Antioxidant Activity And Phytochemical Profile Of Traditional Chinese Medicinal Plant Extracts, Ashley Tai

Senior Honors Projects

Traditional Chinese medicine (TCM), specifically the extracts of Chinese medicinal plants, has been studied for thousands of years to prevent, diagnose, and treat diseases. Our research group has initiated a program to systemically investigate the phytochemical composition and biological activities of a library of TCM medicinal plants. Herein, extracts of four commonly used TCM plants including broccoli (Brassica oleracea) seeds, horny goat weed (Epimedium brevicomu), houpu magnolia (Magnolia officinalis) bark, and golden root (Rhodiola rosea) were selected for this study. The antioxidant effects of these extracts were evaluated in a biochemical assay …

Cytochrome P450 1b1 And 12/15 Lipoxygenase Interaction In Paraventricular Nucleus In Angiotensin Ii-Induced Hypertension In Females, Shubha Ranjan Dutta

Theses and Dissertations (ETD)

Background: Angiotensin (Ang) II releases arachidonic acid (AA) from tissue phospholipids that is metabolized by 12/15-lipoxygenase (ALOX15) generating 12(S)- and 15(S)-hydroxyeicosatetraenoic acid (HETE) which have been implicated in cardiovascular and renal diseases. This study was conducted to investigate a) the contribution of ALOX15 to Ang II-induced hypertension and associated pathogenesis in female mice, and b) the interaction between the cytochrome P450 (CYP)1B1-generated metabolite of 17β-estradiol (E2) (2-methoxyestradiol, 2-ME) and ALOX15 in the paraventricular nucleus (PVN) as a mechanism that protects against Ang II-induced hypertension and its associated pathogenesis in female mice. Methods: Experiments were conducted in intact and ovariectomized (OVX) …

Accidental Extravasation Of Mitomycin C Into The Subcutaneous Tissue, Johnathon Chung, Brooke Walterscheid, Jose Lopez-Vera, Hytham Rashid, Mike K. Liang

HCA Healthcare Journal of Medicine

Introduction

Mitomycin C (MMC) is a common chemotherapeutic agent used to treat a variety of solid tumors. Cutaneous adverse events are rare, but MMC is a known vesicant reported to cause tissue necrosis and sloughing, erythema, and ulceration if incorrectly infused into the subcutaneous tissue. Definitive treatment of extravasation injuries due to MMC depends on the severity of the cutaneous manifestation, which includes stopping the infusion, removing the catheter, or possible debridement.

Case Presentation

We present the case of a 70-year-old female with extensive soft-tissue injury secondary to extravasation of MMC that required hospital admission and surgical intervention to remove …

Chewed Versus Swallowed Ticagrelor In P2y12 Inhibitor-Naïve Patients Undergoing Percutaneous Coronary Intervention, Thomas F. Wilson, Muddasir Ashraf, M. Fuad Jan, Tonga Nfor, Louie Kostopoulos, Joaquin Solis, Jayant Khitha, Ahmad Khraisat, Anthony C. Defranco, Tanvir Bajwa, Suhail Q. Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose: Dual antiplatelet therapy is standard for patients undergoing percutaneous coronary intervention (PCI) with stents. Traditionally, patients swallow the loading dose of a P2Y12 inhibitor before or during PCI. Time to achieve adequate platelet inhibition after swallowing the loading dose varies significantly. Chewed tablets may allow more rapid inhibition of platelet aggregation. However, data for this strategy in patients with stable ischemic heart disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) are less robust.

Methods: In this single-center prospective trial, 112 P2Y12-naïve patients with stable ischemic heart disease or NSTE-ACS on aspirin therapy and who received ticagrelor after coronary angiography but …

Accuracy Of Therapeutic Drug Monitoring In Vancomycin And The Pharmacist Role: A Retrospective Case-Series, Kateryna Parkhomenko

Senior Theses

Vancomycin is a mainstay of therapy for treating virulent and resistant infections, especially methicillin-resistant Staphylococcus aureus (MRSA). However, vancomycin requires therapeutic drug monitoring (TDM) for optimal dosing and treatment. This requires pharmacists to calculate a dosing regimen that correlates to appropriate goal vancomycin concentrations in the blood. Dosing vancomycin can be difficult, as it varies on a patient’s weight, renal function, age, etc. Doses may have to be adjusted in response to out-of-range concentrations, which requires further pharmacy calculations. Inaccurate dosing poses a risk to patient safety and places a resource and time burden on pharmacists. If vancomycin dosing methods …

Modulation Of Cerebral Artery Smooth Muscle Bk Channel Function By Neurosteroids, Kelsey Caroline Cleland North

Theses and Dissertations (ETD)

Voltage-gated and Ca2+ activated K+ channels of large conductance (BK) channels are essential for many key physiological processes, such as controlling the contraction of smooth muscle, including cerebrovascular smooth muscle. Importantly, BK channels are made up of a homotetramer of α subunits which associate with accessory β subunits. These β subunits alter the activity of the channel; this modulation is subunit-specific. Moreover, these accessory subunits have tissue-specific expression, such that the β1 subunit is highly expressed within cerebrovascular smooth muscle and greatly increases the open probability of BK channels. Increased BK channel open probability is linked to increased dilation of …

Preclinical Perspectives On The Mechanisms Underlying The Therapeutic Actions Of Psilocybin In Psychiatric Disorders, Andreas B. Wulff, Charles D. Nichols, Scott M. Thompson

School of Medicine Faculty Publications

Psychedelic compounds have shown extraordinary potential in treating a wide range of neuropsychiatric disorders. Psilocybin, for example, has now been shown in several clinical trials to induce a rapid (within days) and persistent (3–12 months) improvement in human treatment-resistant depression and other neuropsychiatric conditions. Here we review the preclinical models and experimental approaches that have been used to study the neurobiological actions of psychedelic drugs. We further summarize the insights these studies have provided into the possible mechanisms underlying the induction of their therapeutic actions, including the receptors to which psychedelics bind and the second messenger signaling cascades that they …

Induction Of Antimicrobial Protein S100a15 Expression By Oral Microbial Pathogens Is Toll-Like Receptors-Dependent Activation Of C-Jun-N-Terminal Kinase (Jnk), P38, And Nf-Κb Pathways, Denis Selimovic, Naji Kharouf, Florence Carrouel, Sofie Yasmin Hassan, Thomas W. Flanagan, Sarah Lilly Hassan, Mosaad Megahed, Youssef Haikel, Simeon Santourlidis, Mohamed Hassan

School of Medicine Faculty Publications

The antimicrobial protein S100A15 belongs to the S100 family, which is differentially expressed in a variety of normal and pathological tissues. Although the function of S100A15 protein has been discussed in several studies, its induction and regulation in oral mucosa, so far, are largely unknown. In this study, we demonstrate that S100A15 is induced by the stimulation of oral mucosa with gram− or gram+ bacterial pathogens, as well as with the purified membrane components, namely lipopolysaccharides (LPS) and lipoteichoic acid (LTA). The stimulation of the human gingival fibroblast (GF) and the human mouth epidermal carcinoma (KB) cell lines with either …

Intrinsic Programmed Death Ligand 1 (Pd-L1) Role In Promoting Triple Negative Breast Cancer (Tnbc) Progression, Duaa Salem Alkaabi

Theses

This thesis is concerned with Triple Negative Breast Cancer (TNBC), which is characterized by lack of estrogen, progesterone, and HER2 receptors expression, making targeted drugs ineffective. TNBC has a high proliferative rate, which results in a poor prognosis. Chemotherapy, the primary treatment for metastatic breast cancer, is not an ideal choice due to its toxicity towards normal cells. Therefore, Cancer-targeted therapy has been developed to improve the specificity and strength of the immune system against cancer cells. PD-L1 is an immunosuppressive protein that inactivates T cells by binding to the inhibitory receptor PD-1. The clinical use of PD-L1 blockade agents …

New Synthetic Opioids: Clinical Considerations And Dangers, Amber Edinoff, David Martinez Garza, Stephen Vining, Megan Vasterling, Eric Jackson, Kevin Murnane, Adam Kaye, Richard Fair, Yair Jose Lopez Torres, Ahmed Badr, Elyse Cornett, Alan Kaye

School of Medicine Faculty Publications

Since the early 2010s, synthetic opioids have significantly contributed to overall opioid-related overdose mortalities. For point of reference, of the 68,630 opioid-related deaths recorded in 2020, 56,516 involved synthetic opioids. During much of this period, fentanyl has been the most commonly used synthetic opioid. This time when fentanyl was the most popular opioid has been called the “third wave” of the opioid crisis, partly because it led to a sharp rise in deaths from overdoses. Other synthetic opioids, such as carfentanil, protonitazene, and isotonitazene, have also become more widely diverted for nonmedical used. Carfentanil is an even more potent fentanyl …

H2s, Sg-1002, Protects Against Myocardial Oxidative Damage And Hypertrophy In Vitro Via Induction Of Cystathionine Β-Synthase And Antioxidant Proteins, Rahib K. Islam, Erinn Donnelly, Erminia Donnarumma, Fokhrul Hossain, Jason D. Gardner, Kazi N. Islam

School of Medicine Faculty Publications

Endogenously produced hydrogen sulfide (H2S) is critical for cardiovascular homeostasis. Therapeutic strategies aimed at increasing H2S levels have proven cardioprotective in models of acute myocardial infarction (MI) and heart failure (HF). The present study was undertaken to investigate the effects of a novel H2S prodrug, SG-1002, on stress induced hypertrophic signaling in murine HL-1 cardiac muscle cells. Treatment of HL-1 cells with SG-1002 under serum starvation without or with H2O2 increased the levels of H2S, H2S producing enzyme, and cystathionine β-synthase (CBS), as well as antioxidant protein levels, such as super oxide dismutase1 (SOD1) and catalase, and additionally decreased oxidative …

Stress is associated with contextual memory deficits, which may mediate avoidance of trauma-associated contexts in posttraumatic stress disorder. These deficits may emerge from impaired pattern separation, the independent representation of similar experiences by the dentate gyrus-Cornu Ammonis 3 (DG-CA3) circuit of the dorsal hippocampus, which allows for appropriate behavioral responses to specific environmental stimuli. Neurogenesis in the DG is controlled by mitochondrial reactive oxygen species (ROS) production, and may contribute to pattern separation. In Experiment 1, we performed RNA sequencing of the dorsal hippocampus 16 days after stress in rats that either develop conditioned place avoidance to a predator urine-associated …

Intestinal Neuropod Cell Gucy2c Regulates Visceral Pain, Joshua R. Barton, Annie K. Londregran, Tyler D. Alexander, Ariana A. Entezari, Shely Bar-Ad, Lan Cheng, Angelo C. Lepore, Adam E. Snook, Manuel Covarrubias, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Visceral pain (VP) is a global problem with complex etiologies and limited therapeutic options. Guanylyl cyclase C (GUCY2C), an intestinal receptor producing cyclic GMP(cGMP), which regulates luminal fluid secretion, has emerged as a therapeutic target for VP. Indeed, FDA-approved GUCY2C agonists ameliorate VP in patients with chronic constipation syndromes, although analgesic mechanisms remain obscure. Here, we revealed that intestinal GUCY2C was selectively enriched in neuropod cells, a type of enteroendocrine cell that synapses with submucosal neurons in mice and humans. GUCY2Chi neuropod cells associated with cocultured dorsal root ganglia neurons and induced hyperexcitability, reducing the rheobase and increasing the resulting …

A Novel Sorbicillinoid Compound As A Potent Anti‐Inflammation Agent Through Inducing Nlrp3 Protein Degradation, Fangfang Wang, Youwei Zhang

Faculty Scholarship

Background and Purpose: Chronic inflammation is pathogenic and contributes to human diseases, causing a significant threat to public health. The NLR family pyrin domain‐containing protein 3 (NLRP3) is the best‐characterized factor regulating inflammation. Therefore, targeting NLRP3 has the potential to treat inflammatory diseases and improve human health. Experimental Approach: Lipopolysaccharide was used to induce inflammation in cell cultures. Lipopolysaccharide/d‐galactosamine and dextran sulfate sodium salt were used to induce acute liver inflammation and ulcerative colitis respectively in C57BL/6J mice. Western blotting, immunofluorescence, immunoprecipitation, quantitative PCR and enzyme‐linked immunosorbent assay (ELISA) were used to evaluate the activation of the inflammatory response in …

Machine Learning Methods For Computational Phenotyping Using Patient Healthcare Data With Noisy Labels, Praveen Kumar

Computer Science ETDs

Positive and Unlabeled (PU) learning problems abound in many real-world applications. In healthcare informatics, diagnosed patients are considered labeled positive for a specific disease, but being undiagnosed does not mean they can be labeled negative. PU learning can improve classification performance, and estimate the positive fraction, α, among unlabeled samples. However, algorithms based on the Selected Completely At Random (SCAR) assumption are inadequate when the SCAR assumption fails (e.g., severe cases overrepresented), and when class imbalance is substantial. This dissertation presents and evaluates new algorithms to overcome these limitations. The proposed methods outperform the state-of-art for α-estimation, enhance classification performance, …

Combination Sodium Nitrite And Hydralazine Therapy Attenuates Heart Failure With Preserved Ejection Fraction Severity In A “2-Hit” Murine Model, Kyle B. Lapenna, Zhen Li, Jake E. Doiron, Thomas E. Sharp, Huijing Xia, Karl Moles, Kashyap Koul, John S. Wang, David J. Polhemus, Traci T. Goodchild, Ravi B. Patel, Sanjiv J. Shah, David J. Lefer

BACKGROUND: Recent studies have suggested that cardiac nitrosative stress mediated by pathological overproduction of nitric oxide (NO) via inducible NO synthase (iNOS) contributes to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). Other studies have suggested that endothelial NO synthase (eNOS) dysfunction and attenuated NO bioavailability contribute to HFpEF morbidity and mortality. We sought to further investigate dysregulated NO signaling and to examine the effects of a NO-based dual therapy (sodium nitrite+hydralazine) following the onset of HFpEF using a “2-hit” murine model. METHODS AND RESULTS: Nine-week-old male C57BL/6 N mice (n=15 per group) were treated concurrently with high-fat …

Tris(1,3-Dichloro-2-Propyl) Phosphate Is A Metabolism-Disrupting Chemical In Male Mice, Sara Y. Ngo Tenlep, Megan L. Weaver, Jianzhong Chen, Olga A. Vsevolozhskaya, Andrew J. Morris, Cetewayo S. Rashid

Pharmacology and Nutritional Sciences Faculty Publications

Tris(1,3-dichloro-2-propyl) phosphate (TDCPP) is an organophosphate flame retardant. The primary TDCPP metabolite, bis(1,3-dichloro-2-propyl) phosphate (BDCPP), is detectable in the urine of over 90 % of Americans. Epidemiological studies show sex-specific associations between urinary BDCPP levels and metabolic syndrome, which is an established risk factor for type 2 diabetes, heart disease, and stroke. We used a mouse model to determine whether TDCPP exposure disrupts glucose homeostasis. Six-week old male and female C57BL/6J mice were given ad libitum access to diets containing vehicle (0.1 % DMSO) and TDCPP resulting in the following treatment groups: 0 mg/kg/day, 0.02 mg/kg/day, 1 mg/kg/day, or 100 …

Effects Of Disulfiram On The Metabolome Of Mrsa, Surya Teja Naidu

Theses, Dissertations and Capstones

Disulfiram, known as Antabuse®, is an oral drug for the treatment of alcohol dependence. Previous studies have indicated that disulfiram (DSF) exhibits antibacterial effects, particularly against Gram-positive bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA). Our study delves into the antibacterial mechanism of DSF in MRSA through High-Pressure Liquid Chromatography (HPLC) metabolomics, investigating the underlying mechanism of DSF effects on thiamine and amino acid metabolism. Thiamine pyrophosphate (TPP) plays a crucial role as a cofactor for critical enzymes such as transketolase, pyruvate dehydrogenase, and 2-oxoglutarate dehydrogenase. These enzymes are integral to the carbohydrate metabolism process within bacterial cells. TPP also contributes …

High Body Mass Index Changes Peri-Tumor Adipose Tissue Which In Turn Promotes Triple Negative Breast Cancer, Cora Elizabeth Miracle

Theses, Dissertations and Capstones

Cancer is one of the leading causes of death worldwide, responsible for over half a million deaths each year. There are multiple risk factors associated with the development of cancer. Some of these risks include genetics, smoking, and most recently, obesity (Lewandowska et al., 2019) (De Pergola & Silvestris, 2013). Research has shown that obesity is linked to the promotion of fourteen different cancers, including aggressive triple negative breast cancer (TNBC). Patients that are obese are more likely to develop cancer (Park et al., 2014). In addition, if the patient is obese at the time of a cancer diagnosis, they …

Prenatal Buprenorphine Exposure Reduces Expression Of Myelin Proteins In Neonatal Longs-Evans Rat, Christopher James Grahe

Theses, Dissertations and Capstones

In the USA and especially in WV, there has been a surge in the rise of opioid use disorder (OUD), and with it a rise in neonatal abstinence syndrome (NAS). What makes this rise in NAS so unfortunate is that the Medications for OUD (MOUD) do not prevent the development of NAS. Although the relationship between MOUD and NAS is still unclear, it is thought that buprenorphine, one of the main substances used to treat OUD in pregnant women, may feed into the development of NAS, which may affect mental and physiological development and cause other health problems. Via understanding …

Role Of Histone Deacetylase (Hdac) In Epithelial To Mesenchymal Transition (Emt) In A Human Cholangiocyte Model Of Ischemic Cholangiopathy, Priyanshi Pragnesh Parikh

Theses and Dissertations

Organ transplants are a vital intervention for many diseases that result in end stage organ failure. Currently, the donation pool is not meeting the demands of the transplant list. Expanding this pool to include donation after cardiac death (DCD) is highly sought-after. However, the use of DCD livers can lead to increased odds of graft failure and ischemic cholangiopathy. The loss of epithelialization and fibrosis that occurs during ischemic cholangiopathy is characteristic of these cells undergoing epithelial-to-mesenchymal transition (EMT). The biological changes the cell experiences enhance migratory capacity, invasiveness, and increased resistance to apoptosis. Our earlier studies have shown differential …

Characterizing The Effects Of Antiandrogens And Senolytics To Enhance The Therapeutic Response To Castration-Resistant Prostate Cancer, Justin M. Silverman

Theses and Dissertations

Prostate cancer is the most frequently diagnosed cancer in males and the second most common cause of cancer deaths. Androgen deprivation therapy, whether through surgical or chemical castration, is the mainstay for treatment of advanced prostate cancer; however, despite an initial response, most patients eventually develop a progressive PSA rise, and castration- sensitive prostate cancer gives rise to castration-resistant prostate cancer. The standard of care therapy includes the antiandrogens such as enzalutamide and abiraterone acetate as well as the microtubule poison, docetaxel, and various immunotherapies; however, while prostate cancer research is progressing, there continues to be a compelling need for …

Development Of A Chemical Biology Approach To Uncover The Influence Of Sequence Variations On Ces1 Activity In Live Cells, Samuel James Knebel

Masters Theses

Drug metabolism is the biochemical process of modifying drugs to detoxify and remove them through enzymatic transformations. These biotransformation’s occur primarily in the liver and are critical to understanding how pharmaceutical compounds are chemically altered inside the human body. Human carboxylesterases (CESs) catalyze the hydrolysis of esters, amides, thioesters, and carbamates. CES-mediated hydrolysis plays an important role in the metabolism of many drugs including the first FDA approved antiviral treatment for COVID-19, remdesivir (Veklury), the seizure control medication rufinamide (Banzel), and the flu antiviral drug oseltamivir (Tamiflu). CES activity is known to be influenced by a variety of factors including …

Small extracellular vesicles are nanosized vesicles (30-200 nm) that can ferry proteins, nucleic acids, and lipids between cells and therefore, have significant potential as biomarkers, drug delivery tools or therapeutic agents. SEVs of endothelial origin have been shown to -among other functions-reduce in vitro ischemia/reperfusion (I/R) injury in cardiomyocytes, but whether a pro-inflammatory state of the endothelium impairs the functionality of these SEVs remains to be elucidated. To test this, human umbilical vein endothelial cells cells were treated with TNF-α 10 ng/mL and the expression of the pro-inflammatory parameters VCAM-1, ICAM-1 and eNOS were determined by Western blot. SEVs were …
