Multivariate Anti-Inflammatory Approaches To Rescue Neurogenesis And Cognitive Function In Aged Animals, Sandra Antonieta Acosta

USF Tampa Graduate Theses and Dissertations

Studies have shown that there is a strong correlation between aging and neurodegenerative diseases. Aging is considered the number one risk factor to develop neuropathologies such as memory loss, senile dementia, Alzheimer's disease (AD), and Parkinson's disease. Neurodegenerative diseases tend to start during adulthood, and aggravate over time, making them difficult to prevent and to treat. In the Unites States, demographic studies by U.S. Bureau of the Census have determined that our aging population of >65 years is expected to increase from the present 35 million to 78 million in 2030. This would result, not only to an increase of …

Does D-Cycloserine Augmentation Of Cbt Improve Therapeutic Homework Compliance For Pediatric Obsessive Compulsive Disorder?, Jennifer M. Park

USF Tampa Graduate Theses and Dissertations

D-cycloserine (DCS), a partial agonist that acts on the N-methyl-D-aspartate (NMDA) receptor of the glutamatergic receptor complex, may enhance fear extinction learning during exposure-based therapy. Clinical studies in adults with obsessive-compulsive disorder (OCD) and non-OCD anxiety disorders - and a recent trial in pediatric OCD - have shown that DCS can improve treatment response to exposure therapy relative to placebo and exposure therapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS and homework compliance in …

Modeling And Surveillance Of Pandemic Influenza Outbreaks, Diana Prieto

USF Tampa Graduate Theses and Dissertations

Pandemic outbreaks are unpredictable as to their virus strain, transmissibility, and impact on our quality of life. Hence, the decision support models for mitigation of pandemic outbreaks must be user-friendly and operational, and also incorporate valid estimates of disease transmissibility and severity. This dissertation research is aimed at 1) reviewing the existing pandemic simulation models to identify their implementation gaps with regard to usability and operability, and suggesting research remedies, 2) increasing operability of simulation models by calibrating them via an epidemiological model that estimates infection probabilities using viral shedding profiles of concurrent pandemic and seasonal influenza, and 3) developing …

Egyptian Body Size: A Regional And Worldwide Comparison, Michelle H. Raxter

USF Tampa Graduate Theses and Dissertations

Human body size and limb proportions can provide important information about adaptation, population movements, and health disparities. This study investigated changes in body size and limb proportions of adult Egyptians temporally and geographically in relation to climatological, sociopolitical and economic developments. It was predicted that Egyptian groups that experienced more environmental stress would be shorter and exhibit less sexual dimorphism. It was also predicted that Egyptians would be intermediate between higher and lower latitude populations in body form and limb length ratios. The main skeletal sample consisted of 492 males and 528 females, all adults from the Predynastic and Dynastic …

Apparent Total Evaporative Resistance For Clothing Ensembles At High Heat Stress Levels, Patrick Rodriguez

USF Tampa Graduate Theses and Dissertations

Donning protective clothing for mitigation of hazard from chemical agents poses a problem in the form of heat stress. When choosing protective clothing, many factors must be taken into account including insulative properties and evaporative resistance. This study calculated and compared R_e,T,a for three clothing ensembles at levels of heat stress past the level of compensation for heat gain to determine if R_e,T,a values varied or remained the same with changes in heat stress level. A three-way mixed model analysis of variance demonstrated significant differences for estimated R_e,T,a values among ensembles, heat stress levels and interactions among …

Secreted Factors From Human Umbilical Cord Blood Cells Protect Oligodendrocytes From Ischemic Insult, Derrick Rowe

USF Tampa Graduate Theses and Dissertations

Oligodendrocytes (OL)s are the dominant cell type in the white matter and are integral for synaptic transmission essential for proper neuronal communication between brain areas. Previous studies have shown that intravenous administration of the mononuclear fraction of human umbilical cord blood (HUCB) cells in rat models of stroke reduced white matter injury, gray matter injury and behavioral deficits. Yet the mechanisms used by HUCB cells remain unknown in ischemic injury. These studies will investigate both in vitro and in vivo approaches to elucidate this mechanism in OLs. When mature primary OLs were coincubated with HUCB cells, HUCB cells secreted soluble …

Disciplinary Outcomes By Race And Gender In Schools Implementing Positive Behavior Support: Does Fidelity Of Implementation Reduce Disproportionality?, Therese Sandomierski

USF Tampa Graduate Theses and Dissertations

Disparities in behavioral outcomes for minority students are a decades-old problem. Recently, the systems-level approach of school-wide positive behavior support (SW-PBS) and its growing research base have garnered attention as a possible remedy. Although SW-PBS has been shown to be effective in reducing a school's overall level of office discipline referrals (ODRs) and suspensions (OSS), and its success has been replicated in schools with large populations of minority students, effective outcomes across all groups of students within a school are not guaranteed. Some reports document increases in the magnitude of disproportionality even when ODRs and OSS decrease for the school …

Decision Aid Models For Resource Sharing Strategies During Global Influenza Pandemics, Alfredo Santana Reynoso

USF Tampa Graduate Theses and Dissertations

Pandemic influenza outbreaks have historically entailed significant societal and economic disruptions. Today, our quality of life is threatened by our inadequate preparedness for the imminent pandemic. The key challenges we are facing stem from a significant uncertainty in virus epidemiology, limited response resources, inadequate international collaboration, and the lack of appropriate science-based decision support tools. The existing literature falls short of comprehensive models for global pandemic spread and mitigation which incorporate the heterogeneity of the world regions and realistic travel networks. In addition, there exist virtually no studies which quantify the impact of resource sharing strategies among multiple countries. This …

USF Tampa Graduate Theses and Dissertations

In this dissertation is proposed a methodology to identify patient's recovery patterns after cardiovascular surgery based on laboratory tests results. The main purpose is to enhance the understanding of the manifestations of postsurgical complications in patients who underwent cardiovascular surgery. The analysis of patients' recovery process is based on the relationship between plasma calcium, ionized calcium and platelet count over time.

Laboratory results from the James A. Haley Veterans' Hospital databases, related to patients admitted to the Surgical Intensive Care Unit (SICU) after cardiac surgery (coronary artery bypass, aortic value replacement and mitral valve replacement), are used. These databases contain …

The Relationship Of Mid-Pregnancy Levels Of Cytokines, Stress, And Depression With Gestational Age At Delivery, Melissa Molinari Shelton

USF Tampa Graduate Theses and Dissertations

Pregnancy is a time of alternating states of inflammation. The establishment of pregnancy is marked by controlled inflammation and transition toward an anti-inflammatory state for much of the gestational period before returning to an inflammatory state at the onset of labor. Stress and depression trigger the HPA Axis to produce cortisol and levels are maintained in a state of elevation during pregnancy and continue to rise before parturition.

The aim of this research was to explore the relationship of gestational age at delivery with mid-pregnancy levels of cytokines, stress and depression. Participant samples (N = 122) were collected between 16 …

Perspective Shifting In Relative Clauses By Elementary-Aged Spanish-English Bilinguals: A Cross-Linguistic Study, Xigrid Tayri Soto

USF Tampa Graduate Theses and Dissertations

Language-specific theories of sentence processing suggest that individuals interpret sentences based on the characteristics of their native language (e.g., Bates & MacWhinney, 1989). As such, competing linguistic cues are taken into account (including word order, morphology, and animacy) and the cue selected is most likely to yield a correct interpretation in the native language. However, research in this area has produced conflicting results. MacWhinney (2005) has proposed that examining the role of perspective shifting in sentence comprehension may demonstrate how cognitive and syntactic factors work together to facilitate sentence comprehension. The aim of the current study is to investigate the …

Sisters In Arms: A Case Study Of The Experiences Of Women Warriors In The United States Military, Carmen Teresa Stein-Mccormick

USF Tampa Graduate Theses and Dissertations

Presently there are few studies that describe the current experiences of women warriors relative to issues such as sexual hostility, sexual harassment, and other uncommon experiences during their military careers. Very little is known about how being a woman in a male-dominated military may affect women warriors' choices between making the military a career or returning to civilian life. With better understanding of women warriors' military experiences, mental health professionals, educators, and other human services professionals may have a better understanding of the issues that may affect women in the military. To date there are limited studies that have examined …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

Participants 50 years and older (N=330) from the 2002 wave of the Survey of Inmates in Local Jails (SILJ) were studied via descriptive analysis, factor analysis, and a logistic regression to determine which variables were related to the probability of having a mental health problem. 65.8% of participants …

The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman

USF Tampa Graduate Theses and Dissertations

This paper describes a sequence of experiments addressing basic questions about the control of visual attention and the relationship between attention and object recognition. This work reviews compelling findings addressing attentional control on the basis of high-level perceptual properties. In five experiments observers were presented with a rapid sequence of object photographs and instructed to either detect or selectively encode a verbally cued object category. When these object categories (e.g. "baseball") were preceded by contextual images associated with a given object category (e.g. "baseball diamond"), observers were less likely to accurately report information about the target item. This effect obtained …

Indicators Of Early Adult And Current Personality In Parkinson's Disease, Kelly Sullivan

USF Tampa Graduate Theses and Dissertations

Introduction: Previous epidemiologic studies suggest that the personality of Parkinson's disease (PD) patients differs from that of controls, and laboratory evidence supports a potential common pathophysiology of personality traits and PD. One nested case-control study found that PD cases were significantly more anxious than controls before the clinical onset of the disease, and additional data suggest that certain occupations may be risk factors for the disease. Additionally, the latent period that precedes the onset of motor symptoms of PD is unknown.

Objectives: The objectives of this study were to evaluate the association of PD with objective indicators of current and …

Growing Up With Hiv: Disease Management Among Perinatally Infected Adolescents, Barbara J. Szelag

USF Tampa Graduate Theses and Dissertations

Children born with HIV in the 1980s and 1990s are surviving into adolescence and adulthood, due to the availability of highly active antiretroviral therapy (HAART). Growing up with a chronic and stigmatized disease presents considerable challenges as young people explore their sexuality, develop relationships, and take steps to become independent and productive adults. Adherence to HAART is an essential and life-long practice for the maintenance of health and longevity. For adolescents born with HIV, a daily medication schedule is one aspect of disease management that also includes medical visits, HIV status acceptance, bouts of illness, and disclosure of HIV status …

Patient Safety In Nursing Homes, Kali Thomas

USF Tampa Graduate Theses and Dissertations

Safety of residents has gained increased popularity in recent years following a report from the Institute of Medicine attributing 98,000 hospital deaths each year to errors by staff. As a result, regulatory agencies, advocates, and health care providers have shifted their focus to understanding patient safety and developing a culture that promotes safety. However, nursing homes lag behind other health care providers in their adoption of a patient safety culture and understanding what factors affect safety in resident care. These insights are needed to ensure that nursing home residents receive the safe care.

The purpose of this dissertation is to …

The Effects Of Manipulating Conditioned Establishing Operations On The Acquisition Of Mands In Children With Autism Spectrum Disorders, Claudia Troconis

USF Tampa Graduate Theses and Dissertations

In Verbal Behavior, Skinner (1957) suggested that each verbal operant has independent response functions, in which acquiring one does not automatically result in the other, unless transfer between the verbal operants is directly trained. Although several researchers have shown that mands and tacts are functionally independent, more recent research has demonstrated that mands may emerge following tact training. However, this research has not clarified the influence of establishing operations on the emergence of pure mands following tact training. Therefore, the present study investigated the effects of tact training on the acquisition of impure and pure mands in children with autism …

Detection Of Polybrominated Diphenyl Ethers In Ambient Air At A Wastewater Treatment Facility In Tampa, Florida, Brenda L. White

USF Tampa Graduate Theses and Dissertations

The goal of this study was to quantify the ambient air concentrations of polybrominated diphenyl ethers (PBDEs) from three locations within the Howard Curren Wastewater Treatment Facility located in Tampa, Florida. PBDEs have been linked to endocrine disruption, cancer, developmental concerns in children, as well as other toxic effects; however their precise roles concerning these deleterious effects remains to be determined. The present study was motivated by these potential health concerns posed by inhalational exposure to PBDEs. Ambient air was monitored with a Tisch Environmental PUF high volume sampler for 48 hours with collection on three types of media-quarts filter, …

Sharps Injuries In Medical Training: Higher Risk For Residents Than For Medical Students, Rachel Williams

USF Tampa Graduate Theses and Dissertations

Because of their relative inexperience in performing procedures and handling sharps devices, medical students and resident physicians are considered to be at high risk for sharps injuries. A higher rate of sharps injuries for medical trainees implies a higher risk for occupationally-acquired infection with bloodborne pathogens and may have financial and legal implications for training institutions. This study examines the prevalence of sharps injuries among US medical students and resident physicians. A systematic review of the literature yielded 10 studies that gave data on sharps injuries for US medical students or residents, and those data were combined with data from …

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …
