Qat (Catha edulis) chewing is a common practice in Yemen, associated with oral mucosal irritation. The objective of the current study is to compare cytological findings of buccal mucosa between Qat chewers and non-chewers. A comparative cross-sectional study was designed. Buccal smears were collected from chewers (n = 100) and non-chewers (n = 100), fixed, and stained with Harris hematoxylin staining. Smears were assessed for inflammatory changes and cytological atypia by two blinded examiners; disagreements were resolved by consensus. The inflammatory cells were observed in 21% of chewers compared to 8% of controls (P = 0.009), while …

Faculty, Staff and Student Publications

Background: Epithelial cell adhesion molecule (EpCAM) is a pleotropic transmembrane glycoprotein comprising an extracellular domain (EpEX), a single transmembrane domain, and an intracellular domain (EpICD). For several types of cancer, high EpCAM expression is associated with tumor progression, metastasis, immune evasion, and overall poor prognosis. A rare but aggressive form of thyroid cancer, anaplastic thyroid cancer (ATC), has a mean survival time of only 3–6 months after diagnosis.

Methods: The levels of EpEX and EpICD cleavage in clinical patient samples was evaluated by using tissue microarray. Capture enzyme-linked immunosorbent assay (ELISA) was conducted to explore the of shedding EpEX and …

Energetics And Kinetics Of Alkali Ion Exchange In Analcime, Jinyi Liu, An T. Ta, R. Seaton Ullberg, Jean Wilfried Hounfodji, Michael Badawi, Hans Conrad Zur Loye, Simon R. Phillpot

Faculty Publications

We employ density functional theory calculations to investigate the energetics and diffusion mechanisms of alkali metal ions (Na⁺, K⁺, Rb⁺, and Cs⁺) within the analcime framework. While Na⁺preferentially adsorbs at the center of the 8-member ring, DFT calculations show that larger ions, such as Cs⁺, occupy the center of the cage due to steric constraints. The computed exchange energies indicate that exchange of Na⁺by Cs⁺is thermodynamically favorable. Migration energy barriers, determined using the climbing image nudged elastic band method, show that Na⁺is …

Multiplex immunofluorescence and immunohistochemistry (mIF/IHC) are increasingly employed antibody-based technologies that use tissue sparingly and facilitate the detection of co-localized or neighboring biomarkers. Specifically, these platforms enable spatial analyses of the tumor microenvironment as well as extended applications, for example, describing normal tissue anatomy, autoimmunity, infectious diseases, etc. mIF/IHC has greatly enhanced biomarker discovery efforts, and a growing number of studies suggest superiority to traditional IHC. Standardization of staining approaches, reporting of image analysis strategies and resultant data is critical for facilitating cross-study comparisons, validation, deployment, and generalization of findings. To address this challenge, The Society for Immunotherapy of Cancer …

Chaos Engineering In Multi-Gigahertz Solid-State Lasers: A Novel Approach To Optoelectronic Control, Mikhail V. Gorbunkov, Yulia Ya. Maslova, Yulia A. Sinichkina

Karbala International Journal of Modern Science

This paper presents a comprehensive study of a multi-gigahertz chaotic generator of light pulses based on solid-state laser sources, including fiber lasers, governed by carefully designed positive and negative feedback loops. It harnesses the inherent nonlinear dynamics within a solid-state laser controlled by a combination of two inertial feedback loops, enabling the realization of complex chaotic behavior, including the logistic map scenario, under moderate amplification conditions. The laser system dynamics are rigorously investigated through theoretical modeling, employing a nonlinear map approach, and high-resolution picosecond simulations. The results of our numerical simulations highlight the efficacy of fast electro-optical feedback system with …

Syzygium cumini is plant that extensively used in cuisine and traditional medicine. However, its potential for NSCLC treatment has not yet been elucidated. This study determined the potential of S. cumini as anti-NSCLC using in silico approaches. The in silico study was applied to perform active compound analysis, selection of target candidates, network pharmacology, functional annotation, molecular docking, and molecular dynamics simulation, respectively. Based on open source databases, S. cumini contained 115 compounds and 14 of them predicted to have …

Trait-Like Visual Cortical Hyperactivity In Trait Anxiety, Zhaohan Wu, Yuqi You, Joshua A Brown, Raymond J Dolan, Wen Li

Faculty, Staff and Student Publications

Sensory processing varies across individuals, with some traits-particularly sensory hypersensitivity to basic non-valenced stimuli-linked to emotional traits and psychiatric risk. Traditional accounts attribute this sensory-emotion linkage to limbic or prefrontal modulation, but empirical support is limited. Growing evidence suggests sensory cortex itself flexibly encodes value beyond labeled-line analysis. Across four high-density EEG experiments with multi-wave assessments, we identified reliable visual cortical hyperactivity in high trait anxiety. The effect emerged as early as 46 ms, localized to V1/V2, and was specific to the parvocellular pathway. It was reproducible across arousal states, stimulus valence, extended intervals, and paradigms, and evident for both …

A Comparison Of White-Light And Monochromatic Led Sources For Antimicrobial Photodynamic Inactivation Of Staphylococcus Aureus, Emily Simmons

The Journal of Purdue Undergraduate Research

Drug-resistant bacteria are an ongoing public health crisis for which alternative treatments are needed. One alternative is antimicrobial photodynamic inactivation (aPDI), which uses potent photosensitizers and light irradiation to damage the bacteria. Our standard light source used in aPDI is a single-wavelength light source at 405-nm; however, we evaluated a white-light source for similarities in the resulting aPDI activities. This is done by comparing aPDI experiments using S. aureus and its methicillin-resistant strains (MRSA) conducted with either the white LED light source or the 405-nm LED light source. Statistical analysis using t-tests revealed no significant differences in the aPDI activities …

Just "Beet" It? A Comparison Of Road Salt Effects On The Life History Of Daphnia Magna, Koby Sellner

The Journal of Purdue Undergraduate Research

In areas that experience snow and ice, deicing reagents such as road salts are often used on roads to promote safer driving conditions. However, road salts run off into local vegetation, soil systems, and (my focus) freshwater systems. The impacts of excess salt and chloride in freshwater have been studied extensively on a broad diversity of organisms under different conditions, but previous studies have rarely used different types of road salts. Zooplankton are primary consumers in many freshwater systems, feeding on phytoplankton and serving as prey for predator species higher in the trophic chain. These animals generally are impacted negatively …

Effects Of Alcohol Exposure On Recognition Memory And Marble-Burying Tasks In Male And Female Aged Mice, Roma Kamat, Tori Burke

The Journal of Purdue Undergraduate Research

Alcohol consumption in aging humans is a risk factor for cognitive impairment. This experiment assessed the effects of binge-like alcohol drinking in aged mice on memory (using the object recognition memory [ORM] task) and on anxiety-and compulsive-like behavior (using the marble-burying task). Subjects were 8 female and 10 male mice, 14–15 months old, selectively bred for low alcohol preference (LAP). Mice consumed either tap water or a 20% alcohol (v/v) solution in tap water through a drinking in the dark (DID) procedure for 4 consecutive days per week, for 3 consecutive weeks. One and 11 days after DID, mice completed …

Immunohistochemical Analysis Of The Effects Of Streptozotocin-Induced Diabetes On Mouse Testis, Rory E. Field, Brianna R. Demaio, Hannah R. Fioramonti, Makenna M. Landis, Jing Xu

Montview Journal of Research & Scholarship

Because diabetes mellitus (DM) poses harm to the reproductive systems of humans and mice on both the cellular and histological levels, we sought to understand the effects of streptozotocin-induced (STZ) diabetes mellitus on the spermatogenesis and Anti-Müllerian hormone (AMH) production of mice. The structural integrity of the testes is disrupted due to the high levels of oxidative stress caused by DM, which also hinders spermatogenesis. Advanced glycation end products (AGEs) have been found to induce autophagy in Sertoli cells, and the Sertoli cells of diabetic models have fewer tight junctions between them. This disorganization and decreased integrity of the seminiferous …

Substantial Contribution Of Woody Components To Rainfall Interception In Chinese Forests: Insights From A Refined Analytical Model, Zhi-Ang Chen, Zhi-Yun Jiang, Wei He, John T. Van Stan Ii, Et. Al.

Biological, Geological, and Environmental Faculty Publications

Assessing rainfall interception (I-R) is a critical yet uncertain aspect in hydrological cycle, particularly the quantification of relative contributions from leaves and woody components (e.g., branches, stems, and trunks) to I-R. Nevertheless, the role of woody components in I-R estimation remains largely unexplored and thereby has been constantly overlooked. This study addressed this challenge and refined the widely-used Gash model to distinguish woody interception (I-W) from leaf interception (I-L). We incorporated the spatial variability of vegetation traits alongside satellite data in 2019 into the refined model, and spanned China's major forest types. The refined model showed a strong agreement with …

Development Of Self-Assembled Polymeric Polyplexes For Microrna Delivery: Toward Treatment Of Alcohol-Associated Liver Disease, Marjina Akter Kalpana

Theses & Dissertations

Self-assembled polymeric polyplexes have the potential to serve as an RNA interference (RNAi) delivery platform for the combined inhibition of CXCR4 and miR-155 in the treatment of alcohol-associated liver disease (AALD). A central challenge in RNA delivery is balancing the extracellular stability of polyplexes, cellular uptake, and intracellular release of RNA cargo. We developed polymeric polyplexes using the CXCR4-antagonist polymer PAMD, designed to target CXCR4 on activated hepatic stellate cells (HSCs) and deliver therapeutic miRNA to activated Kupffer cells (KCs) in fibrotic liver. We improved the polyplexes by cholesterol modification of PAMD and by PEGylation of PAMD-Ch. The cholesterol modification …

Mechanistic Insight Of Neuropilin-2 Expression During The Progression Of Prostate Cancer, Sanika Bodas

Theses & Dissertations

Advanced prostate cancer represents a particularly aggressive and challenging form of prostate cancer (PCa) that shows resistance to both traditional therapies, such as androgen deprivation therapy, and newer treatment modalities like hormone therapies and immunotherapies. For patients diagnosed with advanced stages of PCa, treatment options are limited, and chemotherapy is often the last line of defense. Unfortunately, chemotherapy can severely diminish the quality of life, particularly in older patients, due to its harsh side effects, including fatigue, immune suppression, and overall physical decline. Despite these challenges, researchers and clinicians remain focused on developing more effective and targeted treatments for patients …

Evaluating Bmx-001 As A Selective Radioprotector For Healthy Tissue In Pelvic Cancers, Molly Myers

Theses & Dissertations

Pelvic cancers, including rectal, anal, and prostate cancer, are relatively survivable cancers with high five-year survival rates, partially due to the addition of radiation to treatment regimens. Radiation confers excellent tumor control, but also causes damage to surrounding tissue, resulting in both short-term and long-term side effects. In a patient population that is surviving longer after treatment, limiting the impact of side effects is instrumental to improving patient quality of life. Radiation-induced ROS is instrumental in causing these side effects and provides a unique opportunity to protect healthy tissue from damage while sensitizing cancer tissue to treatment, as cancer cells …

Role Of Nadph Oxidase 4 In Murine Cancer-Associated Fibroblast, Faith M. Gomez

Theses & Dissertations

Breast cancer is the second leading cause of cancer deaths in women in the United States. Frontline hormone therapies for breast cancer prove ineffective in triple negative breast cancer tumors wherein the hormones estrogen, progesterone, and HER2 are downregulated or absent; therefore, patients diagnosed with triple negative breast cancer are primarily limited to chemotherapies which carry a higher failure and resistance rate. Here we target cancer associated fibroblasts as potential drivers of chemoresistance in triple negative breast cancer. We investigated the mechanism by which Nox4 regulates the YAP/TAZ pathway in modulating DTX sensitivity and sought to determine if targeting Nox4 …

Immunoglobulin Germline Reference Sequences Enable Investigations And Reveal Insights Into Bat-Specific Immunity, Ashley B. Reers, Shijun Zhan, Taylor Pursell, Clara Reasoner, Natasha Hodges, Tanya M. Lama, Tony Schountz, Hannah K. Frank

Biological Sciences: Faculty Publications

We generated a highly contiguous, annotated genome of the Jamaican fruit bat, Artibeus jamaicensis, including annotated germline immunoglobulin heavy-chain (IGH) and light-chain lambda (IGL) loci to understand bat B cell receptor repertoires. The bat germline shares many structures and features described in human immunoglobulin loci. However, some features are unique to A. jamaicensis, including an expansion of cysteine-rich IGHV genes. To investigate the relationship between the germline IGH locus and expressed B cell receptors (BCRs), we sequenced the BCRs of wild-caught and captive A. jamaicensis, finding an enrichment of IGHV3 and IGHV4 genes. Compared to humans, A. jamaicensis had shorter …

Biology Theses, Dissertations, and Student Creative Activity

The COVID-19 pandemic created a shift in the trajectory of vaccination hesitancy, altering risk perceptions and vaccination attitudes among individuals in rural communities. The 5C framework highlights confidence, complacency, constraints, calculation, and collective responsibility as influencing factors of vaccine hesitancy. This study assessed the proportion of adults who refused COVID-19 vaccination and identified the individual reasons for hesitancy among those who refused the COVID -19 vaccines in South Central Nebraska. Data was analyzed from a local cross-sectional public health survey administered to 2,034 adult participants over a six-month period (March-August 2024), including 91 respondents who were from outside the seven-county …

Comparisons Of Fish Communities Between A Restored And A Control Pool Of The Mississippi River: A Before-And-After Examination, Hannah Lenning

Biology Theses, Dissertations, and Student Creative Activity

The quality and availability of valuable backwater habitats have declined in many rivers, including the Upper Mississippi River (UMR), due to river modifications and land use change. Habitat Rehabilitation and Enhancement Projects (HREPs) are implemented by the Upper Mississippi River Restoration Program and often aim to mitigate accelerated sedimentation and degradation of backwater habitats. One HREP in Pool 12 of the UMR targeted overwintering fish habitat by restoring four backwaters within 14 RKM. Fish community data was collected before (2006-2012) and after (2020-2024) restoration in Pool 12 and a downstream, control reach, Pool 13. The first objective of my study …
