Chronic pruritus is defined as an itch lasting greater than six weeks. It can manifest from a wide variety of etiologies, as many different substances can act as pruritogens, such as steroids, histamine, progesterone, endogenous opioids, and serotonin. In the setting of cholestatic liver disease, increased bile acids play a major role in chronic pruritus. The itching in cholestatic liver disease is worsened in intensity at night and localized frequently to the palms, soles, knees, and other pressure sites. It can be hard to manage, affecting the quality of sleep and causing irritability, poor attention, and, in some cases, depression. …

The Role Of Oral Microbiota In Periodontitis And Alzheimer's Disease, Noah Al-Hassan, Taha Al Hassan, Juan C. Lopez-Alvarenga, Maria Quinones, Seratna Guadarrama

Research Symposium

Background: Periodontal disease (PD), affecting 20-50% of the global population is marked by biofilm-induced inflammation in oral tissues. Chronic PD results in systemic complications such as heart disease, stroke, and Alzheimer's. The red complex microbes, Porphyromonas gingivalis and Treponema denticola, play a pivotal role, penetrating the blood-brain barrier and contributing to neurodegeneration. Alzheimer's disease (AD), an irreversible neurodegenerative disorder, is linked to abnormal protein cleavage and potentially involves microbiologic components, including gram-positive cocci. Research suggests the presence of bacteria such as Porphyromonas, Actinomyces, and Treponema in autopsied AD brains. Investigating the microbiologic connection between PD and AD is crucial, considering …

Research Symposium

Background: The system's performance may be impacted by the high-dimensional feature dataset, attributed to redundant, non-informative, or irrelevant features, commonly referred to as noise. To mitigate inefficiency and suboptimal performance, our goal is to identify the optimal and minimal set of features capable of representing the entire dataset. Consequently, the Feature Selector (Fs) serves as an operator, transforming an m-dimensional feature set into an n-dimensional feature set. This process aims to generate a filtered dataset with reduced dimensions, enhancing the algorithm's efficiency.

Methods: This paper introduces an innovative feature selection approach utilizing a genetic algorithm with an ensemble crossover operation …


Reactive Oxygen Species In Acute Coronary Syndrome, Fernando Cisneros, Alex Zuo Mar 2024

Reactive Oxygen Species In Acute Coronary Syndrome, Fernando Cisneros, Alex Zuo

Research Symposium

Reactive oxygen species (ROS) are formed in metabolism, cellular signaling, immune response, antimicrobial defense, and detoxification. Oxidative damage through overproduction of ROS or dysregulation of ROS regulation may result in oxidative stress associated with DNA damage, protein damage, mitochondrial dysfunction, and lipid peroxidation. Additionally, the accumulation of dysfunction of cellular components may manifest as diseases that contribute to the predisposition of acute coronary syndrome (ACS). This poster meticulously explores the significance of ROS in various cardiovascular stressors, including hypertension, thrombogenesis, vascular remodeling, lipid peroxidation, cellular proliferation, atherogenesis, and vasoconstriction. These stressors collectively contribute to ACS associated with ischemia. Furthermore, autophagic …

Research Symposium

Introduction: Pancreatic Ductal Adenocarcinoma (PDAC) patients exhibit extremely poor prognosis. KRAS mutation on codon-12 is present in 70–95% of PDAC cases and it drives PDAC growth and progression. Galectin-1 (Gal-1) is present in both PDAC and stromal cells, being involved in tumor microenvironment, immune cell activation and metastasis. Therefore, this study discusses the efficiency of combined inhibition of mutated KRASG12D and Gal-1 inhibition to effectively suppress PDAC growth and progression. For this we have delivered KRASG12D inhibiting siRNA (siKRASG12D) using a superparamagnetic iron oxide nanoparticle (SPION) and a galectin inhibitor.

Methods: SPION nano-formulation was used to deliver siKRASG12D and investigate …

Research Symposium

Background: The composition of resident microbes in the human body is linked to various diseases and their treatment outcomes. Although studies have identified pancreatic ductal adenocarcinoma (PDAC) associated bacterial communities in the oral and gut samples, herein we hypothesize the prevalence of microbiota in pancreatic tumor tissues is different as compared to their matched adjacent, histologically normal appearing tissues and these microbial molecular signatures can be highly useful for PDAC diagnosis/prognosis.

Methods: In this study, we performed comparative profiling of bacterial populations in pancreatic tumors and their respective adjacent normal tissues using 16S rRNA-based metagenomics analysis.

Results: This study …

Faculty, Staff and Student Publications

Somatostatin (SST)-producing pancreatic delta-cells play an important role in maintaining the balance of insulin and glucagon secretion within the islets. This study aimed to generate a human embryonic stem cell (hESC) line with a SST-P2A-mCherry reporter using CRISPR/Cas9 system. The SST-P2A-mCherry reporter cell line was shown to maintain typical pluripotent characteristics and able to be induced into SST-producing pancreatic delta-cells. The generation of the cell line would provide useful platform for the characterization of stem cell-derived delta-cells, discovery of delta-cell surface markers and investigation of paracrine mechanisms, which will ultimately promote the drug discovery and cell therapy of diabetes mellitus.

We propose natural alkaloid berberine as a therapeutic with multitarget efficacy to alter mitochondrial metabolism and reprogram anaplastic thyroid cancer’s aggressive phenotype. Our in vitro model uses monocyte cell line U937, anaplastic thyroid cancer cell lines T238 …
