The Phylogeny Of Rays And Skates (Chondrichthyes: Elasmobranchii) Based On Morphological Characters Revisited., Eduardo Villalobos-Segura, Giuseppe Marramà, Giorgio Carnevale, Kerin M. Claeson, Charlie J Underwood, Gavin J P Naylor, Jürgen Kriwet

PCOM Scholarly Works

Elasmobranchii are relatively well-studied. However, numerous phylogenetic uncertainties about their relationships remain. Here, we revisit the phylogenetic evidence based on a detailed morphological re-evaluation of all the major extant batomorph clades (skates and rays), including several holomorphic fossil taxa from the Palaeozoic, Mesozoic and Cenozoic, and an extensive outgroup sampling, which includes sharks, chimaeras and several other fossil chondrichthyans. The parsimony and maximum-likelihood analyses found more resolved but contrasting topologies, with the Bayesian inference tree neither supporting nor disfavouring any of them. Overall, the analyses result in similar clade compositions and topologies, with the Jurassic batomorphs forming the sister clade …

Faculty, Staff and Student Publications

Postpartum Depression (PPD) is the most common childbirth complication, with approximately 15% of postpartum women experiencing depression symptoms. Mobile applications have potential to expand delivery of mental health interventions. However, our understanding of how these tools engage women with PPD and facilitate positive behavioral changes is limited. In our paper, we analyze 15 commercial PPD applications to understand their role as facilitators of change, engagement, and sustained use. Applications reviewed contained an average of four theory-based behavioral change techniques, and highest patient engagement level reached was to empower patients through patient-generated data. Heuristic violations were identified in areas including user …

Unpacking Misinfodemic During A Global Health Crisis: A Qualitative Inquiry Of Psychosocial Characteristics In Social Media Interactions, Sofia M Olivares, Sahiti Myneni

Faculty, Staff and Student Publications

The pervasiveness of health information in social media has led to a modern misinformation crisis, also known as a misinfodemic. Misinfodemics have upended public health activities as clearly evident during the COVID-19 pandemic. The objective of this study is to characterize social media content and information sources using theory-driven health behavior and psychology constructs to better understand the motifs of misinformation and their role in the dissemination of health (mis)information in Twitter posts. We analyzed 1,400 randomly selected tweets related to COVID-19 to ascertain four important variables, what is the tweet about (content), how is it structured (linguistic features), who …

Latent Linguistic Motifs In Social Media Postings Resisting Covid-19 Misinformation, Tavleen Singh, Sofia Olivares, Sahiti Myneni

Faculty, Staff and Student Publications

Social media has become a predominant source of information for many health care consumers. However, false and misleading information is a pervasive problem in this context. Specifically, health-related misinformation has become a significant public health challenge, impeding the effectiveness of public health awareness campaigns and resulting in suboptimal responsiveness to the communication of legitimate risk-related information. Little is known about the mechanisms driving the seeding and spreading of such information. In this paper, we specifically examine COVID-19 tweets which attempt to correct misinformation. We employ a mixed-methods approach comprising qualitative coding, deep learning classification, and computerized text analysis to understand …

Reelin Supplementation For The Rescue Of Fragile X Syndrome., Nicole K. Morrill

USF Tampa Graduate Theses and Dissertations

Reelin is a large, extracellular matrix glycoprotein involved in neuronal migration during embryonic brain development and synaptic plasticity in the adult brain. Reelin consists of eight EGF-like repeats and undergoes natural cleavage at two sites, between repeats 2 and 3 and repeats 5 and 6, resulting in five naturally occurring fragments. The role of Reelin in the developing central nervous system has been extensively characterized, and loss of Reelin or disruption in the signaling cascade may contribute to the cognitive impairments seen in numerous neurodevelopmental or aging diseases such as schizophrenia, autism, depression, epilepsy, and Alzheimer’s disease. Reelin’s signaling potentiates …

Understanding The Tumor Microenvironment In Head And Neck Squamous Cell Carcinoma, Habib Sadeghi Rad, Yavar Shiravand, Payar Radfar, Rahul Ladwa, Chris Perry, Xiaoyuan Han, Majid Ebrahimi Warkiani, Mark N. Adams, Brett G.M. Hughes, Ken O'Byrne, Arutha Kulasinghe

Pacific Faculty Work

Head and neck squamous cell carcinoma (HNSCC) represents a heterogeneous group of tumors. While significant progress has been made using multimodal treatment, the 5-year survival remains at 50%. Developing effective therapies, such as immunotherapy, will likely lead to better treatment of primary and metastatic disease. However, not all HNSCC tumors respond to immune checkpoint blockade therapy. Understanding the complex cellular composition and interactions of the tumor microenvironment is likely to lead to new knowledge for effective therapies and treatment resistance. In this review, we discuss HNSCC characteristics, predictive biomarkers, factors influencing immunotherapy response, with a focus on the tumor microenvironment.

Research outputs 2022 to 2026

Continued growth in the number of published clinical studies has necessitated changes to the way evidence-based resources such as clinical guidelines are developed and updated. The Australian and New Zealand Clinical Guidelines for Stroke Management (https://informme.org.au/guidelines/clinical-guidelines-for-stroke-management) are based on continual evidence surveillance and timely updates to recommendations as new research is published. In this article, we outline the main updates to recommendations since the guidelines moved into a living mode in 2018, and discuss key challenges and benefits of living guidelines.

Changes In Insulin Sensitivity And Lipid Profile Markers Following Initial And Secondary Bouts Of Multiple Eccentric Exercises, Trevor C. Chen, Min Jyue Huang, Leonardo C. R. Lima, Tai Ying Chou, Hung Hao Wang, Jui Hung Tu, Shi Che Lin, Kazunori Nosaka

Research outputs 2022 to 2026

An acute bout of eccentric exercise affects insulin sensitivity and lipid profile, but how the magnitude of muscle damage affects them is not clear. We compared changes in blood insulin sensitivity and lipid markers after the first (EC1) and second (EC2) eccentric exercise bouts. Fifteen sedentary young men performed arm, leg and trunk muscle eccentric exercises, and repeated them 2 weeks later. Fasting blood samples were taken before, 2 h and 1–5 days after each exercise bout to analyze plasma creatine kinase (CK) activity, serum glucose (GLU), insulin, homeostasis model assessment (HOMA), triacylglycerols (TG), total (TC) and low- (LDLC) and …

UNLABELLED: Targeting immune checkpoints such as programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) has transformed cancer treatment, with durable clinical responses across a wide range of tumor types. However, a high percentage of patients fail to respond to anti-PD-1/PD-L1 treatment. A greater understanding of PD-L1 regulation is critical to improving the clinical response rate of PD-1/PD-L1 blockade. Here, we demonstrate that PD-L1 is phosphorylated and stabilized by casein kinase 2 (CK2) in cancer and dendritic cells (DC). Phosphorylation of PD-L1 at Thr285 and Thr290 by CK2 disrupted PD-L1 binding with speckle-type POZ protein, an adaptor …

The Effects Of Language Proficiency On Narrative Macrostructure In Spanish-English Bilinguals, Jenny Magallon

Dissertations and Theses

Bilingual children of the same age may have different narrative skills depending on the quantity and quality of their experiences in the two languages. Thus, children's storytelling skills can vary depending on children's oral proficiency in each language. The present study examined the effects of oral proficiency on story structure in forty 5- to 7-year-old Spanish-English speaking children using Spanish and English samples from story retelling tasks. Language proficiency was measured as continuum of performance using the Spanish-English Language Proficiency Scale (SELPS; Smyk et al., 2013). To estimate the effects of Spanish and English proficiency on story structure, linear regressions …

Biophysical Physiology Of Phosphoinositide Rapid Dynamics And Regulation In Living Cells, Jill B Jensen, Bjoern H Falkenburger, Eamonn J Dickson, Lizbeth De La Cruz, Gucan Dai, Jongyun Myeong, Seung-Ryoung Jung, Martin Kruse, Oscar Vivas, Byung-Chang Suh, Bertil Hille

Phosphoinositide membrane lipids are ubiquitous low-abundance signaling molecules. They direct many physiological processes that involve ion channels, membrane identification, fusion of membrane vesicles, and vesicular endocytosis. Pools of these lipids are continually broken down and refilled in living cells, and the rates of some of these reactions are strongly accelerated by physiological stimuli. Recent biophysical experiments described here measure and model the kinetics and regulation of these lipid signals in intact cells. Rapid on-line monitoring of phosphoinositide metabolism is made possible by optical tools and electrophysiology. The experiments reviewed here reveal that as for other cellular second messengers, the dynamic …

Quantifying Concordant Genetic Effects Of De Novo Mutations On Multiple Disorders, Hanmin Guo, Lin Hou, Yu Shi, Sheng Chih Jin, Xue Zeng, Boyang Li, Richard P Lifton, Martina Brueckner, Hongyu Zhao, Qiongshi Lu

2020-Current year OA Pubs

Exome sequencing on tens of thousands of parent-proband trios has identified numerous deleterious de novo mutations (DNMs) and implicated risk genes for many disorders. Recent studies have suggested shared genes and pathways are enriched for DNMs across multiple disorders. However, existing analytic strategies only focus on genes that reach statistical significance for multiple disorders and require large trio samples in each study. As a result, these methods are not able to characterize the full landscape of genetic sharing due to polygenicity and incomplete penetrance. In this work, we introduce EncoreDNM, a novel statistical framework to quantify shared genetic effects between …

Identifying Colorectal Cancer Caused By Biallelic Mutyh Pathogenic Variants Using Tumor Mutational Signatures, Peter Georgeson, Yin Cao, Et Al

2020-Current year OA Pubs

Carriers of germline biallelic pathogenic variants in the MUTYH gene have a high risk of colorectal cancer. We test 5649 colorectal cancers to evaluate the discriminatory potential of a tumor mutational signature specific to MUTYH for identifying biallelic carriers and classifying variants of uncertain clinical significance (VUS). Using a tumor and matched germline targeted multi-gene panel approach, our classifier identifies all biallelic MUTYH carriers and all known non-carriers in an independent test set of 3019 colorectal cancers (accuracy = 100% (95% confidence interval 99.87-100%)). All monoallelic MUTYH carriers are classified with the non-MUTYH carriers. The classifier provides evidence for a …

Prefrontal Cortex Supports Speech Perception In Listeners With Cochlear Implants, Arefeh Sherafati, Noel Dwyer, Aahana Bajracharya, Mahlega Samira Hassanpour, Adam T Eggebrecht, Jill B Firszt, Joseph P Culver, Jonathan E Peelle

2020-Current year OA Pubs

Cochlear implants are neuroprosthetic devices that can restore hearing in people with severe to profound hearing loss by electrically stimulating the auditory nerve. Because of physical limitations on the precision of this stimulation, the acoustic information delivered by a cochlear implant does not convey the same level of acoustic detail as that conveyed by normal hearing. As a result, speech understanding in listeners with cochlear implants is typically poorer and more effortful than in listeners with normal hearing. The brain networks supporting speech understanding in listeners with cochlear implants are not well understood, partly due to difficulties obtaining functional neuroimaging …

Newton

Research outputs 2022 to 2026

Introduction Obese men with prostate cancer have an increased risk of biochemical recurrence, metastatic disease and mortality. For those undergoing androgen deprivation therapy (ADT), substantial increases in fat mass are observed in the first year of treatment. Recently, we showed that a targeted supervised clinic-based exercise and nutrition intervention can result in a substantial reduction in fat mass with muscle mass preserved in ADT-treated patients. However, the intervention needs to be accessible to all patients and not just those who can access a supervised clinic-based programme. The purpose of this study was to evaluate the efficacy of telehealth delivered compared …

The Effect Of Fibrodysplasia Ossificans Progressiva On The Tongue, Amy Backal, Amanda Harrop, David J. Goldhamer Dr.

University Scholar Projects

FOP is a rare genetic disorder in which skeletal muscle and associated connective tissue progressively turn to bone through a process called heterotopic ossification (HO). The extra skeletal bone growth is cumulative, eventually trapping patients in a second skeleton that eventually leads to death by asphyxiation. The FOP mutation is autosomal dominant that can be inherited or acquired sporadically. Unfortunately, FOP is currently incurable with no therapeutic options to inhibit bone growth or reduce existing bone nodules. My project intends to further our understanding of the cellular mechanisms of the disease within the tongue muscle. A population of cells known …

A Preliminary Study Of Proinflammatory Cytokines And Depression Following West Nile Virus Infection, Allison Lino, Timothy A. Erickson, Melissa Nolan Ph.D., Mph, Kristy O. Murray, Shannon E. Ronca

Faculty Publications

West Nile virus (WNV) is a neurotropic flavivirus that can cause acute febrile illness leading to neuroinvasive disease. Depression is a well-described outcome following infection, but the underlying pathogenic mechanisms are unknown. Proinflammatory cytokines play important roles in WNV infection, but their role in depression post-WNV remains unstudied. This research aimed to retrospectively evaluate associations between proinflammatory cytokines and new onset depression in a WNV cohort. Participants with asymptomatic WNV infection were significantly less likely to report new onset depression when compared to those with symptomatic disease. Participants with encephalitis and obesity were significantly more likely to report new onset …

Following Arksey and O'Malley's scoping study methodology and aligned with the PRISMA-ScR guidelines on the reporting of scoping reviews, the authors searched, charted, collated, and summarized …

Schizophrenia And Social Stigma: How Society Views Those With Mental Illness, Rebecca Littrel

Undergraduate Research Symposium

Mental Illness is one of the most stigmatized diseases in the media today. Patients diagnosed with schizophrenia are more likely to have depression, more likely to commit suicide, and less likely to hold a job and be covered by insurance companies. How society views mental illness needs to change. Mental health professionals often feel stigmatized for their jobs as well.

Synthesis Of Curcumin Derivatives: Increasing Compound Stability, Chloe Wilke

Undergraduate Research Symposium

Curcumin (C₂₁H₂₀O₆), the main active component in the spice Turmeric, has many recognized health benefits ranging from anti-inflammatory agents to the suppression of the proliferation of tumors. Curcumin has been used worldwide as an antiseptic and treatment for inflammatory conditions, arthritis, and sepsis. This water-insoluble molecule is unstable and degrades quickly upon entering the body. In order to preserve the beneficial structure of curcumin before it is broken down by the digestive system, carbohydrates are attached to alter the compound, increasing polarity and solubility. This topic was researched by analyzing multiple journal articles and …

Generalized Anxiety Disorder: Challenges In Everyday Life, Chloe Wilke

Undergraduate Research Symposium

Generalized Anxiety Disorder is one of the leading mental illnesses in the United States, affecting 6.8 million adults. Having a mental disorder can lead to stigmatization, isolation, and changes in interpersonal relations. The recent psychiatric approach to these types of diseases equates them to physical illnesses in both importance and concern. This project will examine articles and journals that include social context for mental illness along with current issues that are prevalent in society such as treatments and social stigmas. Discrediting, rejection, and ostracization based on bias and prejudices result in lower self-esteem, contributing to the severity or presence of …

Malaria: Existence Perpetuated By A Counterfeit Drug Industry, Nicholas Black

Undergraduate Research Symposium

Malaria is a mosquito-borne disease that has plagued society for thousands of years. Malaria is often overlooked from the perspective of wealthier industrialized countries due to prevention efforts largely eliminating malaria from these locations. However, overlooking malaria’s continued global relevance is misinformed to the fact that nearly half the global population lives in regions at risk of malarial transmission. According to the CDC and WHO, such a high number of people at risk has subsequently led to an estimated 241 million cases and over 627 thousand deaths in 2020 alone. The purpose for the present research is to examine the …

Staph Infection: Hospitals Battle Against A Deadly Menace, Mckenzie Lamos

Undergraduate Research Symposium

Staph infection is caused by the staphylococcus bacteria, which is found on the skin or within the nose of even healthy individuals. This bacteria is usually harmless, but deadly infectious diseases may arise when it enters deep within the body. Staph infection is commonly treated with antibiotics, however the methicillin-resistant Staphylococcus aureus (MRSA) strain is resistant to antibiotics which further complicates treatment. This research provides insight on preventative measures to stop and slow the spread of staph infection in hospitals, along with what is being done to limit the number of MRSA infections. The CDC and NCBI both outline strategies …

Resolving The Repression Pathway Of Virulence Gene Hila In Salmonella, Alexandra King, Lon Chubiz Phd, Brenda Pratte, Lauren Daugherty

Undergraduate Research Symposium

Salmonella is a relatively abundant, virulent species of bacteria that is most known for spreading gastrointestinal diseases through food. These illnesses result in approximately 1.35 million infections, including over 25,000 hospitalizations each year, in the U.S. alone (CDC.gov). As antibiotic resistance becomes an increasingly urgent public health problem, the importance of developing alternative treatment methods is only becoming more crucial. One of the genes responsible for this virulence is known as hilA. HilA is the main transcriptional regulator of Salmonella Pathogenicity Island-1 gene (UniProt). SPI-1 plays an important role in the invasion of Salmonella into epithelial cells. The proteins encoded …
