A Novel Role For Enos In Regulating Lymphatic Valve Development During Embryogenesis, Drishya Iyer

USF Tampa Graduate Theses and Dissertations

Lymphedema is a disease that occurs when lymph flow is impaired, resulting in tissue swelling, fibrosis, chronic inflammation and recurrent secondary infections. Lymphatic valves play a critical role in maintaining unidirectional lymph flow and evidence for valve defects have been reported in lymphedema patients. The lack of drugs that can correct lymphatic valve defects warrants a better understanding of the molecular regulators of lymphatic valve development and maintenance. Lymphatic valves first develop during embryogenesis in response to mechanotransduction signaling pathways triggered by oscillatory lymph flow. Since eNOS (gene name: Nos3) is a well characterized mechanotransduction signaling molecule in blood vessels, …

Contribution Of Contextual Factors And Neuropathology To Dementia, Monica E. Nelson

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that has extensive biological heterogeneity. It is not clear the extent to which this heterogeneity may be detected in participants without dementia, how it relates to incident AD dementia, and whether contextual factors may change how neuropathology relates to incident AD dementia. Therefore, this dissertation was completed using data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI; n = 1,703) and the Czech Brain Aging Study (CBAS; n = 385) to address the following aims: to assess biological heterogeneity in participants without dementia, to relate this heterogeneity to incident AD dementia, and to …

Preliminary Data Of Potentially Hazardous Radon Concentrations In Modrič Cave (Croatia), Robert Lončarić, Vanja Radolić, Maša Surić, Igor Miklavčić, Matea Šatalić, Dalibor Paar, Lukrecija Obšivač

International Journal of Speleology

Instigated by relatively high cave-air CO₂ concentrations in Modrič Cave (Croatia) recorded for the purpose of speleothem-based paleoclimate research, we established preliminary monitoring of radon (²²²Rn) concentrations within the cave for a 4.5-year period (2018–2022). As radioactive geogenic gas, radon, which often correlates with cave-air CO₂ concentrations, presents a potential health hazard in cases of longer exposure time in high concentration conditions. Since the Modrič Cave is open to tourists and long-term scientific research has been performed within, a safety assessment for radon concentrations was essential. The integrated measurements of radon concentrations were performed by passive …

Exploring The Risk Narratives Of Transgender People Engaged In Do-It-Yourself Hormone Replacement Therapy, Brianna Rae Cusanno

USF Tampa Graduate Theses and Dissertations

This dissertation analyzed the risk narratives of transgender people engaged in do-it- yourself hormone replacement therapy. Transgender (trans) people, those whose gender identities and/or expressions defy normative constructions of gender, experience a variety of health inequities as a consequence of systemic oppression within U.S. society. Many of the health inequities observed in trans people can be traced to structural determinants, such as discrimination at home, work, and school that results in housing, food, and social instability. Yet, medical and public health researchers have often attributed trans health inequities to “high risk” behaviors in which trans people engage.

One such behavior …

An Evaluation Of Measurement Invariance Of Dsm-5 Borderline Personality Disorder Criteria Across Heterosexual, Lesbian, Gay, And Bisexual Adults, E. Elisa Carsten

USF Tampa Graduate Theses and Dissertations

There is a robust, yet poorly understood relationship between non-heterosexual orientation and borderline personality disorder (BPD), with lesbian, gay, and bisexual individuals evidencing greater BPD symptoms compared to heterosexual individuals. Recent evidence suggests possible bias in BPD diagnostic criteria leading to greater endorsement among sexual minority individuals, which hinders researchers’ ability to make valid group comparisons. The present study utilized an epidemiological sample of 35,995 men and women to evaluate the extent of differential item functioning (DIF) among BPD criteria across sexual orientation groups using a multiple indicators multiple causes (MIMIC) approach. All criteria except affective instability and emptiness indicated …

Examining The Role Of Executive Functions On The Intention-Behavior Gap Of Alcohol Harm Reduction Strategy Use, Becky K. Gius

USF Tampa Graduate Theses and Dissertations

Alcohol harm reduction strategies are health behaviors that aim to minimize the likelihood or severity of consequences associated with alcohol use. Despite the demonstrated usefulness of harm reduction strategies, there is variability in who and when the strategies are used, leading to the question “if they work, why not use them all the time?” One potential explanation is a discrepancy between the intention to drink safely and actually drinking safely, termed the intention-behavior gap. It is unclear to what extent college drinkers plan on engaging in safe drinking behaviors but fail to follow through. It is plausible some drinkers have …

Investigating Risk Factors Of The Development Of Compulsive Exercise And Eating Disorder Symptoms In College Students, Madeline Palermo

USF Tampa Graduate Theses and Dissertations

Compulsive exercise (e.g., high exercise frequency combined with the inability to reduce or stop exercising) is associated with a variety of maladaptive outcomes in college students, such as quality of life impairment, body dissatisfaction, and poor physical health outcomes. Recent research suggests that compulsive exercise is highly prevalent among college students and that engagement in compulsive exercise behaviors may increase over the first year of college. Given that college is an important developmental period for establishing behavioral patterns that affect long-term health, developing effective preventative interventions for compulsive exercise among early college students is paramount. Extant cross-sectional work suggests that …

Development Of A Low-Cost Tool For The Compositional Measurement Of Gases Derived From Mineral Water Wells From The Eastern Carpathians, Szalay Roland, Kis Boglárka-Mercedesz

Studia UBB Geologia

The Eastern Carpathians host CO₂-rich, low temperature, dry gas vents, bubbling pools and wells/drillings, which were established for the extraction of mineral water and CO₂ for the bottling industry. These wells can provide important information on the structure of the geological deposits, the depths, and the source of the gases, because they are often located at important geologic/tectonic sites. Our aim was to test the applicability of a hand-made and low-cost tool in preselected wells/drillings, in order to measure the concentration of different gas species. This was challenging due to the high water and gas discharge of …

Flexible Magnetic Skin Sensor Array For Torsion Perception, Lucja Stawikowska, Erik D. Engeberg

Florida Conference on Recent Advances in Robotics

Prosthetic hands help upper limb amputees and people who were born without hands. Currently, these prostheses are rather rudimentary and do not provide adequate sensing capabilities compared to a human hand. People use their natural hands to perceive complex tactile phenomena such as shear and torsion using thousands of mechanoreceptors in their fingertips. The capability to detect torsional loads at the fingertips is a notable gap in prosthetic hand sensation. Flexible tactile sensors are a promising new technology that would be ideal for prosthetic hands since they allow for stretching and movement like human skin without damage to the sensor. …

An Experimental Study Of Negative Performance Feedback: Consideration Of A Cognitive Pathway And Individual Difference Factors, Ansley M. Bender

USF Tampa Graduate Theses and Dissertations

Negative performance feedback is relatively common and may be related to negative mental health outcomes, but there is a lack of sufficient experimental research. Further, little is known about the pathway by which effects emerge, or factors that may enhance or attenuate resilience to the effects of negative performance feedback. There is preliminary support for a cognitive pathway through appraisals of falling short of standards, but this specific model remains untested. Likewise, research suggests that perfectionism and positive future thinking may affect resilience in the context of negative performance feedback. The present study was among the first to experimentally test …
