Understanding Elements Involved In Active Racial And Ethnic Minority Recruitment Practices For Biopharmaceutical-Sponsored Clinical Trials: A Socio-Ecological Qualitative Inquiry, Rebecca Rae Johnson May 2020

Understanding Elements Involved In Active Racial And Ethnic Minority Recruitment Practices For Biopharmaceutical-Sponsored Clinical Trials: A Socio-Ecological Qualitative Inquiry, Rebecca Rae Johnson

Seton Hall University Dissertations and Theses (ETDs)

Inequitable participation in clinical trials continues to be a problem, and trial populations do not always reflect the demographics of the population that the investigational product will ultimately be treating. Because genetic differences between racial and ethnic groups affect the safety and efficacy of new treatments, it is important that standard of care decisions are made based on a representative population. The purpose of this study is to understand the socio-ecological elements that are involved in the active implementation of racial and ethnic minority recruitment practices for biopharmaceutical-funded trials in the United States. This general qualitative study was both descriptive …


Prediction Of Drug-Drug Interaction Potential Using Machine Learning Approaches, Joseph Scavetta May 2020

Prediction Of Drug-Drug Interaction Potential Using Machine Learning Approaches, Joseph Scavetta

Theses and Dissertations

Drug discovery is a long, expensive, and complex, yet crucial process for the benefit of society. Selecting potential drug candidates requires an understanding of how well a compound will perform at its task, and more importantly, how safe the compound will act in patients. A key safety insight is understanding a molecule's potential for drug-drug interactions. The metabolism of many drugs is mediated by members of the cytochrome P450 superfamily, notably, the CYP3A4 enzyme. Inhibition of these enzymes can alter the bioavailability of other drugs, potentially increasing their levels to toxic amounts. Four models were developed to predict CYP3A4 inhibition: …

Assessing The Effect Of Chronic Dopamine Receptor 2 Blockade As A Potential Model Of Secondary Negative Symptoms In Rats Using The Fr5/Chow Feeding Choice Task, Cyrene Nicholas

Honors Scholar Theses

Haloperidol, a dopamine (DA) D2 receptor antagonist, is an antipsychotic drug which is commonly used to treat schizophrenia and other psychiatric disorders. These disorders are often characterized by elevated striatal dopamine, which is speculated to have a role in producing positive symptoms such as hallucinations, delusions, and paranoia, as well as symptoms related to motivational salience and reward prediction. Individuals with schizophrenia also exhibit negative symptoms, such as amotivation, anergia, fatigue, and apathy among others. While some negative symptoms of schizophrenia are inherent to the pathophysiology, other negative symptoms are hypothesized to be partially induced by chronic exposure to antipsychotic …

Selective Autophagy Maintains The Aryl Hydrocarbon Receptor Levels In Hela Cells: A Mechanism That Is Dependent On The P23 Co-Chaperone, Yujie Yang, William K. Chan

School of Pharmacy Faculty Articles

The aryl hydrocarbon receptor (AHR) is an environmental sensing molecule which impacts diverse cellular functions such as immune responses, cell growth, respiratory function, and hematopoietic stem cell differentiation. It is widely accepted that the degradation of AHR by 26S proteasome occurs after ligand activation. Recently, we discovered that HeLa cells can modulate the AHR levels via protein degradation without exogenous treatment of a ligand, and this degradation is particularly apparent when the p23 content is down-regulated. Inhibition of autophagy by a chemical agent (such as chloroquine, bafilomycin A1, or 3-methyladenine) increases the AHR protein levels in HeLa cells whereas activation …

Commentary: Phytocannabinoids As Therapeutic Agents To Combat Chronic Gingival Disease., Nick Narek Ohanian

Pacific Journal of Health

The therapeutic potential of cannabis has been harnessed for thousands of years yet the United States Food and Drug Administration (FDA) has still not approved cannabis as a safe or effective drug. The FDA has, however, approved the manufacturing of pharmaceutical drugs, which contain a “synthetic version of a substance that is present in the marijuana” and other compounds that mimic its action. A search of the US National Library of Medicine and National Institute of Health for keywords “CBD” and “Periodontitis” together yields only 2 publications. Although the current State and Federal regulations on the use of cannabis for …

Ocular, Neural, And Cellular Biodistribution Of Multifunctional Antioxidants, Damian Daszynski May 2020

Ocular, Neural, And Cellular Biodistribution Of Multifunctional Antioxidants, Damian Daszynski

Theses & Dissertations

Aging is a complex biological process which stems from a growing imbalance between the regenerative capacity of an organism and endogenous as well as exogenous damaging factors. This imbalance leads to the slow deterioration of individual cells, organs, and eventually the entire organism. The free radical theory of aging combines the evolutionary and mechanistic aspects of aging, postulating that the innate process is caused by deleterious, irreversible, and inevitable changes in biological systems caused by oxidative damage that accumulates over the lifespan. Evidence of this phenomenon is supported by the pathogenesis of age-related diseases, such as age-related macular degeneration and …

Development Of Fluorescent Hyaluronic Acid Nanoparticles For Intraoperative Tumor Detection, Nicholas E. Wojtynek May 2020

Development Of Fluorescent Hyaluronic Acid Nanoparticles For Intraoperative Tumor Detection, Nicholas E. Wojtynek

Theses & Dissertations

Surgical resection remains to be the primary treatment for the majority of solid tumors, including breast cancer. The complete removal of the primary tumor, local metastases, and metastatic lymph nodes dramatically improve a patient’s treatment outcome and prognosis. Nevertheless, surgeons are limited to tactile and visual cues in distinguishing malignant and healthy tissue. This can result in a positive surgical margin (PSM), which occurs when tumor goes undetected and is left behind in the surgical cavity. PSMs decreases a patient’s prognosis and necessitate additional treatment in the form of surgery, radiation, and chemotherapy. An emerging imaging modality, known as fluorescence-guided …


Synthesis Of Fluorinated Pyrazoles Via Intra- And Intermolecular Cyclization Reactions, Matthew Saucier May 2020

Synthesis Of Fluorinated Pyrazoles Via Intra- And Intermolecular Cyclization Reactions, Matthew Saucier

Regulating Neuronal Growth With Structurally Defined Glycans, Gabriella D. Hartman May 2020

Regulating Neuronal Growth With Structurally Defined Glycans, Gabriella D. Hartman

Honors Theses

Chondroitin sulfate proteoglycans (CSPGs) and keratan sulfate proteoglycans (KSPGs) play an important role in neural development. Aggrecan, a CSPG, operates in the neural extracellular matrix where it negatively regulates neurite outgrowth to prevent aberrant process formation. Unfortunately, this aggrecan or CSPG-rich/KSPG-rich barrier can also prevent neuronal regeneration, which contributes to the inability to repair brain and spinal cord injuries. Removal of CSPGs and KSPGs has been shown to increase neurite outgrowth. We extend these findings by testing the ability of structurally-defined glycans to outcompete aggrecan and allow neurite outgrowth. Our overall goal is to determine if there is a particular …

Pharmacists can play a key role in preventing unintentional disqualifications of athletes as there are many medications considered performance enhancing drugs including some supplements and stimulants. For example, commonly used cold medications may contain pseudoephedrine hydrochloride, a banned substance in the world of …


Studies Of Salvinorin-Based Antagonists To Elucidate Pertinent Interactions For Kappa Opioid Receptor Antagonism, Madeline Keane May 2020

Studies Of Salvinorin-Based Antagonists To Elucidate Pertinent Interactions For Kappa Opioid Receptor Antagonism, Madeline Keane

Honors Theses

Opioid abuse, leading to addiction and related deaths, has created a chronic epidemic in the United States for the past 30 years. This crisis has sprung from reliance on the prescription of opioid analgesics as the primary method for the management of pain in the 1990s. At that time, these drugs, specifically Purdue Pharma’s OxyContin, were marketed as non-addictive. Due to this systemic minimization of the addictive properties of opioid analgesics, as prescription rates increased, opioid-related mortality rates climbed. This epidemic continues to be pervasive, as opioid-related overdose resulted in 47,600 deaths in 2017. In addition to the opioid epidemic, …

The Histone Deacetylase Inhibitor Largazole: A Potential Chemotherapeutic Agent, Hannah Lynn Carson

Honors Theses

Histone deacetylase enzymes are known for their inherent activity as epigenetic modifiers. Although, they have become recognized for their role in cancer progression and other diseases. But also, histone deacetylases have other non-histone targets, for example, microtubules, which play important roles in cancer metastasis, apoptosis, and replication. With histone deacetylase inhibitors (HDACi), our research explored HDACi effects on breast cancer cell lines. The overall goal was to understand the potential of largazole, a class one histone deacetylase inhibitor on breast cancer cell lines. The research consisted of two parts: sulforhodamine B (SRB) viability assays under hypoxic and normoxic conditions. The …


In-Vitro Assessment Of Cb1/Cb2 Receptor Binding And Function, Joey M. Davis May 2020

In-Vitro Assessment Of Cb1/Cb2 Receptor Binding And Function, Joey M. Davis

Honors Theses

Cannabinoid receptors CB1 and CB2 are G protein-coupled receptors that have a variety of physiological effects on the human body. Many natural product agonists and antagonists are presumed to interact with the cannabinoid receptors and are therefore heavily studied in drug discovery. Assays are used to study the binding of compounds to these receptors. However, a limited number of these assays are efficient in determining the functional activity of ligands associated with CB1 and CB2. Of those, many use radioactivity which is both expensive and potentially dangerous to the researcher. In this study, we first validated the assays already found …
