Addiction: Physiology In Performance, Opioid Pharmacology In Character Development For The Theater, Lacey M. Smith

Honors Thesis

Actors inquire into the physical, mental, and emotional impulses of their respective characters in the effort to develop a cohesive persona for the stage. The goal of this research is to determine whether a more thorough, scientific understanding of the physiopyschological phenomena a character experiences, specifically opioid withdrawal, will aid in the depiction of symptoms on stage. The project began with a research period and culminated in physical dissemination through theater performance. Both video, audio, and text media were utilized to establish a thorough comprehension of the physiological mechanisms in opioid addiction. Further profiling of the characteristics and symptomatic episodes …

Physician Assistant Capstones, 2016 to 2019

Background Non-vitamin K oral anticoagulants have become an appealing alternative treatment for the prevention of stroke in non-valvular atrial fibrillation and in treatment of venous thromboembolism. The major limitation to the use of these drugs is the lack of reversal agents. The purpose of this review is to investigate the development and efficacy of novel agents for reversal of NOACs. Methods Two separate literature searches were conducted in the PubMed database using the terms “prothrombin complex concentrate” and “idarucizumab”, respectively. Only in vivo clinical trials involving human subjects within the last five years were included for possible analysis. Studies with …

Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir

Animal Science Undergraduate Honors Theses

One societal trend that has been gaining much traction and popularity since the 21^st century began is “organic” and/or “natural” food products. In 1999, the global market accounted for $15.2 billion dollars worth of organic food and drink, compared to the market in 2014 where we consumed $80 billion dollars worth (Willer et. al, 2016). With “natural” production of food animals however, “natural” parasite transmission may be a consequence. To that end, this experiment examines the prevalence of helminths in 110 “natural” laying hens from three regional farms and the efficacies of fenbendazole, piperazine, and levamisole on what should …

Investigating The Effects Of Increasing Anti-Ama1, Anti-Msp1, And Anti-Msp2 In Preventing Malaria Incidence, April Skipper

Selected Honors Theses

Malaria is a life-threatening illness that 3.2 billion people, half of the world's population, are at risk of contracting. In 2015, there were 214 million malaria cases and 438,000 deaths caused by the disease. It is caused by Plasmodium parasites which infect humans through the bite of the Anopheles mosquito. The four species of Plasmodium that are known to cause malaria are P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi. The symptoms of malaria greatly resemble symptoms of a common cold, so accurate diagnosis can be a challenge. Symptoms commonly include fever, headache, …

Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, Peican Zhu, Hamidreza Montazeri Aliabadi, Hasan Uludag, Jie Han

Pharmacy Faculty Articles and Research

The investigation of vulnerable components in a signaling pathway can contribute to development of drug therapy addressing aberrations in that pathway. Here, an original signaling pathway is derived from the published literature on breast cancer models. New stochastic logical models are then developed to analyze the vulnerability of the components in multiple signalling sub-pathways involved in this signaling cascade. The computational results are consistent with the experimental results, where the selected proteins were silenced using specific siRNAs and the viability of the cells were analyzed 72 hours after silencing. The genes elF4E and NFkB are found to have nearly no …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Cyclic monoterpenes are a group of phytochemicals with antinociceptive, local anesthetic, and anti-inflammatory actions. Effects of cyclic monoterpenes including vanilin, pulegone, eugenole, carvone, carvacrol, carveol, thymol, thymoquinone, menthone, and limonene were investigated on the functional properties of the cloned α₇ subunit of the human nicotinic acetylcholine receptor expressed in Xenopus oocytes. Monoterpenes inhibited the α₇ nicotinic acetylcholine receptor in the order carveol>thymoquinone>carvacrol>menthone>thymol>limonene>eugenole>pulegone≥carvone≥vanilin. Among the monoterpenes, carveol showed the highest potency on acetylcholine-induced responses, with IC₅₀ of 8.3 µM. Carveol-induced inhibition was independent of the membrane potential and could not be …

Artificial Sweeteners And Weight Gain: Fighting Or Feeding The Obesity Epidemic?, Shanna Frisch

The Science Journal of the Lander College of Arts and Sciences

Our world has developed an obsession with weight control and, as a result, has begun replacing high calorie foods with low-fat and non-caloric substitutes. Artificial sweeteners are a widely used solution to this growing problem. Though the intention when using artificial sweeteners is to lose weight, studies have shown that the opposite sometimes occurs. Researchers attempt to explain this surprising phenomenon with multiple hypotheses. Lack of appetite suppression and reward response may cause individuals to search for more food and to consume more calories. Artificial sweeteners can also have negative affects on biological mechanisms such as resting metabolic rate, as …

Synthesis And Biochemical Evaluation Of 3-Phenoxy-1,4-Diarylazetidin-2-Ones As Tubulin-Targeting Antitumor Agents, Thomas F. Greene, Shu Wang, Lisa M. Greene, Seema M. Nathwani, Jade K. Pollock, Azizah M. Malebari, Thomas Mccabe, Brendan Twamley, Niamh O'Boyle, Daniela M. Zisterer, Mary J. Meegan

Articles

Structure-activity relationships for a series of 3-phenoxy-1,4-diarylazetidin-2-ones were investigated leading to the discovery of a number of potent antiproliferative compounds, including trans-4-(3-hydroxy-4-methoxyphenyl)-3-phenoxy-1-(3,4,5-trimethoxyphenyl)azetidin-2-one (78b) and trans-4-(3-amino-4-methoxyphenyl)-3-phenoxy-1-(3,4,5-trimethoxyphenyl)azetidin-2-one (90b). X-ray crystallography studies indicate the potential importance of the torsional angle between the 1-phenyl ‘A’ ring and 4-phenyl ‘B’ ring for potent antiproliferative activity, and that a trans configuration between the 3-phenoxy and 4-phenyl rings is generally optimal. These compounds displayed IC₅₀ values of 38 nM and 19 nM respectively in MCF-7 breast cancer cells, inhibited the polymerization of isolated tubulin in vitro, disrupted the microtubular …

Piperlongumine (Piplartine) And Analogues: Antiproliferative Microtubule-Destabilising Agents, Mary J. Meegan, Seema M. Nathwani, Brendan Twamley, Daniela M. Zisterer, Niamh O'Boyle

Articles

Piperlongumine (piplartine, 1) is a small molecule alkaloid that is receiving intense interest due to its antiproliferative and anticancer activities. We investigated the effects of 1 on tubulin and microtubules. Using both an isolated tubulin assay, and a combination of sedimentation and Western blotting, we demonstrated that 1 is a tubulin-destabilising agent. This result was confirmed by immunofluorescence and confocal microscopy, which showed that microtubules in MCF-7 breast cancer cells were depolymerised when treated with 1. We synthesised a number of analogues of 1 to explore structure-activity relationships. Compound 13 had the best cytotoxic profile of this series, …

Reduction in testosterone levels in men during aging is associated with cognitive decline and risk of dementia. Animal studies have shown benefits for testosterone supplementation in improving cognition and reducing Alzheimer’s disease pathology. In a randomized, placebo-controlled, crossover study of men with subjective memory complaint and low testosterone levels, we investigated whether testosterone treatment significantly improved performance on various measures of cognitive functioning. Forty-four men were administered a battery of neuropsychological tests to establish the baseline prior to being randomly divided into two groups. The first group (Group A) received 24 weeks of testosterone treatment (T treatment) followed by 4 …

Effects Of Repeated Quetiapine Treatment On Conditioned Avoidance Responding In Rats, Jun Gao, Min Feng, Natashia Swalve, Collin Davis, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

The present study characterized the behavioral mechanisms of avoidance–disruptive effect of quetiapine in the conditioned avoidance response test under two behavioral testing (2 warning signals vs. 1 warning signal) and two drug administration conditions (subcutaneous vs. intravenous). In Experiments 1 and 2, well-trained adult male Sprague-Dawley rats were tested under the subcutaneous (s.c.) quetiapine treatment (5.0, 15.0, 25.0, 50.0 mg/kg) for 7 days in a novel procedure consisting of two conditioned stimuli (CS) (white noise serving as CS1 and pure tone as CS2). Only the highest dose (50.0 mg/kg) produced a persistent suppression of the avoidance response without impairing the …

The Effectiveness Of A Preoperative Multimodal Antiemetic Regimen On Reducing Early Postoperative Nausea And Vomiting In Total Joint Arthroplasty Patients, Jerry Mosley

Doctoral Projects

Postoperative nausea and vomiting (PONV) occurs frequently in all types of surgeries including after total joint orthopedic procedures. The resulting PONV can lead to many unwanted occurrences including immobilization, distress, and many serious adverse health complications. These unwanted occurrences may then lead to increased cost to the patient and healthcare facility. Administration of a preoperative multimodal regimen known to reduce PONV has the potential to reduce such unwanted anesthetic side effects influencing a reduction in overall healthcare cost. The purpose of this study is to determine the effectiveness of the preoperative kit which includes the administration of metoclopramide, famotidine, ondansetron, …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations and Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

The Controversy Of Vaccinations, Nicholas G. Aboreden

The Kabod

Recently vaccination has become a controversial topic. There is a growing number of people who believe that vaccines carry great health risks to patients and therefore refuse to be vaccinated or to vaccinate their children. This ill-informed view of immunizations is beginning to cause serious problems in the United States as growing numbers of disease cases are being seen. A closer look into the science of vaccines and the benefits they have brought, clearly show that not only do vaccines carry very little risk to patients, but they are responsible for the eradication and reduction of multiple debilitating diseases.

Application Of Ichip To Grow “Uncultivable” Microorganisms And Its Impact On Antibiotic Discovery, Rinzhin T. Sherpa, Caretta J. Reese, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Purpose. Antibiotics have revolutionized modern medicine, allowing significant progress in healthcare and improvement in life expectancy. Development of antibiotic resistance by pathogenic bacteria is a natural phenomenon; however, the rate of antibiotic resistance emergence is increasing at an alarming rate, due to indiscriminate use of antibiotics in healthcare, agriculture and even everyday products. Traditionally, antibiotic discovery has been conducted by screening extracts of microorganisms for antimicrobial activity. However, this conventional source has been over-used to such an extent that it poses the risk of “running out” of new antibiotics. Aiming to increase access to a greater diversity of microorganisms, …

Rotavirus (RV) infections cause severe diarrhea in infants and young children worldwide. Vaccines are available but cost prohibitive for many countries and only reduce severe symptoms. Vaccinated infants continue to shed infectious particles, and studies show decreased efficacy of the RV vaccines in tropical and subtropical countries where they are needed most. Continuing surveillance for new RV strains, assessment of vaccine efficacy, and development of cost effective antiviral drugs remain an important aspect of RV studies. This study was to determine the efficacy of antioxidant and anti-inflammatory stilbenoids to inhibit RV replication. Peanut (A. hypogaea) hairy root cultures were induced …

Molecular Overlap In The Regulation Of Sk Channels By Small Molecules And Phosphoinositides, Miao Zhang, Xuan-Yu Meng, Ji-Fang Zhang, Meng Cui, Diomedes E. Logothetis

Pharmacy Faculty Articles and Research

Phosphatidylinositol 4,5-bisphosphate (PIP2) directly interacts with the small-conductance Ca2+-activated K+ 2-a (SK2-a) channel/calmodulin complex, serving as a critical element in the regulation of channel activity. We report that changes of protein conformation in close proximity to the PIP2 binding site induced by a small-molecule SK channel modulator, NS309, can effectively enhance the interaction between the protein and PIP2 to potentiate channel activity. This novel modulation of PIP2 sensitivity by small-molecule drugs is likely not to be limited in its application to SK channels, representing an intriguing strategy to develop drugs controlling the activity of the large number of PIP2-dependent proteins.
