Non-Thesis Student Work

This study aimed to look at naloxone administration in opioid overdose patients age 18-35 and its effect on patient outcomes in healthcare settings. From 1999 to 2018, deaths due to opioid overdoses experienced a six-fold increase in the United States. Naloxone is now being used in over 1% of all emergency medical service (EMS) encounters nationwide and EMS use is associated with subsequent overdose due to not receiving the community resources from the local emergency department (ED). Databases used were Umaine One Search, Nursing Reference Center Plus, and Cinahl Full Text Search. Search terms and phrases included, “naloxone availability,” “narcan ...

Biomedical Applications Of Protein Films And Polymeric Nanomaterials, Sanjana Gopalakrishnan

Doctoral Dissertations

Biomaterials are widely applied for the diagnosis and treatment of numerous diseases. In addition to fulfilling specific biological functions, biomaterials must also be non-toxic, biocompatible, and sterilizable to be regarded as safe-for-use. Polymers are excellent candidates for fabricating functional biomaterials due to their wide availability and varied properties and may be natural or synthetic. Polymer precursors are fabricated into coatings, foams, scaffolds, gels, composites, and nanomaterials for several biomedical applications. This dissertation focuses on two types of polymeric biomaterials – protein-based materials and synthetic polymeric nanoparticles. Proteins are biopolymers that naturally occur with a variety of structural and functional properties. However ...

Journal of Mind and Medical Sciences

Vesicants are compounds that cause severe toxic effects on various tissues. Such chemical action causes tissue necrosis, with clinical expression of skin lesions with a burning character and characteristic blisters. Clinical toxic effects of cutaneous vesicles are correlated with the absorbed dose and exposure time. The goals of the study are to evaluate in vitro the skin toxicity produced by the vesicant chemical compound 2-chloroethyl-ethyl sulfide (CEES), to develop a complex antidote formula, and to optimize the therapeutic efficacy by inclusion in controlled release systems. The experimental protocol aims at the in vitro evaluation of the cytotoxicity of the vesicant ...

Hypomethylating agents (HMA) prolong survival and improve cytopenias in individuals with higher-risk myelodysplastic syndrome (MDS). Only 30-40% of patients, however, respond to HMAs, and responses may not occur for more than 6 months after HMA initiation. We developed a model to more rapidly assess HMA response by analyzing early changes in patients’ blood counts. Three institutions’ data were used to develop a model that assessed patients’ response to therapy 90 days after the initiation using serial blood counts. The model was developed with a training cohort of 424 patients from2 institutions and validated on an independent cohort of 90 patients ...

The Effects Of Cannabidiol On Aqueous Humor Outflow And Trabecular Meshwork Cell Signaling, Alyssa S. Aebersold, Zhao-Hui Song

Faculty Scholarship

Intraocular pressure (IOP) is regulated primarily through aqueous humor production by ciliary body and drainage through uveoscleral and trabecular meshwork (TM) tissues. The goal of this study was to measure the effect of non-psychotropic cannabidiol (CBD) on aqueous humor outflow through TM and assess the effect of CBD on the TM cell signaling pathways that are important for regulating outflow. Perfused porcine eye anterior segment explants were used to investigate the effects of CBD on aqueous humor outflow. Cultured porcine TM cells were used to study the effects of CBD on TM cell contractility, myosin light chain (MLC) and myosin ...

Interpretable Machine Learning Models For Molecular Design Of Tyrosine Kinase Inhibitors Using Variational Autoencoders And Perturbation-Based Approach Of Chemical Space Exploration, Keerthi Krishnan, Ryan Kassab, Steve Agajanian, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

In the current study, we introduce an integrative machine learning strategy for the autonomous molecular design of protein kinase inhibitors using variational autoencoders and a novel cluster-based perturbation approach for exploration of the chemical latent space. The proposed strategy combines autoencoder-based embedding of small molecules with a cluster-based perturbation approach for efficient navigation of the latent space and a feature-based kinase inhibition likelihood classifier that guides optimization of the molecular properties and targeted molecular design. In the proposed generative approach, molecules sharing similar structures tend to cluster in the latent space, and interpolating between two molecules in the latent space ...

The Downward Spiral, Jeremy Greenwood, Nezih Guner, Karen A. Kopecky

Population Center Working Papers (PSC/PARC)

There have been more than 500,000 opioid overdose deaths since 2000. To analyze the opioid epidemic, a model is constructed where individuals, with and without pain, choose whether to misuse opioids knowing the probabilities of addiction and dying. These odds are functions of opioid use. Markov chains are estimated from the US data for the college and non-college educated that summarize the transitions into and out of opioid addiction as well as to a deadly overdose. A structural model is constructed that matches the estimated Markov chains. The epidemic's drivers, and the impact of medical interventions, are examined.

Rna Isolation In Duchenne Muscular Dystrophy (Dmd) Mice Models, Salem Abu Al-Burak

Undergraduate Student Research Internships Conference

Fibrosis is a progressive and typically irreversible disease process characterized by the excessive deposition of collagen in organs and in tissues of the musculoskeletal (MSK) system^1,2. This process, which causes loss of organ and tissue function, can be initiated by micro-traumas³, an excessive and/or prolonged immune response¹, the activation and proliferation of fibrosis-inducing progenitor cells⁴, and a pro-fibrotic extra-cellular microenvironment⁵. In parallel with the events that initiate fibrosis, genetic or environmental influences may cause cells and tissues to become predisposed to fibrosis development prior to initiation. This suggests that these cells and tissues ...

Undergraduate Student Research Internships Conference

The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.⁴ Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.¹ Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).² Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like ...

The Effects Of The Aromatase Inhibitor, Letrozole, On Lithium Chloride (Licl)-Induced Conditioned Disgust Behaviour (Anticipatory Nausea) In Male Rats, Vangel Matic

Undergraduate Student Research Internships Conference

Anticipatory Nausea (AN) is a form of classical conditioning in which the effects of a nausea-inducing toxin become associated with a specific environmental context. AN is often experienced by individuals receiving chemotherapy treatment, whereby the emetic effects of the chemotherapy agents become associated with the treatment context (i.e. hospital, clinic), such that exposure to the context alone can cause an individual to experience nausea and potentially withdraw from treatment. Chemotherapy-associated AN is suggested to have a higher incidence in females compared to males.

AN can be represented in a rodent model (conditioned disgust) through the occurrence of conditioned gaping ...

Psychedelics, Positive Psychology, And Positive Humanities, Hamide Eygoren

Master of Applied Positive Psychology (MAPP) Capstone Projects

Public and scientific interest in the effect of psychedelic drugs on wellbeing has risen significantly. Preliminary data show that psychedelic drugs, specifically classic psychedelics (DMT, psilocybin, mescaline, and LSD), may have the potential to treat mood disorders and increase wellbeing through their acute subjective effects. The acute subjective effects and enduring effects of psychedelics on wellbeing seem to relate to positive psychological frameworks (e.g., resilience factors and PERMA) considerably. Moreover, optimizing acute subjective effects indicates the importance of set (individual’s internal (mental) factors) and setting (individual’s external factors) in psychedelics administration as moderating factors. A new subfield ...
