Pharmacy Faculty Articles and Research
Purpose Achieving successful gene therapy requires delivery of a gene vector specifically to the targeted tissue with efficient expression and a good safety profile. The objective of this work was to develop, characterize and determine if a novel gemini surfactant-based lipoplex systems, modified with a cancer-targeting peptide p18-4, could serve this role. Methods The targeting peptide p18-4 was either chemically coupled to a gemini surfactant backbone or physically co-formulated with the lipoplexes. The influence of targeting ligand and formulation strategies on essential physicochemical properties of the lipoplexes was evaluated by dynamic light scattering and small angle X-ray scattering techniques. In …
Gene Regulation In The Hypothalamic-Pituitary-Gonadal Axis Of The Green Anole Lizard (Anolis Carolinensis)., Joshua N. Peters
Gene Regulation In The Hypothalamic-Pituitary-Gonadal Axis Of The Green Anole Lizard (Anolis Carolinensis)., Joshua N. Peters
All Graduate Theses, Dissertations, and Other Capstone Projects
Studies examining the hypothalamic-pituitary-gonad axis (HPG) in Anolis carolinensis provide insight into the regulation of this axis under extremely different reproductive conditions. Molecular studies indicate that kisspeptin proteins, transcribed from kiss1 and kiss2 genes, are produced in the hypothalamus where they bind G protein-coupled receptor 54 (GPR54), activating the HPG axis. Gonadotropin inhibitory hormone (GnIH) and its receptors, G protein-coupled receptor 147 and 74 (GPR147 and GPR74), down regulate HPG axis function. In this experiment we examined HPG axis gene expression in the green anole lizard (Anolis carolinensis), a seasonally breeding species with higher steroid hormone levels in the breeding …

The purpose of this study was to explore the experience of creating a grassroots heroin awareness organization on a university campus through qualitative research. Various meeting types were attended as the grassroots efforts began: a student organization dedicated to the cause, the campus Alcohol and Other Drug Board, a local community treatment center agency, multiple University of Akron faculty members, and other heroin awareness groups in the community. Through observation and journaling of these meetings, I am sharing my experience based off analyzed field notes. After analyzation of these notes, common themes related to the formation of this kind of …
Functionalizing Titanium Implants With Bioactive Peptides To Increase Osseointegration, Neil Bernard
Functionalizing Titanium Implants With Bioactive Peptides To Increase Osseointegration, Neil Bernard
Williams Honors College, Honors Research Projects
Orthopedic surgeries have continued to increase, but the material of choice remains constant: titanium. Titanium has become the benchmark implant material due to its durability and non-immunogenic properties. However, while high rates of success are correlated with joint replacement surgery, certain patients with predisposed diseases such as diabetes or arthritis may have increased complications.1 This can be due to lack of osseointegration due to decreased bone formation and mineralization,2 which will lead to increased rates of infection or aseptic loosening of the implant from the bone. 3 Current methods to alleviate these complications include invasive revisional surgeries, which …

On The Efficacy Of High-Dose Ascorbic Acid As Anticancer Treatment: A Literature Survey, Florentin Smarandache, Victor Christianto
Branch Mathematics and Statistics Faculty and Staff Publications
Vitamin C (ascorbic acid, ascorbate) has a controversial history in cancer treatment. Emerging evidence indicates that ascorbate in cancer treatment deserves re-examination. As research results concerning ascorbate pharmacokinetics and its mechanisms of action against tumor cells have been published, and as evidence from case studies has continued to mount that ascorbate therapy could be effective if the right protocols were used, interest among physicians and scientists has increased.
Modulation Of Electron Transport By Metformin In Cardiac Protection: Role Of Complex I, Ahmed Abdul Hussein Mohsin
Modulation Of Electron Transport By Metformin In Cardiac Protection: Role Of Complex I, Ahmed Abdul Hussein Mohsin
Theses and Dissertations
Modulation of mitochondrial complex I during reperfusion reduces cardiac injury. Complex I exists in two structural states: active (A) and deactive (D) with transition from A→D during ischemia. Reperfusion reactivates D→A with an increase in ROS production. Metformin preserves the D-Form. Our aim was to study the contribution of maintenance of deactivation of complex I during early reperfusion by metformin to protect against ischemia reperfusion injury. Our results showed that metformin decreased H9c2 cardiomyoblast apoptosis and total cell death following simulated ischemia for six hours followed by reoxygenation for twenty four hours compared to untreated cells. Reactive oxygen species (ROS) …
Out-Of-Pocket Cost For Individuals Being Treated For Opioid Dependence In Rutland County, Vermont, Christopher T. Veal
Out-Of-Pocket Cost For Individuals Being Treated For Opioid Dependence In Rutland County, Vermont, Christopher T. Veal
Family Medicine Clerkship Student Projects
Each day more than 140 Americans die from drug overdoses, 91 specifically due to opioids. In Vermont, more than 50 people die each year from opioid poisoning. With insurance coverage being a critical component of Opioid Dependence Recovery, many people seeking treatment are unaware of the financial barriers to recovery- namely the out-of-pocket costs associated with treatment. This study sought to provide insight on the financial impact of Opioid Dependence Treatment on the patient, and provide financial assistance information to the Rutland County community.

In 1996, the state of California was the first in the union to allow for the use of medical marijuana. Since then, 28 more states have enacted similar laws (National Conference of State Legislatures, [NCSL], 2017). With the ever-growing opiate problem that has now been classified as an epidemic by the Centers for Disease Control and Prevention, medical marijuana could be a viable alternative to this problem.
As of 2014, the CDC reported opioid deaths were up 369%, which is more than 91 deaths per day from overdose (Centers for Disease Control, [CDC], 2017). The purpose of this study is …
Clearance Concepts: Fundamentals And Application To Pharmacokinetic Behavior Of Drugs, Reza Mehvar
Clearance Concepts: Fundamentals And Application To Pharmacokinetic Behavior Of Drugs, Reza Mehvar
Pharmacy Faculty Articles and Research
Clearance concepts were introduced into the pharmacokinetics discipline in the 1970s and since then have played a major role in characterization of the pharmacokinetic behavior of drugs. These concepts are based on the relationship between organ extraction ratio or clearance and physiologic parameters such as the organ blood flow and the intrinsic capability of the eliminating organ to remove the free (unbound) drug from the body. Several theoretical models have been developed, which define these relationships and may be used to predict the effects of changes in the physiological parameters on various pharmacokinetic parameters of drugs, such as drug clearance. …

The Association Of Hormonal Contraception With Depression, Pamela Derickson
The Association Of Hormonal Contraception With Depression, Pamela Derickson
Family Medicine Clerkship Student Projects
Hormonal contraceptives are widely used by women during their reproductive years. Currently, over 100 million women worldwide use the pill, and 82% of sexually active women in the USA will use oral contraceptive pills at some time during their reproductive years (Carrol, 2017). Oral contraceptive use, especially among adolescents, is associated with subsequent use of antidepressants and a first diagnosis of depression, suggesting depression may be a potential adverse effect of hormonal contraceptive use (Skovlund, 2016). This project focused on educating health care providers at the Community Health Center of Burlington, VT (CHCB) about the association of depression and oral …
Effect Of Energy Metabolism On Nf-Kb Activity In Ovarian Cancer, Simren K. Bagri
Effect Of Energy Metabolism On Nf-Kb Activity In Ovarian Cancer, Simren K. Bagri
Undergraduate Research Posters
NF-kB is a transcription factor involved in cancer cell growth and survival. The activation of NF-kB can be assessed by monitoring phosphorylation of RelA p65 at Ser-536, which is a surrogate of the NF-kB transcription factor activation. The objective of this study was to determine if the loss of ATP leads to NF-kB deficiency and thus, apoptotic cell death of “bad” cells in ovarian cancer cells. The independent variables were metformin (Met), an anti-diabetic medicine, another compound MinB functionally similar to Met and a glucose transporter inhibitor BAY-876. The dependent variables were the resulting effect of Met and MinB on …
Jwh-018 And Selective Serotonin Reuptake Inhibitors: Drug-Drug Interactions And Implications On Toxicity, Christopher O. Godwin
Jwh-018 And Selective Serotonin Reuptake Inhibitors: Drug-Drug Interactions And Implications On Toxicity, Christopher O. Godwin
Honors Theses
Drug abuse has expanded from more well-known substances, such as cocaine and marijuana, to relatively new novel psychoactive substances. A group of these substances called synthetic cannabinoids have been increasing in usage throughout the 2000's, and these compounds carry significant and varying risks depending on the dose and composition of the synthetic cannabinoid. Patients have been observed having symptoms associated with high doses of synthetic cannabinoids when they take lower doses of the synthetic cannabinoid in addition to their antidepressant medication. In order to test the effects of co-administration of selective serotonin reuptake inhibitors (SSRis) and synthetic cannabinoids, mice were …
Exploring Alternative Therapeutic Interventions For The Treatment Of Leigh Syndrome, Stephanie Martin
Exploring Alternative Therapeutic Interventions For The Treatment Of Leigh Syndrome, Stephanie Martin
Theses and Dissertations
Leigh syndrome is the most common mitochondrial disease, affecting 1:40,000 live births. It manifests with symptoms including ataxia, cognitive impairment, motor difficulties, and stroke. Leigh syndrome is a genetic condition caused by mutations in either the nuclear DNA or mitochondrial DNA that affects the assembly of the electron transport chains. Death typically occurs around 2-3 years of age, due to respiratory failure, as the body cannot produce sufficient ATP for survival. The genetic basis of Leigh syndrome means that there is no cure, and current treatments of the symptoms have proven ineffective. This thesis proposes two different therapeutic approaches for …

Regulation Of Prostaglandin D2 And Angiogenesis-Related Factors From Human Skin Mast Cells By Interleukin-6 And Resveratrol, Cody Cody Mchale
Theses and Dissertations
Mast cells are classically recognized as the effector cells of Immunoglobulin E (IgE)-mediated hypersensitivity reactions (i.e. allergic reactions). Mast cells also play an important role in the innate immune response to parasitic helminth infection. Allergic disease including allergic rhinitis, asthma, atopic dermatitis, and anaphylaxis, is a major health concern in the United States with greater than 60 million Americans suffering from allergy and asthma. In addition, mast cells have more recently been implicated in non-allergic disease including various human cancers, which will affect approximately 39.6% of U.S. men and women. Therefore, understanding the immunological and molecular mechanisms that regulate mast …

The goal of this investigation was to develop and demonstrate a polymer/paclitaxel self-assembly (PTX-SA) formulation. Polymer/PTX-SAs were screened based on smaller size of formulation using dynamic light scattering analysis. Additionally, fluorescence microscopy and flow cytometry studies exhibited that polyvinylpyrrolidone (PVP)-based PTX-SAs (PVP/PTX-SAs) had superior cellular internalization capability in MCF7 and MDA-MB-231 breast cancer cells. The optimized PVP/PTX-SAs exhibited less toxicity to human red blood cells indicating a suitable formulation for reducing systemic toxicity. The formation of PVP and PTX self-assemblies was confirmed using fluorescence quenching and transmission electron microscopy which indicated that the PVP/PTX-SAs were spherical in shape with an …

While the use of small molecule antibiotics has enabled many modern medical advances, it has also facilitated the development of resistant organisms. This minireview provides an overview of current small molecule drugs approved by the US Food and Drug Administration (FDA) for use in humans, the unintended consequences of antibiotic use, and the mechanisms that underlie the development of drug resistance. Promising new approaches and strategies to counter antibiotic-resistant bacteria with small molecules are highlighted. However, continued public investment in this area is critical …
Galantamine's Deconstruction In The Quest Of A Pam Pharmacophore, Malaika Argade
Galantamine's Deconstruction In The Quest Of A Pam Pharmacophore, Malaika Argade
Theses and Dissertations
Alzheimer’s disease is a progressive neurodegenerative disorder generally affecting people above the age of 65 years. Even though the pathophysiological hallmarks of AD were established more than a hundred years ago, there is yet to be a drug that can stop its characteristic neuronal damage. Of the five currently FDA-approved drugs, galantamine has a unique mechanism of action. Apart from being an AChE inhibitor, galantamine can effectively potentiate (positive allosteric modulator) the effect of agonists at nAChRs at concentrations lower than those required for its action as an AChE inhibitor. Perhaps the clinical benefits observed with galantamine are associated mainly …

The Role Of Ceramide In Neutrophil Elastase Induced Inflammation In The Lungs, Sophia Karandashova
Theses and Dissertations
Alterations to sphingolipid metabolism are associated with increased pulmonary inflammation, but the impact of inflammatory mediators, such as neutrophil elastase (NE), on airway sphingolipid homeostasis remains unknown. NE is a protease associated CF lung disease progression, and can be found in up to micromolar concentrations in patient airways. While sphingolipids have been investigated in the context of CF, the focus has been on loss of cystic fibrosis transmembrane conductance regulator (CFTR) function. Here, we present a novel observation: oropharyngeal aspiration of NE increases airway ceramides in mice. Using a previously characterized mouse model of NE-induced inflammation, we demonstrate that NE …

Viral gain-of-function mutations frequently evolve during laboratory experiments. Whether the specific mutations that evolve in the lab also evolve in nature and whether they have the same impact on evolution in the real world is unknown. We studied a model virus, bacteriophage λ, that repeatedly evolves to exploit a new host receptor under typical laboratory conditions. Here, we demonstrate that two residues of λ’s J protein are required for the new function. In natural λ variants, these amino acid sites are highly diverse and evolve at high rates. Insertions and deletions at these locations are associated with phylogenetic patterns indicative …
5-Ht2b Receptor-Mediated Cardiac Valvulopathy, Pallavi Nistala
5-Ht2b Receptor-Mediated Cardiac Valvulopathy, Pallavi Nistala
Theses and Dissertations
5-HT2B receptor agonism causes cardiac valvulopathy, a condition characterized by thickening of the heart valves and as a result, regurgitation of blood within the heart. The anti-obesity drug fenfluramine, which was originally prescribed as an anorectic, was withdrawn from the market due to causing cardiac valvulopathy. Fenfluramine, after metabolism by N-dealkylation, produces the metabolite norfenfluramine, which acts as a more potent valvulopathogen. The same was seen with MDMA (ecstasy), a popular drug of abuse, which is metabolized by N-dealkylation to produce MDA, a more potent valvulopathogen. Glennon and co-workers. studied a series of 2,5-dimethoxy-4- substituted phenylisopropylamines (DOX type) hallucinogens …
