of depressive and anxiety symptoms. Participants were 273 African American adolescents (6th - 8th; mean age = 12.9; 58% female). Participants completed measures of universal and culturally-relevant coping strategies in response to a stressor. Stressors were coded by raters across dichotomous domains: interpersonality (interpersonal vs. non-interpersonal), duration (acute vs. chronic), controllability (controllable vs. non-controllable), and sexuality (sexual vs. non-sexual). T-tests were conducted to examine differences in reported coping across stress domains. Inconsistent with predictions, mean differences of …

The Relation Of Executive Functions To Active Coping Strategies And Internalizing Symptoms In A Community Sample Of African-American Youth, Arie Zakaryan

Master's Theses

The purpose of this study is to examine the relations between stressor appraisals, active coping, executive functions, and internalizing symptoms in a community sample of low-income African-American youth. There is a dearth of studies assessing how executive functions influence the connection between coping and internalizing symptoms, notably in community and minority populations. When faced with distressing, uncontrollable settings straining the capacity to self-regulate, youth with executive functioning deficits may encounter greater challenges in coping with stressors. Yet, since typically adaptive active coping strategies do not benefit some youth and can result in negative outcomes, it is important to identify what …

Assessing The Effects Of Titanium Dioxide Nanoparticles On Microbial Communities In Stream Sediment Using Artificial Streams And High Throughput Screening, Alexandra Ozaki

Master's Theses

Nano-titanium dioxide (nano-TiO2) is an engineered nanomaterial used in a wide array of commercial products. The production and use of large amounts of nano-TiO2 is resulting in the unintended release to the environment. Nano-TiO2 is known to be cytotoxic due primarily to its ability to generate reactive oxygen species, and negative impacts on a variety of organisms have been demonstrated, but the effects of nano-TiO2 on complex microbial communities under ecologically relevant conditions have rarely been tested. We conducted a controlled manipulative experiment using recirculating model streams dosed with a one-time amendment of 1mg L-1 nano-TiO2 (specifically P25). Within one …

Antibodies To Inhibit Clostridium Difficile Adhesion To Human Gut Epithelial Cell Line, Wonbeom Paik

Master's Theses

Clostridium difficile infection (CDI) is a major hospital-acquired diarrhea that can cause life-threatening complications such as pseudomembranous colitis. CDI is caused by colonization of host with C. difficile, a Gram positive, anaerobic bacterium known to produce toxins that cause disease. Normally, the gut microbiota protects the host from CDI, but disruption of the microbial composition through antibiotic treatment can leave one vulnerable for CDI. To date, no vaccines for preventing CDI are available.

In this study, the potential of antibodies directed against specific surface molecules of C. difficile to block bacterial adherence to host gut epithelial cells was studied, in …

Prevention And Detection Of Intrusions In Wireless Sensor Networks, Ismail Butun

USF Tampa Graduate Theses and Dissertations

Wireless Sensor Networks (WSNs) continue to grow as one of the most exciting and challenging research areas of engineering. They are characterized by severely constrained computational and energy

resources and also restricted by the ad-hoc network operational

environment. They pose unique challenges, due to limited power

supplies, low transmission bandwidth, small memory sizes and limited energy. Therefore, security techniques used in traditional networks cannot be directly adopted. So, new ideas and approaches are needed, in order to increase the overall security of the network. Security applications in such resource constrained WSNs with minimum overhead provides significant challenges, and is the …

Physicians As Gatekeepers: Uncovering Barriers And Facilitators To Participation In A Prostate Cancer Prevention Intervention Clinical Trial, Theresa T. Crocker

While prior research has described barriers to participation in therapeutic clinical trials, much less in known about barriers related to participation in trials aimed at prevention, prostate cancer prevention in particular. Physicians have been shown to play a critical role in access to trials; however, less is known about the individual and structural factors that influence their participation in prostate cancer prevention trials. This research provides rich ethnographic detail within the context of an ongoing trial. Research participants included physician/investigators …

Self-Interference In Ofdm-Based Systems: Identification And Separation, Ertugrul Guvenkaya

USF Tampa Graduate Theses and Dissertations

Orthogonal frequency-division multiplexing (OFDM) is communication technique that is robust against multipath spread, efficient in equalization implementation, and flexible in dynamic spectrum usage. With the need of wideband signals in high data rate communications, OFDM has gained widespread attention and usage as an efficient way of implementing multicarrier communication. Despite its prominent advantages, received signal quality degrades because of inter-symbol interference (IS) and inter-carrier interference (ICI) due to insufficient guard time in multipath channels and time variance as well as hardware impairments in OFDM systems. When several of the impairments occurs simultaneously, interferences combine at the receiver side. Thus, interference …

The Role Of Connectedness And Religious Factors On Bullying Participation Among Preadolescents In Puerto Rico, Melissa C. Mercado-Crespo

USF Tampa Graduate Theses and Dissertations

Relationships or connections with caring pro-social others (e.g., parents, teachers, school, friends, neighborhood, religion) serve as pro-resilience assets that may enhance children's abilities to cope with bullying. The purpose of this research study was to explore the roles of connectedness and religiosity as potential factors that could enhance resiliency against bullying among preadolescents in Puerto Rico (PR). This doctoral dissertation also addressed several gaps in the children's bullying, resilience and religiosity research literature.

Prescribing Physical Activity To Prevent And Manage Gestational Diabetes, Sheri R. Colberg, Kristin Castorino, Lois Jovanovič

Human Movement Studies & Special Education Faculty Publications

Gestational diabetes mellitus (GDM) is the most prevalent metabolic disorder during pregnancy. Women diagnosed with GDM have a substantially greater risk of developing type 2 diabetes within 5-10 years after delivery, and the risk is increased by excess body weight. Uncontrolled hyperglycemia during pregnancy is potentially harmful to both mother and fetus, resulting in a greater need for Caesarian-section deliveries, delivery of larger infants with more excess body fat, a greater risk of infant death and stillbirth, and an elevated risk of infant hypoglycemia immediately after birth. Fortunately, engaging in physical activity prior to and during pregnancy may lower the …

Violet Van Der Elst's Use Of Spectacle And Militancy In Her Campaign Against The Death Penalty In England, Lizzie Seal

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

Violet van der Elst launched her campaign against the death penalty in the mid-1930s. She employed direct action tactics outside prisons on execution morning, such as leading the crowd in song and breaking through police cordons. These were not only designed to engage and include the crowd that was present, but also to grab the attention of newspaper readers. Her approach to campaigning made deliberate use of spectacle and, coupled with her direct action techniques, can be understood as a form of post-suffragette militancy. This article explores the influence of the legacy of the suffragette movement on Violet van der …

A Reassessment Of The Conservation Status Of A Critically Endangered Neotropical Frog, Mannophryne Olmonae, Using Occupancy Modeling Techniques, Jessica Mcquigg

Senior Independent Study Theses

Amphibian species worldwide are threatened with decline and extinction, making species monitoring an important scientific endeavor. The Bloody Bay Poison Frog, Mannophryne olmonae, a Tobago island endemic, was identified as critically endangered by the IUCN in 2004. Recent evidence suggests that a less severe conservation status may be appropriate for M. olmonae. This study employs acoustic calling surveys, land-use information, and multi-year (2011 and 2012) occupancy modeling techniques to propose an appropriate conservation status for this species. This study suggests that M. olmonae occupies a larger geographic range than was previously thought, and is not experiencing population declines. …

Knowledgeable Learning And Conceptual Change: Value Adding To Teacher Training, Tony Yeigh

Australian Journal of Teacher Education

This report concerns the use of pre and post responses to an online questionnaire as evidence of knowledgeable learning by education students at a regional Australian university. Factor analysis was used to reveal conceptual changes in the students’ thinking about classroom management across a unit of learning they had undertaken. These changes primarily involved movement from an authoritarian, rule-based management approach, toward a more differentiated, inclusive approach to management. The implications these changes have for unit delivery, as well as for validation of the engagement process, are discussed, and recommendations made concerning ongoing research and the design of online learning.

P900: A Putative Novel Erp Component That Indexes Counter-Measure Use In The P300-Based Concealed Information Test, John B. Meixner Jr., Elena Labkovsky, J. Peter Rosenfeld, Michael R. Winograd, Michael Winograd, Alexander Sokolovsky, Jeff Weishaar, Tim Ullmann

Scholarly Works

Countermeasures pose a serious threat to the effectiveness of the Concealed Information Test (CIT). In a CIT experiment, Rosenfeld and Labkovsky in Psychophysiology 47(6):1002–1010, (2010) observed a previously unknown positive ERP component at about 900 ms poststimulus at Fz and Cz that could potentially serve as an index of countermeasure use. Here, we explored the hypothesis that this component, termed P900, occurs in response to a signal that no further specific response is required in a trial, and could thus appear in countermeasure users that respond differentially depending on the stimulus that appears. In the present experiments, subjects viewed four …
