Primary Liver Cancers, Part 2: Progression Pathways And Carcinogenesis, Kun Jiang, Barbara A. Centeno
Pathology and Cell Biology Faculty Publications
Hepatocellular carcinoma (HCC) and primary intrahepatic cholangiocarcinoma (ICC) have been increasing in incidence worldwide and are leading causes of cancer death. Studies of the molecular alterations leading to these carcinomas provide insights into the key mechanisms involved. A literature review was conducted to identify articles with information relevant to current understanding of the etiologies and molecular pathogenesis of HCC and ICC. Chronic inflammatory diseases are the key etiological risk factors for both HCC and ICC, although other diseases play a role, and for many ICCs, an underlying risk factor is not identified. Mutations in catenin beta 1 (CTNBB1) …

A literature review was conducted to identify articles with information relevant to precancerous precursors, current histopathological classification, ancillary testing, and risk stratification of primary malignant liver tumors. The histomorphology of normal liver, preinvasive …
Astaxanthin Attenuates Mptp Induced Neurotoxicity And Modulates Cognitive Function In Aged Mice, Beth Grimmig
Astaxanthin Attenuates Mptp Induced Neurotoxicity And Modulates Cognitive Function In Aged Mice, Beth Grimmig
USF Tampa Graduate Theses and Dissertations
Parkinson’s disease is the second common neurodegenerative disease and is most frequently diagnosed in individuals over 60. There are no available medications that can prevent or restore the loss of neurons that correspond to motor impairments in patients. Identifying novel therapeutic compounds that are capable of slowing and reversing the extensive neurodegeneration that occurs in PD remains an important goal of the field. While basic research has identified potential therapeutic agents, studies often use young model organisms to demonstrate efficacy of the target compound. This approach ignores the impact of the aged CNS on the disease process, and likely contributes …
Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder
Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder
USF Tampa Graduate Theses and Dissertations
Optimal decision-making entails outcome evaluation, comparing received costs and benefits with predicted costs and benefits. The anterior cingulate cortex (ACC), a brain area with major connections to the appetitive and aversive motivation systems, may provide the neural substrate of this evaluation process. One way to measure the relative contribution of these systems on decision-making is to measure individual differences in risk-taking behaviors. For individuals who make risky choices, this evaluation step may be biased: some show a preference for immediate, short-term rewards (increased appetitive system), while devaluing the long-term consequences of their choices (decreased aversive system). However, most studies supporting …

The rodent navigation system has been the focus of study for over a century. Discoveries made lately have provided insight on the inner workings of this system. Since then, computational approaches have been used to test hypothesis, as well as to improve robotics navigation and learning by taking inspiration on the rodent navigation system.
This dissertation focuses on the study of the multi-scale representation of the rat’s current location found in the rat hippocampus. It first introduces a model that uses these different scales in the Morris maze task to show their advantages. The generalization power of larger scales of …
Receptor-Associated Protein (Rap) Models In Vivo Reelin Haploinsufficiency: Implications In Schizophrenia, Jamileh Ahmed
Receptor-Associated Protein (Rap) Models In Vivo Reelin Haploinsufficiency: Implications In Schizophrenia, Jamileh Ahmed
USF Tampa Graduate Theses and Dissertations
The “two-hit” schizophrenia hypothesis suggests genetic and environmental abnormalities interrupt early CNS function. This increases vulnerability of a “second hit” and schizophrenia onset. Chronic stress and decreased Reelin signaling are reportedly associated with schizophrenia. Heterozygous Reeler Mice (HRM) show a 50% reduction in Reelin and display major schizophrenia phenotypes. Receptor-Associated Protein (RAP) blocks ligand-association to Reelin receptor Apolipoprotein E receptor 2 (ApoER2). In this study, we sought to replicate major heterozygous reeler mouse (HRM) phenotypes using in vivo RAP studies to establish an experimental in vitro model. Using an in vitro model, we investigated the effects of chronic stress and …
Acetaminophen Associated Neurotoxicity And Its Relevance To Neurodevelopmental Disorders, Seol-Hee Kim
Acetaminophen Associated Neurotoxicity And Its Relevance To Neurodevelopmental Disorders, Seol-Hee Kim
USF Tampa Graduate Theses and Dissertations
Autism is a lifelong neurodevelopmental disorder. The etiology of autism still remains unclear due to the heterogeneous and complex nature of the disorder, however synergistic actions between genetic components and environmental factors have been suggested. Acetaminophen (APAP) is one of the most popular over-the-counter drugs that possess antipyretic and analgesic effects. It is considered a relatively safe and effective within therapeutic doses. Recently, early exposure to APAP has been suggested to be one of the underlying cause of autism. Children are often prescribed APAP to lessen fever or irritability after vaccination during the first year, and APAP may adversely affect …
Neuropeptide Modulation Of The Large Conductance Potassium (Bk) Channel In The Auditory System: Therapeutic Implications For Age-Related Hearing Loss, Ellliott James Brecht
Neuropeptide Modulation Of The Large Conductance Potassium (Bk) Channel In The Auditory System: Therapeutic Implications For Age-Related Hearing Loss, Ellliott James Brecht
USF Tampa Graduate Theses and Dissertations
The auditory temporal processing deficits associated with age-dependent hearing decline have been increasingly attributed to issues beyond peripheral hearing loss. Age-related hearing loss (ARHL), also known as presbycusis, is linked with changes in the expression of both excitatory and inhibitory neurotransmitters in the central auditory system. There are also age-related changes in the expression and function of the ion channels which mediate action potential firing. The slow, Ca2+ activated, K+ channels of the BK-type are essential in controlling both neurotransmitter release and neural communication via alteration of action potential durations, firing frequency, and neural adaptation. There are many …
The Potential Role Of Antiretroviral Efavirenz In Hiv Associated Neurocognitive Disorders, Lecia Ashanna Moya Brown
The Potential Role Of Antiretroviral Efavirenz In Hiv Associated Neurocognitive Disorders, Lecia Ashanna Moya Brown
USF Tampa Graduate Theses and Dissertations
The prevalence of milder forms of HIV-associated neurocognitive disorders (HAND) is rising despite combination antiretroviral therapy (cART). Efavirenz (EFV) is among the most commonly used antiretroviral drugs globally, but causes neurological symptoms that may interfere with adherence and reduce tolerability, and may have central nervous system (CNS) effects that contribute in part to HAND in patients on cART. Thus we evaluated a commonly used EFV containing regimen: EFV/zidovudine (AZT)/lamivudine (3TC) in murine N2a cells transfected with the human “Swedish” mutant form of amyloid precursor protein (SweAPP N2a cells) to assess for promotion of amyloid-beta (Aβ) production (Chapter 3). Treatment with …
Tau-Directed Immunotherapy For Alzheimer’S Disease, Sulana Kay Schroeder
Tau-Directed Immunotherapy For Alzheimer’S Disease, Sulana Kay Schroeder
USF Tampa Graduate Theses and Dissertations
Alzheimer’s disease (AD) is the leading cause of dementia, accounting for 50 to 80 percent of dementia cases, and the prevalence of the disease is projected to increase significantly with time. AD is characterized by severe cognitive decline with age, ultimately requiring continued caregiving and eventually death. The pathology of AD is characterized by the presence of extracellular amyloid plaques, intracellular neurofibrillary tangles (NFT) composed of hyperphosphorylated tau protein, neuron loss, and evidence of inflammation indicated by the presence of reactive microglia and astrocytes. Frontotemporal Lobe Dementia (FTLD) is a rare form of dementia that is related to AD, most …
Mass-Spectrometry Based Proteomics Of Age-Related Changes In Murine Microglia, Antwoine Flowers
Mass-Spectrometry Based Proteomics Of Age-Related Changes In Murine Microglia, Antwoine Flowers
USF Tampa Graduate Theses and Dissertations
The last century has seen a steady increase in the extension of the average lifespan. This has concomitantly produced higher incidences of age-related chronic degenerative diseases like Alzheimer’s and Parkinson’s diseases. Age is the single greatest risk factor for the development of not just these degenerative conditions but cancer as well. The aged niche undergoes a number of maladaptive changes that allow underlying conditions to present and progress. Exactly which changes, contribute to the progression of which disease is currently an area of intense study. However, these answers often present therapeutic targets for disease prevention. Age is characterized by a …
Parts Of The Whole: Error Estimation For Science Students, Dorothy Wallace
Parts Of The Whole: Error Estimation For Science Students, Dorothy Wallace
Numeracy
It is important for science students to understand not only how to estimate error sizes in measurement data, but also to see how these errors contribute to errors in conclusions they may make about the data. Relatively small errors in measurement, errors in assumptions, and roundoff errors in computation may result in large error bounds on computed quantities of interest. In this column, we look closely at a standard method for measuring the volume of cancer tumor xenografts to see how small errors in each of these three factors may contribute to relatively large observed errors in recorded tumor volumes.

Bone is the one of the most common distant metastatic sites in breast cancer. Routine initial breast cancer staging evaluation typically includes computed tomography (CT) and skeletal scintigraphy while 18F fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) is reserved for clinically high-risk cases. Since FDG PET-CT is not routinely performed during staging or surveillance evaluations, it is important for radiologists and clinicians to appreciate the limitations of bone metastasis detection on CT and scintigraphy. We present a case of bony metastases of invasive ductal carcinoma of the breast which were not detected on diagnostic CT or skeletal scintigraphy but were …
The Effects Of Synthetic And Dietary Therapeutics On Learning, Memory, Motor Coordination, And Seizure In An Angelman Syndrome Mouse Model, Stephanie Lynn Ciarlone
The Effects Of Synthetic And Dietary Therapeutics On Learning, Memory, Motor Coordination, And Seizure In An Angelman Syndrome Mouse Model, Stephanie Lynn Ciarlone
USF Tampa Graduate Theses and Dissertations
Angelman syndrome (AS) is a rare genetic and neurological disorder presenting with severe developmental delay, ataxia, epilepsy, and lack of speech. AS is associated with a neuron-specific loss of function of the maternal UBE3A allele, a gene encoding an E3 ubiquitin ligase. Currently, no cure exists for this disorder; however, recent research using an AS mouse model suggests that pharmacological intervention is plausible, and can alleviate some of the detrimental phenotypes reported in AS patients.
Although there is no curative treatment for AS, seizure medication and behavioral therapies are most commonly prescribed in order to minimize symptoms. However, these options …
Hypercapnic Hyperoxia Increases Free Radical Production And Cellular Excitability In Rat Caudal Solitary Complex Brain Slice Neurons, Geoffrey Edward Ciarlone
Hypercapnic Hyperoxia Increases Free Radical Production And Cellular Excitability In Rat Caudal Solitary Complex Brain Slice Neurons, Geoffrey Edward Ciarlone
USF Tampa Graduate Theses and Dissertations
The caudal solitary complex (cSC) is a cardiorespiratory integrative center in the dorsal medulla oblongata that plays a vital role in the central CO2-chemoreceptive network. Neurons in this area respond to hypercapnic acidosis (HA) by a depolarization of the membrane potential and increase in firing rate, however a definitive mechanism for this response remains unknown. Likewise, CO2-chemoreceptive neurons in the cSC respond to hyperoxia in a similar fashion, but via a free radical mediated mechanism. It remains unknown if the response to increased pO2 is merely an increase in redox signaling, or if it’s the …
Regulation Of Palmitoylation Enzymes And Substrates By Intrinsically Disordered Regions, Krishna D. Reddy
Regulation Of Palmitoylation Enzymes And Substrates By Intrinsically Disordered Regions, Krishna D. Reddy
USF Tampa Graduate Theses and Dissertations
Protein palmitoylation refers to the process of adding a 16-carbon saturated fatty acid to the cysteine of a substrate protein, and this can in turn affect the substrate’s localization, stability, folding, and several other processes. This process is catalyzed by a family of 23 mammalian protein acyltransferases (PATs), a family of transmembrane enzymes that modify an estimated 10% of the proteome. At this point in time, no structure of a protein in this family has been solved, and therefore there is poor understanding about the regulation of the enzymes and their substrates. Most proteins, including palmitoylation enzymes and substrates, have …
Hormone Replacement Therapy (Hrt) Modulates Peripheral And Central Auditory System Processing With Aging, Tanika Williamson
Hormone Replacement Therapy (Hrt) Modulates Peripheral And Central Auditory System Processing With Aging, Tanika Williamson
USF Tampa Graduate Theses and Dissertations
After the findings were reported for the Women’s Health Initiative (WHI) study in the past decade, there has been a significant decline in the overall use of hormone replacement therapy (HRT) among women. However, there are still millions of middle-aged, menopausal women in the U.S. who are currently undergoing hormone therapy. Their reasons for continuing treatment include relief of severe menopausal symptoms, aid in the management of osteoporosis and reduction in the risk of colon cancer (Ness et al., 2005). The purpose of the following investigation was to evaluate the impact of HRT on the central and peripheral auditory systems …
Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
USF Tampa Graduate Theses and Dissertations
Animal models of ocular hypertension are important for glaucoma research but come with experimental costs. Available methods of intraocular pressure (IOP) elevation are not always successful, the amplitude and time course of IOP changes are unpredictable and irreversible, and IOP measurement by tonometry is laborious. This dissertation focuses on the development and implementation of two novel systems for monitoring and controlling IOP without these limitations. The first device consists of a cannula implanted in the anterior chamber of the eye, a pressure sensor that continually measures IOP, and a bidirectional pump driven by control circuitry that can infuse or withdraw …
Designing The Haptic Interface For Morse Code, Michael Walker
Designing The Haptic Interface For Morse Code, Michael Walker
USF Tampa Graduate Theses and Dissertations
Two siblings have a muscular degenerative condition that has rendered them mostly blind, deaf and paraplegic. Currently, the siblings receive communication by close range sign language several feet in front of their vision. Due to the degenerative nature of their condition, it is believed that the siblings will eventually become completely blind and unable to communicate in this fashion. There are no augmented communication devices on the market that allow communication reception for individuals who cannot see, hear or possess hand dexterity (such as braille reading). To help the siblings communicate, the proposed communication device will transmit Morse code information …
The Concerted Regulation Of Intracellular Signaling By Amyloid Precursor Protein And Aβ Peptide, Lisa Kirouac
The Concerted Regulation Of Intracellular Signaling By Amyloid Precursor Protein And Aβ Peptide, Lisa Kirouac
USF Tampa Graduate Theses and Dissertations
It is widely accepted that A-beta (Aβ) generated from amyloid precursor protein (APP) oligomerizes and fibrillizes to form neuritic plaques in the Alzheimer’s disease (AD) brain, yet little is known about the contribution of APP preceding AD pathogenesis. Our data presented here suggest that APP has a functional role in cell cycle regulation and proliferation. First, we demonstrat that APP is pathologically phosphorylated at Thr668 and that P-APP localizes to the centrosomes. Furthermore, P-APP is proteolytically processed in a cell cycle -dependent manner to generate its pathogenic metabolites. Using Stable Isotope Labeling by Amino Acids in Culture (SILAC) and …
Static And Dynamic Spectral Acuity In Cochlear Implant Listeners For Simple And Speech-Like Stimuli, Benjamin Anderson Russell
Static And Dynamic Spectral Acuity In Cochlear Implant Listeners For Simple And Speech-Like Stimuli, Benjamin Anderson Russell
USF Tampa Graduate Theses and Dissertations
For cochlear implant (CI) listeners, poorer than normal speech recognition abilities are typically attributed to degraded spectral acuity. However, estimates of spectral acuity have most often been obtained using simple (tonal) stimuli, presented directly to the implanted electrodes, rather than through the speech processor as occurs in everyday listening. Further, little is known about spectral acuity for dynamic stimuli, as compared to static stimuli, even though the perception of dynamic spectral cues is important for speech perception.
The primary goal of the current study was to examine spectral acuity in CI listeners, and a comparison group of normal hearing (NH) …
The Influence Of Motivational Salience On Attention Selection: An Erp Investigation, Constanza De Dios
The Influence Of Motivational Salience On Attention Selection: An Erp Investigation, Constanza De Dios
USF Tampa Graduate Theses and Dissertations
The current study used event-related potentials (ERPs) to investigate how motivational salience in the form of expectation violation influences spatial attention. The medial frontal negativity (MFN) ERP indexes expected value, being negative to unexpected punishments and positive to unexpected rewards. The P1 and N1 ERPs index spatial attention, being larger to stimuli in attended locations. This design attached motivational value to locations by making one visual hemifield economically rewarding (greater probability of a rewarding outcome) and the other punishing (greater probability of a punishing outcome). Keypresses to a dot probe following a reward-signifying stimulus were awarded money if correct, and …
Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert
Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert
USF Tampa Graduate Theses and Dissertations
Glaucoma is a neurodegenerative protein misfolding disorder classified by increases in IOP, damage to retinal ganglion cells (RGCs), optic nerve (ON) head damage, and progressive irreversible blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma, constituting over 90% of clinical cases. POAG is observed in patients where normal outflow channels, mainly the trabecular meshwork (TM), are exposed at the angle formed by the iris and cornea. However, due to TM cellular dysfunction, aqueous outflow resistance is increased preventing normal circulation of aqueous humor. Recent studies have shown that in 2-4% of POAG cases, increased intracellular levels of …
The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes
The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes
USF Tampa Graduate Theses and Dissertations
With the growing older adult population, neurodegenerative diseases common in old age such as mild cognitive impairment (MCI) or Parkinson’s disease (PD) are becoming increasingly germane areas of research. Pharmacological treatments have thus far been unsuccessful in treating cognitive decline associated with these neurodegenerative disorders. Alternative interventions, such as cognitive training programs, have shown promise. The current dissertation contains three papers examining cognitive interventions in neurodegenerative diseases. The first paper examined the longitudinal effects of cognitive speed of processing training (SPT) among those with PD. Results showed that training gains seen at initial post-test were maintained three months later. The …
Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin
Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin
USF Tampa Graduate Theses and Dissertations
Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation. More recently …
