Assessing Prevalence Of Blood Parasites And Ranaviruses In Hong Kong Freshwater Turtles, Julia Leung

Lingnan Theses (MPhil & PhD)

Blood parasites and ranaviruses are pathogens that impact freshwater turtles worldwide. Given that native turtle species in Hong Kong are already at a high risk of extinction, their survival becomes even more threatened in the event of a disease outbreak. However, prevalence of these pathogens among the native population in Hong Kong remains unstudied.

In this study, I aim to (1) obtain baseline prevalence data of blood parasites and ranaviruses in Hong Kong freshwater turtles, (2) compare different methods for detecting blood parasites and ranaviruses, (3) evaluate the applicability of using blood parasites as a wildlife forensic tool, assess and …

The Association Between Environmental Factors And Substance Use Outcomes Among A Vulnerable Veteran Population, Leah Nixon Bryan

All ETDs from UAB

Background. Illicit substance use among veterans is a complex and multifaceted issue. As individuals who have served in the armed forces return to civilian life, they may face a range of challenges, including mental health issues, physical injuries, and difficulties readjusting to societal norms. Unfortunately, for some veterans, these challenges can contribute to the allure of illicit substances as a coping mechanism. The intersection of the unique stressors associated with military service creates a population with an increased vulnerability to select health and psychosocial issues and susceptible to substance misuse (Tsai & Rosenheck, 2015). In addition to military experiences, environmental …

The Relationship Of Sleep Disturbance And Disease-Related Factors On Neural And Neurocognitive Function In Youth Living With Sickle Cell Disease, Tiffany Devaughn Tucker

All ETDs from UAB

Youth living with sickle cell disease (SCD) often face neurocognitive challenges, regardless of accompanying neurological issues. SCD involves red blood cell deformation, leading to complications including chronic anemia, vaso-occlusion, and acute crises such as pain and overt stroke. While screening and intervention advancements have improved survival, enhancing functional capacity and quality of life (QoL) remains a targeted area of intervention. Disease-related factors, sleep disturbances, and social determinants significantly impact neurocognitive health in youth living with SCD. Deficits across all cognitive domains, including attention, working memory, and executive function (EF), are common, affecting academic achievement and QoL. Brain-related issues, such as …

Mapping Work Histories And Measuring Work Quality: Differences By Race, Gender, And Motherhood, Clifford James Ross

All ETDs from UAB

It is well-established that work has a strong association with health and that work is also a key driver of health inequality. However, there is little research that incorporates multiple components of work into one cohesive measure and examines how work patterns unfold over the life course. By incorporating three theoretical frameworks (1) The Sociology of Work and Health, (2) The Life Course, and (3) The Stress Process, and using over 40 years of employment data (collected from 1979-2018) from the National Longitudinal Survey of Youth 1979 (N=3,302), I introduce a comprehensive work measure called “Work Quality”. Then, using work …

Surface-Engineered Nano/Micro-Hybrid Polymer Systems For Environmental Health And Safety, Renjith Rajan Pillai

All ETDs from UAB

Environmental pollution involves the introduction of harmful substances into the natural environment, leading to detrimental effects on ecosystems, wildlife, and human health. This dissertation aims to advance comprehension of environmental pollution and explore efficient, environmentally friendly, and cost-effective methods of remediation. Recently, there has been increasing concern about the environmental impact of Polycyclic Aromatic Hydrocarbons (PAHs), a subgroup of Volatile Organic Compounds (VOCs), and Heavy Metals (HMs) pollution, both known for their carcinogenic and mutagenic properties. These pollutants can significantly harm human health through inhalation, ingestion, or contact with contaminated soil, potentially resulting in conditions such as encephalopathy, kidney dysfunction, …

A Histone Methyltransferase Contributes To Treatment Resistance In Npm1c Aml, Neha Srinivas

All ETDs from UAB

Acute myeloid leukemia (AML) is a blood cancer marked by the rapid growth of abnormal myeloid cells, driven by various genetic mutations. AML accounts for approximately 1% of all cancers and presents complicated prognosis and treatment. Menin inhibitors have shown potential in targeting AML. However, resistance to these inhibitors presents a significant clinical obstacle, as patients treated with menin inhibitors are increasingly developing resistance to the treatment. Using CRISPR-Cas9 mediated screening, we identified an epigenetic regulator contributing to resistance against menin inhibitors in AML. Utilizing knockout (KO) models of the epigenetic regulator in-vitro, ex-vivo, and in-vivo, we observed a growth …

Improving Molecular Diagnosis Success Rates And Prognosis Prediction For Patients With Rare Diseases, Tarun Karthik Kumar Mamidi

All ETDs from UAB

Rare diseases are medical conditions that affect a small number of people compared to the general population. There are more than 10,000 estimated rare diseases with 80% being genetic in origin, which although individually have a relatively low prevalence, collectively impact the lives of hundreds of millions of people worldwide. The diagnosis process is usually difficult and slow, but an accurate and early diagnosis can be crucial for disease treatment and management. This dissertation focuses on some of the important problems in this area by investigating the application of advanced machine learning methods to enhance the accuracy, precision, and efficiency …

Investigating The Impacts Of Staphylococcus Aureus Small Colony Variant Infection In The Cystic Fibrosis Rat Lung, Gretchen E. Bollar

All ETDs from UAB

Cystic fibrosis (CF) is an autosomal-recessive genetic disease characterized by recurrent and chronic airway infections. Staphylococcus aureus is currently the most common organism isolated from the CF lung, but its role as a pathogen has been historically difficult to characterize due to a broad range of genetic diversity and subtypes seen across infectious strains. Small colony variants (SCVs) are a subpopulation of S. aureus marked by slow growth rate and impaired metabolism that have been associated with worse respiratory outcomes in people with CF (pwCF). SCVs also exhibit altered colony morphology and can confound the results of traditional diagnostic assays, …

Interactions Between Oral Cancer Cells And Enterococcus Fecalis And Their Impact On Perineural Invasion, Sree Ramya Bhamidipaati

All ETDs from UAB

Oral and oropharyngeal squamous cell cancers (OSCC and OPSCC) are some of the most common cancers in the world. The overall 5-year survival rate is 68.5%, which drops to 39.3% in patients with later-stage cancers. This research aims to evaluate the effects of Enterococcus faecalis (E. faecalis) on the OSCC and OPSCC's tumor progression. E. faecalis is associated with asymptomatic, persistent endodontic infections and was found at a higher rate in OSCC patients. We hypothesize that cancer cells and Enterococcus faecalis (Ef) interact to affect the tumorigenic properties of oral cancer cells. OSCC cells from different parts of the oral …

Understanding Biopsychosocial Influences On Physical Activity And Quality Of Life In Breast Cancer Survivors, Erica A. Schleicher

All ETDs from UAB

Receiving a breast cancer diagnosis and subsequent treatment can be life-altering, presenting numerous challenges. Breast cancer treatments are effective at allowing women to live longer, but often impose long-term side-effects that survivors must manage for years. Exercise is an effective way to address many long-term side-effects of breast cancer treatment, yet 63-83% of breast cancer survivors do not meet recommended physical activity (PA) guidelines. Due to the complexity of cancer and treatment options, cancer-related factors have potential biopsychosocial impacts that can influence exercise habits, attitudes toward PA (i.e., social cognitive theory (SCT) constructs), and potentially quality of life (QoL). It …

The Effect Of Progranulin On Lysosomal Function In Bv2 Cells, Michelle Park

All ETDs from UAB

Neurodegenerative diseases afflict nearly 7 million people in United states, constituting a significant portion of the 600 known neurological disorders. Characterized by the gradual loss of neurons and axons within the central nervous system (CNS), these conditions stem from chronic inflammatory activation of the brain. Chronic inflammation disrupts important processes such as autophagy lysosome pathway, a self-degradative process that eliminates protein aggregates and damaged organelles. Trehalose, a non-reducing disaccharide that triggers autophagic flux in neuronal cells and promotes the clearance of protein aggregates; however, without understanding the mechanism behind how trehalose affects these functions, it lacks value. In our study, …

Approach-Avoidance Action Patterns As Indicators Of Empathic ‘Care Drive’ Strength, Stephanie R. Hruza

USF Tampa Graduate Theses and Dissertations

Empathy, care, and prosocial behavior are essential to social group cohesion, and antisocial and violent criminal behavior, on the other pole, can cause serious disruptions in group cohesion and negatively impact society as a whole. Different psychopathological conditions tend to present with impairments in affective empathy/caring and prosocial behavior, as is observed in psychopathic traits, which are tied to antisocial behavior and outcomes. It is essential to understand how empathy and care function, both in psychopathology and normal prosocial functioning, in order to inform interventions for empathy/care deficits and avoid the potential harm that such deficits can cause for others …

Parp-1 Selectively Impairs Kras-Driven Phenotypic And Molecular Features In Intrahepatic Cholangiocarcinoma, Friederike L Keggenhoff, Darko Castven, Diana Becker, Stojan Stojkovic, Jovana Castven, Carolin Zimpel, Beate K Straub, Tiemo Gerber, Harald Langer, Patricia Hähnel, Thomas Kindler, Jörg Fahrer, Colm J O'Rourke, Ursula Ehmer, Anna Saborowski, Lichun Ma, Xin Wei Wang, Timo Gaiser, Matthias S Matter, Christian Sina, Stefanie Derer, Ju-Seog Lee, Stephanie Roessler, Bernd Kaina, Jesper B Andersen, Peter R Galle, Jens U Marquardt

Objective: Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer with limited therapeutic options. KRAS mutations are among the most abundant genetic alterations in iCCA associated with poor clinical outcome and treatment response. Recent findings indicate that Poly(ADP-ribose)polymerase1 (PARP-1) is implicated in KRAS-driven cancers, but its exact role in cholangiocarcinogenesis remains undefined.

Design: PARP-1 inhibition was performed in patient-derived and established iCCA cells using RNAi, CRISPR/Cas9 and pharmacological inhibition in KRAS-mutant, non-mutant cells. In addition, Parp-1 knockout mice were combined with iCCA induction by hydrodynamic tail vein injection to evaluate an impact on phenotypic and molecular …

Fibrotic Response To Anti-Csf-1r Therapy Potentiates Glioblastoma Recurrence, Spencer S Watson, Anoek Zomer, Nadine Fournier, Joao Lourenco, Manfredo Quadroni, Agnieszka Chryplewicz, Sina Nassiri, Pauline Aubel, Simona Avanthay, Davide Croci, Erik Abels, Marike L D Broekman, Douglas Hanahan, Jason T Huse, Roy T Daniel, Monika E Hegi, Krisztian Homicsko, Giulia Cossu, Andreas F Hottinger, Johanna A Joyce

Faculty, Staff and Student Publications

Glioblastoma recurrence is currently inevitable despite extensive standard-of-care treatment. In preclinical studies, an alternative strategy of targeting tumor-associated macrophages and microglia through CSF-1R inhibition was previously found to regress established tumors and significantly increase overall survival. However, recurrences developed in ∼50% of mice in long-term studies, which were consistently associated with fibrotic scars. This fibrotic response is observed following multiple anti-glioma therapies in different preclinical models herein and in patient recurrence samples. Multi-omics analyses of the post-treatment tumor microenvironment identified fibrotic areas as pro-tumor survival niches that encapsulated surviving glioma cells, promoted dormancy, and inhibited immune surveillance. The fibrotic treatment …

Swimming Performance, But Not Metabolism, Is Related To A Boldness-Activity Syndrome In Schoolmaster Snapper (Lutjanus Apodus), Peter Malorey, Emma S. Porter, A. Kurt Gamperl, Mark Briffa, Alexander D.M. Wilson

School of Biological and Marine Sciences

Commercial overexploitation and climate change can alter the physiology and behavior of marine organisms, although intraspecific phenotypic responses to such changes can vary greatly depending on the environment, species, and severity of the stressor. Under the pace-of-life syndrome (POLS) hypothesis, behavior, physiology, and life-history traits are linked, and thus, affected by selection targeting any aspect of organismal biology. However, these links are understudied in tropical marine fishes, and further work is needed to better understand the impacts of fisheries and climate change on wild stocks. Moreover, tropical regions have a greater reliance on fisheries; thus investigations should focus on species …

Domain-Based Nucleic-Acid Minimum Free Energy: Algorithmic Hardness And Parameterized Bounds, Erik D. Demaine, Elize Grizzell, Jayson Lynch, Ahmed Shalaby, Timothy Gomez, Markus Hecher, Robert Schweller, Damien Woods

Computer Science Faculty Publications

Molecular programmers and nanostructure engineers use domain-level design to abstract away messy DNA/RNA sequence, chemical and geometric details. Such domain-level abstractions are enforced by sequence design principles and provide a key principle that allows scaling up of complex multistranded DNA/RNA programs and structures. Determining the most favoured secondary structure, or Minimum Free Energy (MFE), of a set of strands, is typically studied at the sequence level but has seen limited domain-level work. We analyse the computational complexity of MFE for multistranded systems in a simple setting were we allow only 1 or 2 domains per strand. On the one hand, …

BACKGROUND: The utilization of genomic information to improve health outcomes is progressively becoming more common in clinical practice. Nonetheless, disparities persist in accessing genetic services among ethnic minorities, individuals with low socioeconomic status, and other vulnerable populations. The Rio Grande Valley (RGV) at the Texas-Mexico border is predominantly Hispanic/Latino with a high poverty rate and very limited access to genetic services. Funded by the National Center for Advancing Translational Sciences, Project GIVE (Genetic Inclusion by Virtual Evaluation) was launched in 2022 to reduce the time to diagnosis and increase provider knowledge of genomics in this region, with the goal of …

Hyperglycemia And Venous Thromboembolism, Neha Panchagnula, William Philip Brasher

Faculty, Staff and Students Publications

Patients with diabetes mellitus (DM) have chronically increased blood glucose and multiple physiologic alterations that place them at elevated risk for vascular disease. Traditionally, this vascular risk has mainly referred to chronic atherosclerosis and embolic arterial disease. Retrospective studies have suggested an increased risk of a pulmonary embolism (PE) and deep vein thrombosis (DVT), collectively termed venous thromboembolism (VTE), in patients with DM, but this association has been difficult to demonstrate with comorbidities such as obesity in meta-analysis. Clinical studies have demonstrated worse outcomes for patients with DM who suffer from VTE. In vitro studies show multiple physiologic abnormalities with …

Design Thinking Strategies For Complex Situations: Covid-19 In Western Australia And New South Wales, Terence Love, Paul Cozens, Trudi Cooper

Research outputs 2022 to 2026

This paper outlines an argument for changing the foundation of design thinking practices to include causal feedback loops instead of primarily predicting futures using linear causal relations. The paper suggests for most real-world design situations the traditional linear causal perspective is insufficient and leads to lower value design outcomes. The authors propose instead designers address real-world complex design situations via design methods that include feedback loops, which require different design methods and tools. The discussion in the paper follows the understanding of systems researchers. The authors provide an example of the significant differences in outcomes using a comparative case study …

Therefore, discovering a balance between economic progress and environmental conservation is paramount. To decipher the vulnerability of Taiwan's coastal zones, this study first defines ‘Integrated Environmental Vulnerability of Coastal Areas.’Key vulnerability factors were identified across environmental, social, and economic dimensions. Seven core determinants were determined using the Fuzzy Delphi method: biodiversity, coastal erosion, water pollution, population density, population aging, land utilization, and …

Evalution Of The Ability To Infer Tilt Angle And Size Distributions Of Fish Using A Broadband Scientific Echosounder Based On Simulation, Jing Liu

Journal of Marine Science and Technology–Taiwan

The biological information, such as species, size, and tilt angle, is crucial for converting the echo data into biomass information in acoustic surveys. Typically, the information can be obtained through trawl net sampling or underwater camera observations. However, both methods have some limitations. To overcome these limitations, scientists have utilized inversion methods with multi-frequency and broadband echosounders to derive biological information about fish, plankton, and krill. However, evaluating the reliability and accuracy of these inversion methods has been challenging due to the difficulty in obtaining accurate biological information. In this study, a numerical simulation method was used to generate fish …
