Nauli, Surya M. Nauli

Pharmacy Faculty Articles and Research

Background

Hepatitis B virus (HBV) establishes persistent infection through the formation of a covalently closed circular DNA (cccDNA) minichromosome, which enables immune evasion and sustained viral replication. While SIRT1, IFI16, and STING are known to modulate antiviral pathways, their cooperative role in regulating HBV transcription and host immunity remains poorly defined.

Methods

We investigated the functional interplay between SIRT1, IFI16, and STING using confocal microscopy, chromatin immunoprecipitation (ChIP), gene silencing, and quantitative PCR in HBV-replicating cell models. Interactions with HBV cccDNA and effects on viral transcription and interferon-stimulated gene (ISG) expression were analyzed. Northern blotting and RT-qPCR were used to …

If It Doesn't Hurt You Aren't Working Hard Enough: An Examination Of Coach Experience In High School Debate, Rosie Valdez Block

Student Theses and Dissertations

High school debate coaching constitutes a uniquely demanding educational role, defined by emotional labor, extended work hours, institutional precarity, and systemic inequities. Despite their significant contributions to students’ intellectual and personal growth, the professional sustainability of debate coaches remains underexamined. This dissertation investigates the conditions contributing to burnout among high school debate coaches through the theoretical lenses of Maslach’s Burnout Theory, as contemporized by Edú-Valsania et al. (2022), and teacher self-efficacy theory, to understand how emotional exhaustion, depersonalization, and diminished professional confidence emerge in this context. The study is further guided by constructivist grounded theory (Charmaz, 2014), enabling a bottom-up, …

Efficacy Evaluation Of An Allopathic & Homeopathic Anthelmintic On Small Ruminant Parasite Loads, Kennon Leigh Harrington

Cap1 (Cyclase-Associated Protein 1) Mediates The Camp Regulation Of Adhesion And Proliferation Of Schwann Cells In The Peripheral Nervous System, Jarna Karmoker

Student Theses and Dissertations

The peripheral nervous system relays signals between the central nervous system and the rest of the body, and peripheral nerve injuries and neuropathies can cause permanent neurological deficits. Schwann cells (SCs) are glial cells that myelinate neurons, which is essential for neuronal function and nerve repair. CAP1 (Cyclase-Associated Protein 1) is best characterized as an actin-regulating protein, while it also regulates other cellular processes, including matrix adhesion, migration, and proliferation. We discovered that cAMP-induced CAP1 dephosphorylation regulates relevant cell functions. While cAMP is also important for SC function and myelination, the underlying mechanisms remain largely unknown. We silenced CAP1 in …

American Sign Language Recognition And Analysis Using Deep Learning, Saurabh Kumar Soni

Master’s Dissertations

In this work I build a system that recognizes isolated American Sign Language (ASL) words, and I use it to ask one fairly direct question: when training data is scarce, is it better to look at the video pixels or at the geometry of the signer’s body? To find out, I train two very different models on exactly the same clips. The first is appearance-based. Every frame is run through standard preprocessing and a ResNet50 backbone pre-trained on ImageNet, which turns it into a 2048-dimensional feature vector, and a Bidirectional LSTM then reads that sequence over time. The second model …

An Empirical Study Of Rlvr Fine-Tuning For Mathematical Problem Solving In Llms, Rashmi Konnur

Master’s Dissertations

Large language models have shown immense improvement in coding and math performances thanks to reinforcement learning boosted algorithms. However, its true impact on broadening the reasoning and analytical capacities of an LLM is still contended. In this dissertation, we outline the foundations of Large Language Models, and delve into Reinforcement Learning with Verifiable Rewards (RLVR). We discuss various strategies to efficiently manipulate memory during a fine tuning update. We finally perform RLVR fine-tuning techniques on different models with varied use cases and compare their performances, which corroborate the efficiency of RLVR.

In Indonesia, lung cancer is the leading cause of death related to cancer, according to Global Cancer Observatory. Chemotherapy is the most common treatment since it works systemically and can prevent cancer cells from spreading to other organs. Cytotoxicity of chemotherapy can also put patients at high risk of experiencing adverse effects. This study aimed to evaluate the congruity of chemotherapy use with treatment recommendations and the profile of adverse effects, not only acute but also delayed adverse drug reactions. This prospective observational study involved 41 adult patients with lung cancer who received chemotherapy. Data is collected through patients’ medical …

Managing Virtual Work: An Integrative Framework For Human Resource Management, Tobias Blay, Fabian Jintae Froese, Sumita Raghuram, Bradford S. Bell, Agnes Bäker

Faculty Research, Scholarly, and Creative Activity

Virtual work has become a defining feature of contemporary organizations, yet Human Resource Management (HRM) scholarship lacks an integrated understanding of how it should be managed. We address this disconnect by shifting the focus from individual and team experiences to the organizational management of virtual work through HRM. We conceptualize virtual work and organize prior research along four dimensions: spatial, temporal, technological, and employment relationship. Building on this, we develop an integrative framework based on two axes, the degree of virtuality and the nature of the employment relationship, from which four forms of virtual work emerge and between which organizations …

A Portable Device To Elicit Sensory Trick And Monitor Forearm Muscle Activity In Pianists With Musician’S Dystonia, Josef Franczak

USF Tampa Graduate Theses and Dissertations

Musician’s Dystonia (MD) is a condition that can be acquired in professional musicians,causing involuntary contractions and the loss of fine motor control. The most common pharmaceutical treatment, botulinum toxin injections, has been shown to have side effects of muscle weakness and atrophy. The sensory trick, shown to temporarily relieve symptoms of dystonia, has potential to be used as an alternative or alongside current therapies, allowing patients with MD to return to playing music professionally. To systematically deploy the sensory trick and monitor forearm muscle activity, the first prototype of the Wearable Sensorimotor Integrator (wSMI) has been developed.

The wSMI is …

Age-related decline in oocyte quality increases the risk of infertility, miscarriage, and birth defects. Mitochondrial dysfunction is a key contributor to this decline. Here, we report that oocyte-specific deletion of Uba3, which encodes the catalytic subunit of the E1 NEDDylation-activating complex, causes sterility in mice. Fully grown, germinal vesicle–stage Uba3 conditional knockout oocytes exhibit mitochondrial dysfunction, including elevated reactive oxygen species, impaired oxidative phosphorylation, and depletion of mitochondrially encoded RNA transcripts. Proteomic analysis identified alterations in mitochondrial-associated proteins, including enrichment of mitochondrial matrix and respiratory chain components and reduced abundance of electron transport chain complexes. These defects were associated …

Conformational Cycling Of The Wntless Transporter Drives Trafficking And Secretion Of Wnt Morphogens, Yunhui Ge, Taciani De Almeida Magalhaes, Hongjiang Wu, Dick J H Van Den Boomen, Thu Uyen Nguyen, Tongyi Dou, Gaya P Yadav, Sukyeong Lee, Zhao Wang, Andrew Lemoff, Xuemei Luo, Sumitha S Menon, Min Zhang, Jin Wang, Zhicheng Jin, Jiansen Jiang, Adrian Salic, Pengxiang Huang

Faculty, Staff and Students Publications

Wnt proteins are lipid-modified morphogens fundamental in development and disease. During Wnt biogenesis, the G-protein-coupled receptor (GPCR)-like transporter Wntless (WLS) escorts lipidated Wnts from the endoplasmic reticulum to the plasma membrane, then transfers them to extracellular carriers, forming active and soluble morphogen-carrier complexes. To dissect the mechanisms involved, we solve cryo-EM structures of Wnt-bound WLS and unliganded WLS, and perform structure-guided functional experiments. Wnts engage WLS via three conserved hairpins, which are all required for Wnt trafficking to the cell surface and carrier-mediated secretion. Wnt release from cells is driven by dramatic conformational changes in the WLS transmembrane domain, reminiscent …

Where Diagnosis Meets Daily Life: Testing Theoretical Models Of Social Anxiety, Jessica A. Birg

USF Tampa Graduate Theses and Dissertations

Social anxiety disorder (SAD) is thought to persist through self-reinforcing cycles linking threat perception, fear of evaluation, avoidance, and social behavior. This dissertation examined whether the nature of these daily processes generalize across individuals, cluster into subgroups, or vary by social anxiety severity. Two ecological momentary assessment (EMA) studies were conducted: a community sample with and without SAD (Study 1: N = 96; five prompts per day across two 14-day bursts) and an undergraduate sample (Study 2: N = 129; six prompts per day across 14 days). Momentary variables included social anxiety, avoidance motivation, and threat and safety cues (hurt …

Using Phenomenology To Investigate Digital Experience: An Empathic-Somatic Approach, Bismark Wiafe Bimpong, William Kesse Bimpong, Mercy Egyir Kwakye

Mid-Western Educational Researcher

This conceptual paper proposes the Empathic-Somatic Approach as a methodological contribution for conducting phenomenological research on digital technology experiences. The Empathic-Somatic Approach does not replace existing phenomenological methods but enriches them by operationalizing the insight that we understand others through our own bodies as instruments of empathy. The paper first establishes the essential philosophical and methodological foundations of phenomenology needed to situate this contribution, then develops the Empathic-Somatic Approach in detail, and finally provides practical guidance for its implementation in digital technology research. This approach offers researchers in fields such as human-computer interaction, digital health, and information systems a principled …
