Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …

Analyzing The Effectiviness Of A Prescription Drug Monitoring Program Targeting At-Risk Opioid Abuse Patients, Treadway Childs

Public Administration ETDs

The effectiveness of a prescription drug monitoring program in coordination with a prescription opioid recidivism program was examined at a semi-rural community hospital. Patients were identified by a multi-disciplinary committee to be at-risk for opioid misuse or abuse, and were denied prescription opioids. Patients were considered eligible for the program if they had over 12 emergency department visits in the previous 12 months, or 6 visits in the previous 6 months, depending on how long the hospital had records on a patient. Patients who were placed in the prescription opioid recidivism program could not receive opioids at this hospital. The …

Computational Drug Design: A Multitargeted Approach In Bladder Cancer, Travis C. Lantz, Joydeb Majumder, Gaurav Chopra

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cancer is a complex, robust disease with multiple redundant disease pathways which lead to tumor development, growth, and eventually even death. Despite known redundancies, cancer therapeutics continue to be developed against a single protein target. Initial disease regression occurs followed by relapse in a drug resistant disease state. In response, combinational drug clinical trial targeting multiple pathways began, and have failed due to increased toxicity caused by adverse drug interactions. Development of a single drug that differentially targets multiple disease pathways will result in a more potent therapeutic while inducing minimal toxicity. This was done computationally through in-lab software packages, …

Tumor-Targeted Delivery Of Sirna Using Fatty Acyl-Cgkrk Peptide Conjugates, Meenakshi Sharma, Naglaa Salem El-Sayed, Hung Do, Keykavous Parang, Rakesh Tiwari, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Tumor-targeted carriers provide efficient delivery of chemotherapeutic agents to tumor tissue. CGKRK is one of the well-known tumor targeting peptides with significant specificity for angiogenic blood vessels and tumor cells. Here, we designed fatty acyl conjugated CGKRK peptides, based on the hypothesis that hydrophobically-modified CGKRK peptide could enhance cellular permeation and delivery of siRNA targeted to tumor cells for effective silencing of selected proteins. We synthesized six fatty acyl-peptide conjugates, using a diverse chain of saturated and unsaturated fatty acids to study the efficiency of this approach. At peptide:siRNA weight/weight ratio of 10:1 (N/P ≈ 13.6), almost all the peptides …

Antimicrobial Hydroxyapatite-Gelatin-Silica Composite Pastes With Tunable Setting Properties, Vuk Uskoković, Shreya Ghosh, Victoria M. Wu

Pharmacy Faculty Articles and Research

Bone grafting is one of the commonest surgical procedures, yet all bone substitutes developed so far suffer from specific weaknesses and the search for a bone graft material with ideal physical and biological properties is still ongoing. Calcium phosphate pastes are the most frequently used synthetic bone grafts, yet they (a) often take an impractically long time to set, (b) release the drug content too fast, and (c) do not form pores large enough to accommodate host cells and foster osseointegration. To make up for these deficiencies, we introduced gelatin and silica to pastes composed of 5–15 nm sized hydroxyapatite …

Synthesis And Evaluation Of Antimicrobial Activity Of [R4w4k]-Levofloxacin And [R4w4k]-Levofloxacin-Q Conjugates, Neda Riahifard, Kathy Tavakoli, Jason Yamaki, Keykavous Parang, Rakesh Tiwari

Pharmacy Faculty Articles and Research

The development of a new class of antibiotics to fight bacterial resistance is a time-consuming effort associated with high-cost and commercial risks. Thus, modification, conjugation or combination of existing antibiotics to enhance their efficacy is a suitable strategy. We have previously reported that the amphiphilic cyclic peptide [R4W4] had antibacterial activity with a minimum inhibitory concentration (MIC) of 2.97 g/mL against Methicillin-resistant Staphylococcus aureus (MRSA). Herein, we hypothesized that conjugation or combination of the amphiphilic cyclic peptide [R4W4] with levofloxacin or levofloxacin-Q could improve the antibacterial activity of levofloxacin and levofloxacin-Q. Fmoc/tBu solid-phase chemistry was employed to synthesize conjugates of …

Effects Of Phosphodiesterase 3a Modulation On Murine Cerebral Microhemorrhages, Rachita K. Sumbria, Vitaly Vasilevko, Mher Mahoney Grigoryan, Annlia Paganini-Hill, Ronald Kim, David H. Cribbs, Mark J. Fisher

Pharmacy Faculty Articles and Research

Background: Cerebral microbleeds (CMB) are MRI-demonstrable cerebral microhemorrhages (CMH) which commonly coexist with ischemic stroke. This creates a challenging therapeutic milieu, and a strategy that simultaneously protects the vessel wall and provides anti-thrombotic activity is an attractive potential approach. Phosphodiesterase 3A (PDE3A) inhibition is known to provide cerebral vessel wall protection combined with anti-thrombotic effects. As an initial step in the development of a therapy that simultaneously treats CMB and ischemic stroke, we hypothesized that inhibition of the PDE3A pathway is protective against CMH development.

Methods: The effect of PDE3A pathway inhibition was studied in the inflammation-induced and …

A Descriptive Study Of The Elderly In California Substance Abuse Treatment Programs, David Berenschot

Electronic Theses, Projects, and Dissertations

As gerontologists may know, there are a great deal of studies and a variety of academic literature on the misuse of alcohol and prescription medication amongst the elderly population. While there is a plethora of information on alcohol and prescription misuse, there is little reported data about the prevalence of other substance misuse experienced by this population. This study aims to help to fill that gap in the data by using quantitative methods to describe the scope of substance abuse of individuals 55-years or older. This study utilizes data from the Treatment Data Set Admission (TEDS-A). The TEDS-A is a …

Detection Of Cathinone And Mephedrone In Plasma By Lc-Ms/Ms Using Standard Addition Quantification Technique, Theron W. Ng-A-Qui

Student Theses

Designer drugs are structural analogs of Drug Enforcement Agency (DEA) Schedule I and II substances. They are synthesized to mimic the effects of illegal drugs of abuse and to bypass the provisions of drug regulations. Despite the increased availability of designer drugs, few studies have focused on specific analytical extraction techniques for their detection and quantification in biological samples. Solid phase extraction (SPE) is the most commonly used technique for sample preparation. The purpose of this study is to evaluate the extraction efficiency of the various SPE columns with different sorbent materials for two designer drugs, cathinone and mephedrone in …

Tumor Necrosis Factor Α Inhibition For Alzheimer's Disease, Rudy Chang, Kei-Lwun Yee, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Tumor necrosis factor α (TNF-α) plays a central role in the pathophysiology of Alzheimer’s disease (AD). Food and Drug Administration–approved biologic TNF-α inhibitors are thus a potential treatment for AD, but they do not cross the blood-brain barrier. In this short review, we discuss the involvement of TNF-α in AD, challenges associated with the development of existing biologic TNF-α inhibitors for AD, and potential therapeutic strategies for targeting TNF-α for AD therapy.

Polymers with high molecular weight and water solubility were chosen for further modification into folate-functionalized polymeric nanoparticles for targeted drug delivery to cancer cells. This was achieved by employing a solvent diffusion method, wherein the polymer …

Structure Activity Relationship Studies Of Novel Diarylpentanoid Analogs Targeting The Androgen Receptor In Prostate Cancer Cells, Haili Coffin, Marco Bisoffi

Student Scholar Symposium Abstracts and Posters

The development of prostate cancer (PCa) relies strongly on the activation of the androgen receptor (AR) signaling pathway by its natural ligand dihydrotestosterone. Furthermore, PCa progression to metastatic disease represents oncogene addiction to AR activity. Androgen ablation therapy is thus a mainstay therapy against this disease, but the development of ligand-independent AR activation and persisting AR expression eventually leads to castration resistant PCa (CRPC). Therefore, down-regulation of AR expression in PCa cells may be an effective therapeutic modality. The diarylpentanoid ca27 has previously been shown to down-regulate AR expression by an unknown mechanism of action. The present work represents a …

Do Desperate Times Really Call For Desperate Measures? The Ethical Dilemma Behind The Regulation And Use Of Experimental Drugs, Lauren Kuehn

Notre Dame Journal of International & Comparative Law

This Note will argue that, unlike what many patients believe, the U.S. Food and Drug Administration (FDA) plays an invaluable and imperative role in seeking the efficacy and safety of new treatment options and drugs. The balance of interests between those who are terminally ill, who wish to see increased access to unapproved medicines; the general public, who has an interest in preserving the drug approval process; and the FDA, who has been mandated by law to safeguard the safety of the general public, creates a tension that will continue to go unresolved. Thus, the patients who continue to advocate …

Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte

University Scholar Projects

Sickle cell disease (SCD) has been shown to be associated with decreased baseline immunity and thus increased susceptibility to infection. I sought to discern possible causes of this by looking into the correlations between SCD and hematopoiesis, the immune system and the neuroendocrine system, and ultimately by conducting experiments surrounding the impaired immune system of SCD. These experiments focused on the potential causes and effects of the diminution of B-1a cells in the SCD spleen. Adoptive transfers, infections with Streptococcus pneumoniae, and histologic imaging were conducted to establish if the diminution of the B-1a cells in the SCD spleen …

Synthesis Of A Nanoscale Gold-Coated, Thermoresponsive Molecular Release System., Ryan C. Weegens

College of Arts & Sciences Senior Theses

The work presented here was performed in conjunction with an experimental group in order to prove the concept that an alternating magnetic field (AMF) could be used to induce an intramolecular cyclization to effect payload release. The system studied here consisted of a fluorophore tethered to gold-coated iron oxide nanoparticles (Fe₃O₄ NPs) via an organic linker consisting of 2 key elements: a carbonate (electrophile) and an amine (nucleophile). Connected to the carbonate was the fluorophore, anthracene, which was attached to the organic linker system by means of an oxime ether linkage. This thesis work served as the …

The Effects Of Chronic Alcohol Consumption On Ovarian Function/ Morphology, Destiny Roberts

Undergraduate Honors Theses

Chronic alcohol (ethanol) consumption has been known to affect the major organs of the body and particularly the liver. However, the effects of chronic ethanol consumption on the female reproductive system remain relatively unstudied. A convenient way to study these effects is by analyzing laboratory mice that have been fed an ethanol diet for an extended period of time and comparing them to control mice. In this study, female mice were separated into control and ethanol fed groups. The mice were placed on their specified diets and observed over the course of six weeks. The mice were fed and weighed …

A Review Of Ankylosing Spondylitis, Hannah L. Owen

Senior Honors Theses

Ankylosing spondylitis (AS) is a systemic autoimmune disorder that induces ankylosis of the spine (fusion of the vertebrae at their various joints) and inflammatory arthritis of peripheral joints among other symptoms. Overexpression of cytokines, the presence of genetic mutations not exclusive to the human leucocyte antigen (HLA)-B27 region, and environmental factors all have large roles in the progressive development of AS. Although a definitive pathology continues to be sought after, researchers believe the adaptive immune system in AS patients attacks fibrocartilaginous entheses (supportive connective tissue between bone and attached structures like tendon, ligament, and fascia).

AS markedly reduces proper systemic …
